I don't see how conflating inscrutible with non-deterministic is useful. But this is the argument the author is making. They seem to argue that it is a useful thing to do scientifically. Perhaps philosophers would do well to focus on whether a different person in the same circumstances would be forced to make the same decision. The answer is clearly no. But not because of a lack of determinism.
