 Stebbing’s assertion of what she knows is hardly likely to be seen by anyone other than a committed Moorean as a knockdown argument against any form of solipsism. She goes on to accuse Wittgenstein, and the logical positivists who were influenced by him, of confusing “direct experience” and “content”, but no evidence is offered for saddling Wittgenstein with the views she claims he had. However, in the last quarter of the paper, she makes clear that what is really at issue, in her view, is a conflict between two different conceptions of analysis, which she calls “directional analysis” and “postulational analysis”. Directional analysis is the form of analysis that she had attempted to defend in her 1932 paper. Postulational analysis is what is used “in the construction of a deductive system” (1933a: 80). Axioms are stipulated and everything else in the system is derived by the rules of inference.
