Logic 101 (#34.5): Biconditional Introduction and Elimination

Показать описание

Biconditional introduction is a rule of inference in sentential logic that says if you know that p implies q and q implies p then you may conclude p if and only if q.

Biconditional elimination is another rule of inference in sentential logic that says if you know p if and only if q, you may conclude both p implies q and q implies p.

This stuff really does give a new meaning to the old advice to "mind your P's and Q's"

Biconditional? More like "bye ignorance", because these videos are outstanding at conveying information!

Despite most of your videos being super helpful this one was not and I would like to recommend that if you ever decide to redo this then you should do some examples to show how the rules work practically.
