Having already sufficiently considered
the general principles of this subject, let us now
go into the practical part thereof; the one is a liberal
employment for the mind, the other necessary.
These things are useful in the management of one’s
affairs; to be skilful in the nature of cattle, which
are most profitable, and where, and how; as for instance,
what advantage will arise from keeping horses, or oxen,
or sheep, or any other live stock; it is also necessary
to be acquainted with the comparative value of these
things, and which of them in particular places are
worth most; for some do better in one place, some
in another. Agriculture also should be understood,
and the management of arable grounds and orchards;
and also the care of bees, and fish, and birds, from
whence any profit may arise; these are the first and
most proper parts of domestic management.
With respect to gaining money by exchange,
the principal method of doing this is by merchandise,
which is carried on in three different ways, either
by sending the commodity for sale by sea or by land,
or else selling it on the place where it grows; and
these differ from each other in this, that the one
is more profitable, the other safer. The second
method is by usury. The third by receiving wages
for work done, and this either by being employed in
some mean art, or else in mere bodily labour.
There is also a third species of improving a fortune,
that is something between this and the first; for it
partly depends upon nature, partly upon exchange;
the subject of which is, things that are immediately
from the earth, or their produce, which, though they
bear no fruit, are yet useful, such as selling of timber
and the whole art of metallurgy, which includes many
different species, for there are various sorts of
things dug out of the earth.
These we have now mentioned in general,
but to enter into particulars concerning each of them,
though it might be useful to the artist, would be
tiresome to dwell on. Now of all the works of
art, those are the most excellent wherein chance has
the least to do, and those are the meanest which deprave
the body, those the most servile in which bodily strength
alone is chiefly wanted, those most illiberal which
require least skill; but as there are books written
on these subjects by some persons, as by Chares the
Panian, and Apollodorus the Lemnian, upon husbandry
and planting; and by others on other matters, [1259b]
let those who have occasion consult them thereon; besides,
every person should collect together whatsoever he
hears occasionally mentioned, by means of which many
of those who aimed at making a fortune have succeeded
in their intentions; for all these are useful to those
who make a point of getting money, as in the contrivance
of Thales the Milesian (which was certainly a gainful
one, but as it was his it was attributed to his wisdom,
though the method he used was a general one, and would
universally succeed), when they reviled him for his
poverty, as if the study of philosophy was useless:
for they say that he, perceiving by his skill in astrology
that there would be great plenty of olives that year,
while it was yet winter, having got a little money,
he gave earnest for all the oil works that were in
Miletus and Chios, which he hired at a low price, there
being no one to bid against him; but when the season
came for making oil, many persons wanting them, he
all at once let them upon what terms he pleased; and
raising a large sum of money by that means, convinced
them that it was easy for philosophers to be rich if
they chose it, but that that was not what they aimed
at; in this manner is Thales said to have shown his
wisdom. It indeed is, as we have said, generally
gainful for a person to contrive to make a monopoly
of anything; for which reason some cities also take
this method when they want money, and monopolise their
commodities. There was a certain person in Sicily
who laid out a sum of money which was deposited in
his hand in buying up all the iron from the iron merchants;
so that when the dealers came from the markets to
purchase, there was no one had any to sell but himself;
and though he put no great advance upon it, yet by
laying out fifty talents he made an hundred. When
Dionysius heard this he permitted him to take his
money with him, but forbid him to continue any longer
in Sicily, as being one who contrived means for getting
money inconsistent with his affairs. This man’s
view and Thales’s was exactly the same; both
of them contrived to procure a monopoly for themselves:
it is useful also for politicians to understand these
things, for many states want to raise money and by
such means, as well as private families, nay more so;
for which reason some persons who are employed in
the management of public affairs confine themselves
to this province only.
