“There will be a new church founded on moral science, at first cold and naked, a babe in a manger again, the algebra and mathematics of ethical law, the church of men to come, without shams, or psaltery, or sackbut; but it will have heaven and earth for its beams and rafters; science for symbol and illustration; it will fast enough gather beauty, music, picture, poetry. Was never stoicism so stern and exigent as this shall be. It shall send man home to his central solitude, shame these social, supplicating manners, and make him know that much of the time he must have himself to his friend. He shall expect no cooperation, he shall walk with no companion..”
~ Ralph Waldo Emerson ~
U.S. essayist, poet, philosopher
