In an encomium to the intellectual legacy of the late Gertrude Himmelfarb, the distinguished historian of British manners and mores who died last month, Daniel Johnson takes her understanding of what she called the “de-moralization of society” as prophetic in its anticipation of the “hollowing-out of Western civilization.” Yet, Johnson writes, Himmelfarb “never succumbed to pessimism.”

On August 9, 2001, Ahlam Tamimi and Izz al-Din Shuheil al-Masri traveled from the West Bank to Jerusalem, where Masri detonated himself in a Sbarro’s pizzeria, killing seven children and eight adults, and injuring scores. When the two passed through an Israeli checkpoint earlier that day, they appeared to be a young couple; had Masri been alone, police almost certainly would have stopped him and discovered the deadly bomb in his guitar case. Tamimi was arrested shortly thereafter and sentenced to life in prison. Ten years later, she was among the 1,027 Palestinian prisoners exchanged for the captured Israeli soldier Gilad Shalit. She now resides in Jordan.
