9. Second remedy: To have distinct, determinate ideas annexed to words, especially in mixed modes.
Secondly, It
is not enough a man uses his words as signs of some ideas: those he annexes them to, if they be simple, must be
clear and distinct; if complex, must be determinate, i.e., the precise collection of simple ideas settled in the mind,
with that sound annexed to it, as the sign of that precise determined collection, and no other. This is very
necessary in names of modes, and especially moral words; which, having no settled objects in nature, from
whence their ideas are taken, as from their original, are apt to be very confused. Justice is a word in every man's
mouth, but most commonly with a very undertermined, loose signification; which will always be so, unless a man
has in his mind a distinct comprehension of the component parts that complex idea consists of: and if it be
decompounded, must be able to resolve it still on, till he at last comes to the simple ideas that make it up: and
unless this be done, a man makes an ill use of the word, let it be justice, for example, or any other. I do not say, a
man needs stand to recollect, and make this analysis at large, every time the word justice comes in his way: but
this at least is necessary, that he have so examined the signification of that name, and settled the idea of all its
parts in his mind, that he can do it when he pleases. If any one who makes his complex idea of justice to be, such
a treatment of the person or goods of another as is according to law, hath not a clear and distinct idea what law is,
which makes a part of his complex idea of justice, it is plain his idea of justice itself will be confused and
imperfect. This exactness will, perhaps, be judged very troublesome; and therefore most men will think they may
be excused from settling the complex ideas of mixed modes so precisely in their minds. But yet I must say, till
this be done, it must not be wondered, that they have a great deal of obscurity and confusion in their own minds,
and a great deal of wrangling in their discourse with others.
