Then there is another kind of doubt against which you should beware. There are certain doubts that, if accepted and acted on, stand in the way of the creation of the most magnificent facts in the world. Take as an illustration of what I mean: when Napoleon, a young man in Paris, was asked to take command of the guard of the city, suppose he had doubted, questioned, distrusted, his own ability; suppose he had been timid and afraid, the history of the world would have been changed by that one doubt. Take another illustration. At the opening of our war or in the months just preceding the beginning of active hostilities the man then occupying the presidential chair had no faith, no faith in himself, no faith in the perpetuity of our institutions, no faith in the people; and so he sat doubting, while everything crumbled in pieces around him. And then appeared a man in whom the people had little faith at first, and who had no great faith perhaps in his own ability; but he had infinite faith in God, faith in right, faith in the people, faith in the possibilities of freedom trusted in the hands of the people. And this faith created a new nation. If there had been doubt in the heart of Abraham Lincoln, again the history of the world would have been &hanged. He believed that "Right is right, since God is God, And right the day must win: To doubt would be disloyalty, To falter would be sin." You see, then, here is another field where you had better be wary of doubt. Do not doubt yourself, do not doubt the possibilities of noble action, noble character, of achievement. We say of a young man entering life, brimful of enthusiasm, that all this will be toned down by and by; and we speak of it as though the enthusiasm itself somehow was a fault or a folly. And yet it is just this enthusiasm of the young men that moves and lifts the world. It is this faith in themselves and in the possibility of great things, it is this faith that lies at the heart of every invention, of every great discovery, of every magnificent achievement. Read the history of invention. The world is full of stories of men who got a new idea. They were laughed at, they were told it was impracticable; and, if they had been laughed out of it, it would have been impracticable. It was their faith in the possibility of some great new thing, their faith in the resources of the universe, their faith in themselves as able to discover some new truth and make it applicable to the needs of the world, it was this faith which has been at the root of the grandest things that have ever been done. It is this which was in the heart of Columbus as he sailed out towards the West. It is this which was in the heart of Magellan as he studied the shadow of the earth across the face of the moon, and believed in the story that shadow told him against the constituted authorities of the world.
