From Swift: The Man, His Works, and the Age, Volume 1: Mr. Swift and his Contemporaries, by Irvin Ehrenpreis
EARLY
"Swift's knowing how to read at an early age need not imply that he was unduly precocious. The achievement was apparently a goal not infrequently set by eager parents or guardians. Aubrey reports that Katherine Phillips 'had read the Bible thorough before she was full four years old'."
