In difficult cir- cumstances, we may set our minds free by focusing on a specific agenda. After having uncovered the infrastructure of John Duns Scotus’ theology (Johannes Duns Scotus, 1994), I returned to the sphere of philosophy to concentrate on the massive issue of Duns Scotus’ own philosophy. I underestimated somewhat the enormity of the task to clean up the research regarding John Duns Scotus’ life, works, and philosophical thought. However, my obsession was made lighter and livelier by Marriëtte, Toon, and Elisabeth, my home front and a haven of relief and joy, always fond of keen exchanges of thought to soothe the practical pressures of writing a large book. I have continually been supported by the wonderful presence of the Research Group John Duns Scotus which gathers regularly in Dordrecht. John Duns’ philosophy is a philosophy of individual dignity and goodness, love and friendship. I am grateful for and proud of this unique band of inspirational scholars (Henri Veldhuis, Eef Dekker, Nico den Bok, Klaas Bom, Andreas Beck, Martijn Bac), still going strong in their contributions to Scotist scholarship. Likewise, Ienjoy the link between past and present in the Utrecht days of study- ing and promoting theology (Nico den Bok, Guus Labooy, Arjan Plaisier). We are rediscovering the past in order to infuse present debates with the riches of the classic heritage of Western thought of the past millennium. I am grateful for and proud of such excellent young scholars who started out as students but became my pupils and then my friends who helped prevent me from making mistakes. Investigating Duns Scotus’ thought is a massive undertaking, just as is writing in English. Without the cordial support of Jerry Etzkorn I would certainly not have succeeded in producing an acceptable book. By correcting my The Philosophy of John Duns Scotus Jerry saved my book, and hopefully my work. Just as Professor Girard Etzkorn took care of my English, Dr Guus Labooy took care of my computer version. Mille grazie. I am also grateful for the financial viii The Philosophy of John Duns Scotus support I received from the Theologisch Wetenschappelijk Instituut (the Protestant Church in the Netherlands). Without De Rijk’s contributions to philosophical scholarship, Icould not have mastered the tools indispensable for reading and ana- lyzing systematic texts of medieval theologians and philosophers. The membership of Medium Aevum is a precious gift to me. I received fine support from Dr Bert Bos in semantic matters and the criticisms Professor H. A. G. Braakhuis bestowed on my work with meticulous care provided me with singular help, particularly in bridging the dis- tance between evidence and conclusions. I feel truly grateful for this assistance. I am impressed by the sense of responsibility of the staff and the board of Edinburgh University Press and of the referees. Jackie Jones, former philosophy editor, deserves my deeply felt gratitude for her wise encouragement and keen involvement. Working together with her successor Carol Macdonald was always a source of joy. Heartfelt thanks go also to the copyeditor Peter Williams for his hard, efficient, and excellent work. The admirable style and competence of all members of staff I have worked with has surprised me – and surprised me I have to confess in a most pleasant way. Almost twenty-five years ago in 1981, I showed how the main con- cepts of Duns Scotus’ theory of science constitute a coherent web of ideas based on his central logical and ontological innovations, and utilizing the basic notion of synchronic contingency as a matrix in his theory. The great challenge was to investigate whether this same innovation could be the key to understanding the whole of his phi- losophy. The journey of this research became a breathtaking adven- ture, an adventure in retrospect which succeeded due to the quality of Scotus’ thought. The main text of The Philosophy of John Duns Scotuswas finished in the summer of 2003. I hope to finish The Theology of John Duns Scotus in the course of 2005–6. It is an existential comfort to contribute to coherent philosophy, transcending the subjectivities of individual thinkers. It is a true gift to discover an oeuvre from the past, embodying, in principle, a coher- ent world of philosophical and theological thought. It is a wonderful experience to discover in addition that this world of theological and philosophical thinking also provided the foundations for the per- spectives and dilemmas of mainstream Western thought for centuries. John Duns Scotus suddenly died in Cologne, in Germany’s Rhineland, in 1308, still a young professor of only forty-two years of Preface and acknowledgements ix age. It was a sad blow to the development of Western thought. Nevertheless, we shall have something to celebrate in 2008. Dordrecht, The Netherlands Advent 2005 [email protected] www.dunsscotus.com
