"The human race may be compared to a writer. At the outset a writer has often only a vague general notion of the plan of his work, and of the thought he intends to elaborate. As he proceeds, penetrating his material, laboring to express himself fitly, he lays a firmer grasp on his thought; he finds himself. So the human race is writing its story, finding itself, discovering its own underlying purpose, revising, recasting a tale pathetic often, yet none the less sublime."
