The review of T. S. Kuhn's The Structure of Scientific
Revolutions (Journal ASA 25, 34-8 [1973], by Harry Cook) was disappointing in
several ways. The greater portion of the article was very good, and Kuhn's book
certainly deserves extended study, but some of Cook's conclusions do
not necessarily
follow from his discussion, nor do they accurately reflect Kuhn's position.
Cook claims that Kuhn has given an unambiguous, extremely subjective answer to
the question, "What is it then that structures reality, that
makes it dependable,
investigable, or consistent?" Actually, Kuhn does not answer this question
at all. In fact, he insists that "it need not be answered in this place.
Any conception of nature compatible with the growth of science by
proof is compatible
with the evolutionary view of science developed here" (p. 173).
The Structure of Scientific Revolutions is a discussion of modes of perception,
not of underlying reality. The statement "Whatever be may see,
the scientist
after a revolution is still looking at the same world" is not
then a retreat.
It is rather a hint at a possible answer to Cook's question. Nor does
Kuhn totally
disregard the concept of "Truth" in favor of relativism: it most be
remembered that he is writing in an historical context in which the problem is
irrelevant.
Elsewhere, Kuhn has described the aim of science as seeking to "explain in
detail a range of natural phenomena." Similarly, Cook has said, "It
is the business of the scientist to investigate this structure which holds for
reality, and he should attempt to formulate laws or theories which reflect
this structure." But the mere fact (Heb. 11:3) that this
structure of reality
is created and upheld by the Word does not guarantee its total
comprehensibility (Isa. 55:8-9), let alone its status as a teleos for science. It is
through interaction
with this structure that man evaluates the reflection he has created in his own
laws and theories. Kuhn does not suggest "progress toward a non-existent
goal!" in a struggle where only the fittest theory survives
because it "leads
to the most progress". Rather it is a gradual increase in articulation of
scientific theories and practices brought about through an interaction of the
mind of the scientist with the material world. There is a physical
basis for the
paradigms of science, but there is no way in which these paradigms
could be said
to be formed through "direct observation" of a material reality.
A less sophisticated, but very interesting model could be
used at this point. At the end of The Discarded Image. C. S.
Lewis discusses the "truth" of different scientific
worldviews. He notes
that, "Here, as in the courts, the character of the evidence
depends on the
shape of the examination, and a good crossexaminer can do wonders. He will not
indeed elicit falsehoods from an honest witness. But, in relation to the total
truth in the witness's mind, the structure of the examination is like
a stencil.
It determines how much of that total truth will appear and what pattern it will
suggest."
Cook would have done well to consult the "Postscript-1969"
of the second edition of The Structure of Scientific Revolu
tions since Kuhn defends himself against many of his critics. There
are also three
articles which will be very helpful for those who wish to better
understand Kuhn's
view: J. J. Kockelmans, Philosophy Forum 11(1972), 231-52; D. A.
Hollinger, American
Historical Review 78 (1973), 370-93; J. F. Miller, Religious Studies 5(1969),
49-68. Although I would not suggest that everything in these articles
is theologically
tenable, they do cast a great deal of light on Kuhn's general premises.
