Abstract
What is the exact relationship between analytic philosophy and philosophy of science? In this paper, I will address this question from the perspective of research traditions, with the help of recent histor- ical studies on analytic philosophy. The two groups are particularly focused: the Polish philosophers and the logical empiricists in Berlin. Neither of them is unknown to us. However, by taking seriously their connection to the development of analytic philosophy and philosophy of science as research traditions, I believe, the understanding of our own tradition may be improved.
