Russell was one of influential Western philosophers in this twentieth century. Though known as a philosopher, he was also a history theorist. He revolted against the philosophy of history, which for him is nothing but a myth. Nor did he regard history as a science. He believed that history is, as a matter of fact, a knowledge about human beings' empirical life, it therefore has its own characteristics. Ancient Western historians bequeathed us many appealing works; nevertheless, since the rise of the scientific way of studying history in recent times, profound works on history have been dwindling. Russell praisd much four Western historians; they are: Herodotus, Thucydides, Plutarch, and Edward Gibbon. He had made deep-going commentaries on them, from which we can learn many gridelines for the purpose of studying history. Russell's major opinions are as follows: first of all, historical scholars have better find ever-develop ing topics which can be studied for a long time; secondly, works on history must own the powerof catching readers' attention; thirdly, scholars should value not only the change of the society but also the influence of individuals on the development of history; fourthly, scholars should have a correct historical sensibility; and last but not least, scholars must have holistic understanding of historical events. These views are of great value to those who want to make breakthroughs in the field of history study.
