But not my tyrant. For the spirit needs
Impulses from a deeper source than hers;
And there are motions, in the mind of man,
That she must look upon with awe.

- The intellect has only one failing, which to be sure, is a very considerable one. It has no conscience. Napoleon is the readiest instance of this. If his heart had borne any proportion to his brain, he had been one of the greatest men of history.

- Peter Medawar, Advice to a Young Scientist (1979).
- I once spoke to a human geneticist who declared that the notion of intelligence was quite meaningless, so I tried calling him unintelligent.

- I'll call "Society of Mind" this scheme in which each mind is made of many smaller processes. These we'll call agents. Each mental agent by itself can only do some simple thing that needs no mind at all. Yet when we join these agents in societies—in very special ways—this leads to true intelligence.
- Marvin Minsky, The Society of Mind (1988).

- Cesare Pavese, The moon and the bonfire, chapter XVII, p. 99.
- Psychology, speaking for emotion and instinct, has reduced intellect to impotence over life. Metaphysics has subordinated it to will. Bergson and his followers have charged it with falsehood and issued a general warning against its misrepresentations; while with pragmatists and instrumentalists it has sunk so low that it is dressed in livery and sent to live in the servant's quarters. It is against this last indignity in particular that I wish to speak a word of protest, to the end that the intellect may be accorded full rights within the community of human activities and interests.
- Ralph Barton Perry, "The Integrity of the Intellect," Harvard Theological Review, vol. 13, no. 3, July 1920, pp.220-221.
- As the saints and prophets were often forced to practise long vigils and fastings and prayers before their ecstasies would fall upon them and their visions would appear, so Virtue in its purest and most exalted form can only be acquired by means of severe and long continued culture of the mind. Persons with feeble and untrained intellects may live according to their conscience; but the conscience itself will be defective. … To cultivate the intellect is therefore a religious duty; and when this truth is fairly recognized by men, the religion which teaches that the intellect should be distrusted and that it should be subservient to faith, will inevitably fall.
- William Winwood Reade, The Martyrdom of Man (1872), p. 540.
- Every thing connected with intellect is permanent.
- William Roscoe, reported in Dictionary of Burning Words of Brilliant Writers (1895) by Josiah Hotchkiss Gilbert, p. 353.
- We live in a culture in which intelligence is denied relevance altogether, in a search for radical innocence, or is defended as an instrument of authority and repression. In my view, the only intelligence worth defending is critical, dialectical, skeptical, desimplifying.
