I’ll answer your earlier/other question later, when I have more time. But this is an easy and fun question to answer…, I think compatiblism is easily explained by considering almost any fictional time travel event. The Star Trek deep space nine episode “trials and tribbleations” is a great example:
Captain Sisko and his team go back in time and witness the events of Captain Kirk and his crew. They Use their historical records to determine all sorts of Details about where Captain Kirk, the Klingons, and the others will be and what they will be doing at any particular time.
Therefore, on the one hand, From Captain Sisko’s Perspective, Captain Kirk’s actions were written in stone, predetermined, and he knew unerringly exactly what Kirk would be doing at certain points (assuming they did not interfere with the timeline.) There was zero possibility that Captain Kirk would deviate, and do something else. His actions were certain, predetermined, set in stone.
at the same time, no one I have ever seen or read who discussed that episode objected on the basis that Captain Kirk had magically been turned into a puppet, his actions being forced, his free will being completely taken away from him… No, instinctively I think we all understand that absolute foreknowledge of an event is completely compatible with free will on the part of the individuals involved.
QED: Captain Sisko’s absolute, unerring foreknowledge of a person’s choice was completely compatible with that individual having genuine free will.
But what about predestination itself, where someone actually chooses or actively determines the course of events? To illustrate this I would go back to the original Star Trek episode. “city on the edge of forever”: very briefly, due to all the time travel science fiction, Captain Kirk had a unique opportunity to choose between two alternate timelines. He had unerring knowledge of which way history would proceed based on the choice he had to make. He essentially had the ability to choose whether the allies won or lost WWII. He chose for the allies to win that war. but is there any way whatsoever that we would think that Kirks ability in that moment to decide which way history would proceed in someway magically took away the free will of Roosevelt, Stalin, or any of the actors or individuals in either the moment or in later history? of course not. Kirk’s knowledge of later events, and his decision for one particular Timeline to proceed rather than an alternate one, had no impact whatsoever on the free will of the individuals involved.
QED: Captain Kirk’s choice of one particular timeline out of two was completely compatible with all the individuals In that timeline having genuine free will.
Now, if we imagine that an infinite, omniscient, and omnipotent creator God who exists outside of time has the ability to shape the timeline of the Universe at every moment, in every situation in much the same kind of way That James Kirk was able to do in that one particular moment… Shaping the timeline, or even choosing one path to proceed among the infinite number of possible, alternate competing timelines… Then it becomes obvious to me that such a God could absolutely predestine and plan whatsoever comes to pass for his purposes, in such a way that does absolutely no violation to the free will and free choices of any individual person.
QED: God’s choice of one particular timeline out of the literal infinity of other “possible worlds” is completely compatible with all the individuals In that timeline having genuine free will.
essentially, compatiblism maintains that something happening can have two entirely separate yet compatible “causes.” Did the allies win WWII because of all the individual free choices that Hitler, Roosevelt, Stalin, Churchhill, and all the other people made? Or because James Kirk chose that outcome over an alternate one? both.
Did Joseph’s brothers betray him because of their freely chosen intent to harm him? or because God chose to send Jospeh into Egypt in order to save their lives from the famine? both. Was it Joseph’s brothers, or God, that sent him into Egypt? both. “It was not you who sent me here, but God.” “You intended to harm me, but God intended it for good.” Was it God, or desert raiders, that took away Job’s livelihood? “The Lord gave, and The Lord took away… shall we accept good from God, and not trouble?” both. both, both, both.
And was Jesus executed because of the free, uncoerced choices of lawless men? or because it was according to the definite plan and foreknowledge of God? both.
both.
Both.
BOTH!
