Illusions of Sense in the Tractatus : Wittgenstein and Imaginative Understanding

Certain expositors of the Tractatus have tried to make sense of Wittegnstein’s curious revocation of its propositions by suggesting that although they lack content, they nonetheless express (“show,” but do not say) some ineffable truths about reality. Such a view Cora Dimaond labels “chickening out.” I attempt to diagnose the lingering attraction of the ‘chicken’ (in this case an attraction to an illusion of sense) by condsidering a (false) parallel with the case of perceptual illusion. To this end, I make a brief excursion into the work of Gareth Evans in order to draw out what the parallel would look like and more specifically how the chicken might be tempted to think that there is indeed such a parallel. In this way, I hope to better ‘understand’ the chicken and her seduction, and in the process make a plea for not “chickening out.” I then turn to a positive consideration of how we should in fact read this work. In particular, I consider Diamond’s idea that the Tractatus requires an “imaginative understanding” of its reader, an ability to ‘think’ oneself into certain philosophical illusions of sense in order to dismantle them from within. I explore exactly what such an imagination involves. In particular, I suggest that it presupposes a kind of ‘metaphysical’ thesis of its own about the nature of human beings and their innermost tendencies, a position, I argue, that Wittegnstein held.
