In Opera as Art: Philosophical Sketches, Paul Thom argues for opera as an art, standing alongside other artforms that employ visual and sonic media to embody the great themes of human life. Thom contends that in great operatic art, the narrative and expressive content collaborate with the work's aesthetic qualities towards achieving this aim. This argument can be extended to modern operatic productions. At their best, these stagings are works of art in themselves, whether they give faithful renditions of the operas they stage and whether their aims go beyond interpretation to commentary and critique. This book is a philosophical introduction to the key practices that comprise the world of opera: the making of the work; its interpretation by directors, critics, and spectators; and the making of an operatic production. Opera has always existed in a context of philosophical ideas, and this book is written for opera-lovers who would like to learn something about that philosophical context.

Paul Thom's book presents Kilwardby's science of logic as a body of demonstrative knowledge about inferences and their validity, about the semantics of non-modal and modal propositions, and about the logic of genus and species. This science is thoroughly intensional. It grounds the logic of inference on that in virtue of which the inference holds. It bases the truth conditions of propositions on relations between conceptual entities. It explains the logic of genus and species through the notion of essence. Thom interprets this science as a formal logic of intensions with its own proof theory and semantics. This comprehensive reconstruction of Kilwardby's logic shows the medieval master to be one of the most interesting logicians of the thirteenth century.

This book recounts the remarkable history of efforts by significant medieval thinkers to accommodate the ontology of the Trinity within the framework of Aristotelian logic and ontology. These efforts were remarkable because they pushed creatively beyond the boundaries of existing thought while trying to strike a balance between the Church's traditional teachings and theoretical rigor in a context of institutional politics. In some cases, good theology, good philosophy, and good politics turned out to be three different things. The principal thinkers discussed are Augustine, Boethius, Abelard, Gilbert of Poitiers, Bonaventure, Aquinas, Scotus, and Ockham. The aspects of Trinitarian doctrine dealt with are primarily internal ontological questions about the Trinity. The approach draws on history of theology and philosophy, as well as on the modern formal disciplines of set-theoretic semantics and formal ontology. Augustine inaugurated the project of constructing models of the Trinity in language drawn from Platonic and Aristotelian philosophy, especially the conceptual framework of Aristotle's Categories. He used the Aristotelian notions of substance and relation to set up a model whose aim was not so much to demystify the Trinity as to demonstrate the logical consistency of maintaining that there is one and only one God at the same time as maintaining that there are three distinct persons, each of whom is God. Standing against this tradition are various heretical accounts of the Trinity. The book also analyzes these traditions, using the same techniques. All these accounts of the Trinity are evaluated relative to the three constraints under which they were formed, bearing in mind that the constraints on philosophical theorizing are not limited to internal consistency but also take note of explanatory power. Besides analyzing and evaluating individual accounts of the Trinity, the book provides a novel framework within which different theories can be compared.

Critics and artists (including performing artists) claim the title of 'interpreter' for themselves. Scientists do not so readily describe themselves in this way. But is the formulation of explanatory hypotheses in science so different from the interpretive work of artists? Making Sense recognizes that whenever interpretation occurs there may be a plurality of competing successful interpretations. It offers a philosophical theory that views the interpretive enterprise as an attempt to make sense of things by representing them in ways that can be accommodated within various significance-systems.
