Logic: 1. Argument; Assertion; Evasions
Logic has to do with the principles of sound reasoning. We have the responsibility to be good reasoners before God in understanding how we prove religious, saving truth. We are all logicians in our daily lives, whether we think of ourselves that way or not. Join Mac Deaver in the first video of this lesson series as he delves into deduction, arguments, assertions, and evasions.
-
Logic: 2. Evasions (Cont); Syllogisms; Propositions
In lesson 2 of Logic, the discussion of evasions is continued. There are multiple evasions of the Law of Rationality, and we must take care not to fall into them in our reasoning. Towards the end of this lesson, syllogisms and propositions are introduced.
-
Logic: 3. Propositions (Cont); Distribution
What is the quality of a proposition? What’s the quantity of a proposition? In this lesson, Mac Deaver discusses the answers to these questions, class exclusion and inclusion, identifying different categorical propositions, and distribution.
-
Logic: 4. Distribution (Cont); Rules of Validity
The fourth lesson continues on the subject of distribution, discusses the analysis of categorical syllogisms, and begins to lay out the rules of validity.
-
Logic: 5. Rules of Validity (Cont); Sentence Translation
Continuing from the previous lesson, Mac Deaver discusses rules of validity, illustrates sentence translation, looks at class relationships, and discusses the exclusive proposition.
-
Logic: 6. Sentence Translation (Cont); Equivalent Propositions
In this sixth lesson, Mac Deaver analyzes negative sentences, translates exceptive sentences, and begins the topic of equivalent propositions starting with obversion.
-
Logic: 7. Equivalent Propositions (Cont); Syllogisms; Terms
Continuing the thought of equivalent propositions, Mac Deaver illustrates conversion: reversing the order of subject and predicate relationship. He also discusses contraposition, the enthymeme, and what constitutes a sound argument.
-
Logic: 8. Seven Relations; Square of Opposition
The eighth lesson considers the 7 relationships among propositions: the independence of a statement, the equivalence of statements, the contradiction of statements, the contrariety of statements, the subcontrariety of statements, the superimplication of statements, and the subimplication of statements. He also shows the square of opposition that illustrates the relationships between propositions.
-
Logic: 9. Laws of Thought
In the final class, Mac Deaver talks about the traditional laws of thought. Humans, made in God’s image, are beings of ration and reason. He discusses the law of identity, the law of excluded middle, and the law of contradiction. He also talks about the types of compound propositions, and the dilemma in logic.
