But that doesn’t mean it’s irrational. Rationality does not require some type of libertarian free will. I like this quote by Christian theologian Randal Rauser:
“Rather, what reason requires is the ability of an individual effectively to track the relationship between propositions, their logical relationships, and supporting evidence. And there is no inconsistency between believing that such abilities can exist in a deterministic universe.”
And determinism does not imply we are some kind of robots. People confuse determinism with fatalism way too often.
