There is no learned man but will confess be hath much profited by reading controversies,--his senses awakened, his judgment sharpened, and the truth which he holds firmly established. If then it be profitable for him to read, why should it not at least be tolerable and free for his adversary to write? In logic they teach that contraries laid together, more evidently appear; it follows then, that all controversy being permitted, falsehood will appear more false, and truth the more true; which must needs conduce much to the general confirmation of an implicit truth.
