Propositional Logic Truth Trees (and, or, not)

In this video on #Logic / #PhilosophicalLogic I introduce truth trees, inconsistent sets of wffs, and rules for disjunction, conjunction, and the negation. We talk about disjunction decomposition, conjunction decomposition, double negation, negated disjunction decomposition, and negated conjunction decomposition. Then, we do an example of a truth tree. 0:00 [Intro] 0:17 [What is a truth tree?] 2:51 [Rule: Conjunction Decomposition] 4:04 [Rule: Disjunction Decomposition] 5:02 [Rule: Double Negation] 5:20 [Rule: Negated Conjunction Decomposition] 7:39 [Rule: Negated Disjunction Decomposition] 8:47 [Inconsistency and Example #1] 10:51 [Example #2] Follow along in the Logic playlist: https://www.youtube.com/playlist?list=PLDDGPdw7e6AhsNuxXP3D-45Is96L8sdSG If you want to support the channel, hit the "JOIN" button above and pick a channel subscription that suits your needs: https://www.youtube.com/channel/UCGYSfZbPp3BiAFs531PBY7g/join Patreon: http://bit.ly/2EUdAl3 Website: http://TrevTutor.com Subscribe: http://bit.ly/1vWiRxW Facebook: http://on.fb.me/1vWwDRc *--Playlists--* Logic: https://www.youtube.com/playlist?list=PLDDGPdw7e6AhsNuxXP3D-45Is96L8sdSG *--Recommended Textbooks--* The Logic Book: https://amzn.to/31h2qR8 Modal Logic for Philosophers (Garson): https://amzn.to/3dECGn4 A Friendly Introduction to Mathematical Logic: https://amzn.to/37hMYZa An introduction to Formal Logic with Philosophical Applications: https://amzn.to/3j3J9sx Hello, welcome to TheTrevTutor.
