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.
John MiltonYet hold it more humane, more heav'nly, first, By winning words to conquer willing hearts, And make persuasion do the work of fear.
John MiltonHe who freely magnifies what hath been nobly done, and fears not to declares as freely what might be done better, gives ye the best covenant of his fidelity.
John Milton
