The Dialogues
- Plato wrote a number of dialogues between Socrates and his contemporaries
- They are usually divided into three periods
- Early: concerning Socrates and his unsuccessful quest for an account of virtue (Euthyphro)
- Middle: developing Plato's own positions (Phaedo, Republic)
- Late: examining problems with Plato's views
|
Philosophy and Death
- Socrates's imminent execution sets the stage for the dialogue
- He maintains that one aim of practicing philosophy is to prepare for death
- Philosophy frees the soul from the body as much as possible in life
- So the philosopher is thought by the many as being close to death
|
The Body
- The body is a hindrance to knowledge
- There is no truth in sight, hearing, etc.
- Reasoning comes closest to revealing reality
- We reason best when the body is not troubling the soul
- The body gives rise to needs and desire, which in turn produce disruptive conflict
|
Imperceptible Reality
- There are such things as:
- The Just itself
- The Beautiful itself
- The Good itself
- Each of these is the reality which other things essentially are
- They should be tracked down using pure reason
|
Virtue
- The philosopher, the lover of wisdom, is contrasted with the lover of the body
- To face death "courageously" through fear of greater evil is inconsistent
- To be moderate in order to enhance pleasure is to be mastered by pleasure
- Only the philosopher can behave truly virtuously, by despising the body
|
Immortality
- The soul can attain true knowledge only if it is separated from the body
- True knowledge can be attained after death only if the soul continues to exist
- How can it be shown that the soul is immortal?
- This requires "a good deal of faith and persuasive argument"
|
Argument From Opposites
- Opposites come to be only from opposites
- Life is the opposite of death
- So, life comes to be through death
- Life can come from death only if the soul already exists without the body
- The soul exists without the body only due to the death of a previous body
- So, the soul exists after death
|
Recollection and Immortality
- The example of Meno's slave supports the theory that all learning is recollection
- If the theory is true, then what the soul knows when in its present body it must have recollected from a time before it was in that body
- If the soul existed outside the body, then it is probably immortal
|
|
Perceptible Objects and the Forms
- Equal objects are considerably deficient with respect to the Equal itself
- They strive to be the Equal itself but fall short
- We cannot know of this deficiency unless we alreadly know the Equal itself
- If we already know the Equal itself, then we recall it when we say that preceptible things are equal
|
The Nature of the Forms
- The Equal itself is the standard by which things are equal to each other
- It is one of the Forms, like the Beautiful, the Just, the Good, the Pious
- These things certainly exist
- Each one is simple
- Because they are simple, the Forms are not subject to change
|
|
Knowledge of the Forms
- The soul can know the Forms, but not through bodily experience
- So it either knew the Forms from birth, it acquired the knowledge at birth, or else it recollected them
- If the Forms were known from birth or were acquired at birth, we would always know them
- But many people do not know the Forms
- So, the Forms are known through recollection
|
Argument from Recollection
- The soul can only know the Equal itself by recollection
- Recollection requires existence before birth
- So, the soul existed before birth
- If the soul existed before birth, then it existed after death [from prior argument]
- So, the soul exists after death
|
Argument from Simplicity
- If the soul ceases to exist, it must be because it it has decomposed
- The Forms are simple and incapable of decomposition
- The soul resembles the Forms in its simplicity
- So, the soul is incapable of decomposition
- So, the soul cannot cease to exist
|
Purification
- The life one leads determines ones condition after death
- Polluted souls will be unhappy
- Eventually they will be reincarnated into an animal suited to their vices
- Only the completely pure can join the gods and attain true knowledge
- This is why philosophy is training for death
|
The Harmony Objection
- The Pythagoreans conceived of the soul as a harmony and the body like a lyre
- The harmony ceases to exist when the lyre is destroyed, so the soul would cease to exist upon the death of the body
- But a harmony is formed after the lyre, so if the soul were the harmony of the body, recollection would be impossible
- And we could not explain virtue and vice in terms of harmony and disharmony
- So the harmony account of the soul is rejected
|
The "Cloak" Objection
- The soul is said to outlast many bodies because it existed before those bodies
- Similarly, a man exists before many cloaks he wears out, and yet the last cloak of a person survives after the person's death
- So the soul might be wearing its "last body" (which survives as a corpse after death)
|
The Forms as Causes
- Answering the cloak objection requires an investigation into causes
- Physical explanations of causes are inadequate
- The Beautiful itself exists, and is beautiful
- E.g., the Odd can never be the Even
- The cause of something's being beautiful is explained by the thing's sharing in the Beautiful itself
|
Admitting the Opposite
- Socrates must make a digression about the causes of generation to answer the cloak objection
- He explains change through the Forms
- Forms do not admit of their opposites
- E.g., the Odd can never be the Even
- What necessarily brings along a property does not admit the opposite of that property
- The triad is odd, and so it cannot be even
|
The Final Argument
- The soul can only bring life to the body into which it enters
- So, the soul does not admit the opposite of life
- The opposite of life is death
- So, the soul never admits death
- So, the soul is deathless
- What is deathless is indestructible
- So, the soul is indestructible
|
The Underworld
- When the soul leaves the body at the body's death, it journeys to the underworld
- Socrates gives a detailed description (which he admits is not certain) of the underworld
- The wicked receive repeated punishment until they repent
- The virtuous are freed to live in the sunshine in beautiful dwelling places on the surface of the earth, and he hopes to join them soon
