[Serious] Is the Past Real?

[Angrboda]

I have to wonder if you can have a theory of causality consistent with denial of the past.  I don't think it's necessarily the case that causality as a concept has to survive, but if it's a fiction, it would be one of the more difficult fictions to give up.

In your opinion, is it any more problematic than an eteranalist causality?

I don't really have an opinion. I must confess that I feel a bit out of my depth here.
