"Logic is not a body of doctrine, but a mirror-image of the world. Logic is transcendental."

Body

"Language disguises the thought; so that from the external form of the clothes one cannot infer the form of the thought they clothe, because the external form of the clothes is constructed with quite another object than to let the form of the body be recognized."

Knowledge

"For a truly religious man nothing is tragic."

Man

"Uttering a word is like striking a note on the keyboard of the imagination."

Imagination

"The truly apocalyptic view of the world is that things do not repeat themselves. It isn't absurd, e.g., to believe that the age of science and technology is the beginning of the end for humanity; that the idea of great progress is delusion, along with the idea that the truth will ultimately be known; that there is nothing good or desirable about scientific knowledge and that mankind, in seeking it, is falling into a trap. It is by no means obvious that this is not how things are."

Science

"Resting on your laurels is as dangerous as resting when you are walking in the snow. You doze off and die in your sleep."

Sleep

"If someone does not believe in fairies, he does not need to teach his children 'There are no fairies'; he can omit to teach them the word 'fairy'."

Parenting

"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."

Problems

"Imagine a person whose memory could not retain what the word 'pain' meant-so that he constantly called different things by that name-but nevertheless used the word in a way fitting in with the usual symptoms and presuppositions of 'pain'-in short he uses it as we all do. Here I should like to say: a wheel that can be turned though nothing else moves with it, is not part of the mechanism."

Memory

"We feel that even if all possible scientific questions be answered, the problems of life have still not been touched at all."
