It is nonsense to say that generalization is foreign to history; history thrives on generalizations. - E. H. Carr

History properly so-called can be written only by those who find and accept a sense of direction in history itself. The belief that we have come from somewhere is closely linked with the belief that we are going somewhere. A society which has lost belief in its capacity to progress in the future will quickly cease to concern itself with its progress in the past.

Scientists, social scientists and historians are all engaged in different branches of the same study: the study of man and his environment, of the effects of man on his environment and of his environment on man. The object of the study is the same: to increase man’s understanding of, and mastery over, his environment. The presuppositions and the methods of the physicist, the geologist, the psychologist and the historian differ widely in detail; nor do I wish to commit myself to the proposition that, in order to be more scientific, the historian must follow more closely the methods of physical science. But historian and physical scientist are united in the fundamental purpose of seeking to explain, and in the fundamental procedure of question and answer.

In short, with the triumph of the industrial revolution and its inevitable consequence, the rise of the class-conscious proletariat, nothing could ever be the same again-not even political revolutions.
