‘We have two ways of positing the outside world.

Numbers. Through their effect there is a plurality of individuals: sympathy, order harmony, beauty, etc. […] in short, everything that is of mind.

Space. This gives us objects “having extension”

In the spatial world the images of the numerical world are projected, first by nature itself, then by men and above all by artists. It can be said that our duty on earth and during the whole of our life consists precisely in this projection of forms issued forth from numbers, and that you, the artists, fulfill that moral law to the highest degree. Not only is it possible to appeal simultaneously to geometry and to numbers, but to do so is the true purpose of our life.’
