Answer:
Freud would argue that harlan has a psychosis.
Step-by-step explanation:
Psychosis is a term used to identify psychiatric disorders in which a person loses touch with reality. The mental functioning of a psychotic person is compromised on many levels, causing signs and symptoms that include hallucinations, delusions, mental confusion, memory loss, unusual behaviors, among others.
Losing contact with reality means that one does not correctly evaluate one's perceptions and thoughts, which leads one to draw incorrect conclusions about the real world, even if the evidence proves otherwise. This is what is happening to Harlan.
