Do you suppose JA writes about the variety of educations not only in P&P, but in other works because of the variety she saw around her? Or gives Elizabeth a stunted education because she herself had an education that was not up to the accomplishments that Caroline Bingley describes in the forced stay at Netherfield. In P&P Elizabeth who may not be as educated as Georgiana Darcy or Caroline Bingley, is certainly a force to behold. Is that JA's tongue and cheek way of giving credit to women in her time that might not have had good educations? Or just drawing attention to the different class expectations of women.
