I've read many of Philip Roth's novels, and have many more still to go. He can be a challenging read, sometimes deceptively simple, sometimes confounding, almost always thought-provoking and worthwhile. If you haven't read The Plot Against America, I recommend it highly.
To me Roth is best remembered as the author who taught me about the bright line between fiction and autobiography, and that readers would do well to stop conflating the two (although they never will). Critics and readers were obsessed with this question, and seemingly could not see Roth's novels through any other lens. The Guardian quotes him:
I write fiction, and I’m told it’s autobiography. I write autobiography and I’m told it’s fiction, so since I’m so dim and they’re so smart, let them decide.Roth grew so tired of responding to questions and accusations about which bits of his work were autobiographical and which were fiction, that he declared a moratorium on the subject. He wrote more than one novel that purposely obfuscated the distinction in weird twists worth of M.C. Escher. The narrator of Operation Shylock, for example, is a character named Philip Roth, who is being impersonated by another character, who stole Roth’s identity.
I haven't read any of Roth's work for a long time, and his death reminds me to keep his last body of work on my list: Everyman (2006), Exit Ghost (2007), Indignation (2008), The Humbling (2009), and Nemesis (2010).
