Introduction to Logic (Lecture 03, Disc 01)

  • Apr 27, 2014 · 4:00 PM

Dear Friends of Objectivism, 

This event is a continuation of Dr. Leonard Peikoff's audio lecture course: Introduction to Logic. To keep pace with the group, participants are required to listen to the remaining portions of each of the lectures on their own time. 

In order to attend and participate in the discussion after each lecture, participants must purchase the downloadable version through The Ayn Rand Institute (ARI), unless a copy of the course is already owned.

Couples (or families) are only to required to purchase one complete set of lectures.  

We anticipate that our meetings will be scheduled approximately every two weeks. There are no additional charges to participate in the study group, although donations for the organizer’s time and the use of the facility would be appreciated. 

The complete lecture series (consisting of 27 hours) can be purchased/downloaded from the Ayn Rand Institute eStore: $9.24

In agreement with The Ayn Rand Institute Bookstore, participants are required to provide proof of purchase of the lecture series prior to attending our meetings. Proof of purchase can be provided by email, by bringing a printed receipt or your set of the original CDs.

If you are willing to donate some refreshments such as nuts, cookies, drinks or fruit, please call or E-mail me. 

We look forward to seeing you!

Since this course is being hosted in a private home, the host has requested that we meet new members at a public establishment prior to providing the address. We will be organizing dinner meetups, which will provide new members with the opportunity to get to know us.

Introduction to Logic 

Course Description: 

This course (with exercises) covers the standard topics taught in introductory courses in Aristotelian logic. It defines the principles of valid reasoning, and discusses prevalent logical fallacies. It formalizes the steps by which one derives conclusions from premises, and it provides a methodology by which to evaluate one's own thinking processes. (Each lecture includes a question period.) 

1. Basic Logical Theory 
The cognitive role of logic. The laws of logic and their validation. Logic vs. mysticism and subjectivism. Logic and reality. 

2-3. Informal Fallacies 
Twenty-two common fallacies, including: the appeal to authority, ad hominem, ad populum, ad ignorantiam, begging the question, equivocation, composition, division, misuse of the mean and false alternative. 

4. Introduction to Deductive Reasoning 
The nature of deductive argument. Validity and truth. Mixed and pure hypothetical arguments. Alternative arguments. 

5.-6. The Aristotelian Syllogism 
Categorical propositions. Immediate inference. Rules of syllogistic validity. Analyzing arguments in ordinary language. 

7-8. Definition 
The cognitive role of definitions. Genus and differentia. The method of formulating valid definitions: five Aristotelian rules of definition. Definitional fallacies. 

9-10. Inductive Generalization 
Induction vs. deduction. Induction by simple enumeration. Experimental induction: Mill's methods of discovering causal connections. Major inductive fallacies, including: hasty generalization, oversimplified generalization, post hoc. The justification of induction. The argument from analogy.
