Week 9 Question 1

1). Discuss one concept in Chapter 8 that you found useful. Please explain the concept and give a personal example or personal story.

I think I found the first section of Chapter 8 the most useful, General Claims and Their Contradictories. I like how the book gave a good explanation about what "all" means and what "some" means and showed how using those words does not always work.     
All means "every single one, no exceptions." All  sometimes also means, depending on the argument, "every single one, and there is at least one." 
Some means "at least one." Some sometimes also means, depending on the argument, "at least one, but not all."

An example of using "all" would be: All of my friends are living the college experience.
This example I just used would be following the definition of "every single one, and there is at least one" because all of my friends living the college experience is about 10 people.  The contradictory of this example would be some of my friends are not living the college experience.

An example of using "some" would be: Some dogs are violent.
This example I used would be following the definition of "at least one, but not all" because I know a lot of dogs that are violent, but my dogs are not violent at all. The contradictory of this example would be No dogs are violent.
