When we consider our problem from a purely psychological point of view, we have to follow out the same lines of thought which we pursued in our discussion of the anatomical problem. We must try to enumerate clearly the typical differences between the human mind and the animal mind, which must serve as the background of our discussions. In the treatment of the psychic differences between civilized man and primitive man, we must distinguish the two problems of differences in cultural state of members of the same race, and differences in characteristics of different races; in other words, the problems of environmental influences and of influences of heredity.
For the purposes of our investigation, we do not need to enter deeply into a discussion of the first-named problem, the differences between the minds of the animal and of man. The differences are so striking that little or no diversity of opinion exists. The two outer traits in which the distinction between the minds of animal and of man finds expression are the existence of organized articulate language in man, and the use of utensils of varied application. Both of these are common to the whole of mankind. No tribe has ever been found that does not possess a well-organized language; no community that does not know the use of instruments for breaking, cutting, or drilling, the use of fire and of weapons with which to defend themselves and to obtain the means of living. Although means of communication by sound exist in animals, and although even lower animals seem to have means of bringing about co-operation between different individuals, we do not know of any case of true articulate language from which the student can extract abstract principles of classification of ideas. It may also be that higher apes employ now and then limbs of trees or stones for defence, but the use of complex utensils is not found in any representative of the animal series. Only in the case of habitations do we find an approach to more complex activities, which, however, remain absolutely stable in each species,—as we say, instinctive,—and bear no evidence of any individual freedom of use, which constitutes the primary character of human inventions. The origin of the instinctive activities of animals which lead to the construction of complex mechanical devices is still a hidden secret; but the relation of the individual of the species to these activities differs from that of man to his inventions in the complete lack of freedom of control.
We are accustomed to say that the essential characteristic of the mental processes of man is the power of reasoning. While animals as well as man may perform actions suited to an end, based on memory of the results of previous actions, and suitable selection of actions fitting a certain purpose, we have no evidence whatever that would show that the abstract concepts accompanying the action can be isolated by animals, while all groups of man, from the most primitive to the most highly developed, possess this faculty.
These few remarks on the common mental traits of man will suffice. When we turn to a consideration of the racial and social characteristics of the human mind, we find ourselves confronted by a peculiar difficulty. In all our thoughts we think in terms of our own social environment. But the activities of the human mind exhibit an infinite variety of form among the peoples of the world. In order to understand these clearly, the student must endeavor to divest himself entirely of opinions and emotions based upon the peculiar social environment into which he is born. He must adapt his own mind, so far as feasible, to that of the people whom he is studying. The more successful he is in freeing himself from the bias based on the group of ideas that constitute the civilization in which he lives, the more successful he will be in interpreting the beliefs and actions of man. He must follow lines of thought that are new to him. He must participate in new emotions, and understand how, under unwonted conditions, both lead to actions. Beliefs, customs, and the response of the individual to the events of daily life, give us ample opportunity to observe the manifestations of the mind of man under varying conditions.
Apparently the thoughts and actions of civilized man, and those found in more primitive forms of society, prove, that, in various groups of mankind, the mind responds quite differently when exposed to the same conditions. Lack of logical connection in its conclusions, lack of control of will, are apparently two of its fundamental characteristics in primitive society. In the formation of opinions, belief takes the place of logical demonstration. The emotional value of opinions is great, and consequently they quickly lead to action. The will appears unbalanced, there being a readiness to yield to strong emotions and a stubborn resistance in trifling matters.
Unfortunately the descriptions of the state of mind of primitive people, such as are given by most travellers, are too superficial to be used for psychological investigation. Very few travellers understand the language of the people they visit; and how is it possible to judge a tribe solely by the descriptions of interpreters, or by observations of disconnected actions the incentive of which remains unknown? But even when the language of the people is known to the visitor, he is generally an unappreciative listener to their tales. The missionary has his strong bias against the religious ideas and customs of primitive people, and the trader has no interest in their beliefs and in their barbarous arts. The observers who seriously tried to enter into the inner life of a people, the Cushings, Callaways, and Greys, are few in number, and may be counted on one’s fingers. Nevertheless the bulk of the argument is always based on the statements of hasty and superficial observers.
Numerous attempts have been made to describe the peculiar psychological characteristics of primitive man. Among these I would mention those of Klemm, Carus, De Gobineau, Nott and Gliddon, Waitz, Spencer, and Tylor. Their investigations are of merit as descriptions of the characteristics of primitive people, but we cannot claim for any of them that they describe the psychological characters of races independent of their social surroundings. Klemm and Wuttke designate the civilized races as active, all others as passive, and assume that all elements and beginnings of civilization found among primitive people—in America or on the islands of the Pacific Ocean—were due to an early contact with civilization. Carus divides mankind into “peoples of the day, night and dawn.” De Gobineau calls the yellow race the male element, the black race the female element, and calls only the whites the noble and gifted race. Nott and Gliddon ascribe animal instincts only to the lower races, while they declare that the white race has a higher instinct which incites and directs its development.
The belief in the higher hereditary powers of the white race has gained a new life with the modern doctrine of the prerogatives of the master-mind, which have found their boldest expression in Nietzsche’s writings.
All such views are generalizations which either do not sufficiently take into account the social conditions of races, and thus confound cause and effect, or were dictated by scientific or humanitarian bias, by the desire to justify the institution of slavery, or to give the greatest freedom to the most highly gifted.
Tylor and Spencer, who give an ingenious analysis of the mental life of primitive man, do not assume that these are racial characteristics, although the evolutionary standpoint of Spencer’s work often seems to convey this impression.
