THE innumerable groups of mankind, massed together or scattered, according to the varying nature of the earth’s surface, are far from presenting a homogeneous picture. Every country has its own variety of physical type, language, manners, and customs. Thus, in order to exhibit a systematic view of all the peoples of the earth, it is necessary to observe a certain order in the study of these varieties, and to define carefully what is meant by such and such a descriptive term, having reference either to the physical type or to the social life of men. This we shall do in the subsequent chapters as we proceed to develop this slight sketch of the chief general facts of the physical and psychical life of man, and of the most striking social phenomena of the groups of mankind. But there are some general terms which are of more importance than others, and their meaning should be clearly understood from the first. I refer to expressions like “people,” “nation,” “tribe,” “race,” “species,” in short, all the designations of the different groupings, real or theoretic, of human beings. Having defined them, we shall by so doing define the object of our studies. Since ethnography and anthropology began to exist as sciences, an attempt has been made to determine and establish the great groups amongst which humanity might be divided. A considerable diversity of opinion, however, exists among leading scientific men not only as to the number of these groups, of these “primordial divisions” of the human race, but, above all, as to the very nature of these groups. Their significance, most frequently, is very vaguely indicated. In zoology, when we proceed to classify, we have to do with beings which, in spite of slight individual differences, are easily grouped around a certain number of types, with well-defined characters, called “species.” An animal can always be found which will represent the “type” of its species. In all the great zoological collections there exist these “species-types,” to which individuals may be compared in order to decide if they belong to the supposed species. We have then in zoology a real substratum for the determination of species, those primordial units which are grouped afterwards in genera, families, orders, etc.
