So it is of the greatest importance that the inventions of the world should be brought beneath one roof. These inventions, in my judgment, are destined to be the liberators of mankind. They enslave forces and compel the energies of nature to work for man. These forces have no backs to feel the lash, no tears to shed, no hearts to break. The history of the world demonstrates that man becomes What we call civilized by increasing his wants. As his necessities increase, he becomes industrious and energetic. If his heart does not keep pace with his brain, he is cruel, and the physically or mentally strong enslave the physically or mentally weak. At present these inventions, while they have greatly increased the countless articles needed by man, have to a certain extent enslaved mankind. In a savage state there are few failures. Almost any one succeeds in hunting and fishing. The wants are few, and easily supplied. As man becomes civilized, wants increase; or rather as wants increase, man becomes civilized. Then the struggle for existence becomes complex; failures increase. The first result of the invention of machinery has been to increase the wealth of the few. The hope of the world is that through invention man can finally take such advantage of these forces of nature, of the weight of water, of the force of wind, of steam, of electricity, that they will do the work of the world; and it is the hope of the really civilized that these inventions will finally cease to be the property of the few, to the end that they may do the work of all for all. When those who do the work own the machines, when those who toil control the invention, then, and not till then, can the world be civilized or free. When these forces shall do the bidding of the individual, when they become the property of the mechanic instead of the monopoly, when they belong to labor instead of what is called capital, when these great powers are as free to the individual laborer as the air and light are now free to all, then, and not until then, the individual will be restored and all forms of slavery will disappear. Another great benefit will come from the Fair. Other nations in some directions are more artistic than we, but no other nation has made the common as beautiful as we have. We have given beauty of form to machines, to common utensils, to the things of every day, and have thus laid the foundation for producing the artistic in its highest possible forms. It will be of great benefit to us to look upon the paintings and marbles of the Old World. To see them is an education. The great Republic has lived a greater poem than the brain and heart of man have as yet produced, and we have supplied material for artists and poets yet unborn; material for form and color and song. The Republic is to-day Art's greatest market. Nothing else is so well calculated to make friends of all nations as really to become acquainted with the best that each has produced.
