Abstract
The aim of this paper is to expose a philosophical analysis of the type and development of a disease that, over time, became a capital sentimental experience in Late modernity: nostalgia. While the Ancient World concentrated on the study and diagnosis of a close disease like melancholy, nostalgia burst into medical manuals as a hybrid pathology between moral error and bodily defect. Its gradual assimilation rooted in a specific experience of temporality with important epistemological, political and existential connotations. throughout this study we set out some fundamental milestones in the establishment of the conditions of possibility of this sentimental experience and we draw some connections with classic references that preluded its diagnosis and the therapy. nostalgia not only has been acquiring a specific centrality in the contemporary world, but it has also been highlighted as a central experience in philosophical literature.
