“Nature” and “Grace” have been contrasted with each other in a way not very respectful to the Divine omnipotence. Kings and queens reign “by the Grace of God,” but a sweet, docile, pious disposition, such as is born in some children and grows up with them,--that congenital gift which good Bishop Hall would look for in a wife,--is attributed to “Nature.” In fact “Nature” and “Grace,” as handled by the scholastics, are nothing more nor less than two hostile Divinities in the Pantheon of post-classical polytheism. What is the secret of the profound interest which “Darwinism” has excited in the minds and hearts of more persons than dare to confess their doubts and hopes? It is because it restores “Nature” to its place as a true divine manifestation. It is that it removes the traditional curse from that helpless infant lying in its mother's arms. It is that it lifts from the shoulders of man the responsibility for the fact of death. It is that, if it is true, woman can no longer be taunted with having brought down on herself the pangs which make her sex a martyrdom. If development upward is the general law of the race; if we have grown by natural evolution out of the cave-man, and even less human forms of life, we have everything to hope from the future. That the question can be discussed without offence shows that we are entering on a new era, a Revival greater than that of Letters, the Revival of Humanity. The prevalent view of “Nature” has been akin to that which long reigned with reference to disease. This used to be considered as a distinct entity apart from the processes of life, of which it is one of the manifestations. It was a kind of demon to be attacked with things of odious taste and smell; to be fumigated out of the system as the evil spirit was driven from the bridal-chamber in the story of Tobit. The Doctor of earlier days, even as I can remember him, used to exorcise the demon of disease with recipes of odor as potent as that of the angel's diabolifuge,--the smoke from a fish's heart and liver, duly burned,--“the which smell when the evil spirit had smelled he fled into the uttermost parts of Egypt.” The very moment that disease passes into the category of vital processes, and is recognized as an occurrence absolutely necessary, inevitable, and as one may say, normal under certain given conditions of constitution and circumstance, the medicine-man loses his half-miraculous endowments. The mythical serpent is untwined from the staff of Esculapius, which thenceforth becomes a useful walking-stick, and does not pretend to be anything more.
