Kinds of Propositions
Certain kinds of propositions should never be chosen for argumentation. Many are incapable of proof, so any speech upon them would result in the mere repetition of personal opinions. Such are: The pen is mightier than the sword; Business men should not read poetry; Every person should play golf; Ancient authors were greater than modern authors. Others are of no interest to contemporary audiences and for that reason should not be presented. In the Middle Ages scholars discussed such matters as how many angels could stand on the point of a needle, but today no one cares about such things.
