Norman Podhoretz writes his history

"The first half of the book, which tells the story of “how the Jews became liberals,” is narrated in “the impersonal voice of a historian — an amateur, to be sure, but one who has relied on a variety of professional authorities for help and guidance.” These chapters are mainly anthologies of congenial quotations. There is something a little risible about the solemnity with which Podhoretz presents encyclopedia articles as evidence of his erudition (“I relied most heavily on one of the great works of 20th-century Jewish scholarship, the Encyclopaedia Judaica”); there is even a reference, slightly embarrassed, to Wikipedia. From his footnotes you would think that the most significant Jewish historian of our time is Paul Johnson. And there is a decidedly insular reliance upon the pages of Commentary, the magazine he edited for 35 years. His parochialism can be startling: Samuel ha-Nagid, the astounding poet, warrior, statesman and scholar in Granada in the 11th century, reminds him of Henry Kissinger! Podhoretz seems to be living the Vilna Gaon’s adage — maybe he can find it in some encyclopedia — that the best way for a man to preserve his purity is never to leave his house."
