Logical Equivalence | Symbolic Logic Tutorial | Attic Philosophy

Equivalence is another key concept in logic. Equivalent sentences 'mean the same', as far as logic in concerned. That allows us to transform sentences in interesting ways, using equivalence schemes. In this video, we'll see what equivalence is, how it's defined, and how to test for it using truth tables.

This is part of a series of videos introducing the basics of logic. If there’s topics you’d like covered, leave me a comment below!
