Traditionally, epistemology has dealt with the ways in which an individual acquires knowledge through perception and reasoning. However, in recent years it has become apparent that the traditional discussions of knowledge in general, and scientific knowledge in particular, fail to capture important aspects of the social dimension of knowledge. We acquire most of our beliefs from the testimony of others, including experts, and from social institutions that are in charge of the generation of knowledge. The relatively recent branch of philosophy that deals with the social dimensions of knowledge is called social epistemology. It has developed through dialogue with the history of science, sociology of scientific knowledge, anthropology, and philosophy of science. The course will provide an introduction to social epistemology, in general, and social epistemology of science, in particular. It will deal with various aspects of the nature of knowledge from this new perspective, including issues such as the development of scientific knowledge, 'knowledge that' (something true) vs. 'knowledge how,' the influence of social and cultural factors on scientific methodology, scientific rationality and scientific knowledge, scientific realism vs. social constructivism, distributive cognition, holism vs. methodological individualism, trust, expertise, consensus, distributive epistemic injustice, and feminist epistemology.
