Course Description
An introductory general education course focusing on the use of arguments both in ordinary discourse and the academic disciplines within the humanities, social sciences, and natural sciences. The course is split between informal and deductive/formal logic. The emphasis for informal logic will be on its role for the basic learning skills of fallacy identification, written communication (reading/writing), and then bringing these skills to bear in practical ways. The emphasis for deductive logic will involve truth tables, categorical logic, and propositional logic, including proofs. Recommended for all humanities, social science, business, and natural science majors and those planning to transfer to a four-year college or university. Transfer Credit: CSU; UC. C-ID: PHIL 110.C-ID: PHIL 110.
Course Level Student Learning Outcome(s)
- Identify and explain the structure of deductive and inductive reasoning.
- Demonstrate the ability to apply formal logic methods including translation, truth functional connectives, truth tables, propositional/sentential logic, and proofs/natural deduction.
- Apply formal semantic concepts such as validity, entailment, logical equivalence, and others.
- Explain and identify common informal fallacies such as ad populum, straw man, slippery slope, and false dichotomy.
Course Objectives
- 1. Identify deductive and inductive argumentation and know the differences.
- I Formal Logic:
- I. 1. Translate natural language into the symbolic language of truth functional logic.
- I. 2. Analyze the structure of arguments, including the distinction between formal and informal arguments, as well as distinguish premises from conclusions.
- I. 3. Design truth tables to test for semantic concepts such as entailment and logical equivalence.
- I. 4. Utilize truth-functional connective in truth tables, proofs, and translations.
- I. 5. Employ key rules of inference as part of proofs in sentential logic.
- I. 6. Identify necessary and sufficient conditions, tautologies, and contradictions.
- II Informal Logic:
- II. 1. Explain and identify the most common forms of informal fallacies.
- II. 2. Analyze arguments for strength and cogency.
- II. 3. Distinguish the parts of an argument.
- II. 4. Demonstrate the skills and practices that go into deciding whether to accept, reject, or withhold judgment on a claim.
- II. 5. Analyze, assess, and evaluate the credibility of news media, internet sources, and/or other real-world sources of arguments.

Reading Assignments
Reading assignments will primarily consist of book chapters. They may also include additional articles, external links, interaction with the written work of other students, and the reading necessary for independent research.
Writing Assignments
Tests and quizzes may require essay answers. Instructors should include one writing assignment which may be an argumentative essay or other substantial writing assignment, such as identification and explanation of fallacies found in a writing sample.
Out-of-class Assignments
In the formal logic section this may include formal logic exercises, truth tables, and proofs. For the informal sections this may include finding real-world examples of fallacies, analyzing natural language arguments, media, or other tasks.
Demonstration of Critical Thinking
Read and analyze texts. Exhibit critical thinking during class discussions about logic, valid and invalid premises, audience, purpose, persuasive techniques, philosophical stance, and other elements of sound argumentation. Complete truth tables and proofs.
Required Writing, Problem Solving, Skills Demonstration
Discussion forum posts, and argument analysis. One writing assignment, such as fallacy identification and explanation for a sample source, or argumentative essay.
Eligible Disciplines
Philosophy: Masters degree in philosophy OR bachelors degree in philosophy AND masters degree in humanities or religious studies, OR the equivalent. Masters degree required.
