Doctors were probably the last group of professionals broadly trusted across all stripes of society. Now, there seems to be no group whom everyone trusts. We have to thank for the destruction of that last bastion of trust the doctors, many of them epidemiologists, who first vehemently clamored for an urgent nationwide shelter-in-place to prevent the spread of COVID-19, only to make exceptions to those restrictions for the nationwide protests and riots following George Floyd's death. So abrupt was their change of mind that one can't help doubt either their intelligence or integrity. Even the most moderate of doctors danced delicately around the issue, refusing categorically to say that protests were as bad an idea as many other activities which were effectively banned and that they too should be at least discouraged.
This hypocrisy I mention for the sake of a complete preface, though I confess it is not surprising to observers of leftist reasoning. More interesting by far, though, is the logic by which many doctors justified their authority to prognosticate on matters non medical: all matters are medical. That is in effect the reasoning behind their self-authorized declaration that "racism (and white supremacy are a public health crisis."
This is a very bold statement that represents a very serious problem: doctors and scientists don't know what science is.
Worse than that, they have taken a partial explanation of scientific process, usually referred to by text books as "the scientific method," to be a full definition of science, scientific paradigms, and the philosophy of science. This preposterous notion of the "scientific method" is one of the 20th century's most pernicious myths.
It is a myth that has found its absurd conclusion in "the scientific method" becoming the only means of inquiry and admitting no bounds or rules. Further it is thought since science tests observable phenomena, observable phenomena must be all there is to test. Any discipline of learning that does not operate by analyzing data and any premise not residing in a materialist understanding of the world is inherently invalid and less important than even the worst scientifically-arrived at conclusion.
By varying types and degrees of this absurd reasoning, doctors and scientists have created a monopoly for themselves on everything, which has led to the recent and inevitable public declarations of excommunicating conservatives from political discourse and of the all-reaching authority of doctors and scientists.
There is also the personal and political angle to all of this, which is that doctors and scientists, who not only politically trend to the left but also were the left's last reserve of authority that could be brought into the battle against Trump, really enjoyed the COVID limelight and flexing their muscles against Trump, the right, conservatives, republicans, and the religious, whom they see as having usurped and brought down America from the pinnacle of reason-governed utopia that Obama raised out of the wreckage of the Bush administration.
It was in fact during the Bush era that I remember scientists inveighing with increasing regularity about "the people in charge of this country" with reference to the administration's positions on global warming, as it was still called then, and stem cells, in particular. Doctors too weighed in on Bush's personality—he could utter nothing without evidencing his duncitude—gleefully pschologizing him as they have done with Trump with predictable verdicts. Most recently of all, doctors have begun publicly to weigh in on Trump's physical health—which they say is ailing—making diagnoses about the president via videos of him.
They have obviously overreached, but I do understand their frustration and desperation to assert themselves, partially because I agree that many and large segments of the right are opposed to science. Conservatives too often: lean on tradition even when good science (and history and theology) contradict it (i.e. on circumcision), use bad arguments (i.e. against climate change), use of common sense not only beyond its limits but overtly instead of logic, repeat conspiracy theories (too many to count, but recently: pizzagate and former President Obama being a Muslim), argue from authority, misquote or selectively quote sources, especially the Bible. . . and on and on and I completely understand why liberals think the right has run amok with unreason. It has.
However, look at the writing not of the fanatical, but of even moderate, progressive, even-tempered folks of the sane leftwing-scientist-doctor-atheist mold, and their works—works of prominent and highly intelligent people—are not only riddled with but founded on errors of history and philosophy.
Left and right the liberal tradition has been run into the ground, which is why the ground troops of the illiberal right and illiberal left are now in a hot war. Meanwhile, the illiberal intellectuals on the right and left are both arguing, very differently of course, that it is the intrinsic problems and contradictions of the classical liberalism that have led to the current crisis, which is now observed to be a full-blown crisis of both politics and, more gravely, philosophy.
