I am my world.

The world is the totality of facts, not of things

The fact that we can describe the motions of the world using Newtonian mechanics tell us nothing about the world. The fact that we do, does tell us something about the world.

With my full philosophical rucksack I can only climb slowly up the mountain of mathematics.

If people did not sometimes do silly things, nothing intelligent would ever get done.

Almost in the same way as earlier physicists are said to have found suddenly that they had too little mathematical understanding to be able to master physics; we may say that young people today are suddenly in the position that ordinary common sense no longer suffices to meet the strange demands life makes. Everything has become so intricate that for its mastery an exceptional degree of understanding is required. For it is not enough any longer to be able to play the game well; but the question is again and again: what sort of game is to be played now anyway?

Our greatest stupidities may be very wise.
