@13:34 "we are doing this by video, that no one will watch."

Sir, you are wrong. These videos have been a treasure trove of info, and I've come back to them multiple times since you posted them.

Thank you for your efforts!

fucking legend, computer science majors all over the world bow to you right now, my good sir! :)

After 6 weeks of class im finally starting to understand natural deduction because of you, thank you William!

You are a magician! I am in uni and this is the 3rd time I'm doing a logic course. No-one has been able to explain Natural deduction as clearly as you do. Thanks.
