Sufficient Reason

The Principle of Sufficient Reason (PSR) says that all contingent facts must have explanation. In this 2006 volume, which was the first on the topic in the English language in nearly half a century, Alexander Pruss examines the substantive philosophical issues raised by the Principle Reason. Discussing various forms of the PSR and selected historical episodes, from Parmenides, Leibnez, and Hume, Pruss defends the claim that every true contingent proposition must have an explanation against major objections, including Hume's imaginability argument and Peter van Inwagen's argument that the PSR entails modal fatalism. Pruss also provides a number of positive arguments for the PSR, based on considerations as different as the metaphysics of existence, counterfactuals and modality, negative explanations, and the everyday applicability of the PSR. Moreover, Pruss shows how the PSR would advance the discussion in a number of disparate fields, including meta-ethics and the philosophy of mathematics.

In the standard analysis of economic institutions--which include social conventions, the working rules of an economy, and entitlement regimes (property relations)--economists invoke the same theories they use when analyzing individual behavior. In this profoundly innovative book, Daniel Bromley challenges these theories, arguing instead for "volitional pragmatism" as a plausible way of thinking about the evolution of economic institutions. Economies are always in the process of becoming. Here is a theory of how they become. Bromley argues that standard economic accounts see institutions as mere constraints on otherwise autonomous individual action. Some approaches to institutional economics--particularly the "new" institutional economics--suggest that economic institutions emerge spontaneously from the voluntary interaction of economic agents as they go about pursuing their best advantage. He suggests that this approach misses the central fact that economic institutions are the explicit and intended result of authoritative agents--legislators, judges, administrative officers, heads of states, village leaders--who volitionally decide upon working rules and entitlement regimes whose very purpose is to induce behaviors (and hence plausible outcomes) that constitute the sufficient reasons for the institutional arrangements they create. Bromley's approach avoids the prescriptive consequentialism of contemporary economics and asks, instead, that we see these emergent and evolving institutions as the reasons for the individual and aggregate behavior their very adoption anticipates. These hoped-for outcomes comprise sufficient reasons for new laws, judicial decrees, and administrative rulings, which then become instrumental to the realization of desired individual behaviors and thus aggregate outcomes.

This book explores and compares the reflections on space and quantity found in the works of five philosophers: Spinoza, Leibniz, Bergson, Whitehead, and Deleuze. What unites these philosophers is a series of metaphysical concerns rooted in 17th-century rationalism and embraced in 20th-century philosophies of process and difference. At the heart of these concerns is the need for a comprehensive metaphysical account of the diversity and individuality of things. This demand leads to a shared critique of Cartesian and Newtonian conceptions of space. The most problematic aspect of those notions of space is homogeneity. In essence, uniform space fails to explain the differences between locations, thus violating the Principle of Sufficient Reason. Cartesian and Newtonian theories of space thereby fail to meet the metaphysical requirement for explaining diversity and individuality. The traditional concept of quantity faces similar issues. Motivated by these problems, these five philosophers developed an alternative conception of space and quantity. By examining these theories, the book sheds new light on an unexplored relation between rationalism and 20th-century Continental philosophy. A Geometry of Sufficient Reason will appeal to scholars and graduate students working in Continental philosophy, history of philosophy, metaphysics, and the history and philosophy of science.

This book is a philosophical commentary on Schopenhauer's "Fourfold Root of the Principle of Sufficient Reason," dealing with each of Schopenhauer's principal topics in turn. It also provides the reader with a general survey of Schopenhauer's later philosophical views and puts them into an historical context

A new 2023 translation of Schopenhauer's 1813 Über die vierfache Wurzel des Satzes vom zureichenden Grunde, his dissertation which earned him his Ph.D. This is volume I in the Complete works of Arthur Schopenhauer by Newcomb Livraria Press. As Marx’s dissertation on an Epicurean version of Hegelianism defined his entire philosophic-economic project, so Schopenhauer’s dissertation on the Principle of Sufficient Reason defines his entire career. This work was his dissertation for his PhD from the University of Jena (also Hegel's Alma motta). Leibniz's Enlightenment Principle of Sufficient Reason, developed from Aristotelianism’s hybridization with medieval Catholicism immediately following the Great Schism, is the basis of Schopenhauer’s criticisms of Kant and the foundation of his later works. This is a distinct variation which builds out Leibnitz's Monadology in four directions- Becoming, Knowing, Being and Willing.

"On the Fourfold Root of the Principle of Sufficient Reason & On the Will in Nature: Two Essays" by Arthur Schopenhauer, translated by Karl Mme. Hillebrand, is a philosophical work that delves into profound questions about the nature of existence and human understanding. Schopenhauer's essays explore the concept of sufficient reason and the role of the will in the natural world. The book offers readers a deep and thought-provoking exploration of philosophical ideas and their implications. "On the Fourfold Root of the Principle of Sufficient Reason & On the Will in Nature" is a challenging yet rewarding read for those interested in philosophical discourse.

"Schopenhauer's analyses of causation and related concepts . . . rival and probably surpass in their depth and brilliance the more celebrated discussions of David Hume. Where Hume grossly oversimplified these problems and left them riddled with paradoxes, Schopenhauer disentangled them and shed light on what had seemed hopelessly dark." --Richard Taylor, University of Rochester

This volume of translations unites three shorter works by Arthur Schopenhauer that expand on themes from his book The World as Will and Representation. In On the Fourfold Root he takes the principle of sufficient reason, which states that nothing is without a reason why it is, and shows how it covers different forms of explanation or ground that previous philosophers have tended to confuse. Schopenhauer regarded this study, which he first wrote as his doctoral dissertation, as an essential preliminary to The World as Will. On Will in Nature examines contemporary scientific findings in search of corroboration of his thesis that processes in nature are all a species of striving towards ends; and On Vision and Colours defends an anti-Newtonian account of colour perception influenced by Goethe's famous colour theory. This is the first English edition to provide extensive editorial notes on the different published versions of these works.
