On Celestial Engines and the Perils of Singular Reliance

I confess that when this extraordinary dispatch was placed before me — purporting to arrive from the year 2026 — I experienced that peculiar vertigo which attends the collision of the plausible with the impossible. And yet, having spent no small portion of my faculties upon Mr. Babbage's Analytical Engine, I find myself less incredulous than perhaps I ought to be. That mankind should one day propel living souls beyond our atmosphere and into the celestial void — this is an aspiration I can entertain without violence to reason. The mathematics do not forbid it. Indeed, if one may compute the perturbations of planetary orbits, one may in principle compute the trajectory of a vessel flung heavenward by controlled combustion. The leap is one of engineering magnitude, not of kind. What arrests my attention most keenly, however, is not the voyage itself but the predicament described: a great national agency of philosophy and exploration finding itself dependent upon a single contractor for passage to a station suspended among the stars. Here I detect a pattern as old as statecraft — the danger of entrusting indispensable operations to one hand alone. That a second manufacturer falters in its certification whilst the first advances with apparent vigour is a tale that might have been told of rival locomotive firms in our own decade, though the stakes are rather more elevated, in every sense of the word. I am struck, too, by the mention of speculative financial valuation attending these endeavours. Even in 1843, I observe how the promise of machinery excites the markets beyond all proportion to demonstrated achievement. The railway mania that presently grips this nation teaches us that engines of genuine power attract parasitic enthusiasms which may, in their collapse, imperil the very enterprises they once inflated. And yet — let me speak plainly — I find the entire vision magnificent. Imagination is not the mere faculty of invention; it is the faculty that penetrates the unseen relations governing phenomena. Without it, Mr. Babbage's Engine is but brass and iron. With it, we may weave patterns of number into patterns of discovery, and perhaps one day patterns of starlight. I do not know whether this dispatch is prophecy or phantasy. But I note, with no small satisfaction, that the future still requires engines — and that engines still require those who understand what they may and may not do. The Analytical Engine operates upon number; it cannot originate. The same, I suspect, is true of celestial vessels. They carry us only so far as our comprehension permits.
