You're confusing determinism with predictability, but I thought we'd already covered this. — fishfry

According to the page on the subject, determinism and predeterminism are "closely related":

https://en.m.wikipedia.org/wiki/Predeterminism

Predeterminism is the philosophy that all events of history, past, present and future, have been already decided or are already known (by God, fate, or some other force), including human actions.

Predeterminism is closely related to determinism.[1]

The concept of predeterminism is often argued by invoking causal determinism, implying that there is an unbroken chain of prior occurrences stretching back to infinity. In the case of predeterminism, this chain of events has been pre-established, and human actions cannot interfere with the outcomes of this pre-established chain. Predeterminism can be used to mean such pre-established causal determinism, in which case it is categorised as a specific type of determinism.[2][3] It can also be used interchangeably with causal determinism—in the context of its capacity to determine future events.[2][4] Despite this, predeterminism is often considered as independent of causal determinism.[5][6]

If you believe that everything has a reason, it does not mean that you also know that reason. Predictability requires indeed both.

After reading all that i was a little unclear on pre- versus regular old determinism. The text passages are the kind of philosophical writing that always makes my eyes glaze.

Hmmm, determinism doesn't mean that everything has a "reason." If you have some Rube Goldberg machine and you start it, it's perfectly deterministic. But it doesn't have any "reason." It's just one thing causing the next thing.
