The ArgumentSociologists of Third World science, who share the dominant assumption in the philosophy of science that the “culture” of specific substantive fields of scientific inquiry is invariant across the globe, have, after a period of blind optimism devoted to building a critical mass of scientists in the developing countries, relapsed into a bleaker mood and see the Third World as a peripheral region lacking in “creativity” in its research programs.Challenging the doctrine of the universality of scientific practice by means (...) of an in situ study of an Indian physics laboratory, an attempt is made to bring to light a particular community's shared ideals of knowledge which animate the everyday practice of its field of study and fashion its choice of problems, style of professional communication, attitudes toward experiment, etc. These local ingredients should not be understood as deficiencies with respect to some arbitrary norm but as what differentiates research practices in different parts of the world.
