'More matter, and less art,' another says in that same treatise on art and speculation. Now inasmuch as this art and science derives all its distinction and lustre from that new light on the human estate of which it was to be the vehicle, somebody must find the trick of it, so as to be able to bring out _that doctrine_ by its help, before we can be prepared to understand the real worth of this invention. It would be premature to undertake to set it forth fully, till that is accomplished. There must be a more elaborate exhibition of that science, before the art of its transmission can be fully treated; we cannot estimate it, till we see how it strikes to the root of the new doctrine, how it begins with its beginning, and reaches to its end: we cannot estimate it till we see its relation, its essential relation, to that new doctrine of the human nature, and that new doctrine of state, which spring from the doctrine of nature in general, which is _the_ doctrine, which is the beginning and the end of the new science. We find here on the surface, as we find everywhere in this comprehensive treatise, much apparent parade of division and subdivision, and the author appears to lay much stress upon this, and seems disposed to pride himself upon his dexterity in chopping up the subject as finely as possible, and keeping the parts quite clear of one another; and sometimes, in his distributions, putting those points the farthest apart which are the most nearly related, though not so far, that they cannot 'look towards each other,' though it may be, as the other says, '_obliquely_.' He evidently depends very much on his arrangement, and seems, indeed, to be chiefly concerned about that, when he comes to the more critical parts of his subject. But it is to _the continuities_ which underlie these separations, to which he directs the attention of those to whom he speaks in earnest, and not in particular cases only. '_Generally_,' he says, '_let this be a rule_, that all partitions of knowledge be accepted rather for LINES and VEINS, than for _sections_ and _separations_, and that _the continuance and entireness of knowledge_ be preserved. For the _contrary hereof_,' he says, 'is that which has made PARTICULAR SCIENCES BARREN, SHALLOW, and ERRONEOUS, while they have not been nourished and maintained from the _common_ fountain.' For this is the ONE SCIENCE, the deep, the true, the fruitful one, the fruitful because the ONE.
