Thank you, Mark! I'm doing a philosophy course from an open university just out of curiosity. But when I opened my text book and came across 'Logic' I was like 'what have I gotten myself into!' and was contemplating on giving up. Then I found your lecture series and now I feel I can get through this. You're the best!
You are saving me in this class. I was terribly lost and wasn't getting much help from my professor so I found your videos and followed along with you while I work. Thank you so much for saving me!!!
At last, explanations that make sense and are easy to understand (especially your great examples!! other teachers make it all seem to difficult ... thank you , thank you, Mark!
I have enroll into Intro to logic course, focusing into deductive logic, and I have not catch either what the professor says or a light grasp of the book... until I found these lecture videos. I had exam 1 and did not understand the subject. Then two days before the test, I watched these lectures... guess what; 100 points over 100!!! THANK YOU!
I took this 300 level logic class as an elective in my last senior semester in the engineering program, thinking it would be an easy class (no math anyway), and I was sorely mistaken. The homework assignments take longer than some of my worst engineering homework, partly due to the crappy publisher's website that we are forced to use, and the concepts are not very well-explained. Your videos may have saved the day! Thanks for posting these. You've helped me out a lot.
Thank you ! I have been stuck on the homework for this section ( pretty much over thinking it) and this video cleared it up for me. glad I came across this.
Thank you Professor Thorsby! My tuition for logic class should go to you, I got more out of watching you than lecture class. It's beginning to make sense....
How do we know what to pick as true or false or does it not matter. Like he had A,B,C as true and D,F as false could we change this to A,B as false and C,D,F as true and it still work?
I wonder if Mark Thorsby wishes that he had a Mark Thorsby in his life when took intro to logic...I can't say for sure yet, but I'm pretty sure you saved my ass...Thank you
Negation = opposite truth values Conjunction = any false hood makes it false Disjunctive = always true unless both variables false Conditional - always true unless the antecedent is true and the C is false T ) F Biconditional = both have to be true to be true
Hi Felecia, There is just one thing... the bicondition should have the following rule: "biconditional = they both have to have the same value" (whether it is true or false does not matter) Hope that helps.
These videos aren't terrible, but every 2 minutes or so its "Oh wait that's not right". It is painful to sit through some of these taking notes and numerous times throughout he makes some stupid mistake and has to retract.
