Introduction to the Science of Sociology.

by Robert E. Park and Ernest W. Burgess.

PREFACE

The materials upon which this book is based have been collected from a wide range of sources and represent the observation and reflection of men who have seen life from very different points of view. This was necessary in order to bring into the perspective of a single volume the whole wide range of social organization and human life which is the subject-matter of a science of society.

At the same time an effort has been made to bring this material within the limits of a very definite series of sociological conceptions which suggest, at any rate, where they do not clearly exhibit, the fundamental relations of the parts to one another and to the concepts and contents of the volume as a whole.

The _Introduction to the Science of Sociology_ is not conceived as a mere collection of materials, however, but as a systematic treatise. On the other hand, the excerpts which make up the body of the book are not to be regarded as mere ill.u.s.trations. In the context in which they appear, and with the headings which indicate their place in the volume, they should enable the student to formulate for himself the principles involved. An experience of some years, during which this book has been in preparation, has demonstrated the value to the teacher of a body of materials that are interesting in themselves and that appeal to the experience of the student. If students are invited to take an active part in the task of interpretation of the text, if they are encouraged to use the references in order to extend their knowledge of the subject-matter and to check and supplement cla.s.sroom discussion by their personal observation, their whole att.i.tude becomes active rather than pa.s.sive. Students gain in this way a sense of dealing at first hand with a subject-matter that is alive and with a science that is in the making.

Under these conditions sociology becomes a common enterprise in which all members of the cla.s.s partic.i.p.ate; to which, by their observation and investigation, they can and should make contributions.

The first thing that students in sociology need to learn is to observe and record their own observations; to read, and then to select and record the materials which are the fruits of their readings; to organize and use, in short, their own experience. The whole organization of this volume may be taken as an ill.u.s.tration of a method, at once tentative and experimental, for the collection, cla.s.sification, and interpretation of materials, and should be used by students from the very outset in all their reading and study.

Social questions have been endlessly discussed, and it is important that they should be. What the student needs to learn, however, is how to get facts rather than formulate opinions. The most important facts that sociologists have to deal with are opinions (att.i.tudes and sentiments), but until students learn to deal with opinions as the biologists deal with organisms, that is, to dissect them--reduce them to their component elements, describe them, and define the situation (environment) to which they are a response--we must not expect very great progress in sociological science.

It will be noticed that every single chapter, except the first, falls naturally into four parts; (1) the introduction, (2) the materials, (3) investigations and problems, and (4) bibliography. The first two parts of each chapter are intended to raise questions rather than to answer them. The last two, on the other hand, should outline or suggest problems for further study. The bibliographies have been selected mainly to exhibit the recognized points of view with regard to the questions raised, and to suggest the practical problems that grow out of, and are related to, the subject of the chapter as a whole.

The bibliographies, which accompany the chapters, it needs to be said, are intended to be representative rather than authoritative or complete.

An attempt has been made to bring together literature that would exhibit the range, the divergence, the distinctive character of the writings and points of view upon a single topic. The results are naturally subject to criticism and revision.

A word should be said in regard to chapter i. It seemed necessary and important, in view of the general vagueness and uncertainty in regard to the place of sociology among the sciences and its relation to the other social sciences, particularly to history, to state somewhere, clearly and definitely, what, from the point of view of this volume, sociology is. This resulted finally in the imposition of a rather formidable essay upon what is in other respects, we trust, a relatively concrete and intelligible book. Under these circ.u.mstances we suggest that, unless the reader is specially interested in the matter, he begin with the chapter on "Human Nature," and read the first chapter last.

The editors desire to express their indebtedness to Dr. W. I. Thomas for the point of view and the scheme of organization of materials which have been largely adopted in this book.[1] They are also under obligations to their colleagues, Professor Albion W. Small, Professor Ellsworth Faris, and Professor Leon C. Marshall, for constant stimulus, encouragement, and a.s.sistance. They wish to acknowledge the co-operation and the courtesy of their publishers, all the more appreciated because of the difficult technical task involved in the preparation of this volume. In preparing copy for publication and in reading proof, invaluable service was rendered by Miss Roberta Burgess.

Finally the editors are bound to express their indebtedness to the writers and publishers who have granted their permission to use the materials from which this volume has been put together. Without the use of these materials it would not have been possible to exhibit the many and varied types of observation and reflection which have contributed to present-day knowledge of social life. In order to give this volume a systematic character it has been necessary to tear these excerpts from their contexts and to put them, sometimes, into strange categories. In doing this it will no doubt have happened that some false impressions have been created. This was perhaps inevitable and to be expected. On the other hand these brief excerpts offered here will serve, it is hoped, as an introduction to the works from which they have been taken, and, together with the bibliographies which accompany them, will serve further to direct and stimulate the reading and research of students.

The co-operation of the following publishers, organizations and journals, in giving, by special arrangement, permission to use selections from copyright material, was therefore distinctly appreciated by the editors:

CHAPTER I

SOCIOLOGY AND THE SOCIAL SCIENCES[2]

I. SOCIOLOGY AND "SCIENTIFIC" HISTORY

Sociology first gained recognition as an independent science with the publication, between 1830 and 1842, of Auguste Comte's _Cours de philosophie positive_. Comte did not, to be sure, create sociology. He did give it a name, a program, and a place among the sciences.

Comte's program for the new science proposed an extension to politics and to history of the positive methods of the natural sciences. Its practical aim was to establish government on the secure foundation of an exact science and give to the predictions of history something of the precision of mathematical formulae.

We have to contemplate social phenomena as susceptible of prevision, like all other cla.s.ses, within the limits of exactness compatible with their higher complexity.

Comprehending the three characteristics of political science which we have been examining, prevision of social phenomena supposes, first, that we have abandoned the region of metaphysical idealities, to a.s.sume the ground of observed realities by a systematic subordination of imagination to observation; secondly, that political conceptions have ceased to be absolute, and have become relative to the variable state of civilization, so that theories, following the natural course of facts, may admit of our foreseeing them; and, thirdly, that permanent political action is limited by determinate laws, since, if social events were always exposed to disturbance by the accidental intervention of the legislator, human or divine, no scientific prevision of them would be possible. Thus, we may concentrate the conditions of the spirit of positive social philosophy on this one great attribute of scientific prevision.[3]

Comte proposed, in short, to make government a technical science and politics a profession. He looked forward to a time when legislation, based on a scientific study of human nature, would a.s.sume the character of natural law. The earlier and more elementary sciences, particularly physics and chemistry, had given man control over external nature; the last science, sociology, was to give man control over himself.

Men were long in learning that Man's power of modifying phenomena can result only from his knowledge of their natural laws; and in the infancy of each science, they believed themselves able to exert an unbounded influence over the phenomena of that science.... Social phenomena are, of course, from their extreme complexity, the last to be freed from this pretension: but it is therefore only the more necessary to remember that the pretension existed with regard to all the rest, in their earliest stage, and to antic.i.p.ate therefore that social science will, in its turn, be emanc.i.p.ated from the delusion.... It [the existing social science] represents the social action of Man to be indefinite and arbitrary, as was once thought in regard to biological, chemical, physical, and even astronomical phenomena, in the earlier stages of their respective sciences.... The human race finds itself delivered over, without logical protection, to the ill-regulated experimentation of the various political schools, each one of which strives to set up, for all future time, its own immutable type of government. We have seen what are the chaotic results of such a strife; and we shall find that there is no chance of order and agreement but in subjecting social phenomena, like all others, to invariable natural laws, which shall, as a whole, prescribe for each period, with entire certainty, the limits and character of political action: in other words, introducing into the study of social phenomena the same positive spirit which has regenerated every other branch of human speculation.[4]

In the present anarchy of political opinion and parties, changes in the existing social order inevitably a.s.sume, he urged, the character, at the best, of a mere groping empiricism; at the worst, of a social convulsion like that of the French Revolution. Under the direction of a positive, in place of a speculative or, as Comte would have said, metaphysical science of society, progress must a.s.sume the character of an orderly march.

It was to be expected, with the extension of exact methods of investigation to other fields of knowledge, that the study of man and of society would become, or seek to become, scientific in the sense in which that word is used in the natural sciences. It is interesting, in this connection, that Comte's first name for sociology was _social physics_. It was not until he had reached the fourth volume of his _Positive Philosophy_ that the word sociological is used for the first time.

Comte, if he was foremost, was not first in the search for a positive science of society, which would give man that control over men that he had over external nature. Montesquieu, in his _The Spirit of Laws_, first published in 1747, had distinguished in the organization of society, between form, "the particular structure," and the forces, "the human pa.s.sions which set it in motion." In his preface to this first epoch-making essay in what Freeman calls "comparative politics,"

Montesquieu suggests that the uniformities, which he discovered beneath the wide variety of positive law, were contributions not merely to a science of law, but to a science of mankind.

I have first of all considered mankind; and the result of my thoughts has been, that amidst such an infinite diversity of laws and manners, they are not solely conducted by the caprice of fancy.[5]

Hume, likewise, put politics among the natural sciences.[6] Condorcet wanted to make history positive.[7] But there were, in the period between 1815 and 1840 in France, conditions which made the need of a new science of politics peculiarly urgent. The Revolution had failed and the political philosophy, which had directed and justified it, was bankrupt.

France, between 1789 and 1815, had adopted, tried, and rejected no less than ten different const.i.tutions. But during this period, as Saint-Simon noted, society, and the human beings who compose society, had not changed. It was evident that government was not, in any such sense as the philosophers had a.s.sumed, a mere artefact and legislative construction. Civilization, as Saint-Simon conceived it, was a part of nature. Social change was part of the whole cosmic process. He proposed, therefore, to make politics a science as positive as physics. The subject-matter of political science, as he conceived it, was not so much political forms as social conditions. History had been literature.

It was destined to become a science.[8]

Comte called himself Saint-Simon's pupil. It is perhaps more correct to say Saint-Simon formulated the problem for which Comte, in his _Positive Philosophy_, sought a solution. It was Comte's notion that with the arrival of sociology the distinction which had so long existed, and still exists, between philosophy, in which men define their wishes, and natural science, in which they describe the existing order of nature, would disappear. In that case ideals would be defined in terms of reality, and the tragic difference between what men want and what is possible would be effaced. Comte's error was to mistake a theory of progress for progress itself. It is certainly true that as men learn what is, they will adjust their ideals to what is possible. But knowledge grows slowly.

Man's knowledge of mankind has increased greatly since 1842. Sociology, "the positive science of humanity," has moved steadily forward in the direction that Comte's program indicated, but it has not yet replaced history. Historians are still looking for methods of investigation which will make history "scientific."

No one who has watched the course of history during the last generation can have felt doubt of its tendency. Those of us who read Buckle's first volume when it appeared in 1857, and almost immediately afterwards, in 1859, read the _Origin of Species_ and felt the violent impulse which Darwin gave to the study of natural laws, never doubted that historians would follow until they had exhausted every possible hypothesis to create a science of history. Year after year pa.s.sed, and little progress has been made. Perhaps the ma.s.s of students are more skeptical now than they were thirty years ago of the possibility that such a science can be created. Yet almost every successful historian has been busy with it, adding here a new a.n.a.lysis, a new generalization there; a clear and definite connection where before the rupture of idea was absolute; and, above all, extending the field of study until it shall include all races, all countries, and all times. Like other branches of science, history is now enc.u.mbered and hampered by its own ma.s.s, but its tendency is always the same, and cannot be other than what it is. That the effort to make history a science may fail is possible, and perhaps probable; but that it should cease, unless for reasons that would cause all science to cease, is not within the range of experience. Historians will not, and even if they would they can not, abandon the attempt. Science itself would admit its own failure if it admitted that man, the most important of all its subjects, could not be brought within its range.[9]

Since Comte gave the new science of humanity a name and a point of view, the area of historical investigation has vastly widened and a number of new social sciences have come into existence--ethnology, archaeology, folklore, the comparative studies of cultural materials, i.e., language, mythology, religion, and law, and in connection with and closely related with these, folk-psychology, social psychology, and the psychology of crowds, which latter is, perhaps, the forerunner of a wider and more elaborate political psychology. The historians have been very much concerned with these new bodies of materials and with the new points of view which they have introduced into the study of man and of society.

Under the influences of these sciences, history itself, as James Harvey Robinson has pointed out, has had a history. But with the innovations which the new history has introduced or attempted to introduce, it does not appear that there have been any fundamental changes in method or ideology in the science itself.

Fifty years have elapsed since Buckle's book appeared, and I know of no historian who would venture to maintain that we had made any considerable advance toward the goal he set for himself. A systematic prosecution of the various branches of social science, especially political economy, sociology, anthropology, and psychology, is succeeding in explaining many things; but history must always remain, from the standpoint of the astronomer, physicist, or chemist, a highly inexact and fragmentary body of knowledge.... History can no doubt be pursued in a strictly scientific spirit, but the data we possess in regard to the past of mankind are not of a nature to lend themselves to organization into an exact science, although, as we shall see, they may yield truths of vital importance.[10]

History has not become, as Comte believed it must, an exact science, and sociology has not taken its place in the social sciences. It is important, however, for understanding the mutations which have taken place in sociology since Comte to remember that it had its origin in an effort to make history exact. This, with, to be sure, considerable modifications, is still, as we shall see, an ambition of the science.

II. HISTORICAL AND SOCIOLOGICAL FACTS

Sociology, as Comte conceived it, was not, as it has been characterized, "a highly important point of view," but a fundamental science, i.e., a method of investigation and "a body of discoveries about mankind."[11]

In the hierarchy of the sciences, sociology, the last in time, was first in importance. The order was as follows: mathematics, astronomy, physics, chemistry, biology including psychology, sociology. This order represented a progression from the more elementary to the more complex.

It was because history and politics were concerned with the most complex of natural phenomena that they were the last to achieve what Comte called the positive character. They did this in sociology.

Many attempts have been made before and since Comte to find a satisfactory cla.s.sification of the sciences. The order and relation of the sciences is still, in fact, one of the cardinal problems of philosophy. In recent years the notion has gained recognition that the difference between history and the natural sciences is not one of degree, but of kind; not of subject-matter merely, but of method. This difference in method is, however, fundamental. It is a difference not merely in the interpretation but in the _logical character_ of facts.

Every historical fact, it is pointed out, is concerned with a unique event. History never repeats itself. If nothing else, the mere circ.u.mstance that every event has a _date_ and _location_ would give historical facts an individuality that facts of the abstract sciences do not possess. Because historical facts always are located and dated, and cannot therefore be repeated, they are not subject to experiment and verification. On the other hand, a fact not subject to verification is not a fact for natural science. History, as distinguished from natural history, deals with individuals, i.e., individual events, persons, inst.i.tutions. Natural science is concerned, not with individuals, but with cla.s.ses, types, species. All the a.s.sertions that are valid for natural science concern cla.s.ses. An ill.u.s.tration will make this distinction clear.

Sometime in October, 1838, Charles Darwin happened to pick up and read Malthus' book on _Population_. The facts of "the struggle for existence," so strikingly presented in that now celebrated volume, suggested an explanation of a problem which had long interested and puzzled him, namely, the origin of species.

This is a statement of a historical fact, and the point is that it is not subject to empirical verification. It cannot be stated, in other words, in the form of a hypothesis, which further observation of other men of the same type will either verify or discredit.

On the other hand, in his _Descent of Man_, Darwin, discussing the role of s.e.xual selection in evolution of the species, makes this observation: "Naturalists are much divided with respect to the object of the singing of birds. Few more careful observers ever lived than Montagu, and he maintained that the 'males of songbirds and of many others do not in general search for the female, but, on the contrary, their business in spring is to perch on some conspicuous spot, breathing out their full and amorous notes, which, by instinct, the female knows and repairs to the spot to choose her mate.'"

This is a typical statement of a fact of natural history. It is not, however, the rather vague generality of the statement that makes it scientific. It is its representative character, the character which makes it possible of verification by further observation which makes it a scientific fact.

It is from facts of this kind, collected, compared, and cla.s.sified, irrespective of time or place, that the more general conclusions are drawn, upon which Darwin based his theory of the "descent of man." This theory, as Darwin conceived it, was not an _interpretation_ of the facts but an _explanation_.
