Famous quotes containing the words persistent and/or memory:
“The passion of self-aggrandizement is persistent but plastic; it will never disappear from a vigorous mind, but may become morally higher by attaching itself to a larger conception of what constitutes the self.”
—Charles Horton Cooley (1864–1929)
“Beauty sat bathing by a spring,
Where fairest shades did hide her;
The winds blew calm, the birds did sing,
The cool streams ran beside her.
My wanton thoughts enticed mine eye
To see what was forbidden:
But better memory said Fie;
So vain desire was chidden—”
—Anthony Munday (1553–1633)
