Was it hard for anyone else to accept the idea that emotions happen before feelings? I thought that I would point out two sections of the book that won me over.
In chapter 2, Damasio discusses a patient with parkinsonian symptoms. As part of her treatment doctors were stimulating her brain stem with electrical current. When doctors stimulated a certain area the patient began to suddenly and unexpectedly cry. Then, she reported a feeling of sadness.
In chapter 3, Damasio discusses an experiment measuring brain response to joy and sadness. Subjects were to think about emotional times in their lives. They were to make hand-signals as soon as they began feeling emotions. Subjects showed physiological responses before indicating with a hand movement that they were feeling sad or joyful.
This is a brief summary of the two sections that convinced me. I would suggest reading or re-reading these sections from the book for more clarification.
