The First Philosophers of Greece: An Edition and Translation of the Remaining Fragments of the Pre-Sokratic Philosophers, Together with a Translation of the More Important Accounts of Their Opinions Contained in the Early Epitomes

From the PREFACE.
The Hegelian School, and in particular Zeller, have shown us the place of the earlier thinkers in the history of Greek thought, and the importance of a knowledge of their work for all who wish to understand Plato and Aristotle. Since Zeller's monumental work, several writers (e.g. Benn, Greek Philosophers, vol. i. London 1883; Tannery, Science hellene, Paris 1887; Burnet, Early Greek Philosophy, London 1892) have traced for us the history of this development, but the student who desires to go behind these accounts and examine the evidence for himself still finds the material difficult of access. This material consists of numerous short fragments preserved by later writers, and of accounts of the opinions of these thinkers given mainly by Aristotle and by the Greek doxographists (i.e. students of early thought who made epitomes of the opinions of the masters). The Greek text of the doxographists is now accessible to students in the admirable critical edition of H. Diels (Berlin 1879). The Greek text of the fragments has been published in numerous short monographs, most of which are not readily accessible to the student to-day; it is contained with a vast deal of other matter in Mullach's Fragmenta Graecorum Philosophorum (Paris 1888-1888, vol. i.-iii.), but the text is in many places so carelessly constructed that it does not serve the purposes of the scholar.
In the present work it has been my plan to prepare for the student a Greek text of the fragments of these early philosophers which shall represent as accurately as possible the results of recent scholarship, and to add such critical notes as may be necessary to enable the scholar to see on what basis the text rests. From this text I have prepared a translation of the fragments into English, and along with this a translation of the important passages bearing on these early thinkers in Plato and Aristotle, and in the Greek doxographists as collected by Diels, in order that the student of early Greek thought might have before him in compact form practically all the materials on which the history of this thought is to be based. It has been difficult, especially in the case of Herakleitos and the Pythagoreans, to draw the line between material to be inserted, and that to be omitted; but, in order to keep the volume within moderate limits, my principle has been to insert only the passages from Plato and Aristotle and from the doxographists.
