Can we trust our senses to tell us the truth? Challenging leading scientific theories that claim that our senses report back objective reality, cognitive scientist Donald Hoffman argues that while we should take our perceptions seriously, we should not take them literally. From examining why fashion designers create clothes that give the illusion of a more “attractive” body shape to studying how companies use color to elicit specific emotions in consumers, and even dismantling the very notion that spacetime is objective reality, The Case Against Reality dares us to question everything we thought we knew about the world we see.

In an informal style replete with illustrations, Hoffman presents the compelling scientific evidence for vision's constructive powers unveiling a grammar of vision--a set of rules that govern our perception of line, color, form, depth, and motion. 150 illustrations, 20 in color.

Observer Mechanics: A Formal Theory of Perception provides information pertinent to the fundamental aspects of perception. This book provides an approach to the study of perception that attempts to be both general and rigorous. Organized into 10 chapters, this book begins with an overview of the structure of perceptual capacity. This text then presents the relationship between observers and Turing machines. Other chapters provide a formal framework in which to describe an observer and its objects of perception, and then develop from this framework a perceptual dynamics. This book discusses as well the conditions in which an observer may be said to perceive truly and discusses how stabilities in perceptual dynamics might permit the genesis of higher level observers. The final chapter deals with the relationship between the formalisms of quantum mechanics and observer mechanics. This book is a valuable resource for physicists, psychophysicists, philosophers, cognitive scientists, and perceptual psychologists.

NEW YORK TIMES BESTSELLER "If you’ve ever wondered how you have the capacity to wonder, some fascinating insights await you in these pages.” --Adam Grant, New York Times bestselling author of Originals As concise and enlightening as Seven Brief Lessons on Physics and Astrophysics for People in a Hurry, this mind-expanding dive into the mystery of consciousness is an illuminating meditation on the self, free will, and felt experience. What is consciousness? How does it arise? And why does it exist? We take our experience of being in the world for granted. But the very existence of consciousness raises profound questions: Why would any collection of matter in the universe be conscious? How are we able to think about this? And why should we? In this wonderfully accessible book, Annaka Harris guides us through the evolving definitions, philosophies, and scientific findings that probe our limited understanding of consciousness. Where does it reside, and what gives rise to it? Could it be an illusion, or a universal property of all matter? As we try to understand consciousness, we must grapple with how to define it and, in the age of artificial intelligence, who or what might possess it. Conscious offers lively and challenging arguments that alter our ideas about consciousness—allowing us to think freely about it for ourselves, if indeed we can.

A rigorous case for the primacy of mind in nature, from philosophy to neuroscience, psychology and physics. The Idea of the World offers a grounded alternative to the frenzy of unrestrained abstractions and unexamined assumptions in philosophy and science today. This book examines what can be learned about the nature of reality based on conceptual parsimony, straightforward logic and empirical evidence from fields as diverse as physics and neuroscience. It compiles an overarching case for idealism - the notion that reality is essentially mental - from ten original articles the author has previously published in leading academic journals. The case begins with an exposition of the logical fallacies and internal contradictions of the reigning physicalist ontology and its popular alternatives, such as bottom-up panpsychism. It then advances a compelling formulation of idealism that elegantly makes sense of - and reconciles - classical and quantum worlds. The main objections to idealism are systematically refuted and empirical evidence is reviewed that corroborates the formulation presented here. The book closes with an analysis of the hidden psychological motivations behind mainstream physicalism and the implications of idealism for the way we relate to the world.

Does the real world, defined as a world of objects that exist independent of human interests, concerns, and cognitive activities, really exist? Jan Westerhoff argues that we have good reason to believe it does not. His discussion considers four main facets of the idea of the real world, ranging from the existence of a separate external and internal world (comprising various mental states congregated around a self), to the existence of an ontological foundation that grounds the existence of all the entities in the world, and the existence of an ultimately true theory that provides a final account of all there is. As Westerhoff discusses the reasons for rejecting the postulation of an external world behind our representations, he asserts that the internal world is not as epistemically transparent as is usually assumed, and that there are good reasons for adopting an anti-foundational account of ontological dependence. Drawing on conclusions from the ancient Indian philosophical system of Madhyamaka Buddhism, Westerhoff defends his stance in a purely Western philosophical framework, and affirms that ontology, and philosophy more generally, need not be conceived as providing an ultimately true theory of the world.

Argues that the key to understanding ourselves and consciousness is the "strange loop," a special kind of abstract feedback loop that inhabits the brain.
