Abstract
The Anvil Book series offers a set of short, paper–back monographs by specialists in history and social science upon special periods or movements of thought. Three of its opening works deal sensibly with those highly ambiguous, but aggressively sentimental terms, Rationalism, Liberalism and Conservatism which in the past three centuries have managed to impose a verbal fetish upon their shifting detail of speculative philosophy and politico–economic policy. It is no small service to the contemporary student to clearly analyse the historical origins and development of each line of thought. And the method is uniformly successful in each book: approximately one hundred pages are devoted to an historico–critical analysis of each topic, followed by a ninety page selection of classic texts from its leading spirits.
