least, as they contain and have established a real and solid advance of human science; so far, too, as I am acquainted with them, and in my sphere understand them. On the other hand, I can not but take exception to that admixture of materialism which has been infused into them by the ruling philosophical system of a previous age, which in France has still so many followers. I honor, too, and love German science, with its diligent and comprehensive research. Nay, I value the natural philosophy of Germany even still more than that of France, since, while it adopts the same great discoveries, it views them in a more spiritual light. As for that idealistic jargon, however, which runs parallel and is interwoven with it, on which, indeed, it was originally based, and from which even now it is any thing but clear—this I can not regard in any other light than, what it really is, an intellectual delusion of the most pernicious kind, and one which will inevitably produce the most destructive and fatal consequences on the human mind.

What has been now said will suffice for our notice of the opposing systems of philosophy. Henceforward we shall have no need to turn our looks to this side, but shall be able to give our attention solely and calmly to the development of that which I have already announced, and have now to communicate to you. Previously, however, to entering upon this subject, it seemed to me advisable, by contrasting the false starting-point with the true center of philosophy, to set the latter before you in a clearer and distincter light.

The dialectical faculty of abstraction is naturally the predominant one, and the most completely evolved in the thinking mind. Accordingly, most thinkers have set it up as the basis of their speculations, in order to arrive the more rapidly at the desired end of an absolute science; or, if the habit of mind be more disposed that way, at an absolute not-knowing, and the rejection of all certainty; which, in the main, is quite as false, and, in this respect, identical with the former. But it is not sufficient to follow any such a partial course, and to start from any one side merely of the human consciousness. On the right and sure road of a complete and thorough investigation, our first duty is to study the human consciousness in its fullness and living development, in all its faculties and powers. And then, in the second place, when, by thus assuming a position in the center, man has enabled himself to take a complete survey of the whole, he may unquestionably proceed to inquire what kind and what degree of knowledge, with such a consciousness, he is capable of attaining, both of the external world and of the suprasensible, and how far the latter is conceivable and its existence possible. Now, just as generally the soul is the principle of all life in nature, so is the thinking soul the center of the human consciousness. But in the thinking soul is comprised the reason which distinguishes, combines, and infers, no less than the fancy which devises, invents, and suggests. Standing in the center between the two, the thinking soul embraces both faculties. But it also forms the turning-point of transition between the understanding and the will; and, as the connecting link, fills up the gulf which otherwise would lie between and divide the two. It comprises, also, all sorts and degrees of conceptions, from the absolutely necessary, precisely definite, and permanently unchangeable, down to those which arise and pass away half involuntarily—from those in no degree clearly developed up to those which have been advanced to the highest clearness of the understanding—those which are witnessed with a calm indifference, and those also which excite a gentle longing or kindle a burning resolve. The thinking soul is the common store-house where the whole of these conceptions are successively lodged. Indeed, to describe it in general terms, it is but the inner pulse of thought, corresponding to the pulsation of the blood in the living body.

This general description, it must be confessed, is very far from being an adequate explanation of the matter, and at best does but imperfectly convey our meaning. But perhaps a different line of thought, however bold and hazardous it may seem, may bring us far more simply to the point at present in view—a more accurate description, namely, of the peculiar property of the human mind, and of the characteristic feature which distinguishes man from other beings equally finite, but endowed in the same manner with consciousness. That the rational soul, or the reason, distinguishes him from the brutes, is a remark common and trite enough. But this is only one aspect of the matter: and must we always cast our looks downward, and never upward? What I mean is this: supposing that there are other created spirits and finite intelligences besides men, might not the comparison of their purely spiritual consciousness with man’s serve, perhaps in an eminent degree, to elucidate the distinctive properties of the human consciousness in that other aspect which is too commonly neglected? I am far from intending to make this matter a subject of investigation in the present place. I take it merely as an hypothesis, warranted, indeed, by universal tradition, and solely as an aid to elucidate the matter in hand. Universal, however, I may well call this tradition, since, agreeing in the main with what Holy Writ asserts, the oldest and most civilized nations of antiquity (among whom I need only mention the Egyptians, and especially the Persians and the Hindoos) have admitted, as a well-established fact, the existence of such finite intelligences and created spirits, invisible indeed to man, but not altogether alien to him. And as for the Greeks and Romans, if occasionally they allude to the genius of Socrates as something strange and singular, this was only because the wise Athenian spoke of this subject in peculiar language, and referred to it more habitually than was the wont of his countrymen and cotemporaries. Otherwise it was the general belief, both of Greeks and Romans, that every man has his guardian spirit or genius. Now this hypothesis being once admitted to be possible, let us inquire in what light were these ancients accustomed to regard, and what ought we to conceive of the peculiar nature of these spiritual beings in conformity with the representation of so universal a tradition?

Now, in the first place, they have always been thought of as pure spiritual beings, having no such gross terrestrial body as man has. At least, if they were supposed to require and possess a body as the organ and medium of their spiritual operations, it was considered to be of a special kind—an ethereal body of light, but invisible to the human eye. But this incorporeity is little more than a negative quality. A more positive and a profounder distinction lies perhaps in this, that these pure spiritual beings are wholly free from that weakness of character, or frailty, which is so peculiar to man. That pervading internal mutability, that undecided vacillation between doing and letting alone, that reciprocation between effort and relaxation—the wide gulf between volition and execution, the thought and the carrying into effect—nothing of all this admits of being applied or transferred to these pure spiritual beings without contradicting the very idea of their essence. It is thus only, or not at all, that we can conceive of them. Coming and going like the lightning, and rapid as the light, they never grow weary of their endless activity. They need no rest, except the spiritual contemplation which constitutes their essence. All their thoughts are marked with unity and identity. With them the conception is at the same time a deed, and the purpose and the execution are simultaneous. Every thing, too, in them has the stamp of eternity. This prerogative, however, has, it must be confessed, its disadvantages. When once they have deviated from the true center, they go on forever in their devious course.

But still,
