The Second Virtue: Justice

The first office of justice is to keep one man from doing harm to another, unless provoked by wrong ;
and the next is to lead men to use common possessions for the common interests, private property for their own.
There is, however, no such thing as private ownership established by nature, but property becomes private either through long occupancy (as in the case of those who long ago settled in unoccupied territory) or through conquest (as in the case of those who took it in war) or by due process of law, bargain, or purchase, or by allotment.
