achieve the just named and so desirable result; and by the mode heretofore indicated. It is required, then, to _prove_ that there is a faculty belonging to the human soul, essentially diverse from the Sense or the Understanding; a faculty peculiar and unique, which possesses such qualities as have commonly been ascribed by its advocates to the Pure Reason; and thereby to establish such faculty as a fact, and under that name. Previous to bringing forward any proofs, it is important to make an exact statement of what is to be proved. To this end, let the following points be noted:-- _a._ Its modes of activity are essentially diverse from those of the Sense or Understanding. The Sense is only capacity. According to the laws of its construction, it receives impressions from objects, either material, and so in a different place from that which it occupies, or imaginary, and so proceeding from the imaging faculty in itself. But it is only capacity to receive and transmit impressions. The Understanding, though more than this, even faculty, is faculty shut within the limits of the Sense. According to its laws, it takes up the presentations of the Sense, analyzes and classifies them, and deduces conclusions: but it can attain to nothing more than was already in the objects presented. It can construct a system; it cannot develop a science. It can observe a relation it cannot intuit a law. What we seek is capacity, but of another and higher kind from that of the Sense. Sense can have no object except such, at least, as is constructed out of impressions received from without. What we seek does not observe outside phenomena; and can have no object except as inherent within itself. It is faculty moreover, but not faculty walled in by the Sense. It is faculty and capacity in one, which, possessing inherent within itself, as objects, the _a priori_ conditional laws of the Universe, and the _a priori_ conditional ideal forms which these laws, standing together according to their necessary relations, compose, transcends, in its activity and acquisitions, all limitations of a _Nature_; and attends to objects which belong to the Supernatural, and hence which absoluteness qualifies. We observe, therefore,
