Abstract

Wittgenstein writes in the preface to the Philosophical Investigations: ‘I should not like my writing to spare other people the trouble of thinking. But if possible, to stimulate someone to thoughts of his own.’ In the following I argue that this indicates something essential about Wittgenstein’s approach. In order to remain true to his conception of philosophy without theses, he could not, for example, aim to instruct his reader about about grammar or put forward prescriptions about grammar, logic or language use. Thus, there is an essential connection between the aim of stimulating the reader to thoughts of their own, and philosophizing without theses. In order to clarify this I will discuss both Wittgenstein’s early and later account of philosophy without theses, his later rejection of philosophical foundations and the hierarchical organization of philosophy, such as assumed in his early philosophy, the notion of agreement in Wittgenstein’s later philosophy, and certain remarks from the Nachlass on the composition of his book, eventually published as the Philosophical Investigations.
