They have consoled the hero's widow and are educating his orphans. They have erected a monument to enlightened charity to which time can add only grandeur. There is much, however, to be accomplished still. Slavery has been abolished, but Progress requires more. We are called upon to make this a free government in the broadest sense, to give liberty to all. Standing in the presence of all history, knowing the experience of mankind, knowing that the earth is covered with countless wrecks of cruel failures; appealed to by the great army of martyrs and heroes who have gone before; by the sacred dust filling innumerable graves; by the memory of our own noble dead; by all the suffering of the past; by all the hopes for the future; by all the glorious dead and the countless millions yet to be, I pray, I beseech, I implore the American people to lay the foundation of the Government upon the principles of eternal justice. I pray, I beseech, I implore them to take for the corner-stone, Universal Human Liberty--the stone which has been heretofore rejected by all the builders of nations. The Government will then stand, and the swelling dome of the temple will touch the stars. CONCLUSION I HAVE thus endeavored to show you some of the effects of slavery, and to prove to you that a step in order to be in the direction of progress must be in the direction of freedom; that slavery either of body or mind is barbarism and is practiced and defended only by infamous tyrants or their dupes. I have endeavored to point out some of the causes of the abolition of slavery, both of body and mind. There is one truth, however, that you must not forget, and that is, that every evil tends to correct and abolish itself. I believe, however, that the diffusion of knowledge, more than everything else combined, has ameliorated the condition of mankind. When there was no freedom of speech and no press, then every idea perished in the brain that gave it birth. One man could not profit by the thought of another. The experience of the past was in a great degree unknown. And this state of things produced the same effect in the mental world, that confining all the water to the springs would in the physical. Confine the water to the springs, the rivulets would cease to murmur, the rivers to flow, and the ocean itself would become a desert of sand. But with the invention of printing, ideas began to circulate, born of the busy brain of the million--little rivulets of facts running into rivers of information, and they all flowing into the great ocean of human knowledge.
