Feeling Our Emotions

According to noted neurologist Antonio R. Damasio, joy or sorrow can emerge only after the brain registers physical changes in the body



In recent years, Damasio has become increasingly interested in the role emotions play in our decision-making processes and in our self-image. In several widely popular books, he has shown how certain feelings are cornerstones of our survival. And today he argues that our internal, emotional regulatory processes not only preserve our lives but actually shape our greatest cultural accomplishments.

MIND: Professor Damasio, why are you so fascinated by the nature of human emotion?

Antonio R. Damasio: At first I was interested in all types of neurological injuries. If one area of the brain would lose its ability to function, the patient's behavior could change either dramatically or only subtly. One day I asked myself, What is missing in a person who can pass an intelligence test with flying colors but can’t even organize his own life? Such patients can hold their own in completely rational arguments but fail, for example, to avoid a situation involving unnecessary risk. These kinds of problems mainly occur after an injury to the forebrain. As our tests prove, the result is a lack of normal emotional reactions. I continue to be fascinated by the fact that feelings are not just the shady side of reason but that they help us to reach decisions as well.

MIND: You differentiate between feelings and emotions. How so?


MIND: So, then, feelings are formed by emotions?

Damasio: Yes. The brain is constantly receiving signals from the body, registering what is going on inside of us. It then processes the signals in neural maps, which it then compiles in the so-called somatosensory centers. Feelings occur when the maps are read and it becomes apparent that emotional changes have been recorded—as snapshots of our physical state, so to speak.

MIND: According to your definition, all feelings have their origin in the physical. Is that really the case?

Damasio: Interestingly enough, not all feelings result from the body's reaction to external stimuli. Sometimes changes are purely simulated in the brain maps. For example, when we feel sympathy for a sick person, we re-create that person's pain to a certain degree internally. Also, the mapping of our physical state is never completely exact. Extreme stress or extreme fear and even physical pain can be dismissed; the brain ignores the physical signals that are transmitting the pain stimulus.

MIND: The differentiation between emotions and feelings brings to mind 17th-century philosopher René Descartes’ idea of dualism—that the body and mind represent autonomous systems. But you reject that idea, as you explain in your book Descartes' Error. How should we see the relationship between mind and body?
