Distribution. This is a technical phrase in logic for the use of a term in its whole extension.
When we say all men, no men, the term men is said to be distributed, i. e. it is applied to everyone who belongs to the class, while when we say some men it is undistributed, not applied to everyone. In this the original sense of the word singulars are incapable of distribution, and so pronounced by Petrus Hispanus. Nevertheless, in many modern logical works they are said to be distributed (by myself among others) as being of necessity used in their whole extension.
Distribution is likewise a name for the methodical arrangement of a subject, viewing it under what are considered its appropriate heads. When such are species of a genus it becomes identical with division.
