Explicit references to Russell's ideas are numerous in theTractatus. I am less interested in discussing these than the themes which lie just beneath the surface of the text where, I suggest, Wittgenstein was engaged in either correcting or modifying a number of the epistemological and metaphysical views he had encountered in Russell's writings. Chief among these, of course, is the concept of a proposition, a topic which they approached in sharply different ways. But no less interesting are the topics of logical form, internal relations, belief, the Self, thecorrespondence between Realism and Solipsism, and even the mystical attitude towards the world.
R. E. Tully (Sat,) studied this question.
