For the Midterm …I will provide you with a categorical proposition, like…

All cars that are not Mazdas are cars with good jingles

I’ll ask you for its quality qualifier quantity quantifier copula distribution letter name terms

1

How many quantifiers are there? List them…

2

How many qualifiers are there? List them…

3

Memorize distribution!

All SD are PNo SD are PD

Some S are PSome S are not PD

4

Standard Form…

Which is in standard form, and why?

Some eyebrow tweezings are less than pain free procedures

10No S are P. (Aristotelian standpoint)

After filling in the diagram …a.Area 2 is shaded, and there is a circled X in area 1.b.Areas 1 and 3 are shaded.c.Area 1 is shaded, and there is a circled X in area 2.d.There is an X in area 2.e.Area 1 is shaded, and there are no other marks.

11All S are P. (Boolean standpoint)

12Shade area 2 and place an X in area 1.

Which of the following would be valid inferences:a.shaded area 2.b.an X in area 3.c.an X in area 1.d.shaded 1.e.no X’s or shadings.

13Shade area 1 and place an X in area 2.

Which of the following would be valid inferences:a.shaded area 2.b.an X in area 3.c.shaded area 1, and X in area 2.d.shaded 1.e.no X’s or shadings.

20

Know the 3 theories of truth, and their general problems…

21

“There were only 2 people in the room at the time of the murder … we can, therefore, exclude the fact that there was a large crowd in the room at that time.”

Is this a correct, or incorrect use of the notion of a fact?

22

Identify the species, genus, and difference at work in these Genus-Difference definitions…

An elephant is an animal with a trunk

A laptop is a computer made to sit in your lap

22 (continued)

Elephant = animal trunk

Laptop = computer for your lap

Species Genus Difference

Species Genus Difference

Read section 4.7 on your own.

You will have 4 sentences to translate, but none of them will involve converting a single statement into 2 categorical propositions.

Good luck!
