This is a collection of the key articles written by renowned Wittgenstein scholar, G.P. Baker, on Wittgenstein's later philosophy, published posthumously. Following Baker's death in 2002, the volume has been edited by collaborator and partner, Katherine Morris. Contains articles previously only available in other languages, and one previously unpublished paper. Completely distinct from the widely-known work Baker did with P.M.S. Hacker in the "Analytical Commentary on the Philosophical Investigations" (Blackwell Publishing, 1980-1996).
