As Ernest Becker observes in The Denial of Death, the very thought of disobeying authority appears to awaken the anxiety connected with the possible loss, during infancy, of parental love, respect or support. The unexamined beliefs and experiences that generate our reliance on, and deference to authority, seem rooted in a profound existential uncertainty: the patient looks to the doctor to relieve this uncertainty, not only about not feeling well and not knowing why, but also about not knowing what to do, what action to undertake. In other words, the expertise of the physician relieves the patient of some of the burden of responsibility.
