"They should have slain you easily," said Ghek. "So great and highly developed is the power of reason among us that they should have known before you struck just where, logically, you must seek to strike, and so they should have been able to parry your every thrust and easily find an opening to your heart." "But they did not, Ghek," Gahan reminded him. "Their theory of development is wrong, for it does not tend toward a perfectly balanced whole. You have developed the brain and neglected the body and you can never do with the hands of another what you can do with your own hands. Mine are trained to the sword--every muscle responds instantly and accurately, and almost mechanically, to the need of the instant. I am scarcely objectively aware that I think when I fight, so quickly does my point take advantage of every opening, or spring to my defense if I am threatened that it is almost as though the cold steel had eyes and brains. You, with your kaldane brain and your rykor body, never could hope to achieve in the same degree of perfection those things that I can achieve. Development of the brain should not be the sum total of human endeavor. The richest and happiest peoples will be those who attain closest to well-balanced perfection of both mind and body, and even these must always be short of perfection. In absolute and general perfection lies stifling monotony and death. Nature must have contrasts; she must have shadows as well as highlights; sorrow with happiness; both wrong and right; and sin as well as virtue." "Always have I been taught differently," replied Ghek; "but since I have known this woman and you, of another race, I have come to believe that there may be other standards fully as high and desirable as those of the kaldanes. At least I have had a glimpse of the thing you call happiness and I realize that it may be good even though I have no means of expressing it. I cannot laugh nor smile, and yet within me is a sense of contentment when this woman sings--a sense that seems to open before me wondrous vistas of beauty and unguessed pleasure that far transcend the cold joys of a perfectly functioning brain. I would that I had been born of thy race." Caught by a gentle current of air the flier was drifting slowly toward the northeast across the valley of Bantoom. Below them lay the cultivated fields, and one after another they passed over the strange towers of Moak and Nolach and the other kings of the swarms that inhabited this weird and terrible land. Within each enclosure surrounding the towers grovelled the rykors, repellent, headless things, beautiful yet hideous.
