_WorldS_ ...
Karl Popper's writings describe three worlds:
World 1 -- the world of objective physical reality -- matter, vector forces, space, time
World 2 -- the world of subjective personal experience -- perception, cognition, dreams, creativity.
World 3 -- the world of externalized Objective Knowledge -- theories, methodologies, arts, facts
I might want to add a further world -- World 4 -- the spiritual dimension of life
