in general, the term "bilge" refers to a person who is able to distinguish right from wrong, whose opinion is considered true, who is supported by sprituel-beings, who is virtuous, self-controlled, loyal and persuasive. When the term "bilge" is used for a leader, it means state-establesher, legislator and who raises life standarts. Simi- , larly, the term "bilge kagan" may be compared with Plato's term "king-philosopher"; therefore, it may be said that the term "bilge" precedes Farabi and İbn Sina's concepts like al-hakim, al-faylasuf.
