Although 50 years ago some wag might have said the phrase "conservative and libertarian thought" is a redundant oxymoron, much has changed. Among other things, William Buckley founded National Review in the United States (1955), creating a respectable forum for conservative thought and an umbrella for disparate strands of political philosophy -- classical liberal, Southern agrarian, Straussian -- to come together for dialogue. Politically, the campaigns of Barry Goldwater (1964) and Ronald Reagan (1976-80-84) energized young conservatives and the premiership of Margaret Thatcher (1979 to 1990) overthrew a half-century of collectivism. Simultaneously, libertarian thinkers were awarded the Nobel Prize in Economics (Friedman, Hayek, Buchanan, Coase, Becker) and the Soviet system collapsed. Ashford and Davies have collected short articles into what is more properly termed an encyclopedia than a dictionary, with entries on a wide range of topics, including The Enlightenment, Race, Sociology, Utopianism, and Welfare. A list of thinkers appended to the text also provides a bibliographic reference. This book belongs on the shelf of every conservative or libertarian policymaker and should be useful to their intellectual adversaries as well.
