Kuhn’s Insight – John Polkinghorne and The Value of Value

Posted on by

In my last post, I declared victory for Scientific Realism over Positivism on the grounds that even if Positivism is right, it’s first “prediction” must always be that we ignore it as “truth” – at least to some degree – and be committed to our theories a “the truth” or else we can’t make scientific progress.

I therefore declared that on the point that Kuhn and Popper disagree, that Popper wins by default.

However, Kuhn had many insights that Popper missed or downplayed that help fill in the explanation gaps in Popper’s own theories. One of these is the fact that “refutation” really only happens between two (or more) competing theories. While Popper does not deny this, he really didn’t make it as clear as Kuhn either. We will eventually see that this insight is a key point in understanding the value of Theology.

Another explanation gap that Kuhn fills for Popper is explained in this quote:

Fortunately, there is also another sort of consideration that can lead scientists to reject an old paradigm in favor of a new. These are the arguments, rarely made entirely explicit, that appeal to the individual’s sense of the appropriate or the aesthetic – the new theory is staid to be “neater,” “more suitable,” or “simpler” than the old.

Popper’s Response to Kuhn

Posted on by

In my last post I reviewed Kuhn’s ideas on how the growth of scientific knowledge takes place. I found that, contrary to popular belief, Kuhn and Popper have more in common than they have different. Both deny all the popular notions of science as being based primarily around use of observation to refute the current theory. Both also deny that scientists are ‘objective’ in the usual sense. Both also agree that this lack of ‘objectivity’ is a good thing for the community as a whole.

What I did not have space for, in my last post, was to give some of Popper’s responses to Kuhn.

Unfortunately, Popper initially misunderstood Kuhn. His initial impressions were more like the popular portrayal of Kuhn as someone that did not believe in the growth of scientific knowledge at all. However, Popper – being Popper – eventually came to accept that he had probably misunderstood Kuhn. (See Myth of the Framework, p. 63, note 19)

However, even with some misunderstandings in mind, Popper’s responses to Kuhn are enlightening.

Kuhn vs. Popper: Kuhn’s Challenge to Popper

Posted on by

In my last post, I wrote somewhat glowingly of Popper’s epistemology based on Conjecture and Refutation. In a previous (older) post on Millennial Star I even went so far as to explain why I felt there were some touch points between conjecture and refutation and the Gospel. To summarize, Popper believes all knowledge of all types growths through a process of having problems, conjecturing solutions to those problems, then refuting those conjectures based on the discovery of new problems. Through this process we ‘evolve’ our explanations and they improve over time. The end result is increasing verisimilitude – i.e. closeness to reality – of our knowledge. (I note here that this produces increasing verisimilitude without use of induction.)

Now I will consider the strongest challenger to Popper’s epistemology as elucidated by Thomas S. Kuhn, author of The Structure of Scientific Revolutions. Popper and Kuhn are often considered to be two dynamically opposed views of scientific growth that are in struggle for the heart and soul of science. (See, for example, this book here. I have not read it and don’t intend to.) In actuality, Kuhn and Popper have far more in common than they have different from each other. But Kuhn’s view of science does ultimately pose a threat to the very concept of Scientific Realism and proposes, in it’s place, a Positivist view of the world as our ultimate reality.
