The brain is a physical component which must be determined by the genetic
code of the individual. Isn't that what cloning is all about? What I said in
the letter is that human thought (conceptual thought) cannot now, and never
will, be explained in terms of brain action--the brain is a necessary, but
not sufficient, condition of conceptual thought. That will remain a mystery.

I am attempting to contrast extreme materialism to the theistic worldview.
In the genre of dogs there is a bell shape spectrum of what a dog is. By
selective breeding, I am sure you can get all sorts of dogs with all sorts
of looks, kindliness, ferocity, disposition, etc. Of course, the sin nature
cannot be varied since there is none in animals.

I am arguing by showing how ridiculous the purely scientific view of man is.
Witness the strong stand of homosexuals on the nature of their sexual
preference--as being something one is born with. [I do not think quantum

My prejudice is that animals are highly sophisticated computers and the
difference between animals and man is one of kind not degree. Therefore, all
the scientific studies on animals will give rise to all sorts of benefits
for man, but the essence of our nature will never be determined by such
studies. One can view the animal as being analogous to our brain, purely
physical, but we are far more than that.
