The shadow of discredit which has hitherto lain upon South America is explained by the continual anarchy to which the majority of its peoples have lent themselves since the immense colonial empire of Spain threw off its fetters in the first quarter of the last century, in order to break up into fifteen separate republics. This anarchy and disorganisation, compared with the orderly spirit of progress which has reigned in the great republic of the North, have given rise to the belief, to-day general, that the so different destiny of these States was due to the special qualities and aptitudes of the Anglo-Saxon race, which the Latin races lacked. This belief results from a superficial and incomplete examination of the facts, and has gained easy acceptance, even in works of a more or less scientific nature, such as _The Psychological Laws of the Evolution of Peoples_, in which the author cites, with regard to the Latin races and the peoples of South America, a number of inaccurate and prejudiced facts, which have been gathered from the writings of a dyspeptic and ill-tempered journalist. Such data have caused M. Gustave Lebon to deduce psychological laws which are hardly favourable to the South American races. If we wish to gain some idea of the true causes of this diversity of destiny between the peoples of North and South America, we must study the origin of each and the particular form which colonisation has assumed in each case; forms imposed by the force of historic facts rather than by the will of man. The Anglo-Saxons arrived in the American coasts and founded, in the first half of the seventeenth century, such cities as Boston, Charleston, Philadelphia, etc., when America had already been discovered and explored by the Spaniards a century and a half before. These colonies were formed of groups of families who had abandoned their mother-country to seek a new one, where they could live and labour free from the persecutions of religious and political intolerance. When these colonies attained a certain fame, the surplus of the overflowing populations of Europe was naturally attracted by these virgin and fertile lands, relatively near at hand though across the ocean. Thus there formed a current of immigration which rapidly peopled America and utilised the great natural resources of its enormous territory. In this way was gradually formed a new people, which was to a certain extent a development of the various nations from which it originated, and which preserved their customs and their political and social habits. These colonists began by buying land of the native tribes; but, increasing in numbers and in strength, they found it more convenient to rob them, thus forcing the Red Indians to retreat towards the north and west; and for reasons of self-respect, or on account of religious principles, no deliberate attempt was made to mingle with the indigenous population.
