Berenice Abbott. Think Magazine, February 1962

We are, in our Promethean excesses, the only culture to have invented the perspective of ideal growth, of total performance, up to the supreme stage of reality. But we can no longer measure ourselves against this vertiginous dimension. Modernity (the West) can no longer respond to its own values of unlimited progress and growth. Programming has transformed progress, which was an idea, a great historical idea, into a technolog­ical operation of the world in real time. And infinity, once an ideal abstraction, is materialized as well in infinite growth, the immediate vertigo of profusion. And we are now prisoners of this irreversible dimension – unable to reinvent a finite universe.

A theory is exactly like a box of tools. It has nothing to do with the signifier. It must be useful. It must function. And not for itself. If no one uses it, beginning with the theoretician himself (who then ceases to be a theoretician), then the theory is worthless or the moment is inappropriate. We don't revise a theory, but construct new ones; we have no choice but to make others.
