This document summarizes Robert Nozick's libertarian theory of entitlement as presented in his book "Anarchy, State, and Utopia." Nozick argued for a minimal state limited to protecting individuals' basic rights and liberties. He rejected redistribution of wealth and advocated for a free market where individuals acquire property through just means like work or exchange. Nozick believed as long as transactions respect people's rights, patterns of holdings are just, even if they result in significant inequalities. The document outlines Nozick's views on natural rights like life and property, the principles of just acquisition and transfer of holdings, and criticisms of his theory.
