"The microbe that might have become glorious ounces of brain has been content at first to become merely a little wart of pulp, which finds expression in skill and quickness and more of coveted leisure. There is the next higher terrace and another and another, until finally it becomes a pyramid, ever more fragile and symmetrical, the apex of which is a delicate spire, where the purest intellects are elevated to an ever increasing height in ever decreasing numbers, until in the dizzy altitude above the groveling base below they are wrapped little by little in the cold solitude of incarnate genius burning like suns with their own essence. It is so far up that the eyes deceive and men dispute who it is that stands at the top, but, whoever he may be, he has carried by the force of strength, determination and patient will, the whole swarm of his evil bacteria with him. They swarm through every terrace below, increasing in force as the pyramid enlarges downward. It is the pyramidal bulk of human nature with its finest brain, true to anatomic principles, at the top. That radiance at the summit is the delight and the aspiration of all below."
