This paper presents a new derivation of the inequalities from non-trivial non-local theories and formulates a stronger Bell argument excluding also these non-local theories. Taking into account all possible theories, the conclusion of this stronger argument provably is the strongest possible consequence from the violation of Bell inequalities on a qualitative probabilistic level (given usual background assumptions). Among the forbidden theories is a subset of outcome dependent theories showing that outcome dependence is not sufficient for explaining a violation of Bell inequalities. Non-local theories which can violate Bell inequalities (among them quantum theory) are rather characterized by the fact that at least one of the measurement outcomes in some sense (which is made precise) probabilistically depends both on its local as well as on its distant measurement setting (‘parameter’). When Bell inequalities are found to be violated, the true choice is not ‘outcome dependence or parameter dependence’ but between two kinds of parameter dependences, one of them being what is usually called ‘parameter dependence’. Against the received view established by Jarrett and Shimony that on a probabilistic level quantum non-locality amounts to outcome dependence, this result confirms and makes precise Maudlin’s claim that some kind of parameter dependence is required.</p></div>","PeriodicalId":54442,"journal":{"name":"Studies in History and Philosophy of Modern Physics","volume":"72 ","pages":"Pages 1-28"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.shpsb.2017.03.002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41735999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper attempts to complement these debates by studying the spin-2 approach to (quantum) gravity. In particular, the paper argues that three lessons can be drawn from the spin-2 approach: (1) different from what is sometimes claimed in the literature, central aspects of the non-linear theory of GR are already derivable in classical spin-2 theory; in particular, ‘universal coupling’ can be considered a derived ‘theorem’ in both the classical and the quantum spin-2 approach; this provides new insights for the investigation of the equivalence principle; (2) the ‘second miracle’ that Read et al. argue characterises GR is explained in the classical as well as in the quantum version of the spin-2 approach; (3) the spin-2 approach allows for an ontological reduction of the metrical part of spacetime to the dynamics of matter fields.</p></div>","PeriodicalId":54442,"journal":{"name":"Studies in History and Philosophy of Modern Physics","volume":"72 ","pages":"Pages 29-45"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.shpsb.2020.05.002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48701539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Newton's early metaphysics of body: Impenetrability, action at a distance, and essential gravity 牛顿早期的身体形而上学：不可穿透性、远距离作用和本质引力

Howard Stein has argued that such a conception privileges contact over distant action: by dint of being impenetrable, bodies must necessarily act through contact; yet there is no analogous property of which action at a distance is a consequence. This paper presents a challenge to Stein's reading. I begin by arguing that impenetrability cannot imply action through contact because such an implication hinges on one's laws of motion in three senses: it must be physically possible for contact to occur, the laws must make coherent the notion of a trajectory from which a body deviates, and the necessity of introducing collision dynamics renders impenetrability otiose. I then turn to a close reading of De gravitatione and consider whether Newton himself sees his account of body as establishing contact action as prior to distant action in any sense. Although Newton did see impenetrability as rendering bodily action intelligible, ample room remains for action at a distance once one takes into account certain textual ambiguities and the provisional character of the narrative. By way of substantiating this reading and answering an objection of Stein's, I pivot to Newton's remarks concerning the nature of gravity in his correspondence with Bentley. Although Newton is often held to reject essential gravity as being in conflict with his metaphysical commitments, I offer a more austere reading on which Newton is decrying a kind of action that is unmediated, or alleged to take place without a cause. By contrast, Newton carves out a place for action at a distance mediated by an immaterial agent as a perfectly acceptable explanation of natural phenomena.</p></div>","PeriodicalId":54442,"journal":{"name":"Studies in History and Philosophy of Modern Physics","volume":"72 ","pages":"Pages 192-204"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.shpsb.2020.06.003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44663499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
