In a world facing multiple crises, our foundational institutions are failing to offer effective solutions. Drawing on the emerging consilience of knowledge, Michael Pirson debunks the fundamental yet outdated assumptions of human nature that guide twentieth-century management theory and practice - as captured in the 'economistic' paradigm - and instead provides an urgently needed conceptual and practical 'humanistic' framework, based on the protection of human dignity and the promotion of well-being. By outlining the science-based pillars of this innovative system, Pirson provides a twenty first-century model for the responsible twenty first-century leader seeking sustainable ways to organize in a world of crisis. Highlighting relevant applications for research, practice, teaching and policy, this book is ideal for graduate students and professionals seeking to develop their understanding of responsible business, business ethics and corporate responsibility.
