A great thought begins by seeing something differently, with a shift of the mind's eye.

Out of complexity, find simplicity!

Science can only ascertain what is, but not what should be, and outside of its domain value judgements of all kinds remain necessary.

With fame I become more and more stupid, which of course is a very common phenomenon.

The world will not be destroyed by those who do evil, but by those who watch them without doing anything.

Not all things worth counting are countable and not all things that count are worth counting.

In my view, it is the most important function of art and science to awaken this feeling and keep it alive in those who are capable of it.
