Famous quotes containing the word nature:
“Westminster Abbey is nature crystallized into a conventional form by man, with his sorrows, his joys, his failures, and his seeking for the Great Spirit. It is a frozen requiem, with a nation’s prayer ever in dumb music ascending.”
—M. E. W. Sherwood (1826–1903)
“Flushed with new life, the crowd flows back again:
And all is tangled talk and mazy motion—
Much like a waving field of golden grain,
Or a tempestuous ocean.
And thus they give the time, that Nature meant
For peaceful sleep and meditative snores,
To ceaseless din and mindless merriment
And waste of shoes and floors.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
