The real scandal of Galileo’s work lay not so much in his discovery, or rediscovery, that the earth revolved around the sun, but in his constitution of an infinite, and infinitely open space. In such a space the place of the Middle Ages turned out to be dissolved. as it were; a thing’s place was no longer anything but a point in its movement, just as the stability of a thing was only its movement indefinitely slowed down. In other words, starting with Galileo and the seventeenth century, extension was substituted for localization.
