“Information is not knowledge. The only source of knowledge is experience.”
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.)

Context: Americans of all ages, all stations of life, and all types of disposition are forever forming associations... In democratic countries knowledge of how to combine is the mother of all other forms of knowledge; on its progress depends that of all the others.
Knowing Yourself: The True in the False (1996)
Context: You think: you become that thought. And consciousness, or the state of pure awareness, is lost. The highest knowledge man can possess is that which is true in his own experience. If his experience is limited, so is his knowledge and he behaves accordingly.
