We have followed him during his forty or fifty years of authorship, from
the beginning when he first attempted to depict the teaching of Socrates
in a dramatic form, down to the time at which the character of Socrates
had disappeared, and we have the latest reflections of Plato's own mind
upon Hellas and upon philosophy. He, who was 'the last of the poets,' in
his book of Laws writes prose only; he has himself partly fallen
under the rhetorical influences which in his earlier dialogues he was
combating. The progress of his writings is also the history of his life;
we have no other authentic life of him. They are the true self of the
philosopher, stripped of the accidents of time and place. The great
effort which he makes is, first, to realize abstractions, secondly,
to connect them. In the attempt to realize them, he was carried into a
transcendental region in which he isolated them from experience, and we
pass out of the range of science into poetry or fiction. The fancies of
mythology for a time cast a veil over the gulf which divides phenomena
from onta (Meno, Phaedrus, Symposium, Phaedo). In his return to earth
Plato meets with a difficulty which has long ceased to be a difficulty
to us. He cannot understand how these obstinate, unmanageable ideas,
residing alone in their heaven of abstraction, can be either combined
with one another, or adapted to phenomena (Parmenides, Philebus,
Sophist). That which is the most familiar process of our own minds, to
him appeared to be the crowning achievement of the dialectical art. The
difficulty which in his own generation threatened to be the destruction
of philosophy, he has rendered unmeaning and ridiculous. For by his
conquests in the world of mind our thoughts are widened, and he has
furnished us with new dialectical instruments which are of greater
compass and power. We have endeavoured to see him as he truly was, a
great original genius struggling with unequal conditions of knowledge,
not prepared with a system nor evolving in a series of dialogues ideas
which he had long conceived, but contradictory, enquiring as he goes
along, following the argument, first from one point of view and then
from another, and therefore arriving at opposite conclusions, hovering
around the light, and sometimes dazzled with excess of light, but always
moving in the same element of ideal truth. We have seen him also in his
decline, when the wings of his imagination have begun to droop, but his
experience of life remains, and he turns away from the contemplation of
the eternal to take a last sad look at human affairs.
