"Ghosts in the Machine" at the New Museum Ghosts in the Machine , at the New Museum, features some 140 works, including "Movie-Drome," a mix of projected films, slides and drawings on the walls of a hemispherical room, by the filmmaker Stan VanDerBeek. If "Ghosts in the Machine," an ambitious, multitasking, somewhat austere exhibition at the New Museum were itself a machine, it would have lots of moving parts, but not all of them would be performing with equal efficiency. Walking through this enormous show, which has been orchestrated by Massimiliano Gioni, the museum's associate director and head of exhibitions, and Gary Carrion-Murayari, its curator, can call to mind one of Marcel Duchamp's lesser-known quips. In a 1963 interview in Vogue, cited in Calvin Tomkins's 1996 biography of him, Duchamp claimed that the aesthetic life span of an art object - what he called its "emanation" - "doesn't last more than 20 or 30 years." Referring to his most famous painting, the 1912 "Nude Descending a Staircase, No. 2," he added, "I mean, for example that my "Nude" is dead, completely dead." Mr. Tomkins suggests that his subject was half-joking, but only half. The New Museum show repeatedly proves Duchamp about half right. As smart and thought stirring as this exhibition is, it is also a little short on living, breathing artworks, and slightly overloaded with rather stale ones and other objects and diagrams that, altogether, function primarily as interesting period pieces or historical artifacts. In the catalog Mr. Gioni writes that the show was not conceived as "a classic historical survey" but as a "cabinet of curiosities." Casting a wide net and moving quickly and a little capriciously across time and national boundaries, it sets out to examine some of the artistic reflections of our machine-haunted, technology-dependent era, especially in the second half of the last century. It is far less interested in bringing together established masterpieces than in using unfamiliar artworks to shed light on a machine-infested terrain that is as social and psychological as it is visual. The exhibition contains just enough powerful art - including some surprising resurrections - to pull it off. The show's mixture of marginal art movements and neglected objects ranges from 1960s Op Art paintings by Bridget Riley and Julian Stanczak to a reconstruction of Wilhelm Reich's notorious Orgone Energy Accumulator from 1940; sitting in it was supposed to unblock the flow of life energy. There are constant swings among decades, allowing you, for example, in the museum's lobby, to peruse "The Way Things Go," the brilliantly witty 1987 video of chain reactions involving ordinary objects by Peter Fischli and David Weiss that is often likened to the creations of Rube Goldberg, and then go upstairs and study some drawings from the 1930s by Goldberg himself, sharpening your appreciation of the analogy. There are works by machine-obsessed outsider artists, healers and mental patients, including a series of suspended wire constructions by the self-taught American sculptor Emery Blagdon (1907-86), who thought they could cure illness. One of the show's few dips into the premodern era is an 1810 engraving based on the delusional drawing by James Tilly Matthews, an Englishman who is generally considered the first person to receive a diagnosis of schizophrenia, that depicts his domination by a machine he called the Air Loom. A majority of the show's roughly 140 artworks, diagrams and related objects date from the mid 1950s to the mid-"70s - the halcyon years of postwar art and, not coincidentally, the beginning of the technological blossoming in which we currently find ourselves. The machine theme means that the show largely avoids the period's dominant styles - especially Pop and Minimalism - favoring the more science- and technology-focused tendencies that they overrode or shunted aside. These include not only Op Art but also Kinetic art and what might be called op-kinetic hybrids, pursued in particular by little-known Italian artists. There are also several computer-generated films and a cache of wan computer-made drawings. This show repeatedly reminds you that every major scientific advance has artistic repercussions, artists who see it as the basis for something new and revolutionary, a way to go beyond conventional notions of touch, authorship and personal expression (even though it sometimes seems that the baby has been discarded with the bath water). "Ghosts in the Machine" continues through Sept. 30 at the New Museum, 235 Bowery at Prince Street, Lower East Side; (212) 219-1222, newmuseum.org.
