[Latin] nosce te ipsum [Notes] From Cicero, based on the Greek γνῶθι σεαυτόν (gnothi seauton), inscribed on the pronaos of the Temple of Apollo at Delphi, according to the Greek periegetic writer Pausanias (10.24.1). A non-traditional Latin rendering, temet nosce (thine own self know), is translated in The Matrix as "know thyself". [Translation] 
know thyself
