Famous quotes containing the word power:
“it is a power of
strong enchantment. It
is like the dove-
neck animated by
sun; it is memory’s eye;
it’s conscientious inconsistency.”
—Marianne Moore (1887–1972)
“Though I than He—may longer live
He longer must—than I—
For I have but the power to kill,
Without—the power to die—”
—Emily Dickinson (1830–1886)
“But the nature of our civilized minds is so detached from the senses, even in the vulgar, by abstractions corresponding to all the abstract terms our languages abound in, and so refined by the art of writing, and as it were spiritualized by the use of numbers, because even the vulgar know how to count and reckon, that it is naturally beyond our power to form the vast image of this mistress called “Sympathetic Nature.””
—Giambattista Vico (1688–1744)
