According to Emerson's concept ofheroism, one of the main qualities a hero can possess is confidence, that is, confidence in one's own abilities and the certainty that he has the skills to solve a particular problem.
We can see this feature in Beowulf because he was aware of his abilities and limitations and therefore recognized that he had the ability to solve the problem that city dwellers were facing with Grendel. He knows that a strong hero can use his gift to promote goodness.
