The Immunity Code

In recent years, libertarian impulses have increasingly influenced national and economic debates, from welfare reform to efforts to curtail affirmative action. Murray N. Rothbard's classic The Ethics of Liberty stands as one of the most rigorous and philosophically sophisticated expositions of the libertarian political position.

What distinguishes Rothbard's book is the manner in which it roots the case for freedom in the concept of natural rights and applies it to a host of practical problems. An economist by profession, Rothbard here proves himself equally at home with philosophy. And while his conclusions are radical—that a social order that strictly adheres to the rights of private property must exclude the institutionalized violence inherent in the state—his applications of libertarian principles prove surprisingly practical for a host of social dilemmas, solutions to which have eluded alternative traditions.

It follows a narrative, going from one stage to the next, and it largely happens by trial and error—a version of natural selection. Much of the human world is the result of human action but not of human design: it emerges from the interactions of millions, not from the plans of a few.

Drawing on fascinating evidence from science, economics, history, politics, and philosophy, Matt Ridley demolishes conventional assumptions that the great events and trends of our day are dictated by those on high. On the contrary, our most important achievements develop from the bottom up. The Industrial Revolution, cell phones, the rise of Asia, and the Internet were never planned; they happened. Languages emerged and evolved by a form of natural selection, as did common law. Torture, racism, slavery, and pedophilia—all once widely regarded as acceptable—are now seen as immoral despite the
