Torin Alter

Torin Alter presents a compelling defence of the 'knowledge argument' against physicalism, pioneered by Frank Jackson. According to physicalism, consciousness is a physical phenomenon. The knowledge argument stars Mary, who learns all objective, physical information through black-and-white media and yet acquires new information when she first sees colors for herself: information about what it is like to see in color. Based partly on that case, Jackson concludes that not all information is physical. Alter argues that the knowledge argument succeeds in refuting all standard versions of physicalism: versions on which consciousness is grounded by what objective science reveals. Alter also argues that given further, plausible assumptions, the knowledge argument leads to Russellian monism, according to which there are intrinsic properties that both constitute consciousness and underlie properties described by physics, such as mass and charge. Alter explains how the knowledge argument establishes those two conclusions and defend it against numerous objections.

From the Knowledge Argument to Russellian Monism

The Matter of Consciousness

Yujin Nagasawa

According to Russellian monism, an alternative to the familiar theories in the philosophy of mind that combines attractive components of physicalism and dualism, matter has intrinsic properties that both constitute consciousness and serve as categorical bases for the dispositional properties described in physics. Consciousness in the Physical World collects various works on Russellian monism, including historical selections, recent classics, and new pieces. Most chapters are sympathetic with the view, but some are skeptical. Together, they constitute the first book-length treatment of the view itself, its relationship to other theories, its motivations, and its problems.

Perspectives on Russellian Monism

Consciousness in the Physical World

Sven Walter

What is the nature of consciousness? How is consciousness related to brain processes? This volume collects thirteen new papers on these topics: twelve by leading and respected philosophers and one by a leading color-vision scientist. All focus on consciousness in the "phenomenal" sense: on what it's like to have an experience. Consciousness has long been regarded as the biggest stumbling block for physicalism, the view that the mind is physical. The controversy has gained focus over the last few decades, and phenomenal knowledge and phenomenal concepts--knowledge of consciousness and the associated concepts--have come to play increasingly prominent roles in this debate. Consider Frank Jackson's famous case of Mary, the super-scientist who learns all the physical information while confined in a black-and-white room. According to Jackson, if physicalism is true, then Mary's physical knowledge should allow her to deduce what it's like to see in color. Yet it seems intuitively clear that she learns something when she leaves the room. But then how can consciousness be physical? Arguably, whether this sort of reasoning is sound depends on how phenomenal concepts and phenomenal knowledge are construed. For example, some argue that the Mary case reveals something about phenomenal concepts but has no implications for the nature of consciousness itself. Are responses along these lines adequate? Or does the problem arise again at the level of phenomenal concepts? The papers in this volume engage with the latest developments in this debate. The authors' perspectives range widely. For example, Daniel Dennett argues that anti-physicalist arguments such as the knowledge argument are simply confused; David Papineau grants that such arguments at least reveal important features of phenomenal concepts; and David Chalmers defends the anti-physicalist arguments, arguing that the "phenomenal concept strategy" cannot succeed.

New Essays on Consciousness and Physicalism

Phenomenal Concepts and Phenomenal Knowledge

Robert J. Howell

Ideal for courses in consciousness and the philosophy of mind, Consciousness and The Mind-Body Problem: A Reader presents thirty-three classic and contemporary readings, organized into five sections that cover the major issues in this debate: the challenge for physicalism, physicalist responses, alternative responses, the significance of ignorance, and mental causation. Edited by Torin Alter and Robert J. Howell, the volume features work from such leading figures as Karen Bennett, Ned Block, David J. Chalmers, Frank Jackson, Colin McGinn, David Papineau, and many others.
