It's impossible for me to say one word about all that music has meant to me in my life. How, then, can I hope to be understood?

It is not humanly possible to gather immediately from it what the logic of language is. Language disguises thought.

The real discovery is the one which enables me to stop doing philosophy when I want to. The one that gives philosophy peace, so that it is no longer tormented by questions which bring itself into question.

The philosophical I is not the human being, not the human body or the human soul with the psychological properties, but the metaphysical subject, the boundary (not a part) of the world.

The sense of the world must lie outside the world... What we cannot speak about we must remain silent about... What can be described can happen too, and what is excluded by the laws of causality cannot be described.

Courage, not cleverness; not even inspiration, is the grain of mustard that grows up to be a great tree.

Because our goals are not lofty but illusory, our problems are not difficult, but nonsensical.
