Good reads on natural law, Lockean liberalism, & equality

Walter Lippmann stampA few people recently asked me for some good reads to start them into natural law, Lockean liberalism, and the equality clause. I oblige them here.

The Teaching Company’s Great Courses includes a thoughtful overview on the history and development of natural law theory. Joseph Koterski’s “Natural Law and Human Nature” course comes with a good “course guidebook” that has lots of suggestions for more reading.

One of those suggestions is Paul E. Sigmund’s book Natural Law in Political Thought. Here is the most approachable scholarly book I’ve read on the subject. Like Koterski’s course, Sigmund’s book traces natural law’s development over the centuries.

Sigmund’s book, in turn, mentions Walter Lippmann’s book The Public Philosophy. I’m reading it now. Unlike Koterski and Sigmund, Lippmann was not a scholar but (as Wikipedia puts it) a public intellectual and an amateur philosopher. He wrote The Public Philosophy in 1955, near the end of his reign as probably the twentieth century’s most influential American columnist. Lippmann’s book isn’t a history book; instead, it advocates that America readopt natural law as its public philosophy.

Another well-argued piece is political science professor Harry V. Jaffa’s 1987 law review article “What Were the ‘Original Intentions’ of the Framers of the Constitution of the United States?” Jaffa takes issue with his fellow conservatives who reject natural law in favor of strict constructionism. (If you click the above link to that article, be prepared to be patient. It takes a while to load.) Jaffa’s shorter article along those same lines is “The False Prophets of American Conservatism.” If you end up liking Jaffa and want to challenge yourself, treat yourself to what I consider to be the past few decades’ greatest work of American political science, A New Birth of Freedom: Abraham Lincoln and the Coming of the Civil War, published in 2000. In it, Jaffa develops the founders’ and Lincoln’s political philosophy and establishes the significance of the equality clause and the natural-law hierarchy it reinforces among God, mankind, and nature. Very slow, difficult, but rewarding reading.  (You can read my customer review of the book here.)

Three good primary sources would be Locke’s Second Treatise on Government, Hamilton, Madison, and Jay’s Federalist Papers, and Lincoln’s writings. Political Writings of John Locke has a long (115 pages) and excellent introduction by David Wootton. The introduction puts Locke’s works in the context of his life and times and explains his works’ appeal to the American revolutionary generation. The Signet Classic version of the Federalist Papers has a much shorter but equally thoughtful introduction, this one by Charles R. Kesler. Written in 1999, the introduction presciently demonstrates how pertinent the Federalist Papers are to us today: “The American Union is threatening to split up into separate confederacies of states, Publius argues, and each state is itself teetering on the brink of tyranny due to the danger of majority faction.” As for Lincoln’s writings, I use Lincoln on Democracy, edited by Mario M. Cuomo and Harold Holzer, and the Holzer-edited version of the Lincoln-Douglas debates. My favorite intellectual biography of Lincoln is the very approachable Abraham Lincoln: Redeemer President by Allen C. Guelzo.

Two other books I’ve read should not be missed: Alexander S. Rosenthal’s Crown Under Law: Richard Hooker, John Locke, and the Ascent of Modern Constitutionalism and Ruth W. Grant’s John Locke’s Liberalism. The links associated with those titles lead to my extensive reviews of the titles.

Three good steps for finding free or cheap books: (1) showroom Amazon (many would say it’s only fair) using its customer reviews and its “Look Inside” feature where available, or Google Books, to see what you want, (2) look for free e-book downloads on’s texts sectionOpen Library, or Amazon’s Kindle store and the like (usually books out of copyright) (you can borrow many e-books at these sites, too), and, barring that, (3) shop for used hard-copy books, starting at bookfinder.comAnd three guidelines for buying used books: (1) hardbacks are often way cheaper than paperbacks, (2) older editions are often way cheaper than newer editions, and (3) (contrary to all reason) well-marked books are often way cheaper than “clean” books.

I can’t compile such a digest of political science books as this without acknowledging the work that got me interested in natural law, Lockean liberalism, and the equality clause more than a quarter-century ago: Jaffa’s Crisis of the House Divided: An Interpretation of the Issues in the Lincoln-Douglas Debates. I trembled, reading it the first time.
