Theory of forms - origin
Plato noticed that the physical world was always changing - How could people attain true and certain knowledge ? He came to the conclusion that things in the world were in constant change thus can never be objects of complete true knowledge .. form of tree never changes and does not depend on physical circumstance for its existence
Theory of forms
Plato believed that all the material things we experience in the world around us are imitations of their perfect form - We gain true knowledge through reason and we recognise things for what they are only bcs of our knowledge of their forms .
Heraclitus
” You can never step into the same rive twice”
Forms continued e.g Justice
When we see someone doing an act of justice we recognise it as justice bcs we know what true justice really is as a concept .
Forms continued e.g Circles
we see things which are circular such as plates , clocks , wheels , we even draw circles in maths lessons but they will never be perfect circles however our mental concept of a circle is perfect but when translated in the the physical world it loses some of its perfections
More on the forms
Plato decided that we had some intuitions about the forms e.g beauty and it must be because we experienced them thus we have immortal souls and must have lived in the realm of forms before being born into the physical world .
The form of the Good
The most important of all forms - it illuminates all of the other forms and gives them their value and the rest of our knowledge . Goodness is seen as the purest , most abstract of the forms
Demiurge
Plato believed the world was created by a god he called the Demiurge - he made the world with that material already present , he tries to make the universe as good as he can but is limited and so the final result is not perfect but the best it could be . As the world is physical and so can be changed . The deimurge isnt the epitome of goodness but he is still good.
Plato evaluation
Richard Dawkins - it is nonsense to talk of an other world beyond the physical - the world may be changing but we can still study it with all its changes and processes and gain true and valuable knowledge .
Analogy of Cave
In the cave there are prisoners , they are chained in such a way that they can only face one direction , and sat facing the back wall of the cave , the only light available comes from a fire behind them . People go along the low wall carrying different objects as they pass the fire the shadows of the objects are reflected so the prisoners can see … however the reflection does not show the true nature of the objects similarly the voices they hear are echoes .. then the prisoners are released and a prisoner is shocked to find the truth ..things are not as they seem he does not want to accept this and runs back to fire but soon his eyes will become accustomed to light .. and will leave
Plato evaluation
Aristotle says the theory of forms is ridiculous when pushed to logical extremities it is hard to accept there may be ideal forms of negative qualities like jealousy or spite
