"Insults are the arguments employed by those who are in the wrong"

This quote by Jean-Jacques Rousseau suggests that when someone remains in the wrong, they may turn to insults as a way to defend their position. This indicates that those who are in the wrong might not have a legitimate argument to support their viewpoint, so they resort to insults as a way to attempt and win the argument. This quote also suggests that those who are in the right do not require to turn to insults, as they have a legitimate argument to support their perspective. This quote is a pointer that insults are not a legitimate kind of argument, which those who remain in the incorrect must not resort to them. Rather, they must focus on presenting a legitimate argument to support their perspective.
