Course Description

The aim of this course is to enhance your skills in reasoning logically and analyzing argument. To this end we will study the principles of natural deduction, both propositional and predicate logic, as well as learning techniques for analyzing and evaluating natural arguments. Although symbolic logic is mathematical in its appearance and aesthetic appeal, and indeed forms part of the foundation of modern mathematics and computer science, it is more like an artificial language to learn, and no special aptitude for math is necessary for this course.

The main thrust of the course will be to enhance your awareness of the natural arguments you encounter every day in books, convers­ations, and the media, and to provide you with the means for evaluating many of them. This will involve learning to recognize the logical forms of arguments and how to express them symbolically, and then applying the various techniques and proofs of propositional and predicate logic to determine their validity. It will also involve learning certain less formal methods for analyzing natural arguments, including the kind of sustained theoretical arguments you meet in your academic studies. These methods will complement the methods of symbolic logic, motivating their construction and use.

Please Note the Following Policies and Statements:

Academic Dishonesty

You are expected to exhibit honesty and use ethical behaviour in all aspects of the learning process. Academic credentials you earn are rooted in principles of honesty and academic integrity.

Academic dishonesty is to knowingly act or fail to act in a way that results or could result in unearned academic credit or advantage. This behaviour can result in serious consequences, e.g. the grade of zero on an assignment, loss of credit with a notation on the transcript (notation reads: "Grade of F assigned for academic dishonesty"), and/or suspension or expulsion from the university.

It is your responsibility to understand what constitutes academic dishonesty. For information on the various types of academic dishonesty please refer to the Academic Integrity Policy, located at

The following illustrates only three forms of academic dishonesty:

  1. Plagiarism, e.g. the submission of work that is not one’s own or for which other credit has been obtained.
  2. Improper collaboration in group work.
  3. Copying or using unauthorized aids in tests and examinations.

Email correspondence policy

It is the policy of the Faculty of Humanities that all email communication sent from students to instructors (including TAs), and from students to staff, must originate from each student’s own McMaster University email account. This policy protects confidentiality and confirms the identity of the student.  Instructors will delete emails that do not originate from a McMaster email account.

Please note these regulations have changed beginning Fall 2015. You can find information at If you have any questions about the MSAF, please contact your Associate Dean's office.

Academic Accommodation of Students with Disabilities

Students who require academic accommodation must contact Student Accessibility Services (SAS) to make arrangements with a Program Coordinator.
