Abstract
Before I come to Professor Anderson’s objections to the argument in question, I should like to clarify just a few points. The argument that I presented is taken immediately from Mortimer Adler’s presentation of it, so let us call it ‘Adler’s Argument,’ though in fact its origins go all the way back to Aristotle. My reading of Adler’s presentation of the argument was that he gave it in two different forms, one categorical, the other hypothetical. Both forms of the argument, of course, have effectively the same conclusion, which is, in the case of its categorical version, that “concepts are not physical beings” [proposition 3 for Professor Anderson] and, in the case of its hypothetical version, that “A concept is not an act of a bodily organ” [proposition 6 for Professor Anderson]. Now Adler concludes immediately from propositions 3/6 that “the power of conceptual thought is an immaterial power.” I argued in my original article that it was not obvious that this proposition was equivalent to propositions 3/6 and so I presented an additional argument to the bridge the gap [propositions a, b, c and d for Professor Anderson]. Let us call this ‘Casey’s Addendum.’.
