In Influx & Efflux Jane Bennett pursues a theme opened but not pursued in her influential book Vibrant Matter. She explores the question of human agency amidst a world teeming with powerful nonhuman influences. "Influx and efflux"--borrowed from Whitman's "Song of Myself"--refers to everyday movements whereby outside influences enter bodies, infuse and confuse their organization, and then exit, themselves having been transformed into something new. How to describe the effort or human agency involved in that process? What kinds of "I" and "we" can live well and act effectively in a world of so many other lively materialities? Drawing upon Whitman, Thoreau, Caillois, Whitehead, and other poetic writers, Bennett links a non-anthropocentric model of self to a democratic pluralism and also to a syntax and style of writing appropriate to the entangled world in which we live. She wades into those uncanny processes by which we "write up" influences that have pervaded us, both drawing sustenance from them and altering them as we do so. This is a engaging book in which the writer enacts the very processes she delineates.
