Philosophy is written in this grand book-I mean the universe-which stands continually open to our gaze, but it cannot be understood unless one first learns to comprehend the language and interpret the characters in which it is written. It is written in the language of mathematics, and its characters are triangles, circles, and other geometrical figures, without which it is humanly impossible to understand a single word of it; without these, one is wandering about in a dark labyrinth. — Galileo Galilei · 1623God made integers, all else is the work of man. — Leopold Kronecker · 1886If we take in our hand any volume; of divinity or school metaphysics, for instance; let us ask, Does it contain any abstract reasoning concerning quantity or number? No. Does it contain any experimental reasoning, concerning matter of fact and existence? No. Commit it then to the flames: For it can contain nothing but sophistry and illusion. — David Hume · 1748The mathematician's patterns, like the painter's or the poet's, must be beautiful; the ideas, like the colors or the words, must fit together in a harmonious way. Beauty is the first test: there is no permanent place in the world for ugly mathematics. — G.H. Hardy · 1940The great advantage of the mathematical sciences above the moral consists in this, that the ideas of the former, being sensible, are always clear and determinate. — David Hume · 1748Mathematics is the science which draws necessary conclusions. — Benjamin Peirce · 1870All 11 quotes →

Mathematics, rightly viewed, possesses not only truth, but supreme beauty—a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show. — Bertrand Russell · 1907
When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind: it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science. — William Thomson, Lord Kelvin · 1883

Mathematics takes us still further from what is human, into the region of absolute necessity, to which only the actual world, but every possible world, must conform. — Bertrand Russell · 1907

The theory of probabilities is at bottom only common sense reduced to calculus. — Pierre-Simon Laplace · 1814

No. Does it contain any experimental reasoning, concerning matter of fact and existence? No. Commit it then to the flames: For it can contain nothing but sophistry and illusion. — David Hume · 1748
