The aim of this course is to familiarize students with fundamental techniques of correct reasoning. Special attention is given to the methods of logic in particular, and to their role in the discovery of truth not only within science and philosophy but within all forms of rational enquiry. Open to all students. Quantitative.


This course introduces students to the logic of good reasoning. We focus on the main elements of deductive logic, which is primarily concerned with correctly deducing a conclusion from given premises, or what is often called “valid inference” or “logical consequence”. We begin with propositional logic, where we focus on the logical properties of whole sentences and arguments built with them. We then proceed to develop a proof system—a system of deduction—for this, i.e., a way of deriving logical consequences from given sentences as a starting point. We end the course by looking at elements of first-order logic, which contains quantifiers and variables, and which gives a correspondingly more complex means of expression and system of deduction.

An introductory study of logic provides excellent preparation for intellectual work in many other disciplines. Students from all faculties will benefit from learning various methods of sound reasoning—methods that prize precision, clarity, rigor, practice, and patience. Students in this course should expect to develop an enhanced ability to engage in disciplined argument and to write in an organized and focused way.

This course assumes no prior knowledge of logic, and is intended for all students, whether or not they are planning further study in philosophy.


PHIL 110 may be applied towards the Quantitative Requirement. It is also a required course for the Philosophy Major.

By the end of the course, students will be able to:

  1. Assess the quality of an argument using formal methods
  2. Appreciate the general principles of good reasoning  
  3. Determine the validity of an argument in terms of its logical form
  4. Symbolize English arguments using logical notation introduced in the course
  5. Translate sentences expressed in logical notation into English
  6. Demonstrate an understanding of basic logical concepts (truth-functions, validity, soundness, deduction and quantification)

  • Students can use a P or CR to satisfy any requirement for a major, joint major, honours, or minor in Philosophy (with the exception of Honours tutorials).
  • Students can use a P or CR to satisfy any prerequisite requirement for any PHIL course.
  • Students can use a P (but not a CR) to satisfy any requirement for the Ethics Certificate, or the Philosophy and Methodology of Science Certificate.
  • Philosophy Majors and Honours students can use a P (but not a CR) to satisfy any WQB requirement.

Registrar Notes:


SFU’s Academic Integrity web site is filled with information on what is meant by academic dishonesty, where you can find resources to help with your studies and the consequences of cheating.  Check out the site for more information and videos that help explain the issues in plain English.

Each student is responsible for his or her conduct as it affects the University community.  Academic dishonesty, in whatever form, is ultimately destructive of the values of the University. Furthermore, it is unfair and discouraging to the majority of students who pursue their studies honestly. Scholarly integrity is required of all members of the University.


Teaching at SFU in summer 2022 will involve primarily in-person instruction.  Some courses may be offered through alternative methods (remote, online, blended), and if so, this will be clearly identified in the schedule of classes. 

Enrolling in a course acknowledges that you are able to attend in whatever format is required.  You should not enroll in a course that is in-person if you are not able to return to campus, and should be aware that remote, online, or blended courses study may entail different modes of learning, interaction with your instructor, and ways of getting feedback on your work than may be the case for in-person classes.

Students with hidden or visible disabilities who may need class or exam accommodations, including in the context of remote learning, are advised to register with the SFU Centre for Accessible Learning ( or 778-782-3112) as early as possible in order to prepare for the summer 2022 term.
