important contribution yet made by America to philosophical
literature.--_The Academy_ (London).


DARWINISM, AND OTHER ESSAYS.

If ever there was a spirit thoroughly invigorated by the "joy of right
understanding" it is that of the author of these pieces. Even the reader
catches something of his intellectual buoyancy, and is thus carried
almost lightly through discussions which would be hard and dry in the
hands of a less animated writer.... 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. 12mo, $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. To the
knowledge, analytical power, and faculty of clear statement, that appear
in all these papers, Mr. Fiske adds a just independence of thought that
conciliates respectful consideration of his views, even when they are
most at variance with the commonly accepted ones.--_Boston Advertiser_.
