In republishing the Work in this country, I could wish that it might be received by all, for whose instruction it was designed, simply as a didactic work, on its own merits, and without controversy. I must not, however, be supposed ignorant of its bearing upon those questions, which have so often been, and still are, the prevailing topics of theological controversy among us. It was indeed incumbent on me, before inviting the attention of the religious community to the Work, to consider its relation to existing opinions, and its probable influence on the progress of truth. This I have done with as severe thought as I am capable of bestowing upon any subject, and I trust too with no want of deference and conscientious regard to the feelings and opinions of others. I have not attempted to disguise from myself, nor do I wish to disguise from the readers of the Work, the inconsistency of some of its leading principles with much that is taught and received in our theological circles. Should it gain much of the public attention in any way, it will become, as it ought to do, an object of special and deep interest to all, who would contend for the truth, and labour to establish it upon a permanent basis. I venture to assure such, even those of them who are most capable of comprehending the philosophical grounds of truth in our speculative systems of theology, that in its relation to this whole subject they will find it to be a Work of great depth and power, and, whether right or wrong, eminently deserving their attention. It is not to be supposed that all who read, or even all who comprehend it, will be convinced of the soundness of its views, or be prepared to abandon those which they have long considered essential to the truth. To those, whose understandings by long habit have become limited in their powers of apprehension, and as it were identified with certain schemes of doctrine, certain modes of contemplating all that pertains to religious truth, it may appear novel, strange, and unintelligible, or even dangerous in its tendency, and be to them an occasion of offence. But I have no fear that any earnest and single-hearted lover of the truth as it is in Jesus, who will free his mind from the idols of preconceived opinion, and give himself time and opportunity to understand the Work by such reflection as the nature of the subject renders unavoidable, will find in it any cause of offence, or any source of alarm. If the Work become the occasion of controversy at all, I should expect it from those, who, instead of reflecting deeply upon the first principles of truth in their own reason and conscience and in the word of God, are more accustomed to speculate—that is, from premises given or assumed, but considered unquestionable, as the constituted point of observation, to look abroad upon the whole field of their intellectual vision, and thence to decide upon the true form and dimensions of all which meets their view. To such I would say with deference, that the merits of this Work cannot be determined by the merely relative aspect of its doctrines, as seen from the high ground of any prevailing metaphysical or theological system. Those on the contrary who will seek to comprehend it by reflection, to learn the true meaning of the whole and of all its parts, by retiring into their own minds and finding there the true point of observation for each, will not be in haste to question the truth or the tendency of its principles. I make these remarks because I am anxious, as far as may be, to anticipate the causeless fears of all, who earnestly pray and labour for the promotion of the truth, and to preclude that unprofitable controversy, which might arise from hasty or prejudiced views of a Work like this. At the same time I should be far from deprecating any discussion which might tend to unfold more fully the principles which it teaches, or to exhibit more distinctly its true bearing upon the interests of theological science and of spiritual religion. It is to promote this object, indeed, that I am induced in the remarks which follow to offer some of my own thoughts on these subjects, imperfect I am well aware, and such as, for that reason, as well as others, worldly prudence might require me to suppress. If, however, I may induce reflecting men, and those who are engaged in theological inquiries especially, to indulge a suspicion that all truth, which it is important for them to know, is not contained in the systems of doctrine usually taught, and that this Work may be worthy of their serious and reflecting perusal, my chief object will be accomplished. I shall of course not need to anticipate in detail the contents of the Work itself, but shall aim simply to point out what I consider its distinguishing and essential character and tendency, and then direct the attention of my readers to some of those general feelings and views on the subjects of religious truth, and of those particulars in the prevailing philosophy of the age, which seem to me to be exerting an injurious influence on the cause of theological science and of spiritual religion, and not only to furnish a fit occasion, but to create an imperious demand, for a Work like that which is here offered to the public.
In regard then to the distinguishing character and tendency of the Work itself, it has already been stated to be didactic, and designed to aid reflection on the principles and grounds of truth in our own being; but in another point of view, and with reference to my present object, it might rather be denominated a philosophical statement and vindication of the distinctively spiritual and peculiar doctrines of the christian system. In order to understand more clearly the import of this statement, and the relation of the Author's views to those exhibited in other systems, the reader is requested to examine in the first place, what he considers the peculiar doctrines of Christianity, and what he means by the terms spirit and spiritual. A synoptical view of what he considers peculiar to Christianity as a revelation is given in Aphorism VII., on Spiritual Religion, and, if I mistake not, will be found essentially to coincide, though not perhaps in the language employed, with what among us are termed the Evangelical doctrines of religion. Those who are anxious to examine further into the orthodoxy of the Work in connection with this statement, may consult the articles on original sin and redemption,[8] though I must forewarn them that it will require much study in connection with the other parts of the Work, before one unaccustomed to the Author's language, and unacquainted with his views, can fully appreciate the merit of what may be peculiar in his mode of treating those subjects. With regard to the term spiritual, it may be sufficient to remark here, that he regards it as having a specific import, and maintains that in the sense of the New Testament, spiritual and natural are contradistinguished, so that what is spiritual is different in kind from that which is natural, and is in fact super-natural. So, too, while morality is something more than prudence, religion, the spiritual life, is something more than morality.
In vindicating the peculiar doctrines of the Christian system so stated, and a faith in the reality of agencies and modes of being essentially spiritual or supernatural, he aims to show their consistency with reason and with the true principles of philosophy, and that indeed, so far from being irrational, christian faith is the perfection of human reason. By reflection upon the subjective grounds of knowledge and faith in the human mind itself, and by an analysis of its faculties, he developes the distinguishing characteristics and necessary relations of the natural and the spiritual in our modes of being and knowing, and the all-important fact, that although the former does not comprehend the latter, yet neither does it preclude its existence. He proves, that "the scheme of Christianity, * * * though not discoverable by human reason, is yet in accordance with it; that link follows link by necessary consequence; that Religion passes out of the ken of
