There is nothing wrong with Oedipus committing into searching who killed the

King Laius. Oedipus behave as the king and it was the best thing to do to show his

authority to his population. As story goes, the purpose to search the murder changes.

Oedipus ignoring each advises that warn him about risk to know the truth have gradually

become selfish. At the end, everything is uncovered, letting Oedipus be ruined. The

problem is the King losing his publicity and being so selfish.

I assume that the author Sophocles attempted to describe the essence of

philosophy by providing the symbolized character seeking the truth as philosophers do.

What the philosophers study about is to define us human being because philosophers

always mention that destination of study is nothing but studying ourselves. As Oedipus

change the purpose of an investigation to find the murders toward to find own birth, any

study categorized into philosophy will finally reach to ego’s advantage. Sophocles

referred to how silly people behave when he lacks publicity and be such selfish. In Greek

world, religions was directly related to morality of people. Sophocles was afraid of

people who are too involved in philosophy losing morality or publicity and eventually

individualistic, which would possibly spoil ancient Greek states.
     
     Oedipus was too involved in philosophy even though he was the king of the state.

Unless the person who was required the enormous publicity could lose the morality by

seeking the own foolish truth, ordinary people may not protect themselves from the

allurement. The conclusion is that Oedipus should accept advises and immediately stops

investigating the truth.
