Famous quotes containing the word growth:
“The risk for a woman who considers her helpless children her “job” is that the children’s growth toward self-sufficiency may be experienced as a refutation of the mother’s indispensability, and she may unconsciously sabotage their growth as a result.”
—Letty Cottin Pogrebin (20th century)
“Rights! There are no rights whatever without corresponding duties. Look at the history of the growth of our constitution, and you will see that our ancestors never upon any occasion stated, as a ground for claiming any of their privileges, an abstract right inherent in themselves; you will nowhere in our parliamentary records find the miserable sophism of the Rights of Man.”
—Samuel Taylor Coleridge (1772–1834)
