48. There remain those branches of knowledge which pertain not to the bodily senses, but to the intellect, among which the science of reasoning and that of number are the chief. The science of reasoning is of very great service in searching into and unravelling all sorts of questions that come up in Scripture, only in the use of it we must guard against the love of wrangling, and the childish vanity of entrapping an adversary. For there are many of what are called sophisms, inferences in reasoning that are false, and yet so close an imitation of the true, as to deceive not only dull people, but clever men too, when they are not on their guard. For example, one man lays before another with whom he is talking, the proposition, "What I am, you are not." The other assents, for the proposition is in part true, the one man being cunning and the other simple. Then the first speaker adds: "I am a man;" and when the other has given his assent to this also, the first draws his conclusion: "Then you are not a man." Now at this sort of ensnaring arguments, Scripture, as I judge, expresses detestation in that place where it is said, "There is one that showeth wisdom in words, and is hated;" although, indeed, a style of speech which is not intended to entrap, but only aims at verbal ornamentation more than is consistent with seriousness of purpose, is also called sophistical.
