Very helpful, I understood better with your videos than my instructor thank you for posting these videos :)

Thank you. I am following all of your Introduction to Logic videos.

33:44 The main operator is the dis-junction (the wedge) and not the negation.

Jesus Christ......finally someone who knows what they are talking about and explains it clearly and easy to understand!!!....thank you very much...your a legend!!!!

I'm aware I'm commenting on a super old video, but I can not thank you enough for this explanation!

At around 37 minutes, I was confused about necessary conditions. You said Hilton isn't going to do it unless Marriott does it first, but in both statements, Hilton occurs first chronologically. After I wrote it out in the following statements, the example made sense: Sufficient condition: If H is true, then M has to be true. (Only H is required for M.) Necessary condition: If M is true, then H has to be true (but R and S might need to be true along with H before M is true). H is still chronologically prior.

Mark you are a god for posting this series

This cleared so much up for me, i really appreciate it, thank you!

Thank you, I always look at your videos before a test and it is as clear as day

You explained everything beautifully. Thank you!

34:15 - sufficient and necessary conditions

Thank you for creating this lecture. I have to have a visual to understand these questions.

Thank you so much sir... It helps me so much.. I am a student of university of Peradeniya, Sri lanka..

Thank you for your explanations, they are very helpful especially because you emphasize what is important to know for future references. If I can give some constructive criticism it would perhaps be: when going over exercise examples, maybe show both the difficult ones and easy ones.

you just got yourself a new subscriber :D Thanks a ton

Great video, I was feeling lost in class and doomed for my quiz and final. Now I have hope!!!!!

At 35:05 You gave us an example that If you put gas in your car, then you can drive. I think what you mean is put gas is Sufficient condition and Drive is Necessary condition. right? I am little bit confused there. May you help me to clarify that part? thanks in advance.

Thanks!!!

You're an excellent teacher. I'm gonna call your mom and order four more of ya..... :)

Oh, Hi Mark!

Are symbolic logic and propositional logic the same?

Why did you have the term "only if" as a conditional? In the legal system, if the Court writes: "Jane Doe v State of Missouri, pursuant to Section 104 of the Missouri Code of Criminal Procedure, the State of Missouri shall hereby do Z only if Jane Doe serves 100 years in the State Penitentiary without the possibility of parole," the logical connector "only if" is used as a biconditional and not as a conditional. Why is there a disconnect between legal logic and nonlegal logic?

It is false the Mark is a bad teacher. Thanks for posting.

Since I found your videos my grades have improved greatly. However, you move so fast and switch so quickly, i did not benefit from this video.

You are just replicating the book. No point.
