most enlightened, regarded this idea as if it were infused into him by
Nature; whilst it is visibly to be attributed to those delineations of
it, which his parents or his instructors have made to him; which he has,
in consequence, modified according to his own particular organization,
and the circumstances in which he has been placed; it is thus, that each
individual forms to himself a God, of which he is himself the model, or
which he modifies after his own fashion.

His ideas of morals, although more real than those of metaphysics, are
not however innate: the moral sentiments he forms on the will, or the
judgment he passes on the actions of man, are founded on experience;
which alone can enable him to discriminate those which are either useful
or prejudicial, virtuous or vicious, honest or dishonest, worthy his
esteem, or deserving his censure. His moral sentiments are the fruit of
a multitude of experience that is frequently very long and very
complicated. He gathers it with time; it is more or less faithful, by
reason of his particular organization and the causes by which he is
modified; he ultimately applies this experience with greater or less
facility; to this is to be attributed his habit of judging. The celerity
with which he applies his experience when he judges of the moral actions
of his fellow man, is what has been termed _moral instinct_.

That which in natural philosophy is called _instinct_, is only the
effect of some want of the body, the consequence of some attraction or
some repulsion in man or animals. The child that is newly born, sucks
for the first time; the nipple of the breast is put into his mouth: by
the natural analogy, that is found between the conglomerate glands,
filled with nerves; which line his mouth, and the milk which flows from
the bosom of the nurse, through the medium of the nipple, causes the
child to press it with his mouth, in order to express the fluid
