Truth Tables Tutorial (part 1) 

Brian Stonelake hey I appreciate the reply ! I think I’ve thought of a different answer let me know what you think about it . So I also realized that just because p and q are both true , in the real world it does not mean that p implies q. You could just have a situation where p is true Independently of q. So the way I reconciled this was thinking of it in more mathematical terms as in “does it satisfy the condition “ so if p is true and q is also true , it does indeed satisfy ‘if p then q’ because when p is true q must be true for this to work . And when p is false , any truth value of q would work because the condition only concerns when p is true .. and the point of these truth tables is only to decide validity , not soundness so in a way some of the Ts can be thought of as place holders as in we’ll call it true since it does not invalidate the argument . When you think about it the only situation that would truly invalidate ‘if p then q’ is specifically when you have p but q is false . Haha that’s my thoughts on it

oh thank god someone put it into words! this was my sticking point too. I thought I was just dumb because I skived maths in high school.

I personally find this difficult to explain also but I believe it is this way: Since the condition is already false, there is no more condition for the q so it is independent. It becomes “vacuously” true nonetheless since Q is true

So it’s only false if the condition is negated?

It's asking to write a T if either Q or -P has a T in that column.

Freaking me to. Me too. Like it’s the best for someone who thinks logically.

I did cry

RIGHT

true its a T bro

I’m lost

yessss i should have youtubed it forever ago lol

I felt that frustration on a spiritual level omg

i’m telling you, on the brink of breaking down.

Omg!!! Learned more in ten minutes than in a week of logic class. 🎉

Just got my results and I got a 92. This is honestly the best video ever made. Thank you thank you thank you!!

@@angeldo8546 omg 92 😱😱 wowwwwwwww

omg samee

I feel u

Sense*

Aye Bae I need a tewter u finna help me out?
