Greeks Flashcards
key messages of the story of the cave
- this world is not real but the world of the forms is
- the knowledge that we gain is through the mind
- only philosophers have this knowledge so they should rule
- philosophers are the ones who know what is good
Weaknesses of the story of the cave
- it is not clear why philosophers must rule if this is the shadow world
- information we get through our senses help use to survive (can’t reject empiricism)
- plato doesn’t give proof or how they relate
- guilty of elitism, philosophers are people
Key understanding of forms and particulars
- idea that we recognise but can’t easily define do exist - they are invisible and intangible but are known to the mind
- each from is one single thing with many particulars
Aristotle four causes
Material, formal, efficient, final
- key knowledge come from empiricism
- it illustrates that the world is real
- the world and everything in it has a purpose
Key features of the prime mover
- immutable
- eternal
- perfect
- impassive
- non-physical and immaterial
- it is the cause of change and draws everything to itself
- can only think of itself
- the final cause
- pure actuality
Attributes of both the prime mover and God
- good
- eternal
- first cause
Aristotle supports of empiricism
- a posteriori is more useful for knowledge of the world around us
- we could not have thought of most things without the senses
- senses can deceive us
- it is hard to understand how we get ideas
Form of the good vs prime mover
- BOTH: eternal, immutable, necessary, outside the universe, perfect, transcendent
- PRIME MOVER: final cause, pure actuality, no potential, impersonal
- FORM OF THE GOOD: illuminates the mind, participates in all the forms, highest form, good
Hierarchy of the forms
1) form of the good
2) form of beauty, justice, truth, equality
3) abstract ideas
4) mathematical reasoning and science
- ———————————————————
5) material objects and opinions based on senses
strengths of rationalism
- more to the world than meets the eye
- a priori knowledge
- we have a sense of justice or beauty that seems to be innate, we ‘just know’
- reason makes more sense of reality and what we experience
- senses deceive us so we have different opinions about what is good because reason is not being used well
- we cannot rely on senses and observation to gain knowledge as they deceive us - reason is more reliable
weaknesses of rationalism
- how can we know without the sense
strengths of empiricism
- knowledge gained a posteriori
- need senses for learning + surviving
- there is no evidence of the existence of another world outside of the senses
- we can use reason only after we have experienced and observed things in the world
- we disagree on right and wrong when we use reason, it is better to use observation
- learning is more than than just remembering eg there is more to the salve boy than just remembering, he was sent through the steps
weaknesses of empiricism
Sense can decieve us
strengths of the prime mover
- impassive prime mover seems more logical than God
- prime mover avoids problem of evil
- we can see natural things seem to have telos and are drawn towards an end goal or purpose eg acorn
- prime mover helps to explain the movement and change
- explains why there is perpetual motion - the planets move in predictable rotations
- it gives a final reason why as it is the final cause
Aristotle - causation
- most objects conform to four causes
- four causes focus on purpose + meaning, we cam determine if something is good or not
- the claim that everything has a purpose is subjective (eg purpose of life is a matter of choice)
strengths of Plato
- We can recognise things that are similar even if we can’t explain exactly what it is
- without forms we can’t explain sameness
- ideal standards: absolute unchanging moral rules, form of good gives an absolute idea of goodness
- use of rationalism - is there more than meets the eye, how do we know?, can’t trust our senses
- analogy of the cave is universal and timeless
- philosopher kings - do they make the best leaders because they use reason?
- we can see things in the world of appearances change an die
- form of beauty and justice are concepts that don’t change
weaknesses of Plato
- Wittgenstein - rejects ‘one over many’, there is just a series of overlapping characteristics
- the third man argument - there is nothing to stop asking what the form and particulars have in common and need a third to explain
- problems with new inventions and extinctions
- evolution means explaining what objects have in common
- does not use empirical evidence
- if there is one form of the good why do we disagree over right and wrong
- analogy of the cave is a weak method of reasoning
- philosopher kings - he is guilty of elitism, practical skills are more important than using reason
- using reason is hard
- change can be seen as better than immutability
Plato’s support of rationalism
- a priori knowledge gives certainty (only in logic and maths)
- number of things that are hard to know without expereince
Attributes of God (to compare to prime mover)
- all powerful
- all knowing
- interacts with and loves the world
strengths of Aristotle
- you can see the four causes today
- the final cause gives things a sense of purpose
- it is based on empiricism which can be tested
- material cause is obvious - all things must be made of physical matter so this is a useful basis for our knowledge
- efficient cause explains the process of change
- formal cause helps us to understand what gives something its shape and characteristics
- final cause helps to explain why everything has a purpose
- if an object fulfils its purpose then it is good - good is intrinsic to the object itself
- empirical theory is applicable to life and scientific enquiry
weaknesses of Aristotle
- some things has no purpose
- even if parts have a purpose the whole may not (fallacy of composition)
- having a purpose is a mental process
- existentialism - things just are
- cannot din the four causes in everything eg beauty
- Aristotle moves away from empiricism when he suggests the prime mover
- our senses can deceive use
- there is more to life than sense experience
- HUME: cause and effect could be correlation
- goodness does not necessarily have to link to purpose
weaknesses of the prime mover
- difficult to understand something as perfect with no knowledge of the world
- not involved in the world and not worthy of worship
- if its responsible for everything where did matter come from
- purpose is a human construct so we give things purpose - there is no external purpose so there is no need for a final cause
- you have to move to rationalism to understand the prime mover it is no longer an empirical concept
strengths of the story of the cave
- shows that our senses do deceive us - what we sense is only the partial reality
- senses can trap us, we can be closed minded and not want to consider other views or ways of thinking
- relying on reason is like becoming a philosopher
Aristotle’s prime mover is more successful that Plato’s form of the Good
- prime mover explains the reason why there is change in the world, because everything is being drawn to its perfection
- Aristotle is based on sense experience
- Plato does not clearly explain how the form of the good participates in objects or concepts in the world of appearances but the prime mover gives a clear explanation
Plato’s form of the good is more successful than Aristotle’s prime mover
- form of the good explains change in the world of appearances - things here decay but participate in the perfect
- prime mover can’t be observed with the sense, the form of the good is not part of the material world - important to use reason for truth
- form of the good explains how we recognise goodness in lots of different things
(- Aristotle’s prime mover moves to rationalism so is criticised in the same way the the form of the good is)
