The waking have one world in common; sleepers have each a private world of his own

Heraclitus, the ancient Greek philosopher known for his doctrine of change and the unity of opposites, believed in the interconnectedness of all things in the universe. His famous quote, "The waking have one world in common; sleepers have each a private world of his own," reflects his belief in the dual nature of reality and the different states of consciousness that human beings experience.
