Robert Nozick

"Taxation of earnings from labor is on a par with forced labor. Seizing the results of someone's labor is equivalent to seizing hours from him and directing him to carry on various activities." 

Robert Nozick (November 16, 1938 – January 23, 2002) was an American philosopher. He held the Joseph Pellegrino University Professorship at Harvard University, and was president of the American Philosophical Association. He is best known for his books "Anarchy, State, and Utopia" (1974), a libertarian answer to John Rawls' "A Theory of Justice" (1971), in which Nozick also presented his own theory of utopia as one in which people can freely choose the rules of the society they enter into, and "Philosophical Explanations" (1981), which included his counterfactual theory of knowledge.
