PHIL
1500 - Critical Thinking
Unit 3: Analogical Arguments
Dr. Donald Nute
Exercises
For each of the following arguments,
identify the target subject, the target attribute, the comparison set, and the
comparison attribute(s). Then evaluate each argument using the six criteria discussed
above. Think of ways that the premise or the conclusion of these arguments might
be altered to strengthen the arguments.
- Jupiter, Saturn, and
Uranus are all gas giants. All of them have rings. Neptune is also a gas giant.
It probably has a ring, too.
- When I took chemistry,
I had pneumonia. I missed a lot of classes and made a poor grade. When I took
physics, I broke both legs in a car accident. I missed a lot of classes and
made a poor grade. Now I am taking astronomy and I have a cold. I probably
should drop the class.
- Mother Theresa and Albert
Sweitzer both smiled a lot, and both were very kind people. Bill Clinton smiles
a lot. He is probably a kind person.
- The Toyota Corolla,
the Honda Civic, and the Nissan Sentra are all small cars with four cylinder
engines, and they are all very reliable. The Daewoo Lanos is a small car with
a four cylinder engine. It is probably very reliable.
- Benjamin Netanyahu once
said, "Saying you are not antisemitic, you are only anti-Zionist, is like
saying you are not against Americans, you just don't think America should
exist."
- Saying the terrorists
who attacked the World Trade Center and the Pentagon are Muslims and your
neighbor is a Muslim, so your neighbor is probably a terrorist, is like saying
the people who blew up the federal building in Oklahoma city were Americans
and you are an American, so you probably blow up buildings.
