We can learn a lot from wolves. Pohnpei did a good job explaining the benefits of wolf responsibility and how humans can learn a lot from their wolf society in Rudyard Kipling's The Jungle Book as a whole and "The Law of the Jungle" specifically. Let's take a look at some specifics of the poem that show the rights and responsibilities of wolves (and people).
Interestingly enough, Kipling begins with the responsibilities and ENDS with the rights! Both are almost always contained in the first line of a stanza. Let's begin with what Kipling does: responsibilities. There are many, but here are a few important ones
Ye may kill for yourselves, and your mates, / ... But kill not for pleasure
The Kill of the Pack is the meat of the Pack
The Kill of the Wolf is the meat of the Wolf.
If humans need to learn one thing it is not to kill "for pleasure." Wolves, according to Kipling, have the same responsibility. You will see quickly that rights and responsibilities begin to blend together. While the pack has a responsibility to help kill, they all have the right to eat it. However, if one wolf makes a kill, he can eat it on his own.
Now, Kipling believes, it is finally time to discuss the rights of the wolf.
Pack-Right is the right of the meanest
Cub-Right is the right of the Yearling
Lair-Right is the right of the Mother.
Cave-Right is the right of the Father --
Here we learn that the meanest wolves are left the best meat. Further, the young are able to eat as much as they want when they want in "full-gorge." No wolf can deny a young cub this right. We also learn that mother wolves have major rights, too, called the "lair-right." This, again, is about food for the young, actually. A mother is allowed to take any "haunch" for her young so that they can eat before they can claim it for themselves as cubs. Finally, the wolf fathers have rights, too. Fathers are welcome to actually ignore the call of the pack and hunt for their own family.
Thus, you can see that the message of the poem is that wolves have responsibilities before rights. Humans should have the same.
