Time, time dilation, and the Aristotelian view of time

In particular, that spacetime appears curved could be interpreted as evidence that it really is curved, but it could also be interpreted instead as evidence that some force is affecting our measuring devices (Kosso 1998, pp. 102-3; Rickles 2016, pp. 83-90; Sklar 1992, pp. 53-69). (Edward Feser, Aristotle's Revenge, p. 305)

When one has an a priori system, it can be really astonishing where one can end up. In this particular instance, it is astonishing that Edward Feser thinks it is a plausible interpretation of the special theory of relativity that time dilation does not exist. Rather, in Feser's interpretation, the measurement of time is dilated, but time itself is perfectly fine. Given how everything in the material world including the human body runs on physical and chemical and biological processes that proceed in time, what Feser is advocating for here is a split between the clock and processes in time. But since the clock keeps time through mechanical or other processes (e.g. computer chip), how is that supposed to work out?

Feser's proposed interpretation is therefore unscientific. It fails to notice how the human body itself depends on the flow of time to function. The moving of muscles, the transmission of nerve signals — all of these depend on physiological processes that are similar to how clocks keep time. It is simply inconceivable that something that affects "our measuring devices" will not affect us also. If something affects "our measuring devices," then it will affect our perception and engagement with time as well. Electrical impulses will travel slower if time is slowed and so on, and one does not have to be a materialist to hold that to be true.

It is hoped that philosophers actually understand science if they want to propose interpretations of that science. Otherwise, they will appear foolish, as Feser does in this statement of his.
