wmccomninel now says:
You are making analogies where I think that analogies are not
adequate or appropriate, they are like red herrings which divert our
attention and inquiry. You appeal to exceedingly large scale complex
phenomena to explain exceedingly small scale complex phenomena.
LeRoy: Actually, with respect to your last sentence here, that is EXACTLY what the intelligent design advocates are doing. Presumably their intelligent designer is some 'large-scale complex phenomena', unless you are prepared to make that argument that God is small and simple (and simple-minded?). Nor do they ever bother to grapple with the question of where their putative designer originated. (Who designed God?) Such questions, one senses, would perhaps be regarded as bordering on blasphemy. It rapidly becomes a matter of 'it's turtles, all the way down!'
wmccomninel continues:
There may be similarities which the two share but just as well the
principles of organization at work could be scale dependent and not
similar at all. I simply do not claim to know what those principles of
organization are. I only think, without possessing the ability to
prove, that they must be present to make living cells behave as they do.
LeRoy: Well, we understand that one of the major principles of organization of living cells is nothing more than Darwinian natural selection. After all, non-functioning cells would not be able to reproduce. Are there other 'principles of organization' at work in living cells that we have not yet discovered? Perhaps, but if so, you have certainly not suggested any. Are you prepared to do so?
wmccomninel continues:
Further when I think that the complexity seen in the function of a
living cell requires that some principle of order be invoked I do not
give that principle an anthropomorphic character. It could be the
result of purely physical laws interacting in ways which result in the
observed complexity. Those laws may be all known already but their
interactions too complex to model or there may be effects not yet
discovered as often happens in science and engineering.
LeRoy: If the complexity of a living cell is due to "purely physical laws interacting in ways which result in the observed complexity", then your argument is a universe removed from the arguments that intelligent design thinkers make. In fact, I daresay that very few biologists would disagree with this characterization of living cells. In contrast, the I.D. 'theorists' are specifically invoking a conscious and intelligent entity to 'explain' the complexity of life, not 'purely physical laws'. Moreover, in the past few decades we have come to understand an enormous amount about the interactions that occur in living cells, in terms of those physical (and chemical) laws. Are there things we still don't understand? Sure. But that is hardly a reason for invoking a supernatural intelligent designer. To do so is to fall into the same trap as the ancients who needed gods to explain the lightning bolts in the sky that they did not understand.
wmccomninel continues:
I do not understand the physical laws at nano-scale but there are
unusual effects which are predictable enough to be exploited in the
manufacture of solid state electronics and electro-optics. A living
cell is not a solid state system and could possess processes which are
both dynamic and ephemeral (exceedingly fast and short lived in
duration) which exist only at those exceedingly small scales.
Description and modeling of such interactions and the principles of
organization which they collectively exhibit is beyond the present
ability of science to fully address.
LeRoy: Yes, since I worked in the integrated circuits industry for many years, I know a great deal about the 'effects which are predictable enough to be exploited in the manufacture of solid state electronics'. We are nearly at the same point in our understanding of biological systems, at least at the cellular level. Craig Venter, the man behind the human genome project, believes we are at the beginning of an era of biological manufacturing, in which we will be synthesizing new life forms from basic biological building blocks. Therefore your last sentence here is highly questionable, to say the least.
wmccomninel concludes:
It used to be said that hitting a bullet with a bullet is
impossible. Now it is used in missile interceptors. This analogy like
yours is not appropriate to describing the function of cells but it is
helpful as a reminder that even a simple system which defied scientific
solutions may yield over time. But only if the possibility is not
off-handedly dismissed as being impossible. Or nutty.
LeRoy: Natural selection is not an 'analogy'. It is an empirical fact of the world, repeatedly demonstrated in both laboratory experiments and in the field. The analogy I was drawing was between natural selection and the price mechanism that results from the 'invisible hand' of the market. Some people deny the existence of that, as well. The analogy was deliberately chosen to demonstrate that the primary claim of intelligent design thinkers, that the mere fact of complexity implies a designer, is philosophical rubbish. You certainly haven't convinced anyone otherwise.
