"The most rigid laws were passed in regard to the practice of medicine. No physician could become a practitioner until examined and authorized to do so by the State Medical College. In order to prevent favoritism, or the furnishing of diplomas to incompetent applicants, enormous penalties were incurred by any who would sign such. The profession long ago became extinct. Every mother is a family physician. That is, she obeys the laws of nature in regard to herself and her children, and they never need a doctor.
"Having become healthy and independent of charity, crime began to decrease naturally. The conditions that had bred and fostered petty crimes having ceased to exist, the natures that had inherited them rose above their influence in a few generations, and left honorable posterity.
"But crime in its grossest form is an ineradicable hereditary taint. Generation after generation may rise and disappear in a family once tainted with it, without displaying it, and then in a most unexpected manner it will spring up in some descendant, violent and unconquerable.
"We tried to eliminate it as we had disease, but failed. It was an inherited molecular structure of the brain. Science could not reconstruct it. The only remedy was annihilation. Criminals had no posterity."
"I am surprised," I interrupted, "that possessing the power to control the development of the body, you should not do so with the mind."
"If we could we would produce genius that could discover the source of all life. We can control Cause and Effect, but we cannot create Cause. We do not even know its origin. What the perfume is to the flower, the intellect is to the body; a secret that Nature keeps to herself. For a thousand years our greatest minds have sought to discover its source, and we are as far from it to-day as we were a thousand years ago."
"How then have you obtained your mental superiority?" I inquired.
"By securing to our offspring perfect, physical and mental health. Science has taught us how to evolve intellect by following demonstrated laws. I put a seed into the ground and it comes up a little green slip, that eventually becomes a tree. When I planted the seed in congenial soil, and watered and tended the slip, I assisted Nature. But I did not create the seed nor supply the force that made it develop into a tree, nor can I define that force."
"What has produced the exquisite refinement of your people?"
