nchise." This, perhaps,
may do. For I am not aware that Scaevola, the pontiff, added anything
to this definition. And this principle holds good in each kind of
definition, whether the thing to be defined is something which exists,
or something which is understood.

VII. But we have shown now what is meant by partition, and by
division. But it is necessary to explain more clearly wherein
they differ. In partition, there are as it were members; as of a
body--head, shoulders, hands, sides, legs, feet, and so on. In
division there are forms which the Greeks call [Greek: ideae]; our
countrymen who treat of such subjects call them species. And it is not
a bad name, though it is an inconvenient one if we want to use it in
different cases. For even if it were Latin to use such words, I
should not like to say _specierum_ and _speciebus_. And we have often
occasion to use these cases. But I have no such objection to saying
_formarum_ and _formis_; and as the meaning of each word is the same,
I do not think that convenience of sound is wholly to be neglected.

Men define genus and species or form in this manner:--"Genus is
a notion relating to many differences. Species is a notion, the
difference of which can be referred to the head and as it were
fountain of the genus." I mean by notion that which the Greeks call
sometimes [Greek: _ennoia_], and sometimes [Greek: _enoprolaepsis_].
It is knowledge implanted and previously acquired of each separate
thing, but one which requires development. Species, then, are those
forms into which genus is divided without any single one being
omitted; as if any one were to divide justice into law, custom, and
equity. A person who thinks that species are the same things as parts,
is confounding the art; and being perplexed by some resemblance,
he does not distinguish with sufficient acuteness what ought to be
distinguished. Often, also, both orators and poets define by metaphor,
relying on some verbal resemblance, and indeed not without giving a
certain degree of pleasure. But I will not depart from your examples
unless I am actually compelled to do so.

Aquillius, then, my colleague and intimate friend, was accustomed,
when there was any discussion about shores, (all of which you lawyers
insist upon it are public,) to define them to men who asked to whom
that which was shore belonged, in this way: "Wherever the waves
dashed;" that is, as if a man were to define youth as the flower of
a man's a
