Originating in the medieval period, polemical essays are the form for writers who wish to focus on a topic from one perspective only. They are often written to be deliberately polarizing. Refusing to shy away from volatile issues, it takes a strong writer to turn an antagonistic rant into a persuasive, polemical argument. Professor Cognard-Black shares examples of both well-written and overly strident polemical essays from authors such as Jonathan Edward and Laura Kipnis.
