Abstract

Wittgenstein refers to psychophysical parallelism in this apparently prejudiced way in paragraph 611 of Zettel , in the course of a rather remarkable passage. It begins at 605 with the claim that ‘One of the most dangerous ideas for a philosopher is, oddly enough, that we think with our heads or in our heads’. Subsequent sections develop this remark in a way that demonstrates Wittgenstein's rejection of the view that thinking is any sort of process in the head, whether a physiological process or a matter of the operations of ‘a nebulous mental entity’. Indeed he appears to consider that these ontologically opposed alternatives have a common source, in that they both derive from the mistaken view that there must be a mediating process between psychological phenomena such as my present remembering and my experience of the remembered event . If we find no suitable mediating physiological process, we are easily led to assume that there must be a process of a rather different sort, and hence we are led to believe in a ‘nebulous mental entity’. But this whole line of thought in fact depends on a ‘primitive interpretation of our concepts’, an interpretation which we uncritically made at the stage at which we assumed that there must be a process of some sort mediating between the phenomena. We are reminded of Wittgenstein's earlier remarks in Philosophical Investigations , I, 308
