A focus on the fact that neither space nor time are fundamental entities in many popular approaches to quantum gravity is also taken up by Susan Schneider (2018). There is a certain plausibility to the thesis that conscious experience is essentially temporal, which would seem to imply that consciousness cannot exist at the fundamental level of reality if time does not exist at the fundamental reality. Barry Dainton (forthcoming) also critiques panpsychism starting from the assumption that consciousness is essentially temporal, but this time focusing on the fact that for photons, as entities that travel at the speed of light, time does not pass. Einstein famously asked what it’d be like to ride on a beam of light; Dainton wonders what the panpsychist should think about what it’s like to be an electron.
