2 Frank Sibley claims that ‘we need, but are never given’ in Geach's article a ‘definition or elucidation’ of the terms ‘logically predicative’ and ‘logically attributive’ (‘Adjectives, Predicative and Attributive’, in Sibley, , Approach to Aesthetics: Collected Papers on Philosophical Aesthetics, edited by Benson, John, Redfern, Betty, and Cox, Jeremy Roxbee (Oxford: Clarendon Press, 2001, 156)CrossRefGoogle Scholar. We take the quoted passage to be intended as just such a definition or elucidation. We also reject, for reasons that will become apparent in what follows, Sibley's view that the arguments that Geach provides for holding that certain adjectives are attributive imply several different ‘tests’ of attributivity, each yielding different results.
