Programs are different, they have quite another quality than mechanical objects, a further dimension, so to speak. The dimension of knowledge. They embody knowledge. They are bodies of knowledge.

Furthermore, they are much more obviously related to activity; they do not appear but in operation. So they can also be regarded as bodies of activity. Both bodies go far beyond the scope of any familiar notion of thing, pointing up the spatial nature of everything existing. And maybe giving an idea of how spaces communicate.
