Another aspect of chapter eight I found interesting the general claims and their contradictions. A general claim is when something is asserted in a general way is stated about a collection. For example all sorority girls are blonde, Jen is a sorority girl so Jen must be blonde. This may seem valid but it is not. Girls in sororities have different hair color and are not all blonde. All means every single one with no exceptions and I think people need to use this word more carefully when stating a claim. When using the word “some” it means a least one but not all and is a really vague word to use in an argument because it is not a specific number. The word “no” means not a single one with no exceptions and needs to be sure when inserted into an argument that exceptions can not be made.

Chapter 7
One aspect of chapter 7 that I learned a lot from is the section on raising objectives. This got my attention because after giving an argument and agreeing with the statement it is irrational to say an argument is good and then deny its conclusion. This is a simple way to show an argument is bad. By showing an argument is bad we can either question a premise, show that an unstated premise is questionable or gives an example of why the argument is weak. This method also makes you have a stronger argument because after you write your argument and think of someone objecting to it, you can see where you can make improvements. The other aspect of chapter 7 that goes along with raising objectives is refuting arguments directly. You can refute an argument directly by showing one of the premises can be objected to, giving examples of how the argument is invalid or showing that the conclusion is false.

Chapter 6
One thing I learned in Chapter 6 that I found really interesting was how a false dilemma in an “or” situation was explained. This happens a lot in everyday conversation because a false dilemma is a bad use of excluding possibilities where the “or” claim is false or implausible. This is because in a statement such as “You can either go to collage or move out of the house.” This is an example of a false dilemma because there are many other options that are not explained in the argument, which makes for a bad and weak argument. The second idea that I found interesting in chapter 6 is conditional claims. This is a claim that can be written as an “if/then” claim and still have the same truth-value. It is still possible to have an “if/then” claim without having the actual words in it. This is when a statement is a conditional because you do not separate the if then statements and a premise and a answer but just as one statement.
