ttance except on business": "Only Protestants can
sit on the throne of England".
These propositions exemplify different ways in common speech of naming
a subject _exclusively_, the predication being made of all outside a
certain term. "None that are not brave, etc.;" "none that are not on
business, etc.;" "none that are not Protestants, etc.". No not-S is
P. It is only about all outside the given term that the universal
assertion is made: we say nothing universally about the individuals
within the term: we do not say that all Protestants are eligible, nor
that all persons on business are admitted, nor that every one of the
brave deserves the fair. All that we say is that the possession of the
attribute named is an indispensable condition: a person may possess
the attribute, and yet on other grounds may not be entitled to the
predicate.
The justification for taking special note of this form in Logic is
that we are apt by inadvertence to make an inclusive inference from
it. Let it be said that None but those who work hard can reasonably
expect to pass, and we are apt to take this as meaning that all who
work hard may reasonably expect to pass. But what is denied of every
Not-S is not necessarily affirmed of every S.
_The expression of_ TENSE or TIME _in the Syllogistic Forms_. Seeing
that the Copula in S is P or S is in P does not express time, but only
a certain relation between S and P, the question arises Where are we
to put time in the analytic formula? "Wheat is dear;" "All had fled;"
time is expressed in these propositions, and our formula should
render the whole content of what is given. Are we to include it in
the Predicate term or in the Subject term? If it must not be left out
altogether, and we cannot put it with the copula, we have a choice
between the two terms.
It is a purely scholastic question. The common technical treatment is
to view the tense as part of the predicate. "All had fled," All S is
P, _i.e._, the whole subject is included in a class constituted on the
attributes of flight at a given time. It may be that the Predicate is
solely a predicate of time. "The Board met yesterday at noon." S is P,
_i.e._, the meeting of the Board is one of the events characterised by
having happened at a certain time, agreeing with other events in that
respect.
But in some cases the time is more properly regarded as part of the
subject. _E.g._, "Wheat is dear". S does not here stand for wheat
collectively
