The
Nature of Science and the "Scientific" Process
"Science in fact has
nothing to do with causality; its aim is the discovery of
similarities." Gordon Clark, Thales to Dewey (Baker
Book House, Reprint 1980), page 380.
The following quotes
are four conclusions in Gordon Clark's book, The Philosophy of
Science and Belief in God, pages 91-95, (Trinity Foundation,
see below). These were numbered by me, not Dr. Clark.
1) "The utmost
effort of human reason is to reduce the principles of
natural phenomena, to a greater simplicity, and to resolve
the many particular effects into a few general causes, by
means of reasoning from analogy, experience, and
observation. But, as to the causes of these general
causes, we should in vain attempt their discovery. nor shall
we ever be able to satisfy ourselves, by any particular
explication of them. These ultimate springs and
principles are totally shut up from human curiosity and
enquiry" (David Hume, Enquiry, Section IV, Part I, in the above
book, p. 92).
2) The bare
assertion that science leaves us in ignorance of the
workings of nature is not a sufficient philosophy of
science. Something must be said of the nature of and
use of science. Therefore, operationalism (see
below) is
offered, not as a general theory of epistemology, but as the
best available philosophy of science.... Only by denying
that science is cognitive can one justify the use of
contradictory theories... (for example, light as both wave
and particle).... No sane person can accept them both
as accurate descriptions of nature. But if science,
instead of being regarded as cognitive, is taken as a method
for dominating and utilizing nature, then there is nothing
reprehensible in using these incompatible formulas.... Can a
formula be false and useful? It can... (for example,
cows with milk fever and germ theories)... Operationalism
will accept the procedures as useful, but the theories of
how nature works ... (may be false). Science then must
not be regarded as cognitive, but rather as an attempt to
utilize nature for our needs and wants.... Instead of being
the sole gateway to all knowledge, science is not a way to
any knowledge.
3) The relationship
between science on the one hand, and religion, morals, and
other normative disciplines on the other must be construed
in terms radically different... Can a scientist believe,
know, or prove that the world existed for more than
twenty-four hours, or even five minutes? ... Much less can
physics demonstrate the non-existence of a Supreme
Intelligence who did what gravitation could not do and who
directs the whole universe for His purposes.
4) Science cannot
determine its own value... By science bombs are made and
cancer may be cured. Most people think that bombs and
medicine are good to have. But, there is no experiment
that proves their goodness.... But can any experimentation
demonstrate that either the destruction of cities (and life)
or the extension of life is good?
More
on Operationalism and Science as Knowledge
The view that science
explains nature has in the recent past been challenged by an
alternate theory. Operationalism identifies the purpose
of science not as description but as manipulation. Laws are not
cognitive statements about nature, but are directions for
operating in a laboratory. The do no say what nature has
done; they say what the scientist should do. Thus even among
professional scientists themselves, the old view that sci3ence
achieved the “real truth” about nature, a view which has caused
Christianity so much trouble, seems to be receding into the
past. With or without a priori concepts, science is not a
cognitive enterprise.
That science is not
cognitive, i.e., that science fails to obtain a
knowledge of the laws of nature, is evident to all in the
rapid rate at which previous laws of science are discarded and
replaced by new ones. For example, (1) the law of gravitation
conflicts with the observation of galaxies. It implies that the
universe has a center where the spatial density of stars is
maximum; i.e., more stars per cubic area. Proceeding
outward from this center, the spatial density should decrease
toward an infinite region of emptiness. But observation, of
which the ordinary view of science must depend, shows galaxies
everywhere, and this contradicts the Newtonian law of
gravitation. (2) A similar change in physics is the failure of
the law of inertia because of the non-existence of a fixed point
and the consequent impossibility of determining motion in a
straight line. (3) The emergence of new theories of light are
perhaps a better know example of the replacement of old laws by
new. If the old laws had been discoveries, if they had been
true, if they had described nature, they would not have needed
replacement.
To forestall the reply
that the new laws have now arrived at the truth and, unlike
Newton’s laws, will never need to be replaced, one need only
note the rapid development of science in the very recent past,
the anticipation of still greater change in the near future, and
wonder why the results of the last ten years should be any more
permanent that those of a previous century. (Gordon H.
Clark, Christian Philosophy, Unicoi, Tennessee: The
Trinity Foundation, 2004, page 286.)
