The limits of my language means the limits of my world.

It is truly strange how long it takes to get to know oneself. I am now sixty two years old, yet just one moment ago I realised that I absolutely love lightly toasted bread. Simultaneously, I also realised that I loathe bread when it is heavily toasted. For almost sixty years, and quite unconsciously, I have been experiencing inner joy or total despair at my relationship with grilled bread.

There are, indeed, things that cannot be put into words. They make themselves manifest. They are what is mystical.

Everything that can be thought at all can be thought clearly. Everything that can be said can be said clearly. Ludwig Wittgenstein

Don't get involved in partial problems, but always take flight to where there is a free view over the whole single great problem, even if this view is still not a clear one.

Logic must look after itself. In a certain sense, we cannot make mistakes in logic.

If, for example, you were to think more deeply about death, then it would be truly strange if, in so doing, you did not encounter new images.
