ne meaning and one name; for virtue is a habit
of the mind, consistent with nature, and moderation, and reason.
Wherefore, when we have become acquainted with all its divisions, it
will be proper to consider the whole force of simple honesty.

It has then four divisions--prudence, justice, fortitude, and
temperance. Prudence is the knowledge of things which are good, or
bad, or neither good nor bad. Its parts are memory, intelligence,
and foresight. Memory is that faculty by which the mind recovers the
knowledge of things which have been. Intelligence is that by which it
perceives what exists at present. Foresight is that by which anything
is seen to be about to happen, before it does happen. Justice is a
habit of the mind which attributes its proper dignity to everything,
preserving a due regard to the general welfare. Its first principles
proceed from nature. Subsequently some practices became established by
universal custom, from a consideration of their utility; afterwards
the fear of the laws and religion sanctioned proceedings which
originated in nature, and had been approved of by custom.

Natural law is that which has not had its origin in the opinions of
men, but has been implanted by some innate instinct, like religion,
affection, gratitude, revenge, attention to one's superiors, truth.
Religion is that which causes men to pay attention to, and to respect
with fixed ceremonies, a certain superior nature which men call
divine nature. Affection is that feeling under the influence of which
kindness and careful attention is paid to those who are united to us
by ties of blood, or who are devoted to the service of their country.
Gratitude is that feeling in which the recollection of friendship,
and of the services which we have received from another, and the
inclination to requite those services, is contained. Revenge is that
disposition by which violence and injury, and altogether everything
which can be any injury to us, is repelled by defending oneself from
it, or by avenging it. Attention is that feeling by which men obey
when they think those who are eminent for worth or dignity, worthy of
some special respect and honour. Truth is that by which those things
which are, or which have been previously, or which are about to
happen, are spoken of without any alteration.

LIV. Conventional law is a principle which has either derived its
origin in a slight degree from nature, and then has been strengthened
by habit
