Just as, contrary to other living beings, man has relations with his home, so he has relations with the world, and just as he has relations with his relatives, so by nature he has earnest relations with mankind. And just as he desires temporary permanence in this world, so he passionately desires immortality in the realm of eternity. And just as he strives to meet the need of his stomach for food, so he is by nature compelled to strive to provide for the stomachs of his mind, heart, spirit, and humanity. He has such hopes and desires that nothing apart from eternal happiness can satisfy them.
