Socrates was interested in the knowledge of logical thinking (reason), especially in the field of ethics (good and evil). He urged fellow townspeople to think (critically) for themselves (about themselves, their gods and values) and not rely on the judgment of others. It was his habit to question everything. For example, he stated, “The unexamined life is not worth living” and “I know that I know nothing.” Socrates is described as someone who spoke critically about democracy. Not because he was in favor of a dictatorship, but because he wondered if everyone was thinking critically enough or was educated enough to vote or to run a country.
