What Makes a Sentence True or False? Predicate Logic

What kind of logic can we find inside sentences? How do we calculate the meaning from what we hear? In this week's episode, we talk about predicate logic: why we need it, how it differs from sentential logic, and how we can combine it with quantifiers to capture the full meaning of our language.

This is Topic #50! Wow.

This week's tag language: Albanian!

We also have forums to discuss this episode, and linguistics more generally.

Looking forward to next week!

Why don't you teach at my uni, but instead I have to listen to these tedious classes I do every week... It is important how a topic is taught, and you do it brilliantly, clearly and precisely. Thank you for these videos!

This video needs to be at the top of the search results. If it was, I would have saved a lot of time searching for this info. A lot of the videos on here are way to wordy and the speakers think too highly of themselves (they like to hear themselves talk). This video actually captures what is important and isn't annoying. Thank you for putting this video together.

Very welll done! Thank you so much! Before your video, I had difficult time understanding Gottlob Frege contributions to Semantics, once Frege is the Father of Predicate Logic.

Predicate logic is awesome! THank you very much for showing it to us though this video! ☺

This is very helpful for studying my Discrete Structures in Computing course. Thank you!

So happy abt the Buffy references! ☺️☺️

All of the variables and the symbols makes language looks like math. It's hard for me to grasp these explanations, especially the predicate logic. Anyway, are these logics part of semantics or else? Thank you. ^^v

Angel AND linguistics!! This totally made my day. Throw in a little Buffy, and it's my best day ever ;P

[ghofrant]

AMAZING as always!! thank you very much!!

Thanks, Moti. This was interesting, and as usual I learned something, although I must admit much of this was over my head; I had no idea this sort of thing existed before watching this video.

On another topic, is it just me, or is the use of the word "an" disappearing of late? I have noticed that many people who otherwise seem reasonably well educated routinely say things like "a apple, " often in contexts where I would not expect this. Newscasts, for example.

Isn't the correct formulation in the example at time 6:56: (Fx ^ Oxy) ^ Hy) instead of: (Fx ^ Oxy ^ Hy) The conjunction can´t scope over another conjunction? Just a question since i thought i learned it differently : )
Fantastic videos btw.

Hey, can anyone help me with this translation, please?
"To pass the SEG exam the students have to obtain grade 5 to all the three evaluation forms: laboratory, test, final exam. If one of these grades are below 5, even if the others are higher, the student fails."

"Logic gets us closer and closer to understanding what speakers must know, when they know the meaning of words" ....seems to me all our governments need Boards of Logic.

The following sentence is false.
The previous sentence is true.

so what did you learn? "BUNNIES!"
