If we stop to think for a second, there is nothing more extravagant than a ghost-detecting machine ––An artifice to “perceive” the incorporeal and the timeless: a machine that feels. If all the faith we have deposited in Physics and manufactured technology has increased our faith in metaphysics and spirits, then we are before one of the greatest and most recreational paradoxes.Ever since the first ghost communication device was invented, and we were supposedly able to establish communication with “the great beyond”, hundreds of thousands of mediums emerged alongside the popular Spiritist movement which, in few words, responds to the belief that souls continue to exist after death and that it is possible to talk to them. When in 19th century they proliferated, mediums made use of these charming artifacts to facilitate their connection with the dead and endorse the practice of spirit communication.

These devices had the ability of excreting a substance called “ectoplasm,” and they could also give a voice to the clients’ closely related defunct. All this began when the Western world was developing more and more scientific discoveries, like the theory of evolution, which weakened the existence of God. People experienced a crisis of faith and at the same time they invested themselves in ghost stories. Spiritism was a profound answer to the anxieties about God and whether there was life after death. If you could prove that the latter existed, the entire game changed ––The communication with the dead was seen as an inscrutable proof of the existence of God.

Years before the ouija board became an international obsession, spiritists from the Victorian Age were thoroughly amused by the famous planchettes: small heart-shaped boxes that would scribble messages supposedly dictated by the spirits of the dead. Planchettes owe a great deal of their popularity to the flirtatious and potentially sexual dynamic they allowed among their users. Men and women would sit in close contact, often in half-light and with their knees grazing, with their hands intimately touching the board as they wrote messages dictated by spirits.

In the meantime, other artifacts would fleetingly emerge before they became lost in darkness. The so-called “dial plate”, in which a clock-like plate intervened between the two realms, was one of them: when a medium manipulated the machine, the hands pointed at letters and formed specific messages. Another fascinating artifact was the so-called Psychograph, or Apparatus of Indicating a Person’s Thoughts. This complicated machine worked with a series of leverages and discs that the users manipulated to spell out the words of ghosts. It was nothing short of the first spiritist artifact to be patented in the world.

Like these, there were dozens of other versions (the Spiritscope, the Materialization Chamber, the Spirit Trumpet, the Cablegraph, or Spiritist Photography), but, of course, none of them lasted as long as the ouija board. This is the most prominent instrument that remains from that period, and today still makes people curl over with fear. It is likely that the demonic connotation of the ouija board can be traced back to that brief scene in The Exorcist when the young girl is talking to Captain Howdy on the board before she becomes possessed.

Today, however, when we talk about ghost-detecting machines we mean all sorts of virtual interfaces and apps that recreate ouija boards but go well beyond. There are spirit detectors, infrared cameras, electromagnetic field detectors, ghost radars and many other applications that can measure paranormal activity. They all carry out one fundamental function: they help us tell stories. Ghost stories of course.

The paradox of the “perceiving machine” is thus an ally in our own ontological need to tell stories, and in our metaphysical need to translate what lies beyond. In addition to being a dramatic resource to solve situations unexpectedly, the Latin phrase Deus ex machina, which meansGod from the machine”, eloquently summarizes the extravagance of Spiritism. It is a narrative resource but it is also a metaphysical one. We invented the machine to reconcile two worlds, to serve as the best of mediums, and to have the incorporeal and the improbable be mechanized before us, who believe more in that technological “natural inherence” than in our own intuitive capacity. The real mystery is not whether machines feel, but whether humans do.
