Reflecting and unfolding, in: Ademollo, F., Amerini, F. and De Risi, V. (editors). Thinking and Calculating: Essays in Logic, its History and its Philosophical Applications in Honour of Massimo Mugnai, pp. 1-15, Cham: Springer International Publishing, ISBN:9783030973025,

This book has a twofold nature. It is about something; and it is for someone. On the one hand, it is a collection of twenty-two essays in the history of logic— broadly conceived—written by outstanding specialists in the field. Our aim has been to display the vastness and depth of the developments of logic throughout the centuries, the large array of problems that have fallen within its purview, and the manifold relations that it has entertained with other disciplines. The topics do not cover every aspect of the history of logic, and a few key figures (for example Bolzano or Frege) happen not to be included. In this as in other respects, the volume does not aim to be a textbook providing a comprehensive survey. Rather, it highlights several less-frequented topics and provides a clear picture of some of the most promising developments in recent historiography. Its goal is more to advance cuttingedge research in the field, and display its breadth and diversity, than to encompass the field itself exhaustively. On the other hand, the book is intended as a tribute to Massimo Mugnai, whose contribution to the history of medieval and modern logic, and to the understanding of the writings of Leibniz in particular, have shaped the field in the last four decades. So the volume also aims to illustrate the breadth of Massimo’s work and influence. Some of the authors have been his students in Bari, in Florence, or at the Scuola Normale Superiore in Pisa (where he moved in 2002 and stayed until his retirement in 2017); some have been his colleagues; all have been among hismany interlocutors, collaborators, and friends.
