The historian and the facts of history are necessary to one another. The historian without his facts is rootless and futile; the facts without their … - E. H. Carr

History therefore is a process of selection in terms of historical significance. To borrow Talcott Parsons’s phrase once more, history is ‘a selective system’ not only of cognitive, but of causal, orientations to reality. Just as from the infinite ocean of facts the historian selects those which are significant for his purpose, so from the multiplicity of sequences of cause and effect he extracts those, and only those, which are historically significant; and the standard of historical significance is his ability to fit them into his pattern of rational explanation and interpretation.

The essential result of the French revolution was to establish the doctrine of popular sovereignty as the foundation of modern Europe, though with no more precise definition of that elusive category "the people" than that popular sovereignty was the antithesis of the personal authority of the monarch.

Facts cannot be derived from values. This is partly true, but may also be misleading, and requires qualification. When we seek to know the facts, the questions which we ask, and therefore the answers which we obtain, are prompted by our system of values. Our picture of the facts of our environment is moulded by our values, i.e. by the categories through which we approach the facts; and this picture is one of the important facts of which we have to take into account. Values enter into the facts and are an essential part of them. Our values are an essential part of our equipment as human beings. It is through our values that we have that capacity to adapt ourselves to our environment, and to adapt our environment to ourselves, to acquire that mastery over our environment, which has made history a record of progress. But do not, in dramatizing the struggle of man with his environment, set up a false antithesis and a false separation between facts and values. Progress in history is achieved through the interdependence and interaction of facts and values. The objective historian is the historian who penetrates most deeply into this reciprocal process.
