truth table applications PHIL 013AB
An eleven-minute video on the things you can do with truth-tables. Covers tautology/contradiction/contingent, implication and equivalence, and argument validity.
negation proof rules PHIL013AB
A video on rules for proofs with complex negations, like ~(P & Q), ~(P v Q), and ~(P -> Q).
conditional truth table PHIL013AB
A five-minute video explaining why the truth table for the conditional is the way it is.
conditional derivation proofs PHIL 013AB
A nine-minute video about conditional derivation, a new kind of rule. Listen closely for a special appearance from a duck. (Edited to add: the squeaking thing is actually a raccoon)
negated quantifier proofs PHIL013AB
A video on how to do proofs with negated quantifiers. Introduces two new rules, ~AO and ~EO, and discusses how to do proofs where you need to SHOW negated quantifiers (you have to do ID).

A video on the indirect derivation rule for proofs.
only and categorical compounds
