Human Action: A Treatise on Economics is the most important book on political economy you will ever own. It was (and remains) the most comprehensive, systematic, forthright, and powerful defense of the economics of liberty ever written. This is the Scholars Edition: accept no substitute. You will treasure this volume.
The Scholars Edition is the original, unaltered treatise (originally published in 1949) that shaped a generation of Austrians and made possible the intellectual movement that is leading the global charge for free markets.
