The mere multiplicity and complication of facts in this department of enquiry, have been generally regarded as rendering such an attempt hopeless. In any social problem of importance, we invariably feel that to embrace the whole of the circumstances, with all their results and dependencies, is really out of our power, and we are forced to content ourselves with a judgment formed on what appear to us the principal facts. Thus arise those limited truths, admitting of exceptions, of qualification, of partial application, on which we are fain to rely in the conduct of human affairs. In framing his measures, how often is the statesman, or the jurist, made aware of the utter impossibility of guarding them against every species of objection, or of so constructing them that they shall present an equal front on every side! How still more keenly is the speculative politician made to feel, when giving in his adherence to some great line of policy, that he cannot gather in under his conclusions all the political truths he is master of! He reluctantly resigns to his opponent the possession, or at least the usufruct, of a certain class of truths which he is obliged to postpone to others of more extensive or more urgent application.

But this multiplicity and complication of facts may merely render the task of the Sociologist extremely difficult, not impossible; and the half truths, and the perplexity of thought above alluded to, may only prove that his scientific task has not yet been accomplished. Nothing is here presented in the nature of the subject to exclude the strict application of the method. There is, however, one essential, distinctive attribute of human society which constitutes a difference in the nature of the subject, so as to render impossible the same scientific survey and appreciation of the social phenomena of the world that we may expect to obtain of the physical. This is the gradual and incessant developement which humanity has displayed, and is still displaying. Who can tell us that that experience on which a fixed and positive theory of social man is to be formed, is all before us? From age to age that experience is enlarging.

In all recognized branches of science nature remains the same, and continually repeats herself; she admits of no novelty; and what appears new to us, from our late discovery of it, is as old as the most palpable sequence of facts that, generation after generation, catches the eye of childhood. The new discovery may disturb our theories, it disturbs not the condition of things. All is still the same as it ever was. What we possessed of real knowledge is real knowledge still. We sit down before a maze of things bewildering enough; but the vast mechanism, notwithstanding all its labyrinthian movements, is constant to itself, and presents always the same problem to the observer. But in this department of humanity, in this sphere of social existence, the case is otherwise. The human being, with hand, with intellect, is incessantly at work—has a progressive movement—grows from age to age. He discovers, he invents, he speculates; his own inventions react upon the inventor; his own thoughts, creeds, speculations, become agents in the scene. Here new facts are actually from time to time starting into existence; new elements are introduced into society, which science could not have foreseen; for if they could have been foreseen, they would already have been there. A new creed, even a new machine, may confound the wisest of speculations. Man is, in relation to the science that would survey society, a creator. In short, that stability in the order of events, that invariable recurrence of the same linked series, on which science depends for its very existence, here, in some measure, fails us. In such degree, therefore, as humanity can be described as progressive, or developing itself, in such degree is it an untractable subject for the scientific method. We have but one world, but one humanity before us, but one specimen of this self developing creature, and that perhaps but half grown, but half developed. How can we know whereabouts we are in our course, and what is coming next? We want the history of some extinguished world in which a humanity has run its full career; we need to extend our observation to other planets peopled with similar but variously developed inhabitants, in order scientifically to understand such a race as ours.

What, for example, could be more safely stated as an eternal law of society than that of property?—a law which so justly governs all our political reasonings, and determines the character of our political measures the most prospective—a law which M. Comte has not failed himself to designate as fundamental. And yet, by what right of demonstration can we pronounce this law to be inherent in humanity, so that it shall accompany the race during every stage of its progress? That industry should be rewarded by a personal, exclusive property in the fruits of industry, is the principle consecrated by our law of property, and to which the spontaneous passions of mankind have in all regions of the earth conducted. Standing where we do, and looking out as far as our intellectual vision can extend, we pronounce it to be the basis of society; but if we added that, as long as the world lasts, it must continue to be the basis of society, that there are no elements in man to furnish forth, if circumstances favoured their development, a quite different principle for the social organization, we feel that we should be overstepping the modest bounds of truth, and stating our proposition in terms far wider and more absolute than we were warranted. Experiments have been made, and a tendency has repeatedly been manifested, to frame an association of men in which the industry of the individual should have its immediate reward and motive in the participated prosperity of the general body—where the good of the whole should be felt as the interest of each. How such a principle is to be established, we confess ourselves utterly at a loss to divine; but that no future events unforeseen by us, no unexpected modification of the circumstances affecting human character, shall ever develop and establish such a principle—this is what no scientific mind would venture to assert. Our knowledge is fully commensurate to our sphere of activity, nor need it, nor can it, pass beyond that sphere. We know that the law of property now forms the basis of society; we know that an attempt to abrogate it would be the signal for war and anarchy, and we know this also, that at no time can its opposite principle be established by force, because its establishment will require a wondrous harmony in the social body; and a civil war, let the victory fall where it may, must leave mankind full of dissension, rancour, and revenge. Our convictions, therefore, for all practical purposes, can receive no confirmation. If the far future is to be regulated by different principles, of what avail the knowledge of them, or how can they be intelligible to us, to whom are denied the circumstances necessary for their establishment, and for the demonstration of their reasonableness?

"The great Aristotle himself," says M. Comte, speaking of the impossibility of any man elevating himself above the circumstances of his age—"The great Aristotle himself, the profoundest thinker of ancient times, (la plus forte tête de toute l'antiquité,) could not conceive of a state of society not based on slavery, the irrevocable abolition of which commenced a few generations afterwards."—Vol. iv. p.38. In the sociology of Aristotle, slavery would have been a fundamental law.

There is another consideration, not unworthy of being mentioned, which bears upon this matter. In one portion of M. Comte's work, (we cannot now lay our hand upon the passage,) the question comes before him of the comparative happiness of the savage and the civilized man. He will not entertain it, refuses utterly to take cognizance of the question, and contents himself with asserting the fuller development of his nature displayed by the civilized man. M. Comte felt that science had no scale for this thing happiness. It was not ponderable, nor measurable, nor was there an uniformity of testimony to be collected thereon. How many of our debates and controversies terminate in a question of this kind—of the comparative happiness of two several conditions? Such questions are, for the most part, practically decided by those who have to feel; but to estimate happiness by and for the feelings of others, would be the task of science. Some future Royal Society must be called upon to establish a standard measure for human felicity.

We are speaking, it will be remembered, of the production of a science. A scientific discipline of mind is undoubtedly available in the examination of social questions, and may be of eminent utility to the moralist, the jurist, and the politician—though it is worthy of observation that even the habit of scientific thought, if not in some measure tempered to the occasion, may display itself very inconveniently and prejudicially in the determination of such questions. Our author, for instance, after satisfying himself that marriage is a fundamental law of society, is incapable of tolerating any infraction whatever of this law in the shape of a divorce. He would give to it the rigidity of a law of mechanics; he finds there should be cohesion here, and he will not listen to a single case of separation: forgetful that a law of society may even be the more stable for admitting exceptions which secure for it the affection of those by whom it is to be reverenced and obeyed.

With relation to the past, and in one point of view—namely, so far as regards the development of man in his speculative career—our Sociologist has endeavoured to supply a law which shall meet the peculiar exigencies of his case, and enable him to take a scientific survey of the history of a changeful and progressive being. At the threshold of his work we encounter the announcement of a new law, which has regulated the development of the human mind from its rudest state of intellectual existence. As this law lies at the basis of M. Comte's system—as it is perpetually referred to throughout his work—as it is by this law he proceeds to view history in a scientific manner—as, moreover, it is by aid of this law that he undertakes to explain the provisional existence of all theology, explaining it in the past, and removing it from the future—it becomes necessary to enter into some examination of its claims, and we must request our readers' attention to the following statement of it:—

"In studying the entire development of the human intelligence in its different spheres of activity, from its first efforts the most simple up to our own days, I believe I have discovered a great fundamental law, to which it is subjected by an invariable necessity, and which seems to me capable of being firmly established, whether on those proofs which are furnished by a knowledge of our organization, or on those historical verifications which result from an attentive examination of the past. The law consists in this—that each of our principal conceptions, each branch of our knowledge, passes successively through three different states of theory: the theologic, or fictitious; the metaphysic, or abstract; the scientific, or positive. In other terms, the human mind, by its nature, employs successively, in each of its researches, three methods of philosophizing, the character of which is essentially different, and even radically opposed; at first the theologic method, then the metaphysical, and last the positive method. Hence three distinct philosophies, or general systems of conceptions on the aggregate of phenomena, which mutually exclude each other; the first is the necessary starting-point of the human intelligence; the third is its fixed and definite state; the second is destined to serve the purpose only of transition.

"In the theologic state, the human mind, directing its researches to the intimate nature of things, the first causes and the final causes of all those effects which arrest its attention, in a word, towards an absolute knowledge of things, represents to itself the phenomena as produced by the direct and continuous action of supernatural agents, more or less numerous, whose arbitrary intervention explains all the apparent anomalies of the universe.
