How to use Truth Tables | Symbolic Logic Tutorial | Attic Philosophy

Truth tables! These are a key tool for beginning logic. They help us calculate truth values for sentences and allow us to test arguments.

This is part of a series of videos introducing the basics of logic. If there’s topics you’d like covered, leave me a comment below!

How has this video not received more views? Hands down the best explanation I've seen. Thank you so much.

wonderful video! so clear and understandable when you say it! My professor makes this seem so much more complicated than necessary. for the american viewers the symbols are different so you'll have :
~ - not
. - and
v - or
) (horseshoe) - if, then
(triple bar) - iff
Thanks for making this video!

This is a really helpful video, thanks so much for making it. I think there is a mistake when you stick together the truth tables for the five basic logical connectives around 10:01. The third row of the first column should read F T, rather than F F.

[nickhann]

Incredibly well explained. Thank you!!

Excellent introduction! Small error at 9:29 in your summary table : second line from bottom the truth values of p and q should read F T and not F F.

[patrickjensen]

Do you have anything on the "direct method" where the conclusion is stipulated false and the premises true (??) - see, that why i need it ;)

You make me realize how bad my professor is at teaching logic. 😂

[carlstoffels]

You have a mistake in your truth table which demonstrates all of the p, q connectives. You say: t-t, t-f, f-f and f-f. The problem is: f-f on the third line which should be: f-t. Cheers!

So how do we apply this to every day life

[timothywise]

This video provides absolutely no value if you cannot relate it’s usage to a real world sentence! Don’t worry, you’re not the only one failing the viewers!
