Throughout this passage, Wiglaf is presented as a model of loyalty. When all other warriors act like cowards, retreating to safety, Wiglaf decides to risk his life and stand by his old king in this last battle. He still doesn't act as Beowulf's equal, but he nevertheless offers him support, as his sworn warrior. Beowulf is indeed encouraged by this act and manages to kill the dragon while receiving a mortal wound himself.

Learned people are better than unlearned people when it comes to giving general advice, according to Bacon.
He believes that the more educated a person is, the more likely they are to give good advice about general things in life. Knowledge and the level of learning greatly impacts the ability to provide others with valuable advice. The other options can be performed equally well by both learned and unlearned people.
