Every few months,
But whatever the ostensible subject, and regardless of whether Israel's political leaders and soldiers and spokesmen do their work as they should, we know for certain that the consequence of this future incident, a few months from now, will be another campaign of vilification in the media and on the campuses and in the corridors of power—a smear campaign of a kind that no other nation on earth is subjected to on a regular basis. We know we will again see our nation treated not as a democracy doing its duty to defend its people and its freedom, but as some kind of a scourge. We'll again see everything that's precious to us, and everything we consider just, trampled before our eyes. We'll again have to experience the shame of having former friends turn their backs on us, and of seeing Jewish students running to dissociate themselves from
All this has happened repeatedly, and we know it will happen again. Indeed, these outbursts have grown more vicious and effective with each passing year for a generation now. And there's every reason to think this humiliating trend will continue, with next year worse than this one.
As to the reactions of Jews and other friends of Israel to these smear campaigns—as far as I can tell, the reactions haven't really changed in the last generation either: My friends on the political left always seem to think that a change of Israeli policy could prevent these campaigns of vilification, or at least lessen their reach. My friends on the political right always seem to say that what we need is "better PR".
No doubt,
Nothing could make this more evident than the Jewish withdrawal from
To put this in slightly different terms, it's not the maintenance of a security zone in South Lebanon, or Israeli control of the Gaza Strip, or a raid on a Turkish blockade runner's boat that is reponsible for what is happening to
The rest of this letter will be devoted to trying to get at what that underlying objection to

In 1962, a Berkeley professor named Thomas Kuhn published a book called The Structure of Scientific Revolutions, which went on to become the most influential academic book of the last half century, selling over a million copies in a dozen languages. Kuhn's book dropped a depth charge under the foundations of academic thinking about the way we search for truth, and about the way we come to believe the things we believe. And although the subject of the book is the way the search for truth works in the physical sciences, it has implications well beyond the sciences.
In The Structure of Scientific Revolutions, Kuhn argues that the traditional picture of science—in which scientists conduct universally replicable experiments to accumulate verified facts, which together make up the body of scientific truths—is without basis in the actual history of science. Instead, scientists are trained to see the world in terms of a certain framework of interrelated concepts, which Kuhn calls a paradigm. In the overwhelming majority of cases, the paradigm not only determines the interpretation that a scientist gives the facts, but even what facts there are to be interpreted: The "facts" that scientists consider admissible for discussion are those that easily conform to the dominant paradigm, or that can be made to conform to it by extending the paradigm or introducing minor repairs into it. Those facts that can't be made to conform to the reigning paradigm are overlooked entirely or dismissed as unimportant.
Kuhn was famous, of course, for pointing out that things don't go on like this forever. The history of science is punctuated by shifts in the dominant paradigm, as when Aristotelian physics gave way to Newtonian physics, or when
The proponents of competing paradigms are always at least slightly at cross-purposes. Neither side will grant all the non-empirical assumptions that the other needs in order to make its case…. [Thus while] each may hope to convert the other to his way of seeing…, neither may hope to prove his case. The competition between paradigms is not the sort of battle that can be resolved by proofs.[1]
As Kuhn points out, even a mountain of facts will not change the mind of a scientist who has been trained in a different paradigm, because the fundamental framework from which he views the world is different: The facts themselves mean something completely different to him. In fact, very few scientific paradigms, including the most famous and most successful, are able to provide the kind of decisive experimental evidence that can force scientists to give up the old paradigm.
How, then, do scientists come to change their minds? Kuhn says that in many cases, they never change their minds—and that an entire generation has to pass before the scientific community enters a new paradigm:
How, then, are scientists brought to make this transposition? Part of the answer is that they are very often not. Copernicanism made very few converts for almost a century after Copernicus' death.
Kuhn doesn't go quite as far as endorsing Planck's claim that paradigms change only when the supporters of the old paradigm die off and a younger generation takes their place. But he comes close, approvingly quoting a passage from The Origin of Species in which
Although I am fully convinced of the truth of the views given in this volume…, I by no means expect to convince experienced naturalists whose minds are stocked with a multitude of facts all viewed, during a long course of years, from a point of view directly opposite mine…. [B]ut I look with confidence to the future—to young and rising naturalists, who will be able to view both sides of the question with impartiality.[3]
