There was a lot of information in chapter 6. The first thing I learned was compound claims. Epstein states that a "compound claim is one composed of other claims, but which has to be viewed as just one claim." I learned from reading the chapter is that "or" is one word that can link two claims that can make it become a compound claim. For example "I'll wash your car or I'll take it to the car wash." Chapter 6 also talks about alternatives. Epstein states that "Alternatives are the claims that are the parts of an "or" claim." Not every sentence with two or more claims is compound.
I also learned about The contradictory of a claim in chapter 6. Epstein states that "The contradictory of a claim is one that has the opposite truth-value in all possible circumstances. Sometimes a contradictory is called the negation of a claim. There are two different types of contradictory claims.
1. Contradictory of an "or" claim: A or B, not A and not B
2. Contradictory of an "and" claim: A and B, not A or not B
