“The inventor…looks upon the world and is not contented with things as they are. He wants to improve whatever he sees, he wants to benefit the world; he is haunted by an idea. The spirit of invention possesses him, seeking materialization.”

Slavery (1835)
Context: He who cannot see a brother, a child of God, a man possessing all the rights of humanity, under a skin darker than his own, wants the vision of a Christian. He worships the Outward. The spirit is not yet revealed to him. To look unmoved on the degradation and wrongs of a fellow-creature, because burned by a fiercer sun, proves us strangers to justice and love, in those universal forms which characterize Christianity.

The Philosophy of Antoninus
Context: Epictetus wanted little, and it seems that he always had the little that he wanted, and he was content with it, as he had been with his servile station. But Antoninus after his accession to the empire sat on an uneasy seat. … what must be the trials, the troubles, the anxiety, and the sorrows of him who has the world's business on his hands with the wish to do the best that he can, and the certain knowledge that he can do very little of the good which he wishes.

“But part of him wanted to say: Forget the world. He didn't want to be without her.”
