Perhaps some may ask, “How is it, then, that reasoning, if it rules the emotions, isn’t also master of forgetfulness and ignorance?” They attempt a ridiculous argument. For reasoning does not rule over its own emotions, but over those that are contrary to justice, courage, temperance, and self-control; and yet over these, so as to withstand, without destroying them.
