DNA does not code for locks and keys to govern protein assembly. The
folding of protein remains a mystery, as any biochemist can tell you.

Says who? Did you read the quotes from Endy/Yin and Gilman? Biological
processes do not necessarily react predictably to given stimuli. You're
still dealing with the body as if it were an automobile engine. As Kant
pointed out, in a machine the parts are built so as to fit each other. In
an organism, the parts build each other as they build themselves. Thus all
the parts identify with each other holistically. Organisms exhibit
"self-organization" (Kant's term). There's no "self" in a machine.
Mechanistic biology is incompatible with the holistic notion of self-nature.
Perhaps you weren't aware of that.

When electromagnetic fields were first discovered, it was claimed that these
were "vague and mystical." The belief in the necessity of physical
contiguity is the basis of the concept of the ether. The universe does not
function according to contact mechanics. Mechanistic theory long-ago
accepted the reality of fields and resonance. There's no reason why these
phenomena can't be applied to biology.

You are really an ass. Obviously I'm not claiming that the universe is a
recursive hallucination. It's been my experience that paying attention is
useful in these situations.
