Course summary:

            This course provides an introduction to the subject of formal reasoning.  We will study modern formal logic, usually called mathematical or symbolic logic.  This is a system for understanding the formal structure of our thinking (yes, our thought is structured!), much the way mathematics is a system for understanding the formal structure of our counting and measuring.    Think how difficult it is to divide 3974 candy bars into 297.43 groups--manipulating the bars by hand.  Work out that same problem formally with mathematical symbols, and it becomes an easy (if tedious) long division problem.  Logic is in some ways similar.  There are uses for a formal system to help us understand our reasoning and even to help us reason, in ways that would be extremely difficult if not impossible if we lacked the symbolic system to think with.

            Class format will be mostly lecture.   We will work some problems on the board.  You will have frequent reading assignments and homework.

            This course meets the Humanities distribution requirement, but you may use only one of RELP 1155 or 1166 to meet this requirement.

 

Requirements and grading:

            1. Attendance is required.  During a lecture, I might elicit some material from you.  So, you must keep up with the readings, that day's class and the ongoing course.  You need to be mentally active and prepared. Your participation in class--working problems on the board, answering questions, raising relevant issues—can raise your grade up to 1/3 of a grade.  Also, some homework problems will be graded.  I do not much mind if you work on homework with your colleagues.  Remember, though, that you will not profit from the homework if you do not at least think it through for yourself.  I will not accept late homework assignments; do not turn them in.  Those assignments to be turned in are due at the beginning of class.   TOTAL of homework: 10% of your grade

 

            2) Three pop quizzes, each 5% of your grade.  None will not take the entire period and each will test a limited amount of material.  NO makeup quizzes.  TOTAL of quizzes: 15% of your grade

 

            3) Two scheduled tests, each 25% of your grade.   Tentative dates:  Sept. 30 and Nov. 4.   Each will test a substantial amount of material.  If you miss an exam, you must contact me immediately.  If you know you have to miss it, contact me beforehand.  We will have a serious talk; I do not guarantee that you will be permitted a make-up exam.  TOTAL of tests: 50% of your grade

 

            4) A comprehensive final exam, 25% of your grade.  You cannot receive a LOWER grade for the course than you receive on the final exam, IF AND ONLY IF you have taken all tests AND at least two quizzes AND you do not have a serious attendance problem.   Exam date:  Monday,  Dec. 12, 11:30 - 2:30; bring pencils and (if you need it) scratch paper.

Here is what the grades mean:

            "A"       Superior mastery

            "B"       Good mastery

            "C"       Satisfactory achievement

            "D"       Less than satisfactory achievement

            "F"        Unsatisfactory achievement; Failure to achieve minimum competency

I will employ plus/minus grades, but A+ is not a possible final grade for the course:

A+  97-100                    B+  87-89                      C+  77-79                      D+  67-69

A    93-96                      B    83-86                      C    73-76                      D    63-66

A-   90-92                      B-   80-82                      C-   70-72                      D-   60-62

 As indicated, grades measure achievement.

 

Text:

            Howard Pospesel's Introduction to Logic: PROPOSITIONAL LOGIC (revised 3rd edition).  It comes with a very helpful CD at the end containing a Logic program that allows you to check your own homework.  You should use this easy program; see appendix 5 in the book for help. 

 

Reading, taking notes, and homework:

            Read the assigned passages carefully. Some of the material is easy and accessible on your first attempt.  Other assignments are taxing and will require multiple readings.  I advise you to take notes on what you read, since I will lecture on only those parts I consider essential for us to cover in class.  You are responsible for everything in the assigned readings, whether or not it is covered in class.  Lectures can cover material not in the readings; this is another reason to attend.

            Most students take very sketchy notes.  Perhaps they think that they cannot take notes and listen at once; perhaps they do not appreciate the value of taking notes.  Learn to write while you listen; it not only can be done, it usually enhances your grasp of what is being said.  Take as many notes as you can, without losing too much of what is being said.  Your notes are an invaluable resource both for understanding the course and for the final exam.

            Do all assigned homework, whether or not you are to turn it in.  Work out the logic problems you are presented with in class or in the book.  Beginning logic students typically suffer from what we might call the "eye-hand disease".  Those suffering from this ailment see a problem worked out for them in class or the book and sincerely believe that they understand how to do that kind of problem simply by seeing it done.  Then test time arrives (or graded homework is returned), and it is clear that they didn't really understand--though they thought they had.  WARNING: you often will not truly understand a logic exercise until you do it yourself by hand.  Practice!  If you get behind, even with your best efforts, see me for some extra help.

 

Absences and violations:

            To help with attendance--and to learn names--I will institute a seating chart on the 2nnd day of class.  Pick your permanent seat;  change it only by notifying me.   If late, you risk being counted absent.  Tardiness should be rare; if you are often late, I will deliberately count you as absent.

            No absences are excused.  After 3 penalty-free absences—no explanation needed--others lower your final grade:  4-5 by 1/3 grade, 6-8 by 2/3 grade, 9-10 by 1 grade.  Missing class just before or after vacation counts double.  Over 10 absences for other than an emergency is automatic grounds for an "F" (or an "I" in some cases), regardless of your grades.  Sleeping or other forms of mental non-attendance count as an absence.  When absent, you are responsible for missed assignments and classroom material.  Get notes from a classmate.  If you still have questions, contact me.  Cheating, as well as falsifying an emergency to skip class or an assignment, violates the Honor Code.
