"What then, is correctness of speech but the maintenance of the practice of others, as established by the authority of ancient speakers? But the weaker men are, the more they are troubled by such matters. Their weakness stems from a desire to appear learned, not with a knowledge of things, by which we are edified, but with a knowledge of signs, by which it is difficult not to be puffed up in some way; even a knowledge of things often makes people boastful, unless their necks are held down by the Lord's yoke."
