And it is even herein that philosophy will most display its art, or, rather, its intellectual power over the minds of men. It is in this, pre-eminently, that lies its vocation. But if, on the contrary, it makes this mission to consist rather in demonstrating, in a strictly scientific form, the existence of a Deity, with its natural train of those eternal verities—the immortality of the soul, and the freedom of the will, then at the very first outset it will lose sight of its true aim, and set up a false one. For, were such a demonstration possible, still nothing essential would be gained by its actual attainment. For, in such a case, the existence of God, and God himself, would naturally become dependent, in thought at least, on that from and by means of which the proof was established, and would, consequently, appear to us no longer as the first cause of all, but, rather, a secondary and derivative being. In such the primal essence would be made to depend on our human knowledge and science of reasoning, so to speak; the latter must, in the plenitude of its power, first confer upon and guaranty to the former its existence. This would, indeed, be a complete inversion of the true and natural order of things, such as, alas, has but too often occurred and manifested itself in actual experience.

These remarks, however, must be understood as applying to a strict demonstration of this great verity, or at least to all attempts of the kind. To point to this truth, to trace every indication of it, to elucidate it, to confirm it by analogy or other corroborative evidences, is quite a different matter. All this is perfectly allowable. But God does not allow his existence to be proved. By force of reasoning such a belief is not to be impressed on the mind of that man who is unwilling spontaneously to admit it. As life generally, so also this supreme life must be learned and concluded from every man’s own experience; it must be adopted with the vividness of a feeling.

Let us now, for a moment, revert to the old scholastic forms and the designations usually given in the schools to the several philosophical sciences, and compare with them the division on which our present disquisitions are based. We might, in this respect, say that the first five sections of our treatise have been exclusively devoted to psychology; though not indeed in the ordinary narrow sense of the word, but in one far more extensive, and embracing the whole universe. According to this wider extent and signification of psychology, we have considered the soul relatively, first of all, to the whole of philosophy and its several systems; secondly, to moral life; and, lastly, to revelation, to nature, and to God Himself. The three following Lectures were devoted to an examination of the divine order of things in the several spheres of existence, and to the indications of a ruling Providence discoverable therein. They constitute, therefore, a species of theology; but one, however, empirically conceived and historically worked out from observations in nature and in history, not only in the annals of the external world, but also in the spiritual history of the progressive terms in the development of truth. Such a theological essay exactly corresponds to that notion we so lately advanced, of an applied or mixed science of theology as the peculiar sphere for this part or branch of philosophy which concerns itself with the doctrine of the supreme essence, and the right understanding thereof.

Now if, in compliance with olden forms of division and a scholastic phraseology, it be necessary to deliver a scheme of ontology as the philosophical science and cognition of really existent things, and also of their true and real essence, it is clear that such is only conceivable and possible by means of such an applied theology. For how can things be truly real, and how can they as such be known in their inmost essence, except so far as they have their existence and determination in God, and, in this respect, admit of being known by us?

In any case, however, the name of natural theology, which ever and anon we still hear applied to the philosophical cognition of the Divine Being and His existence, ought carefully to be avoided. Such a designation is based on a thorough misconception and total inversion of ideas. Every system of theology that is not supernatural, or at least that does not profess to be so, but pretends to understand naturally the idea of God, and regards the knowledge of the divine essence as a branch of natural science, or derives the idea simply from nature, is even on that account false. Missing and entirely mistaking its proper object, it must, in short, prove absolutely null and void. Properly, indeed, this inquiry needs no peculiar word nor special division and scientific designation. The name generally of philosophy, or specially of a philosophy of God, is perfectly sufficient to designate the investigation into science and faith, and their reciprocal relation—their abiding discord, or its harmonious reconciliation and intrinsic concord. And this is properly the point which is here in question; it forms the essential part of the topic which we have at present to examine.

The internal schism in the faith itself I formerly excluded from our inquiry, as not lying properly within the limits of philosophy, and belonging to a higher tribunal. I at the same time expressed my conviction that God alone could universally and totally reconcile it. By this, however, I would not by any means wish to be understood as asserting that works on this subject, written with a thorough knowledge of historical facts, and in a luminous and instructive style, can not contribute much to the refutation of error. Works of this nature may, in their degree, tend to bring about a mutual approximation of sentiment. For they serve to elucidate and clear up points which, even though they do not involve the essential articles of positive belief; do, nevertheless, greatly and extensively co-operate in keeping alive a mutual spiritual alienation and estrangement of mind. The great merit of treatises of this kind, when composed with high intellectual powers and in that noble spirit which is at once just and desirous of peace, must not in any case be denied or depreciated. Nevertheless, it is idle to pretend that the influence of such essays, whether greater or less, is not confined to a limited sphere, extending to a few individuals, or at most to classes.

To judge by the usual course of the divine order in the realm of truth, a total conversion of the whole mind of the age, or a reawakening of entire nations, is only to be expected from a higher and universal impulse imparted from above. As a preparation, however, for that divine peace in a universal unity of faith, which so repeatedly and so many ways is promised most distinctly even to this life, nothing can be so effective as to remove, if possible, or at least to reconcile, that triple discord already described as dividing and distracting the inner man. And this is a matter which, as lying within the sphere of human consciousness and science, unquestionably belongs to the domain of philosophical investigation. And it is even the duty of philosophy, whenever it follows its prevailing mediatory and atoning tendency, to attempt scientifically to bring about the reconciliation of that strife, and, undiscouraged by repeated failures, still to labor to re-establish the perfect and profound harmony of consciousness and of life.

Now the first dissension, that, viz., between science and faith, whether actual or apparent, requires for its removal before all things a mutual understanding and compromise. The second dissension between faith in general, even a mere philosophical and natural faith, and that unbelief which is so general and prevalent in our age, can only end with the perfect triumph of the truth. For only by the full light of divine knowledge and truth—by the triumphant exposition of this true light, and by the magic power of such a display on the minds of men—shall doubt and infidelity be fully eradicated and destroyed. The third dissension, between both faith and science on the one hand, and life on the other, needs, for the removal of all misunderstanding, something more than a mere peace and compromise on the disputed points. For this purpose there is required a thorough union of both carried out into fruitful and practical application, by which the living faith and the living science may evince themselves as such, and manifest their true and wholesome influence on life, however at present estranged from and adverse to it.

The second and the third of these dissensions are reserved for consideration in the two following Lectures; but the first, that, viz., which subsists between faith and science, is to form the subject, and its reconciliation the problem of our present disquisition.

Now, is this dissension necessarily and really grounded in the thing itself, and in the nature of the thing? Or, rather, does the blame of it lie with men, and in their defective apprehension and form? I have no hesitation in saying that a living faith and a living science will never be at issue together, at least on essential points. In three cases, no doubt, a dissension, a reciprocal misunderstanding, and endless conflict between both is perfectly conceivable. It is possible, either when the faith is a mere matter of memory and of a few acquired notions, rather than a deeply-rooted conviction of the soul. Or, secondly, since all the faculties of the human mind ought to co-operate in giving a full internal development and an external shape to the truth thus divinely imparted, it may spring up even when the soul receives it with a full love, but is nevertheless principally, or at least too much, under the dominion of a lively fancy, to the exclusion of a due admixture of clearness of understanding, and the circumspection which belongs to the distinguishing judgment. Or, thirdly, it may arise, on the other side, when a conceited and presumptuous science seeks to establish itself rather than truth, and places more dependence on its own conclusions than on its announcements.
