Martha C. Nussbaum is one of the great contemporary philosophers and this book an interesting application of her thoughts around emotion in relation to the recent political environment in the United States. Nussbaum analyses how a few primal emotions are having dramatic impact on the way society is developing and how this is influencing the way people vote. As you can probably tell from the title one of these emotions is fear; but Nussbaum also includes anger, envy, and hope. Each chapter starts off defining and contextualizing the emotion (or social construct) and then provides an analysis of how this is being demonstrated in society, what the impacts may be, and also some recommendations on how to address the challenges or harness the benefits of the emotion. If you've never read anything by Nussbaum before, or if you're interested in political/social philosophy, this is a fantastic book.
