Book excerpt: Freud wrote that the greatest problem facing humanity is its destructive urge. There is no one factor that solves the issue. The Challenge of Being Human explores tendencies that make us up and capacities that try to meet them. The shock of ourselves is perennial. We are challenged by our own aliveness and a need to open doors as yet unknown. We are not done evolving, growing, learning, feeling, caring. Growth of capacity to tolerate and work with experience is part of our evolutionary challenge. This book seeks to support us in whatever ways we can begin to meet this challenge.
