e of sexes, ages, governments, conditions,
or methods of education; the same uniformity and regular operation
of natural principles are discernible. Uke causes still produce like
effects; in the same manner as in the mutual action of the elements and
powers of nature.

There are different trees, which regularly produce fruit, whose relish
is different from each other; and this regularity will be admitted as
an instance of necessity and causes in external bodies. But are the
products of Guienne and of Champagne more regularly different than the
sentiments, actions, and passions of the two sexes, of which the one are
distinguished by their force and maturity, the other by their delicacy
and softness?

Are the changes of our body from infancy to old age more regular and
certain than those of our mind and conduct? And would a man be more
ridiculous, who would expect that an infant of four years old will raise
a weight of three hundred pound, than one, who from a person of the
same age would look for a philosophical reasoning, or a prudent and
well-concerted action?

We must certainly allow, that the cohesion of the parts of matter arises
from natural and necessary principles, whatever difficulty we may find
in explaining them: And for a reason we must allow, that human society
is founded on like principles; and our reason in the latter case, is
better than even that in the former; because we not only observe, that
men always seek society, but can also explain the principles, on which
this universal propensity is founded. For is it more certain, that two
flat pieces of marble will unite together, than that two young savages
of different sexes will copulate? Do the children arise from this
copulation more uniformly, than does the parents care for their safety
and preservation? And after they have arrived at years of discretion
by the care of their parents, are the inconveniencies attending their
separation more certain than their foresight of these inconveniencies
and their care of avoiding them by a close union and confederacy?

The skin, pores, muscles, and nerves of a day-labourer are different
from those of a man of quality: So are his sentiments, actions and
manners. The different stations of life influence the whole fabric,
external and internal; and different stations arise necessarily, because
uniformly, from the necessary and uniform principles of human nature.
Men cannot live without society, and cannot be assoc
