It was then that my mind went back all of a sudden to the kernel planted so many years before, in my island home, in the Gulf of St. Lawrence. If I become prolix over this it is only that I want to show how often it happens to parents, teachers, and others who deal with children, to throw out a thought which after lying dormant for years will become a factor in the life. Had it not been for the few words spoken then I should not, as far as I can see, now have such mastery over self as I have since attained--not very much--but I should not be writing these lines. VII My boyhood was placed in the times when Darwin's "Origin of Species" and "Descent of Man" had thrown the scientific and religious worlds into convulsion. The struggle between the old ideas and the new calls for no more than a reference here; but the teacher to whom I owe most was one who, while valuing the old, saw only an enrichment in the new, explaining the Bible in that spirit. So it happened that he spoke one day of the extraordinary ingenuity of the life-principle, which somehow came to the earth, in adapting itself to perpetually new conditions. Nothing defeated it. For millions of years it was threatened by climatic changes, by the lack of food, by the ferocity of fellow-creatures. Heat, cold, flood, drought, earthquake, and volcanic eruption were forever against it. Struggling from stage to stage upward from the slime a new danger was always to it a new incentive to finding a new resource. Pursued through the water it sought the land. Pursued on the land it sought the air. Pursued in the air it developed fleetness of wing, and in fleetness of wing a capacity for soaring, circling, balancing, dipping, and swinging on itself of which the grace must not blind us to the marvellous power of invention. In other words, the impulses leading to the origin of species proclaim a resourcefulness on the part of what we call life which we have every reason to think inexhaustible. Whatever the Fount of Being from which the life-principle first came into the waters of our earth there is no question but that with it came a conquest-principle as well. Had it been possible to exterminate the life-principle it would never have gone further than the age which saw the extinction of the great reptiles. The great reptiles went, but the life-principle stayed on, with the ability to assume, within our limited observation, all the forms between the bacillus and the elephant, while as to what lies beyond our observation the possibilities are infinite.
