From Buddha to Bataille, Eros to Wilde, Marx to MTV, Freud to Cyborgs, desire is the Trickster who hides within the gardens of the sensuous and the market, that lurks behind the altars of passion, repression, and allure. Icon, fetish, logo, idol, brand, hot and cool, hand and skin, dream. Desire is the silver coin and golden bite - Orgasmic Magus, fantastic Wiccan, creative might, sleepless night, whisper to the ear, high crack in the ice, leakage, fear, protoplasmic tear. Desire is an iceberg floating in a melting sea of oil and greed, tectonic tremor, shifting, changing, slipping, restless void and fill. It is opaque obsession, obscure temptation, nostalgia, memory scent, engine of commerce and war, longing for love and for peace. This course investigates how the above "economies" of desire cut across the human condition through the global economies of consumption, pollution, technology, media, and the image. To understand these linkages we will use some of the tools of anthropology, philosophy, political economy and political ecology, sociology, psychology and neuroscience, looking at how they mix with environmental ethics, religious, psychic and material economies, and brain cartographies. The course, ultimately, tries to ask how to balance reptile and mammal with the neocortex, and their stranglehold on water and air, fire and earth, by inquiring what next beyond endless wants, shopping and waste, war, permanent hunger and need.
