I think it's a very interesting thought to consider the fact that planetary rotation and the movement of objects in space are so definitive, to the point we can create calendars, clocks, etc. based off their movements, yet we consider our actions as humans to be choices. If we weren't sentient, would we even notice? If you actually look at it as if there is an defined path for every single action and choice doesn't exist beyond our perception, does that mean our creation of the illusion of choice was also predetermined? It's a very interesting philosophical pairing with math and math history.
