nctioned by
law, that every man has a right to the property of another, the gift
would have no merit--charity and gratitude would be no longer virtues.
Besides, such a doctrine would suddenly and universally arrest labour
and production, as severe cold congeals water and suspends animation;
for who would work if there was no longer to be any connection between
labour and the satisfying of our wants? Political economy has not
treated of gifts. It has hence been concluded that it disowns them, and
that it is therefore a science devoid of heart. This is a ridiculous
accusation. That science which treats of the laws resulting from the
_reciprocity of services_, had no business to inquire into the
consequences of generosity with respect to him who receives, nor into
its effects, perhaps still more precious, on him who gives: such
considerations belong evidently to the science of morals. We must allow
the sciences to have limits; above all, we must not accuse them of
denying or undervaluing what they look upon as foreign to their
department.

The right of inheritance, against which so much has been objected of
late, is one of the forms of gift, and assuredly the most natural of
all. That which a man has produced, he may consume, exchange, or give.
What can be more natural than that he should give it to his children? It
is this power, more than any other, which inspires him with courage to
labour and to save. Do you know why the principle of right of
inheritance is thus called in question? Because it is imagined that the
property thus transmitted is plundered from the masses. This is a fatal
error. Political economy demonstrates, in the most peremptory manner,
that all value produced is a creation which does no harm to any person
whatever. For that reason it may be consumed, and, still more,
transmitted, without hurting any one; but I shall not pursue these
reflections, which do not belong to the subject.

Exchange is the principal department of political economy, because it is
by far the most frequent method of transmitting property, according to
the free and voluntary agreements of the laws and effects of which this
science treats.

Properly speaking, exchange is the reciprocity of services. The parties
say between themselves, "Give me this, and I will give you that;" or,
"Do this for me, and I will do that for you." It is well to remark (for
this will throw a new light on the notion of value) that the second
form is alw
