The Fold: Leibniz and the Baroque

I n this fascinating but sometimes baffling book, the reader engages with a series of conditionals like the following: "If [the psychiatrist] Clerimbault manifests a delirium, it is because he discovers the tiny hallucinatory perceptions of ether addicts in the folds of clothing" (p.38). "If Leibniz's principles [of identity and sufficient reason] appear to us as cries, it is because each one signals the presence of a class of beings that are themselves crying and draw attention to themselves by these cries ..... (p. 44). Deleuze's study is concerned with Leibniz and with leibnizianism; with the Baroque considered as a historical period and with the baroque considered as a persistent impulse in architecture, decoration, and in human thinking and system construction. Baroque and baroque are explorations, in his view, of curvilinearity, and Deleuze explores Leibniz's use of mathematical analogies from topology, projective geometry and the calculus. But his attention in the book is mainly fixed on two Leibnizian images. The first image is that of the two-storied house, typically represented in baroque painting by an angelic realm in the upper half of the picture hovering above the human realm. In Leibniz' s writings, this translates into the world of matter (a seething, frothing, turbulent, unconscious mass of tiny beings) and the world of intelligent, self-conscious spirits on the upper level. The second image is that of the fold, which appears in the pleats and draperies of Baroque costume, sculpture, and interior decoration, and which reappears in Leibniz's mind-as-folded curtain, in his enveloped organisms, preformed under folds, and in the continuum, from whose recesses ever more numbers or particles can be pulled out. In clothing, waves, the brain, pleats of all sorts, surface disappears into interior. Deconstruction! But is it philosophy? Yes! Though Deleuze pulls his comparison-objects out of every comer of contemporary French culture, they are never arbitrary, and the book is focused clearly on its subject. Here are three reasons to buy it and read it in addition to its charm: (1) It contains several valuable discussions of traditional problems in new terms: e.g., Leibniz's elusive notion offreedom, which Deleuze tries to explain in terms of the notion of "amplitude"; and the problem of why there are bodies at all-why a "separate" monadology is needed together with a theory of animated matter.
