The concept horse with no name

Abstract

In this paper I argue that Frege’s concept horse paradox is not easily avoided. I do so without appealing to Wright’s Reference Principle. I then use this result to show that Hale and Wright’s recent attempts to avoid this paradox by rejecting or otherwise defanging the Reference Principle are unsuccessful.

Notes

  1. 1.

    The locus classicus of this paradox is Frege’s ‘On concept and object’ (1892), but he also discusses it elsewhere, most notably in ‘Comments on sense and reference’ (1891–1895).

  2. 2.

    In fact, this is just one half of what Wright (1998, p. 73) calls ‘the Reference Principle’; the other is the principle that co-referring expressions are intersubstitutable salva veritate in extensional contexts. For my purposes, however, it will suffice to focus solely on the half of the Reference Principle presented above.

  3. 3.

    The role of the Reference Principle in Frege’s thinking about the concept horse paradox is most visible in his (1892, p. 189).

  4. 4.

    See for example Frege (1923, p. 393).

  5. 5.

    See Frege (1893, Sect. 32) and Dummett (1981b, pp. 249–251). If we prefer, we could think of the sense of a sentence as its assertability-condition.

  6. 6.

    Indeed, it seems plausible to suggest that ‘I’ and ‘me’ have exactly the same sense; the difference between these words would then be a product of the particular grammar of English. If that is right, then ‘I’ and ‘me’ are trivially intersubstitutable at the level of sense.

  7. 7.

    See also Frege (1892, p. 189).

  8. 8.

    From now on I will usually leave this qualification tacit.

  9. 9.

    See for example Frege (1892, p. 189, 1891–1895, p. 175).

  10. 10.

    At least, (4) is obviously true when our metalangauge is (an extension of) our object-language. In this paper I will ignore the case where the metalanguage is not (an extension of) the object-language; however, I believe that we could extend my argument to cover this case if we helped ourselves to an appropriate notion of translation.

  11. 11.

    I am here making the standard assumption that predicates are objects. I suspect that this assumption is false, but one thing at a time!

  12. 12.

    It is, however, grammatical to write ‘“\(\xi\) is a horse” refers to horses’, and it is well known that plurals in English at least sometimes play the role of predicates. Nonetheless, it is still not clear how to understand this sentence, nor is it clear that ‘horses’ is playing the role of a predicate in this particular sentence.

  13. 13.

    Dudman (1976, Sect. II), Wiggins (1984, pp. 316–317), Gaskin (1995, 164–166) and Wright (1998, pp. 77–81) all criticise Dummett’s proposal.

  14. 14.

    In fact, this claim is a little premature, and will not be fully justified until Sect. 6.

  15. 15.

    In order to explain fully how such a higher-order definite description operator works, we would have to say something about how to talk about identity in relation to properties. This is something that I will discuss in Sect. 6.

  16. 16.

    Compare Wright (1998, p. 79).

  17. 17.

    Hale (2013b, p. 142) recommends that we take ‘\(\square \forall x (\phi x \leftrightarrow \psi x)\)’ as a second-level analogue of identity; however, he also thinks that we can refer to properties with singular terms and so can also use ‘\(\xi =\zeta\)’ in relation to properties.

  18. 18.

    I am here assuming that if any property were an object, then every property would be an object. If you do not want to make this assumption, then you should weaken the requirement that \(\fallingdotseq\) be reflexive as follows: for any \(F\), if \(F\) bears \(\fallingdotseq\) to anything then it must bear \(\fallingdotseq\) to itself. For ease of expression I will leave this complication out of the main text.

  19. 19.

    They (2012, Sects. IV–VI) do ask whether there is something deeper that might motivate us to accept the Reference Principle; however, they then set about showing that there is not.

  20. 20.

    In fact, Wright (1998, Sect. VII) argues that the Reference Principle itself demands that we distinguish between reference and ascription. I will not discuss that argument here.

  21. 21.

    The idea that predicates ascribe rather than refer to properties is further developed by Liebesman in his (forthcoming).

  22. 22.

    Hale presents the same solution to the concept horse paradox in his (2013a, Sects. 1.7–1.10). He further explains the idea that terms refer to properties only 'derivatively' in Hale and Wright (2012, Sect. VII).

  23. 23.

    See, for example, Oliver (2005, p. 177), Noonan (2006, p. 167), Dolby (2009, p. 286), Textor (2010, p. 130), MacBride (2011, p. 299) and Trueman (2012, p. 98).

  24. 24.

    Perhaps we could amicably agree to call Hale’s objects ‘bobjects’ and my ones ‘robjects’.

  25. 25.

    See Frege (1892, p. 189, 1891–1895, p. 175), Geach (1976, pp. 57–58) and Dummett (1981a, pp. 177–178).

  26. 26.

    My predicament is exactly the same as the one in which Wittgenstein found himself at the end of the Tractatus (6.54). This should come as no surprise. As Geach (1976) convincingly argues, Wittgenstein’s saying/showing distinction has its roots in his reflections on the concept horse paradox.

  27. 27.

    See Button (2010, Sect. IV) for a similar line of thought.
