The Criticism from Theism
Another common objection explicitly goes beyond science to maintain that there is a spiritual level that accounts for
human capabilities and that is not penetrable by objective means. William A. Dembski, a distinguished philosopher
and mathematician, decries the outlook of such thinkers as Marvin Minsky, Daniel Dennett, Patricia Churchland, and
Ray Kurzweil, whom he calls "contemporary materialists" who "see the motions and modifications of matter as
sufficient to account for human mentality."

Dembski ascribes "predictability [as] materialism's main virtue" and cites "hollowness [as] its main fault." He
goes on to say that "humans have aspirations. We long for freedom, immortality, and the beatific vision. We are
restless until we find our rest in God. The problem for the materialist, however, is that these aspirations cannot be
redeemed in the coin of matter." He concludes that humans cannot be mere machines because of "the strict absence of
extra-material factors from such systems."
I would prefer that we call Dembski's concept of materialism "capability materialism," or better yet "capability
patternism," Capability materialism/ pattern ism is based on the observation that biological neurons and their
interconnections are made up of sustainable patterns of matter and energy. It also holds that their methods can be
described, understood, and modeled with either replicas or functionally equivalent re-creations. I use the word
"capability" because it encompasses all of the rich, subtle, and diverse ways in which humans interact with the world,
not just those narrower skills that one might label as intellectual. Indeed, our ability to understand and respond to
emotions is at least as complex and diverse as our ability to process intellectual issues.
John Searle, for example, acknowledges that human neurons are biological machines. Few serious observers have
postulated capabilities or reactions of human neurons that require Dembski's "extra-material factors." Relying on the
patterns of matter and energy in the human body and brain to explain its behavior and proficiencies need not diminish
our wonderment at its remarkable qualities. Dembski has an outdated understanding of the concept of "machine."
Dembski also writes that "unlike brains, computers are neat and precise....[C]omputers operate deterministically."
This statement and others reveal a view of machines, or entities made up of patterns of matter and energy ("material"
entities), that is limited to the literally simpleminded mechanisms of nineteenth-century automatons. These devices,
with their hundreds and even thousands of parts, were quite predictable and certainly not capable of longings for
freedom and other such endearing qualities of the human entity. The same observations largely hold true for today's
machines, with their billions of parts. But the same cannot necessarily be said for machines with
