Note 37 — Literariana.
Reading edition
“There was disorder in the mind—a disturbance of the intellect, something more than that which he was feigning; but if the question of insanity involve the question whether his mind ceased to be under the mastery of his will, assuredly there was no such aberration.” (Reed’s Lectures.)
Dr. Johnson goes further, declaring that Hamlet “does nothing which he might not have done with the reputation of sanity.”
