“Knowledge isolates phenomena and things to observe with.... nothing is isolatable or can be removed from its environment. Anything which becomes isolated ceases to exist. It is like the violent refusal of someone to play a game in which everyone cheats.”

On Contradiction (1937)

Ben Yamen's Song of Geometry (1853)
Context: The Key! it is of wonderful construction, with its infinity of combination, and its unlimited capacity to fit every lock. … it is the great master-key which unlocks every door of knowledge and without which no discovery which deserves the name — which is law, and not isolated fact — has been or ever can be made. Fascinated by its symmetry the geometer may at times have been too exclusively engrossed with his science, forgetful of its applications; he may have exalted it into his idol and worshipped it; he may have degraded it into his toy... when he should have been hard at work with it, using it for the benefit of mankind and the glory of his Creator.

Treason (1988)

Free Culture (2004)
Context: We, the most powerful democracy in the world, have developed a strong norm against talking about politics. It's fine to talk about politics with people you agree with. But it is rude to argue about politics with people you disagree with. Political discourse becomes isolated, and isolated discourse becomes more extreme. We say what our friends want to hear, and hear very little beyond what our friends say.

Original: Nunca fui mais que um boémio isolado, o que é um absurdo; ou um boémio místico, o que é uma coisa impossível.

What is Enlightenment? (1784)
Context: It is difficult for the isolated individual to work himself out of the immaturity which has become almost natural for him. He has even become fond of it and for the time being is incapable of employing his own intelligence, because he has never been allowed to make the attempt. Statutes and formulas, these mechanical tools of a serviceable use, or rather misuse, of his natural faculties, are the ankle-chains of a continuous immaturity. Whoever threw it off would make an uncertain jump over the smallest trench because he is not accustomed to such free movement. Therefore there are only a few who have pursued a firm path and have succeeded in escaping from immaturity by their own cultivation of the mind.
