Possibility And Actuality

Actuality, Possibility and Worlds is an exploration of the Aristotelian account that sees possibilities as grounded in causal powers. On his way to that account, Pruss surveys a number of historical approaches and argues that logicist approaches to possibility are implausible. The notion of possible worlds appears to be useful for many purposes, such as the analysis of counterfactuals or elucidating the nature of propositions and properties. This usefulness of possible worlds makes for a second general question: Are there any possible worlds and, if so, what are they? Are they concrete universes as David Lewis thinks, Platonic abstracta as per Robert M. Adams and Alvin Plantinga, or maybe linguistic or mathematical constructs such as Heller thinks? Or is perhaps Leibniz right in thinking that possibilia are not on par with actualities and that abstracta can only exist in a mind, so that possible worlds are ideas in the mind of God?

Nicolai Hartmann's Possibility and Actuality is the second volume of a four-part investigation of ontology. It deals with such questions as: How do we know that something is really possible? Is the possible only the actual? Is the actual only the possible? What is the difference between ideal and real possibility? This groundbreaking work of modal analysis describes the logical relations between possibility, actuality, and necessity, and it provides insight into the relations between modes of knowledge and modes of being. Hartmann reviews the history of philosophical concepts of possibility and necessity, from ancient Megarian philosophy to Aristotle, to Medieval Scholasticism, to Leibniz, Kant, and Hegel. He explains the importance of modal analysis as a basic investigative tool, and he proposes an approach to understanding the nature of human existence that unifies the fields of ontology, modal logic, metaphysics, and epistemology. This brilliant and fascinating work is relevant to many topics of debate in contemporary philosophy, including the ontology of possible worlds, the metaphysics of modality, the logic of counterfactual conditionals, and modal epistemology. It illuminates the nature of real, ideal, logical, and epistemic possibility.

The Actual and the Possible presents new essays by leading specialists on modality and the metaphysics of modality in the history of modern philosophy from the seventeenth to the twentieth centuries. It revisits key moments in the history of modern modal doctrines, and illuminates lesser-known moments of that history. The ultimate purpose of this historical approach is to contextualise and even to offer some alternatives to dominant positions within the contemporary philosophy of modality. Hence the volume contains not only new scholarship on the early-modern doctrines of Baruch Spinoza, G. W. F. Leibniz, Christian Wolff and Immanuel Kant, but also work relating to less familiar nineteenth-century thinkers such as Alexius Meinong and Jan Lukasiewicz, together with essays on celebrated nineteenth- and twentieth-century thinkers such as G. W. F. Hegel, Martin Heidegger and Bertrand Russell, whose modal doctrines have not previously garnered the attention they deserve. The volume thus covers a variety of traditions, and its historical range extends to the end of the twentieth century, addressing the legacy of W. V. Quine's critique of modality within recent analytic philosophy.

In this book, Mikhail Epstein offers a systematic theory of modalities (possible, actual, necessary) and their impact on the philosophy and culture of modernity and postmodernity, focusing on the creative potentials of possibilistic thinking for the humanities.

Possibility is a philosophical treatise on the metaphysical concepts of possibility and necessity. Jubien rejects the idea of possible worlds, and starts instead the notion of a physical object and the positing of properties and relations. He has new things to say about such topics as essentialism, natural kinds, and proper names.

Timothy Williamson gives an original and provocative treatment of deep metaphysical questions about existence, contingency, and change, using the latest resources of quantified modal logic. Contrary to the widespread assumption that logic and metaphysics are disjoint, he argues that modal logic provides a structural core for metaphysics.

What is it for you to be conscious? There is no consensus in philosophy or science: it has remained a mystery. Ted Honderich develops a brand new theory of consciousness, according to which perceptual consciousness is external to the perceiver. It exists in a subjective physical world dependent on both you and the objective physical world.

A Theory of the Absolute develops a worldview that is opposed to the dominant paradigm of physicalism and atheism. It provides powerful arguments for the existence of the soul and the existence of the Absolute. It shows that faith is not in contradiction to reason.
