1. Logic Lecture: Introduction to Modal Logic 

Finally, finally, finally. For years I've been trying to find a good series of logic lectures on RU-vid. I must've typed the right metatag this time...Glad I did. Thanks for the creation. Through your contribution, we all benefit and in turn will be able to contribute and spread knowledge to others.

Thanks for this course! It's been a while since I've been out of school and it's nice to get a refresher course without rereading the whole book! Cheers.

Great job jason-- I love the way how many people in this world use their valuable time to educate the world--kudos to you ;)

Thanks for this lecture, Dr. Campbell! You mentioned you were a sociologist--I'm curious if you have any practical examples of applying modal logic in this field that you could share.

It's true that a lot of people get hung up on notation. Which is a shame, not only because there is much to be learned, but because the symbols arranged semantically are quite beautiful. I can see that I'm going to enjoy this series. You're subbed. Also, anyone wanting an intro book with a decent problem set should check out Rod Girle's "Modal Logic and Philosophy"

Great class and great shirt

This is clear! Great mini lecture! Thank you for your time taken to make this for us!

You are still needed

Nice! I was hoping you would cover Modal Logic!

Do you have videos on propositional logic?

Very cool, thanks for doing this.I have a background in mathematics, but I'm very curious what modal logic is and how its applied.

Very good stuff!

Hello, Dr. Campbell. What is your opinion of paraconsistent logics?

Most of the symbols that you use are pretty conventional throughout philosophy and mathematics, with perhaps the exception of the dot symbol (conjunction is usually denoted with a ^)

Thanks. Going to recommend this for learning.

Great videos!

I have deep suspicions about modal logic, and always have. I am not sure it's ontologically legitimate, and that would amount to simply illegitimacy.

Start at 2:30 you are welcome

Thank you so much.. ❤️❤️❤️

It is possibly necessary if, and, not biconditional that this video is morally logical.

www.sfu.ca/~swartz/pw/ In a university will intro on modal logic books be this difficult?

There's more than one conditional, and this is only part 1.

Thanks

thenks!

Wtf you did modal logic????? Awesome!!!!
