The objective of this work is to present the relationship between History of Science -more specifically, History of Physics- and History of Philosophy. To do this we are going to see the relevance of the Einstein´s Physics on Philosophy as Epistemology of Sciences, and for Sciences. This relevance is linked with the change in the understanding of the knowledge that Einstein made. To view an overview of the context of this change -that is a tension between Kantian Epistemology and Epistemology implied in Einstein Physics- I will review how Kant to set as epistemological paradigm. This objective consist of a global review of the earlier philosophical tradition.
