"Behind every man now alive stand thirty ghosts, for that is the ratio by which the dead outnumber the living."

Man—every man—is an end in himself, not a means to the ends of others; he must live for his own sake, neither sacrificing himself to others nor sacrificing others to himself; he must work for his rational self-interest, with the achievement of his own happiness as the highest moral purpose of his life.
