In this paper I discuss how feminist research focusing epistemological issues can be used within computer science (CS). I approach and explore epistemological questions in computer science through a number of themes, which I believe are important to the issues of what knowledge is produced as well as how it is produced and how knowledge is perceived in CS. I discuss for example paradigms and metaphors in computer science, the role of abstractions and the concept of naturalisation. In order to illustrate epistemological views in CS and how these can be questioned from the viewpoints of feminist epistemology, I also do a close reading and commenting of a recent book within the philosophy of computing
