2 What aspect of rational behaviour does logic (in our narrow semantic sense) refer to?
Calculations
3 Describe some of the ways in which logical connectives such as and, or, and not differ from other word types (such as names and predicates).
Words such as and, or, and not are not predicates and cannot be used as referring expressions. Logic calls such words connectives. We will learn much more about the meaning properties of these words in the next few units, but it is easy enough to see now that, intuitively speaking and as their name suggests, the main purpose of the connectives and and or is to ‘connect’ individual propositions with other propositions. (The word not functions in a somewhat different way and will be explained further in Unit 15.) The kind of meaning that is involved is structural, i.e. it deals with the whole structures of propositions and how they are related to each other, rather than with individual items within propositions, such as names and predicates. It is possible to talk of the extensions (or, more loosely, the denotations) of names and predicates taken in isolation, but it is not possible to imagine extensions or denotations for words such as and, or, if, and not, taken in isolation.
