Famous quotes containing the word stages:
“Phlebas the Phoenician, a fortnight dead,
Forgot the cry of gulls, and the deep sea swell
And the profit and loss.
A current under sea
Picked his bones in whispers. As he rose and fell
He passed the stages of his age and youth
Entering the whirlpool.”
—T.S. (Thomas Stearns)
“The four stages of man are infancy, childhood, adolescence and obsolescence.”
—Art Linkletter (20th century)
