Descartes' Error: Emotion, Reason, and the Human Brain is a 1994 book by neurologist António Damásio, in part a treatment of the mind/body dualism question. Damásio presents the "somatic marker hypothesis", a proposed mechanism by which emotions guide (or bias) behavior and decision-making, and positing that rationality requires emotional input. He argues that René Descartes' "error" was the dualist separation of mind and body, rationality and emotion.

'Damasio argues in his well-known book that it is wrong to think that only minds think. The body and our emotions have a key role in the way we think and in rational decision-making'. Since, in his words, 'the body...contributes a content that is part and parcel of the workings of the normal mind', it follows that 'the mind is embodied, in the full sense of the term, not just embrained'.

Damasio's theory stresses 'the crucial role of feeling in navigating the endless stream of life's personal decisions....The intuitive signals that guide us in these moments come in the form of limbic-driven surges from the viscera that Damasio calls "somatic markers" - literally, gut feelings'. Listening to your gut reactions, 'the somatic marker...may lead you to reject, immediately, the negative course of action and thus...allows you to choose from among fewer alternatives '.

In Descartes' Error, Damasio also explored the way 'the neural basis of the self' as I see it, resides with the continuous activation of at least two sets of representations. One set concerns representations of key events in an individual's autobiography....The second set of representations underlying the neural self consists of the primordial representations of the individual's body'.

From these two sets, Damasio would later develop his concept of the hierarchy of consciousness, including the protoself, core consciousness, and extended consciousness - Stern's verbal self.

Damasio's book is widely acknowledged to be a 'work with far-reaching implications for understanding mental life'. Partly in consequence, there is 'at present introduced by literature such as Damasio's Descartes' Error...a trend to include (or rather rehabilitate) the body and its movement into the research of the social and behavioral sciences'.
