[181] Such, in its full scope, is the journey or pilgrimage, the method
(hodos, kinêsis, methodos)+ of the Socratic, of the perfected Platonic
dialectic, towards the truth, the true knowledge, of Bravery or
Friendship, for instance; of Space or Motion, again, as suggested in
the seventh book of The Republic; of the ideal City, of the immaculate
Beauty. You are going about Justice, for example--that great complex
elevation on the level surface of life, whose top, it may be, reaches
to heaven. You fancy you have grasped its outline. Alla metathômetha.+
You are forced on, perhaps by your companion, a step further, and the
view has already changed. "Persevere," Plato might say, "and a step
may be made, upon which, again, the whole world around may change, the
entire horizon and its relation to the point you stand on--a change
from the half-light of conjecture to the full light of indefectible
certitude." That, of course, can only happen by a summary act of
intuition upon the entire perspective, wherein all those partial
apprehensions, which one by one may have seemed inconsistent with each
other, find their due place, or (to return to the Platonic Dialogue
again, to the actual process of dialectic as there exposed) by that
final impression of a subject, a theorem, in which the mind attains a
hold, as if by a single imaginative act, through all the transitions of
a long conversation, upon all the seemingly opposite contentions of all
the various speakers at once. We see already why [182] Platonic
dialectic--the ladder, as Plato thinks, by which alone we can ascend
into the entirely reasonable world (noêtos topos)+ beginning with the
boyish difficulties and crudities of Meno, for instance, is a process
which may go on, at least with those gifted by nature and opportunity,
as in the Perfect City,--may go on to the close of life, and, as
Pythagorean theory suggests, perhaps does not end even then.
