All these terms admit of a medium. In the case of hot or cold, for
example, a substance need not necessarily be either. It may be warm or
cool.
Terms seem to be contradictory when it is a matter of quality, but
opposite when it is a question of quantity or degree.
=11. PRIVATIVE AND NEGO-POSITIVE TERMS.=
_A privative term is one which is positive in form but negative in
meaning._ Such words as blind, deaf, dumb, dead, maimed, orphaned, are
privative terms, in that there is no negative prefix or suffix and yet
they denote the absence of certain qualities. “Blind,” for example, is
positive in form, but denotes absence of sight.
_A nego-positive term is one which is negative in form but positive
in meaning._ Such terms as invaluable, unloosed, immoral, indwell, are
nego-positive because, though they have negative prefixes, yet they
possess a certain positive meaning. “Invaluable,” for instance, does
not mean not-valuable, but very valuable.
=12. ABSOLUTE AND RELATIVE TERMS.=
_An absolute term is one whose meaning becomes intelligible without
reference to other terms._ Automobile, water, tree, house, book, are
absolute terms. Any of them may be made clear to a child or a foreigner
without special reference to other terms. For example, the child will
recognize from certain common marks the automobile every time he sees
it. The marks of tree, house, flower, are apparent to every one.
_A relative term is one which derives its meaning from its relation
to some other term._ Parent, teacher, shepherd, monarch, eldest, cause,
commander, are relative terms. For example, in explaining the meaning
of “_parent_” to a foreigner, reference must be made to “_child_.”
The pairs of terms thus associated are spoken of as correlatives.
Parent and child, teacher and pupil, shepherd and flock, monarch and
subject, eldest and youngest, cause and effect, commander and army,
are correlative terms. Either one of each pair is the correlate to the
other, and every relative term needs its correlate to make its meaning
clear. To say that a relative term denotes an object which cannot be
thought of without reference to some other object, is confusing, as it
is quite impossible to think of any object without calling to mind some
other object or notion. Fire calls to mind water; tree suggests shade,
etc.
