crisis in the history of our Western mathematics. Such a crisis 
concerned the problems of determining the diagonal of a 
square and the circumference of a circle: a clear case of 
number, the tactile sense, trying to cope with visual and 
pictorial space by reduction of the visual space to itself.

     For the Renaissance, it was the infinitesimal calculus that 
enabled arithmetic to take over mechanics, physics, and 
geometry. The idea of an infinite but continuous and uniform 
process, so basic to the Gutenberg technology of movable 
types, gave rise to the calculus. Banish the infinite process and 
mathematics, pure and applied, is reduced to the state known 
to the pre-Pythagoreans. This is to say, banish the new 
medium of print with its fragmented technology of uniform, 
lineal repeatability, and modern mathematics disappears. 
Apply, however, this infinite uniform process to finding the
