Bertrand Russell, A History of Western Philosophy

"Two things are to be remembered: that a man whose opinions and theories are worth studying may be presumed to have had some intelligence, but that no man is likely to have arrived at complete and final truth on any subject whatever. When an intelligent man expresses a view which seems to us obviously absurd, we should not attempt to prove that it is somehow true, but we should try to understand how it ever came toseemtrue. Thisexercise of historical and psychological imagination at once enlarges the scope of our thinking, and helps us to realize how foolish many of our own cherished prejudices will seem to an age which has a different temper of mind."

"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."

"What Galileo and Newton were to the seventeenth century, Darwin was to the nineteenth."

"Ever since Plato most philosophers have considered it part of their business to produce ‘proofs’ of immortality and the existence of God. They have found fault with the proofs of their predecessors — Saint Thomas rejected Saint Anselm's proofs, and Kant rejected Descartes' — but they have supplied new ones of their own. In order to make their proofs seem valid, they have had to falsify logic, to make mathematics mystical, and to pretend that deepseated prejudices were heaven-sent intuitions."

"Science tells us what we can know, but what we can know is little, and if we forget how much we cannot know, we become insensitive to many things of great importance."

"The problem of finding a collection of “wise” men and leaving the government to them is thus an insoluble one. That is the ultimate reason for democracy."

"Liberation from the tyranny of the body contributes to greatness, but just as much to greatness in sin as to greatness in virtue."

"A stupid man's report of what a clever man says can never be accurate, because he unconsciously translates what he hears into something he can understand."

"Однако существует довод и более общего характера против слепого преклонения перед греками или кем бы то ни было еще. Правильное отношение к изучению того или иного философа состоит не в том, чтобы почитать или презирать его, но прежде всего в некоторого рода предрасположенности, дающей возможность понять, что именно склоняет к тому, чтобы верить в его теории, и только потом следует оживлять критическое отношение, которое должно напоминать, насколько это возможно, состояние ума той личности, которая отбрасывает мнения, отстаиваемые ею прежде. Презрение мешает первой части этого процесса, преклонение – второй. Следует при этом учитывать две вещи: надо помнить, что человек, чьи взгляды и теории заслуживают изучения, должен, по-видимому, обладать определенным умом, но надо также иметь в виду, что ни один человек не достигал, вероятно, полной и окончательной истины по какому бы то ни было вопросу. Когда умный человек выражает совершенно абсурдный с нашей точки зрения взгляд, мы не должны пытаться доказывать, что этот взгляд тем не менее является правильным, но нам следует попытаться понять, каким образом этот взгляд когда-то казался правильным. Это упражнение исторического и психологического воображения одновременно и расширяет сферу нашего мышления, и помогает нам понять, насколько глупыми многие из лелеемых нами предрассудков покажутся веку, обладающему другим складом ума."

"William James describes a man who got the experience from laughing-gas; whenever he was under its influence, he knew the secret of the universe, but when he came to, he had forgotten it. At last, with immense effort, he wrote down the secret before the vision had faded. When completely recovered, he rushed to see what he had written. It was: "A smell of petroleum prevails throughout."

"The search for something permanent is one of the deepest of the instincts leading men to philosophy."

"Almost everything that distinguishes the modern world from earlier centuries is attibutable to science, which achieved its most spectacular triumphs in the seventeenth century."

"To teach how to live without certainty, and yet without being paralyzed by hesitation, is perhaps the chief thing that philosophy, in our age, can still do for those who study it."
