Abstract

The theories accounting for cognition based on formal schemata often claim that there is a logic in the human mind. From the thesis on the river given by Heraclitus of Ephesus, in this paper, it is argued that, if that logic exists, it cannot be simple, and that, at a minimum, it requires the assumption of some kind of temporal elements, which, in general, seem not to be considered in such theories. In particular, some reflections about possible ways those elements could be taken into account are presented.
