My impression is yes. Without simplifying assumptions like using cognition to

understand and manipulate reality (ie. cognition as being equivalent to

approximating so intractable Bayesian calculation), explicit Bayesian

calculations will be far too expensive.

The programming tricks necessary involve creating a mind.

The use of Bayesian probability is it's a model of truth and rationality. One

that seems to cover everything (see Jaynes for starters). As such, any mind

that actually seeks truth is in fact approximating some Bayesian calculation.

I believe you can get stronger statements even that this. It does not mean

you explicitly calculate Bayes theorem, or run through the mathmatical

calculations statisticians typically use, or anything that looks like maths

at all. It's more of a framework.
