We have been talking about the relation of mathematics to its application. What we really want to get at is the relation of the role which an experiential proposition plays to the role which a mathematical proposition plays. For “mathematical propositions”, & one kind in particular, sounds like “experiential propositions”, i.e., suggests to us an entirely different use than the actual one. And we must understand that the meaning of a proposition lies in the use we make of it & that this is hidden from us only by the fact that certain associations are bound up with our sentences, an imagery which quietens our || any doubt as to whether what we say are only mere words.
     It has been said that a sentence has not only a meaning but also a soul: & we mustn't let ourselves be mislead by the appearance of such a soul. One could imagine a language without such souls; in fact our chemical symbolism is such a language.
     A language in which we would have to decode every sentence.
