Longmans, Green, and Company, 1871 - Logic - 590 pages

"Professor Ueberweg's 'System of Logic' enjoys a popularity among German students which is shared by no other manual. It has already reached three editions, and will soon appear in a fourth. Acquaintance with these facts, personal experience of the value of the book, and the knowledge that there is no really good logical text-book for advanced students in our language, led me to undertake this Translation. While it is not especially intended for beginners, and while the student is recommended to make himself previously familiar with the outlines of Logic as given in such excellent little books as those of Fowler or Jevons, some judicious 'skipping,' in the more difficult parts, will bring this manual down to the level required by those who begin it entirely ignorant of the science"--Foreword.
