“ I mean by this that the conceiving or theorizing faculty—the mind's middle department—functions exclusively for the sake of ends that do not exist at all in the world of impressions we receive by way of our senses, but are set by our emotional and practical subjectivity altogether. [2] It is a transformer of the world of our impressions into a totally different world,—the world of our conception; and the transformation is effected in the interests of our volitional nature, and for no other purpose whatsoever. ”
