I am still trying to find a way to articulate this idea; one which I believe I have expressed to you before in another thread many moons ago, tonyrey.
It relates to the Aristotelian notion of final causes, especially as pertains to biology. To make the unguided development of life sound credible, it is often discussed in such a way as focuses on specific organs independent of the rest of the body. The eye, again, is typically the most commonly used example in this debate of design vs. chance.
The materialist will point out lower organisms such as worms whose “eyes” are nothing more than simple light sensitive cells and then suggest that the eye just gradually, by random mutation, accrued enough mutations to develop to the level of complexity possessed by a human being. This ignores the incredible interdependence of different tissues, nerves, muscles, etc. that must be developed simultaneously, all the way down to the as yet inexplicable faculty that allows these “light sensitive” cells to create the subjective sense of “vision.”
Progressive random mutations in a single organ, such as the eyeball alone, are improbable enough without adding the multifarious interdependent systems that would have to be manipulated by this “unconscious force” in perfect unison to create a functional system.
The same holds true for the rest of the body. If life is an unconscious, unguided process it seems entirely impossible that such a thing could effectively form such an incredibly interconnected and interdependent variety of tissues, fluids, bones, etc. I heard it said somewhere that there are some ideas that are so stupid, you have to be incredibly intelligent to believe them.
I suggest the notion that an accidental product of blind forces could be capable of so nimbly controlling and programming its own development is beyond unlikely, approaching the realm of ludicrous. Considering the probable infinitude of possible mutations, and the fact that most of them would be disastrous, it seems far more likely that life would have mutated itself into uselessness, and therefore extinction, before it even got off the ground.
There is more I wish to express to this effect, but my limited education and attention span prevent me from doing so at the moment. I shall ponder it further and add more should another burst of inspiration strike me.
