From Andrew Jones at ENST:
One of the most fundamental and useful ideas that has come out of the intelligent design movement is the insight expressed by Bill Dembski as the Law of Conservation of Information. Put simply, the idea is that information does not appear out of nowhere, but can always be traced to a prior source, analogous to conservation of energy or momentum in physics. It has been used to argue that evolution cannot create information, and I think that is true, so long as you properly understand what we are saying. But a lot of critics have not understood it yet.
It has been critiqued from a number of directions; a suspiciously large number of directions in fact: usually if an idea is wrong there is just one main thing wrong with it, so I am always suspicious when any idea is portrayed as “wrong in every way” or gets attacked in a scattergun way. You should be suspicious, too. More.
Of course the LCI is correct. Otherwise, Boltzmann brains or flowered teacups would be appearing everywhere.
And of course Darwinism isn’t even possible. It is amazing the number of tenures today that depend on proclaiming the opposite. If that does not make you suspicious…
