No woman has to prove herself a woman in the grim way a man has to prove himself a man. He must perform, or the show does not go on. Social convention is irrelevant. A flop is a flop.

-Pagels, Heinz R(udolf)
  Sexual Personae: Art and Decadence from Nefertiti to Emily Dickinson, ch.1,'Sex andViolence, or Nature and Art'.

No good poetry is written in a manner twenty years old, for to write in such a manner shows conclusively that the writer thinksfrombooks, conventionand cliche¤  ; and not from life.

-Pound, Ezra Loomis
  'Prolegomena', in The Poetry Review, Feb.

To the Lords of convention 'twas Claver'se who spoke, 'Ere the King's crown shall fall there are crowns to be broke; So let each Cavalier who loves honour and me, Come follow the bonnet of Bonny Dundee.'

-Scott, Sir Walter
  The Doom of Devorgoil, act 2, sc.2,'Bonny Dundee', stanza1.
