Meeting the Universe Halfway : Quantum Physics and the Entanglement of Matter and Meaning

""Meeting the Universe Halfway" is highly original, exciting, and important. In this book Karen Barad puts her expertise in feminist studies and quantum physics to superb use, offering agential realism as an important alternative to representationalism."--Arthur Zajonc, coauthor of "The Quantum Challenge: Modern Research on the Foundation of Quantum Mechanics"

Elaborating the author's theory of agential realism, this book offers an account of the world as a whole rather than as composed of separate natural and social realms. It analyses the philosophical framework of quantum physicist Niels Bohr, extending Bohr's philosophical views in light of scholarship in physics, and the philosophy of science.

"Meeting the Universe Halfway is highly original, exciting, and important. In this book Karen Barad puts her expertise in feminist studies and quantum physics to superb use, offering agential realism as an important alternative to representationalism."-Arthur Zajonc, coauthor of The Quantum Challenge: Modern Research on the Foundation of Quantum Mechanics "Meeting the Universe Halfway is the most important and exciting book in science studies that I have read in a long time. Karen Barad provides an original and satisfying response to a perennial problem in philosophy and cultural theory: how to grasp matter and meaning or causality and discourse together, without either erasing one of them or introducing an unbridgeable dualism. These theoretical abstractions come alive in Barad's vivid examples; she shows that uncompromisingly rigorous analysis of difficult theoretical issues need not sacrifice concreteness or accessibility. Her methodological lessons from the diffraction of light and her convincing interpretations of familiar puzzles and recent experimental results in quantum physics also display how science and science studies can genuinely learn from one another. What other book could be a 'must read' in such diverse fields as science studies, foundations of quantum mechanics, feminist and queer theory, and philosophical metaphysics and epistemology?"-Joseph Rouse, Wesleyan University "Karen Barad's Meeting the Universe Halfway makes fundamental contributions to science studies, philosophy, feminist theory, and physics-it is a rare book that can do that. This is an important, ambitious, readable, risk-taking, and very smart book, one to savor and grow with. Barad elaborates Niels Bohr's philosophy-physics in the light of feminist science studies to propose an account of material-discursive practices in scientific knowledge. Eschewing all romantic appropriations of quantum physics that evade strong knowledge claims, Barad argues that Bohr's interpretation of the experimental-theoretical nexus of quantum mechanics is crucial to understanding how observations and agencies of observation cannot be independent. 'Agencies of observation' are not liberal opinion-bearers, but situated entities made up of humans and non-humans in specific relationship. Reality is not independent of our explorations of it; and reality is not a matter of opinion, but of the material consequences of some cuts and not others made in the fabric of the world. As Barad reminds us, identities are always formed in intra-action. Ethical practices and consequences are intrinsic to the web. These issues are at the heart of debates about 'constructivism,' 'realism,' and the import of science studies, including feminist science studies, for configuring the nature of objective knowledge and the kinds of authorized actors in public worlds deeply shaped by science and technology."-Donna Haraway, author of Modest_Witness@Second_Millennium.FemaleMan (c)_Meets_OncoMouse (TM): Feminism and Technoscience "Meeting the Universe Halfway is an ambitious, thought-provoking, challenging book. . . . The book is a provocative, generative, contribution to our attempts to provide effective tools to describe and understand the rapidly changing world we are part of. It deserves wide analysis and discussion. My intent here is to argue that it merits the serious attention of historians, philosophers, sociologists of science, and science studies and STS scholars." -- S. S. Schweber * ISIS *
