- How do you feel about substituting the term epiphenomenon? This is more
- concise in that it means that the property in question is caused by the
- primary phenomenon, although it is not necessary that the cause/effect
- relationship be one that is intuitive, predictable, or reducible.
-
- This idea of K's that all destinations must somehow be reducible to
- a roadmap that details how you got there is jejune.
-
- In the simplest of examples:
-
- A cake that exists now is not reducible to a recipe of how to make the
- cake. That information is not inherent in the cake itself. What can
- be done is to deduce a way to reproduce the cake, creating a new
- recipe. But there is no way of ever deducing the original recipe with
- absolute certainty. That information is gone.
-
- However, if every time you have angel food cake, it brings back
- certain memories of your grandmother, those memories are an epiphenomenon
- of the conjunction of angel food cake and you.
-
- Of course, K will notice that despite the fact that the recipe is unknown,
- we will infer that the cake had a creator. This is the classic "looks
- designed" arguement, and is what the shishya is prattling on about in his
- "who is the programmer" arguements.
-
- So a slightly more exotic example:
-
- In Africa something profound and amazing was discovered: an ancient
- nuclear reactor! This was a sustained and periodic nuclear fission reaction.
- The exact recipe of how that reactor came to be there and how it was put
- together we will never know. All we have is the finished product. However,
- there is one thing that we do know: that although this is a highly complex
- and full of information effect (I think even K will admit that the
- information content of the necessary components and requirements of
- a sustained fusion reaction are orders of magnitude higher than the
- components and requirements for a cake), there was no intelligence or
- creator that designed and implemented it, because it has been in the
- ground for many thousands of years before any intelligent life walked
- the earth! Only the random forces of nature managed to accomplish what
- took mankind many years of concerted effort.
-
- Where did the information come from? The property of the nuclear reactor
- was an epiphenomenon of the natural forces that brought the constituents
- together in that place and time.
-
- The K believes that epiphenomenon cannot exist. That all information
- flows downhill. It can degrade, but never increase. And that since
- our original laws are simple, that complexity cannot arise. He doesn't
- realize that the epiphenomena are not deducible from the simple laws.
- But they are all there, hidden from view until we delibrately, or nature
- blindly, brings out the wealth of information implicit within.
-
- We have seen it happen time and again. Abiogenesis is simply an
- inference from many similar observances throughout all of nature.
