PLATO:

Plato (428-347 BC) was one of the most creative and influential thinkers in Western philosophy.The chief student of Socrates.Plato's major work was on political theory,Plato wrote that society can enjoy prosperity and harmony only if it places people in working categories or classes according to their natural abilities.He thought that people should find out their natural abilities and use those abilities to their fullest capacity-as administrators,as military men,or as craftsmen.Most important,the head of state should not be an average or mediocre man.Instead,society should be led by a very wise and good man-a "philosopher king".
Everyone,both in human society and in animal society,is influenced by the modes of material nature; goodness,passion and ignorance.By scientifically classifying men according to these qualities,society can become perfect.
Plato also observed social divisions.However,he advocated three divisions.One class consisted of the guardians,men of wisdom who governed society.Another class consisted of the warriors,who were courageous and who protected the rest of society.And the third class consisted of the artisans,who performed their services obediently and worked only to satisfy their appetites.
Yes,human society does have this threefold division also.The first-class man is the mode of goodness,the second-class man is the mode of passion,and the third class man is the mode of ignorance.Plato's understanding of the social order was based on his observation that man has a threefold division of intelligence,courage and appetite.Plato believed that man's position is marginal-between matter and spirit-and therefore he also stressed the development of the body.
Plato thought everyone should be educated to work in whatever way is best suited to awaken his natural moral goodness.But moral goodness is not enough,because simple morality will not satisfy the soul.One has to go above morality.Of course,in this material world morality is taken as the highest principle,but there is another platform,which is called the transcendental platform.Man's highest perfection is on that platform.However,because western philosophers have no information of this platform,they consider the material mode of goodness to be the highest perfection and the end of morality.But in this world even moral goodness is infected by the lower modes of ignorance and passion.You cannot find pure goodness in this material world,because pure goodness is the transcendental platform.To come to the platform of pure goodness,which is the ideal,one has to undergo austerities.One has to practice celibacy and control the mind and senses.In this way,one can rise to the platform of pure goodness.
Plato thought the state should train citizens to be virtuous.No one should be trained in everything; that is a waste of time.
If one is inclined toward production,business,or agriculture,he should be trained in those fields.If one is philosophical,he should be trained as a philosopher.If one is materialistic,he should be trained as a warrior.And if one has ordinary ability,he should remain a laborer.The four classes of society are organized by their symptoms and qualifications.One should be selected for training according to his qualifications.
Plato believed that the student's natural tendency wouldn't come out unless he practiced everything.No,that is wrong because the soul is continuous,and therefore everyone has some tendency from his previous birth.Astrology can help if there is a first-class astrologer.Plato's method of education was imperfect because it was based on speculation.A person may be born in the family of guardians,and be a laborer.It is a question not of birth but of qualification.
