knowledge have passed through the three stages of progress at different rates, and have not therefore arrived at the same time. The rate of advance depends on the nature of the knowledge in question, so distinctly that, as we shall see hereafter, this consideration constitutes an accessory to the fundamental law of progress. Any kind of knowledge reaches the positive stage early in proportion to its gene- rality, simplicity, and independence of other departments.
NEW PROVINCE OF POSITIVE PHILOSOPHY. 7 Astronomical science, wliicli is above all made np of facts tliat are general, simple, and independent of other sciences, arrived first; then terrestrial Physics; then Chemistry; and, at length, Physiology.
It is difficult to assign any precise date to this revolution in science. It may be said, like everything else, to have been alvrays going on; and especially since the labours of Aristotle and the school of Alexandria; and then from the introdiiction of natural science into the West of Europe by the Arabs. But, if we must fix upon some marked period, to serve as a rallying point, it must be that, — about tvro centuries ago, — when the human mind was astir under the precepts of Bacon, the conceptions of Descartes, and the discoveries of Galileo. Then it was that the spirit of the Positive philosophy rose \vp in opposition to that of the superstitious and scholastic systems which had hitherto obscured the true character of all science. Since that date, the progress of the Positive philosophy, and the decline of the other two, have been so marked that no rational mind now doubts that the revolution is destined to go on to its completion, ^every branch of knowledge being, sooner or later, brought within the operation of Positive philosophy. This is not yet the case. Some are still lying outside: and- not till they are brought in will the Positive philosophy possess that character of universality which is necessary to its definitive constitution.
In mentioning just now the four principal categories of phenomena, — astronomical, physical, chemical, and jjhysio- logical, — there was an omission which will have been noticed. Nothing was said of Social pheno- ]s[ew depart- mena. Though involved with the physio- ment of Posi- logical. Social phenomena demand a distinct ^ive philoso- elassification, both on account of their im- 1' ^^' portance and of tbeir difficulty. They are the most indi- vidual, the most complicated, the most dependent on all others; and therefore they must be the latest, — even if they had no special obstacle to encounter. This branch of ^ science has not hitherto entered into the domain of Positive, philosophy. Theological and metaphysical methods, ex- ■ ploded in other departments, are as yet exclusively applied, both in the way of inquiry and discussion, in all treatment 8 POSITIVE PHILOSOPHY.
of Social subjects, though the best minds are heartily weary of eternal disputes about divine right and the sove- reignty of the people. This is the great, while it is evidently the only gap which has to be filled, to constitute, solid and entire, the Positive Philosophy. Now that the human mind has grasped celestial and terrestrial physics, — mechanical and chemical; organic physics, both vege- table and animal, — there remains one science, to fill up the series of sciences of observation, — Social physics. This is what men have now most need of: and this it is the principal aim of the jDresent work to establish.
r, • 1 Til • It would be absurd to pretend to offer this Social Physics..,. ^ i,,, new science at once m a complete state.
Others, less new, are in very unequal conditions of forward- ness. But the same character of positivity which is im- pressed on all the others will be shown to belong to this. This once done, the philosophical system of the moderns will be in fact complete, as there will then be no pheno- menon which does not naturally enter into some one of the five great categories. All our fundamental conceptions having become homogeneous, the Positive state will be fully established. It can never again change its character, though it will be for ever in course of development by additions of new knowledge. Having acquired the character of universality which has hitherto been the only advantage resting with the two preceding systems, it will supersede them by its natural supeinority, and leave to them only an historical existence.
„,. We have stated the special aim of this of this work "work. Its secondary and general aim is this: — to review what has been effected in the Sciences, in order to show that they are not radically separate, but all branches from the same trunk. If we had confined ourselves to the first and special object of the work, we should have produced merely a study of Social physics: whereas, in introducing the second and general, we offer a study of Positive philosophy, passing in review all the positive sciences already formed.
To review the ^^^ jDurpose of this work is not to give au Ijhik)sophy of account of the Natural Sciences. Besides tlie Sciences, that it would be endless, and that it would DESULTORY DIVISION OF RESEARCH. 9 require a scientific preparation sucli as no one man possesses, it would be ajiart from our object, which is to go through a course of not Positive Science, but Positive Philosophy. We have only to consider each fundamental science in its relation to the whole'positive system, and to the spirit which characterizes it; that is, with regard to its methods and its chief results.
The two aims, though distinct, are inseparable; for, on the one hand, there can be no positive jjliilosophy without a basis of social science, without which it could not be all- comprehensive; and, on the other hand, we could not pursue Social science without having been prepared by the study of phenomena less complicated than those of society, and furnished with a knowledge of laws and anterior facts which have a bearing upon social science. Though the fundamental sciences are not all equally interesting to ordinary minds, there is no one of them that can be neglected in an inquiry like the pi'esent; and, in the eye of philosophy, all are of equal value to human welfare. Even those which appear the least interesting have their own value, either on account of the perfection of their methods, or as being the necessary basis of all the others.
Lest it should be suY>posed that our course ^ p„j„i;*., will lead us into a wilderness of such special studies as are at present the bane of a true positive philo- sophy, we will briefly advert to the existing prevalence of such special pursuit. In the primitive state of human knowledge there is no regular division of intellectual labour. Every student cultivates all the sciences. As knowledge accrues, the sciences part off; and students de- vote themselves each to some one branch. It is owing to this division of employment, and concentration of whole minds upon a single department, that science has made so pro- digious an advance in modern times; and the perfection of this division is one of the most important characteristics of the Positive philosophy. But, while admitting all the merits of this change, we cannot be blind to the eminent disadvantages which arise from the limitation of minds to a particidar study. It is inevitable that each should be possessed with exclusive notions, and be thei'efore in- capable of the general superiority of ancient students.
10 POSITIVE PHILOSOPHY.
who actually owed that general superiority to the in- feriority of their knowledge. We must consider whether the evil can be avoided without losing the good of the modern arrangement; for the evil is becoming urgent. We all acknowledge that the divisions established for the convenience of scientific pursuit are radically artificial; and yet there are very few who can embrace in idea the whole of any one science: each science moreover being itself only a part of a great whole. Almost every one is busy about his own particular section, without much thought about its relation to the general system of positive knowledge. We must not be blind to the evil, nor slow in seeking a remedy. We must not forget that this is the weak side of the posi- tive philosophy, by which it may yet be attacked, with some hope of success, by the adherents of the theological and metaphysical systems. As to the remedy, it certainly does not lie in a return to the ancient confusion of pursuits, which would be mere retrogression, if it were possible, which it is not. It lies in perfecting the division of em- ployments itself, — in carrying it one degree higher,- — in constituting one more speciality from the study of scientific generalities. Let us have a new class of students, suitably Proposed new prepared, whose business it shall be to take class of stu- the respective sciences as they are, determine dents. i\^Q sjjirit of each, ascertain their relations and mutual connection, and reduce their respective princi- ples to the smallest number of general principles, in con- formity with the fundamental rules of the Positive Method. At the same time, let other students be j)rei3ared for their special pursuit by an education which recognizes the whole scope of positive science, so as to profit by the labours of the students of generalities, and so as to correct recipro- cally, under that guidance, the residts obtained by each. We see some aj^proach already to this arrangement. Once established, there would be nothing to apprehend from any extent of division of employments. When we once have a class of learned men, at the disposal of all others, whose business it shall be to connect each new discovery with the general system, we may dismiss all fear of the great whole being lost sight of in the pursuit of the details of know- ledge. The organization of scientific research will then be FIRST BENEFIT. 11 FIRST BENEFIT. 11 complete; and it will henceforth have occasion only to ex- tend its development, and not to change its character. After all, the formation of such a new class as is proposed would be merely an extension of the principle which has created all the classes we have. While science was narrow, there was only one class: as it expanded, more were insti- tuted. With a further advance a fresh need arises, and this new class will be the result.
The general spirit of a course of Positive Advantages of Philosophy having been thus set forth, we the Po.sitive must now glance at the chief advantages t*liilosopliy. which may be derived, on behalf of human progression, from the study of it. Of these advantages, four may be especially pointed out.
I. The study of the Positive Philosophy lllnstratesthe affords the only rational means of exhibiting Intellectual thelogical laws of the human mind, which have function, hitherto been sought by unfit methods. To explain what is meant by this, we may refer to a saying of M. de Blain- ville, in his work on Comparative Anatomy, that every active, and especially every living being, may be regarded under two relations — the Statical and the Dynamical; that is, under conditions or in action. It is clear that all con- siderations range themselves under the one or the other of these heads. Let us apply this classification to the intel- lectual functions.
If we regard these functions under their Statical aspect — that is, if we consider the conditions under which they ■exist — we must determine the organic circumstances of the case, which inquiry involves it with anatomy and physiology. If we look at the Dynamic aspect, we have to study simply the exercise and results of the intellectual powers of the human race, which is neither more nor less than the general object of the Positive Philosophy. In short, looking at all scientific theories as so many great logical facts, it is only by the thorough observation of these facts that we can arrive at the knowledge of logical laws. These being the only means of knowledge of intellectual phenomena, the illusory psychology, which is the last phase of theology, is excluded. It pretends to accomplish the discovery of the laws of the human mind by contemplating it in itself; 12 POSITIVE PHILOSOPHY.
that is, by separating it from causes and effects. Such an attempt, made in defiance of the physiological study of our intellectual organs, and of the observation of rational methods of procedure, cannot succeed at this time of day.
The Positive Philosophy, which has been rising since the time of Bacon, has now secured such a preponderance, that the metaphysicians themselves profess to ground their pre- tended science on an observation of facts. They talk of ex- ternal and internal facts, and say that their business is with the latter. This is much like saying that vision is explained by luminous objects painting their images upon the retina. To this the physiologists reply that another eye woiild be needed to see the image. In the same manner, the mind may observe all phenomena but its own. It may be said that a man's intellect may observe his passions, the seat of the reason being somewhat apart from that of the emotions in the brain; but there can be nothing like scientific observation of the passions, except from, without, as the stir of the emotions disturbs the observ- ing faculties more or less. It is yet more out of the ques- tion to make an intellectual observation of intellectual processes. The observing and observed organ are here the same, and its action cannot be pure and natural. In order to observe, your intellect must j^ause from activity; yet it is this very activity that you want to observe. If you can- not effect the pause, you cannot observe: if you do effect it, there is nothing to observe. The results of such a method are in proportion to its absurdity. After two thousand years of psychological jjursuit, no one proposition is established to the satisfaction of its followers. They are divided, to this day, into a multitude of schools, still dis- jjuting about the very elements of their doctrine. This in- terior observation gives birth to almost as many theories as there are observers. We ask in vain for any one discovery, great or small, which has been made under this method. The psychologists have done some good in keeping up the activity of our understandings, when there was no better work for our faculties to do; and they may have added something to our stock of knowledge. If they have done so, it is by practising the Positive method — by observing SECOND BENEFIT. 13 the progress of tlie liuman mind in the light of science; that is, by ceasing, for the moment, to be psychologists.
The view just given in relation to logical Science becomes yet more striking when we consider the logical Art.
The Positive Method can be judged of only in action. It cannot be looked at by itself, apart from the work on which it is employed. At all events, such a contempla- tion would be only a dead study, which could produce nothing in the mind which loses time upon it. We may talk for ever about the method, and state it in terms very wisely, withoi:t knowing half so much about it as the man who has once j^ut it in practice ujDon a single particular of actual research, even without any philosophical intention. Thus it is that psychologists, by dint of reading the pre- cepts of Bacon and the discourses of Descartes, have mis- taken their own dreams for science.
Without saying whether it will ever be possible to estab- lish a priori a true method of investigation, independent of a philosophical study of the sciences, it is clear that the thing has never been done yet, and that we are not capable of doing it now. We cannot as yet explain the great logical procedures, apart from their ajiplications. If we ever do, it will remain as necessary then as now to form good intellectual habits by studying the regular application of the scientific methods which we shall have attained.
This, then, is the first great result of the Positive Philo- sophy— the mai^ifestation by experiment of the laws which rule the Intellect in the investigation of truth; and, as a consequence the knowledge of the general rules suitable for that object.
II. The second effect of the Positive Must re^ene- Philosophy, an effect not less important and late Educa- far more urgently wanted, will be to regene- *^'^"- rate Education.
The best minds are agreed that our European education, still essentially theological, metaphysical, and literary, must be superseded by a Positive training, conformable to our time and needs. Even the governments of our day have shared, where they have not originated, the attempts to establish positive instruction; and this is a striking in- 14 POSITIVE PHILOSOPHY.
dication of the prevalent sense of what is wanted. While encouraging such endeavours to the utmost, we must not however conceal from ourselves that everything yet done is inadequate to the object. The j^resent exclusive speciality of our pursuits, and the consequent isolation of the sciences, spoil our teaching. If any student desires to form an idea of natural philosophy as a whole, he is compelled to go through each department as it is now taught, as if he were to be only an astronomer, or only a chemist; so that, be his intellect what it may, his training must remain very imperfect. And yet his object requires that he should obtain general positive concej^tious of all the classes of natural phenomena. It is such an aggregate of concep- tions, whether on a great or on a small scale, which must henceforth be the permanent basis of all human combina- tions. It will constitute the mind of future generations. In order to this regeneration of our intellectual system, it is necesary that the sciences, considered as branches from one trunk, should yield us, as a whole, their chief methods and their most important results. The specialities of science can be pursued by those whose vocation lies in that direction. They are indispensable; and they are not likely to be neglected; but they can never of themselves renovate our system of Education; and, to be of their full use, they must rest upon the basis of that general instruction which is a direct result of the Positive Philosophy. Advances HI- The same special study of scientific sciences by generalities must also aid the progress of the combining respective positive sciences: and this consti- them. tutes our third head of advantages.
The divisions which we establish between the sciences are, though not arbitrary, essentially artificial. The sub- ject of our researches is one: we divide it for our con- venience, in order to deal the more easily with its difficul- ties. But it sometimes happens — -and especially with the most important doctrines of each science — that we need what we cannot obtain under the present isolation of the sciences, — a combination of sevei'al special points of view; and for want of this, very important problems wait for their solution much longer than they otherwise need do. To go back into the past for an examj)le: Descartes' grand THIRD AND FOURTH BENEFITS. 15 conception with regard to analytical geometry is a dis- covery which has changed the whole aspect of mathe- matical science, and yielded the germ of all future pro- gress; aud it issued from the union of two sciences which had always before been separately regai'ded and pursued. The case of pending questions is yet more impressive; as, for instance, in Chemistry, the doctrine of Definite Propor- tions. Without entering upon the discussion of the funda- mental principle of this theoxy, we may say with assurance that, in order to determine it — in order to determine whether it is a law of nature that atoms should necessarily combine in fixed numbers, — it will be indispensable that the chemical point of view should be united with the physiological. The failure of the theory with regard to organic bodies indicates that the cause of this immense exception must be investigated; and such an inquiry be- longs as much to physiology as to chemistry. Again, it is as yet undecided whether azote is a simj^le or a compound body. It was concluded by almost all chemists that azote is a simple body; the illustrious Berzelius liesitated, on purely chemical considerations; but he was also influenced by the physiological observation that animals which receive no azote in their food have as much of it in their tissues as carnivorous animals. From this we see how physiology must unite with chemistry to inform us whether azote is simple or compound, and to institute a new series of re- searches upon the relation between the composition of living bodies and their mode of alimentation.
Such is the advantage which, in the third place, we shall owe to Positive philosophy — the elucidation of the respec- tive sciences by their combination. In the fourth place IV. The Positive Philosophy offers the only solid basis for that Social Reorganiza- „^,j.\.^„;„(!;' ' tion which must succeed the critical condition in which the most civilized nations are now living.
It cannot be necessary to prove to anybody who reads this work that Ideas govern the world, or throw it into chaos; in other words, that all social mechanism rests upon Opinions. The great political and moral crisis that societies are now undergoing is shown by a rigid analysis to arise out of intellectual anarchy. While stability in funda- 16 - POSITIVE PHILOSOPHY.
mental maxims is the first condition of genuine social order, we are suffering under an utter disagreement which may be called universal. Till a certain number of general ideas can be acknowledged as a rallying-point of social doctrine, the nations will remain in a revolutionary state, whatever palliatives may be devised; and their institutions can be only provisional. But whenever the necessary agreement on first principles can be obtained, appropriate institutions will issue from them, without shock or resis- tance; for the causes of disorder will have been arrested by the mere fact of the agreement. It is in this direction that those must look who desire a natural and regular, a normal state of society.
Now, the existing disorder is abundantly accounted for by the existence, all at once, of three incompatible philo- sophies,— the theological, the metaphysical, and the posi- tive. Any one of these might alone secure some sort of social order; but while the three co-exist, it is impossible for us to understand one another upon any essential point whatever. If this is true, we have only to ascertain which of the philosophies must, in the nature of things, prevail; aud, this ascertained, every man, whatever may have been his former views, cannot but concur in its triumph. The problem once recognized cannot remain long unsolved; for all considerations whatever point to the Positive Philosophy as the one destined to prevail. It alone has been advancing during a course of centuries, throughout which the others have been declining. The fact is incontestable. Some may deplore it, but none can destroy it, nor therefore neglect it but under penalty of being betrayed by illusory speculations. This genei'al revolution of the human mind is nearly accomplished. We have only to complete the Positive Philosophy by bringing Social phenomena within its comprehension, and afterwards consolidating the whole into one body of homogeneous doctrine. The marked preference which almost all minds, from the highest to the commonest, accord to positive knowledge over vague and mystical conceptions, is a pledge of what the reception of this philosophy will be when it has acquired the only quality that it now wants — a character of due generality. When it has become complete, its supremacy will take PRECAUTIONARY OBSERVATION. 17 place spontaneously, and will re-establisli order throughout society. There is, at present, no conflict but between the theological and the metaphysical philosophies. They are contending for the task of reorganizing society; but it is a work too mighty for either of them. The positive philo- sophy has hitherto intervened only to examine both, and both are abuudaiitly discredited by the process. It is time now to be doing something more effective, without wasting our forces in needless controversy. It is time to complete the vast intellectual operation begun by Bacon, Descartes, and Galileo, by constructing the system of general ideas which must henceforth j^revail among the human race. This is the way to put an end to the revolu- tionary crisis which is tormenting the civilized nations of the world.
Leaving these four points of advantage, we must attend to one precautionary reflection.
Because it is proposed to consolidate the No hope of re- whole of our acquired knowledge into one chiction to a body of homogeneous doctrine, it must not single law. be supposed that we are going to study this vast variety as proceeding from a single principle, and as subjected to a single law. There is something so chimerical in attempts at universal explanation by a single law, that it may be as Avell to secure this Work at once from any imputation of the kind, though its development will show how lui deserved such an imputation would be. Our intellectual resources are too narrow, and the universe is too complex, to leave any hope that it will ever be within our power to carry scientific perfection to its last degree of simplicity. More- over, it appears as if the value of such an attainment, sup- posing it possible, were greatly overrated. The only way, for instance, in which we could achieve the business, would be by connecting all natural phenomena with the most general law we know,^ — which is that of Gravitation, by which astronomical phenomena are already connected witli a portion of terrestrial physics. Laplace has indicated that chemical phenomena may be regarded as simple atomic effects of the Newtonian attraction, modified by
