Abstract
This paper argues that the contemporary challenge for ISUD and philosophy itself is to repair and replenish our shared and overlapping lifeworlds through the recovery, critique, clarification, and renewal of authentic values, insights, and achievements from the widest possible plurality of traditions, cultures, and philosophical visions. We must liberate the life world from the snares of creeping nihilism. We must repair and replenish the life world through open and honest communication, through philosophical dialogue among an ever-greater plurality of perspectives and points of view.
