Why I Am a Presentist

Both geologists and historians study the past, but they have divergent views of the present. Geologists are unambiguously presentist. They believe that the observable present is a crucial resource in understanding the past, because in the observable present we can see and study the processes that have occurred in the unobservable past. For geologists, it is largely uncontroversial that the past not only can but should be interpreted with reference to the present.
