I am jotting down some rough thoughts on how eternity depends on mortality.

Being an agent means making meaningful choices.

Choices are meaningful if they have consequences.

Consequences need an environment of constraint or limitation. Without opportunity cost, choices are not meaningful.

If eternity is timeless and all encompassing, there are no meaningful choices.

If eternity is timeless, choice is still possible. But there is only one choice to make, like the Catholic idea of what angels decide. This is because there is no time to make other choices in. Paradoxically, removing the limit of time puts a limit on choice.

If eternity is endless time, then there are plenty of choices to make. There may not be meaningful choices though. In endless time, anything can and will happen. So there really are no consequences. If you take the low road, and I take the high road, we still both get to Scotland. How long doesnt matter, just like the prices of things don’t matter if you have infinite cash.

So eternity can only be meaningful in connection to mortality.
