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.
