Science policy depends crucially on what we mean and understand by science. Science and Technology Studies (STS) today is a much professionalised discipline drawing upon other fields such as history of science, philosophy of science and sociology of science. STS offers a deeper understanding of the nature of science and technology, its relation to society and politics, the uniqueness of its social processes and so on. All of this matters deeply to science policy. In this talk, he will be discussing the insights we can take from a philosophy of science approach to the nature of science and the implications of it for science policy, especially for a country like ours.
