The project of considering health in an enacted framework may appear far-fetched considering the way health is standardly addressed in medical science. Health, in the context of medical science, and, also, in most cases of medical practice, is focused upon only indirectly by way of the absence of disease(s) or other maladies, such as injuries, inborn defects or mental disorders. And diseases are biological phenomena rather than belonging to the person-related sphere of cognition, perception and action. From the biomedical perspective, health is not something we do, it is rather something we have or do not have depending upon the biological state or our bodies.
An influential and still standing version of the biomedical definition of (ill)health via disease was presented by Christopher Boorse in the 1970s (Boorse 1977, 1997). According to Boorse, a biological organism (human or other) is healthy if it is not afflicted by any diseases. The concept of disease is defined by Boorse a state of an organ (or organ system) which interferes with or prevents the normal functioning of the organ in question. Organs and their parts (tissues, cells) function normally, according to Boorse, when they contribute to the survival and reproduction of the organism in a statistically standard manner. Diseases may be thought of as processes rather than states – say when a virus infects an organism – but the key issue is that at some point in the invading process organ(s) of the organism reach(es) a diseased state making the bearer unhealthy (hopefully in this case only temporarily, but in some cases leading to chronic disease). Lennart Nordenfelt sums up the perspective and key points of such a biomedical health concept nicely:
Humans have a number of specific characteristics in terms of both structure and function. We have some idea of how these characteristics have contributed to the survival of individuals and the species as a whole. Through this knowledge we can picture a pattern for the life of a surviving individual. Through this vision we have laid the foundation for a biologically oriented theory of health and illness. A healthy human being, such a theory says, functions according to the pattern which is typical for the species man. A human being is unhealthy, on the other hand, if one or more of her functions deviates subnormally from this pattern (Nordenfelt 2000: 77).
There are many ways of arguing and showing that the biomedical concept of health is insufficient, at least in the case of human beings. The focus on disease is certainly not incorrect – diseases are obviously main causes of illness – but the idea that all there is to say about health could be said by way of focusing upon the functionality of the biological organism is questionable. Humans (and perhaps some other animals, too) are not only biological organisms, they are also persons who may fall ill and suffer as the consequence of other things than diseases, and who may in some cases be healthy in spite of having minor diseases if these do not bring about any sufferings.
As a matter of fact, Boorse acknowledges himself that a health theory based on medical science will always have to face the dilemmas of medical practice, including ill persons, by developing what he refers to as “disease-plus” concepts (Boorse 1997: 100). I may be currently healthy in Sweden but not in the USA, depending upon how the upper limit of a “too high” blood pressure is negotiated, and this in turn depends upon medical risk evaluations made by doctors as well as lobbying from pharmaceutical companies. However, it could be argued that health is normative in a deeper sense than being influenced by the way individual physicians, health care authorities and lobbyists define subnormal bodily functions, since persons have goals that extend, and in some cases even run counter to, their survival and reproduction (Canguilhem 1991). Humans want to achieve many more things in life than simply surviving and having offspring, and these goals are possibly important to understand the difference between health and illness.
Lennart Nordenfelt, cited above, is probably the most well-known philosopher developing such a multi-goal holistic concept of health in contrast to the biomedical version defended by Boorse and other naturalists following in his footsteps (Kingma 2014). Holistic theories consider “the human being as a whole”, the individual person, to be the healthy or not healthy in contrast to his or her biological body (Nordenfelt 1987: 12). According to Nordenfelt: “A is healthy if, and only if, A is able, given standard circumstances in his environment, to fulfill those goals which are necessary and jointly sufficient for his minimal happiness” (1987: 79); and minimal happiness is considered by Nordenfelt to be an emotional state in which the individual believes that his basic vital goals in life have been achieved (1987: 91). Nordenfelt thinks we all share some vital goals having to do with basic human needs, but he also provides space for personal variation depending upon life style preferences and the world view of each individual. One of the major reasons for being unable to reach one’s vital goals is certainly various forms of diseases afflicting the body, but such diseases do not render the individual unhealthy by themselves, but only by influencing the person’s capability to act.
Does Nordenfelt’s theory make health into an enacted concept? I would say no, since the things that make a person healthy or unhealthy are not actions in themselves but (dis)abilities to perform actions. Health is not an activity, and, correspondingly, illness is not a defective form of activity, they are rather things making successful actions possible or not possible. If a person is able to carry out the actions necessary to attain minimal happiness or not, is dependent not only upon the abilities of the person, but also upon the opportunities provided by the environment, a factor which Nordenfelt takes into account by specifying “standard circumstances” in his definition (1987: 79). In later works, Nordenfelt sides with the phrase “accepted circumstances,” as an alternative for “standard circumstances” (Nordenfelt 2000: 73), but the idea is still the same: to exclude situations in which the individual gets access to non-standard forms of assistance or is deprived of standard opportunities to do everyday things that matter to him in life. Thus, in Nordenfelt’s understanding, it is perfectly possible for an individual to be healthy but very unhappy – because of non-standard circumstances such as extreme poverty or war – or ill but happy – because of vital life goals being realized by fortunate circumstances involving help provided by others.
Note that also the thing that health makes possible – happiness – is not an activity in Nordenfelt’s understanding, but rather an end state of actions and other natural happenings that give rise to a belief held by the individual: that things in life are roughly the way I want them to be. The actions of a person are, so to say, the things that make a happy life possible, but happiness itself is a state of belief (Nordenfelt 2000: 86). Nordenfelt calls such a state of equilibrium, between a person’s wishes and the belief that they have been realized, an emotion, but this merely indicates that the person will standardly feel good about her situation during some periods of the time interval of being happy, not that she necessarily does so all, or even most of, the time when being happy (2000: 88). Nordenfelt clearly defends a cognitive and dispositional theory of emotion, similar to the one developed and defended by Martha Nussbaum (2001). I will return to the issue of how to consider the felt quality of emotions in presenting the main thoughts of phenomenology in relationship to enactivism below (Colombetti 2014).
Actions are defined by Nordenfelt as movements of the body carried out in attempts to reach goals aspired by the acting person more or less consciously. You may have to ask the person if the waiving of her hand is carried out in order to hit a fly or to greet you, but the action in question has to be visible for you in order to count as an action. It is debatable whether this is a third-person or rather a second-person perspective. A third-person perspective denotes a scientifically neutral study of the acting subject (turning him into an object), whereas a second-person perspective would rather make him a fellow subject in the everyday world (what phenomenologists refer to as a “life world”). In both cases, however, the acting person would be approached from outside-in rather than from inside-out (the first-person perspective of the phenomenologist). An important question, which I will return to below, is if enactivism has fully adopted the significance of the phenomenological first-person perspective in stressing the inside-out approach.
Experiences of suffering or well-being play an indirect role in Nordenfelt’s health theory, as being typically experienced in illness versus health, but they do not define health status as such, only the ability to act and the setting of vital goals do. Phenomenological theories of health and illness view things differently; from a phenomenological point of view the embodied and worldly embedded experiences of a person would be the primary focus in determining whether she is healthy or not (Svenaeus 2019). A phenomenologist will start out in the first-person perspective-manner when it comes to analyzing health and illness and doing so will have consequences for our views on what constitutes actions and activities as ways of being in the world in the first place (Aho and Aho 2008; Carel 2016).
