The physicists say that I am a mathematician, and the mathematicians say that I am a physicist. I am a completely isolated man and though everybody knows me, there are very few people who really know me.
Because a fact seems strange to you, you conclude that it is not one. ... All science, however, commences by being strange. Science is successive. It goes from one wonder to another. It mounts by a ladder. The science of to-day would seem extravagant to the science of a former time. Ptolemy would believe Newton mad.
Pure mathematics is, in its way, the poetry of logical ideas. ... [By seeking] logical beauty spiritual formulas are discovered necessary for the deeper penetration into the laws of nature.
I have been scientifically studying the traits and dispositions of the "lower animals" (so-called,) and contrasting them with the traits and dispositions of man. I find the result profoundly humiliating to me. For it obliges me to renounce my allegiance to the Darwinian theory of the Ascent of Man from the Lower Animals; since it now seems plain to me that that theory ought to be vacated in favor of a new and truer one, this new and truer one to be named the Descent of Man from the Higher Animals.
Our national policies will not be revoked or modified, even for scientists. If the dismissal of Jewish scientists means the annihilation of contemporary German science, then we shall do without science for a few years.
Stay in college, get the knowledge. And stay there until you're through. If they can make penicillin out of moldy bread, they can sure make something out of you. Advice to a young person to continue his education.
One thing I have learned in a long life: that all our science, measured against reality, is primitive and childlike -- and yet it is the most precious thing we have.
Therefore the moon, the governess of floods,
Pale in her anger washes all the air,
That rheumatic diseases do abound;
And through this distemperature we see
The seasons alter: hoary-headed frosts
Fall in the fresh lap of the crimson rose.
Species do not grow more perfect: the weaker dominate the strong, again and again- the reason being that they are the great majority, and they are also cleverer. Darwin forgot the mind (-that is English!): the weak possess more mind. ... To acquire mind, one must need mind-one loses it when one no longer needs it.
Index-learning turns no student pale,
Yet holds the eel of Science by the tail.
Index-learning is a term used to mock pretenders who acquire superficial knowledge merely by consulting indexes.
Marxism: The theory that all the important things in history are rooted in an economic motive, that history is a science, a science of the search for food.
If someone separated the art of counting and measuring and weighing from all the other arts, what was left of each (of the others) would be, so to speak, insignificant.
The terrible tabulation of the French statists brings every piece of whim and humor to be reducible also to exact numerical ratios. If one man in twenty thousand, or in thirty thousand, eats shoes, or marries his grandmother, then, in every twenty thousand, or thirty thousand, is found one man who eats shoes, or marries his grandmother.
