A tautology's truth is certain, a proposition's possible, a contradiction's impossible.

It is all one to me whether or not the typical western scientist understands or appreciates my work, since he will not in any case understand the spirit in which I write. Our civilization is characterized by the word 'progress'. Progress is its form rather than making progress being one of its features. Typically it constructs. It is occupied with building an ever more complicated structure. And even clarity is sought only as a means to this end, not as an end in itself. For me on the contrary clarity, perspicuity are valuable in themselves. I am not interested in constructing a building, so much as having a perspicuous view of the foundations of possible buildings.

The riddle does not exist. If a question can be put at all, then it can also be answered.

Telling someone something that he does not understand is pointless, even if you add that he will not understand it. (That so often happens with someone you love.) If you have a room which you do not want certain people to get into, put a lock on it for which they do not have the key. But there is no point in talking to them about it, unless of course you want them to admire the room from the outside!

The honourable thing to do is to put a lock on the door which will be noticed only by those who can open it, not by the rest.
