property
A more extended exposition of the origins of property rights is presented by Rousseau in On Social Contract, Book I, Chap. 9. Although the act of association legitimates private property, by that very act individual rights also become subordinate to collective rights.
But such laws must be general. Under Lycurgus' laws the property of all the Spartans was redistributed to the people. Under Solon, in contrast, all debts were eliminated, thus discriminating against the rich.
