It's perhaps a subtle point, but it seems to me that **any and all**
meaning is strictly dependent on context -- and this is at the center
of the understanding gap between Robin and Tyler in the present
I've appreciated and respected Robin and his writings for well over a
decade now, but I've always been slightly jarred by what appears (to
me) an implicit assumption of objectivity in his models, whereas for
me, all models are understood within the context of the observer, all
observations are relative to some prior and inherently uncertain, with
a background assumption of a consistent, rather than "objective"
At this point, for the record, I should state that I find relativism
and post-modernism annoying, and that's not what I'm about.

What is the difference between a human embryo and a duck embryo, if
not a set of biases?
What is at the root of any intentional action, if not bias?
What is "good", "right", or "moral" without bias?
But of course their point is (or should be) that one should prefer
one's instruments (especially Rationality) to be effectively unbiased.
