Hall defined her philosophy of nursing on the basis of the patient, “if learning is the chief process he uses, then the chief therapy he needs is teaching” (Hall, 1969). She believed that patients come to the hospital in biological crisis (acute episode of disease) and that medicine does a great job at treating this crisis, but fails to treat the underlying chronic disease. This is where she felt that nursing could make a significant difference. In fact, she felt that taking over this sub-acute care was the way for nursing to legitimize itself into a true profession at a time when nursing was even more disrespected.
