Can we make progress exploring consciousness? Or is it forever beyond human reach? In science we never know the ultimate outcome of the journey. We can only take whatever steps our current knowledge affords. This paper explores today's evidence from the viewpoint of Global Workspace theory. First, we ask what kind of evidence has the most direct bearing on the question. The answer given here is ‘contrastive analysis’ -- a set of paired comparisons between similar conscious and unconscious processes. This (...) body of evidence is already quite large, and constrains any possible theory . Because it involves both conscious and unconscious events, it deals directly with our own subjective experience, as anyone can tell by trying the demonstrations in this article. (shrink)

Bernard Williams's remarkable essay on morality confronts the problems of writing moral philosophy, and offers a stimulating alternative to more systematic accounts which seem nevertheless to have left all the important issues somewhere off the page. Williams explains, analyses and distinguishes a number of key positions, from the purely amoral to notions of subjective or relative morality, testing their coherence before going on to explore the nature of 'goodness' in relation to responsibilities and choice, roles, standards, and human nature. (...) The final chapters make a fascinating enquiry into what morality is about, looking beyond happiness to other human aims and ideals. This re-issue of a classic in moral philosophy includes a new foreword by the author. (shrink)

Philosophy should not try to assimilate itself to the aims of the sciences. Scientism stems from the false assumption that a representation of the world minimally based on local perspectives is what best serves self-understanding. Philosophy must concern itself with the history of our conceptions, and we must overcome the need to think that this history should ideally be vindicatory. There is no basic conflict between arguing within the framework of our ideas, reflectively making better sense of them, and understanding (...) their highly contingent history. The third of these activities is an inescapable part of the second. (shrink)

Ethical aspects of management control systems are attracting increasing attention among scholars and practitioners. Much of the work centers on their aims. We complement this scholarship by applying the ethical principle of “no harm,” i.e., non-maleficence, to examine how those aims are achieved. We illustrate this approach by exploring the effects of four MCS designs on job-related stress drawing on the differentiation of stress into two dimensions: a challenge and a threat dimension. Results from a lagged field-survey with 471 managers (...) and employees from the UK and the U.S. support key predictions and offer first insights into designing MCS based on a “no harm” ethics. Our study highlights the benefits of interdisciplinary research in business ethics and hopefully encourages more work on MCS from a perspective based on the non-maleficence principle. (shrink)

The author, seeing science as a social activity, directs our attention to the problems of the social control of science. He discusses the sense in which science as a social activity is planned and unplanned.

An old question, still much discussed in moral philosophy, is whether there is any ethical knowledge. It is closely related, by simple etymology, to the question of cognitivism in ethics. Despite the fact that the terms ‘cognitivism’ and ‘objectivism’ seem sometimes to be used interchangeably, I take it that the question whether there can be ethical knowledge is not the same as the question whether ethical outlooks can be objective. A sufficient reason for this is that an ethical outlook might (...) be taken to consist of rules or principles, which do not admit of truth or falsehood and so cannot be objects of knowledge, but which can be seen as having an objective basis.

The justification of Bayes' rule by cognitive rationality principles is undertaken by extending the propositional axiom systems usually proposed in two contexts of belief change: revising and updating. Probabilistic belief change axioms are introduced, either by direct transcription of the set-theoretic ones, or in a stronger way but nevertheless in the spirit of the underlying propositional principles. Weak revising axioms are shown to be satisfied by a General Conditioning rule, extending Bayes' rule but also compatible with others, and weak updating (...) axioms by a General Imaging rule, extending Lewis' rule. Strong axioms (equivalent to the Miller–Popper axiom system) are necessary to justify Bayes' rule in a revising context, and justify in fact an extended Bayes' rule which applies, even if the message has zero probability.

Moral status is a vexing topic. Linked for so long to the unending debates about ensoulment and the morality of abortion, it has recently resurfaced in the embryonic stem cell controversy. In this new context, it should benefit from new insights originating in recent scientific advances. We believe that the recently observed capability of somatic cells to return to a pluripotential state (a capability we propose to name 'reversed potency') in a controlled manner requires us to modify the traditional concept (...) of moral status and to consider it as referring not only to intrinsic properties (like 'to possess reason' or 'to be a person'), but also to extrinsic or relational ones.

The scholastic philosopher is interested in definition for a different reason than the lexicographer and linguist. The philosopher is trying to learn things. Fe defines, after investigating reality, in an attempt to describe reality clearly and to sum up some aspect of his understanding of reality. Hence, we find our scholastic philosophers adopting as a main feature of their method this insistence on defining, on precise and detailed explanation of their definitions, and on proving that their definitions da correctly express (...) what a nature or activity is. A dictionary of the language of scholastic philosophy fitted to the needs of beginners and of undergraduate students of the subject is not available in English. (shrink)

I outline some of my work and results on my matter-gravity entanglement hypothesis, according to which the entropy of a closed quantum gravitational system is equal to the system’s matter-gravity entanglement entropy. The main arguments presented are: that this hypothesis is capable of resolving what I call the second-law puzzle, i.e. the puzzle as to how the entropy increase of a closed system can be reconciled with the asssumption of unitary time-evolution; that the black hole information loss puzzle may be (...) regarded as a special case of this second law puzzle and that therefore the same resolution applies to it; that the black hole thermal atmosphere puzzle can be resolved by adopting a radically different-from-usual description of quantum black hole equilibrium states, according to which they are total pure states, entangled between matter and gravity in such a way that the partial states of matter and gravity are each approximately thermal equilibrium states ; that the Susskind–Horowitz–Polchinski string-theoretic understanding of black hole entropy as the logarithm of the degeneracy of a long string cannot be quite correct but should be replaced by a modified understanding according to which it is the entanglement entropy between a long string and its stringy atmosphere, when in a total pure equilibrium state in a suitable box, which ) goes over, at strong-coupling, to a black hole in equilibrium with its thermal atmosphere. The modified understanding in is based on a general result, which I also describe, which concerns the likely state of a quantum system when it is weakly coupled to an energy-bath and the total state is a random pure state with a given energy. This result generalizes Goldstein et al.’s ‘canonical typicality’ result to systems which are not necessarily small. (shrink)

It has long been believed that if man had a special function appropriate to him, and that if we could discover what it was, then we would be in a perfect position to solve all of the basic problems of ethics. For if we were, for example, shovels, and knew ourselves to be shovels, then we would also know that to spend our lives in digging would best serve our fundamental interests, realize our highest aspirations, and be in every respect (...) the correct thing to do. Or so the theory goes; a theory which is shared, interestingly enough, by Aristotle and Sartre, even though they share little else, and even though one of them believes that man has a function and the other does not.

Abduction was first introduced in the epistemological context of scientific discovery. It was more recently analyzed in artificial intelligence, especially with respect to diagnosis analysis or ordinary reasoning. These two fields share a common view of abduction as a general process of hypotheses formation. More precisely, abduction is conceived as a kind of reverse explanation where a hypothesis H can be abduced from events E if H is a good explanation of E. The paper surveys four known schemes for abduction (...) that can be used in both fields. Its first contribution is a taxonomy of these schemes according to a common semantic framework based on belief revision. Its second contribution is to produce, for each non-trivial scheme, a representation theorem linking its semantic framework to a set of postulates. Its third contribution is to present semantic and axiomatic arguments in favor of one of these schemes, ordered abduction, which has never been vindicated in the literature. (shrink)

Despite its importance in various fields, analogical reasoning has not yet received a unified formal representation. Our contribution proposes a general scheme of inference that is compatible with different types of logic (deductive, probabilistic, non-monotonic). Firstly, analogical assessment precisely defines the similarity of two objects according to their properties, in a relative rather than absolute way. Secondly, analogical inference transfers a new property from one object to a similar one, thanks to an over-hypothesis linking two sets of properties. The belief (...) strength in the conclusion is then directly related to the belief strength in this meta-hypothesis. (shrink)
