“No person can be considered as possessing a good education without religion. A good education is that which prepares us for our future sphere of action and makes us contented with that situation in life in which God, in his infinite mercy, has seen fit to place us, to be perfectly resigned to our lot in life, whatever it may be.”
—Ann Plato (1820–?)
“At the milliners, the ladies we met were so much dressed, that I should rather have imagined they were making visits than purchases. But what diverted me most was, that we were more frequently served by men than by women; and such men! so finical, so affected! they seemed to understand every part of a woman’s dress better than we do ourselves; and they recommended caps and ribbons with an air of so much importance, that I wished to ask them how long they had left off wearing them.”
—Frances Burney (1752–1840)
