""If the History of Philosophy admitted of no other mode of treatment than either the simply learned, which regards all systems as equally true, as being alike mere opinions; or the sceptical, which sees equal error in all; or lastly, the eclectic, which discovers fragments of the truth in all, we should have to agree that those are right who, in the interests of philosophy, warn all, or at least beginners, against studying its history. But whether a better method exists, and which is the right one, can only be decided by a consideration of the conception of a history of philosophy. The attention of the reader is directed to what the Author says in his prefaces in explanation of two characteristics of his work --the relatively full treatment of the Middle Ages, and the principle on which the bibliography has been given."--Book."@en
