 However, Russell’s idea that the propositional contribution of the verb binds the constituents together (in different ways in the case of our pair of sentences) is hard to understand. In the next to last quotation from Russell above, he suggests that the proposition expressed by ‘A differs from B’, whose constituents are A, difference and B, is held together by difference actually obtaining between A and B. If we call difference a relation, the proposition would consist of A standing in the relation of difference to B. Russell makes a number of remarks that suggest that this is his view. But it would seem that this cannot be correct. Intuitively, A standing in the relation of difference to B is what makes the proposition that A differs from B true. It is not the proposition itself. For if it were, it would seem that if A doesn’t stand in the difference relation to B, then there is no (false) proposition to the effect that A differs from B. And quite generally, for the same reason it would appear that there are no false propositions. Perhaps Russell meant that propositional contributions of verbs hold propositional constituents together in some other manner. But it certainly is not clear what that manner would be. Or perhaps he held a view similar to Zalta’s discussed above.
