These effects, which we ourselves experience and which we see produced upon other individuals on passing from one climate to another, we seem to see impressed upon many of the races which have long been subjected to these climates; for example, the slow and lazy Malays have long occupied the hottest moistest region of the earth. The Arabs and the fiery Sikhs may be held to illustrate the effect of dry heat. The Englishman and the Dutchman seem to show the effects of a moist cool climate, a certain sluggishness embodied with great energy and perseverance.

In these and other cases, in which the innate temperament of a people corresponds to the effects directly induced by their climate, it seems natural to suppose that the innate temperament has been produced by the transmission and accumulation from generation to generation of the direct effects of the climate. The assumption is so natural that it has been made by almost every writer who has dealt with the question. And these instances of conformity of the temperament of peoples to the direct effects of climate are sometimes offered as being among the most striking evidences of the reality of hereditary transmission of acquired qualities; and the argument is reinforced by instances of what seem to be similar results produced by climate on physical types. Thus, it is said that in North America a race characterised by a new specific combination of mental and physical qualities is being rapidly formed; and it seems to be well established that long slender hands are among these features; for in Paris a specially long slender glove is made every year in large quantities for the American market. Again, we see apparently a change of physical type in the white inhabitants of Australia. They seem to be becoming taller and more slender ‘cornstalks’; and this is commonly regarded as the direct effect of climate.

Now, that a new race or subrace with a specific combination of qualities should be forming in America is certainly to be expected from the fact that the intimate blending of a number of European stocks has been going on for some generations. But what gives special support to the assumption that these new qualities are the direct effects of climate is that these qualities, the physical at least, seem to be approximations to the type of the Red Indians, the aboriginal inhabitants. And, it is said, this approximation of type can only be due to hereditary accumulation of the direct effects of the climate on individuals.

Another way in which climate has been held to modify racial mental qualities by direct action is through the senses, especially the eye. M. Boutmy, in his book on the English people makes great play with this principle[107]. He points out that the thick hazy state of the air, so common in our islands, renders vague and dull all outlines and colours, so that the eye does not receive that wealth of well-defined hues and forms which give so great a charm to some more sunny lands, such as the Mediterranean coast lands. Hence, he says, the senses become or remain relatively dull, and the sense-perceptions slow and relatively indiscriminating. Such relative deficiency of aesthetic variety and richness in the appearance of the outer world produces secondarily a further and deeper modification of mental type. In the lands where nature surrounds man with an endless variety of rich and pleasing scenes, he can find sufficient satisfaction in mere contemplation of the outer world; and, when he takes to art production, he tends merely to reproduce in more or less idealised forms the objects and scenes he finds around him; his art tends to be essentially objective. On the other hand, in the dull northern climes, man has not ever at hand these sources of satisfaction in the mere contemplation of the outer world; consequently he is driven back upon his own nature, to find his satisfactions in a ceaseless activity of mind and body, but chiefly of the latter. Hence, races so situated are characterised by great bodily activity and their art and literature are essentially subjective. The thick air, the monotony of vague form and colour, drive the mind to reflection upon itself; and in art the objects of nature serve merely as symbols by aid of which the mind seeks to express its own broodings. “The painter paints with the intentions of the poet, the poet describes or sings with the motives of the psychologist or moralist. All the literature of imagination of the English shows us the internal reacting incessantly upon the external with a singular power of transfiguration and interpretation[108].” Hence also poetry is the privilege of a few rare spirits and is for them the product of deep reflection, not a simple lyrical expression in which all can equally share.

It is certainly true that climate tends to produce these effects by its direct action on individuals. Anyone who has lived for a time in the southern climes must have noted these effects upon himself. But we have no proof that the effects of climate are directly inherited. It suffices to suppose that the direct effects are imposed afresh by the climate on the minds of each generation. This view is borne out by the fact that two races may live for many generations in the same climate and yet remain very different in temperament in these respects; for example the Irish climate is very similar to the English, perhaps even more misty and damp; yet the Irish have much more wit and liveliness than the English. And in every case in which adaptation to physical environment has clearly become innate or racial, an explanation can be suggested in terms of selection of spontaneous variations, or of crossing of races. Thus, the approximation of the American people to the type of the aboriginals, if it is actual, and some observers deny it, may well be due to the small infusion of the native blood which has admittedly taken place. It may well be that certain qualities of the Red Indian, for example, the straight dark hair and prominent cheek bones, are what the biologists call ‘dominant characters’ when the Indian is crossed with the European; that is, qualities which always assert themselves in the offspring, to the exclusion of the corresponding quality of the other race involved in the cross. If that is so, a very small proportion of Indian blood would suffice to make these features very common throughout the population of America. As an exception to the supposed law of direct hereditary adaptation to climate take the colour of the skin. The black negroes live in the hot moist regions of Africa, and it has been said that pigmentation is the hereditary effect of a hot moist climate. But there are men of a different race who have long lived in an equally hot and moist climate, but who do not show this effect—namely, tribes in the heart of Borneo, right under the equator, whose skins are hardly darker than the average English skins and less dark than the Southern Europeans’. Take again the indolence of the peoples of warm hot climates and the energy of peoples of colder climates. These certainly seem to be racial qualities; but their distribution is adequately explained by the indirect effect of physical environment exerted by way of natural selection; and these differences of energy afford the best illustration of such indirect action of physical environment in determining racial mental qualities.

Before considering the question further, let us note yet another way in which the physical environment affects men’s minds and has been supposed directly to induce certain racial qualities. Buckle pointed out with great force the influence on the mind of what he called the external aspects of nature. He showed that where, as in India and the greater part of Asia, the physical features of a country are planned upon a very large scale; where the mountains are huge, where rivers are of immense length and volume, where plains are of boundless extent, and the sun very hot, there the forces of nature are exerted with an intensity that renders futile the best efforts of man, at any rate of man in a state of low civilisation, to cope with them. In such countries men are exposed to calamities on an enormous scale, great floods, violent storms and deluges of rain, earthquakes, excessive droughts resulting in famine and plague; and they are exposed to the attacks of many dangerous animal species, which are bred by the great heat in the dense and unconquerable forests. These disasters have repeatedly occurred on a scale such that in comparison with them the recent earthquake in California appears a mere trifle. Millions have been destroyed in a few hours in some of the floods of the Yellow River of China.

The magnitude of these objects and the appalling and irresistible character of such devastating forces produce, said Buckle, two principal and closely allied effects upon the mind; they stimulate the imagination to run riot in extravagant and grotesque fancies; at the same time, they discourage any attempt to cope with these great forces and to understand their laws, and thus keep men perpetually in fearful uncertainty as to their fate; for they cannot hope to control it by their own unaided efforts.

Hence, the encouragement of superstition; hence, the dominance of a degrading religion of fear throughout the greater part of such regions; hence, the supremacy of priests and religious orders and the discouragement of scientific reasoning. Hence, in the arts, the literature, and the religion of India, we see a dominant tendency to the grotesque, the enormous, the fearful; we see gods portrayed with many arms, with three eyes and terrible visages. The legends of their heroes contain monstrous details, as that they lived for many thousands or millions of years. “All this,” says Buckle, “is but a part of that love of the remote, that straining after the infinite, and that indifference to the present, which characterises every branch of Indian intellect. Not only in literature, but also in religion and in art, this tendency is supreme. To subdue the understanding, and indulge the imagination, is the universal principle. In the principles of their theology, in the character of their gods, and even in the form of their temples, we see how the sublime and threatening aspects of the external world have filled the mind of the people with those images of the grand and the terrible, which they strive to reproduce in a visible form, and to which they owe the leading peculiarities of their national culture.”[109]

That these peculiarities of the mental life of such peoples are causally related with those terrible aspects of nature is, I think, sufficiently established by Buckle. But if we admit this, there remain two questions: (1) Have these tendencies become innate racial qualities? (2) If so, how have they been rendered innate? Buckle did not raise these questions and offered no opinion in regard to them. But he seems to have assumed that these tendencies have become innate; and there is much to be said for that view. Yet, if that could be shown conclusively, it still would not prove inheritance of these acquired qualities. It may have resulted in some such way as this: the physical environment stimulates the imagination, and it represses the tendency to control imagination and superstition by reason and calm inquiry after causes; acting thus upon successive generations of men, it determines the peculiarities of the religious system and of the art and literature of the people. Individuals in whom the same tendencies are innately strong will then flourish under such a system; whereas those whose innate tendencies are in the direction of reason and scepticism will find the system uncongenial, unfavourable for the exercise of their best powers; they will fail to make their mark; they may, as in many instances of European inquirers, actually have lost their lives or their liberty through the religious zeal of those who maintain the traditional system. Thus the social environment, working through long ages, may have constantly determined a certain degree of selection of the innate tendencies congenial to it, and a weeding out of the opposed tendencies; until the former have predominated in the race[110].
