 Wittgenstein, moreover, thinks it obvious that in the case of every proposition this process of analysis does terminate. The reason he supposes analysis cannot go on forever is that he conceives an unanalyzed proposition as deriving its sense from its analysis. As Tractatus 3.261 puts it: “Every defined sign signifies via those signs by which it is defined” (Cf. NB, 46; PT 3.20102). It follows that no proposition can have an infinite analysis, on pain of never acquiring a sense. So the process of analysis must terminate, and when it does so the product will be propositions devoid of incomplete symbols.
