Looking for Spinoza: Joy, Sorrow, and the Feeling Brain

Leaving out appraisal also would render the biological description of the phenomena of emotion vulnerable to the caricature that emotions without an appraisal phase are meaningless events. It would be more difficult to see how beautiful and amazingly intelligent emotions can be, and how powerfully they can solve problems for us.

The doctors found one electrode contact that greatly relieved the woman's symptoms. But the unexpected happened when the electric current passed through one of the four contact sites on the patient's left side, precisely two millimeters below the contact that improved her condition. The patient stopped her ongoing conversation quite abruptly, cast her eyes down and to her right side, then leaned slightly to the right and her emotional expression became one of sadness. After a few seconds she suddenly began to cry. Tears flowed and her entire demeanor was one of profound misery. Soon she was sobbing. As this display continued she began talking about how deeply sad she felt, how she had no energies left to go on living in this manner, how hopeless and exhausted she was. [ . . . ]The physician in charge of the treatment realized that this unusual event was due to the current and aborted the procedure. About ninety seconds after the current was interrupted the patient's behavior returned to normal. [ . . . ]Why would this patient's brain evoke the kind of thoughts that normally cause sadness considering that the emotion and feeling were unmotivated by the appropriate stimuli? The answer has to do with the dependence of feeling on emotion and the intriguing ways of one's memory. When the emotion sadness is deployed, feelings of sadness instantly follow. In short order, the brain also brings forth the kind of thoughts that normally cause the emotion sadness and feelings of sadness. This is because associative learning has linked emotions with thoughts in a rich two-way network. Certain thoughts evoke certain emotions and vice-versa.

Moreover, understanding what feelings are, how they work, and what they mean is indispensable to the future construction of a view of human beings more accurate than the one currently available, a view that would take into account advances in the social sciences, cognitive science, and biology. Why is such a construction of any practical use? Because the success or failure of humanity depends in large measure on how the public and the institutions charged with the governance of public life incorporate that revised view of human beings in principles and policies.

La historia de nuestra civilización es, hasta cierto punto, la historia de un esfuerzo persuasivo por extender los mejores «sentimientos morales» a círculos cada vez más amplios de humanidad,
