Here.  (Our earlier take here.)  From the text:

How could someone who knows so little philosophy and is so bad at the philosophy he does know conjure up the arrogance required to make embarrassingly misinformed, sweeping generalizations about it?….I think I found the answer in an old Sam Tanenhaus profile of the pompous fraud:

A prestigious Kellett fellowship took Wieseltier to Oxford in the fall of 1974 to study philosophy, but when he got there ”philosophy at Oxford was in transports of logical notation,” he remembers. ”I had no interest in studying mathematical logic or the logical analysis of language.”

Allow me to translate that: Real philosophy is hard, so rather than even try to do it, Wieseltier spent his fellowship sucking up to Isaiah Berlin and quit grad school a few years later, at a time when it was still possible to become a celebrated public intellectual without having expertise in anything. Over the next thirty some-odd years, having turned enough clever phrases and misappropriated enough philosophical concepts to secure a reputation among easily deceived people as a learned man…Wieseltier came to believe his own delusional self-flattery.

Wow!
