11. As the internal acknowledgment of truth is faith, and as faith and truth are a one (as was said above, n. 2, 4-6), it follows that an external acknowledgment without an internal one is not faith, and also that a persuasion of what is false is not faith. An external acknowledgment without an internal one is a faith in what is unknown, and a faith in what is unknown is mere memory-knowledge [scientia], which if confirmed becomes persuasion. They who are in such knowledge and persuasion think a thing true because somebody has said so, or they think it is true from their having confirmed it; and yet what is false can be confirmed just as well as what is true, and sometimes better. To think a thing true from having confirmed it is to think that something another says is true, and then to confirm it without previous examination.
