Essay Abstract

In this essay, I argue that the idea that there is a most fundamental discipline, or level of reality, is mistaken. My argument is a result of my experiences with the "science wars", a debate that raged between scientists and sociologists in the 1990's over whether science can lay claim to objective truth. These debates shook my faith in physicalism, i.e. the idea that everything boils down to physics. I outline a theory of knowledge that I first proposed in my 2015 FQXi essay on which knowledge has the structure of a scale-free network. In this theory, although some disciplines are in a sense "more fundamental" than others, we never get to a "most fundamental" discipline. Instead, we get hubs of knowledge that have equal importance. This structure can explain why many physicists believe that physics is fundamental, while some sociologist believe that sociology is fundamental.

Dear Matt,

you present an intriguing point of view. It's interesting to think about how the spectrum of opinions would look if this contest had taken place at the height of the science wars---I would imagine many more of the physicists would defend a reductionist 'orthodoxy'. As it is, I think it's very refreshing to see that, at least among physicists entering FQXi contests (which may be a...

Against the measure of survival, both physics and sociology obey the biological Darwin selection process. Human history has shown a trend to focus to common solutions to sociological structures. Tribes, chiefdoms seem to have nearly the same structure and operation across many geographies. We're still working on states and nations and a world order. We might expect another planet would have the same sociological solutions.

Dear Matt Leifer,

It's good to see you back. I think your network model (figure 1) is somewhat related to the two essays on 'meaning' (Brian Josephson and Todd Duncan). I suspect you are correct about the scale-free structure of human knowledge. If so this would seem to have some implication for brain/mind models. I too think alien physics would resemble ours.

One example you treat is Einstein's special relativity. You argue that perhaps Einstein's theoretical explanation of the symmetry of Maxwell's equation contributed to his acceptance. My current essay contrasts this with the Maxwell-hertz equations that he actually referred to in his 1905 paper. I hope you will find time to read my essay and comment in this regard.

Best wishes and good luck in your quest for #2.

Hi Matthew,

Thanks for your personal account sociology of science. I fully agree with you that the content of physics is not entirely contained in its mathematical equations. And that “the scientific method” cannot be characterized in a precise way that is applicable in all cases. Different scientific disciplines use different methods and standards of evidence, as you state. Sadly this is also true in physics. Specifically in fundamental physics. What can account as evidence or true has to be sorted out within the physical community. Your theory of knowledge also nicely shows why specific disciplines see locally a hierarchical structure.

When I studied physics, I also attended curses in sociology of science. But I never got really happy with it, because they seems not to be able to explain the great success and unity that underlie our best physical theories.

Recently in philosophy of science I learned something about Quine’s holism, who has also a short appearance in my essay The quantum sheep - In defence of a positivist on physics. I show that in any realistic theory there is not only an underdetermination of the theory by the data, but also a conceptual underdetermination, where it is not clear within the theory, which assertions are analytic (definitions) which are synthetic (observational consequences). There are always conventional elements.

I also provide an Copenhagen type of interpretation of the quantum measurements problem, which I really would like you to read and comment, since I know, you are very critical about the different Copenhagen views.

Hi Matt,

I was skeptical at first, but you made a quite reasonable case... so it must be a good essay!

Still, you seem inclined to think there's probably one efficient scale-free network (or a close family of similar ones). Wouldn't it follow that the most important hubs in such a network were really "fundamental" in their own right? I know that's a different question than the one you're addressing here, about entire disciplines, but to me that still seems like a reasonable application of the term.

Best, Ken

Dear Prof. Leiter,

I loved your essay; I am just sorry I haven't spotted it before.

Maybe it has a bit of a bitter conclusion, and I am not sure whether I agree on every idea you have expounded, but it is surely fresh air in this contest. Your personal account of the "science wars" is very ejoyable. My essay also point out a failure of physicalism, and although I am maybe less radical in considering that the question '"what is fundamental?” simply evaporates', I argue for a search for fundamentaly that is methodology-dependent. I would be most glad if you find the time to have a look at my essay as well (https://fqxi.org/community/forum/topic/3017) that shows some similiraties, but also divergent points, that I would willingly discuss with you.

Meanwhile, congratulations for one of the best essays. 10 out of 10!

All good wishes,

Flavio

Dear Matt,

I enjoyed reading your essay "Against Fundamentalism". Clearly it is very tempting for physicists to see their discipline as more fundamental, and in a sense it is true. I agree that sociological context influences significantly the trajectory of physics. I think history plays a role in our choices not only in the formalism, but also in the preference of one theory over another. Your example with the Copenhagen interpretation seems to me very representative. Also the discussion of the Michelson–Morley experiment, which luckily was confirmed recently with an impressive degree of accuracy at the 10-17 level.

The free-scale network seems to be quite universal, and I think your picture of knowledge as such a network is relevant. I believe there is a relativity of fundamentalness in science, but also in fundamental physics.

Given that (1) the scale-free network applies to so many situations, including, as you propose, to scientific knowledge, and given that (2) all information we have is extracted by observation ultimately from the quantum state, do you think that it is possible that (3) there is nothing but a huge it-from-bit network originating from and consistent with the laws of quantum mechanics? I don't mean in a reductionistic way, but in a participatory way.

Best wishes,

Hi Matt,

Thanks for this. Your network picture reminded me a great deal of the web of belief W.V. Quine proposes in his essay "Two Dogmas of Empiricism."

You seem to construe physicalism, the claim that physics is fundamental, as the view that, in your words, "In principle, we could use fundamental physics to predict with the greatest possible accuracy what will happen in any given situation, including those relevant to chemistry and biology, and even in those sciences that deal with the human mind, such as neuroscience, psychology, and sociology." But I don't see how the conclusions of the strong program really interact with that. We may have sociological explanations for the uptake of physical theories over time. But this doesn't rule out that there may be more fundamental physical explanations of those same events, as you say, "in principle."

Best,

Alyssa

Matthew,

Quite an interesting essay, one I would not expect from a physicist, unless exposed to a broad range of subjects and influences. It got me to thinking about what my single hub node might be. I suppose it might relate to my latest interest in retirement, cosmology, in which I'm not formally trained. My nodes -- in terms of formal training -- might be humanities and economics. My essay, I think shows my passion for cosmology with a mix of a traditional religion, Catholicism, maybe quantum biology, and a healthy skepticism of traditional theories. Maybe an appreciation of aesthetics comes out in terms of humanities. What I'm actually saying is that I hope we are all a mixed bag, not pigeonholing our knowledge, but reading widely and keeping an open mind. That is what you seem to suggest. I like your emphasis on knowledge to extend your network. At least, that is what I'm gathering from your essay.

I give it high marks. Hope you can get to mine.

Jim

Hello Mathew,

To quote you:

"In the throes of intellectual inquiry, it is common to adopt overly extreme views, which later have to be walked back. This happens all the time on the speculative end of theoretical physics, e.g. the claim that the universe is literally a quantum computer [8], or that all entangled systems are literally wormholes [9], or that the universe is made of mathematics [10]. So let’s not hoist all of sociology on the petard of their most extreme proponents, and instead look at the evidence on which their claims are based."

After reading your essay, I will have to give sociology some more respect. Your examples make me shake my head in disbelief. Yes, science can get carried away from being fundamental as can sociology.

Thanks for a very informative essay,

Don Limuti

Mr. Leifer

I fully enjoyed the way you put things together (esspecialy when you speak about theory of knowledge) in a clear picture.

I think further words are useless.

Rate it accordingly.

If you would have the pleasure (and time) for a short axiomatic approach of the subject, I will appreciate your opinion.

Respectfully,

Silviu
