Darkness, as polar to brightness, is understood to be an absence of visible light. It is also the appearance of black in a color space.
Humans are unable to distinguish color when either light or darkness predominate (W. Wundt, Outlines of Psychology, 1907). In the absence of light, perception is achromatic and ultimately, black.
The emotional response to darkness has metaphorical connotations in many cultures.
Famous quotes containing the word darkness:
“We must understand how to hide in darkness in order to escape the gnat-swarms of utterly annoying admirers.”
—Friedrich Nietzsche (1844–1900)
“Out of the darkness where Philomela sat,
Her fairy numbers issued. What then ailed me?
My ears are called capacious but they failed me,
Her classics registered a little flat!
I rose, and venomously spat.”
—John Crowe Ransom (1888–1974)
“Runs falls rises stumbles on from darkness into darkness
and the darkness thicketed with shapes of terror
and the hunters pursuing and the hounds pursuing
and the night cold and the night long and the river
to cross and the jack-muh-lanterns beckoning beckoning
and blackness ahead”
—Robert Earl Hayden (1913–1980)
