Mr. Pearson writes a forecast of what he believes probably will, or at least very possibly may, happen in the development of national life and character during the era upon which we are now entering. He is a man who has had exceptional advantages for his work; he has studied deeply and travelled widely; he has been a diligent reader of books and a keen observer of men. To a careful training in one of the oldest of the world’s universities he has added long experience as an executive officer in one of the world’s youngest commonwealths. He writes with power and charm. His book is interesting in manner, and is still more interesting in matter, for he has thought deeply and faithfully over subjects of immense importance to the future of all the human race. He possesses a mind of marked originality. Moreover, he always faithfully tries to see facts as they actually are. He is, it seems to me, unduly pessimistic; but he is not pessimistic of set purpose, nor does he adopt pessimism as a cult. He tries hard, and often successfully, to make himself see and to make himself state forces that are working for good. We may or may not differ from him, but it behooves us, if we do, to state our positions guardedly; for we are dealing with a man who has displayed much research in getting at his facts and much honesty in arriving at his rather melancholy conclusions. The introduction to Mr. Pearson’s book is as readable as the chapters that follow, and may best be considered in connection with the first of these chapters, which is entitled “The Unchangeable Limits of the Higher Races.” I am almost tempted to call this the most interesting of the six chapters of the book, and yet one can hardly do so when absorbed in reading any one of the other five. Mr. Pearson sees what ought to be evident to every one, but apparently is not, that what he calls the “higher races,” that is, the races that for the last twenty-five hundred years (but, it must be remembered, only during the last twenty-five hundred years) have led the world, can prosper only under conditions of soil and climate analogous to those obtaining in their old European homes. Speaking roughly, this means that they can prosper only in the temperate zones, north and south.
