Where our soul comes from
and where it goes when we
die
The Analogy of the Cave
In Plato's Republic book VII, Plato attempts to illustrate his theory of the forms by showing a
dialogue involving his teacher Socrates. The analogy begins in a cave where a number of prisoners
are bound by their necks and legs so that they cannot turn around. They have been this way since
birth and know no other life than this. Behind the prisoners are a low wall, a walkway and a fire that
burns. From time to time individuals carry objects like marionettes in front of the fire and shadows
are cast against the wall in front of them. The prisoners observe the shadows that flicker before
them and have developed a game over time. They try to predict the movements of the shadows.
They associate the sounds made by the individuals with the shadows as this is all they know. They
think of them as true reality.Plato asks us to imagine that one of the prisoners were to be set free.
He would stand with some pain and become dazed and confused by the bright fire light.
He would struggle to adjust to his new view of the environment. He would quickly realise that the
shadows he saw on the walls were not the real objects themselves. Plato suggests that if the prisoner
were led to the entrance to the cave he would have to struggle up the steep and jagged rocks to
climb out of the cave. Once outside the prisoner would further struggle to understand the new world
that was around him. At first he would simply focus on the shadows that objects cast in the sun. But
given time he would be able to see objects as they really are, in full shape and colour. Once the
philosopher is enlightened Plato suggests that they will return to the cave to tell others of their
enlightenment. He suggests that if the philosopher were to try to tell the others in the cave that
there was a whole other world outside the cave they would laugh at them. If they persisted to try
and convince them that this was the case then the prisoners would be prepared to kill them.
The Prisoners represent
everyday people
The shackles that bind the
prisoners represent the five sense
The shadows represent the false images,
what we see in the realm of shadows
The fire represents the apparent
good, or the false form of the good
The people who carry the objects represent
the order of the time, in this case the
Athenian Government
The difficult path out of the cave represents
the difficult journey of enlightenment that
every philosopher must travel
The outside world represents the realm of
the forms and the sun represents the form of the good
The prisoners who reject the enlightened one represent
people willing to kill in order to protect the false order
they live in. In this case the Athenian Government.
The Demiurge
Responsible for fashioning and
maintaining the physical universe
Discussed in dialogue by Timaeus
Translates to craftsmen
"Unreservedly benevolent"
The world remains imperfect,
however, because the Demiurge
created the world out of a chaotic,
indeterminate non-being.
Considered un-created and eternal
Aristotle
The Prime Mover
Exists by necessity
Pure actuality (has no potential to change)
Is the final cause (see four causes)
Is the goal of all action
"Unmoved mover"
Transcendent
Can be likened to a magnet
Described in Aristotle's writing,
Metaphysics
Everything is in constant motion
Heraclitus "You can never step in the same river twice"
The four causes with example
of a house
The formal cause
The shape of an object,
for example a cube with a
triangle on top
The difference between a mere collection of cells and a
human body is that a human body has properties and
functions that come from a particular arrangement of the
right kind of cells doing the right kind of things.
The efficient cause
The designer of an object, for
example and architect
Efficient causes answer the “what did that”
question, but do not answer how it was done.
The material cause
What the object is made of, for
example bricks and glass
The material cause also explains the general
sort of properties of something. Wooden boxes
burn because they are made out of wood.
The final cause
The ultimate purpose of the
object, for example to provide
shelter and be lived in
Why do balls break windows? The final
cause says that because balls are hard and
windows are brittle, they break.
OTHER IMPORTANT
THINGS TO NOTE
The third man argument
A criticism of Plato's realm of the forms, it argues that everything in the realm of
the forms must be based off of something else, a form of a form. Then this form of
a form must also be based off of something else and since there cannot be an
infinite chain of forms, due to self contradiction, Plato's theory no longer works
The soul and the analogy of the knife
Aristotle believed that after
death the soul also died.
The analogy of the knife is one that
Aristotle uses to illustrate his point
about the soul. He argues that once a
knife is bluntened it is dead as it can
no longer fulfill its purpose. Aristotle
links this to the soul, once the soul no
longer has a body it can no longer
fulfill its purpose and dies.
