as the mother of all of them. And this is nearly what he
laid down about morals.

XI. But about natures he held these opinions. In the first place, he did
not connect this fifth nature, out of which his predecessors thought that
sense and intellect were produced, with those four principles of things.
For he laid it down that fire is that nature which produces everything,
and intellect, and sense. But he differed from them again, inasmuch as he
thought it absolutely impossible for anything to be produced from that
nature which was destitute of body; which was the character attributed by
Xenocrates and his predecessors to the mind, and he would not allow that
that which produced anything, or which was produced by anything, could
possibly be anything except body.

But he made a great many alterations in that third part of his philosophy,
in which, first of all, he said some new things of the senses themselves:
which he considered to be united by some impulse as it were, acting upon
them from without, which he called {~GREEK SMALL LETTER PHI~}{~GREEK SMALL LETTER ALPHA~}{~GREEK SMALL LETTER NU~}{~GREEK SMALL LETTER TAU~}{~GREEK SMALL LETTER ALPHA~}{~GREEK SMALL LETTER SIGMA~}{~GREEK SMALL LETTER IOTA WITH OXIA~}{~GREEK SMALL LETTER ALPHA~}, and which we may term
_perception_. And let us recollect this word, for we shall have frequent
occasion to employ it in the remainder of our discourse; but to these
things which are perceived, and as it were accepted by the senses, he adds
the assent of the mind, which he considers to be placed in ourselves and
voluntary. He did not give credit to everything which is perceived, but
only to those which contain some especial character of those things which
are seen; but he pronounced what was seen, when it was discerned on
account of its own power, _comprehensible_--will you allow me this word?
Certainly, said Atticus, for how else are you to express {~GREEK SMALL LETTER KAPPA~}{~GREEK SMALL LETTER ALPHA~}{~GREEK SMALL LETTER TAU~}{~GREEK SMALL LETTER ALPHA~}{~GREEK SMALL LETTER LAMDA~}{~GREEK SMALL LETTER ETA~}{~GREEK SMALL LETTER PI~}{~GREEK SMALL LETTER TAU~}{~GREEK SMALL LETTER OMICRON WITH OXIA~}{~GREEK SMALL LETTER FINAL SIGMA~}? But
after it had been received and approved, then he called it
_comprehension_, resembling those things which are taken up
(_prehenduntur_) in the hand; from which verb also he derived this noun,
though no one else had ever used this verb with reference to such mat
