The problem with that is that such a definition turns any “hero” into merely “first”. And once a hundred, or a thousand, or more, other people have replicated the achievement, so what? Who cares anymore? Everybody’s done it. The first person becomes a historical footnote, not a hero.

A hero is someone who do things that others cannot emulate — things that can never be reproduced. This of course requires that the hero be a person who is inherently, in terms of innate ability, someone completely out of the ordinary due to natural gifts which none other can equal or reproduce. Which is of course anathema to any sort of democratic equalitarian.

That’s part of why we don’t have heroes today. We deliberately define them out of existence, so people in general can’t recognize them when they see them.
