I'm not sure about the method Socrates says is a "gift from heaven." He often mythologizes ideas, perhaps to give them more weight, or simply to draw attention to them. What I find interesting is that, just as the differentiates between philosophy and sophism, he differentiates between disputation and dialectic. In both distinctions, the difference isn't in method, but in motive.
Soc. The sciences are a numerous class, and will be found
to present great differences. But even admitting that, like the
pleasures,
they are opposite as well as different, should I be
worthy of the name
of
dialectician if, in order to avoid this
difficulty, I were to say (as
you are saying of pleasure) that
there is no difference between one science
and another;-would
not the argument founder and disappear like an idle
tale,
although we might ourselves escape drowning by
clinging to a fallacy?
Soc. A gift of heaven, which, as I conceive, the gods tossed
among men by the hands of a new Prometheus, and therewith a blaze
of light;
and the ancients, who were our betters and nearer the
gods than we are,
handed down the tradition, that whatever
things are said to be are composed
of one and many, and have
the finite, and infinite implanted in them: seeing,
then, that
such is the order of the world, we too ought in every enquiry
to
begin by laying down one idea of that which is the subject of enquiry;
this unity we shall find in everything. Having found it, we may
next proceed
to look for two, if there be two, or, if not, then
for three or some other
number, subdividing each of these
units, until at last the unity with which
we began is seen not
only to be one and many and infinite, but also a definite
number;
the infinite must not be suffered to approach the many until the
entire
number of the species intermediate between unity and infinity has
been
discovered-then, and not till then, we may, rest from division, and
without further troubling ourselves about the endless individuals
may allow
them to drop into infinity. This, as I was saying, is
the way of considering
and learning and teaching one another,
which the gods have handed down
to us. But the wise men of our
time are either too quick or too slow, in
conceiving plurality
in unity. Having no method, they make their one and
many
anyhow, and from unity pass at once to infinity; the intermediate
steps
never occur to them. And this, I repeat, is what makes the difference
between the mere art of
disputation and
true dialectic.
