The Blind Programmer

 

Patricia Smith Churchland, however, in response to a version of the Argument from Reason presented by Geoffrey Madell, attempts to defend materialism by suggesting that although humans, unlike computers, are not products of intelligent design, the evolutionary process simulates intelligent design in such a way as to provide reason:

There is a fatal tendency to assume that intentionality cannot just be a function of the neurons and their connectivity, but that there must be someone in the head who interprets neuronal signals, who sees the activation patterns of the visual cortex, who takes the data and makes a free decision, and so on. As Dan Dennett has tirelessly pointed out, postulating homunculi does not explain anything - it just defers the question. And on this, even someone as wedded to intrinsic intentionality as Searle, agrees. If AI has taught us anything, it is that effects which seem to require an intelligent homunculus can really be done by stupid elements properly hooked up. Who hooked us up? Evolution.

So, not only do we have a Blind Watchmaker, we have a Blind Programmer.

But stupid elements cannot select in the interests of truth, and can they add up to determinate meanings? Without determinate meanings it is never clear what anyone means by anything, and logic is impossible.
