„But though all our knowledge begins with experience, it by no means follows, that all arises out of experience.“

—  Immanuel Kant German philosopher 1724 - 1804
Context: That all our knowledge begins with experience there can be no doubt. For how is it possible that the faculty of cognition should be awakened into exercise otherwise than by means of objects which affect our senses, and partly of them selves produce representations, partly rouse our powers of understanding into activity, to compare, to connect, or to separate these, and so to convert the raw material of our sensuous impressions into a knowledge of objects, which is called experience? In respect of time, therefore, no knowledge of ours is antecedent to experience, but begins with it. But though all our knowledge begins with experience, it by no means follows, that all arises out of experience. For, on the contrary, it is quite possible that our empirical knowledge is a compound of that which we receive through impressions, and that which the faculty of cognition supplies from itself (sensuous impressions giving merely the occasion)... It is, therefore, a question which requires close investigation, and is not to be answered at first sight,—whether there exists a knowledge altogether independent of experience, and even of all sensuous impressions? Knowledge of this kind is called à priori, in contradistinction to empirical knowledge which has its sources à posteriori, that is, in experience. Introduction I. Of the Difference Between Pure and Empirical Knowledge

„Information is not knowledge. The only source of knowledge is experience.“

—  Albert Einstein German-born physicist and founder of the theory of relativity 1879 - 1955
According to Barbara Wolff, of The Hebrew University's Albert Einstein Archives, this is not one of Einstein's identifiable quotations. (Source: paralegalpie.com http://www.paralegalpie.com/paralegalpie/2009/11/did-anybody-really-say-that.html.) The phrase "the only source of knowledge is experience" is found in an English-language essay from 1896: "We can only be guided by what we know, and our only source of knowledge is experience" (Arthur J. Pillsbury, "The Final Word" https://books.google.com/books?id=Mw9IAQAAMAAJ&pg=PA595&dq=%22only+source", Overland Monthly, November 1896). The thought can be seen as a paraphrase of John Locke's argument from his Essay Concerning Human Understanding: "Whence has it [the Mind] all the materials of Reason and Knowledge? To this I answer, in one Word, From Experience". (Locke, An Essay Concerning Human Understanding/Book II/Chapter I, 2.) The phrase "information is not knowledge" is also found from the nineteenth century https://books.google.com/books?id=W2oAAAAAMAAJ&pg=PA59&dq=%22information+is+not+knowledge%22.

„The best definition of true imagination is that it is the sum of our faculties. Poetry is the scholar's art.“

—  Wallace Stevens American poet 1879 - 1955
Context: The best definition of true imagination is that it is the sum of our faculties. Poetry is the scholar's art. The acute intelligence of the imagination, the illimitable resources of its memory, its power to possess the moment it perceives — if we were speaking of light itself, and thinking of the relationship between objects and light, no further demonstration would be necessary... What light requires a day to do, and by day I mean a kind of Biblical revolution of time, the imagination does in the twinkling of an eye. It colors, increases, brings to a beginning and end, invents languages, crushes men, and, for that matter, gods in its hands, it says to women more than it is possible to say, it rescues all of us from what we have called absolute fact...

„Our mind (and there are no individual minds — only "mind", which is the accumulation of man's knowledge and experience) has created the notion of the psyche and evolution.“

—  U.G. Krishnamurti Indian philosopher 1918 - 2007
Context: Our mind (and there are no individual minds — only "mind", which is the accumulation of man's knowledge and experience) has created the notion of the psyche and evolution. Only technology progresses, while we as a race are moving closer to complete and total destruction of the world and ourselves. Everything in man's consciousness is pushing the whole world, which nature has so laboriously created, toward destruction. There has been no qualitative change in man's thinking; we feel about our neighbours just as the frightened caveman felt towards his. The only thing that has changed is our ability to destroy our neighbor and his property. Ch. 1: The Certainty That Blasts Everything
