Emma, Volume I, Chapter IX, scan-backed 1816 John Murray first edition on Wikisource. Emma tells her father that one half of the world cannot understand the pleasures of the other while explaining why his grandchildren enjoy rough play that he himself cannot comprehend; this is Emma Woodhouse’s fictional dialogue, not Austen speaking autobiographically.
