This work of Mr. Fiske's may be not unfairly designated the most important contribution yet made by America to philosophical literature.--_The Academy_ (London). DARWINISM, AND OTHER ESSAYS _Crown 8vo, gilt top, $2.00._ If ever there was a spirit thoroughly invigorated by the "joy of right understanding," it is that of the author of these pieces.... No less confident and serene than his acceptance of the utmost logical results of recent scientific discovery is Mr. Fiske's assurance that the foundations of spiritual truths, so called, cannot possibly be shaken thereby.--_The Atlantic Monthly_ (Boston). THE UNSEEN WORLD _And Other Essays. Crown 8vo, gilt top, $2.00._ To each study the writer seems to have brought, besides an excellent quality of discriminating judgment, full and fresh special knowledge, that enables him to supply much information on the subject, whatever it may be, that is not to be found in the volume he is noticing.--_Boston Advertiser._ EXCURSIONS OF AN EVOLUTIONIST _Crown 8vo, gilt top, $2.00._ Among our thoughtful essayists there are none more brilliant than Mr. John Fiske. His pure style suits his clear thought. He does not write unless he has something to say; and when he does write, he shows not only that he has thoroughly acquainted himself with the subject, but that he has to a rare degree the art of so massing his matter as to bring out the true value of the leading points in artistic relief.... The same qualities appear to good advantage in his new volume, which contains his later essays on his favorite subject of evolution.--_The Nation_ (New York). MYTHS AND MYTH-MAKERS _Old Tales and Superstitions interpreted by Comparative Mythology. Crown 8vo, gilt top, $2.00._ Mr. Fiske has given us a book which is at once sensible and attractive, on a subject about which much is written that is crotchety or tedious.--W. R. S. RALSTON, in _The Athenæum_ (London). THE DESTINY OF MAN _Viewed in the Light of His Origin. 16mo, gilt top, $1.00._ One is charmed by the directness and clearness of his style, his simple and pure English, and his evident knowledge of his subject.... Of one thing we may be sure: that none are leading us more surely or rapidly to the full truth than men like the author of this little book, who reverently study the works of God for the lessons which He would teach his children.--_Christian Union_ (New York). THE IDEA OF GOD _As Affected by Modern Knowledge. 16mo, gilt top, $1.00._ The vigor, the earnestness, the honesty, and the freedom from cant and subtlety in his writings are exceedingly refreshing. He is a scholar, a critic, and a thinker of the first order.--_Christian Register_ (Boston). THROUGH NATURE TO GOD _16mo, gilt top, $1.00._ CONTENTS: _The Mystery of Evil_; _The Cosmic Roots of Love and Self-Sacrifice_; _The Everlasting Reality of Religion_.
