Query: Present time   The idea of a moving present or `now' seems to form part of our most basic
beliefs about reality. Such a present, however, is not reflected in any of our
theories of the physical world. I show in this article that presentism, the
doctrine that only what is present exists, is in conflict with modern
relativistic cosmology and recent advances in neurosciences. I argue for a
tenseless view of time, where what we call `the present' is just an emergent
secondary quality arising from the interaction of perceiving self-conscious
individuals with their environment. I maintain that there is no flow of time,
but just an ordered system of events.
