For pure speculative reason has this peculiarity lll about it, that it can and should measure its own capacity a according to the different ways for choosing the objects of its thinking, and also completely enumerate the manifold ways of putting problemsc before itself, so as to catalog the entire preliminary sketch of a whole system of metaphysics; because, regarding the first point, in a priori cognition nothing can be ascribed to the objectsd except what the thinking subject takes out of itself, and regarding the second, pure speculative reason is, in respect of principlese of cognition, a unity entirely separate and subsisting for itself, in which, as in an organized body, every part exists for the sake of all the others as all the others exist for its sake, and no principle!
