"As a sophomore who had heard nothing but horror stories about the LSAT's logic section and philosophy classes in general, I was very nervous that I wouldn't catch on to logical reasoning and all its components. The tutorials catered to all of my learning styles.  I was able to listen and watch the video tutorials, and I was able to quiz myself.  Although the LSAT is a few years away, I will be using your tutorials to keep up with my logical reasoning skills."

- Chandra P.

“I took logic in college many years ago and have enjoyed the refresher. In a media environment where civil public debate has been replaced by angry name-calling, your tutorials have reminded me just how rare and precious a good argument really is.”

- Harold D.

“We’re home schooling our kids in the classical tradition, and instruction in logic and reasoning is part of our curriculum. Our 14 and 16 year-old sons have watched all your tutorials and worked through all the quiz questions, and they’re looking forward to more. Thank you so much for this resource.”

- Sherri J.

“Dear Kevin: I just wanted to let you know that I took the LSAT last month and was very happy with the result. I know your tutorials aren’t specifically aimed at the LSAT but I can testify that the general concepts and skills you teach were a great asset and helped me approach the test with more confidence. Thanks!"

- Cory L.

“Ack! I can’t turn off my fallacy radar! I feel like that kid in the Sixth Sense, except I see fallacies everywhere instead of dead people.”

- David B.

“Your videos are phenomenal, and most importantly to me, absent of any obvious agenda or bias, other than teaching the straight tools of logical thinking. Whichever way a bias or agenda ends up swinging in a person's mind, I think that it is best for society if it sits on top of logical core.”

- Robert B.

1. Basic Concepts in Logic and Argumentation 
This course introduces basic concepts that are essential for logic and argument analysis. Later courses will assume that you're familiar with the difference between valid, strong and weak arguments, and the distinction between properties of arguments that turn on the truth or plausibility of the premises, and properties of arguments that turn on the logical relationship between premises and conclusions. The last section discusses deductive versus inductive arguments and how these terms relate to the concepts of valid, strong and weak arguments introduced earlier, and the relationship between inductive reasoning and scientific reasoning.

Part 1: What is an Argument?
     1.1 Definition of an argument (4:17)
    
 1.2 Definition of a claim, or statement (4:25)
     
1.3 Definition of a good argument (I) (3:59)
    
 1.4 Identifying premises and conclusions (5:34)
       
Part 2: What is a Good Argument?
     2.1 The truth condition (6:30)
  
   2.2 The logic condition (5:49)
     2.3 Valid vs invalid arguments (5:30)
     2.4 Strong vs weakarguments (6:38)
     2.5 Definition of a good argument (II) (1:58)

Part 3: Deductive versus Inductive Arguments
     3.1 Deduction and valid reasoning (2:18)
    
 3.2 Induction and invalid reasoning (1:41)
     
3.3 Induction and scientific reasoning (9:42)

2. Basic Concepts in Propositional Logic 
You can't get very far in argument analysis without learning some basic concepts of propositional logic. Propositional logic deals with logical relationships between statements that depend only on their truth-values (whether they're true or false). It is here where we introduce the concepts of contradiction and consistency, which are fundamental to logic. We also look at the semantics of compound claims, and we spend a lot of time on so-called conditional claims -- claims of the form "If A then B". Being able to understand and reason with conditional claims is a vital skill in logic. If there is one skill that is essential to master for the LSAT (the Law School Admission Test), it's the ability to reason with conditionals.

Introduction (5:56)

Part 1: Compound Claims
     1.1 Conjunctions (A and B) (2:23)
     
1.2 Disjunctions (A or B) (3:54)
     1.3 Conditionals (If A then B) (7:02)

     2.1 Contradictories (not-A) (2:34)
    
 2.2 Contradictories vs. contraries (3:04)
     
2.3 Contradictions (A and not-A) (3:50)
     
2.4 Consistent vs. inconsistent sets of claims (5:04)

Part 3: Contradictories of Compound Claims
     3.1 not-(not-A) (2:19)
     
3.2 not-(A and B) (2:57)
     
3.3 not-(A or B) (1:51)
    
 3.4 not-(If A then B) (3:47)

Part 4: Ways of Saying "If A then B"
     4.1 A if B (2:49)
     
4.2 A only if B (3:34)
     
4.3 A if and only if B (2:28)
     
4.4 A unless B (2:00)
     
4.5 The contrapositive: If not-B then not-A (3:24)
    
 4.6 (not-A) or B (4:35)
    
 4.7 Necessary and sufficient (4:42)

Appendix: Categorical Claims and Their Contradictories
     1. Categorical vs propositional logic (5:47)

3. Common Valid and Invalid Argument Forms 
This course introduces some of the most common argument forms that use "A or B", "If A then B", "All A are B" and "Some A are B". The goal is to be able to recognize these forms when they appear in ordinary language, and know which forms are valid and invalid. These forms have been studied and taught for centuries, which explains the prevalence of latin names (like "modus ponens") in this literature.

Part 1: Argument Forms Using Disjunctions (A or B)
     1.1 Valid forms using "OR" (2:42)
     1.2 Invalid forms using "OR" (2:42)

Part 2: Argument Forms Using Conditionals (If A then B)
     2.1 Modus ponens (3:53)
     2.2 Modus tollens (1:49)
     2.3 Hypothetical syllogism (3:50)
     2.4 Affirming the consequent (3:28)
     2.5 Denying the antecedent (3:35)

Part 3: Argument Forms Using Generalizations
     3.1 Valid and invalid forms using "All" (2:41)
     3.2 Valid and invalid forms using "Some" (2:08)

4. Fallacies 
There is a small industry devoted to identifying and classifying fallacies of reasoning. A comprehensive list of fallacies would run into the hundreds. This course introduces the concept of a fallacy and discusses some common fallacy types, but it in no way aims to be comprehensive. Instead the focus is on how any given fallacy can be understood using the basic concepts of argument analysis introduced in earlier courses. The only classification used distinguishes logical or formal fallacies (see course 3), fallacies that arise from false or implausible premises (see Part 2), and fallacies that are best understood as violations of one of the necessary conditions for having a rational argument at all (Part 3).

Part 1: Introduction
     1.1 What is a fallacy? (4:35)
     
1.2 Categorizing fallacies: pros and cons (5:04)
     1.3 The rules of rational argumentation (4:09)

Part 2: Some Important Content Fallacies
     2.1 Ad hominem (abusive) (10:32)
     
2.2 Ad hominem (guilt by association) (7:10)
     
2.3 Appeal to hypocrisy (tu quoque)) (3:43)
     
2.4 Appeal to popular belief (or practice)  (4:25)
     2.5 Appeal to authority (7:43)
     
2.6 False dilemma (8:46)
     
2.7 Slippery slope (8:12)

Part 3: Fallacies that Violate the Rules of Rational Argumentation
     3.1 Straw figure (3:41)
     
3.2 Red herring (3:43)
     
3.3 Begging the question (narrow sense) (6:28)
    
 3.4 Begging the question (broad sense) (10:32)

5. How To Write a Good Argumentative Essay 
It's a sad fact that fewer and fewer students are exposed to basic principles of essay composition, and even fewer are exposed to principles of argumentative (or persuasive) essay writing. In this tutorial course I present the key concepts of argumentative essay writing that I teach my own philosophy students.

These tutorials make use of concepts and techniques developed in my "Basic Concepts in Logic and Argumentation" course, and I recommend that they be viewed after exposure to that material, but they can also be profitably viewed on their own.


Introduction (4:11)

Part 1: Guidelines for Structuring an Argumentative Essay
     1.1 A Minimal Five-Part Structure (9:50)
     1.2 Writing the Introduction (7:12)
     1.3 Writing the Conclusion (2:38)

Part 2: A Sample Essay with Some Problems (and Strategies for Fixing Them)
     2.1 The Essay: "Should Teachers Be Allowed to Ban Laptops in Classrooms?" (1:06)
     2.2 Analysis: The Introduction (3:02)
     2.3 Analysis: The Main Body: First Argument (4:03)
     2.4 Analysis: The Main Body: Second Argument (1:46)
     2.5 Analysis: The Main Body: Third Argument (4:01)

     2.7 Analysis: The Conclusion (6:57)
     2.8 The Essay: Improved Version (1:39)
     2.9 The Essay: Improved Version with Commentary (8:33)
