Institutio Oratoria

A like situation arises in the case of evidence extracted by torture: one party will style torture an infallible method of discovering the truth, while the other will allege that it also often results in false confessions, since with some their capacity of endurance makes lying an easy thing, while with others weakness makes it a necessity. It is hardly worth my while to say more on the subject, as the speeches both of ancient and modern orators are full of this topic.
