Jane Austen began Sense and Sensibility when she was barely 20. It was published 16 years later, in 1811, at her own expense; the only clue to the novel’s authorship was the inscription ’By a lady’. In her introduction to this edition, the best-selling Italian author Elena Ferrante – a notoriously private figure whose true identity remains unknown – suggests that Austen’s anonymity only makes her work more intriguing. Whoever Austen was, writes Ferrante, she was ’an extremely cultured, extremely perceptive lady who was well acquainted with the ways of the landed gentry, who knew the rituals of the London bourgeoisie, who was aware of how unstable the world is – of how everything changes in spite of sense and in the tumult of sensibility’.
