The aim of this volume is to investigate the topic of Substance and Attribute. The way leading to this aim is a dialogue between Islamic and Western Philosophy. Our project is motivated by the observation that the historical roots of Islamic and of Western Philosophy are very similar. Thus some of the articles in this volume are dedicated to the history of philosophy, in Islamic thinking as well as in Western traditions. But the dialogue between Islamic and Western Philosophy is not only an historical issue, it also has systematic relevance for actual philosophical questions. The topic Substance and Attribute particularly has an important history in both traditions; and it has systematic relevance for the actual ontological debate. The volume includes contributions (among others) by Hans Burkhardt, Hans Kraml, Muhammad Legenhausen, Michal Loux, Pedro Schmechtig, Muhammad Shomali, Erwin Tegtmeier, and Daniel von Wachter.

The leading idea of the book is to focus on the common roots of Islamic and Western traditions and to increase awareness of the chances of systematic philosophical dispute, with the aim to promote a substantial dialogue on an academic level. Most of the collected papers in this edition are results of contributions to a workshop, organized by the editors of the volume, as an integrated part of a visit to the Imam Khomeini Education and Research Institute (IKERI) of Qom by a delegation of philosophers from the University of Innsbruck in May 2008. The organizational frame of the workshop and also of this edition is the partnership between the IKERI and the University of Innsbruck-the first formal high-level academic partnership between an Iranian Institution and a European University. The contributions in this edition investigate the topic "Soul" in an interdisciplinary and comparative way: Psychologists, Philosophers, and Theologians from both, Islamic and Western traditions, should be brought into dialogue with the focus on the general theme.
