approach our climate, render our atmosphere dense, and thus operating on
the temperament, may influence the passions of a man, whose
circumstances shall have capacitated him to influence many others, who
shall decide after his will the fate of many nations.

Man, in fact, finds himself in Nature, and makes a part of it: he acts
according to laws, which are appropriate to him; he receives in a manner
more or less distinct, the action and impulse of the beings who surround
him; who themselves act after laws that are peculiar to their essence.
Thus he is variously modified; but his actions are always the result of
his own energy, and that of the beings who act upon him, and by whom he
is modified. This is what gives such variety to his determinations--what
generally produces such contradiction in his thoughts, his opinions, his
will, his actions; in short, in that motion, whether concealed or
visible, by which he is agitated. We shall have occasion, in the sequel,
to place this truth, at present so much contested, in a clearer light:
it will be sufficient for our purpose at present to prove, generally,
that every thing in Nature is necessary--that nothing to be found in it
can act otherwise than it does.

Motion, alternately communicated and received, establishes the
connection or relation between the different orders of beings: when they
are in the sphere of reciprocal action, attraction approximates them;
repulsion dissolves and separates them; the one strengthens and
preserves them; the other enfeebles and destroys them. Once combined,
they have a tendency to conserve themselves in that mode of existence,
by virtue of their _inert force_; in this they cannot succeed, because
they are exposed to the continual influence of all other beings, who
perpetually and successively act upon them; their change of form, their
dissolution, is requisite to the preservation of Nature herself: this is
