Sir Herbert Butterfield was a British historian and philosopher of history who is remembered chiefly for two books—a short volume early in his career entitled The Whig Interpretation of History (1931) and his Origins of Modern Science (1949). Over the course of his career, Butterfield turned increasingly to historiography and man's developing view of the past. Butterfield was a devout Christian and reflected at length on Christian influences in historical perspectives. Butterfield thought individual personalities more important than great systems of government or economics in historical study. His Christian beliefs in personal sin, salvation, and providence heavily influenced his writings, a fact he freely admitted. At the same time, Butterfield's early works emphasized the limits of a historian's moral conclusions, "If history can do anything it is to remind us that all our judgments are merely relative to time and circumstance."
