ore popular, than in our opinion its intrinsic
importance would entitle it to demand. To satisfy every one in the choice
of subjects and in the extent of the discussion is impossible; but our hope
is that those who would have preferred a guide of this sort to be entirely
different will not prove too numerous. In the classification of movements
and schools, and in the arrangement of the contents of the various systems,
it has not been our aim to deviate at all hazards from previous accounts;
and as little to leave unutilized the benefits accruing to later comers
from the distinguished achievements of earlier workers in the field. In
particular we acknowledge with gratitude the assistance derived from the
renewed study of the works on the subject by Kuno Fischer, J.E. Erdmann,
Zeller, Windelband, Ueberweg-Heinze, Harms, Lange, Vorlander, and Puenjer.

The motive which induced us to take up the present work was the perception
that there was lacking a text-book in the history of modern philosophy,
which, more comprehensive, thorough, and precise than the sketches of
Schwegler and his successors, should stand between the fine but detailed
exposition of Windelband, and the substantial but--because of the division
of the text into paragraphs and notes and the interpolation of pages of
bibliographical references--rather dry outline of Ueberweg. While the
former refrains from all references to the literature of the subject and
the latter includes far too many, at least for purposes of instruction, and
J.B. Meyer's _Leitfaden_ (1882) is in general confined to biographical and
bibliographical notices; we have mentioned, in the text or the notes and
with the greatest possible regard for the progress of the exposition, both
the chief works of the philosophers themselves and some of the
treatises concerning them. The principles which have guided us in these
selections--to include only the more valuable works and those best adapted
for students' reading, and further to refer as far as possible to the most
recent works--will hardly be in danger of criticism. But we shall not
dispute the probability that many a book worthy of mention may have been
overlooked.

The explanation of a number of philosophical terms, which has been added as
an appendix at the suggestion of the publishers, deals almost entirely
with foreign expressions and gives the preference to the designations of
fundamental movements. It is arranged, as far as possible, so
