As we move up our space/time-line, what will be has been, what has been remains, now is just now.

An errant thought.

The entitlement to believe what on careful reflection seems to be the case, where there is no reason to doubt it, is the necessary condition for being able to form any justified beliefs at all. ... The only way to pursue the truth is to consider what seems true, after careful reflection of a kind appropriate to the subject matter, in light of all the relevant data, principles, and circumstances.
