Epistemological issues in the history of Italian psychiatry: the contribution of Gaetano Perusini (1879–1915)

In the late nineteenth and early twentieth centuries, Italian psychiatry was characterized by its emphasis on an organic explanation of mental illness. ‘Cerebral mythology’ was a major influence in Italy, at least until the second half of the twentieth century, often at the expense of the development of psychology. In this context, a few psychiatrists adopted a different epistemological perspective, based on a more ‘integrative’ view of their discipline. In particular, Gaetano Perusini stands out. He promoted the concept of psychiatry as a science which embraced many different fields, thus emphasizing the theme of pluralism, which is still debated today in the philosophy of science and psychiatric practice.
