interesting facts

After looking through chapter 6 and 7 for something that is interesting that I have not yet mention this week. Than I came across the reasoning from hypotheses in chapter 6. The main key that help to reason with hypotheses is start with hypothesis A. After giving the hypothesis A, follow by making a good argument for B. This idea is kind of similar to conditional claim: If A, then B.

Example argument: Lin: I think I'll walk to John's house today.
Casey: If you do make sure to take an umbrella.
Lin: Why do I need an umbrella? It's not raining outside.
Casey: The weather forecast said that it's going to rain later in the day and the clouds are seem to hang really low in the sky. It'll rain soon and you will need an umbrella on the way back.
In the example, Casey does not tell that Lin need an umbrella. Rather, Casey assume that Lin will stay at John's house until later in the day. By that time it'll rain and Lin will need an umbrella to walk back home.
