The issues of the nature and existence of God, time and infinity, respectively, and how they relate to each other, are some of the most complicated problems of metaphysics.This volume presents contributions of thirteen internationally renowned scholars who deal with various aspects of these complex issues. The contributions were presented and discussed during the international conference: God, Time, Infinity held in Warsaw, September 22-24, 2015.

The book God, Truth, and other Enigmas is a collection of eighteen essays that fall under four headings: (God's) Existence/Non-Existence, Omniscience, Truth, and Metaphysical Enigmas. The essays vary widely in topic and tone. They provide the reader with an overview of contemporary philosophical approaches to the subjects that are indicated in the title of the book.

The old philosophical discipline of metaphysics - after having been pronounced dead by many - has enjoyed a significant revival within the last thirty years, due to the application of the methods of analytic philosophy. One of the major contributors to this revival is the outstanding American metaphysician Peter van Inwagen. This volume brings together twenty-two scholars, who, in commemoration of Prof. van Inwagen's 75th birthday, ponder the future prospects of metaphysics in all the richness to which it has now returned. It is only natural that logical and epistemological reflections on the significance of metaphysics - sometimes called "meta-metaphysics" - play a considerable role in most of these papers. The volume is further enriched by an interview with Peter van Inwagen himself.

The content of the volume is divided as follows: after presenting two rival approaches to substantiality and causality: a traditional (ontological) view vs. a transcendental one (Rosiak) there follow two sections: the first presents studies of substance as showing some causal aspects (Buchheim, Keinanen, Kovac, Piwowarczyk), whereas the other contains investigations of causality showing in a way its reference to the category of substance (Kobiela, Meixner, Mitscherling, Wronski). The last, short section contains two studies of extension (Leszczynski and Skowron) which can be regarded as a conceptual background of both substantiality and causality. The book gives a very colourful picture of the discussions connected with substantiality and causality which may be of potential interest for the readers.

The book Ontological Proofs Today, apart from the introduction, consists of six parts. Part II comprises papers each of which pertains either to historical ontological arguments, or to some other, rather new, ontological arguments, but what makes them stand out from the other papers in this volume, is the fact that they all treat of the omniscience or the omnipotence of God. Part III includes papers which introduce new ontological arguments for the existence of God, without referring to omniscience and omnipotence as the transparent attributes of God. The issue of the type of necessity with which ontological proofs work or may work is raised in the articles of Part IV. In Part V the semantics for some ontological proofs are defined. Part VI consists of papers which, although quite different from each other in terms of content, all explore some ontological issues, and formal ontology may be considered the link between them. Part VII comprises two articles, by R. E. Maydole and G. Oppy, mutually controversial and different in their assessment of some ontological proofs.

This volume aims to apply ontological theories and arguments to theistic beliefs and theistic world views. After an introduction that traces out the complexity of the field by categorizing the multifaceted definitions of ontology and (theistic) believing, thirteen articles discuss specific aspects of the two terms as well as their interaction. With contributions by Chris Daly, Gabriele De Anna, Michal Glowala, Christian Kanzian, Daniel Linford, Jason Megill, Uwe Meixner, Elisa Paganini, Eleonore Stump, Miroslaw Szatkowski, William F. Vallicella and Peter van Inwagen.

This volume collects fifteen original essays on E. J. Lowe's work on metaphysics and ontology. The essays connect Lowe's insights with contemporary issues in metaphysics. E. J. Lowe (1950-2014) was one of the most influential analytical philosophers of the twentieth and early twenty-first century. Drawing inspiration from Aristotle's thought, E. J. Lowe treated metaphysics as an autonomous discipline concerned with the fundamental structure of reality. The chapters in this volume reflect on his path-breaking work. They deal with a wide range of metaphysical issues including four-category ontology, the causal and non-causal aspects of agency, categorial fundamentality and non-fundamentality, the existence of relations, property dualism, powers and abilities, personal identity, predication, and topological ontology. Taken together, the chapters reflect the liveliness of contemporary debates in metaphysics and the enduring impact of Lowe's thought on them. E. J. Lowe and Ontology will be of interest to researchers and advanced students working in metaphysics and philosophy of mind.
