Arthur Schopenhauer on Knowledge

"Obstinacy is the result of the will forcing itself into the place of the intellect."

"A reproach can only hurt if it hits the mark. Whoever knows that he does not deserve a reproach can treat it with contempt."

"Patriotism, when it wants to make itself felt in the domain of learning, is a dirty fellow who should be thrown out of doors."

"This actual world of what is knowable, in which we are and which is in us, remains both the material and the limit of our consideration."

"Only a male intellect clouded by the sexual drive could call the stunted, narrow-shouldered, broad-hipped and short-legged sex the fair sex."

"Talent hits a target no one else can hit; Genius hits a target no one else can see."

"The fundament upon which all our knowledge and learning rests is the inexplicable."

"Intellect is invisible to the man who has none."

"That books do not take the place of experience, and that learning is no substitute for genius, are two kindred phenomena; their common ground is that the abstract can never take the place of the perceptive."

"We, on the contrary, now send to the Brahmans English clergymen and evangelical linen-weavers, in order out of sympathy to put them right, and to point out to them that they are created out ofnothmg, and that they ought to be grateful and pleased about it. But it is Just the same as if we fired a bullet at a cliff. " In India, our religions wIll never at any time take root; the ancient wisdom of the human race will not be supplanted by the events in Galilee. On the contrary, Indian Wisdom flows back to Europe, and will produce a fundamental change in our knowledge and thought."

"The charlatan takes very different shapes according to circumstances; but at bottom he is a man who cares nothing about knowledge for its own sake, and only strives to gain the semblance of it that he may use it for his own personal ends, which are always selfish and material."

"Two Chinamen visiting Europe went to the theatre for the first time. One of them occupied himself with trying to understand the theatrical machinery, which he succeeded in doing. The other, despite his ignorance of the language, sought to unravel the meaning of the play. The former is like the astronomer, the latter the philosopher."

"For a work to become immortal it must possess so many excellences that it will not be easy to find a man who understands and values them all; so that there will be in all ages men who recognise and appreciate some of these excellences; by this means the credit of the work will be retained throughout the long course of centuries and ever-changing interests, for, as it is appreciated first in this sense, then in that, the interest is never exhausted."

"Spinoza says that if a stone which has been projected through the air, had consciousness, it would believe that it was moving of its own free will. I add this only, that the stone would be right. The impulse given it is for the stone what the motive is for me, and what in the case of the stone appears as cohesion, gravitation, rigidity, is in its inner nature the same as that which I recognise in myself as will, and what the stone also, if knowledge were given to it, would recognise as will."

"As the biggest library if it is in disorder is not as useful as a small but well-arranged one, so you may accumulate a vast amount of knowledge but it will be of far less value to you than a much smaller amount if you have not thought it over for yourself; because only through ordering what you know by comparing every truth with every other truth can you take complete possession of your knowledge and get it into your power. You can think about only what you know, so you ought to learn something; on the other hand, you can know only what you have thought about."

"And now that I have allowed myself the jest to which in this two-sided life hardly any page can be too serious to grant a place, I part with the book with deep seriousness, in the sure hope that sooner or later it will reach those to whom alone it can be addressed; and for the rest, patiently resigned that the same fate should, in full measure, befall it, that in all ages has, to some extent, befallen all knowledge, and especially the weightiest knowledge of the truth, to which only a brief triumph is allotted between the two long periods in which it is condemned as paradoxical or disparaged as trivial. The former fate is also wont to befall its author. But life is short, and truth works far and lives long: let us speak the truth."

"To free a man from error is to give, not to take away. Knowledge that a thing is false is a truth. Error always does harm; sooner or later it will bring mischief to the man who harbors it. Then give up deceiving people; confess ignorance of what you don't know, and leave everyone to form his own articles of faith for himself. Perhaps they won't turn out so bad, especially as they'll rub one another's corners down, and mutually rectify mistakes. The existence of many views will at any rate lay a foundation of tolerance. Those who possess knowledge and capacity may betake themselves to the study of philosophy, or even in their own persons carry the history of philosophy a step further."

"To be a philosopher, that is to say, a lover of wisdom , it is not enough for a man to love truth, in so far as it is compatible with his own interest, with the will of his superiors, with the dogmas of the church, or with the prejudices and tastes of his contemporaries; so long as he rests content with this position, he is only a philautos, not a philosophos . For this title of honor is well and wisely conceived precisely by its stating that one should love the truth earnestly and with one’s whole heart, and thus unconditionally and unreservedly, above all else, and, if need be, in defiance of all else. Now the reason for this is the one previously stated that the intellect has become free, and in this state it does not even know or understand any other interest than that of truth."
