Rightly then, Plato, in the Epistles, treating of God, says: “We must speak in enigmas; that should the tablet come by any mischance on its leaves either by sea or land, he who reads may remain ignorant.” For the God of the universe, who is above all speech, all conception, all thought, can never be committed to writing, being inexpressible even by His own power. And this too Plato showed, by saying: “Considering, then, these things, take care lest some time or other you repent on account of the present things, departing in a manner unworthy. The greatest safeguard is not to write, but learn; for it is utterly impossible that what is written will not vanish.”
