Mill on the Institution of Property
From Principles of Political Economy, p155-156:
We proceed, then, to the consideration of the different modes of distributing the produce of land and labor, which have been adopted in practice, or may be conceived in theory. Among these, our attention is first claimed by that primary and fundamental institution, on which, unless in some exceptional and very limited cases, the economical arrangements of society have always rested, though in its secondary features it has varied, and is liable to vary. I mean, of course, the institution of individual property.
Private property, as an institution, did not owe its origin to any of those considerations of utility which plead for the maintenance of it when established. Enough is known of rude ages, both from history and from analogous states of society in our own time, to show that tribunals (which always precede laws) were originally established, not to determine rights, but to repress violence and terminate quarrels. With this object chiefly in view, they naturally enough gave legal effect to first occupancy, by treating as the aggressor the person who first commenced violence, by turning, or attempting to turn, another out of possession.
