6. This matter of the use of particles but lightly touched here.
To these, I doubt not, might be added a great many
other significations of this particle, if it were my business to examine it in its full latitude, and consider it in all the
places it is to be found: which if one should do, I doubt whether in all those manners it is made use of, it would
deserve the title of discretive, which grammarians give to it. But I intend not here a full explication of this sort of
signs. The instances I have given in this one may give occasion to reflect on their use and force in language, and
lead us into the contemplation of several actions of our minds in discoursing, which it has found a way to intimate
to others by these particles, some whereof constantly, and others in certain constructions, have the sense of a
whole sentence contained in them.
