Is psychoanalysis a science? An answer in light of scientific pluralism

This paper explores the longstanding debate on whether psychoanalysis qualifies as a science. Grounded in the Brazilian context, where recent publications have revived the debate, I examine the demarcation problem in the philosophy of science, highlighting how traditional criteria for defining scientific knowledge may exclude epistemically fruitful practices, such as psychoanalysis. Drawing on the perspectives of scientific pluralism, I argue for a more inclusive understanding of science, where diverse methods and epistemological approaches are recognized as legitimate contributions to addressing complex phenomena such as mental health. Ultimately, the rigid application of demarcation criteria can obscure the value of psychoanalysis, whereas scientific pluralism offers a pathway for integrating it into broader scientific discourse.
