Women could start writing by earning money... 
"Aphra Behn proved that money could be made by writing at the sacrifice, perhaps, of certain agreeable qualities; and so by degrees writing became not merely a sign of folly and a distracted mind, but was of practical importance."

The language of men and women:
"Charlotte Brontë, with all her splendid gift for prose, stumbled and fell with that clumsy weapon in her hands. George Eliot committed atrocities with it that beggar description. Jane Austen looked at it and laughed at it and devised a perfectly natural, shapely sentence proper for her own use and never departed from it. Thus, with less genius for writing than Charlotte Brontë, she got infinitely more said."
