(Concept of plato on justice)

Plato lived during the time when democracy in Athens was going down.
According to Plato, Justice is the only remedy to save the state. Justice is part of
the State. Justice is inseparable from the state. Justice resides in the state.
Justice means complete virtue. It means complete goodness. Justice consists of
wisdom, courage, and appetite. It is the true condition of the individual and the
state.
Platonic concept of Justice was not concerned with individual rights. It had
nothing to do with the system of law or courts also. It was a kind of moral
principles for the individual and the state. It said that none should interfere in
the affairs of others. Each person should mind only his own job. So there should
be functional specialization in the State.

There are two dimensions for Justice. One is the individual dimension and
the other is the social dimension. At the individual level, justice means having
the true vocation5 in life. That means, a person of appetite should become a
worker. A person of courage should become a soldier. A person of wisdom and
philosophy should become a philosopher. After that each person should stick to
his station6 in life. It means specialization of function.

From the point of the society, justice means the division of the society into
three classes. These classes represent the elements of reason, spirit and appetite.
Each class must mind its own job. They should not handle the function of the
other classes. This specialization leads to efficiency.

There is another dimension also for Platonic concept of Justice. The two
upper classes of Philosophers and Soldiers cannot have personal family and
personal family life. They must mind only the affairs of the state. They have no
time to mind family matters.
So friend this is all about the concept of plato on justice.
