communicating its thoughts to others, does not only need signs of the
ideas it has then before it, but others also, to show or intimate some
particular action of its own, at that time, relating to those ideas.
This it does several ways; as _I_S and _I_S NOT, are the general marks,
of the mind, affirming or denying. But besides affirmation or negation,
without which there is in words no truth or falsehood, the mind does,
in declaring its sentiments to others, connect not only the parts of
propositions, but whole sentences one to another, with their several
relations and dependencies, to make a coherent discourse.


2. In right use of Particles consists the Art of Well-speaking

The words whereby it signifies what connexion it gives to the several
affirmations and negations, that it unites in one continued reasoning or
narration, are generally called PARTICLES: and it is in the right use of
these that more particularly consists the clearness and beauty of a good
style. To think well, it is not enough that a man has ideas clear
and distinct in his thoughts, nor that he observes the agreement or
disagreement of some of them; but he must think in train, and observe
the dependence of his thoughts and reasonings upon one another. And to
express well such methodical and rational thoughts, he must have words
to show what connexion, restriction, distinction, opposition, emphasis,
&c., he gives to each respective part of his discourse. To mistake
in any of these, is to puzzle instead of informing his hearer: and
therefore it is, that those words which are not truly by themselves
the names of any ideas are of such constant and indispensable use in
language, and do much contribute to men's well expressing themselves.
