To the Editors: I read with interest Michael Chabon’s fine piece “‘Ulysses’ on Trial.” While the story was well told, I was profoundly disappointed by its lionization of Morris Ernst. Mr. Ernst was, unfortunately, far more than a clever lawyer who played crafty legal games on behalf of liberal ideals. In the 1950s, while national counsel of the ACLU, he repeatedly offered his services to the FBI to spy upon potential clients and report on the doings of that organization.
