There is today a frightful disappearance of living species, be they plants or animals. And it's clear that the density of human beings has become so great, if I can say so, that they have begun to poison themselves. And the world in which I am finishing my existence is no longer a world that I like.

I can't help thinking that science would be more appealing if it had no practical use.

Animals are good to think with.

The musical emotion springs precisely from the fact that at each moment the composer withholds or adds more or less than the listener anticipates on the basis of a pattern that he thinks he can guess, but that he is incapable of wholly divining. . . .

The scientist is not a person who gives the right answers, he is one who asks the right questions.

The musical emotion springs precisely from the fact that at each moment the composer withholds or adds more or less than the listener anticipates on the basis of a pattern that he thinks he can guess, but that he is incapable of wholly divining. If the composer withholds more than we anticipate, we experience a delicious falling sensation; we feel we have been torn from a stable point on the musical ladder and thrust into the void. When the composer withholds less, the opposite occurs: he forces us to perform gymnastic exercises more skillful than our own.
