In accordance with Kraepelin's predictions of a good prognosis, Warburg resumed studying art while he was still staying in Binswanger's clinic. Convinced of his own recovery, he proposed holding an academic lecture in the clinic titled "Images from the Region of the Pueblo Indians of North America," which took place on April 21, 1923. With this renowned presentation ("Lecture on the Serpent Ritual"), Warburg intended to demonstrate that he could resume a normal life as an art scholar despite the mental illness that kept him away from his library for 6 years. In a letter to his brother 1 year later, Warburg claimed to feel "a mounting internal driving force" leading to a final healing. Eventually, he was discharged from Belle Vue in August 1924. Given the conflicting diagnostic hypotheses on Warburg's mental illness, it remains unclear how much Warburg's recovery and art scholarship could have benefited from current psychopharmacological interventions.
