Famous quotes containing the word nature:
“The last Night that She lived
It was a Common Night
Except the Dying—this to Us
Made Nature different”
—Emily Dickinson (1830–1886)
“She [Evelina] is a little angel!... Her face and person answer my most refined ideas of complete beauty.... She has the same gentleness in her manners, the same natural graces in her motions, that I formerly so much admired in her mother. Her character seems truly ingenuous and simple; and at the same time that nature has blessed her with an excellent understanding and great quickness of parts, she has a certain air of inexperience and innocency that is extremely interesting.”
—Frances Burney (1752–1840)
