There is no quicker means of raising a skeptical eye in some circles than to announce that one believes in both liberty and virtue. Many people who consider freedom the pre-eminent political objective perceive support for virtue to be an implicit call for restrictive new laws. More than a few advocates of virtue treat a vigorous defense of liberty as the promotion of vice. This mutual hostility is evidenced by the growing strains between many economic libertarians and social conservatives, who once submerged their differences in the pursuit of common goals. Yet neither liberty nor virtue is likely to survive alone.
