So he returned to Cambridge to say so and began to do philosophy again or, as he said, if not to do philosophy then at least to teach philosophy. While his book made his influence ever greater, while his ideas were decisively influencing the Viennese Circle and in general all of the later developments of logical positivism, Wittgenstein felt more and more empty and dissatisfied. He viewed his own philosophy, he once said in class, the way Husserl had said that psychoanalysis should be viewed: as a sickness that confuses itself with the cure. That was what Husserl said about psychoanalysis, Wittgenstein said that time in class, and that is what I think of my own philosophy, expounded in the Tractatus. That is what Ludwig Wittgenstein would say about himself and about his ideas to his students at Cambridge in 1936, Tardewski tells me, which should at the very least be considered an example of what some people call intellectual courage and fidelity to the truth.
