Worst of all, poetry corrupts the soul, strengthening the appetitive part and weakening the rational. It encourages us to indulge in emotions like pity, amusement at base jokes, sympathy with sexual lusts. Because we feel these emotions vicariously through fictional characters, and not ourselves, we believe that we are safe. However, we do not realize that once we begin to allow these sorts of emotion reign they gain power and flourish.
