English teacher John Keating inspires his students to look at poetry with a different perspective of authentic knowledge and feeling.

IMHO: ?the "Hero's Journey" is a paradigm best suited for stories about men in the 1st half of life. ?Like the students in DPS. ?It doesn't address the psychological and existential agendas of men in later life. ?Nor to women at any age.

(I am curious to see how -- if -- they can work out Rey's ?character arc in the reboot of the Star Wars franchise so that it more substantial than a ?guy's "Hero's Journey" in drag. ?Given the fact that all the writers in "The Force Awakens" were guys, ?I'm not optimistic.)

The books have far more detail but as an online resource this provides a few good points.

Protagonist, as defined in greek, means the primary fighter. The hero, according to ?Campbell, will face an ordeal and return with the elixir. In other words, the hero will undergo change and learn a lesson over the course of the journey.

As there is no definitive description for either hero or protagonist, that sets them as conventions by which the industry operates, it seems that the particulars of the definitions are up to the writer at hand. Please read for yourself (as you have done in the past) and I'm sure you'll come up with?definitions that are not far from the ones I posted.

This discussion has been fascinating to follow.

Having read THE HERO'S JOURNEY (a couple times...long ago), I'm familiar enough to follow along with and comprehend your terminology, while continuing to learn from it.

I'm not sold on Nir Shelter's defined distinction between the following:
Protagonist - a character that uses action, more than others, to progress the A plot.
Hero - the character that experiences the most amount of change over the course of the story, or the one with the [greatest?] lesson.

I see that there should be a distinction, but that perhaps there should be another description altogether for "Hero," while "Protagonist" assimilates the given definition of the other.
What that new definition for "Hero" should, then, be might already be defined by Vogler. If I knew where my copy was, I'd gladly research it myself.
