But where the resemblances and differences on which our classifications
are founded are not of this palpable and easily determinable kind;
especially where they consist not in any one quality but in a number of
qualities, the effects of which being blended together are not very
easily discriminated, and referred each to its true source; it often
happens that names are applied to nameable objects, with no distinct
connotation present to the minds of those who apply them. They are only
influenced by a general resemblance between the new object and all or
some of the old familiar objects which they have been accustomed to call
by that name. This, as we have seen, is the law which even the mind of
the philosopher must follow, in giving names to the simple elementary
feelings of our nature: but, where the things to be named are complex
wholes, a philosopher is not content with noticing a general
resemblance; he examines what the resemblance consists in: and he only
gives the same name to things which resemble one another in the same
definite particulars. The philosopher, therefore, habitually employs his
general names with a definite connotation. But language was not made,
and can only in some small degree be mended, by philosophers. In the
minds of the real arbiters of language, general names, especially where
the classes they denote cannot be brought before the tribunal of the
outward senses to be identified and discriminated, connote little more
than a vague gross resemblance to the things which they were earliest,
or have been most, accustomed to call by those names. When, for
instance, ordinary persons predicate the words _just_ or _unjust_ of any
action, _noble_ or _mean_ of any sentiment, expression, or demeanour,
_statesman_ or _charlatan_ of any personage figuring in politics, do
they mean to affirm of those various subjects any determinate
attributes, of whatever kind? No: they merely recognise, as they think,
some likeness, more or less vague and loose, between these and some
other things which they have been accustomed to denominate or to hear
denominated by those appellations.
