From a 1965 interview with sculptor Jean Tinguely.

What happens at the base of our civilization is incredible. We go round in circles, there’s no question about that. But insofar as it’s dynamic, we advance. This domination by machine has produced an America that is a mad circus of automated, industrial machinery, such as we’ve not yet seen in Europe. Yet even here we’ve grown oblivious to the fact that in Paris there is such a mass of machinery in the street that one hardly moves. But it will get worse: you’re going to see real madness! This kind of madness preoccupies me, and I think that with my machines I point out the stupidity of the machine; the enormous uselessness of this gigantic effort.
