Dave Harris says the following in "Knightian uncertainty versus Black Swan event":
In Bayesian thinking, chance doesn't really exist. What does exist is a system that is too complicated and complex to know enough to make statements that you can be sure are 100% true.
That seems to imply the universe / world (or at least the processes that are being modeled) is deterministic for a Bayesian. Is that a universally or at least widely accepted viewpoint?
