""I do not understand exactly what you mean by fear," said Tarzan. "Like lions, fear is a different thing in different men, but to me the only pleasure in the hunt is the knowledge that the hunted thing has power to harm me as much as I have to harm him. If I went out with a couple of rifles and a gun bearer, and twenty or thirty beaters, to hunt a lion, I should not feel that the lion had much chance, and so the pleasure of the hunt would be lessened in proportion to the increased safety which I felt."

"Then I am to take it that Monsieur Tarzan would prefer to go naked into the jungle, armed only with a jackknife, to kill the king of beasts," laughed the other good naturedly, but with the merest touch of sarcasm in his tone.

"And a piece of rope," added Tarzan."

"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."
— Edgar Rice Burroughs (The Beasts of Tarzan)

"As the body rolled to the ground Tarzan of the Apes placed his foot upon the neck of his lifelong enemy and, raising his eyes to the full moon, threw back his fierce young head and voiced the wild and terrible cry of his people."
— Edgar Rice Burroughs (Tarzan of the Apes)

"The time has arrived when patience becomes a crime and mayhem appears garbed in a manner of virtue"

"For myself, I always assume that a lion is ferocious, and so I am never caught off my guard."
— Edgar Rice Burroughs (Tarzan of the Apes)

"[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."
