I.—GENERAL PROGRESS.
This of ours is a conceited century. In intense self-consciousness it exceeds any of its late predecessors. Its activity in externally directed thought is accompanied by an almost corresponding use of introverted reflection. Its inheritance, and the additions it has made, can make or will make thereto, supply an ever-present theme. It delights to stand back from its work, like the painter from his easel, to scan the effect of each new touch—to note what has been done and to measure what remains. It is a great living and breathing entity, informed with the concrete life of three generations of mankind the most alert and the most restless of all that have existed. This sensation of exceptional endowments is self-nourishing and ever-growing; and our little nook of time is coming to view all the paths of the past, broad or narrow, direct or interlacing, straight or obscure, as so many roads laid out and graded for the one purpose of leading straight to its gate. It sounds its own praises and celebrates itself at all opportunities. But with all this there is a wholesome recognition of responsibility. Nobility obliges, it is prompt to confess, and to act accordingly. It sees flaws in its regal diamonds, spots that still sully on its ermine; and is not slow to address itself to the duty of their removal.
If the century understands itself, it may be said likewise to understand the others better than they did themselves. It collects their respective autobiographies and their mutual criticisms. The real truths, half truths and delusions each has added to the accumulating common stock it sifts and weighs, mercilessly piling a dustheap beyond Mr. Boffin's wildest dreams, and rescuing, on the other hand, from the old wastebasket many discarded scraps of real but till now unacknowledged value. Busy in gathering stores of its own, it is able to find time for digesting those bequeathed to it, and for executing both tasks with a good deal of care. It brings skepticism to its aid in both, and subjects new and old conclusions to almost equally close analysis. Each new pebble it picks up upon the shore of the Newtonian ocean it holds up square and askew to the light, and cross-examines color, texture and form. Now and then, being but mortal after all, it chuckles too hastily over a brilliant find, but the blunder is not apt to wait long for correction. Just now it appears to be overhauling its accounts in the item of science, taking stock of its discoveries in that field, balancing bad against good, and determining profit and loss. Some once-promising entries have to undergo a black mark, while a few claims that were despaired of come to the fore. This proceeding is only preparatory, however, to a new departure on a bolder scale. Scientific progress knows only partial checks. Its movement is that of a force en échelon: one line may get into trouble and recoil, while the others and the general front continue to advance. Theory does not profess to be certainty. It is only tentative, and subject necessarily to frequent errors, for the elimination of which the severely skeptical spirit of the laws to which it is now held furnishes the best appliance....
