"The exposition will take up in turn the following constitutive features of the postmodern: a new depthlessness, which finds its prolongation both in contemporary ‘theory’ and in a whole new culture of the image or the simulacrum; a consequent weakening of historicity, both in our relationship to public History and in the new forms of our private temporality, whose ‘schizophrenic’ structure (following Lacan) will determine new types of syntax or syntagmatic relationships in the more temporal arts; a whole new type of emotional ground tone--what I will call ‘intensities’--which can best be grasped by a return to older theories of the sublime; the deep constitutive relationships of all this to a whole new technology, which is itself a figure for a whole new economic world system; and, after a brief account of postmodernist mutations in the lived experience of built space itself, some reflections on the mission of political art in the bewildering new world space of late or multinational capital."
