One last gasp on Intelligent Design.
I spent
two rather lengthy
posts attacking the Popper definition of science, as it applied to the intelligent design theory.
On my way to work this evening, I realized that Intelligent Design is falsifiable, and due to the construction of the theory, it would be relatively easy to do so.
The theory boils down to this: there are biochemical systems in the body which are irreducibly complex, that is to say that the removal of any one piece renders the entire system inoperable. These systems cannot have evolved through neo-Darwinian natural selection, since any small change would result in a non-functioning system. Therefore, the systems must have been designed.
First, as I stated before, that conclusion is flawed, since it presupposes that no other explanation exists to explain irreducible complexity. Ironically, this weakness in the theory is what renders it falsifiable, making it, according to Popper anyway, scientific.
In order to falsify intelligent design, one of two things needs to be done.
- Identify a sequence of steps whereby an "irredicibly complex" biochemical system could arise by gradual stages. For example, demonstrate a biochemical evolution of sight, from the most primitive photosensitive biochemistries to the most complex. The beauty of this approach is that you wouldn't have to prove that the evolutionary chain you construct is in fact the actual process. Merely by providing a viable alternative to intelligent design, you invalidate the theory.
- Discover a new mechanism for evolution at the biochemical level which allows for systems to become irreducibly complex by stages.
Both of these approaches are well within current capabilities, which makes ID falsifiable, and therefore scientific. At least, if you still follow Popper's definition.
