Reason never relates directly to an object, but solely to the understanding and by means of it to reason's own empirical use, hence it does not create any concepts (of objects) but only orders them and gives a Objecte Objecte them that unity which they can have in their greatest possible extension,.e., in relation to the totality of series; the understanding does not look to this totality at all, but only to the connection through which series of conditions always come about according to concepts.
