“There is such a thing as anesthesia of pain, engendered by pain too exquisite to be borne. ”

“No; I did not hate him. The word is too weak. There is no word in the language strong enough to describe my feelings. I can say only that I knew the gnawing of a desire for vengeance on him that was a pain in itself and that exceeded all the bounds of language. ”

“It was a pain and an unrest; and it received easement only by the touch of the new god's presence. At such times love was joy to him, a wild, keen–thrilling satisfaction. But when away from his god, the pain and the unrest returned; the void in him sprang up and pressed against him with its emptiness, and the hunger gnawed and gnawed unceasingly.”

“Life is a strange thing. Why this longing for life? It is a game which no man wins. To live is to toil hard and to suffer sore, till old age creeps heavily upon us and we throw down our hands on the cold ashes of dead fires. It is hard to live. In pain the babe sucks his first breath, in pain the old man gasps his last, and all his days are full of trouble and sorrow; yet he goes down to the open arms of death, stumbling, falling, with head turned backward, fighting to the last. And death is kind. It is only life and the things of life that hurt. Yet we love life and we hate death. It is very strange.”

And that he should be stirred by it marked the completeness with which he harked back through the ages of fire and roof to the raw beginnings of life in the howling ages.”

“Of her own experience she had no memory of the thing happening; but in her instinct, which was the experience of all mothers of wolves, there lurked a memory of fathers that had eaten their new-born and helpless progeny.”

“In the height of the gusts, in my high position, where the seas did not break, I found myself compelled to cling tightly to the rail to escape being blown away. My face was stung to severe pain by the high-driving spindrift, and I had a feeling that the wind was blowing the cobwebs out of my sleep-starved brain. ”
