The Platonic Forms


Concept of the Forms (or Ideas) is Platonic

Socrates unworldly, but not otherworldly
used as the mouthpiece for Plato's ideas
Presentation through Socrates is qualified in two ways:
1. Socrates is pursuing the best hypotheses available
2. Compares his presentation to a swan-song
Jokingly suggests he now has powers of prophecy!
Phaedo is the first presentation of the Forms
a careful and gradual argument

Central topic of the dialogue: What happens to the soul after death?

Existence of the Forms used to prove immortality, and
discussion of immortality used to present the Forms!
Shift in Greek concept of the soul
Homer: a 'gibbering shade'
similar to concept of Sheol in Genesis
good example of primitive conception of the soul: two souls
body-soul
free-soul
Pythagoras (6th c BCE)
reincarnation
conception of the soul in Phaedo
influenced by Pythagoras
soul = mind
soul must be purified
Other 5th c conceptions:
older view
dissolution of the soul
Mystery Cults
Causes of this shift?
literacy?
or two simultaneous developments?
a modification, not replacement, of traditional religion

Plato: A sharp division between body and mind

The pursuit of philosophy is a preparation for death
a turning from the body to the soul
The body is source of emotions, desires, fears, illusions
causes war; subject to disease
Only the soul can grasp truth and knowledge
Soul reasons best when it separates itself from the body
possible to limited extent while living
Only the dead can be true lovers of wisdom!
A true philosopher has no fear of death
philosophy a purification of the soul
a preparation for death
Virtues of philosophers are more logical than those of other men
courage
moderation
Wisdom a cleansing and purification
philosophical virtues purge the soul of desires and fears

Theory of Recollection

Presented to support argument for immortality of the soul
Meno
humans exposed to knowledge before birth & forget at birth
remember through proper questioning (Socratic dialectic)
or, as here in Phaedo, when we are reminded by an object
Two equal sticks bring to mind
The Equal itself! -- the Form of equality.
the equality of the sticks is imperfect
therefore we must have prior knowledge of the Equal
Similarly, beautiful, good or just people, things and actions are deficient in some way
They are not the Beautiful itself, the Good itself, or the Just itself

The Forms

Qualities:
1. Simple, unmixed with anything else
2. Unchangeable
3. Invisible
4. Divine patterns from which everything in the world is derived
this world is a collection of copies of the Forms
it is thus less real than the Forms (cf. the allegory of the cave)
Soul is like the Forms
Invisible, simple, unchangeable, deathless, divine
Thus it dwells in the same 'realm' before and after death
Therefore it gains knowledge of the Forms
(Nota bene: language is inadequate to express the nature of such a realm)
Forms actually exist in a higher, invisible, transcendent realm
not merely abstract concepts
Plato doesn't insist on the precise relationship between the Forms and the world
Any possible expression is a metaphor
a person 'shares' in the Beautiful
an event 'participates' in the Just
something 'imitates' the Good
through the Beautiful (the Good, the Just) all things
become beautiful (good, just)

Some observations

Plato's goal:
to ascertain objective truth
He believed reality can be known and that reality is rational
distinguished between the Real (the Forms)
and the not fully real (this world)
a secondary, or derived reality
yet he believed a true philosopher will engage the world, not withdraw
role of the "Philospher-Kings" in The Republic
least likely to abuse power

Summary of key issues

Socratic method or dialectic
inductive pursuit of universal definitions
worked from particular instances to generate abstract concepts
Plato goes beyond
abstract ideas not merely communicable thoughts
they are divine patterns
everything is thus a copy of divine Forms
A possible way of viewing this claim:
Plato was so impressed by the power of astract ideas that
1. he saw them as more real than the physical world
2. believed they were the source of everything in the world
3. believed they were 'higher' and 'realer' than everything in the world
they are intelligible
they are cosmic patterns
physical world derived from spiritual
Note that Plato reached these conclusions by reason alone
eye of the mind
Dawn of abstract thought
product of literacy
Plato's teaching on the Forms had little immediate impact
e.g., Aristotle disagreed
as a culture, the Greeks tended to focus on this world
But its ultimate impact was tremendous
Neoplatonism
St. Augustine
Boethius
the "Realists" in Medieval philosophy
