Modal Logic
Question
In the first booklet you write that there are difficulties with the concept of “necessarily true,” and because of that modal logic was developed. What is so problematic about the concept of necessarily true?
Answer
The problem is not with the concept itself but with its logical formalization. These matters are explained in the third book in the Talmudic Logic series, and it is hard to get into that here.
Discussion on Answer
There’s no way to read them online. Our books are only on Amazon. But I’m sure there’s also material on the internet.
Can those books only be obtained in stores, or is there a way to read them online?
