What This Course Is About

This class introduces students to formal techniques for evaluating arguments. These are the principles that underlie all sound reasoning as well as the design of all contemporary computer systems.

We cover a natural deduction system of sentential logic, truth-tables, a natural deduction system of first-order predicate logic, and the basic ideas of model theory. Exams are designed to test skill with the formal systems, particularly translation from English to formulas, proof techniques, and methods for showing invalidity. The skills that you will learn with these specific methods are not ends in themselves, but tools to help you understand what it really means to reason logically.

Course Objectives

After taking this course, you should:

In addition to these specific objectives, this course should help you understand and analyze complex arguments and reasoning. That ability is useful preparation for many careers and for standardized tests such as the GRE, the LSAT, and the GMAT.

There are no prerequisites for the course. It satisfies a core-curriculum quantitative reasoning requirement for many students.

Basis for Grades

ExamDatePortion of grade
Exam 1 (sentential logic)Oct. 630%
Exam 2 (predicate logic)Nov. 2430%
Weekly quizzesAnnounced in lab sessions20%

Weekly quizzes will be announced in discussion sections. There may be a quiz in any given week (in other words, these are surprise quizzes for which you should always be prepared).

Grading scale: A = 90% or better, B = 80% or better, C = 70% or better, D = 60% or better, F = less than 60%. The maximum total of all exams and quizzes is 110%; what this means is that you can earn up to 10% extra credit.

Grades online are available at this site. You will need to register a password first.

Attendance

Class attendance is not part of the grading basis for this course. That means both that you do not lose points for not attending class and that you do not get points just for attending class. If you can learn the material without coming to class, more power to you. However, you should be aware that:

Makeup exams and quizzes will be provided for students who have missed them because of University-approved absences only. See Student Rules, Section 7 for the University's policy on attendance and for the definition of "University-approved absence".

How to Do Well in This Course

Learning logic is like learning a foreign language or learning mathematics: it involves learning how to do something, not just learning facts, and what you learn is cumulative. Here are three keys to success in this course:

  1. Keep up. Do the readings and exercises as they are assigned in the schedule. The material in this course is not friendly to last-minute cramming. Don't let yourself get behind.
  2. Practice. Lots. To succeed in this course, you have to learn how to do things, not merely learn some facts. That takes practice, repetition, doing the same thing over and over, repetition, practice, doing lots of exercises, practice, and doing things over and over. You have to practice. Repetition is essential. It gets easier if you do it many times. Do lots of exercises. One valuable source of help here is our online support for this course, which never sleeps, is always ready to help you practice, and will give you instant feedback on how you're doing.
  3. If you need help, ask for it. Immediately. There are several sources of help built into this course. Your discussion sections are intended to be times when you can ask questions about what you don't understand. Your section leader has office hours available for you. We have online help. However, these are only going to be useful to you if you ask.

Lecture and Exam Schedule

If circumstances require postponing the date of any exam, this will be announced both in class and on this web site at least 7 days in advance.

Academic Integrity Statement

The Aggie Honor Code:

"An Aggie does not lie, cheat, or steal or tolerate those who do."

Effective September 1, 2004, Texas A&M University has an Honor Code that defines campus policy on academic integrity and academic misconduct. The Aggie Honor System is charged with the enforcement of this Code. Students should be aware that the Aggie Honor System has the power to impose punishments for academic misconduct. For information on the Aggie Honor System, see http://www.tamu.edu/aggiehonor; information of particular concern to students, including definitions of types of academic misconduct, may be found at http://www.tamu.edu/aggiehonor/student.html.

It will be my policy in this course to include the following statement on all examinations and request students to sign it:

 "On my honor, as an Aggie, I have neither given nor received unauthorized aid on this academic work."
