Psychiatry

One does not need to have an education in diagnosing and curing mental diseases to know that somebody's feeling of having no objective in life can be an important aspect of the mental health of that person.

A person who attempts to cure a patient who experiences his life as meaningless aimless, purposeless, et cetera should at least have the answer to the question "what is the description of the Phenomenon Objective?"

Furthermore it would be helpful for him to know the answer to the question "which role plays an objective in the functioning of the human brain?".
