Famous quotes containing the word advancement:
“As the saffron tints and crimson flushes of morn herald the coming day, so the social and political advancement which woman has already gained bears the promise of the rising of the full-orbed sun of emancipation. The result will be not to make home less happy, but society more holy.”
—Frances Ellen Watkins Harper (1825–1911)
