ABSTRACT
Everyone knows that coercion is necessary for ordinary men, yet many philosophers have believed that perfectly good and wise men could do without it, that perfect men left alone would inhabit utopias. It is a pleasant thought, though I think not a true one. I believe that even perfect men could need coercion. In substantiation, however, I demonstrate here only a weaker thesis by considering hyperrational act-utilitarians and, without any attempt to defend or to assess their claim to perfection, by showing that they too could need coercion.
