A leading psychologist and philosopher challenge rational choice theory, arguing that we should instead see our choices as influenced by a “constellation of virtues,” allowing for a far richer understanding of the decisions we make and helping us to live more integrated and purposeful lives. Drawing from economics, psychology, and philosophy - and both inspired by and challenging Daniel Kahneman’s Thinking, Fast and Slow - they show how the focus on rationality, narrowly understood, fails to fully describe how we think about our decisions, much less help us make better ones.
