There is some chance, now that the heat and passion of the war are past, that the vexed questions of nationality and nationalism will be discussed with a little more intelligence and discrimination. Dr. Oakesmith certainly sets a good example. He tells us that he was formerly one of those (they were the vast majority, we think) who had but a vague idea of what they meant by nationality, till he set himself to study the question and classify his mind. The results appear in this very interesting book. He criticises alike the theory that nationality is based on "race," and the opposing theory that there is no such thing as nationality at all. In his own view nationality develops as an evolutionary process, and the full-grown thing may be defined as "organic continuity of common interest." He argues strongly against the internationalist pacifist's contention that nationality is the cause of war, and that peace is to be obtained by the spread of cosmopolitanism. On the contrary, he avows, nationality is "actually the one instrument destined, if wisely directed, to secure lasting and universal peace." This is a statement which most sane persons to-day will accept easily enough. But the crux is the "wise direction." Dr. Oakesmith does not give us much practical guidance on this point. Generalities and fine words are not very helpful, whether they come from the side of passionate enthusiasts for the League of Nations or from those who, like Dr. Oakesmith, are a little doubtful whether the world is quite ripe for it. However, the book is well worth studying, especially on its critical side. WAR-TIME FINANCIAL PROBLEMS. By HARTLEY WITHERS. Murray. 6_s._ net. Mr. Hartley Withers is not only a "financial expert"; he is also a really interesting writer. Even though one may not agree with all his views, one can enjoy this collection of vigorous essays on war finance, company law and banking, currency problems at home and abroad, the conscription of wealth, the theory of Guild socialism. Mr. Withers does not spare his criticism of the Government's financial policy, which has brought us to the verge of bankruptcy. He dismisses the "capital levy" as impracticable; but he advocates a high income tax, with super-tax beginning at a much lower level, and "with skilful differentiation according to the circumstances of the taxpayer."
