Ramón Llull, via Alchetron. The ribbon in his mouth says Lux mea est ipse dominus, “My light is the Lord himself”
There’s an exhibition at Barcelona’s CCCB called “The Thinking Machine: Ramon Llull and the ars combinatoria,” up through December 11. Including work by Arnold Schönberg, Athanasius Kircher, Giordano Bruno, Leibniz, Italo Calvino, John Cage, and Salvador Dalí, the show makes its case for the influence of the Catalan philosopher Ramón Llull (1232-1316, sometimes anglicized “Raymond Lully”), who might be credited with inventing the first computer, or its primitive ancestor.
I first became aware of Llull and his contraption in Jorge Luis Borges’ Selected Non-Fictions, which reprints “Ramón Llull’s Thinking Machine,” an article Borges wrote for El Hogar Magazine in 1937. Borges gives the most lucid description of the machine I’m aware of, starting with its simplest, two-dimensional form, a circle divided nine times:
It is a schema or diagram of the attributes of God. The letter A, at the center, signifies the Lord. Along the circumference, the letter B stands for goodness, C for greatness, D for eternity, E for power, F for wisdom, G for volition, H for virtue, I for truth, and K for glory. The nine letters are equidistant from the center, and each is joined to all the others by chords or diagonal lines. The first of these features means that all of these attributes are inherent; the second, that they are systematically interrelated in such a way as to affirm, with impeccable orthodoxy, that glory is eternal or that eternity is glorious; that power is true, glorious, good, great, eternal, powerful, wise, free and virtuous, or benevolently great, greatly eternal, eternally powerful, powerfully wise, wisely free, freely virtuous, virtuously truthful, etc., etc.
I want my readers to grasp the full magnitude of this etcetera. Suffice it to say that it embraces a number of combinations far greater than this page can record. The fact that they are all entirely futile—the fact that, for us, to say that glory is eternal is as rigorously null and void as to say that eternity is glorious—is of only secondary interest. This motionless diagram, with its nine capital letters distributed among nine compartments and linked by a star and some polygons, is already a thinking machine. It was natural for its inventor—a man, we must not forget, of the thirteenth century—to feed it with a subject matter that now strikes us as unrewarding. We now know that the concepts of goodness, greatness, wisdom, power, and glory are incapable of engendering an appreciable revelation. We (who are basically no less naive than Llull) would load the machine differently, no doubt with the words Entropy, Time, Electrons, Potential Energy, Fourth Dimension, Relativity, Protons, Einstein. Or with Surplus Value, Proletariat, Capitalism, Class Struggle, Dialectical Materialism, Engels.
Then, Borges moves on to the more elaborate version of Llull’s thinking machine—the one with three revolving disks, illustrated below:
If a mere circle subdivided into nine compartments can give rise to so many combinations, what wonders may we expect from three concentric, manually revolving disks made of wood or metal, each with fifteen or twenty compartments? This thought occurred to the remote Ramón Llull on his red and zenithal island of Mallorca, and he designed his guileless machine. The circumstances and objectives of this machine no longer interest us, but its guiding principle—the methodical application of chance to the resolution of a problem—still does.
Let us select a problem at random: the elucidation of the “true” color of a tiger. I give each of Llull’s letters the value of a color, I spin the disks, and I decipher that the capricious tiger is blue, yellow, black, white, green, purple, orange, and grey, or yellowishly blue, blackly blue, whitely blue, greenly blue, purplishly blue, bluely blue, etc. Adherents of [Llull’s] Ars magna remained undaunted in the face of this torrential ambiguity; they recommended the simultaneous deployment of many combinatory machines, which (according to them) would gradually orient and rectify themselves through “multiplications” and “eliminations.” For a long while, many people believed that the certain revelation of all the world’s enigmas lay in the patient manipulation of these disks.
