Every living being on earth loves life above all else. The smallest insect, whose life lasts only an instant, tries to escape from any danger in order to live a moment longer. And the desire to live is most awakened in man. As intelligence wakens in man, he begins to wonder whether life is merely transitory, and if, after this life, all is ended. To him the thought that after his short life the world will end is more terrible than death. And if life had not an intoxicating effect, this thought would kill many people. The man who thinks that after this life there is nothing more, cannot dwell very long on that thought. Dwelling on this thought and contemplating upon it is like what a man feels who is standing on a great height and looks down -- it terrifies him.
