Compound Claims

There are many claims that one may use in an argument. The two concepts that caught my attention in chapter 6 was compound claims and conditionals. Within compound claims there are sub points of it such as: alternative claims, contradictory of a claim, and false dilemmas. According to the Epstein text a compound claim is "one composed of other claims, but which has to be viewed as just one claim." Words can link two or more claims together which can form a compound claim. There are also sentences with two or more claims that are not considered a compound claim. An alternative is a claim that is part of an "or" claim. A contradictory of a claim is one that has the opposite truth-value in all possible circumstances. Another word for contradictory is negation of a claim. A false dilemma is a type of logical fallacy. A false dilemma is a situation that involves two alternatives that are considered, when in fact there are three other options. It is considered a bad use of excluding possibilities where the "or" claim is false or implausible. Claims that are considered conditionals when it can be rewritten as an "if...then..."claims that must have the same truth-value.
