As a courageous opening of photographic self-observation to the other, the works of the two photographers-JiniAfonso and Natalia Zavialova-allow participation in the search for the self. With the juxtaposition and confrontation of the two oeuvres, the exhibition and catalogue create a nexus that leads to fulgurations in the communication of the photographs-electrical short circuits between the images, the photographers and the viewer. The resulting newness, a temporary third, makes us aware of the subcutaneous connections with ourselves, both as a reflection and as a pictorially emotional experience.

The use of porphyrins for localization and photodynamic therapy of neoplastic disease has been the topic of several international symposia, reviews and books during the preceeding five years. The literature on this topic has continued to grow, as have numbers of presentations at national and international meetings relating to photobiology, chemistry, and lasers. In this volume, it is the intention of the editor to provide both information on current research projects, and detailed methodology used in such investigations. A bibliography on the subjects of porphyrin localization and therapy is included. The manuscripts contained in this volume are based on reports given at a Porphyrin Photosensitization Workshop which was held in Philadel phia, July 6-7, 1984. This Workshop was supported by NIH grant CA 36746, together with funds from the Fogarty International Center. Authors were requested to update their contributions to provide a summary of progress to mid 1985. Manuscripts containing material not presented in Philadelphia are also included, notably a series of articles describ ing current clinical and pre-clinical results from China. Since the Philadelphia Workshop, a meeting was held in Alghero, Sardinia (May, 1985), and additional conferences are now being planned; this attests to the continued interest in photodynamic therapy involving porphyrin photo sensitization.

This is an edition of what are arguably Leibniz’s three most important presentations of his metaphysical system: the Discourse on Metaphysics, from 1686, and The Principles of Nature and of Grace and The Monadology, from 1714. Based on the Latta and Montgomery translations and revised by the editor, these texts set out the essentials of Leibniz’s mature metaphysical views. The edition includes an introductory essay and a set of appendices of seventeenth- and eighteenth-century texts, which help illuminate and contextualize Leibniz’s ideas. Among these are extensive passages from Leibniz’s Theodicy, many of which are cited in The Monadology.
