Abstract

We propose a view of consciousness as a sort of metaphoric “funnel” transforming a fraction of the parallel processes taking place continually in our central nervous system into something intrinsically serial and sequential. A conscious state is the result of this temporary serialization of a set of parallel mental processes. Before this event, everything is parallel, but also after it, everything returns parallel. As a consequence, the simile we propose is that of a “clepsydra” or sandglass. A conscious state coincides with its bottleneck. Here, we explore possible consequences of the adoption of this model.
