Metaphor-foods compared to cleaning objects
As Will is slowly introduced to the methods used in the Sanatorium, an overly eager Doctor Kellogg tells him about the foods they use for cleansing the digestive system. First he mentions psyllium seeds, comparing them to janitors cleaning his digestive system with tiny scrub brushes, and then there is hijiki which is compared to brooms that will sweep him clean. This obsession with cleanliness and sanitation is present throughout the time with the character of Doctor Kellogg.
Metaphor-George a walking curse
George comes back into Doctor Kellogg’s perfect white world, and stains it with his presence and demand for money. It pushes Doctor Kellogg back into the past and the years he tried to educate the boy to go on the right path. Ever since George enters the scene, the mood around Doctor Kellogg changes, he becomes less motivated and more irritable. He calls George a walking curse, a curse he is doomed to live with.
A tower of righteous strength and indignation
Right from the start, it is clear that Doctor Kellogg is a self-righteous narcissist spewing unfounded nonsense to his easily-manipulated patients. He answers every question about health with the most grim prognosis unless the patient follows his advice. After Miss Muntz asks him about the usage of tobacco among the young women, he puts on a show of furious contempt, becomes a tower of righteous strength and indignation and pronounces that tobacco destroys the sex glands.
Shepherd to his flock
The first scene that introduces the spectacle of Doctor Kellogg implies the gravity of cult-like manipulation he imposes upon his patients. He makes a show showing stakes and destructive bacteria in them, calling forth the most attractive woman from the audience to promote further manipulation of the male patients and scares his audience to compliance, like a shepherd to his flock, his patients nothing more but sheep who follow his greatness.
