Once Present, Now Past – David Sanson (Illinois State)
Those of us who think that some of the fundamental facts that constitute reality are temporary, and so subject to change, must account for a corresponding contrast between past and present. That contrast cannot be captured by pointing to the facts that constitute reality; it requires us to point to the facts that once constituted reality too. So, if the fundamental facts are temporary, then the past is explanatorily ineliminable, but it is not real. This gives us a reason to be Presentists rather than Moving Spotlight Theorists or Growing Block Theorists, and it gives us a reason, as Presentists, to reject the demand that truth be grounded in being.
