Unity of Science and Ethics of Belief

In this paper, I develop van Fraassen's views about empiricism, science, and the empirical stance to make sense of the unity of the sciences. My claim will be that sciences are unified neither by their products nor by their objects, but rather by scientists' attitudes towards knowledge. In particular, these attitudes take the form of an ethics of beliefs, namely a set of norms that constrain the ways knowledge is conceived and gathered.
