The project “Spirited Existential Constitutionalism” explores the interplay between existential thought and constitutional law, positing that constitutions serve as dynamic expressions of human essence. By integrating insights from philosophers like Sartre, Camus, and Kierkegaard, the framework addresses the existential dilemmas of authenticity and meaning within various cultural narratives. The aim is for an interdisciplinary assessment of constitutional integrity through “existential audits” and to highlight spirituality in legal frameworks across different jurisdictions, from the U.S. to India. In light of contemporary crises, it advocates for a global constitutional spirituality that embraces rights as existential commitments fostering collective reconciliation.
