Logic and Assertion

Michael Potter (Cambridge University)

Michael Potter will give his inaugural lecture as Professor of Logic.

On 9th October 1913 Ludwig Wittgenstein dictated a typescript, part of what are now known as the Notes on Logic, in the presence of his supervisor, Bertrand Russell. In that typescript Wittgenstein says that `assertion is merely psychological’? Why does he say it, is it true, and what consequences does it have for our understanding of logic?

This lecture is open to the public.
