There is a continual attempt by the religionists to show that the
brain is other than the expression of the DNA. The DNA constructs a
precisely connected brain and sets the rules for synaptic growth and
strengthening. These rules provide the structure with which the brain
alters itself to adjust to the exterior world. Any statement to the
effect that the DNA does not have sufficient informational capacity to
build such a brain is simply a denial of science.
Any statement that the neurons are randomly connected, or that
behavior is not completely determined by the condition of the neurons
at the instant of the behavior, is a denial of science.
Any reference to free will, or to a soul with causal powers, is a
denial of science. For soul, read spirit, essence, psyche, mind,
consciousness, awareness, intelligence, intellect, mentality, self,
individuality, persona, personality, executive function, conscious
mental field, self-awareness, sentience.
