Metcalf, Stephen. "The Liberty Scam: Why Even Robert Nozick Gave Up On the Movement He Inspired." SLATE June 20, 2011.

The Times Literary Supplement ranks Anarchy, published in 1974, as one of the "100 Most Influential Books Since the War," and that, I think, is underselling it. To this day, left intellectuals remember where they were when they first heard Nozick's arguments against not just socialism but wealth redistribution of any kind. "It is no exaggeration to say," the Telegraph wrote, after Nozick died in 2002, "that Nozick, more than anyone else, embodied the new libertarian zeitgeist which, after generations of statist welfarism from Roosevelt's New Deal to Kennedy, Johnson and Carter, ushered in the era of Reagan and Bush, pere et fils." Prior to Anarchy, "liberty" was a virtual synonym for rolling back labor unions and progressive taxation, a fig leaf for the class interests of the Du Ponts and the B.F. Goodriches. After Anarchy, "liberty" was a concept as worthy of academic dignity as the categorical imperative.

As a moral philosopher, Nozick was free to stretch liberty further than even an Austrian economist. That is, he was able to separate out a normative claim (that liberty is the fundamental value of values, and should be maximized) from an empirical claim (that the most efficient method for allocating goods and services is a market economy). Free to pursue liberty as a matter of pure principle, Nozick let nothing stand in his way. Should we tax the rich to feed the poor? Absolutely not, as "taxation of earnings is on par with forced labor." (Or more precisely: "Taking the earnings of n hours of labor is like taking n hours from the person.") Well, isn't at least some redistribution necessary on the basis of need? "Need a gardener allocate his services to those lawns which need him most?"

To the entire left, Nozick, in effect, said: Your social justice comes at an unacceptable cost, namely, to my personal liberty. Most distressingly, to this end Nozick enlisted the humanist's most cherished belief: the inviolability of each human being as an end unto himself—what Nozick, drawing on Immanuel Kant, calls "the separateness of persons." For Nozick, the principle of the separateness of persons is close to sacred. It affirms, as he writes, "the underlying Kantian principle that individuals are ends and not merely means; they may not be sacrificed or used for the achieving of other ends without their consent. Individuals are inviolable." . . . .
