Good start. Two things I think it needs are Johnson's "I refute it thus" [1] and the 60s T-shirt "Reality is for people who cannot handle drugs". Sandy Harris 00:54, 3 April 2011 (UTC)

Or "... science fiction" in another version. Peter Jackson 10:51, 4 April 2011 (UTC)

Thank you Sandy. I'll slowly work my way to Johnson but if you want to create an applicable section, go for it. Thank you for the suggestions. Is there an image for the T-shirt? I imagine that would be a great relief from the seriousness of Plato, to wear it or even to just see the image.--Maria Cuervo 01:08, 3 April 2011 (UTC)

Hayford: I didn't even see that apostrophe in the definition of Reality!

Also Schroedinger's cat and at least two butterflies — Chuang Tzu's and the one in Chaos theory. Sandy Harris 04:23, 3 April 2011 (UTC)

Nice. BTW, I worked for a decade in IT before switching to Philosophy, so I did enjoy reading your profile. I'm a bit of a polyglot and taught myself a few languages. Doing Oracle, perl, php, cold fusion, asp, pl/sql, regX, whatever and anything. Whatever was needed. I've written my own little content management system which by now is pretty old and useless. (So I retired my personal sites that used the program, for now.) I did consider having myself added to the technology workgroup? but wondered if it was too much. At least I could on occasion write articles on Baudrillard or other philosophy-related technology issues that could cross link. Who knows.--Maria Cuervo 04:43, 3 April 2011 (UTC)

Also, Holographic Universe

I'm interested in this (Is it Talbot that wrote on it?) and see certain affinities between it and Plato's cosmology.

Definition for Reality

What I tried to attempt in the definition was one which could be concise and clear yet accommodate vastly different meanings. The definition used works in Platonic Realism but depending on how the terms within it are defined, e.g., being, also with phenomenology.--Maria Cuervo 13:52, 4 April 2011 (UTC)

Saw a quote today, attributed to Einstein "Reality is merely an illusion, albeit a very persistent one." I do not know if that is genuine, but if it is, it belongs in the article. Sandy Harris 14:11, 4 April 2011 (UTC)

I think that a whole page could go Einstein's string theory version of reality v. the holographic version and link back here. This page could become a huge project.

Physicists about philosophy?

Maybe somebody (Anthony?) could explain to me why a couple of physicists have especially noteworthy views on this topic? Basically, they're trying to do philosophy. There are far more important thinkers who talk about the concept of reality.

I'm not trying to start a fight, or disrespect Stephen Hawkings or Anthony of course (I love both!), I'm just rather tired of non-philosophers (Dawkins is another example) being thought of as making important contributions to philosophy, when they're basically just authors who are using their popularity as a platform from which to advance theories, probably without reference to serious philosophers, who do this sort of thing for a living... --Larry Sanger 03:41, 18 July 2011 (UTC)

I know of a couple of physicists who don't know that such a field as philosophy exists, and write about philosophy under the impression that they're writing about physics. Michael Hardy 04:21, 18 July 2011 (UTC)

Hi, Larry. Sorry to hear you're "rather tired of non-philosophers...being thought of as making important contributions to philosophy...". I guess you can view Hawking and Mlodinow as being thought of as contributing to philosophy. Actually, when it comes to science, you can't do philosophy very well if you don't understand the science, they argue. Nobody understands quantum reality, but some scientists spend their lives learning as much as they can about it. Many are philosophers at heart, and contribute insights to questions that can't be answered by science alone. The first philosophers were philosophers of nature, but not scientists. The latest philosophers are both. I could not label Stephen Hawking a non-philosopher. Perhaps 'metascientist'? Anthony.Sebastian 04:27, 18 July 2011 (UTC)

Um, this article is called reality, not philosophy? I hope Larry isn't trying to suggest that the only people who can have views on reality are people with philosophy degrees. That in itself seems to be a somewhat anti-scientific view. David Finn 06:03, 18 July 2011 (UTC)

Reality is a philosophical concept. CZ is an expert-based site, or academic-based, maybe, but not specifically science-based. Look at the workgroup list.

On the particular topic in question, I don't think Hawking & co are saying anything particularly new. You'll probably find it all already in philosophers of science. Yes, of course you can have different theories giving the same empirical predictions. Usually scientists choose between them on the basis of usefulness, e.g. simplicity. For example, there are versions of creationism and intelligent design that are empirically indistinguishable from standard evolutionary theory. They're just not very useful, and probably more complicated (if God makes things happen as if they evolved through natural selection, then the entire theory of natural selection would have to be implicitly present in his mind, so these theories contain the other in toto, with additions). Peter Jackson 15:04, 20 July 2011 (UTC)

I see the article is listed in philosophy and classics workgroups. I don't think the EC has yet worked out a policy on workgroups. Peter Jackson 15:08, 20 July 2011 (UTC)

What might be more interesting to cover is the philosophical implications for the concept of reality of quantum mechanics. What you've got there is a complicated mathematical formalism that doesn't seem to "describe" anything one might want to call "reality". You might say it does nothing but predict the results of experiments (correctly), without explaining why the experiments have those results in any way we can understand.

For example, it says "If you do this experiment, you can measure position. If you do that, you can measure momentum. But you can't do both experiments. If you do this experiment you'll observe a particle. [That is, you'll get the sorts of results you'd expect to get if there were "really" a particle there.] If you do that you'll observe a wave." So what is "real" here? Is there a particle, or a wave, or both, or neither? Has it got a position, or a momentum, or both, or neither? There are "hidden-variable theories" that describe some sort of reality and give the same experimental predictions, but physicists don't seem to find them useful. Peter Jackson 15:18, 20 July 2011 (UTC)

There are articles about the physicist Niels Bohr in multi-volume encyclopaedias of philosophy. I haven't tried looking up Hawking. Peter Jackson 15:19, 20 July 2011 (UTC)

I will try to come up with a list of scientists widely regarded a philosophers of science. Anthony.Sebastian 20:13, 20 July 2011 (UTC)

Mathematics and Reality

[Mathematics and Reality http://ukcatalogue.oup.com/product/9780199280797.do Mathematics and Reality] reviewed here and discussed in the Stanford Encyclopedia of Philosophy here is a recently published (2010) book that might be of interest for this article. The author is Mary Leng - my niece, so I declare an interest and won't insert any details myself. (She, unlike me, is a 'proper' philosopher, Larry.)Gareth Leng 15:35, 21 July 2011 (UTC)
