MONOMANIA
Exaggerated preoccupation with one thing
“As to Claggart, the monomania in the man— if that indeed it were—as involuntarily disclosed by starts in the manifestations detailed, yet in general covered over by his self-contained and rational demeanor; this, like a subterranean fire, was eating its way deeper and deeper in him. Something decisive must come of it.”
-Herman Melville
