Man is man because he chanced to develop intelligence instead of instinct; otherwise he would to this day have remained among the anthropoid apes. He has turned away from nature, become unnatural, as it were, disliked the earth upon which he found himself, and changed the face of it somewhat to his liking.

But nobody else ever romped with White Fang. He did not permit it. He stood on his dignity, and when they attempted it, his warning snarl and bristling mane were anything but playful.

He loved with single heart and refused to cheapen himself or his love.

The ghostly winter silence had given way to the great spring murmur of awakening life.

[Speaking to a group of wealthy New Yorkers] A million years ago, the cave man, without tools, with small brain, and with nothing but the strength of his body, managed to feed his wife and children, so that through him the race survived. You on the other hand, armed with all the modern means of production, multiplying the productive capacity of the cave man a million times — you are incompetents and muddlers, you are unable to secure to millions even the paltry amount of bread that would sustain their physical life. You have mismanaged the world, and it shall be taken from you.

The aim of life was meat. Life itself was meat. Life lived on life. There were the eaters and the eaten. The law was: EAT OR BE EATEN. He did not formulate the law in clear, set terms and moralize about it. He did not even think the law; he merely lived the law without thinking about it at all.

The game of life is good, though all of life may be hurt, and though all lives lose the game in the end.

Kill or be killed, eat or be eaten, was the law; and this mandate, down out of the depths of Time.
