SOPHISM

Sophistes derived from the Greek Sophia, which means the policy or learning. The shopia develop expertise in the fields of poetry, seer, and in the end they believe in realistic sciences such as social sciences, economics, politics, arithmetic, music, etc.. This has increased the intellectual sophistication of the cities in athens.
