knowledge to be the indispensable condition for a right comprehension of his meaning. So far as I am aware, neither the "Fourfold Root" nor the "Will in Nature" have as yet found a translator; therefore, considering the dawning interest which has begun to make itself felt for Schopenhauer's philosophy in England and in America, and the fact that no more competent scholar has come forward to do the work, it may not seem presumptuous to suppose that this version may be acceptable to those who wish to acquire a more than superficial knowledge of this remarkable thinker, yet whose acquaintance with German does not permit them to read his works in the original. Now although some portions of both the Essays published in the present volume have of course become antiquated, owing to the subsequent development of the empirical sciences, while others--such as, for instance, Schopenhauer's denunciation of plagiarism in the cases of Brandis and Rosas in the beginning of Physiology and Pathology[2]--can have no interest for the reader of the present day, I have nevertheless given them just as he left them and refrained from all suppression or alteration. And if, on the whole, the "Will in Nature" may be less indispensable for a right understanding of our philosopher's views than the "Fourfold Root," being merely a record of the confirmations which had been contributed during his lifetime by the various branches would thus be more readily understood. As however he uses the word '_idea_' everywhere else exclusively in its original (Platonic) sense, I have preferred to avoid needless confusion by adhering to his own declaration and definition. Besides, many English writers of note have protested against any other sense being given to it, and modern German philosophers have more and more returned to the original meaning of the term.
