In the age of decolonization, Indian psychology engaged with and nationalized itself within global networks of ideas. While psychology was eventually applied by public intellectuals in explicitly political arenas, this essay focuses on the initial mobilization of the discipline's early Indian experts, led by the founder of the Indian Psychological Association, Narendranath Sengupta. Although modern critics have harshly judged early Indian psychologists for blind appropriation of European concepts, an analysis of the networks through which the science of psychology was developed challenges this oversimplification. Early Indian psychologists developed their discipline within a simultaneously transnational and nationalistic context, in which European ideas overlapped with ancient texts, creating a deliberately “Indian” brand of psychology. As the discipline of psychology exploded across the world, Indian psychologists developed a science of swaraj, enabling synergies between modern psychological doctrine, philosophy and ancient texts. This paper explores the networks of ideas within which modern Indian psychology was developed, the institutional and civil environment in which it matured, and the framework through which it engaged with and attempted to claim credence within transnational scientific networks.
