only which is true: and the truth is universally placed in the coincidence of the thought with the thing, of the representation with the object represented.

Now the sum of all that is merely OBJECTIVE, we will henceforth call NATURE, confining the term to its passive and material sense, as comprising all the phænomena by which its existence is made known to us. On the other hand the sum of all that is sUBJECTIVE, we may comprehend in the name of the SELF OF INTELLIGENCE. Both conceptions are in necessary antithesis. Intelligence is conceived of as exclusively representative, nature as exclusively represented; the one as conscious, the other as without consciousness. Now in all acts of positive knowledge there is required a reciprocal concurrence of both, namely of the conscious being, and of that which is in itself unconscious. Our problem is to explain this concurrence, its possibility and its necessity.

During the act of knowledge itself, the objective and subjective are so instantly united, that we cannot determine to which of the two the priority belongs. There is here no first, and no second; both are coinstantaneous and one. While I am attempting to explain this intimate coalition, I must suppose it dissolved.

which therefore I give hypothetical antecedence, in order to arrive at the other. But as there are but two factors or elements in the problem, subject and object, and as it is left indeterminate from which of them I should commence, there are two cases equally possible.

1. EITHER THE OBJECTIVE IS TAKEN AS THE FIRST, AND THEN WE HAVE TO ACCOUNT

FOR THE SUPERVENTION OF THE SUBJECTIVE,

WHICH COALESCES WITH IT.

The notion of the subjective is not contained in the notion of the objective. On the contrary they mutually exclude each other. The subjective therefore must supervene to the objective. The conception of nature does not apparently involve the co-presence of an intelligence making an ideal duplicate of it, i. e. representing it. This desk for instance would (according to our natural notions) be, though there should exist no sentient being to look at it. This then is the problem of natural philosophy. It assumes the objective or unconscious nature as the first, and has therefore to explain how intelligence can supervene to it, or how itself can grow into intelligence. If it should appear, that all enlightened naturalists without having distinctly proposed the problem to themselves have yet constantly moved in the line of its solution, it must afford a strong pre

posed, all sciences must proceed from the one or the other, and must tend toward the opposite as far as the equatorial point in which both are reconciled and become identical. The necessary tendence therefore of all natural philosophy is from nature to intelligence; and this, and no other is the true ground and occasion of the instinctive striving to introduce theory into our views of natural phænomena., The highest perfection of natural philosophy would consist in the perfect spiritualization of all the laws of nature into laws of intuition and intellect. The phænomena (the material) must wholly disappear, and the laws, alone (the formal) must remain. Thence it comes, that in nature itself the more the principle of law breaks forth, the more does the husk drop off, the phænomena themselves become more spiritual and at length cease altogether in our consciousness. The optical phænomena are but a geometry, the lines of which are drawn by light, and the materiality of this light itself has already become matter of doubt. In the appearances of magnetism all trace of matter is lost, and of the phænomena of gravitation, which not a few among the most illustrious Newtonians have declared no otherwise com

prehensible than as an immediate spiritual influence, there remains nothing but its law, the execution of which on a vast scale is the mechanism of the heavenly motions. The theory of natural philosophy would then be completed, when all nature was demonstrated to be identical in essence with that, which in its highest known power exists in man as intelligence and self-consciousness; when the heavens and the earth shall declare not only the power of their maker, but the glory and the presence of their God, even as he appeared to the great prophet during the vision of the mount in the skirts of his divinity.

This may suffice to show, that even natural science, which commences with the material phænomenon as the reality and substance of things existing, does yet by the necessity of theorising unconsciously, and as it were instinctively, end in nature as an intelligence; and by this tendency the science of nature becomes finally natural philosophy, the one of the two poles of fundamental science.

2. OR THE SUBJECTIVE IS TAKEN AS THE FIRST,

AND THE PROBLEM THEN IS, HOW THERE SUPERVENES TO IT A COINCIDENT OBJECTIVE.

In the pursuit of these sciences, our success in each, depends on an austere and faithful adherence to its own principles with a careful

tain to the opposite science. As the natural philosopher, who directs his views to the objective, avoids above all things the intermixture of the subjective in his knowledge, as for instance, arbitrary suppositions or rather suffictions, occult qualities, spiritual agents, and the substitution of final for efficient causes; so on the other hand, the transcendental or intelligential philosopher is equally anxious to pre clude all interpolation of the objective into the subjective principles of his science, as for instance the assumption of impresses or configu rations in the brain, correspondent to miniature pictures on the retina painted by rays of light from supposed originals, which are not the immediate and real objects of vision, but deductions from it for the purposes of explanation. This purification of the mind is effected by an absolute and scientific scepticism to which the mind voluntary determines itself for the spe cific purpose of future certainty. Des Cartes who (in his meditations) himself first, at least of the moderns, gave a beautiful example of this voluntary doubt, this self-determined indetermination, happily expresses its utter difference from the scepticism of vanity or irreligion: Nec tamen in eo scepticos imitabar, qui dubitant tantum ut dubitent, et preter incerti tudinem ipsam nihil quærunt. Nam contra
