A Kind of Perceived Truth

Excerpted from The Great Influenza by John M. Barry,  © 2004:

Indeed, methodology matters more than anything else. Methodology subsumes, for example, Thomas Khun’s well-known theory of how science advances. Kuhn gave the word “paradigm” wide usage by arguing that at any given point in time, a particular paradigm, a kind of perceived truth, dominates the thinking in any science. Others have applied his concept to nonscientific fields as well.

According to Kuhn, the prevailing paradigm tends to freeze progress, indirectly by creating a mental obstacle to creative ideas and directly by, for example, blocking research funds from going to truly new ideas, especially if they conflict with the paradigm. He argues that nonetheless researchers eventually find what he calls “anomalies” that do not fit the paradigm. Each one erodes the foundation of the paradigm, and when enough accrue to undermine it, the paradigm collapses. Scientists then cast about for a new paradigm that explains both old and new facts.

But the process– and progress– of science is more fluid than Kuhn’s concept suggests. It moves more like an amoeba, with soft and ill-defined edges. More importantly, method matters. Kuhn’s own theory recognizes that the propelling force behind the movement from one explanation to another comes from the methodology, from what we call the scientific method. But he takes as an axiom that those who ask questions constantly test existing hypotheses. In fact, with a methodology that probes and tests hypotheses– regardless of any paradigm– progress is inevitable. Without such a methodology, progress becomes merely coincidental.

I bought the book on a whim, then kicked myself for spending money a what I thought would be a very dry exposition about stuffy people with headaches.

My first impulse was the correct one.  The context is broad, the problems fascinating, the writing brilliant.  I would recommend this book for almost anyone.

  1. I especially like “In fact, with a methodology that probes and tests hypotheses– regardless of any paradigm– progress is inevitable. Without such a methodology, progress becomes merely coincidental.”
