"We know what happens to people who stay in the middle of the road. They get run over"

This quote by Ambrose Bierce suggests that remaining neutral or indecisive in one's beliefs and actions can be harmful. Bierce might be highlighting the significance of deciding and being firm in one's convictions. People who stay in the middle of the roadway are unprotected and susceptible to being run over or overrun by those with stronger opinions and convictions. Bierce might be recommending that it is better to take a side, even if it implies taking a threat or standing apart from the crowd. In essence, Bierce is promoting for nerve, conviction, and action.
