This paper is a revalidation of Oliver Sacks's role in the development of medicine's narrative turn and, as such, a reinterpretation of the history of narrative in medicine. It suggests that, from the late 1960s, Sacks pioneered in his 'Romantic Science' a new medical mode that reunited the seemingly incommensurable art and science of medicine while also offering a way for medical humanities to shape clinical reasoning more effectively.
