This article presents an overview ofregulations, guidelines and societal debates ineight member states of the EC about a)embryonic and fetal tissue transplantation(EFTT), and b) the use of human embryonic stemcells (hES cells) for research into celltherapy, including `therapeutic' cloning. Thereappears to be a broad acceptance of EFTT inthese countries. In most countries guidance hasbeen developed. There is a `strong' consensusabout some of the central conditions for `goodclinical practice' regarding EFTT.International differences concern, amongstothers, some of the informed consent issuesinvolved, and the (...) questions whether anintermediary organisation is necessary, whetherthe methods of abortion may be influenced bythe possible use of EFT, and whether EFTTshould only be used for the experimentaltreatment of rare disorders. The potential useof hES cells for research into cell therapy hasgiven a new impetus to the debate about (human)embryo research. The therapeutic prospects withregard to the retrieval and research use of hEScells appear to function as a catalyst for theintroduction of less restrictive regulationsconcerning research with spare embryos, atleast in some European countries. It remains tobe seen whether the prospect of treatingpatients suffering from serious disorders withtransplants produced by therapeutic cloningwill decrease the societal and moral resistanceto allowing the generation of embryos for`instrumental' use.

In the debate between simple inference heuristics and complex decision mechanisms, we take a position squarely in the middle. A decision making process that extends to both naturalistic and novel settings should extend beyond the confines of this debate; both simple heuristics and complex mechanisms are cognitive skills adapted to and appropriate for some circumstances but not for others. Rather than ask `Which skill is better?'' it is often more important to ask `When is a skill justified?'' The selection and (...) application of an appropriate cognitive skill for a particular problem has both costs and benefits, and therefore requires the resolution of a tradeoff. In revisiting satisficing, we observe that the essence of satisficing is tradeoff. Unlike heuristics, which derive their justification from empirical phenomena, and unlike optimal solutions, which derive their justification by an evaluation of alternatives, satisficing decision-making derives its justification by an evaluation of consequences. We formulate and present a satisficing decision paradigm that has its motivation in Herbert Simon''s work on bounded rationality. We characterize satisficing using a cost–benefit tradeoff, and generate a decision rule applicable to both designing intelligent machines as well as describing human behavior. (shrink)
This paper articulates a formal theory of belief incorporating three key theses: (1) belief is a dyadic relation between an agent and a property; (2) this property is not the belief's truth condition (i.e., the intuitively self-ascribed property which the agent must exemplify for the belief to be true) but is instead a certain abstract property (a thought-content) which contains a way of thinking of that truth condition; (3) for an agent a to have a belief about such-and-such items it (...) is necessary that a possesses a language of thought, M a , and that a (is disposed as one who) inwardly affirms a sentence of M a in which there are terms that denote those objects.Employing an extended version of E. Zalta's system ILAO, the proffered theory locates thought-contents within a typed hierarchy of senses and their modes of presentation, the provisional definitions of which (suppressing complications added later to accommodate the contents of beliefs about beliefs) are as follows. A mode of presentation of e is a ternary relation of the sort [xyz z is a name in M y that denotes x, and D e yz] in which D e is an e-determiner – a relation between agents and their mental expressions imposing a syntactico-semantic condition sufficient for such an expression to denote e therein. A sense of an entity e is an abstract property that contains a mode of presentation R e of e by dint of encoding its property-reduct [x(y)(z)R e xyz]. In particular, a thought-content is a sense T of an ordinary first-order property P containing a mode of presentation whose P-determiner D P is such that, for any y and z, D P yz entails that z is a -abstract [ v S] of M y in which S is a sentence whose non-logical parts stand in appropriate semantic relations to the constituents of T's (some of which may themselves be senses).

In this paper I explain what is the difference between a book and a document according to Levinas. T hen I explain why, although he was very reluctant to read "cabalistic documents" he was interested by R. Haïm of Volozin's book, Nefesh HaHaïm, and even praised the French translation of the book as an event worth the attention of Jews, Christians and Muslims. T he main point is concerns his understanding of God "from our view point".
