What kind of truth can psychiatric experts know about their patients? Scientific theory can be learned from reading books, so why is that therapists need to talk to their patients? Why can't they simply point people to the most relevant papers? This excellent book explains Wittgenstein's therapeutic approach to language, with a particular focus on the way that classical psychiatry has failed to understand the relevance and importance of Wittgenstein's ideas. Highly recommended for anyone involved in psychiatry or psychotherapy, or for students of the philosophy of mind.
