For we are bringing forward a teleological ground where we endow a concept of an object as if that concept were to be found in nature instead of in ourselves with causality in respect of the object, or rather where we represent to ourselves the possibility of the object on the analogy of a causality of this kind a causality such as we experience in ourselves and so regard nature as possessed of a capacity of its own for acting technically; whereas if we did not ascribe such a mode of operation to nature, its causality would have to be regarded as blind mechanism.
