XL. ARGUMENT: THEN CAECILIUS EXCLAIMS THAT HE IS VANQUISHED BY OCTAVIUS; AND THAT, BEING NOW CONQUEROR OVER ERROR, HE PROFESSES THE CHRISTIAN RELIGION. HE POST PONES, HOWEVER, TILL THE MORROW HIS TRAINING IN THE FULLER BELIEF OF ITS MYSTERIES.

 While, therefore, I was silently turning over these things in my own 'mind, Caecilius broke forth: "I congratulate as well my Octavius as myself, as much as possible on that tranquillity in which we live, and I do not wait for the decision. Even thus we have conquered: not unjustly do I assume to myself the victory. For even as he is my conqueror, so I am triumphant over error. Therefore, in what belongs to the substance of the question, I both confess concerning providence, and I yield to God; and I agree concerning the sincerity of the way of life which is now mine. Yet even still some things remain in my mind, not as resisting the truth, but as necessary to a perfect training of which on the morrow, as the sun is already sloping to his setting, we shall inquire at length in a more fitting and ready manner."
