The Feeling of What Happens: Body and Emotion in the Making of Consciousness

Damasio's central claim is that consciousness is not a disembodied computational process but arises from the brain's continuous mapping of the body's internal states. He rejects the assumption, common in cognitive science, that consciousness can be understood purely in terms of information processing in the brain, independent of the body's regulatory functions. As Raymond Dolan noted in Nature, Damasio provides 'the first truly compelling neurobiological account of the self' [citation:3]. The book argues that the self has a 'preconscious biological precedent, the protoself,' which corresponds to a coherent collection of neural patterns mapping the moment-by-moment physical state of the organism [citation:3]. Consciousness emerges when this proto-self is modified by an object and the brain generates a second-order representation of that modification.

The book introduces a series of foundational distinctions. Core consciousness is the simple, biological phenomenon we share with some nonhuman animals, scoped to the Here and Now and independent of language and working memory [citation:1]. Extended consciousness is the awareness of being situated within an individual history, involving anticipated futures and a lived past [citation:1]. The core self is 'ceaselessly re-created for each and every object with which the brain interacts'—transient and continuously regenerated [citation:1]. The autobiographical self is built from systematic records of memories, name, and invariant properties, generating the subjective experience of transtemporal identity [citation:1]. Damasio also distinguishes emotion (bodily responses) from feeling (the mental experience of those responses) [citation:10].

The book received widespread acclaim. Raymond Dolan, reviewing in Nature, called it 'a stunning book' that provides 'the first truly compelling neurobiological account of the self' and praised its 'astonishing boldness' in grappling with questions most neuroscientists dismiss as intractable [citation:3]. The Library of Congress publisher description hailed it as 'a magnificent work of ingenious science, a gorgeously written book' [citation:19]. A review in Perception noted that Damasio 'discusses what he does and doesn't mean by consciousness with great care' and that the book is 'a success' [citation:4]. However, some critics questioned whether the theory fully resolves the mind-body problem or whether the concept of emotion is defined consistently throughout.

The Feeling of What Happens extends the argument of Descartes' Error (1994), where Damasio had revealed 'the critical importance of emotion in the making of reason' [citation:19]. Where the earlier book focused on the role of emotion and the body in decision-making, the 1999 book turns to the question of consciousness itself. Damasio builds on the somatic marker hypothesis—the idea that bodily states bias decision-making—to propose a biological account of how the sense of self arises from the brain's mapping of the body. The core self, in this account, is the felt presence of the organism in the act of knowing, a direct extension of the embodied perspective developed in the earlier work.

The body is central to Damasio's account. He argues that 'the body, as represented in the brain, may constitute the indispensable frame of reference for the neural processes that we experience as the mind' [citation:5]. The proto-self is a coherent collection of neural patterns that map, moment by moment, the physical state of the organism [citation:3]. Consciousness arises when this proto-self is altered by an object and the brain creates a second-order mapping of that alteration. Without the body as a reference point, Damasio argues, there can be no stable sense of self and no consciousness as we know it. Critics have noted, however, that it is 'not the body that Damasio identifies as the ground reference but its representation,' which raises questions about whether this truly avoids a form of dualism [citation:5].

A frequent misconception is that Damasio claims consciousness is simply the feeling of bodily states—that emotions and consciousness are identical. In fact, Damasio distinguishes carefully between emotion (bodily responses such as changes in heart rate, posture, and facial expression) and feeling (the mental experience of those bodily changes) [citation:10]. Consciousness is not the emotion itself but the feeling of the emotion, and crucially, the knowing that one is having that feeling. As one review put it, Damasio's concern is 'with possession of a sense of self, with the ability to know that you are the subject of your feelings' [citation:4]. Another misreading treats the core self as a homunculus; Damasio explicitly avoids this by grounding the self in biological regulation rather than a central controller.
