Introduction to Logic (Lecture 04, Disc 01)

  • May 18, 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!

First Time Attendees: Since this course is being offered in a private home, the host has requested that we meet new members at a public establishment prior to providing the address for the classes. We will be organizing dinner meetups which will provide you with the opportunity to get to know us. Please contact Donovan for course admission details.

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.

2-3. Informal Fallacies

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.
