This course is not
going to teach you logic. You already
use logic all the time, as you will discover on Class Day 1. It will, however, help you to sharpen your
reasoning skills considerably, so much so that you will no doubt feel “smarter”
when it has been completed. That will
be accomplished through our concentrating on the principles of correct
reasoning, both formal and informal. In
this class you will develop such specialized skills a distinguishing
argumentative from non-argumentative passages in ordinary language, analyzing the
form of an argument, and recognizing the moves known to the tradition as
‘fallacies’, or ‘mistakes’ in reasoning, both formal and informal. Further, you will become familiar with (and,
I hope, proficient at) deductive logic, of syllogistic, sentential, and
propositional types. Ultimately, you
will learn to employ several techniques for determining the validity or
invalidity of arguments in both ordinary language and in symbolic form, and to
critically evaluate arguments you run across every day.
I WANT YOU TO KNOW RIGHT UP FRONT THAT THE ONLY WAY TO BECOME PROFICIENT IN LOGIC IS THROUGH PRACTICE!!! --Like learning to ride a bicycle, simply reading the book or watching the video doesn’t get you there.
PROCEDURES: The
reading assigned for a given day should be done prior to class, to facilitate
our discussions. Homework problems will
be assigned each meeting. Grades,
however, will not be based upon homework.
In the name of anti-authoritarianism and personal autonomy, I will not
coerce anybody into doing homework. I
will do some exercises from each assignment at the beginning of the next class
period, but will be looking to help students with the ones that proved
difficult, which of course will not be identified unless people try them.
If it is not clear
enough from the above, let me say this now—people who do not attend class
regularly generally do not do well in logic courses. So, while I do not make it my business to penalize absences, they
do carry in themselves a potential penalty.
Still, it is your responsibility to determine whether missing class is a
problem for you.
Grades will be based
on the 4 (non-cumulative) tests and two writing assignments, according to the
following breakdown:
Test 1 20%
Test 2 20%
Test 3 20%
Test 4 20%
Fallacies Paper 10%
SEARCH Paper 10%
Required Texts:
The Power of
Logic, Stephen Layman (PL)
Study Guide to
the Power of Logic, Stephen
Layman
How to Think
About Weird Things, 3rd
ed., (but 2nd will work)*
Theodore Schick and Lewis
Vaughn (WT)
*I have listed page
numbers in the course schedule for both editions, marked with ‘ii’ for the 2nd
edition and ‘iii’ for the 3rd.
The study guide is a recommended
addition to the texts you will be using for this course, but it is not
required. It summarizes chapters, gives
a brief overview of the key concepts for each chapter, and provides supplementary
exercises (with answers) for each chapter.
It is not an answer key to the exercises in the regular text, but it
does give the answers to the “selected” questions from the text, which are also
found at the back of the textbook. If
you find that you are having difficulty with reading The Power of Logic,
perhaps the study guide would be of assistance, given that sometimes a briefer
presentation is easier to understand.
