The sensible meaning of the Kantian category of possibility

In this article I defend the thesis according to which the Kantian category of possibility only receives a sensible meaning through reference to objects given in time and space. Likewise, I indicate that the sensible meaning that the category of possibility receives in the framework of the Schematism is compatible with the possibility of spatial and temporal objects that Kant presents in the «First postulate of empirical thought in general». Thus, I present some reasons that allow us to understand that although the scheme of possibility is formulated in temporal terms, it presupposes spatial intuitions.
