Eric Husch notes 1) that Edsel B. Grimshaw is a famous critic who blasted V.M. Straka in 1950 for giving S (character) far too much intuition among other things in his article The Cipher's Progress, a review of Ship of Theseus (book).
Grimshaw is also mentioned 2) by Eric Husch as hating a particular scene. The scene is in Chapter 3, when an explosion has just hit the town of B—– near the factory. S. is gazing out at the wharf and sees an alternate space where a boy and girl speak to each other: the boy leaning toward her and the girl leaning away. Grimshaw criticized the scene for being “contemptuous of readerly desire” because it was a digression from the action happening around the explosion.
