transcend the very conditions of its existence. It is precisely with the Understanding as with the lower faculty. It cannot transcend its limits. It can add no item to the sum of human knowledge, except as it deduces it from a presentation by the Sense. Hence its conditions correspond to those in its associate faculty. It is manifest, then, that a being with only these faculties may construct a _system_, but can never develop a _science_. It can arrange, classify, by such standards as its fancy may select, the phenomena in nature; but this must be in accordance with some sensuous form. _No law can be seen_, by which it ought to be so, and not otherwise. Such classification must always be determined by the number of stamens in the flower, for instance; and that standard, though arbitrary, will be as good as any other, _unless there comes a higher faculty_ which, overlooking all nature, perceives the _a priori_ law working in nature, which gives the ultimate ground for an exhaustive development of a science which in its _idea_ cannot be improved. It is manifest, further, that those conditions, to which we have applied the epithet proper, lie upon the two faculties we have been considering. In this we agree with the Limitists. It now behooves to present the fact that the faculty whose existence was proved in the earlier part of our work, is competent to overlook, and so comprehend nature, and all the conditions of nature, and thereby assign to said conditions their true and inferior place, while it soars out of nature, and intuits those _a priori_ laws which, though the conditions of, are wholly unconditioned _by nature_; but which are both the conditions of and conditioned by the supernatural; and this in an entirely different sense from the other. This is the province of the Pure Reason. Standing on some lofty peak, above all clouds of sense, under the full blaze of eternal truth, the soul sees all nature spread like a vast map before her searching eye, sharply observes, and appreciates all the conditions of nature; and then, while holding it full in the field of her vision, with equal fulness perceives that other land, the spiritual plains of the supernatural, sees them too in all their conditionings; and sees, with a clearness of vision never approximated by the earthly eye, the fact that these supernatural conditions are no deprivation which awaken a want, but that they inhere and cohere, as final ground for absolute plenitude of endowments and fulness of bliss, in the Self-existent Person.
