Lecture 4A: Diagraming Arguments

Homework Review 3B
1. Short cut method

2. Examples (+assumptions):
(1)  People have differing opinions about what's right and wrong therefore, moral truth is subjective. (Mackie)

(2)  There are universal moral principles because all cultures agree that, in general, children are valuable and should be protected, murder is wrong, and you should not break promises.  (Rachels)

(3)  The soul is said to be immaterial and the body material.  Something that has no spacial or material existence cannot causally affect something that does have a spacial and material existence--and vice versa.  It follows that we either don't have a soul or that our soul has no causal power over our bodies' actions.  (Churchland)

(4)  Critical thinking is the most important course in the wooooooooooooooooorld:  You learn how think more clearly, you learn how to separate good arguments from bad arguments, you learn how to avoid common cognitive errors which could cause you to make poor decisions, and you get to learn how to sound smrt.

3.  The blog won't let me upload diagrams so for the lesson notes, please refer to the hand out.  I'll also email a copy to all of you.
