One definition of simultaneity differs from another because events that are simultaneous for one definition occur successively for another. What may be a simultaneity projection of a moving segment for one definition is a "focal-plane shutter photograph" for another.
Polyphonic painting is superior to music in that there, the time element becomes a spatial element. The notion of simultaneity stands out even more richly.Paul Klee
The simultaneity of the disappearance of literature (as aesthetic) and history (as development), which we can observe around us in the academy, points to a fundamental commonality; unraveling one implies unraveling the other, since both are grounded in the same goal-oriented structures that postmodern sensibility opposes. Both civilizational history and autonomous literature are constitutively teleological, dependent on notions of progress toward goals, and they both therefore face resistance from the antidevelopmentalism of contemporary intellectual life.
