1 A recalcitrant phenomenological disagreement

1.1 Is inner awareness ubiquitous?

Is your conscious ‘outer awareness’ of the world always accompanied by a conscious ‘inner awareness’ of that very experience? This is a question about your phenomenology—about what it’s like to undergo the experience you are having. The same question can be expressed in a number of different ways: when you experience some event do you also experience your experience?; do your conscious states involve a self-consciousness of that very state?; when you are perceptually aware of your environment, are you also aware of your awareness? Introspection certainly seems to yield awareness of one’s own experience, but the question is whether your non-introspective experiences are characterised by a kind of inner awareness too. One camp answers ‘yes’ to these questions: they report that inner awareness is a ubiquitous feature of their phenomenology. The other camp answers ‘no’ to these questions: they report that their phenomenological reflection reveals no such ubiquitous property.

One possibility here is that both sides are getting their own phenomenology right: the yes-camp has one kind of experience, the no-camp has a different kind, and both camps are accurately reporting what their own experiences are like. Although this suggestion has the attraction of making everybody right, I think all sides can agree that it is wildly implausible. If there is such a thing as this non-introspective inner awareness, why would it be a ubiquitous feature of some people’s experience but not others? The more likely situation is that both camps have the same kind of experience but at least one camp is describing their phenomenology inaccurately. So the real question is whether the following phenomenological thesis is true:

The Ubiquity of Inner Awareness Thesis (UIA): all conscious states of normal adult humans are characterised by an inner awareness of that very state.

Those who affirm this phenomenological thesis are UIA-Backers. Those who do not affirm this thesis, including those who actively deny it, are UIA-Skeptics.Footnote 1 The UIA-Backers and UIA-Skeptics offer conflicting views of what our conscious experience is like.

UIA holds that we are always aware of our concurrent experience. It is important to recognise that this thesis does not place demanding constraints on the way in which we are aware of our experience. Our inner awareness does not, for instance, need to be an attentive awareness. Nor need it involve the application of concepts to our own experience.Footnote 2 Nor does it have to be an objectual awareness—that is, an awareness that presents its target as an entity that exists independently of our being aware of it. It may not even require an egological representation of ourselves as the subjects of that experience—a state might be self-conscious in the sense of yielding consciousness of itself without being self-conscious in the sense of yielding consciousness of the subject that bears it.Footnote 3 So if our inner awareness is inattentive, non-conceptual, non-objectual and non-egological that would be quite consistent with the truth of UIA. One constraint that UIA does place on our inner awareness is that it be conscious awareness. Some take ‘awareness’ to be synonymous with ‘consciousness’ but others allow awareness to come in non-conscious forms. The ubiquity of non-conscious inner awareness—a possibility I will consider in due course—would not entail the truth of UIA. By ‘awareness’ I shall mean conscious awareness. Some of the more demanding features mentioned might be required for introspective awareness of one’s experience, but UIA does not claim that all experiences are introspected.Footnote 4 Kriegel holds that introspection brings into focal attention an inner awareness that is otherwise only a peripheral aspect of our experience (Kriegel 2009a, p. 183). Zahavi draws attention to a crucial distinction made in the phenomenological tradition between reflective and pre-reflective self-consciousness (e.g. 2006, p. 5). Reflective self-consciousness is achieved only when we introspect, but the suggestion is that there is a more primitive pre-reflective self-consciousness that is a constant background presence in experience.Footnote 5

1.2 Theoretical implications of UIA

UIA is an interesting thesis about the phenomenology of normal adult humans. More than that though, it has significant implications for our theorising about consciousness. Importantly, some have used UIA as the basis for bolder claims about the nature of consciousness. First, one might draw an abductive inference from UIA to the unrestricted thesis that all possible conscious experiences are characterised by an inner awareness of that very state. On this view, UIA offers us an insight into the invariant structure of conscious experience, allowing us to conclude that the experiences of abnormal adult humans, of human infants and of conscious non-human animals must also all be characterised by inner awareness. Second, from this unrestricted phenomenological thesis one might draw an inference to the metaphysical conclusion that inner awareness is what makes conscious mental states conscious at all. This comes out vividly in Kriegel’s self-representationalist theory of consciousness according to which a mental state is conscious in virtue of suitably representing itself (Kriegel 2009a). Neither of these inferences is beyond reproach. Mehta, for instance, casts serious doubt on both (2013, pp. 361–363). But the fact that UIA is used to drive such substantive theoretical claims gives us all the more reason to assess its credibility.

Even if UIA is not used to motivate theoretical claims about consciousness, it can certainly be used to test such claims. Higher-order representation (HOR) theories claim that we are aware of a mental state M only when we suitably represent it via some distinct higher-order mental state M* (e.g. Rosenthal 1986). Some advocates of UIA have suggested that HOR theories are incompatible with UIA (Kriegel 2009a, pp. 124–125). If UIA is true, we are not just aware of M but also of our awareness of M. To accommodate this the HOR theorist might posit some third mental state M** in virtue of which we are aware of M* representing M. But this merely pushes the problem up a level, leaving us unaware of the awareness bestowed by M**. Assuming we can rule out an infinite hierarchy of mental states, it looks like the truth of UIA is at odds with the truth of HOR theory.

‘One-state’ theorists have attempted to avoid this objection whilst maintaining something of the spirit of HOR theory. Echoing a move made by Brentano (1874/1924), they suggest that consciousness involves a single mental state that represents both the world and itself. The hope is that such reflexive representations can yield awareness of our own awareness. This strategy has been developed in a number of competing ways, and the resulting theories can again be tested by asking whether they accommodate the truth of UIA. Kriegel, for instance, suggests that this reflexive representation is achieved when a lower- and higher-order mental state appropriately combine to form a single complex mental state. But there is a genuine worry that this kind of internal representational division would entail the same kind of regress that threatens HOR theory.Footnote 6

The truth of UIA would be a crucial datum for theorising about consciousness. Conversely, if UIA is false this too would have important theoretical consequences, cutting off any lines of argument premised on UIA. My aim in this paper is not to evaluate theoretical claims about consciousness, nor to assess the validity of any inferences made from UIA to some theoretical conclusion. Rather, my aim is to look closely at this putative phenomenological datum itself, putting aside any theoretical matters that might cloud our assessment.

1.3 Strategies for resolving the dispute

UIA-Backers claim to have phenomenological justification for their belief in UIA.Footnote 7 Kriegel holds that ‘…peripheral inner awareness is simply phenomenologically manifest’ (2009a, p. 50) and Zahavi suggests that accurate phenomenological description is ‘the best argument to be found’ for thinking that non-introspective experience is characterised by pre-reflective self-consciousness (2006, p. 24). But UIA-Skeptics claim not to find any such feature in their experience. Mehta reports ‘[w]hen I conduct phenomenological investigation into any peripheral awareness of my experiences, attempting to set aside any theoretical prejudices, I haven’t a clue whether I’ve ever had such peripheral awareness’ (2013, p. 364). And Gennaro states ‘[i]t does not seem to me that I am consciously aware (in any sense) of my own experience when I am, say, consciously attending to a play or the task of building a bookcase’ (2008, p. 48). Schear (2009, p. 100) reports that his polling on the matter reveals no consensus for or against UIA and my own informal polling reveals much the same.

Faced with this recalcitrant phenomenological disagreement, what can we do to resolve the dispute? Two broad strategies present themselves. The via positiva strategy is to establish indirect evidence for UIA. On this strategy, UIA-Backers identify particular features of experience—features that their opponents can agree are genuine—and then argue that UIA is the best explanation of these features. The challenge for UIA-Skeptics is to resist these inferences. The via negativa strategy is to explain why one side has got their own phenomenology wrong. The task for the UIA-Backers is to explain why the UIA-Skeptics have failed to recognise a ubiquitous feature of their phenomenology, while the task for the UIA-Skeptics is to explain why the UIA-Backers are under the illusion that their experiences have a property that they in fact lack.

In Sect. 2 I explore the three leading implementations of the via positiva strategy. I argue that, in all three cases, the UIA-Skeptics can offer their own credible explanations of the data cited without having to posit UIA. Moving on to the via negativa strategy, I consider four proposals put forward by UIA-Backers designed to explain away skepticism about UIA, and four proposals put forward by UIA-Skeptics designed to explain away any attraction to UIA. I argue that no proposal takes seriously enough the intuitions of the opposing camp. I conclude that none of the moves made in the dispute over UIA have the dialectical purchase needed to break the phenomenological stalemate.

In Sect. 4 I introduce my own model of inner awareness which offers a novel alternative to the entrenched positions in this debate. I suggest that all conscious experiences of normal adult humans are characterised by an affordance of introspectability. That is, ordinary non-introspective experience does not involve the subject being aware of her experience but does involve the subject being aware of her potential to become aware of her experience. This ‘Affordance Model’ denies UIA, officially putting me in the UIA-Skeptic camp. Unlike the established skeptical positions though, the Affordance Model reflects something of the spirit of UIA. As such I regard it as a compromise position that, instead of simply adopting a hard-line stance, takes seriously the intuitions of both camps. Furthermore, I argue that this model is much better equipped than hard-line views to explain why its opponents have got their own phenomenology wrong.

2 The via positiva strategy

2.1 Three via positiva arguments for UIA

(i) Reportability Whenever we are in a conscious mental state, we are easily able to report on that very mental state when prompted.Footnote 8 This is a datum that the UIA-Skeptic ought to accept: it is a highly plausible claim about consciousness, and its plausibility does not rely on any presupposition that UIA is true. UIA-Backers argue that the best explanation of this datum is that all consciousness includes a peripheral/pre-reflective consciousness of itself. Zahavi, drawing explicitly on Sartre, argues as follows:

If I am engaged in some conscious activity, such as the reading of a story, my attention is neither on myself nor on my activity of reading, but on the story. But if my reading is interrupted by someone asking me what I am doing, I reply immediately that I am (and have for some time been) reading; and the self-consciousness on the basis of which I answer the question is not something acquired at just that moment but a consciousness of myself which has been present to me all along. (2004, p. 84)

Since the experience is one of immersion in the story, it would be implausible to explain the report by saying that the subject was explicitly introspecting his experience whilst reading. Since the report is immediate and effortless, it would be implausible to say that the report was made on the basis of an introspection performed by the subject after he was interrupted. We are thus encouraged toward the conclusion that the subject’s experience of the story is characterised by a non-introspective awareness of that very experience. And since we (normal adult humans) are always able to report on our conscious states, we can infer that our experiences are always characterised by this inner awareness.Footnote 9 So regardless of her prior phenomenological intuitions, the UIA-Skeptic ought to infer that UIA is true after all.

(ii) No Surprises At present you are, I assume, visually perceiving the words before you. Now start to introspect. What do you find? Presumably you find that you are undergoing a visual experience as of reading the words before you. I imagine that this doesn’t come as news to you—I’m not surprised that you find this experience on introspecting so it would be very odd if you were surprised! This is representative of a general truth about introspection: when we introspect we are unsurprised to find just the experience we do. Perhaps introspection can reveal specific properties of our experience that are surprising, but it remains the case that finding the experience itself never feels like a substantive discovery.

This is a datum about consciousness—specifically about introspective consciousness—that the UIA-Skeptic ought to accept. UIA-Backers suggest that the best explanation of this datum is that we are already aware of our experience prior to introspecting it. Kriegel explains that ‘[i]f conscious states were states we were aware of, then they would not be surprising to notice when we turned our attention onto them’ (2009a, p. 307). Introspection cannot surprise us because it doesn’t make us aware of anything we weren’t aware of prior to introspecting. On Kriegel’s view, introspection simply brings into focus something of which we were already aware peripherally. Or, in Zahavi’s framework, introspection brings into reflective awareness that which was already given to us pre-reflectively. Thus the ‘no surprises’ datum ought to convince the UIA-Skeptic that UIA is true.

(iii) Nothing Dramatic The last via positiva argument I will consider is based on an observation about how it feels to introspect. When you make the transition from perceiving your current environment to introspecting your current perceptual experience, does it feel as though you are introducing a wholly new representation into your experience? Most would say that introspection feels less dramatic than this. Kriegel holds that ‘…introspecting feels more like a phenomenologically light shifting around of attention than like a dramatic mental act that produces a completely new awareness’ (2009a, p. 186). Introspection is not like opening our eyes, revealing visible objects of which we were previously unaware. Rather, introspection is more like visually attending to an object that we were previously seeing inattentively.

The UIA-Backers explain this datum by saying that introspection really doesn’t produce any new awareness: it seems undramatic because it is undramatic. Introspecting is a modest shifting around of attention, or a subtle transition from pre-reflective to reflective awareness. In other words, introspection merely enhances the inner awareness that is already contained in our non-introspective experience. So given this datum about how the act of introspection feels, the UIA-Skeptic ought to infer that UIA is true.Footnote 10

2.2 The skeptical response

How can the UIA-Skeptic respond to these via positiva arguments? One option is to reject the putative data, but this would come at the cost of having little dialectical force against those who find the data plausible. A better route for the skeptic is to find a way of accommodating the data whilst avoiding UIA. UIA may well explain the data cited, but is it the best explanation? If the UIA-Skeptic can provide explanations of the data that are at least as plausible as those provided by the UIA-Backer, then the inference to UIA can be blocked.Footnote 11

(i) Reportability The fact that we can report on our concurrent conscious activity indicates that we have knowledge of our conscious states as we undergo them. Claiming, as the UIA-Backer does, that we are aware of our concurrent conscious state is one way of accounting for this epistemic situation. But it is not the only way. At any given time, we have a great deal of non-conscious knowledge—things that we know but which do not figure in our experience. As Schear explains:

…the move from an epistemological self-relation (knowing what I am doing in doing what I am doing) to a phenomenological self-relation (experiencing myself doing what I am doing in doing what I am doing) is a move, and it is not an obvious move to make. (2009, p. 101)

Avoiding this unwarranted move, the UIA-Skeptic can explain the reportability of conscious states by saying that our conscious states are accompanied by a concurrent non-conscious knowledge of that very state (Thomasson 2005). Here we have a perfectly credible explanation of the data cited that involves no appeal to inner awareness.Footnote 12

(ii) No Surprises Once the UIA-Skeptic has posited an ever-present non-conscious knowledge of our concurrent conscious state, she is also in a position to accommodate the ‘no surprises’ datum. When we introspect we are unsurprised by the experience we find because we already knew about that experience prior to introspection. The UIA-Backer assumes that this knowledge takes the form of inner awareness, but the UIA-Skeptic can reject that assumption and hold that the relevant knowledge is non-conscious.Footnote 13 Consider again the introspection of your perceptual experience of the words before you. This perceptual experience is unsurprising to you because you already knew you were having this experience before you began to introspect. But since this knowledge was non-conscious, your non-introspective experience of the words was exhausted by your outer awareness of the world. There is no need to infer that inner awareness was contributing to your phenomenology.Footnote 14

(iii) Nothing Dramatic A UIA-Skeptic might adopt a model of introspection according to which we observe our own experiences when, and only when, we begin to introspect (e.g. Armstrong 1968). The fact that introspection does not feel like such a ‘dramatic’ act would count against such a view. Most UIA-Skeptics, however, would not wish to adopt such a model of introspection. A number of more promising models of introspection are available according to which introspection is, in the relevant sense of the term, an undramatic act. For instance, Thomasson draws on the influential Husserlian notion of bracketing:

…the idea of bracketing in phenomenology is to preserve both force and content of the original experience…but use the brackets to disconnect it from our ordinary world-directed concern so that it can be studied as a phenomenon, a way of experiencing the world, rather than being put to use in our engagement with the world… (2005, p. 125)

She goes on to describe this transformation of our consciousness as ‘…a shift of attitude within our experiences: regarding them merely as appearances, as representing contents, rather than simply using them to acquire information about the world’ (2005, pp. 126–127).Footnote 15 If accurate, this would explain why introspection does not feel dramatic without presupposing that inner awareness is present in the background of our non-introspective experiences.Footnote 16 The UIA-Skeptic need not commit herself to the Husserlian model of phenomenological knowledge here. Rather, she can make the weaker claim that there is no need to posit UIA to explain the ‘nothing dramatic’ datum since alternative models are available with just as much explanatory promise.Footnote 17

The via positiva strategy has failed to tip the balance in favour of UIA. Although credible explanations of the data cited can be provided by UIA, it is far from clear that these are the best explanations as plausible competing explanations are available that do not posit UIA. As such, the UIA-Backer has said nothing that ought to convince the UIA-Skeptic to switch sides. In fact, it seems that preferences for one explanation over another are governed by one’s prior attitude toward the truth of UIA. So, far from providing an objective way of resolving the dispute, the via positiva strategy has no real dialectical purchase, leaving us with the same recalcitrant phenomenological disagreement with which we started.Footnote 18 Although my review of the via positiva strategy is far from comprehensive I think it offers a fair assessment of what the literature has to offer, so for the remainder of the paper I will assume that no existing version of the strategy succeeds.

3 The via negativa strategy

The aim of the via negativa strategy is to establish a credible explanation of why the opposing camp has ended up misdescribing their own phenomenology. A successful implementation of this strategy must cast serious doubt on the opposing position and ought to shake opponents’ confidence in their phenomenological reports. This strategy does not seem to have been implemented with any great enthusiasm by UIA-Backers. Kriegel introduces four quick considerations designed to explain away resistance to UIA (2009a, pp. 51–52), but I will argue that none of these considerations has any real force against the UIA-Skeptic. The strategy has been adopted much more enthusiastically by UIA-Skeptics. I will focus on arguments put forward by Thomasson (2006), Gennaro (2008), Schear (2009) and Mehta (2013), and again will conclude that they fail to break the dialectical stalemate between the two camps.

One option available to both sides is to say that their opponents are simply reflecting on their phenomenology badly. But this argument would clearly lack any dialectical purchase as the opposing camp can simply turn the same argument around. Furthermore, since it is implausible that an opponent is a bad phenomenological investigator across the board, it is unwarranted to suggest that she is making a careless mistake in the case of her investigation of inner awareness. I think two general lessons can be extracted from this:

  1. (I)

    A successful via negativa argument cannot be applicable against both camps with equal force.

  2. (II)

    A successful via negativa argument cannot attribute to the opponent a kind of mistake that she is not disposed to make in contexts other than the assessment of UIA.

Although these two rules are quite demanding, a proper appreciation of what is required of the via negativa strategy reveals them to be appropriate. Consider a scenario in which we have a compelling positive theoretical argument for our preferred position. This would leave us with the residual task of explaining why our opponent has got things wrong. In such a situation, the demands placed on our explanation would be relatively weak. It wouldn’t matter, for instance, if our opponent could generate an inverted explanation of why our intuitions are wrong because we would not be relying on our intuitions to make our case: rather, our intuitions would be backed up by a compelling theoretical argument. It is important to recognise that this is not the scenario in which we currently find ourselves. I have argued already that theoretical considerations do not resolve the debate. Consequently, the via negativa strategy needs to provide a self-standing argument for one’s preferred position. In light of this, the two demanding rules I have introduced are quite appropriate. I will argue that none of the via negativa arguments that have been put forward manage to satisfy both rules.

3.1 Four via negativa arguments against the UIA-Skeptic

(i) Unimpressiveness Kriegel notes that ‘…peripheral inner awareness is not as phenomenologically impressive as, say, the qualitative character of color experience. But the common tendency to take color experiences as the gold standard of phenomenology…may set the bar too high’ (2009a, p. 51). The suggestion is that UIA-Skeptics fail to notice the inner awareness that characterises their experience because it is such a subtle feature. This may well explain why inner awareness is harder to spot than more striking aspects of our phenomenology, such as the reddish quality of our visual experience. But why should we think that the UIA-Skeptic has carelessly failed to consider the more subtle aspects of his phenomenology when he searches for inner awareness? After all, the UIA-Skeptic isn’t inclined to deny the existence of other subtle aspects of his phenomenology. Gennaro, for example, reports that a peripheral awareness of his thoughts makes a subtle contribution to his phenomenology (2008, p. 44), so why would he fail to recognise the subtle presence of peripheral inner awareness? The argument from unimpressiveness breaks the second rule identified above: it attributes to the UIA-Skeptic a kind of mistake—in this case a failure to recognise unimpressive features of their phenomenology—that he is not disposed to make in contexts other than the examination of inner awareness. Perhaps Kriegel could supplement his argument with an explanation of why the UIA-Skeptic makes this mistake specifically in the context of inner awareness, but it would then be this supplementary move that is doing the real philosophical work, rendering the appeal to unimpressiveness somewhat redundant.

(ii) Unintrospectability Kriegel’s next line of argument is that we normally identify features of our phenomenology by attending to them. In the case of peripheral inner awareness though, ‘…if we attempt to turn our attention to it, it inevitably transforms into focal inner awareness’ (2009a, p. 52). We can translate the same point into Zahavi’s framework: our pre-reflective self-consciousness cannot be revealed by explicit reflection on our experience, because such reflection transforms our self-consciousness from pre-reflective to reflective. If inner awareness is unintrospectable, how do UIA-Backers like Kriegel know that it is there? Kriegel suggests that we have ‘…a general impression of peripheral inner awareness from our ordinary, non-introspective consciousness’ (2009b, p. 375). This account might explain why peripheral inner awareness is harder to spot than features of phenomenology that can simply be attended to explicitly. Again though, the problem is that UIA-Skeptics don’t generally make the mistake of denying the existence of inattentive aspects of their phenomenology. Mehta, for instance, acknowledges that he has an inattentive awareness of his keyboard as he types (2013, p. 364). As such, Kriegel still owes us an explanation of why the UIA-Skeptic would make such a mistake when it comes to peripheral inner awareness.

(iii) Background Hum Kriegel notes that ‘[i]t is in general difficult to notice even stimuli that are constant for a relatively short time, such as the hum of the refrigerator pump. If peripheral inner awareness is indeed ubiquitous, its constancy throughout our waking life would account for the fact that it is so phenomenologically elusive’ (2009a, p. 52). Our inner awareness is thus like a humming fridge that never stops. Since we never have an experience lacking this phenomenological feature, we are unable to contrast our conscious states and bring our peripheral inner awareness ‘into sharper relief’ (2009a, p. 52). The problem with this line of argument should be clear: although it might explain why peripheral inner awareness is harder to spot than features that vary between experiences, this does not explain the UIA-Skeptic’s mistake. Presumably the skeptics aren’t such careless phenomenologists that they would deny the existence of the background hum of the fridge, even when prompted by opponents who claim that such a humming is present. So why would they be making an analogous mistake in the case of inner awareness?

Overall, Kriegel’s attempts to implement the via negativa strategy are inadequate. They may well explain someone’s initial resistance to UIA—which is, to be fair, all Kriegel claims they succeed in doing (2009a, p. 52)—but they cannot explain the mistake of a considered UIA-Skeptic who has carefully examined her experience but is still unable to find the putative background hum of inner awareness. Kriegel’s arguments fail to satisfy the second rule: they attribute to the skeptic a kind of mistake when reflecting on inner awareness that she is not otherwise disposed to make.

3.2 Four via negativa arguments against the UIA-Backer

Many UIA-Skeptics are acutely aware of the need to account for what they take to be the phenomenological mistake of their opponents (Thomasson 2006, p. 7; Gennaro 2008, pp. 48–49; Schear 2009, p. 101). Mehta, for instance, asks ‘…how could Kriegel and those like him have gotten their phenomenology wrong?’ (2013, p. 365). I consider the four main answers offered to this question but find them all wanting. The first and second fail to offer arguments that cannot be turned around with equal force by the UIA-Backer. The third and fourth attribute to the UIA-Backer a kind of mistake that he is not otherwise disposed to make.

(i) Theoretical Bias One of the main problems we face when assessing the veracity of a subject’s phenomenological reports is that those reports can be influenced by the background theoretical commitments of the subject. As outlined in Sect. 1, UIA is bound up with a number of theoretical claims about consciousness. The suggestion is that UIA-Backers have particular theoretical beliefs that skew the way they regard their own experience.Footnote 19 Kriegel, for instance, claims that his unbiased phenomenological commitment to UIA drives his Self-Representationalist theory of consciousness. But perhaps, instead, it is a background theoretical commitment to Self-Representationalism that underwrites the convictions he has about his phenomenology. On this account, the theoretical judgment that one’s experience must always be characterised by inner awareness leads to the erroneous phenomenological judgement that one’s experience is always characterised by inner awareness.

It is hard to deny that theoretical commitments sometimes lead one’s phenomenological judgements astray, so to that extent the argument from theoretical bias has some credibility. Despite this, it is not an argument that will help us break the phenomenological stalemate at hand. The problem is that all parties are coming into the discussion of UIA with certain background theoretical opinions about consciousness. So although it is credible that UIA-Backers are making theoretically biased phenomenological judgements, it is equally credible that it is the judgements of the UIA-Skeptic that are biased. Some claim, for example, that inner awareness requires a reflective act (e.g. Thomasson 2005). Perhaps, then, the conviction that non-introspective experiences ought not to be characterised by inner awareness leads UIA-Skeptics to the erroneous phenomenological judgement that their experiences are not so characterised. In other words, the argument from theoretical bias cuts both ways, so cannot tip the balance of the debate one way or the other.

(ii) The Fridge Light Fallacy Whenever you open the fridge door you find that the fridge light is on. From this you might infer that the fridge light is always on, even when the door is closed. But, of course, this inference would be mistaken as it is the act of opening the door that makes the light turn on. The proposal is that investigating whether we are aware of our conscious states can lead us to make an analogously fallacious inference. Schear argues:

…to reflect on the structure and character of our own experience is an intensely self-conscious enterprise. As soon as we’ve set off on the investigation, we’ve ‘‘opened the refrigerator.’’ Unsurprisingly, self-consciousness turns up wherever we look. And then we proceed to call it ‘‘pre-reflective’’ to ease the pangs of our guilty phenomenological conscience. (2009, p. 101)

Whenever we introspect we find an experience that is clearly characterised by an inner awareness of that very experience. From this, the UIA-Backer infers that his non-introspective experiences must also involve inner awareness, albeit in an attenuated form. But what he should have recognised is that the very act of introspection is what introduced inner awareness into his experience, meaning the inference is mistaken.Footnote 20

As with the argument from theoretical bias, this proposal identifies a kind of mistake to which we are genuinely vulnerable. Again though, the argument fails to break the phenomenological stalemate. UIA-Backers can simply reverse the argument and suggest that UIA-Skeptics fail to recognise that introspection ‘switches off’ our peripheral/pre-reflective awareness. If UIA is true, there is a pre-reflective inner awareness that all our non-introspective experiences have. Perhaps the UIA-Skeptic makes the following mistake: whenever she introspects, she finds only focal/reflective inner awareness and never the peripheral/pre-reflective inner awareness posited by the UIA-Backer. From this she infers that none of her experiences are characterised by pre-reflective inner awareness. But what she should have recognised is that the act of introspection is what removed the peripheral/pre-reflective inner awareness from her experience, replacing it with focal/reflective inner awareness. This is effectively the thrust of Kriegel’s via negativa argument from unintrospectability discussed above. Yet again, the phenomenological stalemate persists.

(iii) The Non-Conscious/Conscious Confusion The UIA-Skeptic is free to grant that whenever we are in a conscious state, we have a concurrent knowledge of that conscious state. So long as the knowledge is itself non-conscious, this entails no commitment to UIA. Perhaps the UIA-Backer is then making the following error: he correctly recognises that he always has knowledge of his concurrent conscious state, but mistakes this non-conscious knowledge for conscious knowledge. In other words, when the UIA-Backer reports that inner awareness is a ubiquitous feature of his experience, he is reading his non-conscious knowledge into his phenomenology. This suggestion comes out explicitly in the passages from Schear discussed in Sect. 2.2.Footnote 21 One of the attractions of this proposal is that it does not uncharitably suggest that the UIA-Backer is entirely misguided in his support of UIA. Rather, he has latched onto a genuine truth about the epistemic status of consciousness, but then made a mistake about how best to understand this epistemic status.

The problem with this proposal is that UIA-Backers are not generally inclined to confuse conscious and non-conscious knowledge. At any given time, Uriah Kriegel knows his name and could report what his name is when asked. But he is not (I assume) inclined to read this non-conscious knowledge into his experience: he does not posit a ubiquitous peripheral name-awareness to explain his epistemic situation. So why would he be making an analogous mistake in the case of his non-conscious knowledge of his concurrent conscious state? As it stands, this argument fails to offer a credible explanation of the UIA-Backer’s mistake. At best, it is an incomplete proposal that needs to be supplemented with an account of why the UIA-Backer is vulnerable to this mistake in the case of knowledge of consciousness and not other cases of knowledge.

(iv) The Disposition/Actualisation Confusion The UIA-Skeptic is free to grant that all conscious states are introspectable, or more cautiously that all typical conscious states of normal adult humans are introspectable. On this view, whenever a subject is conscious she has the potential to gain an inner awareness of their concurrent conscious state. But this disposition is only actualised when we explicitly introspect, never during our ordinary non-introspective experience.Footnote 22 The suggestion is that UIA-Backers confuse this constant dispositional property of experience with the actualisation of that disposition, leading them to report that inner awareness is a constant actual presence in their experience. Thomasson argues that ‘…it is our ability to have immediate first-person knowledge of our own experiences … that leads many to think of them as states we are continually aware of’ (2006, p. 8). Similarly, Schear hypothesises that UIA-Backers are guilty of the ‘category mistake’ of ‘…construing the presence of a capacity for self-consciousness as the actualization of that capacity in our experience of the world beyond ourselves’ (2009, p. 99).Footnote 23 Like the previous via negativa argument, this view suggests that the UIA-Backer has got something right—he has recognised that our capacity for inner awareness is bound up with all of our experiences. His mistake is to misconstrue the potential presence of inner awareness as an occurrent presence.

Again, the problem with this argument is that UIA-Backers are not generally inclined to mistake dispositional properties of experience for the actualisation of that property. At any given time, Dan Zahavi has the potential to report on his concurrent experience. But he is not (I assume) inclined to say that this potential is in some way actualised for all experiences: he does not, for instance, suggest that all experiences are accompanied by a background inner monologue describing that very conscious state. So why would he be making an analogous mistake in the case of his potential to gain inner awareness of his concurrent experience? The proposed explanation is at best incomplete. Interestingly, Schear recognises that there’s some further explaining to do here, so cites the fridge light fallacy to explain why UIA-Backers are vulnerable to a category mistake regarding inner awareness that they wouldn’t otherwise be inclined to make (2009, p. 101). As we have already seen though, the appeal to the fridge light fallacy fails to yield any dialectical traction. Yet again, the UIA-Skeptic is being far too uncharitable in her portrayal of the UIA-Backer, and so fails to offer a serious explanation of his phenomenological intuitions.

4 An alternative model of inner awareness

Faced with a phenomenological disagreement over the ubiquity of inner awareness, UIA-Backers and UIA-Skeptics have each put forward a range of arguments designed to resolve the dispute. Having surveyed these arguments, it is clear that none of them has the dialectical purchase needed to break the phenomenological stalemate. In this section I attempt to break the stalemate by introducing an alternative model of inner awareness. The first sub-section makes a proposal about the place of inner awareness in our phenomenology. The second sub-section addresses three potential objections to this proposal. The third sub-section suggests that this proposal offers a compromise position that accommodates some of the key claims made by each camp, and shows how it is equipped to offer a credible and charitable explanation of why the entrenched camps get their own phenomenology wrong.

4.1 The Affordance Model

If we wish to give a rich and accurate description of our phenomenology, we need to have the notion of affordances in our conceptual toolbox. When we perceive the world we are not merely passive spectators but rather active participants. Our potential to engage with our environment figures in our perceptual experience. The ball is not just given to us as red and round, it is given to us as kickable. We don’t just experience the traffic light as green, we experience it as inviting acceleration. We don’t just perceive Justin Bieber’s face as babyish and self-satisfied, we perceive it as slappable. In all these cases, the object we perceive appears to afford a certain action—eating, kicking and slapping respectively. Our opportunity to perform these acts figures in our experience: there is a manifest phenomenological difference between just seeing the ball and seeing it as kickable.

Our phenomenology is coloured by apparent affordances.Footnote 24 As with any apparent property, the appearance of an affordance is doubly dissociable from the actual presence of that affordance. You can be in a position to perform an act without this opportunity being apparent to you: you can be in a position to kick a ball without experiencing it as kickable. Conversely, in a non-veridical experience of an affordance, an opportunity to act seems to be available to you when it is not: a ball that seems kickable might actually be made of lead. As with perceptual appearances, experiencing an affordance should not be conflated with judging there to be an opportunity for action. Believing that you can kick an object is one thing, but experiencing it as kickable is quite another. Merely attributing the belief to a subject would fail to capture how kickability figures in her phenomenology. This comes out when we consider the possibility of experiencing the ball as kickable whilst simultaneously judging it not to be. Affordances also shouldn’t be conflated with imaginings. You don’t have a perceptual experience of the ball plus an imaginative experience of yourself kicking the ball. Rather, the kickability of the ball figures immanently in your experience of the ball itself.Footnote 25

Our experience of affordances can vary depending on the skills we have acquired. For instance, we begin to experience the green traffic light as inviting acceleration only after acquiring the ability to drive.Footnote 26 By contrast, affordances of grasping are often thought to figure in the perceptual experience of neonates. Our experience of affordances can also vary depending on the extent to which our environment solicits us to act (see Siegel 2014). Perhaps a collection of balls before you each seem kickable, but one particularly well-placed ball calls out to be kicked, colouring your experience in a way that the other balls do not.

Armed with the concept of affordances, we can offer a novel account of how inner awareness figures in our ordinary non-introspective experiences. Introspection is an action. All conscious states—or at least all ordinary conscious states of normal adult humans—are introspectable. This is a claim that both UIA-Backers and UIA-Skeptics seem to be able to get behind (see especially Thomasson 2005; Kriegel 2009a). My suggestion is that this ever-present potential for introspection actually figures in our experience. Your capacity to gain inner awareness of your concurrent conscious state colours what it is like to be in that state for you. Although our outer awareness of the world is not generally accompanied by an inner awareness of that very state, it is accompanied by an awareness of the opportunity for introspection. In other words, an affordance of introspectability is a ubiquitous feature of our phenomenology.

Thomasson comes close to this proposal when she suggests that ‘…it is a continuous part of our experience that we are immediately able to report on such experiences…’ (2006, p. 7). Unlike Thomasson though, my proposal concerns the potential for introspection rather than the potential to report on one’s experience. I am also not committed to Thomasson’s theory of how introspection and phenomenological reports work. In fact, this ‘Affordance Model’ can be combined with whatever is your preferred theory of introspection. So long as introspection is an act, we can experience an affordance to introspect, regardless of the details of what this act involves.Footnote 27 The Affordance Model is also consistent with introspection being a bundle of inter-related cognitive capacities rather than a unitary skill. If this were the case, we should expect a collection of subtly different affordances corresponding to the different cognitive activities.

Presumably infants and non-human animals cannot introspect. Abnormal humans, such as blindsighters, might be attributed unintrospectable conscious states. In normal humans the capacity for introspection might go ‘offline’ during abnormal states of consciousness such as dreaming. In all of these cases, it is unlikely that the subject’s experience is characterised by an affordance of introspectability. The Affordance Model does not make a universal generalisation about conscious states that would include such atypical experiences. It does, however, seek to make a generalisation about all ordinary experiences of normal adult humans. The ordinary experiences of normal adult humans are introspectable, and the introspectability of those experiences is phenomenologically manifest to the subject.Footnote 28

4.2 Objections and replies

I will now consider three potential objections to the Affordance Model and argue that they can each be avoided given appropriate clarification of the proposal. The first objection is that affordances correspond to potential bodily actions. When Justin Bieber’s face affords slapping, for instance, the phenomenology of this experience is bound up with a specific possible movement of one’s arm. But since there is no bodily action involved in introspection, there can be no affordance of introspectability. Against this objection I would reply that there are many cases of affordances for mental as opposed to bodily actions: a loud noise can afford attention, a lecture can afford concentration, and a statement can afford contemplation. Affordances of introspection are members of a larger group of cognitive affordances. A critic might respond that these cases cannot properly be described as ‘affordances’. However, the notion of cognitive affordances is not without precedent in the literature (e.g. Scarantino 2003, p. 960). And even if the critic insists that affordances must involve bodily actions, at this point I think we would have a merely terminological dispute. If our capacities to introspect, attend, concentrate and contemplate can colour our phenomenology even when we are not deploying those capacities, then the phenomenological features in question are affordances in every way that matters to me. If there are technical reasons to regard them as features analogous to affordances rather than as affordances-proper, the real content of my proposal would be unaffected.

The second objection concerns the sophistication that an affordance of introspectability would need to have. To be aware of our capacity to introspect, we would need to be aware of ourselves as agents with the ability to reflect on our experience. But in ordinary experience we are not aware of ourselves, or at least not aware of ourselves in any sophisticated way. Therefore in ordinary experience we are not aware of our capacity to introspect. This objection rests on an excessively intellectualised understanding of affordances. The ball can seem kickable without you forming any sophisticated judgment about yourself as a potential kicker. In fact, it’s quite credible that it could seem kickable even to creatures with no concept of kicking i.e. no capacity to entertain propositions about kicking. The way that kickability contributes to our experience is relatively unsophisticated. By the same token, the way that introspectability contributes to our experience is also not that sophisticated. Perhaps experiencing affordances requires us to experience ourselves as agents—as entities that can deploy their abilities—but I don’t see any reason to regard this as too sophisticated for ordinary non-introspective consciousness.Footnote 29

The third and final objection goes a little deeper but can still be overcome. If an act appears to be afforded to us, there must be something we are aware of which appears to afford that action. When kicking is afforded, for example, there must be a specific object that seems kickable to us. We never have a free-floating sense of kickability detached from any particular apparent object. What is it, then, that affords introspection? Here the Affordance Model seems to face a dilemma. One option is to say that it is something in the world that affords introspection. But the difficulty here is that external objects are not credibly introspectable. You cannot, for instance, introspect a red ball. On this horn of the dilemma, the Affordance Model is committed to an untenable view of introspection. The other option is to say that the thing that affords introspection is your conscious state. You cannot introspect a red ball, but you can introspect your experience of the red ball. But the difficulty here is that experiencing an affordance of introspectability would then presuppose an awareness of the state to be introspected. Consequently, if all our experiences afford introspection then we must be aware of all our experiences. On this horn of the dilemma, the Affordance Model thus collapses into UIA.

The dilemma trades on the following phenomenological principle: if an action φ appears to be afforded then there must be some apparent object x that appears to afford having φ done to it. I will seek to undermine this principle, thus allowing the Affordance Model to avoid the dilemma. The easiest way to find counter-examples to this principle is to consider acts that, unlike kicking or slapping, are not directed at an object. Dancing, for example, is not something we do to an object (Siegel 2014). Accordingly, when dancing appears to be afforded there is no object that appears to afford having dancing done to it. When you experience an affordance to dance in a nightclub, it is the situation—the music, the lights, the right degree of intoxication—that presents an opportunity for dancing. My suggestion is that introspection is like dancing in this respect. We can be aware of the opportunity to introspect in our current situation without having to be aware of any object as a thing to be introspected. Unlike with dancing, every ordinary situation presents an opportunity for introspection which is why the affordance of introspectability is a ubiquitous feature of our phenomenology.

Here the critic might respond that introspection is not relevantly analogous to dancing. Dancing is a counter-example to the original phenomenological principle because dancing is not an action directed toward an object. Introspection, however, is directed toward an object: specifically, one’s concurrent experience. As such, we should expect affordances of introspectability to have the same phenomenological structure as affordances of other object-directed actions. In other words, the critic can retreat to the following qualified version of the phenomenological principle: for all and only object-directed actions, if an action φ appears to be afforded then there must be some apparent object x that appears to afford having φ done to it. Since introspection is indeed an object-directed action, this qualified principle suffices to underwrite the dilemma for the Affordance Model.

My response to this objection is that even the qualified phenomenological principle doesn’t hold. Consider the act of searching for shelter. This is clearly an object-directed action: it is aimed toward the shelter. Presumably there are situations in which this action is afforded, but it is implausible that being aware of this affordance requires being aware of the object that is to be searched for. After all, a subject can search for shelter only if she is yet to find it, but can be aware of the shelter only once it has been found.Footnote 30 I suggest that affordances of introspection are analogous to affordances of shelter-searching. In both cases, the subject is aware of the opportunity to perform an object-directed action without being aware of the object in question. And in both cases, the subject only becomes aware of the object in question if she successfully performs the afforded act. The lesson we learn from the shelter-searching case is that if an action reveals an object to the subject, then we should not expect experiences of an affordance to perform that act to be characterised by an awareness of the object to be revealed. Introspection is just such an action: performing it reveals our own experience to us. As such, we should not expect the experience of introspectability to be characterised by a prior awareness of the conscious state to be introspected.

4.3 The dialectical significance of the Affordance Model

Ultimately the Affordance Model is answerable to your phenomenological reflection. If careful investigation suggests to you that this account accurately describes your experience, then you won’t need any theoretical arguments to convince you of its truth. If no amount of investigation makes this description plausible, then the theoretical arguments I offer may not persuade you. Nevertheless, it is worth considering how the Affordance Model can weigh in on the debate between UIA-Backers and UIA-Skeptics.

One thing to note is that the Affordance Model qualifies as a UIA-Skeptic position: it denies that all experiences of normal adult humans are characterised by an inner awareness of that very experience. That said, standard forms of UIA-Skepticism (i.e. all sceptical positions other than the Affordance Model) do not posit a ubiquitous affordance of introspectability. In fact, by making such a posit the Affordance Model reflects something of the spirit of the UIA-Backers. Overall, the Affordance Model is best regarded as a compromise position that finds a middle ground between the UIA-Backers and the standard UIA-Skeptics. It claims that both sides are partly right and partly wrong, and that the truth lies somewhere between them. I hope to show that by adopting this reconciliatory posture, the Affordance Model can gain far greater dialectical traction than either of the two entrenched camps.

What exactly does the Affordance Model say about the merits and failings of the two entrenched camps? It says that the UIA-Backer is right to deny that the phenomenology of non-introspective experiences is exhausted by our outer awareness, but wrong to say that those experiences are characterised by an occurrent inner awareness. Occurrent inner awareness is in fact limited to episodes of introspection. On the other hand, the standard UIA-Skeptic is right to deny that non-introspective experience is characterised by occurrent inner awareness, but wrong to say that the phenomenology of non-introspective experience is exhausted by outer awareness, with inner awareness making no contribution to our experience. Although inner awareness is not always present, its potential to be brought into presence is in fact a ubiquitous feature of experience.

Now, since the Affordance Model says that both of the entrenched camps are partly mistaken, it owes us an explanation of why these mistakes are made. My suggestion is that both camps misdescribe their phenomenology because they lack the concepts needed to provide a fully accurate description. When trying to describe our experience, we are somewhat restricted by the phenomenological concepts with which we are familiar. One concept that neither camp has at its disposal is that of affordances of introspectability. Without this concept, it is easy for one’s phenomenological judgments to be led astray. Once the UIA-Skeptic has correctly recognised that non-introspective experiences do not involve occurrent inner awareness it is natural, though mistaken, for them to infer that our capacity for inner awareness can have no influence on what it’s like to undergo such experiences. Similarly, once the UIA-Backer has correctly recognised that our capacity for inner awareness does influence what it’s like to undergo non-introspective experiences it is natural, and again mistaken, to infer that inner awareness is occurrently present in such experiences. Neither camp is in a position to frame the possibility that our capacity for inner awareness contributes to our phenomenology by presenting an affordance for us to deploy that capacity, rather than by actually being deployed. The phenomenological descriptions offered by both camps are imperfect approximations of the truth: they reflect people’s best effort to describe their experience with the limited concepts at their disposal. Of course, by introducing the Affordance Model I hope to correct this mistake.

Throughout the paper I have contended that the arguments presented by both UIA-Backers and standard UIA-Skeptics lack genuine dialectical force. In what ways does the Affordance Model improve on the entrenched positions in this regard? One of the main objections I’ve raised is that each camp fails to take the phenomenological intuitions of their opponents seriously enough. The Affordance Model has the advantage of taking the intuitions of both sides very seriously. Although it says that the UIA-Backers are wrong, it regards them as closer to the truth than the standard UIA-Skeptic regards them. Similarly, it says that the standard UIA-Skeptics are wrong, but regards them as closer to the truth than the UIA-Backer regards them. Like any compromise proposal, the Affordance Model manages to avoid an excessively uncharitable view of either camp in the debate.

A further objection I’ve raised is that neither of the entrenched camps has successfully explained why their opponents would get their own phenomenology wrong. Specifically, I argued in Sect. 3 that none of the via negativa arguments offered satisfy the following two rules: I) not being applicable against both camps with equal force and; II) not attributing the opponent a kind of mistake that she is not otherwise disposed to make. The Affordance Model holds that both camps partly misdescribe their phenomenology because they lack the concept of affordances of introspectability. This proposal satisfies the first rule because a critic cannot respond that it is actually proponents of the Affordance Model who have been misled by their more limited conceptual repertoire. The Affordance Model adds a new concept into the existing mix, so it cannot be the case that it is proponents of the entrenched views that actually have the richer conceptual repertoire. The Affordance Model also satisfies the second rule. When we lack the concepts needed to fully describe a phenomenon, we are generally vulnerable to the mistake of partly misdescribing that phenomenon. Specifically, we are all disposed to make the mistake of offering imperfect approximations of the truth using the concepts at our disposal. Consequently, the Affordance Model does not attribute either camp a kind of error that they are not otherwise disposed to make. In fact, it charitably suggests that the mistakes made by all parties are relatively innocent. Overall then, the Affordance Model is in a far better position to explain the mistakes of its opponents then either of the entrenched camps is.Footnote 31

Does this explanation of where the entrenched camps have gone wrong commit me to the prediction that on reading this paper they will immediately see the error of their ways and become card-carrying supporters of the Affordance Model? I am not optimistic about the prospects of this ambitious prediction, but fortunately the Affordance Model is not committed to such a forecast. Sometimes people do not abandon their mistaken judgements even when the source of their mistake is correctly identified and a superior alternative position is presented to them. If proponents of the standard views do not abandon their positions when presented with the Affordance Model, this would be quite consistent with the model having diagnosed their mistakes accurately. Perhaps the Affordance Model could be asked to provide a further explanation here—an account not just of why people make their initial mistaken judgement but of why they retain it after it has been undermined. Such a further explanation should not be hard to come by. Perhaps proponents of the standard views are too entrenched in their mistaken ways of thinking to recognise the value of the alternative with which they are presented. Philosophy is replete with cases of this kind. Or perhaps they don’t yet have a sufficient understanding of the alternative view to see its truth. As we have already seen, it is difficult to capture what an affordance of introspectability would be like, so dissenters could easily be looking for the wrong thing in their experience.

The question of whether inner awareness is ubiquitous has led to a recalcitrant phenomenological disagreement. Both sides of the dispute have tried to break this stalemate by deploying a number of arguments against their opponents, but we have seen that none of these arguments has any real dialectical purchase. Transcending these entrenched positions, the Affordance Model offers a fresh account of the relationship between our capacity for inner awareness and the phenomenology of non-introspective experience. At the very least this model offers a new avenue of enquiry. Beyond that though, I hope to have shown that it has significant dialectical advantages over its competitors. It offers a compromise position that respects the driving phenomenological insights of both camps, and provides a charitable explanation of where each side has been led astray.
