Chapter Six:
Predicate Logic: Quantifiers and Categories

In this chapter, we turn back to our formal language with names and predicates. But we add one small but terribly important element: the ability to talk about quantities. In English, this just means the words "all" and "some". This little wrinkle will take some time to develop.
