The foundations of this edition were laid at the University of Bochum. The readiness with which Professor Poggeler and his staff put the full resources of the Hegel Archive at my disposal, and went out of their way in helping me to survey the field and get t9 grips with the editing of the manuscript material, has put me very greatly in their debt. I could never have cleared the ground so effectively anywhere else, and I should like to express my very deep grati­ tude for all the help and encouragement they have given me. It has been completed in the Netherlands, - in a University which is justly proud of both the liberal and humanistic traditions of its country and its close links with the enterprise and accomplishments of a great com­ mercial city, and in a faculty engaged primarily in establishing itself as a centre of inter-disciplinary research. I have found these surroundings thoroughly congenial, and can only hope that the finished work will prove worthy of its setting.
