Famous quotes containing the words related and/or ideas:
“In the middle years of childhood, it is more important to keep alive and glowing the interest in finding out and to support this interest with skills and techniques related to the process of finding out than to specify any particular piece of subject matter as inviolate.”
—Dorothy H. Cohen (20th century)
“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)
