Can Physics ever be Complete if there is no Fundamental Level in Nature?

In their recent book Every Thing Must Go, Ladyman and Ross claim: (i) Physics is analytically complete since it is the only science that cannot be left incomplete. (ii) There might not be an ontologically fundamental level. (iii) We should not admit anything into our ontology unless it has explanatory and predictive utility. In this discussion note I aim to show that the ontological commitment in implies that the completeness of no science can be achieved where no fundamental level exists. Therefore, if claim requires a science to actually be complete in order to be considered as physics,, and if Ladyman and Ross's “tentative metaphysical hypothesis ... that there is no fundamental level” is true,, then there simply is no physics. Ladyman and Ross can, however, avoid this unwanted result if they merely require physics to ever strive for completeness rather than to already be complete

Ernst Mach on the Self

In his Contributions to the Analysis of the Sensations (Mach 1885) the phenomenalist philosopher Ernst Mach confronts us with a difficulty: “If we regard the Ego as a real unity, we become involved in the following dilemma: either we must set over against the Ego a world of unknowable entities […] or we must regard the whole world, the Egos of other people included, as comprised in our own Ego.” (Mach 1885: 21) In other words, if we start from a phenomenalist viewpoint, i.e., if we believe that the manifold of sensations we are confronted with is ontologically fundamental —as Mach clearly does: “For us, colors, sounds, spaces, times,… are the ultimate ele-ments” (Mach 1885: 23)—then we are in danger to end up in solipsism. Unless, that is, we assume that some underlying thing-in-itself substratum from which matter, we ourselves, and all the others emanate. The only other alter-native seems to be—and Mach advertises it vehemently for he denies any “mons-trous notion of a thing-in-itself” (Mach 1885: 6)1—that we get rid of the Ego. For, if there is no Self in the first place, then the question whether there are others dissolves. To put it the other way round, it is ok that the others do not exist because, really, I do not exist either. If the Ego is a Myth solipsism is not just wrong but nonsense. There are two questions this paper wishes to address: first, do we need independent additional support for the denial of the Self or is the avoidance of solipsism reason enough to assume the Ego’s non-existence? I will argue that we do need additional reasons and I will evaluate those that Mach indeed gives to prove that “the primary fact is not the I, the Ego, but the elements (sensations)” (Mach 1885: 19). Second, is the deconstruction of the I, even if further sufficient support can be found, really adequate to stop us from worrying about solipsism? The doubt I will put forward is that the illusion of a Self might conjure up enough of an Ego—just like feeling a pain is having a pain, even if it is located in a phantom limb—to start us wondering whether it also occurs elsewhere

The CMEA system of trade and payments : the legacy and the aftermath of its termination

This paper describes the Council for Mutual Economic Assistance (CMEA) system of trade and payment (the"CMEA regime") and considers how the transition from traditional socialism to a market economy is linked to changes in the mechanism for international transactions. The paper begins with a brief history of the CMEA and a description of its organizational structure, institutional principles, and reform efforts. It then provides a brief statistical overview of the relative importance of CMEA trade to its members. The paper sets out the traditional"institutional model"of the CMEA regime, discusses its defects, and briefly evaluates the CMEA regime. After a description of the events surrounding the CMEA's demise in 1990, the paper concludes with the author's conjectures about the consequences of that demise.Environmental Economics&Policies,Economic Theory&Research,TF054105-DONOR FUNDED OPERATION ADMINISTRATION FEE INCOME AND EXPENSE ACCOUNT,Trade Policy,Markets and Market Access

O-Band Differential Phase-Shift Quantum Key Distribution in 52-Channel C/L-Band Loaded Passive Optical Network

A cost-effective QKD transmitter is evaluated in a 16km reach, 2:16-split PON and yields 5.10-7secure bits/pulse. Co-existence with 20 down-and 1 upstream channel is possible at low QBER degradation of 0.93% and 1.1%

Hominin palaeoecology in Late Pliocene Malawi : first insights from isotopes (13C, 18O) in mammal teeth

Carbon-13 and oxygen-18 abundances were measured in large mammal skeletal remains (tooth enamel, dentine and bone) from the Chiwondo Beds in Malawi, which were dated by biostratigraphic correlation to ca. 2.5 million years ago. The biologic isotopic patterns, in particular the difference in carbon-13 abundances between grazers and browsers and the difference in oxygen-18 abundances between semi-aquatic and terrestrial herbivores, were preserved in enamel, but not in dentine and bone. The isotopic results obtained from the skeletal remains from the Chiwondo Beds indicate a dominance of savannah habitats with some trees and shrubs. This environment was more arid than the contemporaneous Ndolanya Beds in Tanzania. The present study confirms that robust australopithecines were able to live in relatively arid environments and were not confined to more mesic environments elsewhere in southern Africa
