“Cogent, because of brevity and a magnificent prose style, this book wins our quiet praise. It is a fine pamphlet, adding to the value of the series, and should not be missed.”--_Spectator._ “A notable addition to this excellent series. His arguments are a provocation to fruitful thinking.”--_Morning Post._ =The Dance of Çiva=, or Life’s Unity and Rhythm. By COLLUM. “It has substance and thought in it. The author is very much alive and responsive to the movements of to-day.”--_Spectator._ “A very interesting account of the work of Sir Jagadis Bose.”--_Oxford Magazine._ “Has caught the spirit of the Eastern conception of world movements.”--_Calcutta Statesman._ =Lars Porsena=, or the Future of Swearing and Improper Language. By ROBERT GRAVES. _Third impression._ “Goes uncommonly well, and deserves to.”--_Observer._ “Not for squeamish readers.”--_Spectator._ “No more amusingly unexpected contribution has been made to this series. A deliciously ironical affair.”--_Bystander._ “His highly entertaining essay is as full as the current standard of printers and police will allow.”--_New Statesman._ “Humour and style are beyond criticism.”--_Irish Statesman._ =Socrates=, or the Emancipation of Mankind. By H. F. CARLILL. “Devotes a specially lively section to the herd instinct.”--_Times._ “Clearly, and with a balance that is almost Aristotelian, he reveals what modern psychology is going to accomplish.”--_New Statesman._ “One of the most brilliant and important of a remarkable series.”--_Westminster Gazette._ =Delphos=, or the Future of International Language. By E. SYLVIA PANKHURST. “Equal to anything yet produced in this brilliant series. Miss Pankhurst states very clearly what all thinking people must soon come to believe, that an international language would be one of the greatest assets of civilization.”--_Spectator._ “A most readable book, full of enthusiasm, an important contribution to this subject.”--_International Language._ =Gallio=, or the Tyranny of Science. By J. W. N. SULLIVAN, author of “A History of Mathematics.” “So packed with ideas that it is not possible to give any adequate _résumé_ of its contents.”--_Times Literary Supplement._ “His remarkable monograph, his devastating summary of materialism, this pocket _Novum Organum_.”--_Spectator._ “Possesses a real distinction of thought and manner. It must be read.”--_New Statesman._ =Apollonius=, or the Future of Psychical Research. By E. N. BENNETT, author of “Problems of Village Life,” etc.
