It feels sort of like my conscience is Badger and my life is Toad. Toad is reckless and want to have fun while Badger is more responsible and stops hubris in it's tracks. I might want to go places but there comes a point when safety, or social responsibility according to Badger, becomes the greater issue. Before detailing my analysis of the epiphany of Pan in chapter 7, there's something else I want to mention first.
It is the strangest most ironic act of personification that a non human animal would use the name of another animal as a derogatory slur. This is doubly strange because all of the animals eat meat from that very animal while using other words ("bacon" and "sausage") to describe the meat. Why don't they just say "I'm eating pig?" They don't because that's not how humans do it. We don't often like to put a face on our food. It's easier to put a face on ourselves and ignore shared commonalities with other species. "I see it all now! What a pig I have been! A pig - that's me! Just a pig - plain pig!"(p83)Moving on to chapter 7...
I think purpose is a necessary ingredient for the epiphanic experience had by Rat and Mole in chapter 7. "Rat," said the Mole, "I simply can't go and turn in, and go to sleep, and do nothing, even though there doesn't seem to be anything to be done."(p119) Purpose is not simply a driving factor to get the characters into a certain physical location where they then have their epiphany (though this is exactly the case with Pan and the music he used to call them to Portly). Rat and Mole never would have had their experience if they hadn't had the goal, the purpose, of finding Portly. If you reduce every philosophical question further and further down to the most basic question of all, you come to "why are we here?" There is an answer to this though wordy academic types tend to try to poke at it. The answer to "why are we here" is simply this: we are here to bring forth the next generation and do the best we can for it. That is the purpose of life, to perpetuate itself. Rat and Mole are seeking one of the next generation, the most important thing they could possibly do, and I think the whole Pan-epiphany thing is really just an accentuated, literary highlighter for this. The most important sentence in the entire chapter comes after the description of Otters vigil by the water. "Looking up the river, they could see Otter start up, tense and rigid, from out of the shallows where he crouched in dumb patience, and could hear his amazed and joyous bark as he bounded up through the osiers on to the path." Perhaps the experience granted to Rat and Mole was a reward, a boon of sorts, for their efforts as good samaritans.
I also think it's interesting that the book ends on an epic feast. Food is the great binding ingredient of society, whether Badger is ordering "everything of the best" or I am being vocal about vegan things. Reread the end closely. Kenneth Grahame got it right. It's all about food.
