"The founding fathers of modern philosophy . . . went so far as to assert that, just as the knowledge of each individual progresses in the course of his life, the knowledge of the whole human race necessarily advances from day to day, i.e., from generation to generation. In asserting this, they underrated the difference between inherited knowledge, i.e., the knowledge which one acquires in schools and universities, and independently acquired knowledge, i.e., knowledge acquired by a mature scholar. Thus it came to pass that inherited knowledge was given the same cognitive status as independently acquired knowledge. (Witness the phrase: the results of modern research.) Whereas, actually, inherited knowledge is hardly distinguishable from prejudice: inherited knowledge is, in the typical case, a collection of true prejudices. . . . In some cases, it so happens that what, to begin with, is supposed to be inherited knowledge or true prejudice proves to be an inherited error."
Leo Strauss "Historicism" (1941 lecture)
