Philo Judaeus Quod Deus Sit Immutabilis 19

[19] And altogether these persons are to be detested who beget children for themselves, that is to say, who, pursuing their own private advantage alone, disregard all other objects, as if they had been born for themselves alone, and not for ten thousand other persons also, for their fathers, and their mothers, and their wives, and their children, and their country, and for all mankind. And if we must go further and add any thing to this enumeration, we may say for heaven, and earth, and the whole universe, and for the sciences, and for the virtues, and for the Father and Ruler of all; to every one of which a man ought to pay what is due to the best of his power, not looking upon all the world as an addition to himself, but on himself as an addition to the rest of the world. ¹
