The Self is a Constructed Necessity:

The "self" is not a fixed entity but a dynamic, adaptive fiction—an emergent phenomenon built atop the scaffolding of biology, memory, emotion, and social interaction. It is a narrative architecture, constantly edited and revised in response to new inputs and environmental pressures. You are not a thing but a process: the ongoing improvisation of identity, stitched together moment by moment by a brain trying to make sense of the chaos around—and within—it.
In essence, the self is a user interface: a simplified, intuitive model that allows complex biological systems to operate coherently in a social world. It is not objective reality—it is functional illusion.
