Mr. Rose told us about Formal Extensional Semantics, which is the study of how words in a sentence come together to form meaning.
NOTES (thanks to WL — to be completed):
- This stuff might be slightly out of date
- Semantics is about meaning. This is important, because the whole reason we use langage is that it has meaning.
- The form that sentences take is based on their meaning
- To know the meaning of a sentence is to know its truth conditions (when it is true)
- (1) There is a bag of potatoes in my pantry.
- Truth conditions: what must be true about the world for this sentence to be true
- Awkwardness of studying objects made of words using words. Distinguish between object language (language of the object under study) from metalanguage (langauge used to study the object).
- The sentence “There is a bag of potatoes in my pantry” is true if and only if there is a bag of potatoes in my pantry.
- Quotes signify element which is being studied
- Problem: It’s just unsatisfactory to say that the sentence “_______” is true iff _______. Doesn’t explain anything or give predictions.
