Basic Methods: We define tautology and contradiction and consider the conditions of logical equivalence and implication. Examples include DeMorgan's Laws for logic, modus ponens, and the Law of the Excluded Middle. As a final note, we introduce the Substitution Rules.

Logic: The Structure of Reason
As a tool for characterizing rational thought, logic cuts across many philosophical disciplines and lies at the core of mathematics and computer science. Drawing on Aristotle’s Organon, Russell’s Principia Mathematica, and other central works, this program tracks the evolution of logic, be

TAUTOLOGIES, CONTRADICTIONS, and CONTINGENT WFFS - Logic
In this video on #Logic / #PhilosophicalLogic, we learn about tautologies (wffs which are always true), contradictions (wffs which are always false), and contingent wffs (wffs which are both true and false depending on the situation). Then we do some practice exercises. 0:00 [Intro] 0:16

How to use PARTIAL TRUTH TABLES to find tautologies, contradictions, and valid arguments - Logic
In this video on #Logic / #PhilosophicalLogic we use partial truth tables to determine whether a wff is a tautology or contradiction. In turn, we use this method to determine whether arguments are valid. This is a much more efficient way than drawing entire truth tables. 0:00 [Intro] 0:3

3 Ways to Show a Logical Equivalence | Ex: DeMorgan's Laws
DeMorgan's Laws are two important logical equivalences. In introducing these laws, I talk about three different ways by which you can demonstrate a logical equivalences: There are truth tables, citing known laws, and testing for reasonableness. *******************************************
