I see the unity of thought and of morals running through all animated Nature; there is no difference of quality, but only of more and less. The animal who is wholly kept down in Nature has no anxieties. By yielding, as he must do, to it, he is enlarged and reaches his highest point. The poor grub, in the hole of a tree, by yielding itself to Nature, goes blameless through its low part and is rewarded at last, casts its filthy hull, expands into a beautiful form with rainbow wings, and makes a part of the summer day. The Greeks called it Psyche, a manifest emblem of the soul. The man down in Nature occupies himself in guarding, in feeding, in warming and multiplying his body, and, as long as he knows no more, we justify him; but presently a mystic change is wrought, a new perception opens, and he is made a citizen of the world of souls: he feels what is called duty; he is aware that he owes a higher allegiance to do and live as a good member of this universe. In the measure in which he has this sense he is a man, rises to the universal life. The high intellect is absolutely at one with moral nature. A thought is imbosomed in a sentiment, and the attempt to detach and blazon the thought is like a show of cut flowers. The moral is the measure of health, and in the voice of Genius I hear invariably the moral tone, even when it is disowned in words;--health, melody and a wider horizon belong to moral sensibility. The finer the sense of justice, the better poet. The believer says to the skeptic:-- “One avenue was shaded from thine eyes Through which I wandered to eternal truth.” Humility is the avenue. To be sure, we exaggerate when we represent these two elements as disunited; every man shares them both; but it is true that men generally are marked by a decided predominance of one or of the other element. In youth and in age we are moralists, and in mature life the moral element steadily rises in the regard of all reasonable men. ’Tis a sort of proverbial dying speech of scholars (at least it is attributed to many) that which Anthony Wood reports of Nathaniel Carpenter, an Oxford Fellow. “It did repent him,” he said, “that he had formerly so much courted the maid instead of the mistress” (meaning philosophy and mathematics to the neglect of divinity). This, in the language of our time, would be ethics. And when I say that the world is made up of moral forces, these are not separate. All forces are found in Nature united with that which they move: heat is not separate, light is not massed aloof, nor electricity, nor gravity, but they are always in combination. And so moral powers; they are thirsts for action, and the more you accumulate the more they mould and form.
