Caution 1 • In reconstruction, you need to separate arguments when there are two or more conclusions. • This is because the reconstruction is done to understand which sentences are the premises for which conclusion.
Caution 2 • In reconstruction, consider which statement is intended to support which other statement. • The supporting sentence is a premise, and the supported sentence is the conclusion of the same argument. • Note also that one sentence can both be a premise of one argument and be the conclusion of another argument.
Caution 3 • Don’t separate a sentence into a premise and the conclusion unless there is a supporting relationship inside. • The following sentence has a supporting relationship inside. “Because publishers are aiming at a national market, the number one criterion for any textbook is a avoidance of controversy.” • But the following sentence does not have a supporting relationship inside, so should not be divided into a premise and the conclusion. “No reason can be given why the general happiness is desirable, except when each person desires his own happiness.”
