Each of us lives within the universe - the prison - of his own brain. Projecting from it are millions of fragile sensory nerve fibers, in groups uniquely adapted to sample the energetic states of the world around us: heat, light, force, and chemical composition. That is all we ever know of it directly; all else is logical inference.

Our understanding of the universe is limited to our brain's perceptions and interpretations.
This quote highlights the notion that our experience of the universe is confined to the interpretations made by our brain through sensory input.
