Woolf concludes that it was the Suffrage campaign that was the cause of all this. Men must reassert themselves, and thus have put an emphasis upon themselves in their writing. None of this is present in the works of Keats of Shakespeare, which is why she can read Keats and Shakespeare.
To Woolf, the solution is for authors to write not with merely a man's mind or a woman's mind, but to be "woman-manly or man-womanly." There must be a "marriage of opposites," she says. However, upon reading the text, she doesn't clarify what it is to be one of these. She speaks in vague terms of "the curtains [being] close drawn" and the author "[plucking] the petals from a rose," but I don't know what that is.
Obviously it is more than just writing about yourself (as a man does!). Is it that Woolf truly has no idea what it takes to write a novel with both sides of a brain? Does she only know what it is that's being done wrong, or knows of no true solution, or is it something else?
