Yes, that's the point. Thanks for stating it in yet another way.

The word "epiphenomenon" is loaded with expectation/intention. It works quite well in 
artificial systems where we can simply assume it was designed for a purpose. But in 
"natural" systems (like the hyena case), if we use that concept, we've imputed a *model* 
onto the system.

I would go even further (encroaching on Marcus' example) and argue that even if someone 
*else* designed a system, you cannot reverse engineer that designer's intention from the 
system they built. The agnostic approach is to treat every system you did not build 
yourself, with your own hands, as a naturally occurring system. (This is the essence of 
hacking, including benign forms like circuit bending.) I would ... I want to ... but I 
can't take that further step without a preliminary understanding that "wild 
type" systems don't exhibit epiphenomena at all. They can't, by definition. If some 
effect *looks* like an epiphenomenon to you, it's because *you* imputed your model onto 
it. It's a clear cut case of reification.

Not to be argumentative (though it seems hard to have any conversation on this list that doesn't end up feeling like an argument) but Isn't the *point* of hacking to discover ways to use "bugs" of an intentionally designed system *as* "features", often in combination with other bugs/features?   Maybe *I* impute too much into the idea of "hacking"?  (does one impute *into* or *onto* BTW?)

I admit, when I follow clickbait with "hack" in the title sometimes the target of the hack is a system *not* designed/built by humans with intentions which the "hack" is overcoming/circumventing/re-tasking... but I don't think of that as a "hack" as much as "thoughtful understanding".  The vernacular use of "hack" seems overly broad to me.

I suppose the character of Sherlock Holmes is characterized by the overlap of these two abilities (encyclopedic knowledge of human-built and natural systems, along with an acute analytic ability to deduce and infer and and a similar acute ability to synthesize disparate elements of those systems to achieve a specific purpose)?   Though I suppose the latter is more in the domain of the Archetype "McGuyver", leaving Sherlock more to the domain of engineering *humans* to admit to or demonstrate their culpability in something or another.   McGuyver seems to be intent on breaking or remaking things to fulfill his own current desire.

In trying to normalize your terms/conceptions to my own, am I right that you are implying that 
intentionality is required for epiphenomena (reduces to tautology if "unintended" is key 
to "epi")?

This leads us back to the teleological debate I suppose.   The common (vulgar?)  
"evolution" talk is laced with teleological implications...  but I think what 
Glen is saying here that outside the domain of human/sentient will/intentionality (which 
he might also call an illusion), everything simply *is what it is* so anything *we* might 
identify as epiphenomena is simply a natural consequence *we* failed to predict and/or 
which does not fit *our* intention/expectation.

We watch a rock balanced at the edge of a cliff begin to shift after a rain and 
before our very eyes, we see it tumble off the cliff edge and roll/slide/skid 
toward the bottom of the gradient but being humans, with intentions and 
preferences and ideas, *we* notice there is a human made structure (say a 
cabin) at the bottom of the cliff and we begin to take odds on how likely that 
rock is to slip/slide/roll into the cabin.   *we* give that event meaning that 
it does not have outside of our mind/system-of-values.   The rock doesn't care 
that it came to final rest (or not) because the cabin structure in it's (final) 
path was robust enough to absorb/reflect the remaining kinetic energy in the 
rock-system and the cabin doesn't care either!   We (because we are in the 
cabin, because we built the cabin, because we are paying a mortgage to the bank 
on the cabin, because we intend to inhabit the cabin, because we can imagine 
inhabiting the cabin before/during/after the collisions) put
a lot of meaning and import into that rock coming to rest 
against/on-top-of/beyond the cabin, but the rock and the cabin *don't care*.   
If instead of crushing the cabin, the rock grazes it on the side where there 
was a dilapidated porch you intended to demolish, carrying it away and 
crumbling it's bits to compostable splinters in the ravine *below* the cabin 
out of your site, you might want to refer to the epiphenomenal nature of 
rolling stones as clever demolition and removal crews?

I'm probably just muddying the water (at the bottom of the ravine, now filled 
with cabin-deck bits).
