The Building Blocks of Personhood: Oliver Sacks on Neurocognitive Pillar of What Makes Us Who We Are

science

The Marginalian observes that neurologist Oliver Sacks described a patient whose severe memory loss erased his autobiographical facts, leaving him to invent countless imagined lives. Sacks wrote that the man had to "make himself and his world up every moment," highlighting how narrative fills the void of identity. The essay expands this case to argue that each of us continuously constructs a personal story through perception, feeling, thought and speech. Sacks concludes that maintaining a continuous inner narrative is essential for preserving our sense of self.
