Context

“Well then, for a man to take something from his neighbour and to profit by his neighbour's loss is more contrary to Nature than is death or poverty or pain or anything else that can affect either our person or our property. For, in the first place, injustice is fatal to social life and fellowship between man and man. For, if we are so disposed that each, to gain some personal profit, will defraud or injure his neighbour, then those bonds of human society, which are most in accord with Nature's laws, must of {22} necessity be broken.” source
