Antonio Damasio

Biography

Portuguese-American neuroscientist whose work on patients with brain injuries gave empirical weight to what phenomenologists had argued philosophically: that emotion is not the enemy of reason but its necessary foundation. His patients with ventromedial prefrontal damage kept their intelligence intact and tested normally on reasoning and even moral-judgment tasks, but the emotional response that had accompanied their choices was gone, and they could no longer decide anything, down to which restaurant to eat at. Reason stripped of feeling did not get purer. It stopped working. Head of the Brain and Creativity Institute at USC.

Key Ideas

The somatic marker hypothesis: emotions guide decision-making through bodily signals.The feeling of what happens: consciousness from the organism's sense of its body.Core self vs. autobiographical self.Homeostasis as the foundation of feeling.

Clinical Relevance

Damasio put neurological evidence behind what Merleau-Ponty argued philosophically: cognition without embodiment is impaired, not purified. The somatic marker hypothesis holds that the body tags experiences with emotional valence and that those tags guide later decisions. It is still a hypothesis, and the Iowa Gambling Task evidence for it has been seriously contested, but it remains the best-developed account of what clinicians are pointing at when a client 'has a gut feeling' about something. His distinction between the core self (a pre-reflective, body-based sense of being) and the autobiographical self (the narrative constructed from memory) is what body-based therapies are implicitly claiming when they say they reach what talk therapy cannot: they work at the level of core self, beneath narrative. For trauma clients, the autobiographical self may have a coherent story while the core self still carries the body's unresolved response.
