1、2.3 Classical Greek philosophy1.The Academy of Athens by Raphael,one of the greatest masters of the Italian Renaissance.2.Philosophy literally means“love of wisdom”in Greek.Pre-Socratic periodThales of Miletus was the first philosopher.In his famous book The History of Western Philosophy,Bertrand Ru

2、ssell wrote:“philosophybegins with Thales”,Miletus was a Greek city in Asia Minor.Thales predicted an eclipse which happened in 585 BC.We can say philosophy andscience were born together at the beginning of the sixth century BC.Plato listed Thales as one of the Seven Wise Men.Thales said thefundamen

3、tal substance is water,everything is made of water.3.Heraclitus was another Greek philosopher,nearly a century after Thales,also from Ionia.Heraclitus regarded fire as the fundamentalsubstance,everything,like flame in a fire,is born by death of something else.He believed“all things are flowing”,“You

4、 cannot step twice into thesame river,for fresh waters are ever flowing in upon you.”“the sun is new every day.”4.SocratesSocrates is one of the founders of Western philosophy.We know when he died in 399BC,but we dont know exactly when he was born.c.470,c here means circa,circa in Roman language is

5、about approximately and around sometimes.For lack of reliable sources,it is very difficult to findout the real life of Socrates,thus there is a term“Socratic problem”.The main source of Socratess life and philosophy is Platos dialogues.Hewas“hidden behind his best disciple,Plato”.But some facts are

6、clear:he lived entirely within Athens,he refused to write,he taught but refused tobe paid,and he was ugly.Cicero said Socrates was“the first who brought philosophy down from the heavens,placed it in cities,introduced it intofamilies,and obliged it to examine into life and morals,and good and evil.”S

7、ocrates made great contributions to the field of ethics andepistemology，the philosophy of knowledge.5.The Socratic Method is a method through dialogue,by asking and answering questions to stimulate critical thinking and finally reach aconclusion.Socrates was a“gadfly”of Athens.Gadfly is a large fly

8、which is very annoying,if we say someone as a gadfly,that means hedeliberately annoy or challenge other people,especially people in authority.Someone went to Apollos temple in Delphi asking a question:“ifanyone were wiser than Socrates”;the Oracle was“no one”.At first Socrates didnt believe it.He ta

9、lked to some“wise”men in Athens,statesmen,poets,and artisans.He found all of them were not wise at all.Finally he realized he was indeed wiser because he was the only oneaware of his own ignorance.Socrates made these people very embarrassed,they wanted to get rid of this gadfly,and this led to the t

10、rial ofSocrates.He was pronounced guilty of two charges:one,against the gods,searching into things under the earth and above the heaven,and two,tocorrupt the youth by teaching his beliefs.He was sentenced death by drinking a poisonous beverage of hemlock,a poisonous plant.We mentioned before the Soc

11、ratic paradox:I know one thing that I know nothing,paradox is a statement that contradicts itself.Socrates never stopped searching truth and virtue,he said“The unexamined life is not worth living.”He believed the best way for people to livewas to focus on the pursuit of virtue rather than the pursui

12、t,for instance,of material wealth.”Socrates believed“ideals belong in a world only thewise man can understand”,thus only the philosopher is suitable to govern others.6.This is the death of Socrates,at this moment I believe Socrates is saying:I know one thing that I will die,but Im not afraid,I refus

13、ed toescape because I respect the Athenian law7.Plato 428-348BC was the best student of Socrates,the founder of the Academy in Athens,the first school of higher learning in the Westernworld.Plato had witnessed the Peloponnesian War,the falling of Athens,the brutality of the Thirty Tyrants,and the de

14、ath of Socrates.He developed ahatred for Athenian democracy and distrusted ordinary peoples ability to know the justice.He believed vice and failure of government and societyresult from ignorance of the truth.8.The Republic.Platos best-known work is The Republic;the purpose of this Socratic dialogue

15、 is to define what justice is.Plato believed Godhas created three kinds of men.First made of gold,second made of silver,third made of brass and iron.Plato divided citizens into three classes:first made of gold the guardians,second made of silver the soldiers,third made of brass and iron the common p

16、eople.Only the guardians shouldhave political power to rule,and the rulers must be philosophers.What is justice?Everybody doing his job and not being a busybody.Busybody issomeone who interfere other bodys business.And this is the most difficult part.9.The theory of Forms or Ideas is an idealist vie

17、w.It is partly logical,partly metaphysical.The word“metaphysics”in Greek meaning beyondphysics.Metaphysics is the study of being and knowing in a highly abstract way,tries to answer questions like what is there?And what is it like?“Form”in Greek means“shape”or“appearance”,but Platos Form or Idea mea

18、ns true knowledge,something eternal,timeless,universal.What is a Form?All horses are different,male,female,old,and lame,all of them will die.But there is something all horses in common,that is theForm of horse,and all Forms not from the world we live.Plato believed there are two realms,realm here me

19、ans world.The first is the materialworld in which we live,this world is imperfect,and everything is tangible and keeps changing.Tangible means substantial and touchable.Thesecond is a non-physical world,the world of Forms or Ideas.Forms are perfect,eternal and beyond the experience of senses.World o

20、f Formslike sunshine,the material world we live like shadow.Everything we see in this world is not real;they are merely shadows of the eternal Forms orIdeas.Plato believed our souls belong to the world of Forms;it existed before it inhabited the body.To seek the truth,the soul has to return to itsor

21、igin to get the true knowledge.110.Allegory of the cave.Allegory is a short moral story.This story was from Platos Republic told by Socrates.In a cave,some prisoners satwith their hands and feet chained.They faced a wall.They were watching shadows on the wall.The shadows were from their back,people

22、wereholding up various figures in front a fire.The prisoners thought the shadows are reality.Only one realized this is not truth.He went out the cave,hewas a philosopher.But most people refuse to leave.In this story,the cave is a symbol of the real world,the chains represent ignorance,and theshadows

23、 represent what people see in the real world,the freed prisoner represents the philosopher who found the truth.11.Aristotle 384-332BC Along with his teacher Plato,Aristotle is the“Father of Western Philosophy”.He was born in Macedonia.His father isa doctor.He studied in Platos Academy for twenty yea

24、rs.In 343 BC,he was invited by Philip II of Macedonia to be the tutor of his sonAlexander.Aristotle left many works.His interests and writings covered many fields:political theory,metaphysics,logic,ethics,aesthetics,rhetoric,language,poetry,drama,music,physics,biology,and zoology.His works formed th

25、e first comprehensive system of Western philosophy.Aristotlescontribution in logic and science became an authority and remained unchallenged until the modern age.12.Empiricism.Not like Platos idealist view.Aristotle in favor of the method of observation,systematic investigation and explanation.Someo

26、nesays he is the first Empiricist.Empiricism is a theory that states we should rely on practical experience and experiments,rather than on theories,asa basis for knowledge.Aristotle said:“Plato is dear to me,but dearer still is truth”It is a very inspiring maxim,isnt it?13.Key Words：Socratic paradox，Metaphysics，The theory of Forms，Allegory of the cave，Aristotle2
