phront-, phorntid-; phronemo-, phron-
(Greek: thought, care, attention; think, thinking, contemplation)
The Greeks had a word, phrontisterion, to indicate a place for thought and study or a "thinking-shop" (think tank?). Aristophanes (c. 450-c. 380 B.C.), was an Athenian dramatist who is known to have written more than 40 comedies that gave satiric expression to his strong, conservative prejudices against certain trends and personalities in the Athens of his day. It was this Aristophanes who used the Greek equivalent of phrontistery to ridicule the school of Socrates.
The Greek noun was derived from phrontistes (philosopher, profound thinker, one with intellectual pretensions) from the verb phrontizein (to reflect), based on phrontis (thought, reflection). The word phrontist applies to a "deep thinker," a "person involved in study, reflection, meditation," and it, too, in its Greek form, was applied ironically by Aristophanes to Socrates himself.
