If, then, any reader shall say, This is not well said, because I do not understand it; such a one finds fault with my language . . . : and it might perhaps in very truth have been put more clearly; yet no man ever so spoke as to be understood in all things by all men. Let him, therefore, who finds this fault in my discourse, see whether he can understand other men who have handled similar subjects and questions, when he does not understand me: and if he can, let him put down my book, or even, if he pleases, throw it away; and let him spend labor and time rather on those whom he understands. Yet let him not think on that account that I ought to have been silent, because I have not been able to express myself so smoothly and clearly to him as those do whom he understands. For neither do all things, which all men have written come into the hands of all. And possibly some, who are not capable of understanding even these our writings, may not find those more lucid works, and may meet with ours only. And therefore it is useful that many persons should write many books, differing in style but not in faith, concerning even the same questions, that the matter itself may reach the greatest number -- some in one way, some in another. But if he who complains that he has not understood these things never has been able to comprehend any careful and exact reasonings at all upon such subjects, let him in that case deal with himself by resolution and study, that he may know better; not with me by qaurrellings and wranglings, that I my hold my peace.
Let him, again, who says, when he reads my book, Certainly I understand what is said, but it is not true, assert, if he pleases, his own opinion, and refute mine if he is able. And if he do this with charity and truth, and take the pains to make it known to me (if I am still alive), I shall then receive the most abundent fruit of this my labour. And if he cannot inform myself, most willing and glad should I be that he should inform those whom he can.
