This book presents quantum theory as a theory based on new relationships among matter, thought, and experimental technology, as against those previously found in physics, relationships that also redefine those between mathematics and physics in quantum theory. The argument of the book is based on its title concept, reality without realism (RWR), and in the corresponding view, the RWR view, of quantum theory. The book considers, from this perspective, the thinking of Bohr, Heisenberg, Schrödinger, and Dirac, with the aim of bringing together the philosophy and history of quantum theory. With quantum theory, the book argues, the architecture of thought in theoretical physics was radically changed by the irreducible role of experimental technology in the constitution of physical phenomena, accordingly, no longer defined independently by matter alone, as they were in classical physics or relativity. Or so it appeared. For, quantum theory, the book further argues, made us realize that experimental technology, beginning with that of our bodies, irreducibly shapes all physical phenomena, and thus makes us rethink the relationships among matter, thought, and technology in all of physics.

A daring new vision of the quantum universe, and the scandals controversies, and questions that may illuminate our future--from Canada's leading mind on contemporary physics. Quantum physics is the golden child of modern science. It is the basis of our understanding of atoms, radiation, and so much else, from elementary particles and basic forces to the behaviour of materials. But for a century it has also been the problem child of science, plagued by intense disagreements between its intellectual giants, from Albert Einstein to Stephen Hawking, over the strange paradoxes and implications that seem like the stuff of fantasy. Whether it's Schrödinger's cat--a creature that is simultaneously dead and alive--or a belief that the world does not exist independently of our observations of it, quantum theory is what challenges our fundamental assumptions about our reality. In Einstein's Unfinished Revolution, globally renowned theoretical physicist Lee Smolin provocatively argues that the problems which have bedeviled quantum physics since its inception are unsolved for the simple reason that the theory is incomplete. There is more, waiting to be discovered. Our task--if we are to have simple answers to our simple questions about the universe we live in--must be to go beyond it to a description of the world on an atomic scale that makes sense. In this vibrant and accessible book, Smolin takes us on a journey through the basics of quantum physics, introducing the stories of the experiments and figures that have transformed the field, before wrestling with the puzzles and conundrums that they present. Along the way, he illuminates the existing theories about the quantum world that might solve these problems, guiding us toward his own vision that embraces common sense realism. If we are to have any hope of completing the revolution that Einstein began nearly a century ago, we must go beyond quantum mechanics as we know it to find a theory that will give us a complete description of nature. In Einstein's Unfinished Revolution, Lee Smolin brings us a step closer to resolving one of the greatest scientific controversies of our age.

At the heart of Immanuel Kant's critical philosophy is an epistemological and metaphysical position he calls transcendental idealism; the aim of this book is to understand this position. Despite the centrality of transcendental idealism in Kant's thinking, in over two hundred years since the publication of the first Critique there is still no agreement on how to interpret the position, or even on whether, and in what sense, it is a metaphysical position. Lucy Allais argue that Kant's distinction between things in themselves and things as they appear to us has both epistemological and metaphysical components. He is committed to a genuine idealism about things as they appear to us, but this is not a phenomenalist idealism. He is committed to the claim that there is an aspect of reality that grounds mind-dependent spatio-temporal objects, and which we cannot cognize, but he does not assert the existence of distinct non-spatio-temporal objects. A central part of Allais's reading involves paying detailed attention to Kant's notion of intuition, and its role in cognition. She understands Kantian intuitions as representations that give us acquaintance with the objects of thought. Kant's idealism can be understood as limiting empirical reality to that with which we can have acquaintance. He thinks that this empirical reality is mind-dependent in the sense that it is not experience-transcendent, rather than holding that it exists literally in our minds. Reading intuition in this way enables us to make sense of Kant's central argument for his idealism in the Transcendental Aesthetic, and to see why he takes the complete idealist position to be established there. This shows that reading a central part of his argument in the Transcendental Deduction as epistemological is compatible with a metaphysical, idealist reading of transcendental idealism.

This book defends a radical new theory of contingency as a physical phenomenon. Drawing on the many-worlds approach, it argues that quantum theories are best understood as telling us about the space of genuine possibilities, rather than as telling us solely about actuality.

A leading philosopher takes a mind-bending journey through virtual worlds, illuminating the nature of reality and our place within it. Virtual reality is genuine reality; that’s the central thesis of Reality+. In a highly original work of “technophilosophy,” David J. Chalmers gives a compelling analysis of our technological future. He argues that virtual worlds are not second-class worlds, and that we can live a meaningful life in virtual reality. We may even be in a virtual world already. Along the way, Chalmers conducts a grand tour of big ideas in philosophy and science. He uses virtual reality technology to offer a new perspective on long-established philosophical questions. How do we know that there’s an external world? Is there a god? What is the nature of reality? What’s the relation between mind and body? How can we lead a good life? All of these questions are illuminated or transformed by Chalmers’ mind-bending analysis. Studded with illustrations that bring philosophical issues to life, Reality+ is a major statement that will shape discussion of philosophy, science, and technology for years to come.

This study recapitulates basic developments in the tradition of hermeneutic and phenomenological studies of science. It focuses on the ways in which scientific research is committed to the universe of interpretative phenomena. It treats scientific research by addressing its characteristic hermeneutic situations, and uses the following basic argument in this treatment: By demonstrating that science’s epistemological identity is not to be spelled out in terms of objectivism, mathematical essentialism, representationalism, and foundationalism, one undermines scientism without succumbing scientific research to “procedures of normative-democratic control” that threaten science’s cognitive autonomy. The study shows that in contrast to social constructivism, hermeneutic phenomenology of scientific research makes the case that overcoming scientism does not imply restrictive policies regarding the constitution of scientific objects.

Dealing with the controversies over the reality of the external world, this work offers a defense of realism, a critique of various forms of contemporary anti-realism, and a sketch of the author's version of realism, namely hylorealism. It examines the main varieties of antirealism and argues that all of these in fact hinder scientific research.
