Assuming mechanism, I don't see how we can avoid this.

Well, then it is also the simple explanation of the behavior of  
particles in nature. Something which, in my opinion, confirms the  
statistics on computations which is forced by digital mechanism.

Happy NewYear, Colin,

you just came up shy from the notion that all this is a part of the
anthropocentric maze.
Physicists' hegemnony over (scientific?) thinking is embedded into the
math-maze of numbers and this, too, may be a human invention (according to
D. Bohm). So all the 'stories' and conclusions (including Russell's
'Occamistic simplification') are products of the human mind - not a 'MUST
believe' for the existence we are part of.
All is included in your 'perceived reality' we have access to.
We are handicapped into our human limitations, tacitly we should accept
that.
Of course we cannot step out of our borders, but as a consequence of
thinking 'human' we should be cautious when drawing ALL_generalized
conclusions.
We don't know 'what else' is going on. Even limitedly (distorted?) what we
are concerned with. Everything is more than the everything we can imagine.

"Must" in the sense that it is a "neat" idea, or even a "beautiful"
idea. This will correlate to some notion of simplicity under Occam's
razor.

Then it is probably coupled in this case with giving the right answer.

Of course it is always possible that it will be found wanting tomorrow :).

So we "must", must we?

A mathematical construction by humans, happens to cohere to some extent 
with reality.
A mere description.

A million other descriptions, also constructed by humans, could be as 
predictive of how the universe appears.

What extra belief system must exist in order that someone conclude that 
we 'must' chose a "sum of all histories" as "the" story? Why is the 
universe compelled to be such a thing?

Rhetorical question...don't answer. Just think.

happy new year, everythingers.

cheers
