It would be good if we could somehow insulate our passions from our reasoning powers; and to some extent we can. Some people are quite good at compartmentalizing their emotions. Often, however, they don’t have very strong emotions in the first place. They may get what they want, but they do not want very much. Granting supreme importance to cognitive rationality is achieved at the cost of not having much they want to be rational about.
