29. Fourthly, when words are diverted from their common use.
Fourthly, He that applies the words of any language to ideas
different from those to which the common use of that country applies them, however his own understanding may
be filled with truth and light, will not by such words be able to convey much of it to others, without defining his
terms. For however the sounds are such as are familiarly known, and easily enter the ears of those who are
accustomed to them; yet standing for other ideas than those they usually are annexed to, and are wont to excite in
the mind of the hearers, they cannot make known the thoughts of him who thus uses them.
