1. Ancient philosophical influences Flashcards
Plato
AN Whitehead quote about Plato
“All of philosophy is a footnote to Plato”
Plato
Understanding of reality
- PW always changing, Forms = unchanging ∴ has certainty PW lacks.
→ “You can never step into the same river twice.” - Heraclitus 5000BC - Dualist - belief of two worlds.
- PW known through sense experience (empirical observation), can be misleading.
- PW given reality by Forms; physical phenomenoms ‘participate in’ their ideal forms.
Plato
The Forms
= concepts, ideals and universals that help us understand PW.
= superior as unchanging.
* known through a priori knowledge.
* Must have encountered them before birth, anamnesis, → must have immortal souls that are capable of living w/out physical bodies.
* highest = good, illuminates them all.
Hierarchy of forms
- Good.
- Beauty, justice, truth.
- Mathematical, geometric.
- Objects we experience
Criticism of form of good
- Aristole - virtue required to do good, not just an understanding of goodness + cannot be one unified form of the good which captures all the diverse forms of goodness in this world.
- Plato = optimistic or inventing the form of the good because he wanted philosophers to rule society.
- Nietzche - Form of good = ‘dangerous error’ + claimed attempt to justify their emotional prejudices e.g. desire for power.
Plato
Alagory of the cave
- Compares PW w/ dark shadowy cave + WoF ‘sun-filled’ real world.
- Shows importance of philosophy + illustrates how knowledge gained through senses is inferior to knowledge of Forms.
- Prisoners know nothing outside of cave = sense experience only shadows of truth → accept them at face value. Don’t Q anything, imprisioned by ignorance.
→ prisioner leaves cave + enlightened knowing truth.
PW demonstrates how senses are misleading.
Real truth found through philosophy leads us to the Forms.
Plato
Strengths
- Helps us understand why there is imperfections, doesn’t rely on God.
- Explains why we recorgnise things differently e.g. beauty → without being taught, must of had a collective experience.
- Asks fundermental Q’s about life, meaning and reality. Encourages to question in order to learn.
- Lack of evidence = forms → immaterial.
- Influenced ideals like Narnia.
Plato
Weaknesses
- Karl Popper = Plato tries to find certainty in a world where it can’t be found.
- Can’t be proved, no impirical evidence.
- Believes senses are insuperior, yet humans have relied on them for 1000s of years.
- Dawkins = “To talk about a transendent world is nonesense.”
- Forms = no pratical use e.g Dr. dont use perfect form of health, but think about individual needs.
- Unlikely everything has an ideal form. Cancer? = contradiction as forms meant to be perfect.
- Mel Thompson = “Fails to illustrate the attractiveness of PW… scene of cave hardly represents the delights of senses.”
Aristole
Understanding of reality
- If anything other than PW exists, we have no way of knowing.
- Studied under Plato.
- Learnt by observing the PW = empiricist.
- Can be explains in 4 ways, account for and explain phenomena of PW around us.
Aristole - four causes
1st cause
Material cause → explains what something is made up of, helps understand aspects of it.
Aristole - four causes
2nd cause
Formal cause → explains shape and from something takes, or identifying features.
Aristole - four causes
3rd cause
Efficent cause → explains activity that makes something happen, brings about change + actualises potential.
Aristole - four causes
4th cause
Final cause → somethings purpose or reason for existing at all.
Telos = an end, fulfilment,
Aristole
Prime mover
- Noticed movement runs out (ball rolling), but planets etc. still had movement. ∴ must be a PM to account for everything always changing.
- PM creates motion as objects are attracted to its perfection.
- Final cause of universe.
- is a pure mind eternally contemplating itself – unchanging and attracting everything in the universe towards it, thereby causing the motion and change we experience.
Aristole
Prime mover criticisms
- Issac Newton = proved wrong that motion runs out, actually motion just transfers into another type of energy.
- So stars/planets dont need special explaination like PM.
DEFENSE = empirical evidence use correct, Newton used this himself.
