Overview

Philosophy 254: Symbolic Logic is a junior-level, three-credit course that provides an introduction to formal methods of evaluating reasoning. It will teach you how to translate English arguments into symbolic notation, and then how to evaluate these symbolic arguments to determine if they are logically valid.

Outline

The course is divided into sixteen modules:

  • Module 1: Introduction to Logic
  • Module 2: The Structure of Sentential Logic
  • Module 3: Computing Truth Values
  • Module 4: Symbolizing English Sentences
  • Module 5: Truth Tables for Testing Validity
  • Module 6: Further Applications of the Truth Table Method
  • Module 7: The Proof Method: Eight Basic Inference Rules
  • Module 8: Replacement Rules
  • Module 9: Conditional Proof and Indirect Proof
  • Module 10: Singular Sentences
  • Module 11: Quantifiers
  • Module 12: Categorical Propositions
  • Module 13: Complex Subjects and Predicates
  • Module 14: Quantifier Form and Truth-Functional Compounds of Quantifier Statements
  • Module 15: Proofs in Predicate Logic
  • Module 16: Invalidity in Quantifier Logic

Learning Outcomes

Philosophy 254: Symbolic Logic is an introductory course in the formal techniques of argument analysis and evaluation. When you have completed the course you should be able to:

  • symbolize English sentences and arguments in the symbolic notation of sentential logic and monadic predicate logic;
  • use truth tables to determine whether arguments in sentential arguments are valid or invalid;
  • use proofs to show that arguments in sentential or predicate logic are valid;
  • use natural interpretations and model universes to show that arguments in predicate logic are invalid.

Evaluation

The final mark in Philosophy 254: Symbolic Logic will be based on grades on the three pieces of written work specified below, plus the exam. To receive credit for this course, you must submit every assignment using the drop boxes on the course home page, receive an average grade of 50% on this work, and receive a grade of at least 50% on the final exam. All assignments are graded out of 100%.

Assignment Due % Toward Final Grade
Assignment 1 This exercise is to be written after you have completed Unit 6. 15%
Assignment 2 This exercise is to be written after you have completed Unit 9. 20%
Assignment 3 This exercise is to be written after you have completed Unit 16. 25%
Final Exam The final examination will cover the entire course. It is a three-hour examination, to be written under formal examination conditions, with no notes or books except a small dictionary. Questions will be of the same sort as those in the exercise sections of the units, so the best way to prepare is to be sure you can confidently answer all the questions in the exercise sections. 40%
