The Call of the Wild
How we cite our quotes:
In the main they were the wild wolf husky breed. Every night, regularly, at nine, at twelve, at three, they lifted a nocturnal song, a weird and eerie chant, in which it was Buck's delight to join. (3.27)
Buck finds camaraderie with wild wolves because he recognizes his own primitivity in them.
It was an old song, old as the breed itself--one of the first songs of the younger world in a day when songs were sad. It was invested with the woe of unnumbered generations, this plaint by which Buck was so strangely stirred. When he moaned and sobbed, it was with the pain of living that was of old the pain of his wild fathers, and the fear and mystery of the cold and dark that was to them fear and mystery. 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. (3.28)
Buck finds camaraderie in the past generations of dogs like himself because they have all suffered similar hardships in the wild.
All that stirring of old instincts which at stated periods drives men out from the sounding cities to forest and plain to kill things by chemically propelled leaden pellets, the blood lust, the joy to kill--all this was Buck's, only it was infinitely more intimate. (3.33)
Buck finds a connection to his past when he experiences killing.
