The Picture of Dorian Gray – Lord Henry Wotton

Because to influence a person is to give him one’s own soul. He does not think his natural thoughts, or burn with his natural passions. His virtues are not real to him. His sins, if there are such things as sins, are borrowed. He becomes an echo of some one else’s music, an actor of a part that has not been written for him. The aim of life is self-development. To realize one’s nature perfectly—that is what each of us is here for.
