There are a lot of different studies/books that refer to archetypes and the different elements of our being that can be defined by those specific, universal characters that everyone has within them to varying degrees. It's a wonderful way to help categorize the self, and to personify those elements of your being which are so dynamic and have so much control over you that they certainly may as well be their own entities.
I've done a lot of work in the study of archetypes, and I find the notion to be a very important and valid one. But the different explorations of the archetype have resulted in a library of different archetype 'sets' from which we can choose how to parcel out our being in the most clarifying way. Doing so makes the idea of the archetype just as varied as other branches in philosophy.
When is to be made of this? Are we the Fool, the Poet, the Hero? Are we more elemental, as Anger, Fear, Sorrow, Happiness, Disgust, Surprise? Are we the Trickster, the Maiden, the Child? Mother Nature, the Shaman, Night, Day? In essence we are all of these things and the myriad of other archetypes that have been determined to be the 'fundamental' archetypes. But what use does admitting we have these archetypes within us have, since if we continue to expand and agree that we can relate to every archetype handed to us, up through Spirit, we will come to the recognition that we are a little bit of everything?
People want to recognize their archetypes within themselves so they can call out recognition when one emerges. Then, analysis of the balance of their archetypes can lead to transformation and a healthier existence that transitions smoothly from archetype to archetype.
As a student of archetypal studies, I'm simply feeling a little overwhelmed by the excess of possibilities. But it's just like my previous post about sickness - with literature and the internet, we have infinite possibilities of what could be the 'true' answer. And I simply find myself overwhelmed, frequently, by the abundance of possibilities for how we can come to self-understanding and transformation. As someone who already has trouble making decisions, infinite possibilities makes it just a little more challenging.
But hey, that's the fun of it too.
