The essays collected in this volume were originally contributions to the conference Explanation and Proof in Mathematics: Philosophical and Educational Perspectives, which was held in Essen in November 2006. The essays are substantially extended versions of those papers presented at the conference; each essay has been reviewed by two reviewers and has undergone criticism and revision.

We thank the “Deutsche Forschungsgemeinschaft” (DFG) for the generous funding of the Essen conference in 2006. We also thank the participants and authors for intense and fruitful discussions during the conference and for their generous spirit of cooperation in the preparation of this volume. A multitude of colleagues from history of mathematics, mathematics education and philosophy of mathematics refereed the various papers and thereby helped ensure the quality of this volume. We extend many thanks to them, too. We wish to thank John Holt for his stylistic polishing of much of the manuscript and for his helpful editorial advice and suggestions overall. We are also very grateful to Sarah-Jane Patterson and Stephanie Dick, graduate students in the Institute for History and Philosophy of Science and Technology at the University of Toronto, for their invaluable help in the preparation of the manuscript.
