The course will employ a variety of instructional methods to accomplish its objectives, including some of the following:
There will be two hours of lectures each week, with time allowed for questions; there will also be two hours of discussion of the exercises and assignments. Emphasis will be upon obtaining a working knowledge of most of the topics covered
- The Nature of Logic and Philosophical Argument
- Types of Argument – Inductive and Deductive
- Validity and Soundness
- Practice with Valid and Invalid Deductive Arguments
- Truth functional connectives
- Logical forms and substitution instances of these forms
- Truth tables
- Formal deduction for propositional logic
- direct proof
- indirect proof
- conditional proof
- Formal deduction for predicate logic
- universal instantiation and elimination
- existential instantiation and elimination
- Premise-free proofs for tautologies
- Inductive generalizations
- Inductive analogy
- Statistical syllogisms
- Hypotheses about causes, and scientific reasoning
Successful students will be able to:
- Distinguish the basic elements of arguments and recognize the different types of arguments.
- Symbolize natural language statements in the language of propositional and predicate logic.
- Identify logical relations among statements; and analyze logically complex statements into their truth- functional or quantificational components.
- Distinguish valid deductive arguments from invalid ones.
- Use truth tables and formal proofs to analyze the logic of arguments and to assess their adequacy.
Evaluation will be based upon course objectives and will be carried out in accordance with Douglas College policy. The instructor will provide a written course outline with specific evaluation criteria at the beginning of the semester.
Any possible combination of the following which equals 100%:
(No one evaluation component within each category may exceed 40%)
|Midterm tests||20% - 60%||Two 20% tests 40%|
|Quizzes and short assignments||0% - 40%||Ten 2% quizzes 20%|
|Final exam||20% - 40%||Final exam 30%|
|Instructor's general evaluation
(may include attendance, class participation,
group work, homework, etc.)
|0% - 20%||Attendance/
