There can never be surprises in logic. - Ludwig Wittgenstein

I should not like my writing to spare other people the trouble of thinking. But, if possible, to stimulate someone to thoughts of his own.

Don't say: “They must have something in common, or they would not be called ‘games’" but look and see whether there is anything common to all. For if you look at them, you won't see something that is common to all, but similarities, affinities, and a whole series of them at that. To repeat: don't think, but look!

To be sure, I can imagine what Heidegger means by being [Sein] and anxiety [Angst]. Man feels the urge to run up against the limits of language. Think for example of the astonishment that anything at all exists. This astonishment cannot be expressed in the form of a question, and there is no answer whatsoever. Anything we might say is a priori bound to be mere nonsense. Nevertheless we do run up against the limits of language.
