Leibniz's monads have long been a source of fascination and puzzlement. If monads are merely immaterial, how can they alone constitute reality? In Monads, Composition and Force, Richard T. W. Arthur takes seriously Leibniz's claim of introducing monads to solve the problem of the composition of matter and motion. Going against a trend of idealistic interpretations of Leibniz's thought, Arthur argues that although monads are presupposed as the principles making actual each of the infinite parts of matter, bodies are not composed of them. He offers a fresh interpretation of Leibniz's theory of substance in which monads are enduring primitive forces, corporeal substances are embodied monads, and bodies are aggregates of monads, not mere appearances. In this reading the monads are constitutive unities, constituting an organic unity of function through time, and bodies are phenomenal in two senses; as ever-changing things they are Platonic phenomena and as pluralities, in being perceived together, they are also Democritean phenomena. Arthur argues for this reading by describing how Leibniz's thought is grounded in seventeenth century atomism and the metaphysics of the plurality of forms, showing how his attempt to make this foundation compatible with mechanism undergirds his insightful contributions to biological science and the dynamical foundations he provides for modern physics.

In this book, Arthur gives fresh interpretations of Gottfried Leibniz's theories of time, space, and the relativity of motion, based on a thorough examination of Leibniz's manuscripts as well as his published papers. These are analysed in historical context, but also with an eye to their contemporary relevance. Leibniz's views on relativity have been extremely influential, first on Mach, and then on Einstein, while his novel approach to geometry in his analysis situs inspired many later developments in geometry. Arthur expounds the latter in some detail, explaining its relationship to Leibniz's metaphysics of space and the grounding of motion, and defending Leibniz's views on the relativity of motion against charges of inconsistency. The brilliance of his work on time, though, has not been so well appreciated, and Arthur attempts to remedy this through a detailed discussion of Leibniz's relational theory of time, showing how it underpins his theory of possible worlds, his complex account of contingency, and his highly original treatment of the continuity of time, providing formal treatments in an appendix. In other appendices, Arthur provides translations of previously untranslated writings by Leibniz on analysis situs and on Copernicanism, as well as an essay on Leibniz's philosophy of relations. In his introductory chapter he explains how the framework for the book is provided by the interpretation of Leibniz's metaphysics he defended in his earlier Monads, Composition, and Force (OUP 2018, winner of the 2019 annual JHP Book Prize for best book in the history of philosophy published in 2018).

In The Fold, Laura U. Marks offers a practical philosophy and aesthetic theory for living in an infinitely connected cosmos. Drawing on the theories of Leibniz, Glissant, Deleuze, and theoretical physicist David Bohm—who each conceive of the universe as being folded in on itself in myriad ways—Marks contends that the folds of the cosmos are entirely constituted of living beings. From humans to sandwiches to software to stars, every entity is alive and occupies its own private enclosure inside the cosmos. Through analyses of fiction, documentary, and experimental movies, interactive media, and everyday situations, Marks outlines embodied methods for detecting and augmenting the connections between each living entity and the cosmos. She shows that by affectively mediating with the ever-shifting folded relations within the cosmos, it is possible to build “soul-assemblages” that challenge information capitalism, colonialism, and other power structures and develop new connections with the infinite. With this guide for living within the enfolded and unfolding cosmos, Marks teaches readers to richly apprehend the world and to trace the processes of becoming that are immanent within the fold.

The Monadology (French: La Monadologie, 1714) is one of Gottfried Leibniz's best known works representing his later philosophy. It is a short text which sketches in some 90 paragraphs a metaphysics of simple substances, or monads. In it, he offers a new solution to mind and matter interaction by means of a pre-established harmony expressed as the 'Best of all possible worlds' form of optimism.

A new understanding of Kant’s theory of a priori knowledge and his natural philosophy emerges from Jeffrey Edwards’s mature and penetrating study. In the Third Analogy of Experience, Kant argues for the existence of a dynamical plenum in space. This argument against empty space demonstrates that the dynamical plenum furnishes an a priori necessary condition for our experience and knowledge of an objective world. Such an a priori existence proof, however, transgresses the limits Kant otherwise places on transcendental arguments in the Critique of Pure Reason because it establishes a material transcendental condition of possible experience. This finding motivates Edwards to examine the broader context of Kant’s views about matter, substance, causal influence, and physical aether in connection with the developmental history of his theory of transcendental idealism. Against the backdrop of early modern metaphysics and contemporaneous physical theory, Edwards explicates the origins of the Third Analogy in Kant’s early work on the metaphysics of nature. The argument against empty space presented in the Third Analogy reveals a central aspect of Kant’s transcendental theory of experience that Edwards explains lucidly. By clarifying the epistemological standpoint at issue in the Third Analogy, he shows that the fundamental revisions to which Kant subjects his theory of knowledge in the Opus postumum not only originate in his precritical metaphysics of nature but are developments of an argument central to the Critique of Pure Reason itself. Edwards’s work is important to scholars working in the history of philosophy and the history and philosophy of science, as well as to Kant specialists.

This interdisciplinary book ties the historical work of Descartes to his successors through current research and critical overviews on the neuroscience of consciousness, the brain, and cognition. This text is the first historical survey to focus on the cohesions and discontinuities between historical and contemporary thinkers working in philosophy, physiology, psychology, and neuroscience. The book introduces and analyzes early discussions of consciousness, such as: metaphysical alternatives to scientific explanations of consciousness and its connection to brain activity; claims about the possibilities and limits of neuroscientific accounts of consciousness and cognition; and the proposition of a “non-reductive naturalism” concerning phenomenal consciousness and rationality. The author assesses the contributions of early philosophers and scientists on brain, consciousness and cognition, among them: Descartes, Malebranche, Spinoza, Leibniz, Locke, Newton, Haller, Kant, Fechner, Helmholtz and du Bois-Reymond. The work of these pioneers is related to that of modern researchers in physiology, psychology, neuroscience and philosophy of mind, including: Freud, Hilary Putnam, Herbert Feigl, Gerald Edelman, Jean-Pierre Changeux, Daniel Dennett and David Chalmers, amongst others. This text appeals to researchers and advanced students in the field.
