Section 7.8 The Dilemma of Copi's Introduction to Logic says:
The dilemma is a common form of argument in ordinary language. It is, in essence, an argumentative device in which syllogisms on the same topic are combined, sometimes with devastating effect.
and
A dilemma need not always have an unpleasant conclusion. An example of one with a happy conclusion is provided by the following simple dilemma:
If the blest in heaven have no desires, they will be perfectly content; so they will be also if their desires are fully gratified; but either they will have no desires, or have them fully gratified; therefore they will be perfectly content.
So is dilemma a suitable word for that form or arguments?
Does logic have a more proper word to mean something similar to dilemma but neutral?
