The purpose of this article is to show the conflict that has to do with epistemic and methodological issues involved in Boyle/Spinoza discussion, which allows to appreciate how it should be reassessed, at least two things, in the growing natural science of the Seventeenth Century: i) the preference of a hypothetical and practical knowledge instead of the mere pretence of an absolute certainty of the scientific knowledge. And ii) the investigation of the nature demands a careful experimentation that stresses the development of some epistemological approaches and different method to those to which most modern philosophers were accustomed to.
