”A person afraid of the dark is superior to a person afraid of the light.” —Hippokrites
Fear of the dark is innate and entirely natural. So it takes exceptional courage to explore the darkness and shine a light on what is hidden there. Many of the great writers have done just that, and they are like the early explorers who dared to go where “there be dragons”.
