A computational theory of consciousness should include a quantitative measure of consciousness, or MoC, that (i) would reveal to what extent a given system is conscious, (ii) would make it possible to compare not only different systems, but also the same system at different times, and (iii) would be graded, because so is consciousness. However, unless its design is properly constrained, such an MoC gives rise to what we call the boundary problem: an MoC that labels a system as conscious (...) will do so for some – perhaps most – of its subsystems, as well as for irrelevantly extended systems (e.g., the original system augmented with physical appendages that contribute nothing to the properties supposedly supporting consciousness), and for aggregates of individually conscious systems (e.g., groups of people). This problem suggests that the properties that are being measured are epiphenomenal to consciousness, or else it implies a bizarre proliferation of minds. We propose that a solution to the boundary problem can be found by identifying properties that are intrinsic or systemic: properties that clearly differentiate between systems whose existence is a matter of fact, as opposed to those whose existence is a matter of interpretation (in the eye of the beholder). We argue that if a putative MoC can be shown to be systemic, this ipso facto resolves any associated boundary issues. As test cases, we analyze two recent theories of consciousness in light of our definitions: the Integrated Information Theory and the Geometric Theory of consciousness. (shrink)

A recently proposed model of sensory processing suggests that perceptual experience is updated in discrete steps. We show that the data advanced to support discrete perception are in fact compatible with a continuous account of perception. Physiological and psychophysical constraints, moreover, as well as our awake-primate imaging data, imply that human neuronal networks cannot support discrete updates of perceptual content at the maximal update rates consistent with phenomenology. A more comprehensive approach to understanding the physiology of perception (and experience at (...) large) is therefore called for, and we briefly outline our take on the problem. (shrink)

The striving for a more equal society has been an inspiring ideal for social policy and a powerful engine for the foundations of the welfare state. However, equality as a political concept has been subject to ongoing criticism and has been gradually denounced. In an attempt to reclaim the appeal of economic equality, this paper endeavors to cross the common boundaries of redistribution and to offer a different equalizing strategy titled "Levelling Down". This strategy has been extensively debated in political (...) philosophy but has not been examined through a social policy perspective. This gap is addressed in the following discussion which aims to generate achievable policy implications with greater commitment to the ideal of equality. (shrink)

This paper proposes a way to understand transformative choices, choices that change ‘who you are.’ First, it distinguishes two broad models of transformative choice: 1) ‘event-based’ transformative choices in which some event—perhaps an experience—downstream from a choice transforms you, and 2) ‘choice-based’ transformative choices in which the choice itself—and not something downstream from the choice—transforms you. Transformative choices are of interest primarily because they purport to pose a challenge to standard approaches to rational choice. An examination of the event-based transformative (...) choices of L. A. Paul and Edna Ullman-Margalit, however, suggests that event-based transformative choices don’t raise any difficulties for standard approaches to rational choice. An account of choice-based transformative choices—and what it is to be transformed—is then proposed. Transformative choices so understood not only capture paradigmatic cases of transformative choice but also point the way to a different way of thinking about rational choice and agency. (shrink)

Don Marquis’ future-like-ours account argues that abortion is seriously immoral because itdeprives the embryo or fetus of a valuable future much like our own. Marquis was mindful ofcontraception being reductio ad absurdum of his reasoning, and argued that prior tofertilisation, there is not an identifiable subject of harm. Contra Marquis, Tomer Chaffercontends that the ovum is a plausible subject of harm, and therefore contraception deprives theovum of a future-like-ours. In response, I argue that being an identifiable subject of harm (...) is notsufficient for Marquis’ argument to succeed. In addition, we must also share our identity withan ovum. I show that on the account of personal identity utilised by Marquis’ defenders, weare not identical with an ovum. As a result, Chaffer’s reductio fails. (shrink)

This article addresses the emergence of African– European business relationships. Its focus is on the role of bargaining power and information tech- nology and its impact on the different stakeholders in (electronic) markets (sellers, market maker, buy- ers). Information technology is seen as an enabling technology that facilitates reaching a wider cus- tomer base (called reach) and providing a channel for increased customer services (called richness). The central question is how African suppliers can create bargaining power by means of (...) information technology and therefore enter and improve their position in European markets. Research is carried out in the flower industry. In this industry African flower growers create competitive advantage and develop business relationships with European buy- ers (wholesalers, retailers). In this article we inves- tigate three flower markets (Tele Flower Auction, FloraHolland Auction, and Aalsmeer Auction), the role of African flower growers, and the use and impact of information technology in these markets. The results of our research show that there are pot- entials for African flower growers to enter the Euro- pean flower markets and to increase their position of bargaining power. A first potential is using and implementing information technology for the access to new and large European markets. African flower growers use information technology to streamline transaction processes and lower transac- tion costs. A second potential is related to the qual- ity and specificity of the produced flower products. Information technology can remove the quality uncertainty of products and can provide rich infor- mation services to buyers. The results in the flower industry suggest that information technology pro- vides opportunities for the African producers to expand the reach and richness of their product and service offerings, thus creating economic value.
