We summon the arch-mechanic of our day, the medicine-man.
And a marvelous earnest fraud he is, doing his best.

He is really wonderful as a mechanic of the human system.

But the life within us fails more and more, while we marvelously tinker at the engines.
Doctors are not to blame.
It is obvious that, even considering the human body as a very delicate and complex machine, you cannot keep such a machine running for one day without most exact central control.

Still more is it impossible to consider the automatic evolution of such a machine.

When did any machine, even a single spinning-wheel, automatically evolve itself?
There was a god in the machine before the machine existed.
So there we are with the human body.
