Introduction to the Science of Sociology

by Robert Ezra Park; E. W. Burgess

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 classification 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 circumstance 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, institutions. Natural science is concerned, not with individuals, but with classes, types, species. All the assertions that are valid for natural science concern classes. An illustration 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 rôle of sexual 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 classified, 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.

The relation between history and sociology, as well as the manner in which the more abstract social sciences have risen out of the more concrete, may be illustrated by a comparison between history and geography. Geography as a science is concerned with the visible world, the earth, its location in space, the distribution of the land masses, and of the plants, animals, and peoples upon its surface. The order, at least the fundamental order, which it seeks and finds among the objects it investigates is spatial. As soon as the geographer begins to compare and classify the plants, the animals, and the peoples with which he comes in contact, geography passes over into the special sciences, i.e., botany, zoölogy, and anthropology.
