Plato Flashcards
What is a rationalist?
uses reason to derive truth
what is an empiricist?
uses empirical evidence of the world to derive truth
what did Plato believe about the world?
“because the material world is changeable it is also unreliable”
how did al ghazali support rationalism?
pointed out that what we experience can be deceived and influenced in the same way that our senses are – he gave the example of the fact that when looking at the sun you assume that it is small, when in reality it is actually huge
What is plato’s cave allegory?
- The allegory states that there are prisoners chained together in a cave.
- Behind the prisoners is a fire, and between the fire and the prisoners are people carrying puppets or other objects. This casts a shadow on the other side of the wall.
- The prisoners watch these shadows, believing them to be real.
- Plato tells of one prisoner (Socrates) who becomes free.
- He finally sees the fire and realizes the shadows are fake.
- This prisoner could escape from the cave and discover there is a whole new world outside that they were previously unaware of.
- When the escaped prisoner left the cave, he saw the real world, the sun, the light, which represents the true world.
- This prisoner would believe the outside world is so much more real than that in the cave. He would try to return to free the other prisoners.
- Upon his return, he is blinded because his eyes are not accustomed to actual sunlight. The chained prisoners would see this blindness and believe they will be harmed if they try to leave the cave. They attacked the prisoner, believing he was mad, because he could no longer play the game where they guessed what shadow appeared next. He was outcast.
3 points supporting the cave allegory/reason
- senses can deceive us
- subjects based on reason alone leave no room for ambiguity; they lead to a definite conclusion so are likely to be true
- reason leads to agreement on ethical truths eg most cultures would agree that killing is wrong
3 points against the cave allegory/reason
- reason is based on knowledge that is gained through senses
- reason is not always accurate; can be manipulated by drugs, alcohol etc, or it can change over time, or because definite conclusions do not make things a reality
- everyone has a different moral code so may use different reasoning to justify different truths, or it can be wrong using reason
What is Plato’s theory of forms?
- The sensory world is not the real world, because it is in time, in space, impermanent, and imperfect.
- There is another world called the Realm of Forms, which is the real world. It is the truth. It is a perfect, fixed, timeless, spaceless world. A world of reason.
- Forms are perfect versions of everything in the sensory world. They are perfect as they are eternal and immutable.
What is the hierarchy of forms?
The form of the good is at the top, and underneath are the forms of justice, truth, beauty, equality and courage. Underneath those are the forms of physical objects in the world. Lastly are the forms of maths and science.
what is innate knowledge? and what evidence suggests we have it?
Before we were born, the soul was in the realm of forms, so holds innate knowledge of the forms.
- Slave boy answering a tricky maths question
- Slave boy asked to find two completely equal sticks, and succeeded, showing innate knowledge of the concept of perfect equality.
- Child prodigies eg Mozart.
What is Chomsky’s universal grammar?
Chomsky argued that we are born with some rules of grammar hard wired into our brain i.e. this knowledge is innate. This is why children find learning language much easier than adults.
What is Descartes’ pencil in water example?
Pencil refracts but we know it is straight - senses can deceive us
How does Anselm support the ROF?
said we share an innate sense of justice
How does descartes support plato?
Descartes was also a rationalist. He agreed that we have concepts i.e. innate knowledge that exist in the mind first and then help us construct reality.
What is a strength of the ROF?
- Evil or negative things do not exist, they are the privations of goodness.
- E.g. blindness is the absence of sight.
