Answer:
Although Robert Nozick did not consider himself to be primarily a political philosopher, he is best known for his contributions to it. Undoubtedly, Nozick’s work in epistemology and metaphysics (especially with respect to free will and the “closest continuer” theory of personal identity) has had a significant impact on those fields. However, it was the publication of his first book, Anarchy, State and Utopia (1974) that revitalized the political right-wing and set off a firestorm of critical replies and commentaries. While Nozick’s accomplishments reach far beyond the confines of political philosophy, it is safe to say that most recognize him for his work on attempting to provide a justification for the state, setting the limits of government, and trying to convince us that accepting his minimal state could foster a framework for a constellation of communities constituting a sort of utopia.
Anarchy, State and Utopia can also be seen as a critical response to John Rawls’ Theory of Justice, which was published just three years earlier and was considered to be the most robust and sophisticated defense of liberal egalitarianism. Although many credit Rawls for single-handedly rekindling interest in political philosophy, this is likely overstated praise. There is little doubt that Nozick’s systematic criticism of Rawls’ theory of justice and establishment of a rival political theory in Anarchy, State and Utopia also played a major role in bring significant attention back to political philosophy.
