To be always thinking about your manners is not the way to make them good; the very perfection of manners is not to think about yourself
Richard Whately
Manners are especially the need of the plain. The pretty can get away with anything.
Evelyn Waugh
Good manners are made up of petty sacrifices
Ralph Waldo Emerson
Manners are of more importance than laws... Manners are what vex or soothe, corrupt or purify, exalt or debase, barbarize or refine us, by a constant, steady, uniform, insensible operation, like that of the air we breathe in.
Edmund Burke
A man's own manner and character is what most becomes him.
Cicero
Learn young about hard work and manners - and you'll be through the whole dirty mess and nicely dead again before you know it.
F. Scott Fitzgerald
Good manners can replace morals. It may be years before anyone knows if what you are doing is right. But if what you are doing is nice, it will be immediately evident.
P.J. O'Rourke
There are men whose manners have the same essential splendor as the simple and awful sculpture on the friezes of the Parthenon, and the remains of the earliest Greek art.
Ralph Waldo Emerson
Nothing, except what flows from the heart, can render even external manners truly pleasing.
Hugh Blair
