With the growth of knowledge our ideas must from time to time be organized afresh. The change takes place usually in accordance with new maxims as they arise, but it always remains provisional.
Johann Wolfgang von GoetheNot all that is presented to us as history has really happened; and what really happened did not actually happen the way it is presented to us; moreover, what really happened is only a small part of all that happened. Everything in history remains uncertain, the largest events as well as the smallest occurrence.
Johann Wolfgang von Goethe
