Abstract

The paper argues, in a nutshell, that Wittgenstein’s reconsideration, after Ramsey’s review, of the Tractatus provides the rationale for the methodological reflections from the former’s manuscripts, which are less sceptical than Schlick’s, on the viability of a phenomenological philosophy. The argument proceeds like this. Section 1 exposes a charge against a Tractarian account of logical syntax: for Ramsey, early Wittgenstein holds unjustifiably that any proposition taken to exhibit logical impossibility, like the impossibility of a fleck of two colours, is analysable into formal contradiction. Section 2 explores ways in which Ramsey’s charge is taken on board by Wittgenstein’s 1929 “Some Remarks on Logical Form”, while bringing forth the view that propositions like “This is of two colours” cannot be analysed into formal contradiction. Section 3 reconstructs a mirror image of early Wittgenstein’s approach to colour-exclusion, from Schlick’s claim that propositions like “This cannot be of two colours” exhibit logical necessity and amount to formal tautologies. Section 4 isolates two responses two Schlick’s approach to colour-exclusion, suggesting that it is not more viable than early Wittgenstein’s. Section 5 assesses the rationale of Wittgenstein’s reflections on phenomenology, as informed by his approaches to colour-exclusion from early onwards.
