No one man devised this solution, but many superior minds contributed to it. It is mankind's greatest cumulative discovery. It is only concealed from most eyes because it transforms gradually instead of swiftly. It can increase man's inner resources until he is not only equal to the gigantic biological tasks facing him, but is able to go on to better things. One of the several names for this solution, the logical successor to natural selection, is intelligent selection.
Man is young as species go.
He doesn't have to accept senility and decline as inevitable. Already he has within his grasp the knowledge to make himself a better man than his forebears. Intelligent selection gives him the remarkable opportunity to control his own evolution. Or he may utilize the constructive evolutionary powers which great minds have placed in his hand. Whether he uses or rejects his new opportunities will determine whether his future trends upward or downward.
