The Brooklyn Eagle:—"A work of marvellous power."
The Independent:—"Keen observation, trenchant criticism, and a conciseness of style combine with unusual force in Mr. Grierson's latest volume on the great war."
The Boston Transcript:—"In 1913 Mr. Grierson wrote a volume of essays called 'The Invincible Alliance' in which he outlined very clearly the dangers which lay before the two great English-speaking nations. Re-reading these essays in the light of the last four years we can see that Mr. Grierson looked even more deeply into the future and that he predicted much which has come to pass since the war began."
The Herald, Washington, D. C.:—"Since the publication of the 'The Invincible Alliance' nothing has appeared in book form to surpass the trenchant vigour and illuminating insight of 'Illusions and Realities of the War.'"
LA VIE ET LES HOMMES
M. Sully Prudhomme, of the French Academy:—"J'ai trouvé ces méditations pleines d'aperçus profonds et sagaces. J'ai été frappé de l'originalité puissante de la pensée de l'auteur."
MODERN MYSTICISM
Maurice Maeterlinck:—"This volume is full of thoughts of the very highest order. You have deliciously and profoundly surprised me. You have said so many things which I should like to have written myself."
A. B. Walkley, dramatic critic of the London Times:—"Modern Mysticism is an original and delectable book."
The London Telegraph:—"Mr. Grierson pierces to the heart of his theme with a keenness that is almost disconcerting. He illumines the most obscure situation by one of his sudden flashes of insight. The poise of his sentences has something of Gallic precision about it and it is not surprising that savants of contemporary French literature have praised his work with generous emphasis. Such an influence, working like leaven in the lump, cannot fail to make its presence appreciated."
