„There are here two assumptions about 'evaluations ', which I will call assumption (1) and assumption (2). Assumption (1) is that some individual may, without logical error, base his beliefs about matters of value entirely on premises which no one else would recognise as giving any evidence at all. Assumption (2) is that, given the kind of statement which other people regard as evidence for an evaluative conclusion, he may refuse to draw the conclusion because this does not count as evidence for him.“

„In the realm of faith, God is not a hypothesis derived from logical assumptions, but an immediate insight, self-evident as light.“

— Abraham Joshua Heschel Polish-American Conservative Judaism Rabbi 1907 - 1972
Context: In the realm of faith, God is not a hypothesis derived from logical assumptions, but an immediate insight, self-evident as light. To rationalists He is something after which they seek in the darkness with the light of their reason. To men of faith He is the light. "The Holy Dimension", p. 337. Heschel made similar statements in earlier writings: The great insight is not attained when we ponder or infer the beyond from the here. In the realm of the ineffable, God is not a hypothesis derived from logical assumptions, but an immediate insight, self-evident as light. He is not something to be sought in the darkness with the light of reason. He is the light. Man Is Not Alone : A Philosophy of Religion (1951)

„Mathematical reasoning may be regarded rather schematically as the exercise of a combination of two facilities, which we may call intuition and ingenuity.“

— Alan Turing British mathematician, logician, cryptanalyst, and computer scientist 1912 - 1954
Context: Mathematical reasoning may be regarded rather schematically as the exercise of a combination of two facilities, which we may call intuition and ingenuity. The activity of the intuition consists in making spontaneous judgements which are not the result of conscious trains of reasoning... The exercise of ingenuity in mathematics consists in aiding the intuition through suitable arrangements of propositions, and perhaps geometrical figures or drawings. "Systems of Logic Based on Ordinals," section 11: The purpose of ordinal logics (1938), published in Proceedings of the London Mathematical Society, series 2, vol. 45 (1939) In a footnote to the first sentence, Turing added: "We are leaving out of account that most important faculty which distinguishes topics of interest from others; in fact, we are regarding the function of the mathematician as simply to determine the truth or falsity of propositions."

„Yes, evolution by descent from a common ancestor is clearly true. If there was any lingering doubt about the evidence from the fossil record, the study of DNA provides the strongest possible proof of our relatedness to all other living things.“
