Famous quotes containing the words sources and/or particles:
“The sources of poetry are in the spirit seeking completeness.”
—Muriel Rukeyser (1913–1980)
“In another’s sentences the thought, though it may be immortal, is as it were embalmed, and does not strike you, but here it is so freshly living, even the body of it not having passed through the ordeal of death, that it stirs in the very extremities, and the smallest particles and pronouns are all alive with it. It is not simply dictionary it, yours or mine, but IT.”
—Henry David Thoreau (1817–1862)
