Categories, intuitions and Kantian space-time

Adán Sús


Kant states that space and time are a priori conditions of experience, while apparently being committed to the euclidean nature of space and absolute simultaneity. His defense of the a priori character of spatio-temporal notions stems from taking them as pure intuitions, so its newtonian nature would derive from the configuration of what Kant names as intuition. Nevertheless, according to some recent discussions, it is not clear what intuition means for Kant and how space-time is determined from it. In this paper I look into the debate about the origin of the synthesis of pure intuition that, according to Kant, would determine the spatio-temporal structure. I discuss to what extent taking into account the participation of categories in such a synthesis might have an effect on the commitment that, according to the kantian perspective, one should have with respect to the metric being determined a priori. My conclusion is that kantian analysis can incorporate the idea of a spatio-temporal metric that is not given, in the sense of universally and necessarily, a priori.
