Thank you so much for saving my grade!!!

A professor takes a chance at the students expense by trying to explain why these rules are valid, and why they must be done. When a child is learning multiplication for the 1st time, they dont understand what they're doing but memorize the times tables. Eventually as they grow they will understand. This is the same, the difference is you do not learn logic as a child, but as an adult, but the learning should be the same. Logic is math. Trying to understand why and what it is, wont help early on

3. This is how it should of been defined: the "IF-THEN" (i.e. p-->q, if p then q, p implies q, or q if p) Truth Table. To say that p-->q means that IF p is true, THEN q must also be true. The p-->q statement is true until proven false. The statement 2+1=5 --> pigs can fly is true, precisely b/c p is not true. Nothing is promised in the case p not being true so the entire p-->q statement has not been shown to be false.

Note: I made a bunch of comments and removed them b/c after further research I realized I was wrong.

1. The "tricky one" is only tricky b/c the definition is poorly worded. Also the way she words it is very confusing and even has contradictions. Every time she said "if p is true then p implies q is true if q is also true." it sounds confusing b/c by "p implies q" she means the entire p-->q statement. In other words if p is true then the p-->q statement is true if q is also true.

Thanks for the video, but damn this stuff racks my brain...

Philosophy exams are hard >_>

@merlock101 Lol.

[merlock101]

@xxFortunadoxx I'm pretty sure that's a logical fallacy. Though my teacher didn't help me remember which one.

[snookums729]

Okay, after a few tries...I get what they are saying. What I don't get is WHY everything has to be so over-complicated and round about and think and re-think....for heaven's sake...simplify life and just spit it out! A few shades of gray are fine in life but this sort of thing just implies that there are no other colors BUT gray....Stop dancing around the room and just walk straight across the floor to the other side!..lol

@Jibberwockee Sadly, most philosophy teachers are horrible teachers because they don't know how to teach properly to students.

[RJonStreetz]

Perfect INTRODUCTORY video!!!

[Jibberwockee]

After seeing this and realizing how simple it is I must conclude that my professor, while undoubtedly brilliant, is nonetheless an awful teacher. His explanation was incomprehensible.

Thank you for your easy to follow explination, I understand it now when reading my profs notes I had no idea but now its easy and will do good on the test!! THANK YOU!!

thanks

[peterATIAMDlife]

i prefer the books notation.

[HOODYWOODRECORDS]

Wha???? I'm going to go bash my head against a wall and then come back and watch this again maybe after doing that I'll get it?

[lthp]

The very nature of 'if' is that when a false antecedent is assumed true, then the condition can't be proven false since It's a hypothetical scenario. If p is true on the other-hand, then we are back in reality and the accuracy becomes accountable and the q must follow as a result of p- so q cant happen if p didn't happen. Somebody please enlighten me where possible, this is my initial understanding thanks to this video.

[deanthegreat]

In the and statement, If there is a false in them its false

or statement If they are both false its false

if then statement if q is false its false, except if they are bothe false its true

if and only if: if there is a false in them its false if they are both false its true

[moe80ca]

please where to find examples for this truth table i got no book can any one message me those examples nd be my hero?

[deanthegreat]

I got confused where it said "it is true, but I changed that to say "result" and now feel more confident.

[LPEREZ503]

why do geometry gotta be soo confusin ?

[vapid1000]

I can see how this can be confusing. But once you understand, its actually very easy.

[IcedLipGloss]

THANK YOU SOOOOO MUCH FOR THIS! My idiot teacher "taught" us this today and I was SO lost. And he has a thick accent so its sometimes hard to understand him. I wouldv'e gone to tutoring but he only tutors during 9th period, and I have class then. Once again, thank you a ton for this! I'm finally starting to understand this!

[ASHnKay10]

Hope you did well in ur class:)

[EastSydeHoods]

@MazzyDreamer LMAO!!!

The if-then explanation was not clear at all - the explanation wasn't logical
