Is the History of Science Relevant to the Philosophy of Science?

Philosophers have started to use the history of science to address some of their philosophical concerns. In this paper I point out some aspects of contemporary practice that require further consideration in order to achieve a more fruitful integration of history and philosophy: one, the limitations of using case studies; two, the need to articulate how we should use history as evidence. Specifically, I argue that to make progress in the debate about realism we will have to pay more attention to the role of historical evidence.
