3. They say what Relation the Mind gives to its own Thoughts.

This part of grammar has been perhaps as much neglected as some others
over-diligently cultivated. It is easy for men to write, one after
another, of cases and genders, moods and tenses, gerunds and supines: in
these and the like there has been great diligence used; and particles
themselves, in some languages, have been, with great show of exactness,
ranked into their several orders. But though PREPOSITIONS and
CONJUNCTIONS, &c., are names well known in grammar, and the particles
contained under them carefully ranked into their distinct subdivisions;
yet he who would show the right use of particles, and what significancy
and force they have, must take a little more pains, enter into his
own thoughts, and observe nicely the several postures of his mind in
discoursing.


4. They are all marks of some action or intimation of the mind.

Neither is it enough, for the explaining of these words, to render them,
as is usual in dictionaries, by words of another tongue which come
nearest to their signification: for what is meant by them is commonly as
hard to be understood in one as another language. They are all marks of
some action or intimation of the mind; and therefore to understand them
rightly, the several views, postures, stands, turns, limitations, and
exceptions, and several other thoughts of the mind, for which we have
either none or very deficient names, are diligently to be studied. Of
these there is a great variety, much exceeding the number of particles
that most languages have to express them by: and therefore it is not
to be wondered that most of these particles have divers and sometimes
almost opposite significations. In the Hebrew tongue there is a particle
