The things which are seen are opposed in Scripture to the things which
are unseen—they are equally opposed in Plato to universals and ideas.
To him all particulars appear to be floating about in a world of sense;
they have a taint of error or even of evil. There is no difficulty in
seeing that this is an illusion; for there is no more error or
variation in an individual man, horse, bed, etc., than in the class
man, horse, bed, etc.; nor is the truth which is displayed in
individual instances less certain than that which is conveyed through
the medium of ideas. But Plato, who is deeply impressed with the real
importance of universals as instruments of thought, attributes to them
an essential truth which is imaginary and unreal; for universals may be
often false and particulars true. Had he attained to any clear
conception of the individual, which is the synthesis of the universal
and the particular; or had he been able to distinguish between opinion
and sensation, which the ambiguity of the words (Greek) and the like,
tended to confuse, he would not have denied truth to the particulars of
sense.
But the poets are also the representatives of falsehood and feigning in
all departments of life and knowledge, like the sophists and
rhetoricians of the Gorgias and Phaedrus; they are the false priests,
false prophets, lying spirits, enchanters of the world. There is
another count put into the indictment against them by Plato, that they
are the friends of the tyrant, and bask in the sunshine of his
patronage. Despotism in all ages has had an apparatus of false ideas
and false teachers at its service—in the history of Modern Europe as
well as of Greece and Rome. For no government of men depends solely
upon force; without some corruption of literature and morals—some
appeal to the imagination of the masses—some pretence to the favour of
heaven—some element of good giving power to evil, tyranny, even for a
short time, cannot be maintained. The Greek tyrants were not insensible
to the importance of awakening in their cause a Pseudo-Hellenic
feeling; they were proud of successes at the Olympic games; they were
not devoid of the love of literature and art. Plato is thinking in the
first instance of Greek poets who had graced the courts of Dionysius or
Archelaus: and the old spirit of freedom is roused within him at their
prostitution of the Tragic Muse in the praises of tyranny. But his
prophetic eye extends beyond them to the false teachers of other ages
who are the creatures of the government under which they live. He
compares the corruption of his contemporaries with the idea of a
perfect society, and gathers up into one mass of evil the evils and
errors of mankind; to him they are personified in the rhetoricians,
sophists, poets, rulers who deceive and govern the world.
