In short, if labor and production are the principle of the right of property, the fact of first occupancy is its indispensable condition.
"4.

I possess legitimately: then I have the right to use my property as I see fit.

I have also the right to give it away.

I have also the right to bequeath it; for if I decide to make a donation, my decision is as valid after my death as during my life." In fact, to become a proprietor, in M.Cousin's opinion, one must take possession by occupation and labor.

I maintain that the element of time must be considered also; for if the first occupants have occupied every thing, what are the new comers to do?
What will become of them, having an instrument with which to work, but no material to work upon?
Must they devour each other?
A terrible extremity, unforeseen by philosophical prudence; for the reason that great geniuses neglect little things.
Notice also that M.Cousin says that neither occupation nor labor, taken separately, can legitimate the right of property; and that it is born only from the union of the two.
