I think that the major defining factor of a hero is that he/she can do something exceptional, something that is difficult to attain by an ordinary person. Therefore, the qualities of a hero will change based on what qualities a person values, and what qualities they wish to emulate. This explains why, to one person, Achilles was a hero and to another, Justin Bieber is. For the ancient Greeks, the highest honor was to be a war hero, to die valiantly (and often violently) in battle. Achilles was best emulation of this ideology, and so he remained a heroic figure for centuries.Â
I think it's also worth noting that the ancient Greeks were all encouraged, by their philosophers and by their government, to value the same things. They were encouraged to act according to their gender roles, social class and overall to act in accordance with societal values. This also explains why the value placed on Achilles has endured for so long- because he was the hero not just of one, but of many.
I'm not trying to equate Justin Bieber with Achilles, but each of them is a heroic figure for someone, based on what they represent. For Achilles, it’s war valor and for Justin, it’s fame and success.  Regardless of what you're opinion on Justin Bieber, his talent or his music his, he represents the ability to become famous and successful from humble beginnings- a desire held by many.Â
I would definitely agree with you in saying that the word “hero” is probably overused today. I don’t think that someone is your “hero” for letting you borrow a pen in class or for giving you a ride home. It’s a nice sentiment, but probably not an accurate one. We’re in agreement there.Â
What is disagree with is that I don't necessarily think that the term hero being used differently than the standards that Homer wrote about is necessarily a bad thing. Changing heroes, in my opinion, is a good thing. For Homer's audience. Achilles was the embodiment of THE type of hero that every man should strive to be. Today, I feel like every person is encouraged more to think for themselves, value different things and as a result, have different heroes. Sure, this means that some people’s heroes are going to be Paris Hilton and Lindsay Lohan. But it also means that some heroes are going to be Stephen Hawking or Anna Pavlova, and Mahatma Ghandi or Amelia Earhart can be heroes too, not just Achilles and Hector. It means that both personally and as a society, we can recognize that compassion, generosity, drive and peace can be traits just as heroic as bravery and sacrifice.Â
There’s definitely “cause for concern” about heroes in today’s pop culture. I’m just as disgusted as the next person about the fame and attention who surround celebrities (to use the trite example, like Kim Kardashian) who are almost worshipped, despite having done very little to merit fame and who, even worse, do very little with their fame to give back to society. In that sense, I am just concerned about the “lack of focus” in pop culture heroes. But what I remain hopeful about is that even though the diversification in the traits we find heroic might distort our priorities a little, we’re greater advantaged by the influx of new heroic traits, that encourage us to be different from each other but still successful in our own way.Â
The definition of hero from Homer to today has certainly changed, in manners good and bad. We understand Achilles as a historical hero, but he might not be what we desire to emulate today. I like that our heroes can reflect who we are and who we want to be, not who society thinks we ought to be.
