At a certain level of abstraction you leave the human behind and enter the realm of engineering.
There I was thinking about sound denoting an operation, a movement, and how a point is reached at which that movement, that operation, is rationalised into engineering, away from the exigencies of an individual human body, abstracted into an energy equation.
To hit a drum becomes a mechanised procedure of downward pressure, rationalised, a piston, without the complex rotational, hinged architecture of shoulder, elbow wrist, bicep, tricep, hand etc
A New Operational Field
Since the energy of objects is abstract, their functionality is limitless: just as there
is now scarcely any substance that has no plastic equivalent, so there is no gesture
that cannot be replaced by technology. The simplest of mechanisms is liable to
replace and subsume a whole set of gestures, concentrating their effectiveness and
becoming independent not only of the agent but also of the material acted upon.
Form and utility of the tool, raw material, energy applied - all these factors have
changed. Thus the matter dealt with has undergone infinite differentiation - even
to the point of disappearing altogether: that processed by a radio, for example, is
information. The transformation of energy has entailed that of both materials and
functions, for technology is not content merely to encapsulate earlier gestures, it
also invents new operations, and above all splits up the operational field into
completely different functions or sets of functions. Man's abstract relationship
to his (technical) objects, his 'spectacular alienation', is thus less a matter of his
gestures having been replaced than of the abstractness of the very way in which
functions have been split up, and the impossibility of any analogical apprehension
of this splitting-up by reference to earlier gestures. Only an abstract (never an
unmediated) intelligence can adapt to the new technical structures; meanwhile,
man himself has yet to adapt to the increasingly exclusive use of these higher
functions of intelligence and calculation. Resistance here has deep roots, and
creates an irreparable delay. Man has become less rational than his own objects,
which now run ahead of him, so to speak, organizing his surroundings and thus
appropriating his actions.
