"If the basis of a popular government in peacetime is virtue, its basis in a time of revolution is virtue and terror -- virtue, without which terror would be barbaric; and terror, without which virtue would be impotent." [Robespierre, speech in Fr. National Convention, 1794]General sense of "systematic use of terror as a policy" is first recorded in Eng. 1798. Terrorize "coerce or deter by terror" first recorded 1823. Terrorist in the modern sense dates to 1947, especially in reference to Jewish tactics against the British in Palestine -- earlier it was used of extremist revolutionaries in Russia (1866); and Jacobins during the French Revolution (1795) -- from Fr. terroriste. The tendency of one party's terrorist to be another's guerilla or freedom fighter was noted in ref. to the British action in Cyprus (1956) and the war in Rhodesia (1973). The word terrorist has been applied, at least retroactively, to the Maquis resistance in occupied France in World War II (e.g. in the "Spectator," Oct. 20, 1979).
"Strictly speaking, conservatism is not a political system, but rather a way of looking at the civil order. The conservative of Peru ... will differ greatly from those of Australia, for though they may share a preference for things established, the institutions and customs which they desire to preserve are not identical." [Russell Kirk (1918-1994)]Phrases such as a conservative estimate make no sense etymologically.
"... in the spring of 1834 Jackson's opponents adopted the name Whig, traditional term for critics of executive usurpations. James Watson Webb, editor of the New York Courier and Enquirer, encouraged use of the name. [Henry] Clay gave it national currency in a speech on April 14, 1834, likening "the whigs of the present day" to those who had resisted George III, and by summer it was official." [Daniel Walker Howe, "What Hath God Wrought," 2007, p.390]Whig historian is recorded from 1924. Whig history is "the tendency in many historians ... to emphasise certain principles of progress in the past and to produce a story which is the ratification if not the glorification of the present." [Herbert Butterfield, "The Whig Interpretation of History," 1931]
