When we look at the world today and at the condition it is in, we begin to wonder if we understand any better than those who lived before us the idea that life is an opportunity. In spite of our present stage of evolution and the scientific advancement of the world, the war which humanity went through not long ago shows that never in the history of the world was such a great catastrophe caused by mankind. It seems as though the whole evolution of humanity had been intended to prepare and to create such means of destruction that the greater part of humanity has been ruined by it. And when we think of the distrust that exists today among nations and how one nation has allowed another nation to be ruined, we begin to feel that we understand the idea much less than those who lived before us that life is an opportunity.
