Quintin Hogg's "The Case for Conservatism" (1947) is a classic defense of conservative principles. Hogg argues that conservatism is not simply a reaction to socialism, but a positive philosophy based on tradition, property, and the family. He also defends the role of the monarchy and the importance of local government.
Hogg's book is essential reading for anyone interested in understanding the origins of modern conservatism. It is a powerful and persuasive work that has had a lasting impact on political thought.
