The Virtual Linguistics Campus
This introductory E-Lecture about sentence semantics introduces the main principles and the central mechanisms involved in propositional and predicate logic. Additionally, it shows how entailment relations can be defined and applied and how the principles of quantification can be combined with predicates. .
SEM120 – Sentence Semantics
Thanks sir I loved a lot.
I love this channel and I love your videos. Great work!
Thank you so much!
Is this a discrete maths lesson or English grammar lesson.
whatever this is, this is really good.
I am amazed with this Professor!
woow, such a nice video, thanks
At 21:00 the statement "No linguists are bald" should be represented "~(Ex)(Linguist(x) & Bald(x))" or alternatively "(Ax)~(Linguist(x) –> Bald(x))".
The sentence "~x(Linguist(x) –> Bald(x))" appears to mean "Not every linguist is bald", which leaves open the possibility that there are bald linguists.
Also, "~(x)(Person(x)–>Like(x,Mary)" and "~(Ex)(Person(x) & Like(x,Mary))" do not both mean "Nobody likes Mary." The first means "Not everyone likes Mary." The second means "Nobody likes Mary." Someone could like Mary and the first would still be true.
All these lectures are wonderful. I wonder, though, how 'introductory' they are. For me with prior background in virtually all of the micro-topics, the lectures are a practical and grounded introduction to the linguistics approach itself: concepts such as economy of theory, sentence meaning as the possible primitive of meaning, etc. These lift up and organize the examples into a panoramic perspective — that for me is the introduction. I do not think I would have been able to absorb such meta-linguistic statements 20 years ago. What could have allowed me to do so? Perhaps a constant reference to a full-bodied live examples of meaning in action.

Great illustration Thank you very much
What an amzing presentation to the so called Semantics. I always love the way you explain the lesson with such an easy way. I am from Algeria and we are in need to such Professors like you
