Robert Nozick is a key figure along the libertarian-right of the political spectrum and is best-known for the philosophical debate with John Rawls concerning the role of justice. Nozick sought to defend the concept of natural justice i.e. that justice is served by considering that which would occur naturally without state interference. Social justice (advocated by Rawls) however takes the opposite view and requires a degree of state intervention. Both sides of the debate claim their outlook is the fairest.

Nozick wrote widely throughout his career, but his most important work remains ‘Anarchy, the State and Utopia’
