Compound Claims and The Contradictory of a claim

After reading chapter 6, I have learned several of materials that was cover in this chapter. The parts of this chapter that I found amusing the most was about the compound claims and “or” claims and the contradictory of a claims.
Compound claims are pretty much two claims or more combined or linked together into one claim; “viewed as just one claim”. The word “or”, is a specific word that mostly used to combine two claims together to make a compound claim.
Here is an example: Bob will go to school or he will stay at home.
This is one claim that is linked together from two claims. The word “or” helps the two claim to be viewed as one claim.
The contradictory of a claim is pretty much the opposite of the claim that has the truth value of it. Meaning that it is the opposite of a claim that has the same truth value. For instance, the contradictory of an or claim for the previous example would be, Bob won’t go to school and he won’t stay at home.

  1. I think compound claims where interesting too. And I also think that they are easiest concept to grasp since it is pretty straight forward. It pretty easy to understand that or separates the two different different claims. Or is a very crucial and operative word when using a compound claim because if you used the word “and” it would totally change the claim. Bob will go to school and he will stay home. And it also makes the claim not make sense if you were talking about the same time frame, how could Bob go to school and stay home at the same time?

  2. I found compounds claims amusing as well. I see it all the time. I found the concept of compound claims to be really simple and easy to understand. In order for a claim to be a compound claim it must include a word like "or". I like the example you used because it was very easy to identify the claims. A Compound claims does not always need the word "or". Although there could be two or more claims in a sentence it does not necessarily mean its a compound claim. If the claim includes an indicator word like because it does not make it a compound claim.
