Introduction: Fragmentation of the Unus Mundus

:  This panel is a series of presentations by a father and his three sons. The first is a critique of the concept of the  Unus Mundus , an idea that goes back at least as far as Plato's Cave in western intellectual history. A longing for unchanging foundational ideas lies at the core of much of our culture, psychology, and theology. The subsequent presentations describe various unforeseen, destructive results stemming from the perspective of the  Unus Mundus . The first example is of persons with Alzheimer's disease, whose singular subjectivity is often ignored because they are seen as a category. They are ‘Alzheimer‐ed’, subtly enabling those around them to avoid an anxiety‐producing encounter with their enigmatic otherness. Another important perspective is the modernist re‐construction of city spaces that has resulted in the loss of an organic sense of containment. The lengthy horizon of the grand boulevards seemed like openings upon infinity, often provoking panic and agoraphobia, as seen in the work of Edvard Munch. Lastly, the genocidal tendencies of modern times epitomize the dangers of totalizing, Utopian ideas. Violent elimination may be visited upon groups or peoples who are deemed ‘impure’, as besmirching idealized social visions. Such examples illustrate some of the ethical dangers of conceptualizations related to the  Unus Mundus .
