Science in Christian Perspective
IS MAN ONLY A COMPLEX MACHINE?

Man is a complex machine. His sense detection system is the model and envy of
many attempts to reproduce it in simpler machine form Machine-like functions of
man can be described in terms of the various scientific disciplines. If a man
doesn't know that he is a machine, he's in trouble. If he thinks that he is an
immortal and immaterial spirit who is temporarily living in and
operating a finite
and material body, he doesn't appreciate the Biblical teaching of the body-soul
unity and the wholeness of man created in the image of God.
It's the "only" in the question, "Is man only a
complex machine?"
that causes the trouble. Every "only" is a subjective
judgment of men.
Science knows no "only's." That man is a complex machine is
a scientific
conclusion. That man is only a complex machine is a subjective
philosophical speculation
not derivable from science. It is simply another repetition of the old fallacy:
if science shows us that man is a complex machine, and if we can know nothing
except what science tells us, then man is only a complex machine.
We should expect that every event in which a human being takes part
can be described
on each of the levels appropriately associated with the physical sciences, the
biological sciences, the psychological and social sciences, and ultimately in
terms of that theology which relates the event and the man to Cod. It is never
a question of something happening on this level but not on another;
it is always
a question of something happening on every level simultaneously.
We may expect, therefore, to he able to produce a physical description of every
activity of a human being. Although we cannot in fact produce an
exhaustive physical
description at the present time, there is in principle no reason to
believe that
something on the physical lead must of necessity elude us in setting
forth a physical
description. It is not, for example, necessary for the perspective of
the Christian
faith that Cod be invoked to supply the physical rncchanismn at some
point where
human understanding of the natural physical mechanisms breaks down. Even if a
complete and exhaustive description on the physical level were at
hand, it would
be a false interpretation to conclude that no other description was
valid or necessary
for a complete understanding. It is at this point that the common
fallacy enters;
it is at this point that the true statement, "Man isacomplex
machine,"
becomes the false statement, "Man is only a complex machine."
Consider the most important event in the life of a Christian.
Christian conversion
is not only a physical event, not only a biological event, not only a
psychological
event, not only a social event, not only a theological event. Which
of these descriptions
could be left out without depleting the total understanding of what
has happened
in conversion? To be sure, the focus of the conversion experience is
the relationship
on the theological level between a man and Cod, but it could be no experience
at all if it did not have its effects on the sub-systems of man, on
his sociology
and psychology, and even his biology and physical processes. It appears clear
that the argument is false that the possibility of exhaustive description on a
single level excludes the meaningfulness, validity, or necessity of
descriptions
on all other levels. Any attempt to understand the human being in terms only of
sub-system descriptions will inevitably lead to an impoverishment of life and
a dehumanization of man.
Man is a complex machine. But to assert that man is only a complex machine is
to equate the whole with the sum of its parts, and to fail to
recognize the necessity
for a multi-level description in order to do full justice to what
kind of creature
man is. Even if it should be possible for us to describe in detail the physical
mechanisms associated with every action, every thought, every impulse of a man,
we would still not have a clue to what it all meant without the
recognition that
the man is a child of God, made by Him for love and communion.
