Deontic Logic goes back to Ernst Mally’s 1926 work, Grundgesetze des Sollens: Elemente der Logik des Willens [Mally. E.: 1926, Grundgesetze des Sollens: Elemente der Logik des Willens, Leuschner & Lubensky, Graz], where he presented axioms for the notion ‘p ought to be the case’. Some difficulties were found in Mally’s axioms, and the field has much developed. Logic of Knowledge goes back to Hintikka’s work Knowledge and Belief [Hintikka, J.: 1962, Knowledge and Belief: An Introduction to the Logic of (...) the Two Notions, Cornell University Press] in which he proposed formal logics of knowledge and belief. This field has also developed quite a great deal and is now the subject of the TARK conferences. However, there has been relatively little work combining the two notions of knowledge (belief) with the notion of obligation. (See, however, [Lomuscio, A. and Sergot, M.: 2003, Studia Logica 75 63–92; Moore, R. C.: 1990, In J. F. Allen, J. Hendler and A. Tate (eds.), Readings in Planning, Morgan Kaufmann Publishers, San Mateo, CA]) In this paper we point out that an agent’s obligations are often dependent on what the agent knows, and indeed one cannot reasonably be expected to respond to a problem if one is not aware of its existence. For instance, a doctor cannot be expected to treat a patient unless she is aware of the fact that he is sick, and this creates a secondary obligation on the patient or someone else to inform the doctor of his situation. In other words, many obligations are situation dependent, and only apply in the presence of the relevant information. Thus a case for combining Deontic Logic with the Logic of Knowledge is clear. We introduce the notion of knowledge based obligation and offer an S5, history based Kripke semantics to express this notion, as this semantics enables us to represent how information is transmitted among agents and how knowledge changes over time as a result of communications. We consider both the case of an absolute obligation (although dependent on information) as well as the (defeasible) notion of an obligation which may be over-ridden by more relevant information. For instance a physician who is about to inject a patient with drug d may find out that the patient is allergic to d and that she should use d′ instead. Dealing with the second kind of case requires a resort to non-monotonic reasoning and the notion of justified belief which is stronger than plain belief, but weaker than absolute knowledge in that it can be over-ridden. This notion of justified belief also creates a derived notion of default obligation where an agent has, as far as the agent knows, an obligation to do some action a. A dramatic application of this notion is our analysis of the Kitty Genovese case where, in 1964, a young woman was stabbed to death while 38 neighbours watched from their windows but did nothing. The reason was not indifference, but none of the neighbours had even a default obligation to act, even though, as a group, they did have an obligation to take some action to protect Kitty. (shrink)

Recent articles in Religious Studies have underscored the questions of whether Buddhism presents any empirical doctrines, and whether, if it does, such doctrines are false or vacuous. In what follows I want to sketch an interpretation of Buddhism according to which it does not offer doctrines which are empirically false, on the one hand, or trivially true on the other. In doing so I take my cue from an earlier, and by now classic, paper by H. H. Price. For the (...) exposition of Buddhism I take the Pali Nikāyas, the single most significant collection of texts in the Buddhist tradition. The particular doctrine which is the focus of discussion here is the kammavāda or ‘karma view’ of early Indian Buddhism, for it is the focus of much of the recent literature cited above and a doctrine which some have thought amenable to statement in empirical terms.

Geannoteerde briefwisseling van de twee geleerden over het vraagstuk van de evolutie.

The biological sciences study (bio)complex living systems. Research directed at the mechanistic explanation of the "live" state truly requires a pluralist research program, i.e. BioComplexity research. The program should apply multiple intra-level and inter-level theories and methodologies. We substantiate this thesis with analysis of BioComplexity: metabolic and modular control analysis of metabolic pathways, emergence of oscillations, and the analysis of the functioning of glycolysis.

Timothy Williamson, in various places, has put forward an argument that is supposed to show that denying bivalence is absurd. This paper is an examination of the logical force of this argument, which is found wanting.

1. The most important aspect of touch is its relation to time and space, a relation which is established by the movement of touching itself. Referring to the ideas of E. Straus, the distinction between touching and being touched is elaborated in light of experiments done by us with animals. 2. Touching is: being in one's own limits and at the same time going beyond these limits, a situation in which the touched object is felt at the same time as (...) a "Gegenstand" and as "Mit-seiend." "Pour le tactile, c'est l'être à deux qui se place au premier rang" . The awareness of being by the sense of touch is particularly poignant in the case of touching oneself, which is an exceptional unity of the active and the passive state of mind. 3. The tactile recognition of form also presents a dialectic of activity and passivity, a dialectic which takes place in the form of a development which conquers time, and this after a scheme produced during the act of grasping itself. We refer to the studies of V. von Weizsäcker on the "Gestaltkreis." We must also remember the basic restlessness of the hand, which becomes lasting in the play of the hand with an object. 4. The hand can hold an object. In doing so a schematic tactile image is given, an image which functions as a hypothesis or as an organizing principle of the proleptic development of further tactile exploration. The phenomenological analysis of touch with the hand appears as a prefiguration of thought by synthetic judgments. Thus, it is true, as Herder remarked, and as Gold-stein and Merleau-Ponty confirmed, that perception by man and spiritual existence are identical. 5. Referring to the research of Révèsz and Palagyi, the real nature of the tactile world is anlyzed. Tactile exploration is done according to a real development, during which take place anticipatory and retrospective determinations which assure the continuity of the event and its meaning. Tactile perception permits description of the continuous unity of the discontinuous phases which we can state objectively "as if" expectation and memory, preliminary judgments and their checking, conceptual fixations and corrections had been put to work. 6. Important is the affective and emotional aspect of tactile impressions and their connection with inter-human relationships. 7. By touch, man establishes in a "feeling" way a personal relationship with the matter of things, which is hidden to the distance senses. This participation has a double aspect. It is like the birth of a "mood," of a "Befindlichkeit," but at the same time it is the active point of departure of a "feeling," of an "understanding," of an "inner grasp," of a being moved, of a being struck by the touched object which is then in our presence as a real "quale," as a material object, as a being in itself. We remember the proper nature of the caress, by which the "being together" of the caressed object complements that of the active caresser. The usual concepts by means of which, in practical and gnostic life, the most important tactile qualities are indicated intend to refer us to the characteristics of the things which take up space in the geometric world and in objectively measurable space, and on which is founded our natural orientation. We remember von Hornborstel's research on the intermodal characteristics of tactile impressions. These show us how a "knowledge" which accompanies perception can change an impression of feeling. The affective relationship, determined by a shaded "knowledge" and by a system of values, changes tangible reality, the substantiality of the body, of the "flesh." This affective change of matter, this "phenomenal transsubstantiation," easily becomes a reality in connection with objects of which we know that they belong or did belong to someone. The meaning which a thing has changes the matter of the object, an object which precisely by the touch is present "in the flesh." This is illustrated more precisely by the phenomena of fetishism, and by simple experiences of daily life. If we look for an anthropological point of view from which touch, of which the hand realizes the point of view will have to be attempted starting from the unimaginable certitude that the ontological unity of nature and spirit is in man the reality of a possible participation, a participation which, in our existence, is only indicated. The "restlessness" of the hand, never fulfilled and always searching, which we noted, is the human token of our concrete existence. Thus touch shows us what Valery remarked about the mind: "The mind is at the mercy of the body, as the blind are at the mercy of the seeing.". (shrink)

First published in 1818, The World as Will and Representation contains Schopenhauer's entire philosophy, ranging through epistemology, metaphysics, philosophy of mind and action, aesthetics and philosophy of art, to ethics, the meaning of life and the philosophy of religion, in an attempt to account for the world in all its significant aspects. It gives a unique and influential account of what is and is not of value in existence, the striving and pain of the human condition and the possibility of (...) deliverance from it. This new translation of the first volume of what later became a two-volume work reflects the eloquence and power of Schopenhauer's prose and renders philosophical terms accurately and consistently. It offers an introduction, glossary of names and bibliography, and succinct editorial notes, including notes on the revisions of the text which Schopenhauer made in 1844 and 1859. (shrink)

I argue that the concept of 'longitudinal form', which Poplawski and Gillett have introduced into ethical discussions about embryos and gametes, involves too many metaphysical subtleties to be a useful aid to making moral decisions. I conclude by suggesting a criterion for relevance in medical ethics.

Après avoir circonscript son sujet, l'auteur, en s'inspirant des travaux de Erwin Strauss, affronte les doctrines psychanalytiques concernant les états obsessionnelles. Il se livre en particulier à une critique du concept de libido orale et anale. Indépendemment des conceptions freudiennes il entreprend ensuite un examen de la relation entre liberté et obsession dans la réalisation de l'existence. Plus particulièrement il examine l'image de l'attirance de l'abîme comme obsession absolue. Et il s'efforce de délimiter ensuite les limites de la liberté par (...) rapport à la disposition à l'obsession vécue. L'étude se concentre ensuite sur le sujet de l'obsession et de la quasi-obsession dans la vie normale. A ce propos il examine successivement les expériences obsessionnelles qui peuvent être vécues d'une manière plus ou moins quotidienne et qui sont les suivantes : Représentations et pensées obsédantes en état d'insomnie ; l'étrangeté vécue comme obsédente ; l'état de trouble caractéristique à la situation du seuil comme obsession vécue ; 'je dois faire ce que je ne veux pas faire' ; à propos de certains gestes superstitieux comme manifestation d'une angoisse passagère ; 'quelque chose m'agace' ; 'ce que j'ai fait me tourmente'.

Context: Doctors have been known to treat or give consultation to patients informally, with none of the usual record keeping or follow up. They may wish to know whether this practice is ethical.Objective: To determine whether this practice meets criteria of medical ethics.Design: Informal medicine is analysed according to standard ethical principles: autonomy, beneficence and non-maleficence, distributive and procedural justice, and caring.Setting: Hospital, medical school, and other settings where patients may turn to physicians for informal help.Conclusion: No generalisation can be (...) made to the effect that informal medicine is or is not ethical. Each request for informal consultation must be considered on its own merits.Guidelines: Informal medicine may be ethical if no payment is involved, and when the patient is fully aware of the benefits and risks of a lack of record keeping. When an informal consultation does not entail any danger to the patient or others, the physician may agree to the request. If, however, any danger to the patient or others is foreseen, then the physician must insist on professional autonomy, and consider refusing the request and persuading the patient to accept formal consultation. If a reportable infectious disease, or other serious danger to the community, is involved, the physician should refuse informal consultation or treatment, or at least make a proper report even if the consultation was informal. If agreeing to the request will result in an unfair drain on the physician’s time or energy, he or she should refuse politely. (shrink)
