Isn't this all about reflective equilibrium?

Define my real values to be the endpoint of the process in which I continually question my intuitions and self-modify until I have a single, coherent set of values and moral intuitions.

Define my used values to be the approximation that I use to make decisions on a day-by-day basis.

Define the discounting hypothesis to be the statement that there exists a utility function that takes a paramater f(p,U) such that:

1. p can be interpreted as the amount of discounting

2. f(0,U) closely approximates our real values.

3. f(x,U) for some x>0 closely approximates our used values.

Then perhaps Eliezer is arguing for the discount hypothesis.
