7. In the first place, you
yourselves, too,34373437 see
clearly that, if you ever discuss obscure subjects, and seek to lay
bare the mysteries of nature, on the one hand you do not know the very
things 436which you speak
of, which you affirm, which you uphold very often with especial zeal,
and that each one defends with obstinate resistance his own
suppositions as though they were proved and ascertained
truths. For how can we of ourselves know whether
we34383438 perceive
the truth, even if all ages be employed in seeking out
knowledge—we whom some envious power34393439 brought forth, and formed so ignorant
and proud, that, although we know nothing at all, we yet deceive
ourselves, and are uplifted by pride and arrogance so as to suppose
ourselves possessed of knowledge? For, to pass by divine things,
and those plunged in natural obscurity, can any man explain that which
in the Phædrus34403440
the well-known Socrates cannot comprehend—what man is, or whence
he is, uncertain, changeable, deceitful, manifold, of many kinds? for
what purposes he was produced? by whose ingenuity he was devised? what
he does in the world? (C) why he undergoes such countless ills? whether
the earth gave life to him as to worms and mice, being affected with
decay through the action of some moisture;34413441 or whether he received34423442 these outlines of body, and this
cast of face, from the hand of some maker and framer? Can he, I
say, know these things, which lie open to all, and are recognisable
by34433443 the senses
common to all,—by what causes we are plunged into sleep,
by what we awake? in what ways dreams are produced, in what they are
seen? nay rather—as to which Plato in the
Theætetus34443444 is in doubt—whether we are ever
awake, or whether that very state which is called waking is part of an
unbroken slumber? and what we seem to do when we say that we see a
dream? whether we see by means of rays of light proceeding towards the
object,34453445 or images of
the objects fly to and alight on the pupils of our eyes? whether the
flavour is in the things tasted, or arises from their touching
the palate? from what causes hairs lay aside their natural darkness,
and do not become gray all at once, but by adding little by little? why
it is that all fluids, on mingling, form one whole; that oil,
on the contrary, does not suffer the others to be poured into
it,34463446 but is ever
brought together clearly into its own impenetrable34473447 substance? finally, why the soul also,
which is said by you to be immortal and divine,34483448 is sick in men who are sick,
senseless in children, worn out in doting, silly,34493449 and crazy old age? Now the
weakness and wretched ignorance of these theories is greater on
this account, that while it may happen that we at times say something
which is true,34503450 we cannot be
sure even of this very thing, whether we have spoken the truth at
all.
