I'm a Leibnizian on this, and have given maybe five or six talks on this topic over the last year or so. I agree with the formulations given by physicists: e.g., Wald's standard formulation in his 1984 textbook, General Relativity: <br /><br />http://m-phi.blogspot.co.uk/2013/06/walds-formulation-of-leibniz.html<br /><br />But modern Leibnizianism and "sophisticated substantlvalism" are extremely close, and it's quite hard to see what they differ on. Technically, it concerns whether isomorphic spacetime models $(M, g)$ and $(N, g^{\prime})$ represent the same worlds or not (physicists say they do) and what to make of this for the status of the spacetime points themselves. This is a hard conceptual problem.<br /><br />However, on any such clarification, the premise<br /><br />(Phys) Space isn't Euclidean 3-space.<br /><br />comes out true. For example, each spacetime model $(M, g, T, \dots)$ solving Einstein's equations represents a world (and any two isomorphic ones represent the same world); and, usually, (the spatial part of) $M$ is not diffeomorphic to $\mathbb{E}^3$.<br /><br />So, here, I don't think that challenging (Phys) will work, as substantivalists and Leibnizians say more or less the same thing.<br /><br />Cheers,<br /><br />JeffJeffrey Ketlandhttps://www.blogger.com/profile/01753975411670884721noreply@blogger.comtag:blogger.com,1999:blog-4987609114415205593.post-44467579034446276682013-07-04T10:26:35.414+01:002013-07-04T10:26:35.414+01:00Hi Brian.

As you already noticed, originally this was more or less my suggestion too; and it still attracts me somehow. The problem is as to how to express this suggestion so that it works. <br />After a little thinking on this, it turns out that, whatever is the meaning of the term 'space' in (Phys), the contradiction will still remain unresolved; and rightly so. Specifically, the contradiction will be there also whatever is the type of the term 'space'; that is, for any possible "semantic unpacking" - if I take your comment correctly. Indeed, assume the type of 'space' in (Phys) is different from the type of 'space' in (KTS). Then trivially, what the former 'space' means cannot be what the latter 'space' means. Hence, the former 'space' is not the form of external intuition. And this contradicts (KTS). <br /><br />So I eventually concluded that it was a flawed suggestion after all. <br /><br />Any thought? <br /><br />Cheers, <br />AntonioAntonio Negrohttps://www.blogger.com/profile/08533947260637745377noreply@blogger.comtag:blogger.com,1999:blog-4987609114415205593.post-64722128716902559352013-07-04T09:08:26.231+01:002013-07-04T09:08:26.231+01:00I don't think it's a translational issue, ...I don't think it's a translational issue, Jeff.

Roughly,<br /><br />(Psych) The form of external intuition is E^3.<br />(Phys) Space is not E^3.<br />(KTS*) Space is *represented* (approximately) by the form of external intuition.<br /><br />Then, everything, including the modification of Kant's theory of space, is ok. The mind's external intuition has some form (i.e., a structural mental representation which is, or somehow generates, E^3, and thus grounds our a priori synthetic knowledge), and then this form represents, albeit not 100% accurately, space. <br /><br />This is consistent, and (KTS*) is, so far as we can tell, true. But then it doesn't yield (TI), because although perhaps the representation, the external intuition, its form, etc., can't exist mind-independently, still the referent of a representation can, particularly if it's a misrepresentation. The mind's cognitive system generates (I'd guess largely innately) an a priori representation, and this is, or yields, E^3 (though no one quite knows how). This mental representation of space is a good approximation as a representation of what space is. But, crucially, it is still not 100% correct, because what space is isn't what our mental representation says it is. For (TI), Kant needed space to be our mental representation ("the form of external intuition"); but then physics eventually said: no, they're, very probably, different.<br /><br />Cheers,<br /><br />JeffJeffrey Ketlandhttps://www.blogger.com/profile/01753975411670884721noreply@blogger.comtag:blogger.com,1999:blog-4987609114415205593.post-44978267763646080592013-06-29T20:12:41.022+01:002013-06-29T20:12:41.022+01:00Hi Jeffrey, thanks. :) Yes - the inconsistency is ...Hi Jeffrey, thanks. :) Yes - the inconsistency is definitive, of course.

The prima facie problem is that extending three inconsistent claims with a definition can't make it consistent. (Kant might even have thought "space is the form of external intuition" is a definition!)<br />The only way to make the inconsistent set of three sentences consistent is to change the word "space" in Kant's theory of space to another word, say W. <br /><br />But this implies that all of Kant's translators mistranslated his word "Raum". And what would this word W be?<br /><br />Cheers<br /><br />JeffJeffrey Ketlandhttps://www.blogger.com/profile/01753975411670884721noreply@blogger.comtag:blogger.com,1999:blog-4987609114415205593.post-20873076388167627572013-06-29T19:23:46.138+01:002013-06-29T19:23:46.138+01:00Here I think there is a intellectual domain proble...Here I think there is a intellectual domain problem with comparing the understanding of physics with the nature of physics itself, and the same with psychology. We can't assume that our present beliefs constitute the nature of matter or mind.<br /><br />But what I really mean, is that E^3 is not always necessarily external to the psychologist; according to the view that every-thing has it's own mind, that such minds are embodied in matter might be a sheer coincidence. Consequently it is entirely open to interpret intuition as non-intuition, and space as non-space, etc. If there is such a radical contingency as this, there is no saying that there is an overlap between physics and psychology when they refer to the word 'space' or 'time'. These might be utterly separate majesteria, by virtue of the idea that both are interpretations.<br /><br />I don't think that Kant would say that psychology is immaterial, but neither would he say that matter must be psychological. The notion of intuition might involve some degree of extreme independence from definitional certainty. And it is going still further to suggest that physical formulae as they are conceived by mathematicians have any direct psychological bearing, except in extreme degrees of complexity. External intuition, as simple as it seems, might be as far from quantum mechanics as quantum mechanics is from relativity. And, afterall, there has not been a grand unified theory that I know of. In some sense, physics is still obverving discrete areas, which are not identical, even within that discipline. And that is still further not to say that physics has 'discovered everything'. Psychology is one of the disciplines that says consistently that we do not fully understand ourselves, to say nothing of the nature of the external world.<br /><br />What if, for example, the exterior is vastly contingent on the interior, such as in a case of being 'parsed by the universe'? Physical law would be determined to be a corollary to interior truths, not theorems in any permanent sense of the word. Then it is announced that theorems define mathematics permanently, and this rejects outright (assumes) that exterior intuition does not exist. It's a very typical problem in mathematics, that it makes assumptions. For example, the second zero is assumed to be decimal, but decimal is a small detail compared to things like pi and relavity. The decimal system is vastly more contingent and uncertain, unless we determine that mathematics is itself a form of 'external intuition'.<br /><br />I don't place much cachet in the idea of external intuition. I'm a believer in vast complexities and unrealized truths. Saying the world is a product of the mind is a trick of words. For there is no way of saying that mental-physical-things-rendered-real are not themselves material entirely, and if so, there is no way of guaranteeing that that materiality does not itself have mastery over the mind. If that is the case, it is a semantic difference what is meant between some psychological theories of space and time, and similar or opposite theories put out by mathematicians. Both can be observed, or not. Neither is changed by nomenclature, unless in some subtle and specific way.<br /><br />Nathan Coppedgehttps://www.blogger.com/profile/13272730626911068222noreply@blogger.comtag:blogger.com,1999:blog-4987609114415205593.post-24130445717860383222013-06-29T19:09:10.053+01:002013-06-29T19:09:10.053+01:00Hi Jeffrey,

Because then it seems to me that Kant can escape refutation unless you can show that what is meant by 'space' in (Phys) is the same as what Kant means by it. If, for example, Poincaré has convinced us (as well he might) that we ought to be conventionalists about applied geometry and use whichever is most convenient/parsimonious, then I suppose we'd lost any claim to the thought that Physics shows us what space "really" is.

You've hit the nail on head th...Thanks, Brian,<br /><br />You've hit the nail on head there, for I think the Leibniz vs Newton issue is what lies behind Kant's view of space, and how Kant arrives at (TI). But on the underlying question, no - I'm an <i>anti-substantivalist</i>, and what's formulated here is certainly compatible with that. And this rejection of substantivalismt is actually my main interest here too, as I'm interested in the relationism/substantivalism debate as it reappears in modern physics, and not Kant's (TI) view per se. (I've put up various posts here on "Leibniz Equivalence".)<br /><br />Before CPR, Kant was a Leibnizian relationist as against Newton's substantivalist: <br /><br />(L) S = the abstract form of the spatial relations of material bodies. <br />(N) S = an enclosing absolute container in which material bodies were "located".<br /><br />But then, under Hume's empiricist attack, Kant concluded that relationism (L) made space <i>unknowable</i>: i.e., not deducible from sensory impressions. So, for epistemological reasons, in order for space to be knowable (indeed, a priori knowable), Kant replaced (L) by his own Idealist account,<br /><br />(K) S = the form of external intuition<br /><br />(And similarly for time.)<br /><br />From this (TI) then follows, assuming external intuition is mind-dependent, etc.<br />So, that's how I see all this.<br /><br />On the question though, I think ordinary physics and psychology (rather than meta-theories about physics and psychology) are incompatible with "space is the form of external intuition", because together they imply that space isn't the form of external intuition. <br />We just need the psychological and physical premises, <br /><br />(Psych) The form of external intuition is E^3.<br />(Phys) Space is not E^3.<br /><br />Then these scientific premises imply that space is not the form of external intuition.<br /><br />Cheers,<br /><br />JeffJeffrey Ketlandhttps://www.blogger.com/profile/01753975411670884721noreply@blogger.comtag:blogger.com,1999:blog-4987609114415205593.post-68566018399649970462013-06-28T11:26:17.917+01:002013-06-28T11:26:17.917+01:00All of this seems to be a consequence of a tacit a...All of this seems to be a consequence of a tacit assumption that substantivalism about space (or, if you prefer, spacetime) is both coherent and true.

Let me explain a bit better what I'm thinking. To show that the most important difference between the positions of a mathematician and of a physicist is that the mathematician is in much more direct contact with reality, Hardy wrote: "a very little reflection is enough to show that the physicist’s reality, whatever it may be, has few or none of the attributes which common sense ascribes instinctively to reality. A chair may be a collection of whirling electrons, or an idea in the mind of God: each of these accounts of it may have its merits, but neither conforms at all closely to the suggestions of common sense". In this perspective, if one takes the view on space within such common sense and refine it into a transcendentally idealized form (what Kant seems to do), then "the form of external intuition" needn't be the "the referent of external intuition", where the latter has those properties that physics tells us (and yes, this is the meaning I'm giving to "as conceived by physics" :) ) I'm not saying this is Kant's view (arguably, the opposite - since he wanted to offer a theoretical justification of Newton's laws), but still it seems to me that one can agree with Kant's account of our intuition and modern physics at the same time.Antonio Negrohttps://www.blogger.com/profile/08533947260637745377noreply@blogger.comtag:blogger.com,1999:blog-4987609114415205593.post-62868431606747496852013-06-27T20:02:33.992+01:002013-06-27T20:02:33.992+01:00Oops - I should have added also that,

Isn't Kant free to insist that,...Thanks, Anon,<br /><br /><i>Isn't Kant free to insist that, if the physics tells us that space has n dimensions, then the form of external intuition is not as it appears to introspection</i><br /><br />This might be ok; but it looks now, on this interpretation, that <br /><br />"the form of external intuition" <br /><br />means <br /><br />"the referent of external intuition", <br /><br />in something like the modern sense of theories of mental representation. <br /><br />But I'm pretty sure Kant didn't mean that. For if it did mean that, the argument for (TI) would not go through. That is, we'd lose the link between the form of external intuition and being mind-dependent. Or, to put it another way, if it did go through, then all referents of mental representations would be mind-dependent! A very easy way to get a kind of idealism, and to be honest, I think it's a bit like McDowell. And though it's ages since I read Russell's criticisms of Idealism, I think Russell attributes to them precisely the view that all referents of mental ideas are themselves mind-dependent.<br /><br />On the other point, I think Kant already gave that argument! And Brouwer did too, as I understand Brouwer.<br /><br />Cheers,<br /><br />JeffJeffrey Ketlandhttps://www.blogger.com/profile/01753975411670884721noreply@blogger.com
