animals, men; organized, sensible and thinking beings, as well as those destitute of feeling
and of thought. All these beings act only for the term of their respective duration, according
to invariable laws, determined by their properties, by their configuration, their masses, their
weight, &c. Here is the true origin of every thing which presents itself to our view, showing
the mode in which nature, by its own peculiar power, is in a state to produce all those effects,
of which our eyes witness, as well as all the bodies which act diversely upon the organs
which we are furnished, and of which, we judge only according to the manner in which these
organs are affected. We say they are good, when they are congenial to us, or contribute to
maintain harmony in ourselves; we say they are bad, when they disturb this harmony; and
we ascribe, in consequence, an aim, ideas, designs, to the being, whom we make the motive-
power of a nature which we see destitute of projects and intelligence.
Nature is effectually destitute of them; she has no intelligence or end; she acts necessarily,
because she exists necessarily. Her laws are immutable and founded upon the essence of
things. It is the essence of the seed of the male, composed of the primitive elements, which
serve for the basis of an organized being, to unite itself with that of the female, to fructify it,
to produce, by its combination with it, a new organized being, who, feeble in his origin, for
want of a sufficient quantity of particles of matter, suitable to give him consistence,
strengthens himself by degrees, by the daily and continual addition of particles, analogous
and appropriate to his being; thus he lives, he thinks, he is nourished, and he engenders, in
his turn, organized beings similar to himself. By a consequence of permanent and physical
laws, generation does not take place, except when the circumstances necessary to produce
it find themselves united. Thus, this procreation is not operated by chance; the animal does
not produce but with an animal of his own species, because this is the only one analogous
to himself, or who unites the qualities suitable to the producing a being similar to himself;
without this, he would not produce any thing, he would only produce a being, denominated
monstrous,
because it would be dissimilar to himself. It is of the essence of the grain of
plants, to be fructified by the seed of the stamina of the flower, to develop themselves in
consequence in the bowels of the earth, to grow with the assistance of water, to attract for
that purpose analogous particles, to form by degrees a plant, a shrub, a tree susceptible of the
life, the action, the motion, suitable to vegetables. It is of the essence of particles of earth,
attenuated, divided, elaborated by water and by heat, to unite themselves, in the bosom of
mountains, with those which are analogous to them, and to form by their aggregation,
according as they are more or less similar or analogous, bodies, more or less solid and pure,
which we denominate crystals, stones, metals, minerals. It is the essence of the exhalations,
raised by the heat of the atmosphere, to combine, to collect themselves, to dash against each
other, and, by their combination or their collision, to produce meteors and thunder. It is the
essence of some inflammable matter to collect itself, to ferment, to heat itself in the caverns
of the earth, to produce those terrible explosions and those earthquakes which destroy
mountains, plains, and the habitations of alarmed nations; these complain to an unknown
being, of the evils which nature makes them experience as necessarily as those benefits
which fill them with joy. In short, it is the essence of certain climates, to produce men so
