It is better if each minds his own business. Property should be private, but people should be so trained in benevolence as to allow the use of it to be largely common. Benevolence and generosity are virtues, and without private property they are impossible.

Context

“It is essential to the carrying out of Plato’s plans, but it is certainly not more impossible than many other things that he recommends.
Plato’s communism annoys Aristotle. It would lead, he says, to anger against lazy people, and to the sort of quarrels that are common between fellow-travellers. It is better if each minds his own business. Property should be private, but people should be so trained in benevolence as to allow the use of it to be largely common. Benevolence and generosity are virtues, and without private property they are impossible. Finally we are told that, if Plato’s plans were good, someone would have thought of them sooner.* I do not agree with Plato, but if anything could make me do so, it would be Aristotle’s arguments against him.
