ABSTRACT
Ludwig Wittgenstein died on 29 April 1951. He had been working hard for many years on a major manuscript that would present his philosophical achievements, and although he never managed to bring this project to conclusion, his literary executors did not have to make many editorial decisions before the manuscript to be published. Philosophical Investigations was published in 1953 in an edition featuring an English translation by G. E. M Anscombe alongside the German original. In Norman Malcolm's view of Wittgenstein as an ordinary language philosopher that explains the methodological assumptions that occasionally surface in Malcolm's review of Philosophical Investigations. In his review of Philosophical Investigations Strawson had also focused on criteria. According to him the notion of criteria had wrongly led Wittgenstein to advance the Reductio Argument. The difference between the strengths of the Reductio Argument and the External Argument was paralleled by a difference in strength between two theses which Strawson had taken Wittgenstein to oscillate between.
