That's what Michael Gerson, former speechwriter for President George W. Bush, writes in the Washington Post. I take a different view in my new column at the Encyclopedia Britannica Blog:
Libertarians want to live in what Adam Smith called the Great Society, the complex and productive society made possible by social interaction. We agree with George Soros that “cooperation is as much a part of the system as competition.” In fact, we consider cooperation so essential to human flourishing that we don’t just want to talk about it; we want to create social institutions that make it possible. That is what property rights, limited government, and the rule of law are all about.... The American, and libertarian, belief in freedom is not a “mania,” nor is it “selfishness.” It’s a philosophy of individual rights, the rule of law, and the institutions necessary for social cooperation. Read Locke, Hume, Smith, Tocqueville, Hayek—and yes, Rand—if you seriously believe that the philosophy of freedom can be summed up as “selfishness.”
