To the other points which Pelagius makes them urge who argue against original sin, I have already, I think, sufficiently and clearly replied in the two former books of my lengthy treatise. Now if my reply should seem to any persons to be brief or obscure, I beg their pardon, and request the favour of their coming to terms with those who perhaps censure my treatise, not for being too brief, but rather as being too long; whilst any who still do not understand the points which I cannot help thinking I have explained as clearly as the nature of the subject allowed me, shall certainly hear no blame or reproach from me for indifference, or want of understanding me. I would rather that they should pray God to give them intelligence.
