dearer than we buy; or to
give more to a man than he merits. The value of all things contracted
for, is measured by the Appetite of the Contractors: and therefore the
just value, is that which they be contented to give. And Merit (besides
that which is by Covenant, where the performance on one part, meriteth
the performance of the other part, and falls under Justice Commutative,
not Distributive,) is not due by Justice; but is rewarded of Grace
onely. And therefore this distinction, in the sense wherein it useth to
be expounded, is not right. To speak properly, Commutative Justice,
is the Justice of a Contractor; that is, a Performance of Covenant,
in Buying, and Selling; Hiring, and Letting to Hire; Lending, and
Borrowing; Exchanging, Bartering, and other acts of Contract.

And Distributive Justice, the Justice of an Arbitrator; that is to say,
the act of defining what is Just. Wherein, (being trusted by them that
make him Arbitrator,) if he performe his Trust, he is said to distribute
to every man his own: and his is indeed Just Distribution, and may
be called (though improperly) Distributive Justice; but more properly
Equity; which also is a Law of Nature, as shall be shewn in due place.

The Fourth Law Of Nature, Gratitude

As Justice dependeth on Antecedent Covenant; so does Gratitude depend
on Antecedent Grace; that is to say, Antecedent Free-gift: and is the
fourth Law of Nature; which may be conceived in this Forme, "That a man
which receiveth Benefit from another of meer Grace, Endeavour that he
which giveth it, have no reasonable cause to repent him of his good
will." For no man giveth, but with intention of Good to himselfe;
because Gift is Voluntary; and of all Voluntary Acts, the Object is to
every man his own Good; of which if men see they shall be frustrated,
there will be no beginning of benevolence, or trust; nor consequently of
mutuall help; nor of reconciliation of one man to another; and therefore
they are to remain still in the condition of War; which is contrary to
the first and Fundamentall Law of Nature, which commandeth men to Seek
Peace. The breach of this Law, is called Ingratitude; and hath the same
relation to Grace, that Injustice hath to Obligation by Covenant.

The Fifth, Mutuall accommodation, or Compleasance

A fifth Law of Nature, is COMPLEASANCE; that is to say, "That every
man strive to accommodate himselfe to the rest." For the understanding
whereof, we may consider
