Schopenhauer argued that the will — the blind, striving force underlying all life — operates prior to intellect, not the other way around. The body, in his framework, is not a vessel the mind inhabits but the will made visible: desire crystallized into flesh, bone, and organ. This is a strange idea until you sit with what it implies for medicine. When a patient refuses a treatment that is unambiguously in their interest, or pursues one that clearly isn't, the clinical reflex is to diagnose a reasoning error — poor health literacy, anxiety, denial. Schopenhauer would push back: perhaps what you are encountering is not a failure of understanding but a disclosure of will, something deeper than cognition that expresses itself through the body before the patient can articulate it in words. The practical consequence is subtle but real. Interventions aimed at correcting a patient's beliefs may be aimed at the wrong level entirely. What the body is doing — refusing, persisting, returning — may be communicating something that comprehension-checking cannot reach.

Think of a case where a patient's behavior and their stated understanding were in direct conflict — what were you actually treating?
