This book is an exploration into the paradoxical structure of pluralistic thinking as illuminated by both Western and Eastern insights—especially Jainism. By calling into question the most fundamental assumptions of religious pluralists, the author hopes to contribute to a paradigm shift in discourse on religious pluralism and conflicting truth claims.

In this book, David B. Wong defends an ambitious and important new version of moral relativism. He does not espouse the type of relativism that says anything goes, but he does start with a relativist stance against alternative theories such that there need not be only one universal truth. Wong proposes that there can be a plurality of true moralities existing across different traditions and cultures, all with one core human question as to how we can all live together.

When he nished writing, he raised his eyes and looked at me. From that day I have thought about Doktor Pannwitz many times and in many ways. I have asked myself how he really functioned as a man; how he lled his time, outside of the Polymerization and the Indo- Germanic conscience; above all when I was once more a free man, I wanted to meet him again, not from a spirit of revenge, but merely from a personal curiosity about the human soul. Because that look was not one between two men; and if I had known how completely to explain the nature of that look, which came as if across the glass window of an aquarium between two beings who live in different worlds, I would also have explained the essence of the great insanity of the third Germany. PRIMO LEVI [If this is a man, pp. 111–112, in, If this is a man and The truce, trans. S. Woolf, Abacus, London, 1987] If all propositions, even the contingent ones, are resolved into identical propositions, are they not all necessary? My answer is: certainly not. For even if it is certain that what is more perfect is what will exist, the less perfect is nevertheless still possible. In propositions of fact, existence is involved.

The question of relativism is a perennial one, and as fundamental and far reaching as the question of truth itself. Is truth absolute and universal, the same everywhere and for everyone? Or is truth historically, culturally, biologically, or otherwise relative, varying from one epoch or species to another? Although the issues surrounding relativism have attracted especially intense interest of late, they continue to spark heated controversies and to pose problems lacking an obvious resolution. On the side of one prevalent form of relativism, it is argued that we must finally recognize the historical and cultural contingency of our available means of cognition, and therefore abandon as naIve the absolute conception of truth dear to traditional philosophy. According to this line of thinking, even if there were univer sally valid principles, knowledge of them would not be possible for us, and thus an absolute conception of truth must be rejected in light of the demands of critical epistemology. However, when truth is accordingly relativized to some contingent subjective cognitive background, new difficulties arise. One of the most infamous of these is the logical inconsistency of the resulting thesis of relativism itself. Yet an even more serious problem is that the relativization of truth makes truth itself contingent, thereby undermining the motivation for preferring one belief or value to another, or even to its opposite.

This book challenges common debates in philosophy of mind by questioning the framework of placement problems in contemporary metaphysics. The author argues that placement problems arise when exactly one fundamental ontology serves as the base for all entities, and will propose a pluralist alternative that takes the diversity of our conceptual resources and ontologies seriously. This general pluralist account is applied to issues in philosophy of mind to argue that contemporary debates about the mind-body problem are built on this problematic framework of placement problems. The starting point is the plurality of ontologies in scientific practice. Not only can we describe the world in terms of physical, biological, or psychological ontologies, but any serious engagement with scientific ontologies will identify more specific ontologies in each domain. For example, there is not one unified ontology for biology, but rather a diversity of scientific specializations with different ontological needs. Based on this account of scientific practice the author argues that there is no reason to assume that ontological unification must be possible everywhere. Without this ideal, the scope of ontological unification turns out to be an open empirical question and there is no need to present unification failures as philosophically puzzling “placement problems”.

Unity and Plurality presents novel ways of thinking about plurality while casting new light on the interconnections among the logical, philosophical, and linguistic aspects of plurals. The volume brings together new work on the logic and ontology of plurality and on the semantics of plurals in natural language. Plural reference, the view that definite plurals such as 'the students' refer to several entities at once (the individual students), is an approach favoured by logicians and philosophers, who take sentences with plurals ('the students gathered') not to be committed to entities beyond individuals, entities such as classes, sums, or sets. By contrast, linguistic semantics has been dominated by a singularist approach to plurals, taking the semantic value of a definite plural such as 'the students' to be a mereological sum or set. Moreover, semantics has been dominated by a particular ontological view of plurality, that of extensional mereology. This volume aims to build a bridge between the two traditions and to show the fruitfulness of nonstandard mereological approaches. A team of leading experts investigates new perspectives that arise from plural logic and non-standard mereology and explore novel applications to natural language phenomena.
