In popular cultures, "Extraterrestrials" are life forms — especially intelligent life forms— that are of extraterrestrial origin (often also called "aliens").
Famous quotes containing the words life and/or culture:
“The forest waves, the morning breaks,
The pastures sleep, ripple the lakes,
Leaves twinkle, flowers like persons be
And life pulsates in rock or tree.”
—Ralph Waldo Emerson (1803–1882)
“Ours is a culture based on excess, on overproduction; the result is a steady loss of sharpness in our sensory experience. All the conditions of modern life—its material plenitude, its sheer crowdedness—conjoin to dull our sensory faculties.”
—Susan Sontag (b. 1933)
