Emily Cataneo’s review finds the theory ambitious and engaging, but also dense, repetitive, and short on everyday examples.

Damasio is a neuroscientist and professor whose previous books include Descartes’ Error and Feeling & Knowing. Cataneo’s article is a review of his argument, not an experimental test of whether his theory is correct.

Homeostasis comes first
Homeostasis is the ongoing regulation that helps an organism maintain internal conditions. The body adjusts processes such as blood pressure without requiring conscious deliberation. Damasio’s account, as Cataneo presents it, asks what happens when automatic regulation is not enough and an organism must respond to a need or threat.
#1 Best Overall
In his view, feelings such as hunger, thirst, pain, and exhaustion make bodily conditions matter to the organism and help guide action. These homeostatic feelings are not simply the result of advanced cognition. Damasio proposes that they helped provide the groundwork from which conscious experience developed.
This is the book’s central reversal: instead of treating consciousness as a product of high-level thought that later generates feelings, Damasio places bodily feeling and regulation near the beginning of the story. As he puts it in a passage quoted by Cataneo, “Trying to find the source of consciousness in a dedicated ‘consciousness-making’ device is futile.”
Rank #2
Four parts of the mind in the book’s framework
Cataneo describes Damasio’s account through several conceptual distinctions. They are components of his framework, not universally agreed scientific categories.
- Feeling Mind: relates to processes in the body and the feelings associated with them.
- Perceptual Mind: concerns the surrounding world.
- Reflective/Linguistic Mind: supports reflection and memory.
- Integrated Mind: brings processes together.
Interoception—the monitoring of the body’s internal state—supports the Feeling Mind in this account. That emphasis makes the body-brain relationship central: consciousness is not explained as a detached mental function operating independently of bodily life.
What does the book say about AI and other forms of life?
Damasio extends his account to plant and bacterial sensing, as well as the emotional and social consequences of mind-body processes. Cataneo also reports that he argues today’s AI lacks a living body and therefore lacks the vulnerability and homeostatic feelings that, in his theory, ground consciousness.
He suggests that giving AI something like vulnerability might constrain dangerous behavior. That is a speculative proposal, not an established result or a settled conclusion about machine consciousness. The claim follows from Damasio’s premise that consciousness depends on living bodily regulation; it should not be mistaken for consensus across AI or consciousness research.
Rank #4
What does the reviewer think of the book?
Cataneo sees intellectual ambition and passages she finds convincing, along with a strong sense of Damasio’s emotional investment in a theory developed over a long career. She also says the complexity, repeated restatements, and slow stretches can frustrate readers. In her view, more examples drawn from ordinary life would have made the detailed physiology easier to grasp. She finds a kind of charm in the repetition, too, because it conveys the author’s excitement.

The book’s evolutionary framing sits within a field where researchers have not settled on a detailed general theory of consciousness. A 2025 methodological article in Cognitive Science argues that evolutionary reasoning should not serve as the foundational evidence for claims about consciousness. It says hypotheses should be assessed primarily against evidence from present-day humans and animals, while evolution remains useful for generating hypotheses and providing supporting context. This is methodological guidance, not a direct rebuttal of Damasio’s book.
That distinction is useful for readers: Damasio offers a theory about how bodily feeling may have contributed to consciousness over evolutionary time, while the methodological argument cautions that an evolutionary story alone cannot establish whether a consciousness hypothesis is true. Read the 2025 methodological article in PubMed Central.
Who is this book for?
Readers interested in embodied cognition, neuroscience, and theories of consciousness may value Damasio’s attempt to place homeostasis and feeling at the center of the discussion. The book may be a tougher fit for anyone seeking a concise introduction or a steady stream of familiar, concrete examples: Cataneo’s review specifically flags its dense exposition, repetition, and slow passages. Its claims about AI are best read as implications of Damasio’s position, not as a verdict on what machines can or cannot become.
