quotations about thought
Learning without thought is labor lost; and thought without learning is perilous.
CONFUCIUS
attributed, Day's Collacon
It is the compelling power of great thoughts and ideas to engender phrases of equal size.
ARISTOPHANES
The Frogs
The measure of greatness in a scientific idea is the extent to which it stimulates thought and opens up new lines of research.
PAUL ADRIAN MAURICE DIRAC
attributed, Cosmology of Lemaître
There is no God, no universe, no human race, no earthly life, no heaven, no hell. It is all a Dream, a grotesque and foolish dream. Nothing exists but you. And You are but a Thought -- a vagrant Thought, a useless Thought, a homeless Thought, wandering forlorn among the empty eternities.
MARK TWAIN
The Mysterious Stranger
Thought can wing its way
Swifter than lightning-flashes or the beam
That hastens on the pinions of the morn.
JAMES GATES PERCIVAL
"Sonnet", Clio
A penny for your thought.
JOHN LYLY
Euphues
Beware of producing crude thoughts; study till thy words are matured.
PTAH HOTEP
attributed, Day's Collacon
Thought is the wind, knowledge the sail, and mankind the vessel.
JULIUS CHARLES HARE
Guesses at Truth
Never know whose thoughts you're chewing.
JAMES JOYCE
Ulysses
It is doubtful whether our present system of popular education does not retard independent or self thinking as much as it promotes it. All genuine education is self-education. It will incite the individual to think for himself, by rethinking what the race's great thinkers have already thought for him, thus enabling him to go ahead under his own mental steam.
JOSEPH ALEXANDER LEIGHTON
The Field of Philosophy
Thought obeys no natural law. In a stream of water, time works the way it usually does in nature -- the future passes into the present and then into the past. In thought, the past might pour into the present and then drain away into the future. Or the future might rain into the past as the present disappears. Thought is not like a natural thing. Thought is literally the essence of the artificial.
MICHAEL W. CLUNE
"Thought Against Life: Cyrus Console's 'Romanian Notebook'", L.A. Review of Books, May 21, 2017
A new thought belongs to the world, and is no man's patent.
HERBERT TUTTLE
attributed, Day's Collacon
His high-erected thoughts look'd down upon
The smiling valley of his fruitful heart.
DANIEL WEBSTER
A Monumental Column
Sudden a thought came like a full-blown rose,
Flushing his brow, and in his pained heart
Made purple riot.
JOHN KEATS
"The Eve of Saint Agnes"
If what we think now is different from what we thought then, we can take it for granted that what we think in a year will be different again.
DORIS LESSING
Shikasta
Our thoughts are often worse than we are, just as they are often better than we are.
GEORGE ELIOT
Mr. Gilfil's Love Story
A profound thought is in a constant state of becoming; it adopts the experience of a life and assumes its shape.
ALBERT CAMUS
The Myth of Sisyphus
Nothing is so fragile as thought in its infancy; an interruption breaks it: nothing is so powerful, even to overturning empires, when it reaches its maturity.
CHRISTIAN NESTELL BOVEE
Intuitions and Summaries of Thought
Heresy is only another word for freedom of thought.
GRAHAM GREENE
The Spectator, April 18, 1981
Think wrongly, if you please, but in all cases think for yourself.
DORIS LESSING
