I've been thinking about Donna Haraway's cyborg theories and how she tries to propose a fluidity beyond the constraint and absolutism of unquestionable binaries...I immediately think of the emphasis of male/female, dark/light (this could be coded as racial in a more recent historical context), sun/moon, material/ideal, biological/synthetic, etc. Why and how was this significant in the development of various cultures, such as Western European culture, Meso-American culture, South Asian culture, etc. I feel that learning about the genesis and necessity of binaries within various cultures will aid me in understanding the fabric of present Western social order, and the relation between people, their environment, and each other.
