Under such circumstances the argument of Mr. Newman--judiciously compressed into a few sentences--appears to me even ludicrous. How different the course which Gibbon pursues! What a pity that the great historian did not perceive that this statement would have led him equally well to his desired end; that so brief a demonstration would suffice to account for that unmanageable phenomenon, the rapid progress and ultimate triumph of Christianity! He, on the contrary, seems to have read history with very different eyes; and yet I suppose no man will question either his learning or his sagacity. He finds himself obliged to admit the conspicuous advance which the Gospel had made before Constantine's accession, and employs every nerve to invent sufficient natural causes to account for it. What a facile task would he have had of it, if he had but bethought him that Christianity, instead of having been to an enormous extent successful was, in fact, waiting, in comparative failure, the triumphant aid of a military conqueror! He might then have dispensed with the celebrated chapter, and substituted for it the two pregnant sentences by which Mr. Newmen has, in effect, declared it superfluous. ____ August 7. Three days ago (the evening before my return home) I managed to prevail upon myself to have a close and formal discussion with Harrington on the subject of his scepticism. We had a regular fight, which lasted till midnight, and beyond. A good deal of it was (in a double sense, perhaps) a nuktomachia. As I had no one to jot down short-hand notes of our controversy,--perhaps it is as well for me and for truth that there was none,--it is impossible that I should do more than give you a succinct summary of its course. But its principal topics are too indelibly impressed on my memory to leave me in doubt about general accuracy. I hardly know what led to it; I believe, however, it was an observation he made on the different fates of metaphysical and physical science,--the last all progress, and the first perpetual uncertainty. He had been reading a remark of some philosopher who attributed this difference to the more substantial incentives offered to the cultivation of the physical sciences. "So that," said he, "they are, it seems, what our German friends would call 'Brodwissenschaften'! Not the brain, as some idly suppose, but the stomach, is the true organon of discovery, and if the metaphysician could but be punctually assured of his dinner (which has not always been the case), or at all events of a fortune, we should soon have the true theories of the Sublime and Beautiful,--of Ethics,--of the Infinite,--of the Absolute,--of Mind and Matter,--of Liberty and Necessity; whereas I think we should only have a multiplication of doubtful theories."
