Applying Jackson’s CA to time.  An assumption for simplicity’s sake: the present is the only feature constitutive of folk time.  (We’re analyzing the folk concept of “the present.”)

This works great with Lorentzian relativity, Kon’s first example.  We can keep the concept of “the present.”  In relativity this concept gets eliminated.  Looks like the right result!

But the problem with Jackson’s JCA: we can’t just read metaphysics off a scientific theory the way Jackson assumes.

In an improved account of CA, we should look for three desiderata:

1. Don’t problematically read scientific concepts off a theory

2. Apply to more than one scientific theory

3. Include an analysis of folk time rather than just eliminating the concept
