Well perhaps the problem is just the way the article is written. It sounds as if Harriman is opposed to any speculation or theorizing at all. What’s wrong with speculation as long as you acknowledge that your ideas must be confirmed by observations to be accepted?
posted by GreedyCapitalist: “Today’s physicists on the other hand, reject the existence of an objective reality as such, and thus do not believe that it is necessary (or possible!) to show that their nonsense corresponds to any fact of reality.”
Sorry, but this is just not true. I challenge you to show evidence that any substantial number of physicists “reject the existence of an objective reality”. I spent 3 years at the Institute for Advanced Study in Princeton (my wife did her postdoc there). I met a number of people doing cutting-edge theoretical work in astrophysics and string theory. Much of their work was speculative, but none of them doubted that reality is objective or thought that it didn’t matter whether or not their ideas conform to reality.
By the way, according to the op-ed Harriman has an M.S. in Physics, not a PhD. In science, an MS is basically a consolation prize given to people who don’t finish their PhD.
No, you’re not misreading the article. He is indeed (I assume) opposed to any of what you mean by “speculation” at all. The reason why is that you can speculate all day, but if you start with that, it’s pretty difficult to determine whether or not the theory is true: it’s generally impossible to _dis_prove it, since you can’t prove a negative, but on the other hand any scrap of evidence that seems to conform to the theory is taken as support for it. But it shouldn’t be, since that correlation is not backed up by an appropriate understanding of the causal factors involved. The proper way to form a scientific theory is by a proper method of inductive generalization based ultimately on direct observation via sense perception. Sense perception is our only tie to reality, so if you don’t begin there and work toward more abstract conclusions, always keeping every intermediate step firmly tied to reality, you’re never going to know whether your theories are true. That’s not to say that it isn’t possible to start with a theory, then based on actual evidence induce that theory later; but it’s highly unlikely, and if you do that then the original speculation was unnecessary anyway.
And as far as today’s physicists rejecting objective reality, well of course most of them will deny it and say that they believe reality is objective, but at the same time they pose ultimately groundless theories about “multiple universes” (a direct contradiction in terms) and stuff like that which undercut the idea of an objective reality at its root. Nevertheless, it’s not the content of their ideas but their method which is truly wrong.
And I can’t help but get the feeling that they sit around doing this arbitrary speculation just to get federal grant money paid for by my taxes–which is just as bad as federally subsidized modern art (and for the same reasons). Certainly they’re not motivated by a true quest to know the nature of reality, because they never consult it by following a proper scientific method.
And if an MS in science is basically a “consolation prize” (although I don’t think that that’s necessarily true), I wonder why he didn’t get the PhD when the clowns running the show are these rationalists who not only don’t bother to look at reality very often, but often actually evade it.
