INTRODUCTORY NOTE

BY HENRY B. SMITH, D. D.

The History of Philosophy, by Dr. Albert Schwegler, is considered in Germany as the best concise manual upon the subject from the school of Hegel. Its account of the Greek and of the German systems, is of especial value and importance. It presents the whole history of speculation in its consecutive order. Though following the method of Hegel’s more extended lectures upon the progress of philosophy, and though it makes the system of Hegel to be the ripest product of philosophy, yet it also rests upon independent investigations. It will well reward diligent study, and is one of the best works for a text-book in our colleges, upon this neglected branch of scientific investigation. The translation is made by a competent person, and gives, I doubt not, a faithful rendering of the original.

TRANSLATOR’S PREFACE.

Schwegler’s History of Philosophy originally appeared in the “_Neue Encyklopädie für Wissenschaften und Künste_.” Its great value soon awakened a call for its separate issue, in which form it has attained a very wide circulation in Germany. It is found in the hands of almost every student in the philosophical department of a German university, and is highly esteemed for its clearness, conciseness, and comprehensiveness.

The present translation was commenced in Germany three years ago, and has been carefully finished. It was undertaken with the conviction that the work would not lose its interest or its value in an English dress, and with the hope that it might be of wider service in such a form to students of philosophy here. It was thought especially, that a proper translation of this manual would supply a want for a suitable text-book on this branch of study, long felt by both teachers and students in our American colleges.

The effort has been made to translate, and not to paraphrase the author’s meaning. Many of his statements might have been amplified without diffuseness, and made more perceptible to the superficial reader without losing their interest to the more profound student, but he has so happily seized upon the germs of the different systems, that they neither need, nor would be improved by any farther development, and has, moreover, presented them so clearly, that no student need have any difficulty in apprehending them as they are. The translator has therefore endeavored to represent faithfully and clearly the original history. As such, he offers his work to the American public, indulging no hope, and making no efforts for its success beyond that which its own merits shall ensure.
