As to Quantity, propositions are either Universal or Particular; that is
to say, the predicate is affirmed or denied either of the whole subject
or of a part of it--of _All_ or of _Some S_.

_All S is P_ (that is, _P_ is predicated of _all S_).
_Some S is P_ (that is, _P_ is predicated of _some S_).

An Universal Proposition may have for its subject a singular term, a
collective, a general term distributed, or an abstract term.

(1) A proposition having a singular term for its subject, as _The Queen
has gone to France_, is called a Singular Proposition; and some
Logicians regard this as a third species of proposition with respect to
quantity, distinct from the Universal and Particular; but that is
needless.

(2) A collective term may be the subject, as _The Black Watch is ordered
to India_. In this case, as well as in singular propositions, a
predication is made concerning the whole subject as a whole.

(3) The subject may be a general term taken in its full denotation, as
_All apes are sagacious_; and in this case a Predication is made
concerning the whole subject distributively; that is, of each and
everything the subject stands for.

(4) Propositions whose subjects are abstract terms, though they may
seem to be formally Singular, are really as to their meaning
distributive Universals; since whatever is true of a quality is true of
whatever thing has that quality so far as that quality is concerned.
