The thrust of Kleist’s text against this fusion of motion, subjectivity, and grace—against the core convictions of Weimar Classicism—must have been easily detectable for readers in 1810. Herr C.’s argument that inhuman marionettes exhibit more grace in their motions than human dancers, that, in fact, every instant of reflection prevents gracefulness, aims straight at the center of Schiller’s (and Goethe’s) attempt to bridge the chasm between body and mind, to install aesthetics above mechanics. At the same time, however, Herr C.’s quest for grace in motion reintroduces into natural philosophy the very theological parameters that Newton and the Newtonians had sought to eliminate. When the two interlocutors equate the loss of grace with the expulsion from paradise, they shift the attention from the moral to the anagogical sense of the concept. In its theological context, grace in motion—Grazie or Anmut—is the sign of paradisiacal wholeness, an embodied reminder of the innocence that was shattered irrevocably by the desire for knowledge. Weimar Classicism, cheerfully proclaiming its own paganism, held that paradise was just a mythological name for a historical formation, namely ancient Greece, that its loss was the result not of sin but of a history of decadence decisively shaped by the Christian Church, and that regaining paradise was, at least in principle, possible through a reawakening of the aesthetic sensibilities of antiquity, such as the moral feeling expressed in graceful motion. The notion of Bildung, so often evoked in the context of nineteenth-century German pedagogy, expressed this hope for an individual and secular recuperation of grace.10 Kleist’s Herr C. explores a radically different avenue to the restitution of grace: rather than promoting aesthetic education, he speculates that the return to grace will come as the result of a complete dehumanization and mechanization of motion.
This hope in the redemptive power of mechanical motion, then, was a broadside against Weimar Classicism, which, championed by Wilhelm von Humboldt and his Bildungs-reforms, had arrived in the Prussian capital just when Kleist published his short text. But the essay does more than polemicize, and what it does in addition is what makes it so interesting for our understanding of the future of mechanisms and their relations to culture and aesthetics in the nineteenth century—a future that is embodied in the cylinder and its kinematic properties. For unlike Romantic writers like E. T. A. Hoffmann or Mary Shelley, Kleist does not focus on the origin of motion or life in the puppets, nor does he marvel at their mimetic and illusory power. He does not mention the automata that delighted the eighteenth century before they began to haunt early nineteenth-century literature with their imitation of human consciousness and affectivity: he is solely interested in the spectacle of their motion.11 In the terms of nineteenth-century engineering, he focuses on marionettes neither as motors nor as tools but as transmissions. Discovering generalities in the transmission of motion is the purpose of nineteenth-century kinematics, a discipline as obscured by the awe of motors and the anxiety over mechanized tools as is the understanding of Kleist’s text by the biography of its author and the speculations about its programmatic aim.12 The genealogy of kinematics as an independent discipline is the subject of the next chapter.
It is true that the focus on kinematics in Kleist’s text is hidden behind what seem to be traditional hermeneutic and moral concerns. When asked whether making marionettes dance requires artistry on the part of the puppeteer, Herr C. claims that there is a “center of gravity” in every motion and that the line traced by this center is identical with “the way of the soul of the dancer.”13 To perfect the dance, then, the puppeteer—Kleist calls him “the machinist”—must place himself in the gravitational center of the marionette. This hermeneutic imperative of empathy is draped in mathematical language: the lines of motion, C. says, are either straight or of computable curvature, and the fingers of the puppeteer and the motion of the puppets are related “rather like numbers to their logarithms or the asymptote to the hyperbola.”14 But this second-order grace is achieved by a sleight of hand. As Kleist—who once divided people into those who understand metaphors and those who understand formulas—knew very well, mathematical metaphors, conjoining algebraic precision and the vagueness of the “rather like” (etwa wie), are inherently contradictory. As failed metaphors—catachreses—such figures of speech at the same time open and attempt to cover over a conceptual gap.15 In Herr C.’s case, this gap appears earlier in his statement that every motion has a gravitational center. Within the basic parameters of Newtonian physics, only individual bodies, not motions, have a center of gravity: it is the imaginary, non-extended point in which, for the purpose of calculation, all of a body’s mass is concentrated.16 The mathematization of motion in Newton’s rational mechanics—and with it the possibility of attributing grace to unforced motion—is based on the assumption that bodies can at the same time be treated as nonextended points that trace out curves in the Cartesian coordinate system and as massive atoms that are subject to the law of inertia. This latter law—Newton’s first law of motion—guarantees the continuity of motion; the geometrical inscription, on the other hand, allows for the calculation of its form. “Gravitational center of motion,” then, is the catachresis that reopens what historians of science call Newton’s great synthesis—his ability to treat discrete, massive bodies like continuous geometric shapes.17 In its attempt to cover up, the phrase brings attention to the abyss underneath the signal achievement of rational mechanics, the law of universal gravitation, by means of which the motion of physical entities is inscribed into the reversible and predictable grid of geometry.
Any endeavor to attack Newton’s mechanics frontally would be quixotic, given its explanatory success and its consolidation and empirical verification throughout the eighteenth and the early nineteenth centuries. But the bulk of that success—for example, the prediction of the return of Halley’s comet in 1758—was based on the motion of bodies so distant in a space so vast that indeed they could be treated as imaginary point masses. But what explanatory and predictive power do the laws of motion have for bodies moving close at hand—for bodies that can exhibit grace to human eyes? There is, of course, the anecdote of the falling apple at Woolsthorpe that the Newtonians kept reciting to underscore the universality of gravitation; but aside from ballistics experts, who would routinely experience the free fall of objects, let only find their translational motion graceful? What can Newton’s laws say about objects that do not simply fall but move nonetheless, such as wagon wheels, water pumps, pendulum clocks?18
This is the point of Herr C.’s fascination with, and critique of, marionettes. In a double sense he interprets them as pendulums: first, because the puppet follows the hand of the “machinist” with the lag of a string pendulum such that the straight-line motion of the hand is translated into the lagging curve of the logarithmic or hyperbolic function; second, because the limbs of each individual puppet, “which are only pendulums,” are not tied to “myriads” of strings and therefore follow the “gravitational center of the motion” in the puppet with a hesitation that inevitably results in “curves.” For marionettes as pendulums, the law of gravity is literally suspended—they are “antigrav,” as Kleist says—but the law of inertial motion persists. That persistence, and the lag that results from it, is precisely the reason for the marionette’s imperfection: it grants an abode for the “last fraction of human volition”—later in the essay it is called “affectation” (Ziererei)—that threatens to interrupt the grace of motion. The only way to overcome this danger is to eliminate the effects of inertia as well, and that is exactly what Herr
