To dispel prejudice, Aristotle suggests an appeal to character without specific comment on the prejudice. Alternatively, the situation may be confronted openly (Aristotle III.15, B. 1416a). The wrong may be denied outright or mitigated with other data. It is also often possible to implicate your accuser in similar wrongs. Aristotle goes on to suggest that denouncing the criticisms lodged may also be effective (Aristotle III.15, B. 1416b).
