The Uncertainty Principle

Historical understanding can never produce results which must be accepted by all men. Two historians who fully agree with regard to the teachings of the non historical sciences, may disagree in their understanding of the re vance of these facts. The intellectual methods of science do not differ in kind from those applied by the common man in his daily, mundane reasoning. Understanding is not a privilege of the historians. It is everybody's business in observing the conditions of his environment. Acting man looks, as it were, with the eyes of a historian into the future.
