The noise of the world

This essay traverses a heterogeneous terrain, finding important links in the ideas of Jacques Derrida and John Cage, and relating these to diverse cultural topics such as film soundtrack design, audio art, Saussurian linguistics, the sound and light shows at the Egyptian pyramids, the analogic nature of digital information, and cybernetics. Furthermore, the essay attempts to create some bridges - through the concept of "perceptual differance" - between the divergent world pictures (to use Heidegger's term) of cognitive psychology (with its quantitative frame of analysis) and the more slippery domain of hermeneutics.
