The brief presents a model for happiness based on current knowledge in
evolutionary biology and neurobiology. Briefly, the primary purpose of
nervous systems is to direct an animal toward behaviour relevant for
survival and procreation. In primitive animals actions are based on
reflexes, while in humans the modules directing behaviour engage
positive and negative affect (good and bad feelings), and they are
swayed by cognitive processes. The reason why evolution opted for this
strategy was the improved flexibility in response - i.e., we learn from
previous experiences. The human capacity for happiness is an accidental
consequence.
An array of brain modules has evolved to care for various pursuits, but
recent studies suggest that they converge on shared neural circuits
designed to generate positive and negative mood. Happiness can be
construed as the net output of the relevant modules. The briefs suggests
a strategy for how to avoid having negative feelings (such as anxiety,
depression and chronic pain) dominate the mind, and how to exercise
positive feelings. In short, the book offers both a deeper understanding
of what happiness is about, and a framework for improving well-being.
