the twilight of fable. The republic of Venice came next in antiquity. But the republic of Venice was modern when compared with the Papacy; and the republic of Venice is gone, and the Papacy remains. The Papacy remains, not in decay, not a mere antique, but full of life and youthful vigor. The Catholic Church is still sending forth to the farthest ends of the world missionaries as zealous as those who landed in Kent with Augustine, and still confronting hostile kings with the same spirit with which she confronted Attila. The number of her children is greater than in any former age. Her acquisitions in the New World have more than compensated for what she has lost in the Old. Her spiritual ascendency extends over the vast countries which lie between the plains of the Missouri and Cape Horn, countries which, a century hence, may not improbably contain a population as large as that which now inhabits Europe. The members of her communion are certainly not fewer than a hundred and fifty millions; and it will be difficult to show that all other Christian sects united amount to a hundred and twenty millions. Nor do we see any sign which indicates that the term of her long dominion is approaching. She saw the commencement of all the governments and of all the ecclesiastical establishments that now exist in the world; and we feel no assurance that she is not destined to see the end of them all. She was great and respected before the Saxon had set foot on Britain, before the Frank had passed the Rhine, when Grecian eloquence still flourished in Antioch, when idols were still worshipped in the temple of Mecca. And she may still exist in undiminished vigor when some traveller from New Zealand shall, in the midst of a vast solitude, take his stand on a broken arch of London Bridge to sketch the ruins of St. Paul's. We often hear it said that the world is constantly becoming more and more enlightened, and that this enlightening must be favorable to Protestantism and unfavorable to Catholicism. We wish that we could think so. But we see great reason to doubt whether this be a well-founded expectation. We see that during the last two hundred and fifty years the human mind has been in the highest degree active, that it has made great advances in every branch of natural philosophy, that it has produced innumerable inventions tending to promote the convenience of life, that medicine, surgery, chemistry, engineering, have been very greatly improved, that government, police, and law have been improved, though not to so great an extent as the physical sciences. But we see that, during these two hundred and fifty years, Protestantism has made no conquests worth speaking of. Nay, we believe that, as far as there has been a change, that change has, on the whole, been in favor of the Church of Rome. We cannot, therefore, feel confident that the progress of knowledge will necessarily be fatal to a system which has, to say the least, stood its ground in spite of the immense progress made by the human race in knowledge since the days of Queen Elizabeth. Indeed, the argument which we are considering seems to us to be founded on an entire mistake. There are branches of knowledge with respect to which the law of the human mind is progress. In mathematics, when once a proposition has been demonstrated, it is never afterwards contested. Every fresh story is as solid a basis for a new superstructure as the original...
