Discipline: Philosophy / Humanities

Course Description: Logic is the philosophical study of reasoning, argumentation, inference, validity, and the principles by which conclusions follow—or fail to follow—from premises.

This course introduces students to both traditional and contemporary approaches to logical reasoning. Students learn to determine whether their conclusion is actually supported by its premises. The course moves from basic argument analysis into deductive and inductive reasoning, informal fallacies, symbolic logic, and finally the practical use of logic in contemporary life. Students will apply logical reasoning to:

  • Everyday arguments
  • Advertising
  • Politics
  • Religion
  • Ethics
  • Social media
  • Scientific claims
  • News reporting
  • Academic writing
  • Professional decision-making

Course Learning Outcomes: By the end of the course, students should be able to:

  1. Define logic and distinguish arguments from nonarguments.
  2. Identify premises and conclusions.
  3. Distinguish deductive from inductive reasoning.
  4. Evaluate arguments for validity, soundness, strength, and cogency.
  5. Construct logically coherent arguments.
  6. Identify common formal and informal fallacies.
  7. Translate simple arguments into symbolic notation.
  8. Construct and interpret truth tables.
  9. Recognize ambiguity, equivocation, and hidden assumptions.
  10. Apply logical reasoning to real-world problems.
  11. Distinguish logical validity from rhetorical persuasiveness.
  12. Develop habits of disciplined and intellectually responsible reasoning.

Final Critical Reasoning Project

Students select a real-world argument and conduct a complete philosophical analysis.

Possible Subjects

  • Political argument
  • Religious argument
  • Scientific controversy
  • Advertisement
  • Social media controversy
  • Ethical argument
  • Artificial intelligence claim
  • Health claim
  • Environmental argument
  • Workplace policy
  • Relationship conflict

Students must:

  1. Identify the central conclusion.
  2. Identify the premises.
  3. Identify explicit and implicit assumptions.
  4. Determine whether the argument is deductive or inductive.
  5. Evaluate validity or inductive strength.
  6. Identify any fallacies.
  7. Evaluate the quality of the evidence.
  8. Construct the strongest possible counterargument.
  9. Respond to the counterargument.
  10. Provide a final assessment.

Optional Final Creative Project

The Great Philosophical Debate: Students choose a controversial proposition such as:

“Artificial intelligence will improve humanity.”

“Free speech should have no restrictions.”

“Religion is necessary for morality.”

“Social media does more harm than good.”

“Humans have free will.”

Each must construct:

  • A thesis
  • Three premises
  • Supporting evidence
  • A counterargument
  • A rebuttal
  • A concluding argument

The students then give their assignment to a different person who then evaluates the quality of the reasoning, rather than which side they personally support.

Additional Creative Option

The Logical Fallacy Deck: Students create a 22-card Logical Fallacy Deck modeled loosely on an archetypal or tarot structure.

Possible cards include:

  1. The Ad Hominem
  2. The Straw Man
  3. The False Dilemma
  4. The Slippery Slope
  5. The Bandwagon
  6. The Appeal to Authority
  7. The Appeal to Ignorance
  8. The Circular Argument
  9. The Red Herring
  10. The Hasty Generalization
  11. The Equivocation
  12. The False Cause
  13. The Loaded Question
  14. The Appeal to Emotion
  15. The No True Scotsman
  16. The Tu Quoque
  17. The Genetic Fallacy
  18. The Composition Fallacy
  19. The Division Fallacy
  20. The Moving Goalposts
  21. The Anecdotal Fallacy
  22. The Sound Argument

Each card should include: Name → Definition → Symbol → Example → Why It Fails → Corrective Strategy
