And so it may be with our means of locomotion and intercommunion, and what depends on them.  The vast and unprecedented amount of capital, of social interest, of actual human intellect invested—­I may say locked up—­in these railroads, and telegraphs, and other triumphs of industry and science, will not enter into competition against themselves.  They will not set themselves free to seek new discoveries in directions which are often actually opposed to their own, always foreign to it.  If the money of thousands are locked up in these great works, the brains of hundreds of thousands, and of the very shrewdest too, are equally locked up therein likewise; and are to be subtracted from the gross material of social development, and added (without personal fault of their owners, who may be very good men) to the dead weight of vested selfishness, ignorance, and dislike of change.

Yes.  A Byzantine and stationary age is possible yet.  Perhaps we are now entering upon it; an age in which mankind shall be satisfied with the “triumphs of science,” and shall look merely to the greatest comfort (call it not happiness) of the greatest number; and like the debased Jews of old, “having found the life of their hand, be therewith content,” no matter in what mud-hole of slavery and superstition.

But one hope there is, and more than a hope—­one certainty, that however satisfied enlightened public opinion may become with the results of science, and the progress of the human race, there will be always a more enlightened private opinion or opinions, which will not be satisfied therewith at all; a few men of genius, a few children of light, it may be a few persecuted, and a few martyrs for new truths, who will wish the world not to rest and be thankful, but to be discontented with itself, ashamed of itself, striving and toiling upward, without present hope of gain, till it has reached that unknown goal which Bacon saw afar off, and like all other heroes, died in faith, not having received the promises, but seeking still a polity which has foundations, whose builder and maker is God.

These will be the men of science, whether physical or spiritual.  Not merely the men who utilise and apply that which is known (useful as they plainly are), but the men who themselves discover that which was unknown, and are generally deemed useless, if not hurtful, to their race.  They will keep the sacred lamp burning unobserved in quiet studies, while all the world is gazing only at the gaslights flaring in the street.  They will pass that lamp on from hand to hand, modestly, almost stealthily, till the day comes round again, when the obscure student shall be discovered once more to be, as he has always been, the strongest man on earth.  For they follow a mistress whose footsteps may often slip, yet never fall; for she walks forward on the eternal facts of Nature, which are the acted will of God.  A giantess she is; young indeed, but humble as yet:  cautious and modest beyond her years.  She is accused of trying to scale Olympus, by some who fancy that they have already scaled it themselves, and will, of course, brook no rival in their fancied monopoly of wisdom.
