(space) which is met with in myself as a representation and yet a priori, renders intelligible the unity of many rules resulting from the construction of that concept, which are purposive for many possible designs.

But this purposiveness does not imply a purpose or any other ground whatever. It is quite different if I meet with order and regularity in complexes of things, external to myself, enclosed within certain boundaries; as, e.g. in a garden, the order and regularity of the trees, flower-beds, and walks. These I cannot expect to derive a priori from my bounding of space made after a rule of my own; for this order and regularity are existing things which must be given empirically in order to be known, and not a mere representation in myself determined a priori
