English professor Frederick Crews has made a career of his war on Sigmund Freud, and one might think The Post’s reviewer of Crews’s book, “Freud: The Making of an Illusion, ” would have been a little suspicious of a biography that is an exercise in animus, invective and marketing [“ Faking science to feed his own ego ,” Book World, Sept. 3].

Freud was no saint or hero — as even science writer Matthew Hutson could tell from taking an “informal poll” on Facebook. Yet Freud continues to haunt popular culture. As curator of the 1998 Library of Congress exhibition “Sigmund Freud: Conflict & Culture,” I saw both the compulsive, mindless criticism and blind allegiance that the founder of psychoanalysis generates. Crews and Hutson might have considered this fascinating dynamic had they not been so happily distracted by momentous questions of extramarital sex and the use of cocaine.
