Voted one of Christianity Today's 1998 Books of the Year!With uninterrupted clarity, frequent eloquence and occasional humor, J. Budziszewski presents and defends the natural law tradition in what is at once a primer for students and a vigorous argument for scholars.Written on the Heart expounds the work of the leading architects of theory on natural law, including Aristotle, Thomas Aquinas and John Locke. It also takes up contemporary philosophy, theology and political science, colorfully running against the intimidating tide of advanced pluralism that finds natural law so difficult to tolerate.Throughout the volume, Budziszewski sure-footedly achieves his self-confessed aim of displaying the "subtlety, richness and intellectual surprise" of the natural law tradition.
