前面的讲话,很真诚,很感人。
看到她,穿着婚纱,一个人慢慢走上长长的红毯,觉得非常难过。
最后,她走到就要关闭的大门前面,慢慢转身,面带笑容,大声喊出拜拜,潇洒挥挥手,画面也慢慢褪色,变成黑白。
就忍不住哭了。

我在时间尽头等你作文1200字英文回答:Waiting for you at the end of time.Time is an abstract concept that governs our lives. It is both relentless and unforgiving, ticking away without pause. As I sit here, contemplating the idea of waiting for you at the end of time, I can't help but wonder what it would be like.If I were to wait for you at the end of time, it would mean that I am willing to wait for eternity. It would mean that no matter how long it takes, I will be there,patiently waiting for you to arrive. It is a commitmentthat goes beyond the boundaries of time itself.Imagine a world where time has lost all meaning. Days turn into weeks, weeks into months, and months into years. Yet, I remain steadfast in my resolve to wait for you. Itis a testament to the depth of my love for you, a love that transcends time and space.In this timeless realm, I would find solace in the memories we have created together. Our laughter, our tears, our shared experiences would be my constant companions. They would remind me of the bond we share, and give me the strength to carry on.But waiting for you at the end of time is not without its challenges. It requires a tremendous amount of patience and perseverance. There will be moments of doubt and uncertainty, when the weight of time bears down on me. Yet, I will remain steadfast, for I know that you are worth the wait.中文回答:在时间尽头等你。

时间的尽头英文版The End of Time.In the vastness of the universe, where galaxies dancein a never-ending symphony, the concept of "time" remains an enigmatic and elusive entity. It is the invisible thread that connects the past, present, and future, shaping the destiny of all creatures in existence. However, what if there were an end to time itself? Would the universe cease to exist, or would it embark on a new journey beyond our comprehension?The quest for the end of time has fascinated philosophers, scientists, and theologians for centuries. It is a question that challenges our understanding of the fundamental laws of nature and the very essence of existence. In this essay, we will delve into the mysteries surrounding the end of time, exploring various theories and perspectives that have been proposed throughout history.One of the earliest theories regarding the end of time comes from ancient civilizations. Many ancient cultures believed that time was cyclical, with the universe undergoing repeated cycles of creation and destruction. In this view, the end of time was seen as the end of a particular cycle, marking the transition to a new era or era of existence. This cyclical view of time was reflected in various mythologies and religious beliefs, often associated with the idea of a "golden age" followed by a period of decline and eventual renewal.However, with the advent of modern science, thecyclical view of time was largely discarded. Instead, scientists began to view time as a linear progression, with a distinct beginning, middle, and potentially an end. One of the most famous theories regarding the end of time comes from the field of cosmology, specifically the theory of the Big Bang. According to this theory, the universe began with a cataclysmic explosion billions of years ago, and has been expanding ever since. If this expansion continues indefinitely, the universe will eventually become so vastand sparse that all matter and energy will become effectively isolated from each other.。

that a Machian perspective enables one to solve the problem of time in quantum ge-ometrodynamics (by saying that there is no time!).I concentrate on his recent book The End of Time (1999).A shortened

research has for some thirty years focussed on Machian themes in the foundations of dynamics.There have been three main lines of work:in classical physics,quantum physics,and history of physics—as follows.He has developed novel Machian theories of classical dynamics (both of point-particles and fields),and given a Machian analysis of the structure of general relativity;(some of this work was done in collaboration with Bertotti).As regards quantum physics,he has developed a Machian perspective on quantum geometrodynamics;this is an approach to the quantization of general relativity,which was pioneered by Wheeler and DeWitt,and had its hey-day from about 1965to 1985.More specifically,Barbour proposes that a Machian perspective enables one to solve an outstanding conceptual problem confronting quantum geometrodynamics,the so-called ‘problem of time’.In short,his proposal is that there is no time!(Hence the title of this book.)As regards history,he has uncovered thetangled tale of the reception(and often misinterpretation)of Mach’s ideas in twentieth century physics(including general relativity);and also written a two-volume history of the theory of motion,stretching from the ancient Greeks to the twentieth century.Barbour has now written what is in effect an intellectual autobiography,in the form of a book of popular science([1999]:page references are to this book).It covers all three of his lines of work.It of course emphasises thefirst two,especially the second(the speculative proposals about quantum gravity).The work on classical physics is discussed in Parts2and3of the book;and the quantum speculations in Parts1,4and5.But Barbour also weaves in a considerable amount of historical material.Although it is a popular book,there are three reasons,of increasing importance,to review it in this Journal.Thefirst relates to the style of the book:it is not a hack popularization.Like all good popular science,it makes a real attempt to expound the details,both of established theories and speculative proposals;rather than just stating the main idea—or worse,just gesturing at it with a metaphor which is liable to be as misleading as it is helpful.(The obvious comparison here is with e.g.Penrose’s The Em-peror’s New Mind,as against Hawking’s A Brief History of Time;or as regards magazines, with e.g.Scientific American,as against New Scientist.)The book contains plenty of detailed exposition—exposition often enlivened by metaphors that are helpful as well as vivid.(Some readers will also enjoy the anecdotes of Barbour’s various intellectual strug-gles,journeyings and collaborations.)Barbour also moderates his passionate advocacy of his ideas,especially his quantum speculations,with occasional reminders that they are controversial.The second reason is that,although cognoscenti will know Barbour’s previous work on Machian themes in classical physics(both relativistic and non-relativistic),it is worth having an accessible exposition in a single book.For in some respects,this work goes against prevailing opinion in the philosophy of space and time;and perhaps for this reason,it is still not very well known.I shall devote Section2to this material.To set the scene,I shallfirst describe prevailing opinion,and a problem it faces.Then in discussing Barbour’s Machian theories,I will emphasise how Barbour takes space rather than spacetime as fundamental,and how this is in tension with relativity.1 The third reason relates to Barbour’s denial of time.Philosophers of physics,and indeed metaphysicians,are bound to want to know what this denial amounts to.Fortu-nately,I can present the main ideas in terms of familiar metaphysical categories,without recourse to quantum theory,let alone quantum gravity.I shall do so in Section3.1;we shall see that it is a curious,but coherent,position which combines aspects of modal realism`a la David Lewis and presentism`a la Arthur Prior.Thenfinally,in Section3.2, I shall discuss how Barbour argues for his denial of time from certain claims about theinterpretation of quantum theory,and about quantum gravity.2But beware:although my strategy of postponing quantum theory and quantum grav-ity,with all their obscurities,until Section3.2makes for an exposition more accessible to philosophers,it also carries a ly,it emphasizes those aspects of Barbour’s denial of time which can be explained in terms of classical physics(i.e.roughly,in terms of instantaneous configurations of matter),in particular Barbour’s idea of a‘time capsule’; and it downplays a technical quantum-theoretic aspect,which Barbour(private commu-nication)sees as prior to,and more important than,time capsules.So I should at the outset summarize this aspect,‘the price’,and say why I think my strategy is justified.Barbour believes that his Machian analysis of general relativity gives the best un-derstanding of(and justification for)the two equations that sum up the theory in the form in which it is most easily quantized.(The equations are called the momentum and the Hamiltonian constraint equations;the form of the theory is called the Hamiltonian, or canonical,form.)Since quantizing general relativity(in this form)by an otherwise successful method leads to a static i.e.time-independent quantum state,Barbour con-cludes that we must accept such a state and somehow reconcile it with the appearance of time and change.He takes this to be his main conclusion:and time capsules to be his admittedly conjectural suggestion for how to make the reconciliation.Nevertheless,there is good reason for me to emphasize time capsules,at the expense of the arguments leading to a static quantum state.For as we shall see in Section3.2,most of these arguments have been well known in the physics literature for many years,and some are even prominent in the growing philosophical literature about quantum gravity. Besides,the literature contains several(mostly very technical)strategies for reconciling a static quantum state with the appearance of time and change.Barbour’s time capsules proposal is but one of these,with the advantage that it can be explained non-technically: so in a review of his work,I have of course chosen to focus on it,ignoring the others.I shallfinish this Introduction with my three main criticisms of the book as a popular-ization.First,the book gives the misleading impression that Barbour’s various views are closely connected one with another.In fact,Barbour’s views are by no means a package-deal.In particular,the straightforward and craftsmanlike work in classical physics and in history of physics can be‘bought’;while the denial of time,and the speculations about quantum theory and quantum gravity,are left on the shelf.The other two criticisms both concern‘the end of time’;thefirst from a metaphysical viewpoint,the second from a physical one.First:Barbour often(not just in the‘prospec-tus’,Part1,but also in Parts4and5)states his denial of time in a way that philosophers will immediately interpret as just denying temporal becoming.This is misleading:his view is different from the familiar tenseless(‘B-theory’)view of time—as we will see in Section3.Second:As I mentioned above,the quantum gravity programme on which Barbour fo-cusses,quantum geometrodynamics,has been superseded.Agreed,it has a distinguished descendant,the loop quantum gravity programme,which is one of the two main currentprogrammes;(the other being the superstrings programme,which is utterly different, not just technically,but also in its motivations and framework).But the central notion of a configuration is very different in loop quantum gravity than in quantum geometro-dynamics;and Barbour has yet to tell us how his proposals,e.g.about time capsules, would carry over to it.Besides,even on its own terms,quantum geometrodynamics is very problematic.In particular,its main equation,the Wheeler-DeWitt equation,is not mathematically well-defined,and its‘derivation’is questionable.Though Barbour briefly mentions the rival programmes,and the quantum geometrodynamics programme’s inter-nal difficulties(at pp.38-39,166,192,351),the bulk of the book is devoted to presenting his Machian vision of exactly this programme.So a reader who is a newcomer to the sub-ject will inevitably get the impression that geometrodynamics is still‘one of the runners’in the race of quantum gravity research.Agreed,that race has no clear running-track or rules:it is rather like orienteering in a blizzard—without a map!So indeed,quantum geometrodynamics just might‘come from the back of thefield to win the race’.But newcomers be warned:it seems unlikely.3These three criticisms aside,the book is,overall,very good popular science:we can happily go along with Barbour when he announces that he has‘tried to write primarily for the general reader...but shall be more than happy if my colleagues look over my shoulder’(p.7).2Machian themes in classical physicsI shallfirst summarize the prevailing opinion in the philosophy of space and time,as three claims;and describe how they face a consistency problem.This problem is not insoluble, nor unrecognized;but it is substantive(Section2.1).This will set the scene for discussing Barbour’s own work(Section2.2).2.1The status quo2.1.1OrthodoxyIn contemporary philosophy of space and time,the prevailing opinion is that the devel-opment of physics from the mid-nineteenth century(especially the rise offield theories culminating in general relativity)was the death-knell of the relationist tradition,stem-ming from Leibniz to Mach,of conceiving space and time as systems of spatiotemporal relations between bodies,rather than entities in their own right.More precisely,there are three prevalent claims which need to be articulated here.I shall list them in what I believe to be the order of increasing controversy!4These claims concern,respectively:(1)field vs.matter,(2)whether metrical structure is‘reducible’to matter,and(3)the status of spacetime points.(1)Thefirst claim concerns the rise offield theory since1850.Thus,on the one hand,physics revealed some traditional characteristics of bodies—such as impenetrability and continuity—to be only apparent.And on the other hand,the electromagneticfield was discovered to possess mechanical properties like momentum,angular momentum, energy and(after the advent of special relativity)mass-energy.Besides,matter itself was eventually modelled,with outstanding success,as afield on spacetime;namely in quantumfield theories.Thus Leibniz’s and Mach’s‘bodies’had become diaphanous and omnipresentfields.(2)Second,the various familiar theories—both classical and quantum,relativistic and non-relativistic—postulate a metrical structure of spacetime that seems not to be ‘reducible to spatiotemporal relations of bodies’(in various precise senses of that phrase). Two well known(probably the best known)ways of making this claim precise concern: (a)absolute rotation,and(b)dynamical metrics.For(a),the idea of the argument goes back to Newton’s globes thought-experiment. The two cases—one in which the mutually stationary globes rotate at some constant ve-locity about their common centre of gravity,and the other with no rotation—are intended to show that the metric is irreducible;the idea is that the two cases exhibit the same spa-tiotemporal relations of bodies but different metrical facts.But one needs to be careful about‘metrical facts’.For in any theory,such as Newtonian mechanics or special relativ-ity,in which the metric structure is the‘same in all models’(and so is not dynamical,i.e. not correlated with the distribution of matter),there will be a sense of‘metrical facts’in which these facts cannot differ between two models—and so are trivially determined by, i.e.supervenient upon,spatiotemporal relations between bodies.(Compare the idea in modal metaphysics that a proposition M true in all of a certain class of worlds trivially supervenes on the truth of any proposition S true at some of the worlds:for any two worlds in the class that make S true,also make M true.)There is an obvious strategy for otherwise interpreting‘metrical facts’in such a way that pairs of cases like the two globes nevertheless show some kind of irreducibility of the metric.The idea is that such a pair of cases shows that not all physical possibilities are distinguished by a full description of each of them in terms of the masses,relative distances and relative velocities of bodies;so that there are physically real properties or relations not determined by these.What these are will differ from one proposal to another.But irreducibility will follow,provided the‘metrical facts’include some of the facts involving such undetermined properties or relations.Here the obvious candidate is facts about how the bodies are related to the affine structure of spacetime—in short,about whether their worldlines are geodesics.5As to(b):For a theory with a dynamical metric such as general relativity(or any theory that‘geometrizes gravity’in the sense of coding gravitational force as an aspect of the metric),the above problem of‘metrical facts’being‘the same in all models’,and so trivially determined by the matter distribution,does not arise.Nor is the correlation (or even causal relation)between the metric and the matter distribution,as coded in the field equations,a sign of reduction or even determination(i.e.supervenience).First,we cannot in general specify the matter distribution without the metric.Second,general relativity admits pairs of solutions which agree on their matter distributions but differ metrically.For general relativity,the most-cited cases are the various vacuum(i.e.matter fields zero)solutions.But there are other examples,e.g.the Schwarzschild and Kerr metrics—representing respectively,a non-rotating and a rotating mass in an otherwise empty universe.6(3)Third,the formalisms offield theories,both classical and quantum,suggest that their basic objects are just spacetime points.For in these formalisms,everything apart from these points—matter,whether conceived as point-particles or asfields,and even the metrical structure of spacetime—gets represented as mathematical structures defined on points.This suggests the doctrine nowadays called‘substantivalism’:that spacetime points are genuine objects—indeed are the basic objects of these theories,in that ev-erything else is to be construed as properties of points,or relations between them,or higher-order properties and relations defined over them.Agreed,this doctrine is controversial even among those with no sympathy for rela-tionism.There are two well-known good(though disputable!)reasons for denying it.(a): Thefirst reason is‘the hole argument’.It is natural to formulate these theories,especially those with a dynamical metric(like general relativity),in such a way that their only‘fixed structure’is the local topological and differential structure of a manifold.Intuitively,this means that any map preserving this structure(i.e.any diffeomorphism)preserves the content of the theory.Such a theory is called‘diffeomorphism invariant’;and diffeomor-phism invariance is often taken to indicate that spacetime points are indeed not objects: their appearing to be is an artefact of how we formulate the theory.(b):The second reason is a general philosophical point about objects or ly:we should be wary of taking as the basic objects of our ontology(according to some theory)those items that are postulated as the initial elements in a mathematical presentation of the theory. For it might be just a happenstance of our formulation of the theory that these objects‘comefirst’:a happenstance avoided by another formulation that can be agreed,or at least argued,to be better.2.1.2The consistency problemThese three claims lead to what I will call‘the consistency problem’.This is not a straightforward matter of the claims entailing the problem.Rather,these claims,and the presentations of spacetime theories that are now typical,both in physics textbooks and the philosophy of physics literature,make us think of the metrical structure of spacetime in a certain way—roughly,as‘on all fours’with the matterfields.7And it is this conception that leads to the consistency problem.As I said at the start of the Section,I do not claim that this problem is insoluble:rather it is a lacuna that needs to befilled.Nor is the problem unrecognized:as we will see,Einstein himself recognized it(and dubbed it a problem of‘consistency’).Furthermore,we can nowadays state in broad terms how the problem can be solved(the lacunafilled).But the problem is worth stressing,since it is rarely addressed—and it leads into Barbour’s Machian proposals.I shall present the problem byfirst describing the lacuna in typical modern presen-tations of spacetime theories.In such presentations,one postulatesfirst a spacetime manifold;then,some metric(and affine)structure on it,typically as metricfields;then also some matterfields;thesefields,both metric and matter,obey differential equations; etc.So far,so good.Indeed,so far,so pure mathematical.The connection with observa-tion is then made,for metricfields,by postulating that(ideal)rods and clocks measure the metric,i.e.yield its values as their pointer-readings.Or maybe the connection is made more generally than via the proverbial rods and clocks—by postulating that the be-haviour(perhaps ideal)of matterfields gives us access,in principle,to the metricfields. But—here is the rub—there is,typically,little or no discussion of how the rods and clocks are constructed and how they‘do their stuff’—display pointer-readings that are veridical about spacetime’s metric.(Similarly,for more general accounts of how matter gives access to metric.)If one does not notice this lacuna8,one naturally ignores the question of how indeed they do their stuff;and so falls into thinking of the metric as simply‘read off’by rods and clocks.But of course it is a question that cannot be ignored.In any branch of physics,one has a right to expect a theory of how the instrument works(very often calling on otherbranches of physics,on which the instrument’s functioning depends).In this regard rods and clocks(or whatever else,such as radar signals,is postulated as measuring the metric) are no different from other instruments.An account thatfilled this lacuna would proceed:from(i)the postulation of funda-mental metric and matterfields on spacetime;to(ii)a theoretical description of how(at least idealized)rods and clocks(or whatever else)behave,powerful and accurate enough to secure that:(iii)such rods and clocks(or other matter)would indeed do their stuff—their pointer-readings report the metric.There are four remarks to make about such an account.Broadly speaking,they are positive:there are good prospects for such an account,though the details would of course be very complicated.(Or rather,there are good prospects if we set aside the usual deep controversies about how the macroscopic world emerges from the quantum one.)•The way that(iii)returns to(i)is in no way a suspicious circularity.An account of how things are should be compatible with the explanation how we come to know or believe that very account;and it is even better if the account coheres with,or even is itself a part of,that explanation.•As I mentioned,Einstein himself emphasised the need for such an account,and called the lacuna a problem of‘consistency’.In his Autobiographical Notes,he writes in connection with special relativity:One is struck[by the fact]that the theory introduces two kinds of physicalthings,i.e.(1)measuring rods and clocks,(2)all other things,e.g.theelectro-magneticfield,the material point,etc.This in a certain senseis inconsistent;strictly speaking,measuring rods and clocks would haveto be represented as solutions of the basic equations(objects consistingof moving atomic configurations),not,as it were,as theoretically self-sufficient entities.However,the procedure justifies itself because it wasclear from the very beginning that the postulates of the theory are notstrong enough to deduce from them sufficiently complete equations forphysical events sufficiently free from arbitariness,in order to base uponsuch a foundation a theory of measuring rods and clocks...it was better topermit such inconsistency—with the obligation,however,of eliminating itat a later stage of the theory.But one must not legalize the mentioned sinso far as to imagine that intervals are physical entities of a special type,intrinsically different from other physical variables(“reducing physics togeometry”,etc.).([1949],pp.59-60.)•So the consistency problem is recognized.Indeed,some expositions of relativity, less imbued with the geometric style of presentation,sketch such an account of rods and clocks:trying to discharge,in Einstein’s phrase,the obligation of eliminating the inconsistency.I say‘sketch’because it is very hard to describe,in terms of one’s fundamental physical theory,most types of clock(and most types of any other instrument):Einstein notes this for special relativity,but the point is ofcourse equally valid for other theories,such as continuum mechanics in Newtonian spacetime.As a result,the expositions that sketch such an account often focus on some artificially simple models;e.g.the light-clock,or(as a model of length-contraction)the distortion in a classical atom of the electron’s orbit,due to the atom’s motion;cf.Bell[1976].9•Besides,we have good reason to think we can go beyond such simple models,and in particular accommodate the quantum nature of matter.To take one example,let me sketch a quantum description of length-contraction for a moving rod.(Many thanks to David Wallace for this sketch.)I suppose that we start with some quantum field theory of electrons,the electromagneticfield,and a chargedfield of much higher charge and mass than the electronfield(to simulate atomic nuclei of some particular element).This is a reasonable place to start,because:(i)we certainly need to go beyond classical physics since it cannot describe solid bodies other than phenomenologically(e.g.stipulating a priori that rods are rigid);(ii)on the other hand,to require that we start with the Standard Model and work our way up through quark-quark couplings etc.would be unduly harsh—since after all,we don’t believe it provides thefinal theory of matter.We then need to establish that there are certain states of this multi-field system describing a non-relativistic regime of particles coupled by effective Coulomb forces, with respect to a3+1split given by some Lorentz frame;and that in this regime, there are states corresponding to rigid non-relativistic matter,say a crystal.Suppose we succeed in this.Of course this is conceptually and technically difficult,given the interpretative problems of quantumfield theory,and the complexities of solid state physics.But given that there are such states,we can argue that a rod made of this crystalline matter will exhibit length contraction;as follows.If the rod is accelerated gently enough,the internal vibrations(phonons)due to the acceleration will be small and will rapidly thermalise(heating the crystal up slightly until the heat is lost to the environment),and the crystal will enter the stateˆB|ψ ; whereˆB is the Galilean boost operator for thefinal velocity attained,and|ψ is the original state of the rod i.e.the state of a rigid crystal with length(say)l given by the metric in our initial frame.The fact that sufficiently small Lorentz boosts can be approximated by Galilean boosts then implies that we can iterate boosts to move|ψ into the stateˆB L|ψ ,where stateˆB L is any Lorentz boost.Since the underlying quantum-field-theoretic dynamical laws are Lorentz-covariant,it follows thatˆB L|ψ has length l as given by the metric in the boosted frame.So we have established that the crystal accurately measures the metric in its rest frame, i.e.length contraction.(Or more accurately,we would have established this if our sketch werefilled in!).To sum up:though one faces a consistency problem if one postulates a metric‘on allfours’with matterfields,our current theories of matter seem able to solve the problem, at least in outline.2.2MachianismIn this subsection,I willfirst make two general points about Barbour’s variety of Machi-anism,and discuss his attitude to Section2.1.1’s three claims(1)to(3)(Section2.2.1). This will lead to some details of his Machian theories(Section2.2.2).I will end with some evaluative comments about these proposals,especially the central ingredient of the Machian theories—the notion of an instantaneous configuration(Section2.2.3).2.2.1The temporal metric as emergentOne naturally expects that ceteris paribus,the consistency problem will be easier to solve, the weaker the metrical structure of spacetime that one postulates‘on all fours’with matterfields:for there will be less structure that,for consistency,instruments’pointer-readings have to‘reveal’.On the other hand,one needs to postulate enough structure to be able to write down a dynamical theory:one cannot expect all such structure to be reducible to matter(cf.(2)of Section2.1.1).So the question arises whether there are interesting dynamical theories that postulate less metrical structure than the familiar theories.Barbour’s work shows that the answer is‘Yes’.There are two immediate points to make about this‘Yes’.First,in the theories Bar-bour has developed so far,the gain mostly concerns the temporal aspect of the spacetime metric:though the temporal metric‘emerges’from the rest of physics,the spatial metric is still postulated.10Second,a point about the notion of‘emergence’.Usually,this notion is vague:and philosophers think of making it more precise in terms of various definitions of reduction, or some weaker analogue,such as supervenience.It will turn out that in the context of Barbour’s views,two more precise versions play a role,one for the classical context (this Section),and one for the context of quantum gravity(Section3).In the classical context,Barbour’s notion is logically strong,indeed surprisingly so.For Barbour provides examples of theories in which a temporal(though not spatial)metric is emergent in the strong sense of being fully definable from the rest of the physical theory.So this is emergence in as strong a sense of reduction as you might want.On the other hand,in the context of quantum gravity,Barbour’s notion is logically weak(though again the detail is surprising).For his denial that there is time leads to his saying that our illusion to the contrary—that there is time—is a partial and misleading‘appearance’of the timeless underlying reality.I turn to discussing Barbour’s attitude to Section2.1.1’s claims,(1)to(3),of‘pre-vailing opinion’;in particular to justifying my statement(in footnote4)that he agrees to(1)and(2),and maybe also(3).Since claim(2),about the irreducibility of metric to matter,concerns‘the various familiar theories’,it is already clear that he can accept it while nevertheless seeking theories in which there is some kind of reducibility.The kind of theory he seeks emerges more clearly from his replies to(1)and(3).As to the claim(1),Barbour accepts that physics since1850has‘abolished body’.But he takes this to mean just that we should state Machian proposals in terms of the modern conception of matter,namely as matterfields.So although Barbour presents Machian theories of point-particles(pp.71-86,115-120;and similarly in his technical articles), that is intended as a piece of pedagogy and/or heuristics—a path I will follow in Section 2.2.2.As he stresses,the main physical ideas of these theories carry over tofield theories.This of course prompts the question:how exactly does Barbour conceivefield theories? In particular,does he accept the existence of spacetime points,as advocated by claim(3)? It will be clearest to break the answer to these questions into two parts.Thefirst part concerns Barbour’s different attitudes to spacetime,and to space:this part relates closely to the physical details of his proposals,and will engender several comments.The second part concerns Barbour’s relationist understanding of space;it is more philosophical,and will crop up again later—at this stage,it can be dealt with briefly.Thefirst part of the answer is,in short,that Barbour seems happy to accept the existence of spatial(but not spacetime)points,and to postulate that these points form a3-dimensional manifold with metric(spatial geometry).For he discussesfield theories (relativistic and non-relativistic)in terms of the evolution through time of instantaneous 3-dimensional configurations,i.e.states of a3-dimensional spatial manifold.But one needs to be careful;(and here lies the second part of the answer).Since Barbour seeks a relationist understanding of space,he wants to treat metrical relations in afield theory, not in terms of a metricfield tensor on a3-manifold of spatial points,but as very similar to inter-particle distances in theories of point-particles.This kind of treatment will become clearer in Section2.2.2.2.Here it suffices to say two things.(i)The main idea is that, just as a Machian theory of N point-particles will treat metrical relations as essentially a matter of N(N−1)/2inter-particle distances,a Machianfield theory will postulate point-like parts of a matterfield and then treat metrical relations in terms of the continuous infinity of all the pairwise distances between these point-like parts.(ii)As we shall see in a moment(and again in Sections2.2.2.2and2.2.3),this sort of Machian treatment of field theories has difficulties with general relativity.Thefirst part of the answer—that Barbour postulates space,and spatial geometry, but is leary of spacetime—also needs to be clarified in other ways.Indeed,it holds good for his discussion of both classical non-relativisticfield theories,and quantum theories. By his lights,spacetime notions have no central role in either of these types of theory.But his reasons are rather different for the two types(as I hinted above,in discussing strong and weak emergence).For classical non-relativisticfield theories,the temporal structure (and so spacetime structure)is fully defined,in Barbour’s Machian theories,by the rest of the theory:but(modulo the attempt to understand space relationally)these theories。
