"I find nothing, my dear pupil," he said, "in the Christian Church, very old, concerning this doctrine—for that author who goes by the name of Dionysius the Areopagite is of far later date—but I will discover to you some mysteries concerning it, which, so far as I know, have never been brought to light by any man. I find the germ of this doctrine in those fragments of metaphysics which go under Theophrastus, his name; who was a disciple of Aristotle, and succeeded him in his school; and was an excellent philosopher, certainly, by the works by him which remain to this day. Here he says that the understanding joined to the body, can do nothing without the senses, which help it as far as they can to distinguish sensible things from their first causes, but that all knowledge and contemplation of the first causes must be by very touching and feeling of the mind and soul; which knowledge, thus gained, is not liable to error. Synesius, a man well known amongst scholars, being vexed that this new divinity began in his day to be in request amongst Christians; and some illiterate monks and others taking advantage of it to magnify ignorance, to bring themselves into repute—Synesius, I say, wrote that exquisite treatise, which he inscribed ’Dio,’ to prove the necessity of human learning and philosophy to all who will contemplate high things with sobriety and good success. ’God forbid,’ he says, ’that we should think that if God dwell in us, He should dwell in any other part of us than that which is rational, which is His own proper temple.’ "Now whether the writings of some ancient and later Platonists, Greeks and Arabs, Heathens and Mahometans be a sufficient ground and warrant for them that profess to ascribe more to the Scriptures, by which sobriety of sense is so much commended unto us, than to the opinions of heathen philosophers, I leave you to consider."
