Listening back to the discussion Pete and I had, as well as my previous post on this stuff, and something occurred to me. There really are two different ways of thinking about the concept “unicorn”. One way is the way that I have been thinking about it ad that is as a regular natural kind term like ‘horse’, ‘tiger’, etc. Concepts like this, according to me, are best treated along the lines of a causal-historical account like the Kripkean inspired theory that Devitt produced. But there is another way of thinking about unicorn, one that thinks of it as like ‘bachelor’ rather than ‘tiger’. Terms like that are best treated in terms of a conceptual-role theory. So, it is the relations between the concept ‘bachelor’, ‘unmarried’, and ‘male’ that makes my thought that all bachelors are unmarried males true. If one thought about ‘unicorn’ like this, one might think that it is the conceptual relations between ‘unicorn’, ‘horse’, and ‘horn’ have that make it the case that when I am thinking about unicorns I am thinking about horned horses. That is, one might think of the concept ‘unicorn’ as being defined as ‘horse with a horn’. Now, it seems to me that we employ both kinds of representations in thought so then the question becomes one of which kind features in the content of higher-order thoughts. I claim that it is the former and not the latter and that that matters.
