is not a collective term, whereas 'flock,' 'regiment,' and 'senate'
are. Wherein then lies the difference? It lies in this--that flock,
regiment and senate are groups composed of objects which are, to a
certain extent, similar, whereas London is a group made up of the most
dissimilar objects--streets and squares and squalid slums, fine
carriages and dirty faces, and so on. In the case of a true collective
term all the members of the group will come under some one common
name. Thus all the members of the group, flock of sheep, come under
the common name 'sheep,' all the members of the group 'regiment' under
the common name, 'soldier,' and so on.

124. The subdivision of singular terms into individual and
collective need not be confined to the names of concrete things. An
abstract term like 'scarlet,' which is the name of one definite
attribute, may be reckoned 'individual,' while a term like 'human
nature,' which is the name of a whole group of attributes, would more
fitly be regarded as collective.

126. The main division of terms, which we have been discussing, into
singular and collective, is based upon their Quantity in
Extension. This phrase will be explained presently.

126. We come now to a threefold division of terms into Positive,
Privative and Negative. It is based upon an implied two-fold division
into positive and non-positive, the latter member being subdivided
into Privative and Negative.
