What do we mean by Conservatism? The 20th century saw Conservatism go from New Deal outcast to post-World War II respectability through insurgency with William Buckley and Barry Goldwater, to the governance of Margaret Thatcher and Ronald Reagan. This lecture will explore Conservatism’s storied history from Edmund Burke’s Reflections on the Revolution in France, to America’s founding and Constitution, and Adam Smith’s Wealth of Nations. Contributions from social science, economics, literature, politics, Roman Catholicism, law, and philosophy will be examined. Discussion will include conservative principles and today’s conservative platform. Alternatives such as libertarianism, neoconservativism, and Trumpism will be addressed, as will prospects for the 21st century.
