lit. signifies "without understanding" (a, negative, nous, "mind"); hence, "folly," or, rather, "senselessness," 2 Timothy 3:9; in Luke 6:11 it denotes violent or mad rage, "madness." See MADNESS. Cp. anoetos, "foolish."
Note: For aphrosune, rendered "folly" in 2 Corinthians 11:1 , AV, see FOOLISHNESS (RV).
