Abstract

Rom Harré has recently proposed that there is a difference between the driving force behind the early and the later Wittgenstein. According to Harré, in the early work, the major inspiration came from science, while, in the later, it came from religion. I show that only Harré’s first proposal is fully justified. In section one of my paper, I examine the picture theory, the theory of truth-functions, the meaning of propositions, and Tractatus §6.3. In section two, about the Philosophical Investigations, I show that Harré is misleading. In a first step, I argue that science plays the same role in this later work as in the Tractatus, namely the role of source of inspiration. In a second step, I show that science plays also the role of a contrast against which the rich world of meaning can be discerned. I examine this contrastive role not only as regards religion, but also as regards psychology, and as regards the repercussions of Wittgenstein’s later work on science-studies. My final proposal is that the distinction between science as source of inspiration and science as a contrast goes beyond Wittgenstein: it characterises much twentieth century philosophical work in this area.
