СКАЧАТЬ mummy’s return was under the effects of the technique and not under supernatural conditions. The comparison of the two texts shows very divergent cultural and literary instrumentalizations of galvanization. While in the first, Poe relates the fictional conditions of reanimation; in the second, under the guise of mocking traditional fears, he takes the experience of the tortured to the absurd by taking as his object a mummy several millennia old. Poe’s reference to electricity corresponds to a long reflection on the unity of the laws of physics in the universe, culminating in Eureka [POE 48], an essay dedicated to Alexander von Humboldt. Body and soul of the universe, electricity allows us to understand nature in its totality, material and spiritual, to which we must relate the phenomena of vitality and consciousness:

      The cosmos was a vast electrical machine that could be understood and manipulated in much the same way as they understood and manipulated the electrical machines and artefacts with which they plied their trade. Human bodies were part of the electrical universe too. [RHY 02, p. 102]

      One reason why electrical engineers saw electrotherapeutics as an area where their own expertise was relevant was because they recognized the electrical body as being made up of the same kind of components, organized in the same kind of system as that on which they plied their trade. [RHY 02, p. 106]

      And it chanced that the direction of my scientific studies, which led wholly toward the mystic and the transcendental, re-acted and shed a strong light on this consciousness of the perennial war among my members. With every day, and from both sides of my intelligence, the moral and the intellectual, I thus drew steadily nearer to that truth, by whose partial discovery I have been doomed to such a dreadful shipwreck: that man is not truly one, but truly two. [STE 86, p. 75]

      This shift in the applications of these techniques cannot be detached from the organicist and materialist movement that integrates the mental faculties within the brain structures.

      Galvani had already spoken about neuro-electric fluid [GAL 53, p. 64] and attributed the genesis of animal electricity to the brain. Correlate to this the fact that the nervous structure was thought of in terms of wires for the nerves and voltaic pile for the brain organ. At the same time, the work of Ledru and abbé Sans on the links between artificial electricity and nervous diseases put forward the latter to be treated by the applications of electric fluid. Thus, at the time when electrotherapy was developing, the 19th Century was marked by an imaginary control by electricity of mores and behaviors considered harmful. If humans were beings in which matter generated consciousness, they seemed to be inhabited by a beast that sometimes pushed them to adopt harmful societal behaviors. On the literary side, we find this idea in Stevenson’s novel (1850–1894) or in The Beast in Man where Zola (1840–1902) [ZOL 85] stages the archetype of the mad murderer. This idea also developed in the imagining of galvanic doctors who, realizing the complexity of the links between the brain and consciousness, conceived these therapies as the guarantors of a certain moral security. Electricity then became a tool for the standardization of the individual, inherited from the research of Delgado or Heath in the mid-20th Century:

      There was a division between the idea of reducing the vital functions of a body to that of controlling the subject and his behaviors. A conceptual division between a medicine marked by the Cartesian dualism of the animal machine, then by the materialism of the 18th Century, and a holistic medicine where faculties and consciousness were integrated into the human machine. Yet these two approaches complemented each other. From the beginning of the 19th Century, neuroanatomical research was looking for Galvani’s neuro-electric fluid within the human brain, in order to record it and correlate it with the expression of mental faculties. In 1808, Malacarne was between a post-mortem approach of the brain organ to the idea of acting on its electricity. The analogy of the electrical machine to organic structures extended to the nervous system:

      Are not brains, nervous ganglions, and nerves, which are evidently the seat of vital action, in the identities we call animal, real electrical machines; similar in principle, as they are similar in substance and in structure, to the electrical discharging apparatus of the gymnotus and torpedo, which consist of large brain-like ganglions connected with the spinal cord? [MAC 31, p. 94 in RHY 98, p. 131]

      Thus, Malacarne published a text entitled “Conoscendo dalla organizzazione del cervelletto in ispezie, e forse anche da più attento esame del cervello e dalla midolla spinale che queste viscere formano qualche cosa di somigliante alla colonna galvanica del Volta” [MAL 08, pp. 122–130]. Probably the first localizer of the faculties within the cerebral organ, his research was marked among the scholars of the 19th Century [CHE 16].
