Nozick s justification of the minimal state Part 1 of ASU justifies the minimal state against the anarchist. This last step establishes the minimal state. So such a state is morally acceptable. Nozick s typology of distributive justice Part 2 of ASU argues against any state more extensive than the minimal state. Nozick divides them into patterned and historical , but in fact these last two are overlapping types.
Some theories are both.
The entitlement theory of justice Nozick s entitlement theory is unpatterned and historical. So the history that matters is the history of legitimate acquisition and transfer of goods. I acquire something previously unowned from the state of nature, without making others worse off overall, by occupying it. If I use labour and raw materials to which I am entitled in order to produce something, then I am entitled to that. Any other means of acquisition of goods, e.g. involuntary taxation, are unjust.
