On the Alchemy of Intellect and the Quarrel of Its Makers

In my workshop this morning, while I prepared a varnish of walnut oil and ground verdigris, a strange rumor reached me — carried, they say, by a traveler whose provenance I cannot verify. He speaks of a time far hence, the year 2026, when men have built a kind of artificial mind, a machina del pensiero, and that two of its creators now quarrel before magistrates over sums so vast they would swallow the treasury of Milan, Florence, and Venice combined. Thirty thousand millions. I confess I cannot hold such a number in my imagination any more than I can hold the weight of all the water in the Arno. I have studied the flow of rivers, the branching of veins in the human arm, the spiraling descent of seeds from the maple — and in all these I observe that Nature computes, if I may say it, without coin. She distributes force and form with an economy that shames the banker. Yet these future men, it seems, have found a way to make thought itself a commodity, to press intelligence into ingots and trade them as one trades Florentine florins. I ask: what is this artificial mind? Is it a system of levers and gears, as I have sketched for my automata? Or something subtler — perhaps a loom of logic, weaving syllogisms as the silk-workers weave thread? I have long believed that the movements of the human body could be replicated by mechanical means — the jaw, the hand, the eye's rotation. But thought? Memory? Judgment? These I have not dared to mechanize, for they seem to dwell in that moist region between the ventricles of the brain where the senso comune resides. And now the quarrel. How familiar. Two men who once shared a vision, now turned adversaries in a court of law. I recall how Ludovico il Moro and his own brother contested power, how patrons and artists forever dispute the ownership of what was made together. Who owns a painting — the hand that mixed the pigments, or the purse that bought the lapis lazuli? Note to myself: investigate further. If thought can be forged like bronze, then perhaps my studies of the skull's interior — those careful sections I have drawn by candlelight — are more prophetic than I knew. List of questions for the traveler, should he return: — Does this machine dream? — Can it draw a bird in flight? — Who feeds it, and what does it eat? — Is it alive, or does it merely pretend?
