The Life and Opinions of Tristram Shandy, Gentleman Book 4, Chapter 8 Summary
Something, Mr. Shandy says, keeps the fragile body and mind together. That power allows us to counterbalance evil (paging Batman).
If everything had been hunky-dory with Tristram's birth, George or Edward would have been perfect names. But only the name Trismegistus will counter the evil of a squashed nose. Nice logic, Mr. Shandy.
