Logic: The Cashing-In
Jun 22, 2019
Concepts, though fundamental, are only tools—only means to an end. The end is the practical, productive, rational use of your mind to achieve your values, secure your survival, and enhance your life. That is the topic of this course: four classes on using concepts to think—to think in the way that reaches rational conclusions.
Thinking is in sentences—i.e., propositions. Combining theory with homework exercises, two classes contrast the logical and the illogical way to form propositions, then two classes deal with integrating propositions to reach new identifications of facts—i.e., induction and deduction.
Exercises will cover: propositions vs. pseudo-propositions; the fallacies of the stolen concept and self-exclusion; clear vs. vague, ambiguous, and crow-busting sentences; the categorical syllogism; the hypothetical syllogism; the five rules of validity; how to induce; and inductive fallacies.
