THE END.
The text presents a systematic physiological account of disease, arguing that disorders arise from excess, deficiency, or misdirected action of four sensorium faculties that produce fibrous motions. It classifies illnesses by their proximate causes—irritation, sensation, volition, and association—and arranges orders, genera, and species by resulting effects and bodily location, offering practical guidance for diagnosis and treatment. The author critiques prior nosologies, advocates a natural classification to align related remedies, and uses clinical examples to show how identifying proximate causes clarifies symptoms and directs therapeutic methods.
