“The melodic curves of speech are an expression of the complete organism and of all phases of its spiritual activities. They demonstrate whether a man is stupid or intelligent, sleepy or awake, tired or alert. They tell us whether he is a child or an old man, whether it is morning or evening, light or darkness, heat or frost, and disclose whether a person is alone or in company. The art of dramatic writing is to compose a melodic curve that will, as if by magic, reveal immediately a human being in one definite phase of his existence.”

Bennington College address (1970)
Context: The arts put man at the center of the universe, whether he belongs there or not. Military science, on the other hand, treats man as garbage — and his children, and his cities, too. Military science is probably right about the contemptibility of man in the vastness of the universe. Still — I deny that contemptibility, and I beg you to deny it, through the creation of appreciation of art.

The Gods Themselves (1972)
Context: "Don't finish, Pete. I've heard it all before. All I have to do is decipher the thinking of a non-human intelligence."
"A better-than-human intelligence. Those creatures from the para-Universe are trying to make themselves understood."
"That may be," sighed Bronowski, "but they're trying to do it through my intelligence, which is better than human I sometimes think, but not much. Sometimes, in the dark of the night, I lie awake and wonder if different intelligences can communicate at all; or, if I've had a particularly bad day, whether the phrase 'different intelligences' has meaning at all."
"It does," said Lamont savagely, his hands clearly bailing into fists within his lab coat pockets. "It means Hallam and me. It means that fool-hero, Dr. Frederick Hallam and me. We're different intelligences because when I talk to him he doesn't understand. His idiot face gets redder and his eyes bulge and his ears block. I'd say his mind stops functioning, but lack the proof of any other state from which it might stop."

Science and Immortality (1904)
Context: Though his philosophy finds nothing to support it, at least from the standpoint of Terence the scientific student should be ready to acknowledge the value of a belief in a hereafter as an asset in human life. In the presence of so many mysteries which have been unveiled, in the presence of so many yet unsolved, he cannot be dogmatic and deny the possibility of a future state; and however distressing such a negative attitude of mind to the Teresian, like Pyrrho, he will ask to be left, reserving his judgement, but still inquiring. He will recognize that amid the turbid ebb and flow of human misery, a belief in the resurrection of the dead and the life of the world to come is the rock of safety to which many of the noblest of his fellows have clung; he will gratefully accept the incalculable comfort of such a belief to those sorrowing for precious friends hid in death's dateless night; he will acknowledge with gratitude and reverence the service to humanity of the great souls who have departed this life in a sure and certain hope but this is all. Whether across death's threshold we step from life to life, or whether we go whence we shall not return, even to the land of darkness, as darkness itself, he cannot tell.
