Nozick on Locke’s Theory of Acquisition, the Lockean Proviso, and Collective Assets

Locke’s Theory of Acquisition
Nozick’s goal in this section of AS&U is to, in his words, “introduce an additional bit of complexity into the structure of the entitlement theory.” To do this, he uses as a starting point Locke’s approach to justice in property acquisition—namely, that ownership of an object originates in one’s mixing of labor with that object. Nozick then proceeds to ask the standard gamut of questions calling attention to some difficulties in Locke’s theory of acquisition, like whether dumping a can of tomato juice in the ocean constitutes “mixing one’s labor” with the ocean. Essentially, the questions seek the strict boundary between what constitutes a mixing of labor sufficient for just acquisition and what does not. Under the Lockean notion of acquisition, it seems that one naïve interpretation would say that improving upon an object entails full ownership of the object. Of course, as Nozick points out, if the stock of improvable unowned objects is limited, this view is unfeasible. He uses the appropriation of a grain of sand as an example of one’s appropriation removing another’s liberty (as Hohfeld uses the word) to act on a previously unowned object, but intuitively suggests that this particular removal is not problematic. The central concern, he says, “is whether appropriation of an unowned object worsens the situation of others.”
