“They say that none of us exists, except in the imagination of his fellows, other than as an intangible, invisible mentality.”

“We are, all of us, creatures of habit, and when the seeeming necessity for schooling ourselves in new ways ceases to exist, we fall naturally and easily into the manner and customs which long usage has implanted ineradicably within us.”

“My mind is evidently so constituted that I am subconsciously forced into the path of duty without recourse to tiresome mental processes.”

“Imagine, if you can, a huge grizzly with ten legs armed with mighty talons and an enormous froglike mouth splitting his head from ear to ear, exposing three rows of long, white tusks. Then endow this creature of your imagination with the agility and ferocity of a half-starved Bengal tiger and the strength of a span of bulls, and you will have some faint conception of Woola in action.”

“Imagination is but another name for super intelligence.”

“[The little black boy] had seen Tarzan bring down a buck, just as Numa, the lion, might have done... Tibo had shuddered at the sight, but he had thrilled, too, and for the first time there entered his dull, Negroid mind a vague desire to emulate his savage foster parent. But Tibo, the little black boy, lacked the divine spark which had permitted Tarzan, the white boy, to benefit by his training in the ways of the fierce jungle. In imagination he was wanting, and imagination is but another name for super-intelligence.Imagination it is which builds bridges, and cities, and empires. The beasts know it not, the blacks only a little, while to one in a hundred thousand of earth's dominant race it is given as a gift from heaven that man may not perish from the earth.”

“Like its master, it was entirely devoid of hair, but was of a dark slate color and exceeding smooth and glossy. Its belly was white, and its legs shaded from the slate of its shoulders and hips to a vivid yellow at the feet. The feet themselves were heavily padded and nailless, which fact had also contributed to the noiselessness of their approach, and, in common with a multiplicity of legs, is a characteristic feature of the fauna of Mars. The highest type of man and one other animal, the only mammal existing on Mars, alone have well-formed nails, and there are absolutely no hoofed animals in existence there.”
