“Few of the 50 volumes, provocative and brilliant as most of them have been, capture our imagination as does this one.”—_Daily Telegraph._ “The historical part is as brilliant a piece of packed writing as could be desired.”—_Daily Herald._ “Serves a national end. The book is in essence a pamphlet, though it has the form and charm of a book.”—_Spectator._ =Janus=, or the Conquest of War. By WILLIAM MCDOUGALL, M.B., F.R.S. “Among all the booklets of this brilliant series, none, I think is so weighty and impressive as this. It contains thrice as much matter as the other volumes and is profoundly serious.”—Dean Inge, in _Evening Standard_. “A deeply interesting and fair-minded study of the causes of war and the possibilities of their prevention. Every word is sound.”—_Spectator._ =Vulcan=, or the Future of Labour. By CECIL CHISHOLM. “Of absorbing interest.”—_Daily Herald._ “No one, perhaps, has ever condensed so many hard facts into the appearance of agreeable fiction, nor held the balance so nicely between technicalities and flights of fancy, as the author of this excellent book in a brilliant series. _Vulcan_ is a little book, but between its covers knowledge and vision are pressed down and brimming over.”—_Spectator._ =Hymen=, or the Future of Marriage. By NORMAN HAIRE. This candid and unprejudiced survey inquires why the majority of marriages to-day seem to be so unsatisfactory, and finds the answer in the sexual ethic of our civilization which is ill adapted to our social and economic needs. The problems of sex-morality, sex-education, prostitution, in-breeding, birth-control, trial-marriage, and polygamy are all touched upon. =The Next Chapter=: the War against the Moon. By ANDRÉ MAUROIS, author of ‘Ariel’, etc. This imaginary chapter of world-history (1951-64) from the pen of one of the most brilliant living French authors mixes satire and fancy in just proportions. It tells how the press of the world is controlled by five men, how world interest is focussed on an attack on the moon, how thus the threat of world-war is averted. But when the moon retaliates.... =Galatea=, or the Future of Darwinism. By W. RUSSELL BRAIN. This non-technical but closely-reasoned book is a challenge to the orthodox teaching on evolution known as Neo-Darwinism. The author claims that, although Neo-Darwinian theories can possibly account for the evolution of forms, they are quite inadequate to explain the evolution of functions. =Scheherazade=, or the Future of the English Novel. By JOHN CARRUTHERS. A survey of contemporary fiction in England and America lends to the conclusion that the literary and scientific influences of the last fifty years have combined to make the novel of to-day predominantly analytic. It has thus gained in psychological subtlety, but lost its form. How this may be regained is put forward in the conclusion.
