insinuation, that its depths are not worth exploring—which is more than the objector knows—or a confession, that—with all his professed love of truth and knowledge—he prefers to "sleep after dinner." The misfortune is, that men have been cheated into a belief, that all philosophy and metaphysics worth knowing are contained in a few volumes, which can be understood with little expense of thought; and that they may very well spare themselves the vexation of trying to comprehend the depths of "Coleridge's Metaphysics." According to the popular notions of the day, it is a very easy matter to understand the philosophy of mind. A new work on philosophy is as easy to read as the last new novel; and superficial, would-be scholars, who have a very sensible horror at the thought of studying Algebra, or the doctrine of fluxions, can yet go through a course of moral sciences, and know all about the philosophy of the mind.
Now why will not men of sense, and men who have any just pretensions to scholarship, see that there must of necessity be gross sophistry somewhere in any system of metaphysics, which pretends to give us an adequate and scientific self-knowledge—to render comprehensible to us the mysterious laws of our own inward being, with less manly and persevering effort of thought on our part, than is confessedly required to comprehend the simplest of those sciences, all of which are but some of the phænomena from which the laws in question are to be inferred?—Why will they not see and acknowledge—what one would suppose a moment's reflection would teach them—that to attain true self-knowledge by reflection upon the objects of our inward consciousness—not merely to understand the motives of our conduct as conscientious Christians, but to know ourselves scientifically as philosophers—must, of necessity, be the most deep and difficult of all our attainments in knowledge? I trust that what I have already said will be sufficient to expose the absurdity of objections against metaphysics in general, and do something towards showing, that we are in actual and urgent need of a system somewhat deeper than those, the contradictions of which have not without reason made the name of philosophy a terror to the friends of truth and of religion. "False metaphysics can be effectually counteracted by true metaphysics alone; and if the reasoning be clear, solid, and pertinent, the truth deduced can never be the less valuable on account of the depth from which it may have been drawn." It is a fact, too, of great importance to be kept in mind, in relation to this subject, that in the study of ourselves—in attaining a knowledge of our own being—there are truths of vast concernment, and lying at a great depth, which yet no man can draw for another. However the depth may have been fathomed, and the same truth brought up by others, for a light and a joy to their own minds, it must still remain, and be sought for by us, each for himself, at the bottom of the well.
The system of philosophy here taught does not profess to make men philosophers, or—which ought to mean the same thing—to guide them to the knowledge of themselves, without the labour both of attention and of severe thinking. If it did so, it would have, like the more popular works of philosophy, far less affinity than it now has, with the mysteries of religion, and those profound truths concerning our spiritual being and destiny, which are revealed in the things hard to be understood of St. Paul and of the beloved disciple. For I cannot but remind my readers again, that the Author does not undertake to teach us the philosophy of the human mind, with the exclusion of the truths and influences of religion. He would not undertake to philosophize respecting the being and character of man, and at the same time exclude from his view the very principle which constitutes his proper humanity: he would not, in teaching the doctrine of the solar system, omit to mention the sun, and the law of gravitation. He professes to investigate and unfold the being of man as man, in his higher, his peculiar, and distinguishing attributes. These it is, which are hard to be understood, and to apprehend which requires the exercise of deep reflection and exhausting thought. Nor in aiming at this object would he consider it very philosophical to reject the aid and instruction of eminent writers on the subject of religion, or even of the volume of Revelation itself. He would consider St. Augustine as none the less a philosopher, because he became a Christian. The Apostles John and Paul were, in the view of this system of philosophy, the most rational of all writers, and the New Testament the most philosophical of all books. They are so because they unfold more fully, than any other, the true and essential principles of our being; because they give us a clearer and deeper insight into those constituent laws of our humanity, which as men, and therefore as philosophers, we are most concerned to know. Not only to those, who seek the practical self-knowledge of the humble, spiritually-minded Christian, but to those also, who are impelled by the "heaven descended γνωθι σεαυτον" to study themselves as philosophers, and to make self-knowledge a science, the truths of Scripture are a light and a revelation. The more earnestly we reflect upon these and refer them, whether as Christians or as philosophers, to the movements of our inward being—to the laws which reveal themselves in our own consciousness, the more fully shall we understand, not only the language of Scripture, but all that most demands and excites the curiosity of the genuine philosopher in the mysterious character of man. It is by this guiding light, that we can best search into and apprehend the constitution of that "marvellous microcosm," which, the more it has been known, has awakened more deeply the wonder and admiration of the true philosopher in every age.
Nor would the Author of this Work, or those who have imbibed the spirit of his system, join with the philosophers of the day in throwing aside and treating with a contempt, as ignorant as it is arrogant, the treasures of ancient wisdom. He, says the son of Sirach, that giveth his mind to the law of the Most High, and is occupied in the meditation thereof, will seek out the wisdom of all the ancient. In the estimation of the true philosopher, the case should not be greatly altered in the present day; and now that two thousand years have added such rich and manifold abundance to those ancient "sayings of the wise," he will still approach them with reverence, and receive their instruction with gladness of heart. In seeking to explore and unfold these deeper and more solemn mysteries of our being, which inspire us with awe, while they baffle our comprehension, he will especially beware of trusting to his own understanding, or of contradicting, in compliance with the self-flattering inventions of a single age, the universal faith and consciousness of the human race. On such subjects, though he would call no man master, yet neither would he willingly forego the aids to be derived, in the search after truth, from those great oracles of human wisdom—those giants in intellectual power who from generation to generation were admired and venerated by the great and good. Much less could he think it becoming, or consistent with his duty to hazard the publication of his own thoughts on subjects of the deepest concernment, and on which minds of greatest depth and power had been occupied in former ages, while confessedly ignorant alike of their doctrines and of the arguments by which they are sustained.
It is in this spirit, that the Author of the work here offered to the public has prepared himself to deserve the candid and even confiding attention of his readers, with reference to the great subject of which he treats.
And although the claims of the Work upon our attention, as of every other work, must depend more upon its inherent and essential character, than upon the worth and authority of its Author, it may yet be of service to the reader to know, that he is no hasty or unfurnished adventurer in the department of authorship to which the Work belongs. The discriminating reader of this Work cannot fail to discover his profound knowledge of the philosophy of language, the principles of its construction, and the laws of its interpretation. In others of his works, perhaps more fully than in this, there is evidence of an unrivalled mastery over all that pertains both to logic and philology. It has been already intimated, that he is no contemner of the great writers of antiquity and of their wise sentences; and probably few English scholars, even in those days when there were giants of learning in Great Britain, had minds more richly furnished with the treasures of ancient lore. But especially will the reader of this Work observe with admiration the profoundness of his philosophical attainments, and his thorough and intimate knowledge, not only of the works and systems of Plato and Aristotle, and of the celebrated philosophers of modern times, but of those too much neglected writings of the Greek and Roman Fathers, and of the great leaders of the Reformation, which more particularly qualified him for discussing the subjects of the present Work. If these qualifications, and—with all these, and above all—a disposition professed and made evident seriously to value them, chiefly as they enable him more fully and clearly to apprehend and illustrate the truths of the Christian system—if these, I say, can give an Author a claim to serious and thoughtful
