Human progress is achieved by taking exact measurements. - William F. Buckley Jr.

Conservatism aims to maintain in working order the loyalties of the community to perceived truths and also to those truths which in their judgment have earned universal recognition.

They [progressives] are men and women who tend to believe that the human being is perfectible and social progress predictable, and that the instrument for effecting the two is reason; that truths are transitory and empirically determined; that equality is desirable and attainable through the action of state power; that social and individual differences, if they are not rational, are objectionable, and should be scientifically eliminated; that all people and societies strive to organize themselves upon a rationalist and scientific paradigm.

He was a conservative all right, but invariably he gave the impression that he was a conservative because he was surrounded by liberals; that he had been a revolutionist if that had been required in order to be socially disruptive.
