“I have extensive management experience in crisis situations, accumulated experience, and knowledge in the security and defense system. I have experience in overcoming the economic crisis. The current dangers and the accumulated experience and knowledge practically coincide”

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.

Context: As we walk hand in hand through the pathways of knowledge, remember that I am giving you freely and without stint the full accumulation of my two months’ experience as a candidate. I have on file a complete record of everything I’ve said and done. Ever since I threw my hat in the ring I have had myself shadowed, and the results were very entertaining. The things that go on in those back rooms, you wouldn’t believe.
So now we begin our journey together. If you follow these instructions carefully, you will find that every step of your progress, like the path that climbs up and up from the sheltered valley, offers you an ever-wider and more facinating vista, until at last you come out upon the summit of the wrong hill.

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.
