Famous quotes containing the words general and/or feature:
“The reputation of generosity is to be purchased pretty cheap; it does not depend so much upon a mans general expense, as it does upon his giving handsomely where it is proper to give at all. A man, for instance, who should give a servant four shillings, would pass for covetous, while he who gave him a crown, would be reckoned generous; so that the difference of those two opposite characters, turns upon one shilling.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (16941773)
“With men he can be rational and unaffected, but when he has ladies to please, every feature works.”
—Jane Austen (17751817)
