Abstract

This article discuss two different approaches used to think historical a priori . On the one hand, when Husserl speaks about historical a priori , he refers to the tradition – one way of stating that history of thought is continuous and follows a common spirit. It implies, at the same time, that the tradition, despite being a discourse that precedes the subject, clearly to exist depends on a discursive subject at his present activity. On other, in Foucault’s proposal, historical a priori will be saw from what would make possible the appearance of multiple statements in a given era . Therefore, it is all about a history not guided by subjectivity, but by the discourse itself. What remains of these two conceptions is to know the status of mathematics and physical sciences: they would be a model or an exception?
