If more is given to the better man than to the worse, that is because, in the long run, the general happiness is increased by rewarding virtue and punishing vice, not because of an ultimate ethical doctrine that the good deserve more than the bad.

Context

““justice” as “equality”: when two men’s interests clash, the right course is that which produces the greatest total of happiness, regardless of which of the two enjoys it, or how it is shared among them. If more is given to the better man than to the worse, that is because, in the long run, the general happiness is increased by rewarding virtue and punishing vice, not because of an ultimate ethical doctrine that the good deserve more than the bad. “Justice,” in this view, consists in considering only the amount of happiness involved, without favour to one individual or class as against another. Greek philosophers, including Plato and Aristotle, had a different conception of justice, and it is one which is still widely prevalent.” source
