 It is unclear to what degree Sibley, beyond seeking to establish that the application of aesthetic concepts is not condition-governed, seeks also to define the term ‘aesthetic’ in terms of their not being so. It is clearer, perhaps, that he does not succeed in defining the term this way, whatever his intentions. Aesthetic concepts are not alone in being non-condition-governed, as Sibley himself recognizes in comparing them with color concepts. But there is also no reason to think them alone in being non-condition-governed while also being reason-supportable, since moral concepts, to give one example, at least arguably also have both these features. Isolating the aesthetic requires something more than immediacy, as Kant saw. It requires something like the Kantian notion of disinterest, or at least something to play the role played by that notion in Kant’s theory.
