Chapter Seven:
Predicate Logic
Semantics and Symbolization

In this chapter, we give a better definition of meaning for PL sentences. Then we can look at some more sophisticated symbolization of English into PL. The goal here is to provide a precise handle on both PL and English meaning.

Start with the introductory tutorials presented below, then print out the reference manual for this chapter (that way you'll have a concise statement of this chapter's details to refer to even when away from the computer.) Finally, and most importantly, carefully work your way through the chapter exercises.

Still don't have the Logic Font? Having problems installing it? Here's how to better display quantifiers in exercises even when you don't have the font.
