เข้าร่วมเมื่อ 16 มี.ค. 2020
Philosophy prof at a college near California's Sierra Nevada. I try to make fun, high-quality philosophy videos for college students, homeschoolers, or anyone wanting to learn about philosophy.
Do you teach logic or philosophy? These videos are for you, too. Feel free to assign in your courses!
Teaching yourself logic? Pick up Paul Herrick's Introduction to Logic (Oxford University Press) and work through it together with the logic videos. Specific chapters are cited in each logic video description.
But the channel covers more than just logic! See the playlists:

Natural Deduction Proof Example
มุมมอง 2.1K3 ปีที่แล้ว
A simple example of a natural deduction proof using basic inference rules: simplification, conjunction, disjunctive syllogism, modus ponens, modus tollens, and addition. This process is called natural deduction and amounts to a proof of validity. Such proofs are a central feature of symbolic logic in philosophy. Your textbook may use different symbols and different names for the rules of infere...

How to Make a Partial Truth Table | Determine Validity
มุมมอง 3K4 ปีที่แล้ว
Make a partial truth table to determine whether an argument is valid in symbolic logic (propositional logic, sentential logic.) Testing for validity with a full truth table is too slow. Instead, learn how to make a partial truth table. Note: Your textbook may use different symbols for the connectives. It doesn't matter!
