Then we have two processes. The deterministic process evaluated the
probabilities and deterministically rejected C.
Then the deterministic process deterministically chose between A and B
by using the output from some other random process.
The deterministic process's use of the random process’s output was
deterministically constrained to A or B.
If it had *become* a random process in the sense I mean - it might
have gone in with the options of (A or B) but then ended up taking
entirely unrelated action X. Or not taken any action at all. Or
turned into a bird.
By random, I’m using the Merriam-Webster definition of: “without
definite aim, direction, rule, or method”.
I don’t mean: “relating to, having, or being elements or events with
definite probability of occurrence”.
As I’ve said before, I think that probabilistic processes still count
Ultimately I think the difference between deterministic and
probabilistic laws is not significant.
If a law is deterministic then under it's influence Event A will
"cause" Result X 100% of the time.
Why does Event A always lead to Result X? Because that's the law.
There is no deeper reason.
If a law is probabilistic, then under it's influence Event B will
"cause" Result Q, R, or S according to some probability distribution.
Let's say that the probability distribution is 1/3 for each outcome.
If Event B leads to Result R, why does it do so? Because that's the
law. There is no deeper reason.
Event A causes Result X 100% of the time.
Event B causes Result R 33.3333% of the time.
Why? For fundamental laws (if such things exist) there is no reason.
That's just the way it is.
Determinism could be seen as merely a special case of
indeterminism...the case where all probabilities are set to either 0%
Yes? Or no?
