This volume makes an important contribution toward a nuanced appreciation of the Jesuits' interaction with "modernity," and a greater recognition of their contribution to the mathematization of natural philosophy and experimental science. The six essays provide a cross-section of the complex Jesuit encounter with the mathematical sciences during the 17th century.

The broad canvas covered by the articles in the present volume celebrates the diversity and richness of the writings of Frank Manuel during a scholarly career that spans over five decades. The subjects of the articles - ranging from science to utopia, from theology to political thought - mirror many of the themes Manuel has written about with erudition, flair and uncommon perception. It is only fitting that in paying tribute to such a defiant intellect each author brings to his treatment a distinct perspective and texture, the result of his own original forays into the history of ideas. Yet underlying all the essays is the conviction that the study of the intersection of individuals and ideas still yields a rich harvest. Presented to Frank on the occasion of his eightieth birthday, In the Presence o/the Past honors a teacher, a friend and, above all, a scholar. R. T. Bienvenu and M. Feingold (eds). ln the presence of the past. vii. MARTIN PERETZ Frank Manuel: An Appreciation It was finally because of Frank Edward Manuel that I decided (however belatedly) to forgo a proper academic career. Since I had not left so much as a leafscar on the tree of the scholarly culture this is not a fact which anyone else would have reason to notice. It is also not, I am happy to add, something for which Manuel will be especially remembered.
