This is Volume III of eight in a collection on the Philosophy of the Mind and Language. Originally published in 1925, this text looks at alternative theories of life and mind at the level of enlightened common-sense; the Mind's knowledge of Existents and the Unconscious.

What are the most fundamental features of the world? Do minds stand outside the natural order? Is a unified picture of mental and physical reality possible? The Mind in Nature provides a staunchly realist account of the world as a unified system incorporating both the mental and the physical. C. B. Martin, an original and influential exponent of 'ontologically serious' metaphysics, echoes Locke's dictum that 'all things that exist are only particulars', and argues that properties are powerful qualities. He also spells out the implications of this view for philosophical conceptions of causation, intentionality, consciousness, and the mind-body problem. Martin emphasizes the importance of non-conscious 'vegetative' systems, which provide clear examples of intentionality in the form of representational use. The slide from representational use to consciousness involves a change in the material of use, but not the form of representation. A concluding chapter provides an argument for the view that an ontology of particular substances and properties leads ineluctably to monism: the bus we board with Locke takes us directly to the world of Spinoza and Einstein. Along the way, we are led to understand the nature of minds and conscious states of mind in a way that avoids both reductionism (the idea that mental is reducible to the non-mental) and dualism (the idea that mental substances or properties differ dramatically from physical substances and properties).

The modern materialist approach to life has conspicuously failed to explain such central mind-related features of our world as consciousness, intentionality, meaning, and value. This failure to account for something so integral to nature as mind, argues philosopher Thomas Nagel, is a major problem, threatening to unravel the entire naturalistic world picture, extending to biology, evolutionary theory, and cosmology. Since minds are features of biological systems that have developed through evolution, the standard materialist version of evolutionary biology is fundamentally incomplete. And the cosmological history that led to the origin of life and the coming into existence of the conditions for evolution cannot be a merely materialist history, either. An adequate conception of nature would have to explain the appearance in the universe of materially irreducible conscious minds, as such. Nagel's skepticism is not based on religious belief or on a belief in any definite alternative. In Mind and Cosmos, he does suggest that if the materialist account is wrong, then principles of a different kind may also be at work in the history of nature, principles of the growth of order that are in their logical form teleological rather than mechanistic. In spite of the great achievements of the physical sciences, reductive materialism is a world view ripe for displacement. Nagel shows that to recognize its limits is the first step in looking for alternatives, or at least in being open to their possibility.

This book explains the relationship between intelligence and environmental complexity, and in so doing links philosophy of mind to more general issues about the relations between organisms and environments, and to the general pattern of 'externalist' explanations. The author provides a biological approach to the investigation of mind and cognition in nature. In particular he explores the idea that the function of cognition is to enable agents to deal with environmental complexity. The history of the idea in the work of Dewey and Spencer is considered, as is the impact of recent evolutionary theory on our understanding of the place of mind in nature.

“I’ve gained deeper understanding listening to Rupert Spira than I have from any other exponent of modern spirituality. Reality is sending us a message we desperately need to hear, and at this moment no messenger surpasses Spira and the transformative words in his essays.” —Deepak Chopra, author of You Are the Universe, Spiritual Solutions, and Super Brain Our world culture is founded on the assumption that the Big Bang gave rise to matter, which in time evolved into the world, into which the body was born, inside which a brain appeared, out of which consciousness at some late stage developed. As a result of this “matter model,” most of us believe that consciousness is a property of the body. We feel that it is “I,” this body, that knows or is aware of the world. We believe and feel that the knowing with which we are aware of our experience is located in and shares the limits and destiny of the body. This is the fundamental presumption of mind and matter that underpins almost all our thoughts and feelings and is expressed in our activities and relationships. The Nature of Consciousness suggests that the matter model has outlived its function and is now destroying the very values it once sought to promote. For many people, the debate as to the ultimate reality of the universe is an academic one, far removed from the concerns and demands of everyday life. After all, life happens independently of our models of it. However, The Nature of Consciousness will clearly show that the materialist paradigm is a philosophy of despair and, as such, the root cause of unhappiness in individuals. It is a philosophy of conflict and, as such, the root cause of hostilities between families, communities, and nations. Far from being abstract and philosophical, its implications touch each one of us directly and intimately. An exploration of the nature of consciousness has the power to reveal the peace and happiness that truly lie at the heart of experience. Our experience never ceases to change, but the knowing element in all experience—consciousness, or what we call “I”—itself never changes. The knowing with which all experience is known is always the same knowing. Being the common, unchanging element in all experience, consciousness does not share the qualities of any particular experience: it is not qualified, conditioned, or limited by experience. The knowing with which a feeling of loneliness or sorrow is known is the same knowing with which the thought of a friend, the sight of a sunset, or the taste of ice cream is known. Just as a screen is never disturbed by the action in a movie, so consciousness is never disturbed by experience; thus it is inherently peaceful. The peace that is inherent in us—indeed that is us—is not dependent on the situations or conditions we find ourselves in. In a series of essays that draw you, through your own direct experience, into an exploration of the nature of this knowing element that each of us calls “I,” The Nature of Consciousness posits that consciousness is the fundamental reality of the apparent duality of mind and matter. It shows that the overlooking or ignoring of this reality is the root cause of the existential unhappiness that pervades and motivates most people’s lives, as well as the wider conflicts that exist between communities and nations. Conversely, the book suggests that the recognition of the fundamental reality of consciousness is the first step in the quest for lasting happiness and the foundation for world peace.

A new study of the mathematical-physical mode of cognition.

Panpsychism is the philosophical view that consciousness, mentality, or 'mindedness' in some form is fundamental in the universe. The idea has existed for centuries, but only recently has it had a serious resurgence. Galen Strawson has been on the front line of the battlefield on the topic of panpsychism since the 1990s. His paper on ‘realistic monism’, contained in this volume and originally published in 2006, is now considered something of a classic and a catalyst for panpsychism’s recent revival. This long overdue new edition of the book gives the original commentators, where they feel they have something more to add, an opportunity to update their thinking on the topic of panpsychism in general and Strawson’s realistic monism in particular. Seven new postscripts are included, which aim to enhance the original collection and push the discussion onwards. Eighteen years have passed since the first edition of this groundbreaking volume, and Strawson remains a distinctive and important voice in the field — the new edition is a must-read for all who are interested in consciousness studies.
