[215] into the great limits. I had two talks yesterday, when I had to speak in Princeton University---one with a logical positivist^a and one with a publisher of a book on logical positivism---and in both cases I discovered just that awareness of which l spoke last Thursday. The publisher says he is fascinated by the problems of symbolic logic and semantics and all that belongs to this realm, but he himself likes it equally with the chess play (he is a chess player, so am I), and from this point of view, we LIKE the logical movements of logical positivism. And the decisive thing is: to become aware of the fact that, AS THEY STAND NOW, they have no relevance, DIRECTLY, for encountering reality. They are abstracted from any reality. They speak about language and thought, but not about something which is GRASPED by language and thought. Now the other talk was with somebody who is especially interested in the scientific presuppositions (the logical and epistemological presuppositions of sciences) and worked closely together with Einstein^b for many years---and he has discovered that there is in the human mind a function which he calls intuition, into which he now puts religion, and which is not logical calculus. I think he will go beyond that one day. I told him: now you have two, one day you will have three, functions, and the third will be existential participation, which is more than intuition. But l wait--- it will come! [some laughter]. This means: reality makes itself felt as not exhausted by these preliminary discussions of ways to reality---of methods.
