plato Flashcards
what is the logic behind using our senses
we can identify things like chairs and tables - so is it possible to see courage or justice
plato justice example
if you borrow a pruning knife from your neighbour, it is just to give it back. however, if the neighbour had become mentally ill, and a danger to himself and others, so it would not be just to return the knife.
= there is nothing about the physical action itself that can tell us that something is just or unjust as we cannot see as we can see a table. rather, we reflect using reason. ideas like justice are objects of reason and not perception.
what is a form definition
an entity that can be known through reason alone and not through our senses.
what does plato reject about values
he rejects the notion that value is a matter of opinion. in the end there is a fact of the matter about what is just or good or beautiful.
how does plato prove that these forms exist
we disagree for example that abortion is wrong or right, and we argue that things are true not matters of opinion otherwise we wouldnt argue. so if they are objective, they must exist.
plato’s belief of forms
FORMED FROM MATHMATICAL BASED LOGIC
-our minds can access entities called forms through reason and thereby giving us knowledge of values.
-forms are imperceptible and they are unchanging (as they are objective so therefore always true). there are forms corresponding to major value terms; justice, beauty and goodness.
-Plato thought access to the forms was not impossible and progress is made through every rational debate
-our world is the material world and is full of imitations and shadows of the forms. the forms exist in the world of the forms
-when we are born, we have a dim recollection of the forms - as we can instinctively recognise something as beautiful without being taught it.
=therefore, Plato concluded that it must be that we have and immortal soul whihc was once part of the world of the forms.
what type of knowledge is gained from senses
empirical knowledge
what type of skill is reasoning
a priori - innate
the hierarchy of forms
- form of good which is the ‘form of forms’ as all forms have some good in them
- higher forms eg beauty, justice
- material objects + images.
plato’s analogy to sight
sight requires both light (good) and the eye to see clearly. plato’s implication is that without the knowledge of the form of good, one does not see clearly, like trying to see in complete darkness.
plato’s cave analogy
people chained to chairs and the only light in the cave is from the fire behind the wall that is behind them. behind this wall, people are walking, carrying statues - casting the shadows on the wall in front of the prisoners.
one of the prisoners is freed and he turns around and sees that the shadows are made by the statues. he leaves the cave and sees the importance of the sun - now he doesnt want to go back underground.
he remembers his friends in the cave and wants to go back to teach them about the reality. he goes back but his eyes cannot adjust to the darkness. the prisoners decide to never leave the cave and put to death anyone who tries.
what does plato’s cave signify
-the importance of questioning everything in order to distinguish between the real world and the material world.
-the cave = the material world, the shadows = lies/comfortable realities told by society, the outside = real world, the return to the cave = a philosopher’s duty to educate the world.
strengths of plato’s theory of the forms
- Brian Davies: analogy of the cave is useful to illustrate the theory of the forms.
- Stephen Evans: plato offers a rational argument for the existence of another reality/world.
- Bryan Magee: encourages people to seek enlightenment rather than being caught up in the material world. he says ‘the theory that there is another world than this gives value and meaning to our present world’
- effective argument to evil and suffering. it is the material world so therefore not perfect; it is the actions of material beings that causes suffering.
- helps us understand concepts that seem innate - as nobody has invented beauty or justice.
- logical, reasonable, clear and coherent
weaknesses of plato’s theory of the forms
- Hume and Dawkins woudl argue that Plato’s ideas about the physical world are counterintuitive - as it is not common sense to say that the world around us is an illusion as it seems so real. Dawkins would argue that the talk of a transcendent world is meaningless.
- Logical Positivists would question about opinion; how can two people always come to the conclusion of what is good/beautiful/just. people have there own opinion.
- Empiricists such as John Locke and Bertrand Russel argue it is not logical to argue for a world we cannot see. they would argue reality is based on sensory evidence an not reason
- Plato argues senses are inferior but they enable us to learn, communicate and survive. Dawkins supports this
- Plato doesn’t address the extent to what has a form eg is there an ideal form of a slug or cancer - he doesn’t fully explain his theory as it is difficult to accept its value.
plato criticisms about infinite regress
if we have knowledge about goodness - he argues we have knowledge about the form of the good. however, if we have knowledge about the form of the good, does this mean we have knowledge about the form of the form of the good.???????? philosophers debate this flawed infinite regress.
