## Distribution

Any term that makes a claim about the entire class of Ss is said to be distributed. The concept of distribution applies to the terms in all categorical propositions -- A, E, I, and O. We need to learn the rules for telling whether a given term is distributed or undistributed.

Distribution of subject terms

Distribution of predicate terms

Two warnings about distribution:

1. Unlike quality and quantity, distribution is not a feature of the proposition as a whole. It is a feature of its terms.

2. It is only when a term is used as the subject or the predicate of a proposition that it acquires a distribution, for only then is it being used to make a statement about all or some members of a given class.
