ge, or old age as the setting of life. Using a metaphor, he
departs from the words proper to the matter in hand and to his own
art. This is enough as to definition. Let us now consider the other
points.

VIII. But we must employ partition in such a manner as to omit no part
whatever. As if you wish to partition guardianship, you would act
ignorantly if you were to omit any kind. But if you were partitioning
off the different formulas of stipulations or judicial decisions, then
it is not a fault to omit something in a matter which is of boundless
extent. But in division it is a fault; for there is a settled number
of species which are subordinate to each genus. The distribution of
the parts is often more interminable still, like the drawing streams
from a fountain. Therefore in the art of an orator, when the genus
of a question is once laid down, the number of its species is added
absolutely; but when rules are given concerning the embellishments of
words and sentences, which are called [Greek: _schaemata_], the case
is different; for the circumstances are more infinite: so that it may
be understood from this also what the difference is which we assert to
exist between partition and division. For although the words appear
nearly equivalent to one another still, because the things are
different, the expressions are also established as not synonymous to
one another.

Many arguments are also derived from observation, and that is when
they are deduced from the meaning of a word, which the Greeks call
[Greek: _etumologia_]; or as we might translate it, word for word,
_veriloquium_. But we, while avoiding the novel appearance of a word
which is not very suitable, call this kind of argument _notatio_,
because words are the notes by which we distinguish things. And
therefore Aristotle calls the same source of argument [Greek:
_sunbolou_], which is equivalent to the Latin _nota_. But when it is
known what is meant we need not be so particular about the name. In
a discussion then, many arguments are derived from words by means
of observation; as when the question is asked, what is a
_postliminium_--(I do not mean what are the objects to which this word
applies, for that would be division, which is something of this sort:
"_Postliminium_ applies to a man, a ship, a mule with panniers, a
horse, a mare who is accustomed to be bridled")--but when the meaning
of the word itself, _postliminium_, is asked, and when the word itself
is
