The
Philosophy of Plato
X.
Religion
In the Republic, Plato compares the Idea
of the Good to the sun, as the supreme cause of all
knowledge and existence. As the multiplicity of
individuals is unified in the respective Ideas, in
the same manner the multiplicity of Ideas is
unified in the Idea of the Good. Hence in the
Platonic system the Idea of the Good is the supreme
reality on which all other ideas and all ethical,
logical and aesthetic values of the sensible world
depend. The Idea of the Good is the reality through
which the world of becoming is made possible and
rational. Thus it is truly the god of
Plato.
But the Idea of the Good has neither personality
nor the power of creating. According to Plato,
Demiurge is the divine artificer which forms the
heavens and the earth by successive infusions of
souls. Demiurge, however, cannot be identified with
God, for if he is superior to matter, he is
inferior to ideas, which furnish the model he uses
to arrange matter and transform Chaos in the
visible world.
Since God is identified with the impersonal Idea
of the Good, which lacks any activity with
reference to nature and man. He can be attained
only by reason, and the cult of reason is due
Him.
Regarding popular religion, Plato is opposed to
anthropomorphism. So greatly is he opposed to it
that, as we have seen, he wished to banish the
poets, not excepting Homer, from the ideal state on
account of the fantastic and immoral myths with
which they represent the gods. He is not opposed,
however, to a form of astral polytheism in which a
multitude of gods subject to Demiurge animates the
stars and the cosmic universe. These are the
visible gods which Plato wishes to substitute for
rough and uncouth Grecian mythology.

Insufficiencies of Plato's System
The problem which most troubled the mind of
Plato was that which had already been posed by the
Pre-Socratics: the being of Parmenides and
the becoming of Heraclitus. Plato attempted
a reconciliation of these by introducing the world
of Ideas, which should have given a rational
explanation of both systems of thought.
The being of Parmenides would be the
ideal world, intelligible, the supreme Good. But
differing from Parmenides, who held this
being to be one, solid, and massive, Plato
breaks it up, we might say, into the multiplicity
of Ideas, whose unity lies in their relation
to the supreme Good.
Now along with this logico-metaphysical being,
Plato advances another, non-being, which is
co-eternal with Ideas. This is a metaphysical
dualism such as is found in all Greek philosophers
in the absence of a concept of creation. According
to Plato, Demiurge should be the artificer which is
able to find the answer to Heraclitus' problem of
becoming. Plato places Demiurge before
matter (non-being, opposing the intelligible, the
necessary), in order that the descent of Ideas
might be effected. The intelligible, through the
operation of Demiurge, is imposed upon
non-being. However, the non-being,
the origin of evil, is never completely overcome by
the intelligible. The metaphysics of Plato is
essentially dualistic: the good (Ideas), and the
evil (non-being). Plato unsuccessfully attempts to
explain the becoming of Heraclitus by a
penetration of the irrational by the rational, of
matter by the intelligible.
From this dualism it follows that evil is a
metaphysical and insuppressible necessity. Cosmic
reality is a struggle between good and evil,
between Demiurge and non-being. In the face of the
impenetrability of non-being, Demiurge must be
declared impotent.
Certainly no one has felt more than Plato the
religious significance of the world and of
life. However, a false notion of non-being,
uncreated and co-eternal, the origin of evil, has
impeded the philosopher from attaining a completely
rational and religious vision of man and of nature.
Plotinus was to attempt to overcome this
difficulty, which would finally be answered in St.
Augustine.
XII.
The Academy
The Academy, the philosophic school founded by
Plato, lasted about a thousand years after him --
until the sixth century after Christ. It is usually
divided into three periods:
- The Ancient Academy occupies the
century immediately after the death of the
master. It numbered among its members men of
outstanding influence and doctrine, such as
Speusippus and Arcesilaus.
- The Middle Academy is predominantly
Skeptic. Carneades (214-129 B.C.E.) is the
predominant representative of this tendency. He
denied the possibility, in the speculative
field, of attainting truth; and in the practical
order he defended the sufficiency of
probabilism.
- The New Academy, which endured until
the beginning of the era of dissolution of
Grecian culture, returned to the ancient
dogmatism, with particular sympathy for
Eclecticism and Pythagoreanism.
But the Academy survived also these tendencies
of the New Academy, and assumed its ultimate form
in Neo-Platonism, which represents the last
grandiose effort of Greek thought to solve the
philosophical problem, by developing dualism into
emanative pantheism.
