 The idea that philosophy is not a doctrine, and hence should not be approached dogmatically, is one of the most important insights of the Tractatus. Yet, as early as 1931, Wittgenstein referred to his own early work as ‘dogmatic’ (“On Dogmatism” in VC, p. 182). Wittgenstein used this term to designate any conception which allows for a gap between question and answer, such that the answer to the question could be found at a later date. The complex edifice of the Tractatus is built on the assumption that the task of logical analysis was to discover the elementary propositions, whose form was not yet known. What marks the transition from early to later Wittgenstein can be summed up as the total rejection of dogmatism, i.e., as the working out of all the consequences of this rejection. The move from the realm of logic to that of the grammar of ordinary language as the center of the philosopher’s attention; from an emphasis on definition and analysis to ‘family resemblance’ and ‘language-games’; and from systematic philosophical writing to an aphoristic style—all have to do with this transition towards anti-dogmatism in its extreme. It is in the Philosophical Investigations that the working out of the transitions comes to culmination. Other writings of the same period, though, manifest the same anti-dogmatic stance, as it is applied, e.g., to the philosophy of mathematics or to philosophical psychology.
