Against Onetor I

You on your part hold that in both private and public matters the torture is the most certain of all methods of proof, and when slaves and freemen are both available, and the truth of a matter is to be sought out, you make no use of the testimony of the freemen, but seek to ascertain the truth by torturing the slaves; and very properly, men of the jury. For of witnesses who have given testimony there have been some ere now who have been thought not to tell the truth; but of slaves put to the torture no one has ever been convicted of giving false testimony.
