Abstract

If I have been correct in my surmise that Weiss is no reductionist in the ordinary sense, then it is evident that he can offer no definition of mind in any ordinary or straightforward manner. The only way in which he could offer a definition would be, on the basis of the ontological reducibility of mind, by reference to Actuality of which it is asserted to be a function. But Weiss has not provided such a definition, nor is it easy to see how this omission could be rectified. For the proposition that mind is an expression of the self, the most obvious candidate for a definition, does not identify mind uniquely: there are expressions of the self which are not mental. Thus what is needed is a differentia, a characteristic distinguishing mind from all the other expressions of the self.
