Science, Reason, Ethics, and Modern Medicine, Part 2: the Tortured Logic of David Katz

In Part 1 of this series* I asserted that a physician’s primary ethical responsibility is to honesty and integrity, which in turn must be largely based on science and reason (I apologize if that sounded preachy; if there had been more time I might have couched it in more congenial terms). I mentioned the fallacious reasoning whereby proponents of implausible medical claims (IMC) point to real and imagined weaknesses of modern medicine to justify their own agenda. I offered, as a favorite example of such proponents, science-based medicine’s having not yet solved every health problem. This week I’ll show how this version of the tu quoque fallacy has led a prestigious medical school to advocate pseudoscience-based medicine.

Modern Medicine: a Brief, Fragile Commitment to Science

First, a few more words about the title of this series. Modern medicine is not science, even if it draws upon science for its knowledge: it is an applied science similar, in that sense, to engineering. Modern medicine is also not synonymous with the “medical profession,” if the term means the collection of all people with MD degrees. That is true for the obvious reason that medicine is more than people, but also because a small but loud minority of MDs rejects modern medicine and science.

Modern medicine has made an uneven commitment to science and reason. At its best, it has formally embraced them in the faculties and curricula of medical schools, in its codes of ethics, and in its contributions to knowledge, both basic and applied, over the past 150 years or so. As discussed last week, it is because of science and reason that modern medicine has made dramatic, revolutionary advances in a very short time. That is what distinguishes it from every other “healing tradition,” and why there is no legitimate competition. The only valid medicine in the modern world is science-based medicine—not “allopathic,” “Western,” “conventional,” “regular,” “integrative,” “complementary and alternative,” or any of the so-called “whole medical systems.” The pre-scientific (and, ironically, “post-modern”) designation of “schools” or “systems” of medicine, so stridently trumpeted by quacks, is an anachronism—even if it persists in archaic, governmental edicts.

Compared to the actual sciences, however, modern medicine’s commitment to science is fragile. Its recent confusion of error-prone clinical trials with science itself—the project called “evidence-based medicine”—has been a mixed blessing. Its growing tolerance of charlatans and crackpots, at times elevating them to celebrity status, would be unthinkable in physics or biology. Its dalliances with quackery, so depressingly recounted in recent posts here, here, here, and here, are why your SBM bloggers do what we do. Biologists, other scientists, and intellectuals in general have joined the battle against the pseudoscientific travesty known as “intelligent design.” Many physicians, however, even of the brainy, academic variety, act as though the equally pseudoscientific but more dangerous travesty known as “integrative medicine” is either a good thing or, at least, is a necessary addition to medical school curricula.
