Bro you just saved me! Have a test in 2 hours. Learned more in these few min then the whole class

I've never understood symbolic logic until I watched this video. Thanks for the upload! Math with sentences... huh..

It has been 30 years since I attended a Symbolic Logic class. I find your style of explaining the layout refreshing.
Thank you for your work.

Literally the only person who explains this well. Thanks for help!

Confusing example 6 at 3:00
"I will jump off if and only if you do"
Makes it sound like "you will jump off if and only if I do" is the same equivalence - whereas they are subtly different. More accurate is
_"I will jump off if and only if you have"_ or
_"I will jump off if and only if I'm convinced you will do so"_

"If and only if" is sometimes a confusing concept for beginners, so we probably need a better example for it.

Dear TeachPhilosophy.  Thank you for doing the work of recording this!!  I am a teacher of philosophy at a high school, and I want to teach a much more robust unit on logic next time around.  This is giving me a way to learn myself what I find difficult to learn on my own (I have never taken any classes on philosophy or learned logic from any teacher...all self-taught. And I was never good at math, so the symbolic part does not come as easily). Rather than play all your videos for my students, do you mind if I (having given you full credit and linked them to your videos) use the scope and sequence, and even some of the examples you use in my lessons?

I'm doing first year civil engineering, i've seen some of these symbols, such as the Tilde, wedge, and horseshoe in my maths textbook in year 12. When I first saw these questions as part of one of my assignments for university, I had ill-will towards it, as I would have preferred to do integral calculus as opposed to symbolic logic to enhance my logical thinking skills. Moreover, I felt that it was irrelevant to a maths course. But you clearly enjoy it, and that's enough motivation for me to want to enjoy and learn it. I'll smash your videos out instead of lecture slides :p.

Sorry for the lengthy comment, cheers mate!

Thanks for saying "tildee"- that's the way I learned it years ago. Now it's just weird to say "til-duh". ;)
