The modern theory of algebras of binary relations, reformulated by Tarski as an abstract, algebraic, equational theory of relation algebras, has considerable mathematical significance, with applications in various fields: e.g., in computer science---databases, specification theory, AI---and in anthropology, economics, physics, and philosophical logic.
This comprehensive treatment of the theory of relation algebras and the calculus of relations is the first devoted to a systematic development of the subject.
Key Features:
- Presents historical milestones from a modern perspective
- Careful, thorough, detailed guide to understanding relation algebras
- Provides a framework and unified perspective of the subject

Nature in Mind explores a kind of madness at the core of the developed world that has separated the growth of human cultural systems from the destruction of the environment on which these systems depend. It is now becoming increasingly clear that the contemporary Western lifestyle not only has a negative impact on the ecosystems of the earth but also has a detrimental effect on human health and psychological wellbeing. The book compares the work of Gregory Bateson and Henry Corbin and shows how an understanding of the "imaginal world" within the practice of systemic psychotherapy and ecopsychology could provide a language shared by both nature and mind. This book argues the case for bringing nature-based work into mainstream education and therapy practice. It is an invitation to radically reimagine the relationship between humans and nature and provides a practical and epistemological guide to reconnecting human thinking with the ecosystems of the earth.

It has always been understood that the central claim of Christianity-that Jesus born of Mary is the Son of God-is as much a declaration of the mystery of the human as it is the mystery of God; just as the claim that in virtue of this identity he is the Christ who restores, and more, transforms, the created order, intensifies the mystery of the human even further. When the age of revolution was followed by the age of science, and the effort to shape the environment by technology was joined by an injunction to shape societies and economies, and class conflicts became part of world conflicts, the question about the human emerged as a crisis in the meaning of being human. Yet the Catholic mind, preoccupied like every other with the crisis, has conducted its reflection within a tradition of Christian humanism, insisting on the mystery and the tragedy, and still the dignity, of the human. This collection of essays by thirteen Catholic scholars of philosophy, theology, and political thought investigates a range of topics from human sexuality and marriage to moral freedom and responsibility in a pluralistic society, while demonstrating that the Gospel, passed on in an ecclesial tradition, entered into through a sacramental tradition, remains the one radical source of confidence in the quest for human truth.

The Promise of Phenomenology: Posthumous Papers of John Wild includes articles that remained unpublished during Wild's lifetime, a journal, wherein he recorded conversations with major British and Continental philosophers during 1957-8, as well as a masterful exposition and commentary on Emmanuel Levinas's book Totality and Infinity. It also contains a complete bibliography of all of Wild's unpublished writings open for research at the Beinecke Rare Book Library at Yale University. More personal and less reserved than Wild's published scholarship, yet containing Wild's characteristic clarity and rigor, the writings in this book cover such subjects as a phenomenological approach to moral relativism, an exploration of lived time, and reflections on the other and religious transcendence. The Promise of Phenomenology gives a lively picture of a master philosopher at work conveying the vitality and importance of philosophy to everyday life.
