uths; I have therefore taken them all from
the very natures of the subject of which I am treating _viz_: from the
deflections and different regards under which the consideration of words
may be manag'd; wch may last of all serve for an assurance, that chance
hath not all that Empire and authority, that is given it over the
Languages; and that it would be no great difficulty to make it appear, that
in the Languages themselves there are well fram'd and solid reasons, for
every thing that appears otherwise, and hath been hitherto suppos'd to be
the bare effect of Caprice.

It may be perceiv'd by the very effects themselves that it will make up a
science fully demonstrative, and back't with such consequences, as may very
well passe for compleat models in this kind: And above all the scope of its
principles infinitely shortens the way without being at all oblig'd to make
a descent to a thousand taedious and wearisome differences; which appear
much better, and in a more elegant manner in their principles then in
themselves, which is an incouragement for me to hope that a Language for
the acquest of which we have formerly by a close application numbred
severall years, will by this means be made the divertisement of some hours,
or at most but some few days.

Words being in the opinion of all men but significant sounds, they may be
taken either as they are _Natural sounds_, or _arbitrary signs_, I would
say, either as they are the proper effect of the motion of our organs, or
as the lively representation of the thought of our minds. And since they
make their passes from one Language to another they cannot well admit of
any alteration in this their transit but in three respects; for whatsoever
change be suppos'd it will necessarily fall out, either in the _sounds
themselves_ that compose the words, or in _their significations_, or in
their _different modifications_, and its from these three distinct regards
that the generall principles have their rise, upon which I have fastn'd
this new Systime of the Philosophie of the Languages.

That I may make my procedure more justificable and artificiall, I examine
with all exactnesse the different organs of the voice, the various motions
of the muscles belonging to these organs, and the admirable concent and
accord of those motions; and these I make use of to demonstratively
explaine the precise number of all the simple sounds, that enter into the
composition of the Languages, to discover
