Famous quotes containing the word nature:
“Poor shad! where is thy redress? When Nature gave thee instinct, gave she thee the heart to bear thy fate? Still wandering the sea in thy scaly armor to inquire humbly at the mouths of rivers if man has perchance left them free for thee to enter.”
—Henry David Thoreau (1817–1862)
“For Nature ever faithful is
To such as trust her faithfulness.
When the forest shall mislead me,
When the night and morning lie,
When the sea and land refuse to feed me,
‘Twill be time enough to die.”
—Ralph Waldo Emerson (1803–1882)
