Greeks had hit upon the idea of movable types--and it is little to the credit of the Invisible King that they did not--the onrush of barbarism and Byzantinism would not have been half so disastrous. And even through the Dark Ages the bias towards betterment is still perceptible, though its operation was terribly hampered. Then, at last, the sixteenth and seventeenth centuries took up the thread of progress where antiquity had dropped it. Science revived, and bade defiance to dogma. The garnering of knowledge began afresh; and true knowledge has this to distinguish it from pseudo-sciences like astrology, theology, and philately, that it is instinct with procreative vigour. Knowledge breeds knowledge with ever-increasing rapidity; and the result is that the past hundred years have seen additions to man's control over the powers of nature which outstrip the wildest imaginings of Eastern romance. When Mr. Gladstone first went to Rome in 1832, his "transportation" was no swifter and scarcely more comfortable than that of Caesar in the fifties before Christ. Today he could fly over the Matterhorn and Monte Rosa, and then cover the distance from Milan onwards at the rate of seventy miles an hour in a limousine as luxurious as an Empress's boudoir. We are piling up the knowledge which is power at an enormous rate--indeed rather too rapidly, since we have not yet the sense to discriminate between power for good and power for evil. But "burnt bairns dread the fire," and after the present awful experience, there is fair ground for hope that measures will be taken to provide strait-waistcoats for the criminal lunatics whose vanity and greed impel them to let loose the powers of destruction. Can any thinking man say that the world is quite the same to him since the invention of wireless telegraphy? True it is only one among the multitude of phenomena behind which the Veiled Being dissembles himself. But is it not a phenomenon of a new and perhaps an epoch-marking order? It may not make the veil more diaphanous, but it somehow suggests an alteration--perhaps a progressive alteration--in its texture. When we say we are sure of the fact of progress, the atheist comes down on us with the retort that we thereby confess ourselves naive and credulous optimists. As well say that when we express our confidence that the North Western Railway will carry us to Manchester, we thereby imply the belief that Manchester is the Earthly Paradise. It is quite possible--any one who is so minded may say it is quite probable--that progress means advance towards disillusion. What we are sure of is merely this: that life may be, and ought to be, a very different thing from what it now is, and that it is in our own power to make it so. We have not the least doubt that the generations which come after us will say:-- We will not cease from mortal strife, Nor shall the sword slip from our hand, Till we have built Jerusalem In England's green and pleasant land.
