ancient philosophy Flashcards
rationalism
human reason source of all knowledge and truth
cave analogy summarised
-prisoners in cave chained, fire illuminates shadows and think they are real
-one prisoner released through hard journey out of cave and sees light, truth out of cave
-prisoner sees how much better this world is
-if prisoner returns to cave he wont be able to see well in semi darkness and people will mock him
what does cave represent in analogy
-out material world
-prisoner trapped in this lesser world only using their senses
-what prisoners think is real only shadow of real objects
-deceived by senses
what does sun represent in cave analogy
-the highest of all forms- form of the good
-form of good illuminates all other forms
-enables the forms to be known through reason
cave being inferior to outside world meaning
just like cave inferior to outside world
-like how senses less reliable than reason for using to gain knowledge
meaning of prisoner being mocked by people in cave and not being able to see if he returns
-could be reference to socrates
-he was executed because he corrupted minds of youth in athens
-encouraged them to question and use rational thought
-shows how entrenched out thinking can be
-how we are reluctant to use our reason and rather rely on our senses
arguments arguing analogy of cave us useful today
-shows senses deceive us, what we experience or observe only partial reality, shadows seen by prisoners inferior to real world outside cave
-truth only accessible to philosophers
-senses can trap us like chained prisoners, use senses instead of reason
particulars
changing things we witness in world of senses for example roses in garden
immutable
unchanging
form
platos description of perfect unchanging concept or ideal in world of form eg, form of good
anamnesis
soul remembering from the world of forms
world of apperances
our world
-thing appear to be real but will die
-change or decay
-illusion of reality but poor imitation of reality
-
why do we disagree on beauty according to plato
-because our senses deceive us
-our opinions based in senses which are unreliable
-
world of forms
-immutable
perfect
eternal, forms or ideals
-reality remains constant
-can be understood through reason rather senses
-why person good and pen beautifull
-for plato- using reason we work out particulars participate in form of good, ideal concept of goodness
heirachy of forms
form of good
-form of justice, form of beauty, equals
-abstract ideas
-mathematical reasoning
-above all in world of forms
-material objects and opinions based in senses from world of apperances
the theory of the forms make sense arguments
-we observe in this world change and decay, nothing perfect and changing but world of forms everything perfect and eternal
-world of forms real world, like world outside cave, better than inside cave
-can be deceived by our senses so better to use reason
-world of forms has ideal concepts, beauty justice truth, immutable, recognise beauty in something because they participate in form of beauty
the theory of forms makes no sense arguments
-change better than unchanging things, without change we couldnt progress in world
-material world all we know and have evidence of, senses help us learn and survive
-reason difficult, better to rely on senses as provide verifiable evidence
-if one form of good then why are there disagrees of about what true goodness is
where did aristotle think knowledge came from
from senses, experiences and observations
-no need to look outside this world for answers
motus
aristotle says everything in world changing
-things going from potentuality to actuality because of external forces
-
aristotles four causes
describe process of change observed by our senses
material cause
matter of substance something is made of
-doesnt yet explain how or why motus occurs
efficient cause
-process of something coming into existence
-silversmith who makes ring
-describes process of change
formal cause
-how we know something is
-shapes and character
-explains motus by describing result of the change from material cause through efficient cause into object it is
final cause
describes the telos or purpose, why object is there
-most important to aristotle
aristotles four causes give true picture of reality arguments
-material cause obvious, everything must have physical matter
-efficient cause explains process of change motus,
-formal cause helps us understand what something is, form of object its soul
-final cause telos, questions why world or objects are they way they are
-it object fulfills its purpose its good, goodness not found elsewhere but intrinsic to object
-empirical theory application to everything
