On Nozick, Edward Feser’s excellent new primer on Anarchy, State, and Utopia (1974), puts Nozick’s classic of political philosophy in historical perspective and relates it to other libertarian rights theories. Although it glosses over several nuances of Nozick’s theory and occasionally fails to state when a point is Feser’s own, these imperfections pale before the book’s virtues—its accuracy, insightfulness, and uncommonly sympathetic (but not uncritical) enthusiasm for Nozick’s enterprise.
