Philosophy of Language, Logic, and Linguistics – The Very Basics
Any starting reading list in this area is going to have its proponents and its detractors.
I would add to this list John Sowa’s “Knowledge representation : logical, philosophical, and computational foundations“. There is a website as well. Just be aware that John’s views on Charles Peirce represent a unique view of the development of logic in the 20th century. Still an excellent bibliography of materials for reading. And, as always, you should read the original texts for yourself. You may reach different conclusions from those reported by others.
