Many of the truly great (Leibniz, Descartes, Newton, etc.) made contributions to all three disciplines. Even today, a theoretical physicist is effectively a practical flavor of mathematician and both physicists and mathematicians dabble in philosophy. Indeed, and any distinction between mathematicians, physicists, and philosophers was drawn by philosophers in the first place, probably in consideration of the former two being, from a philosopher's point of view, applied disciplines (e.g., mathematics as applied logic). Philosophy earns its keep during periods of paradigm shift. It's the discipline you pull out of your pocket for those trips to the drawing board.

Starkess Posted October 25, 2016 Share Posted October 25, 2016 Physics started out as the field of "natural philosophy". I don't think they're inherently at odds at all! I say this as a physicist* whose father is a philosopher, so I may have a somewhat skewed view. *sort of Link to comment Share on other sites More sharing options...

Well, the only thing they share in common is that they are both fantasy. I will say this, the vast majority of scientists, myself probably included, don't really engage with the philosophy of science as much as we should. It is only when you get to the quantum realm though, that philosophical implications become really profound. For instance, the role of the observer in quantum mechanics etc...It also leads to a lot of BS (see Deepak Chopra) that makes many scientists a bit leery of the whole enterprise. There's a lot of chaff out there that's hard to wade through. When it comes to string theory....I think the situation is a bit more dire where some string theorists, lacking experimental evidence, have begun to change the nature of what is broadly considered the scientific method (with the help of philosophers). I think the most dangerous idea is some sort of Bayesianism, where trust in a theory is not binary but has a sliding scale between 0 and 1 in the absence of any empirical evidence.

String theory's entire purview being mathematically described structures that are by definition too small to create empirical evidence. Still, the idea of having a universal substrate for all sub-atomic* particles is a worthy one. And a string theorist is a mathematician, whether or not the math describes reality. ETA: I guess what I'm saying is that string theory is definitely mathematics, but whether it is physics is an open question. It describes physics at least, so does that make it metaphysics? *do I need another word here? sub-atomic would include protons and neutrons, which are a step up.

You dont need to observe strings, there are predictions that can be made with certain flavors of string theory that could have shown up at current LHC energies. Unfortunately, none of these signatures showed up. In the sense that it can make predictions, I think it is still physics, but not particularly relevant physics. I think the metaphysical part comes when people start rationalizing the lack of evidence with changing the very nature of the scientific method itself.

The standards of rigor for mathematicians, and apparently, philosophers in mathematics is much higher than for physicists as well. It also makes for denser reading I suppose. One example I always like to give is that of rain. You can describe the physics of rain much more easily than you can solve the non-linear equations for it.

And, an update: I was perusing the Wiki on analytic philosophy and evidently there is a sub-branch of analytical metaphics called the philosophy of physics, further subdivided into the philosophy of space and time and the philosphy of quantam mechanics. No idea what person in any philosophy department publishes in this area, however. All the citations in the wiki are to theoretical physicists.

It is true that physicists rely a great deal on approximations, but as long as one fully understands the uncertainties associated with the approximation and regions where it is not valid, this is mathematically rigorous (it wouldn't be useful if it weren't). 56 minutes ago, Ariadne23 said: Fair enough.

There are a few (see, for example, this brief list which describes a bit of what Maudlin does). However, on the whole, I wouldn't say philosophy earned its keep in this instance. Quantum mechanics and general relativity were paradigm shifts if ever there were any. We've mastered them to the point where we can have smartphones and GPS satellites, but there's still no universally accepted explanation for what they mean and in fact the most widely accepted ones (and perhaps the best) are still those of the physicists who originally developed them. The philosophers dropped the ball here. Link to comment Share on other sites More sharing options...

The philosophers dropped the ball here. That's pretty persuasive, IMO. People in philosophy tend to start off as pretty open-minded and original thinkers in the first place, and the area of study itself encourages development of those cognitive abilities, but then, like every other academic field, they spend their younger years when fluid intelligence is at its highest earning their chops by jumping on some bandwagon or another, which tamps it down. Plus, people with the quantitative chops to be of use to physics would have next to no practical reason to get a philosophy graduate degree. I can't imagine a less employable academic field than philosophy, even among the economic wasteland that is academia. It'd maybe help if some top tier school developed a joint theoretical physics/analytical philosophy PhD program, if they have not already. Link to comment Share on other sites More sharing options...

Are none of the theories useful for science? I think psychoanalytic theory has a lot to offer here. Simply stated, I'd say consciousness is the ability to form a narrative and place oneself in it. In some ways that makes consciousness the ability to maintain a useful illusion, cognitive dissonance and the like being manifestations of the phenomena.
