TEXTBOOK: Introduction to Logic, 13th Edition, Irving M. Copi & Carl Cohen, Pearson, Prentice Hall, Upper Saddle River, New Jersey, 2009. (This text is required. We will use it daily in class.) You may use the 12th edition of the text. A separate syllabus for the 12th edition will be available online.

COURSE DESCRIPTION: “The study of arguments, including basic principles of traditional logic together with an introduction to modern sentential logic. Topics include recognizing arguments, premises, conclusions, induction and deduction, fallacies, categorical syllogisms, and sentential inference forms” (USD Course Catalog). This course satisfies the logic requirement.

COURSE OBJECTIVES: During this course, students will be asked to do some or all of the following:
1.    Distinguish arguments from non-arguments
2.    Distinguish deductive arguments from inductive arguments
3.    Identify the premises and conclusion of arguments
4.    Identify types of informal fallacies
5.    Test arguments for validity using Venn diagrams and/or truth tables and indirect truth tables
6.    Distinguish necessary and sufficient conditions
7.    Translate sentences into propositional logic
8.    Apply the techniques of natural deduction to proving arguments (this may include reduction and conditional proofs)

COURSE CALENDAR (topics and important dates included):
(Homework will be due daily and assignments will be announced in class. Do not be concerned if we fall ahead or behind on this schedule. The most important goal is that everyone understand the concepts and problems. This schedule is subject to change. All changes will be announced in class and posted on the course website)

Student Responsibility to Drop/Withdraw: It is the student’s responsibility to officially add, drop, or withdraw from the course stated in the class schedule. Failure to do so can result in a failing grade.

Class Attendance: A student may be disenrolled from the course after two absences; however, a student will be disenrolled from the course after three absences without exception. (This count will begin at the first session of Week 3.) ATTENDANCE IS VERY IMPORTANT FOR THIS PARTICULAR COURSE.

Tardiness/Early Departure: If a student arrives unreasonably late or leaves early without notifying the instructor before the event, then that student will be considered absent for that class session.

Professionalism: It is assumed that students will conduct themselves in a professional manner with a positive attitude. An open mind is one of the most important tools required for success in academia. If a student is negative and feels as is there is nothing of value to be gained by the college experience or this course, he or she will not do well in this course.

Academic Integrity and Conduct: Plagiarism, cheating and poor student conduct will not be tolerated. Students are expected to familiarize themselves with the USD Integrity Policy. This can be found at

Accommodations for Students with Disabilities: Students with disabilities who may need accommodations in this class are encouraged to notify the instructor and Disability Services. Information can be found at
