Elizabeth Grosz’s Chaos, Territory, Art (Ch. 1: “Cosmos, Territory, Architecture”)
Alphonso Lingis’ Dangerous Emotions (Chs. 1: “The Navel of the World” and 3 “Faces”).
Optional background:
1. Jonathan Culler’s “Performative Language,” and “Identity, Identification, and Subject” from Literary Theory: A Very Short Introduction (New York: Oxford University Press, 1997). Cathy Caruth’s “Traumatic Awakenings” in Andrew Parker and Eve Sedgwick (eds.) Performativity and Performance (London: Routledge, 1995)
2. A quick (but dense) example of Žižek’s (usually much more elaborate) take on Deleuze’s take on Lacan. Oh, and if this is your first exposure to Lacan, here’s a great overview of the “Symbolic, Imaginary, Real” system.
3. The Stanford Encyclopedia of Philosophy has a nice collaboratively written summary of the work of Giles Deleuze and Felix Guattari. Read sections 4.1 on What is Philosophy (Paris: Éditions de Minuit, 1991; trans. by H. Tomlinson and G. Burchell, New York: Columbia, 1994), for an acquaintance with the notions of science, art, and philosophy that inform Elizabeth Grosz core text above; 4.2 on A Thousand Plateaus offers crucial background on the Deleuzian/Guattarian notion of “planes of intensity” and “planes of immanence”; read section 5 if you’re interested.
