The right of the first occupier, though more real than the right of the strongest, becomes a real right only when the right of property has already been established. Every man has naturally a right to everything he needs; but the positive act which makes him proprietor of one thing excludes him from everything else. Having his share, he ought to keep to it, and can have no further right against the community. This is why the right of the first occupier, which in the state of nature is so weak, claims the respect of every man in civil society. In this right we are respecting not so much what belongs to another as what does not belong to ourselves.

In general, to establish the right of the first occupier over a plot of ground, the following conditions are necessary: first, the land must not yet be inhabited; secondly, a man must occupy only the amount he needs for his subsistence; and, in the third place, possession must be taken, not by an empty ceremony, but by labour and cultivation, the only sign of proprietorship that should be respected by others, in default of a legal title.
