Some people have supposed that utility is good in itself, non-in-strumentally good, as distinct from good because conducive to other good things. And in modern versions of this view, utility often means want-satisfaction, as distinct from pleasure or happiness. For your want that p to be satisfied, is it necessary that you know or believe that p, or sufficient merely that p is true? However that question is answered, there are problems with the view that want-satisfaction is a non-instrumental good. (...) What if you want something only because you have a false belief? What if the time at which you want that p is fifty or five hundred years before the time to which p itself refers? To meet these difficulties, qualifications have to be introduced, and much has been written about how exactly these qualifications are to be framed.1 There is however what may be a rather more serious objection to the view that want-satisfaction is a non-instrumental good, or rather to the combination of that view with the principle that it is sufficient for your want that p to be satisfied simply that p is true. The objection is that this combination forces you to give undue weight to the mere acquisition of desires when you come to make judgements about changes in the value of things. It forces you to say that for any true proposition p, which initially you do not want to be true, your mere acquisition of a desire that p will, other things being equal, make the world better. Non-instrumental value can be increased merely by multiplying desires, even though everything else remains the same. Surely, however, improving the world is not as easy as that. (shrink)

Donation after circulatory determination of death (DCDD) is an accepted practice in the United States, but heart procurement under these circumstances has been debated. Although the practice is experiencing a resurgence due to the recently completed trials using ex vivo perfusion systems, interest in thoracoabdominal normothermic regional perfusion (TA-NRP), wherein the organs are reanimated in situ prior to procurement, has raised many ethical questions. We outline practical, ethical, and equity considerations to ensure transplant programs make well-informed decisions about TA-NRP. We (...) present a multidisciplinary analysis of the relevant ethical issues arising from DCDD-NRP heart procurement, including application of the Dead Donor Rule and the Uniform Definition of Death Act, and provide recommendations to facilitate ethical analysis and input from all interested parties. We also recommend informed consent, as distinct from typical “authorization,” for cadaveric organ donation using TA-NRP. (shrink)

"The fixed person for fixed duties, who in older societies was such a godsend, in the future ill be a public danger." Twenty years ago, a single legal metaphor accurately captured the role that American society accorded to physicians. The physician was "c- tain of the ship." Physicians were in charge of the clinic, the Operating room, and the health care team, responsible - and held accountabl- for all that happened within the scope of their supervision. This grant of responsibility (...) carried with it a corresponding grant of authority; like the ship's captain, the physician was answerable to no one regarding the practice of his art. However compelling the metaphor, few would disagree that the mandate accorded to the medical profession by society is changing. As a result of pressures from a number of diverse directions - including technological advances, the development of new health professionals, changes in health care financing and delivery, the recent emphasis on consumer choice and patients' rights - what our society expects phy- cians to do and to be is different now. The purpose of this volume is to examine and evaluate the conceptual foundations and the moral imp- cations of that difference. Each of the twelve essays of this volume assesses the current and future validity of the "captain of the ship" metaphor from a different perspective. The essays are grouped into four sections. In Section I, Russell Maulitz explores the physician's role historically. (shrink)

The theory of mental models and its computer implementations have led to crucial experiments showing that no standard logic—the sentential calculus and all logics that include it—can underlie human reasoning. The theory replaces the logical concept of validity (the conclusion is true in all cases in which the premises are true) with necessity (conclusions describe no more than possibilities to which the premises refer). Many inferences are both necessary and valid. But experiments show that individuals make necessary inferences that are (...) invalid, e.g., Few people ate steak or sole; therefore, few people ate steak. Other crucial experiments show that individuals reject inferences that are not necessary but valid, e.g., He had the anesthetic or felt pain, but not both; therefore, he had the anesthetic or felt pain, or both. Nothing in logic can justify the rejection of a valid inference: a denial of its conclusion is inconsistent with its premises, and inconsistencies yield valid inferences of any conclusions whatsoever including the one denied. So inconsistencies are catastrophic in logic. In contrast, the model theory treats all inferences as defeasible (nonmonotonic), and inconsistencies have the null model, which yields only the null model in conjunction with any other premises. So inconsistences are local. Which allows truth values in natural languages to be much richer than those that occur in the semantics of standard logics; and individuals verify assertions on the basis of both facts and possibilities that did not occur.

When do two mental items belong to the same life? We could be content with the answer -just when they have certain volitional qualities in common. An affinity is noted between that theory and Berkeley's early doctrine of the self. Some rivals of the volitional theory invoke a spiritual or physical owner of mental items. They run a risk either of empty formality or of causal superstition. Other rivals postulate a non-transitive and symmetrical relation in the set of mental items. (...) They must allow in consequence either for joint ownership of one and the same mental item, or for incompatible simultaneous decisions by one and the same person, or for new forms of death. This makes them disquieting. Another rival invokes a transitive and symmetrical relation defined in terms of co-consciousness. Even that allows for incongruous simultaneities. The volitional theory is free from such disadvantages. (shrink)

The self is one of the perennial topics in philosophy, and also one of the most debated. Its existence has been both defended and contested in equal measure by philosophers including Descartes and Hume. A Map of Selves: Beyond Philosophy of Mind proposes an original and compelling defense of selfhood. N. M. L. Nathan argues that the self is an enduring substance with a unique quality not shared with any other substance. He criticizes the panpsychist theory that material objects are (...) composed of selves analogous to ours and argues for the existence of at least one transcendent self, whose activity explains both our own existence and the existence of the natural world. He concludes by considering how the world would be for us if such selves did not exist, and we were, as some philosophers think we are, not selves, but, e.g., brains or simply sequences of mental events. A radical and innovative philosophical theory of the self, A Map of Selves: Beyond Philosophy of Mind will be of interest to those working on the philosophy of self and personal identity, philosophy of mind and metaphysics.

The purpose of the study is to identify a common theoretical basis for the study of human life as capital and unconditional higher value. Theoretical basis is based on the value-laden and revised structural constructivism, provided by the French philosopher and sociologist Pierre Bourdieu, critical analysis of the concepts of capital as the embodiment of social expectations, the biological concept of the value of human life, as well as the concepts of its sanctity. Originality. It is proved that one should (...) not consider the value of human life as capital only but instead takes into account its different value interpretations, especially when forming the social identity of a person. Moreover, in each of the value systems, the value of human life can be recognized as unconditional, which does not prevent the coexistence of such different value interpretations within the framework of one social identity, which then inevitably becomes a multiple social identity. Conclusions. Human life cannot be considered as a result of integrating economic expectations into the concept of "advertising" capital: first, expectations may well be inadequate; second, expectations by themselves are not directly related to capital; third, expectations do not necessarily lead to development; fourth, one should clearly distinguish between the spontaneous "expectations" and the values that express people’s strong motivation as members of social communities. The multiplicity of possible cultural conditions that affirm the unconditional value of life indicates that this unconditionality is always relevant rather than absolute. The multiple social identities could be used to add value to the protection of human life, the affirmation of multiple social identities is a means of affirming the unconditional value of human life – it is unconditional in several alternative ways.

Some Christians combine a doctrine about Christ which implies that there is more than one divine self with the doctrine that God revealed to the Jews a monotheism according to which there is just one divine self. I suggest that it is less costly for such Christians to achieve consistency by abandoning the second of these doctrines than to achieve it by abandoning the first.

In "Warrant and Proper Function" Plantinga argues that atheistic Naturalism is self-defeating. What is the probability that our cognitive faculties are reliable, given this Naturalism and an evolutionary explanation of their origins? Plantinga argues that if the Naturalist is modest enough to believe that it is irrational to have any belief as to the value of this probability, then he is irrational even to believe his own Naturalism. I suggest that Plantinga's argument has a false premise, and that even if (...) his argument were sound there would be reasons for doubting whether the Naturalist should respond to it by abandoning his Naturalism.

After briefly vindicating casuistries which successively apply a number of different moral principles, I describe some of the principles of justice liable to figure in such casuistries, assess the relative popularity of these principles and show that some of the most popular cannot be consistently applied in all circumstances.

Summary Tycho Brahe's lunar theory, mostly the work of his assistant Christian Longomontanus, published in the Progymnasmata (1602), was the most advanced and accurate lunar theory yet developed. Its principal innovations are: the introduction of equant motion for the first inequality in order to separate the determination of direction and distance; a more accurate limit for the second inequality although requiring a more complex calculation; additional inequalities of the variation and, in place of the annual inequality in Tycho's earlier theory, (...) a reduction in the equation of time; in the latitude theory a variation of the inclination of the orbital plane and an inequality of the motion of the nodes; a reduction in the range of variation of distance, parallax, and apparent diameter. Some of these were already present in Tycho's earlier lunar theory (1599), but all were changed in notable ways. Twenty years later Longomontanus published a modified version of the lunar theory in Astronomia Danica (1622), for the purpose of facilitating the calculation through new correction tables, and also explained his reasons for parts of the theory in the Progymnasmata. This paper is a technical study of both lunar theories. (shrink)

The purpose of this essay is to show that there was one person, perhaps only one, who developed a rigorously scientific cosmology nearly two thousand years ago. Cosmology is the largest of all subjects, with a long history, and the cosmology considered here is the one that endured for the longest part, nearly three-quarters, of that history. By cosmology I mean a description of the universe as a whole and of the arrangement of its principal parts. But by scientific cosmology, (...) I mean something more. For a cosmology to be considered scientific, three criteria must be met: it must be quantitative, physical, and empirical. Quantitative means that it must assign some scale of distances and sizes to its parts. Physical means that it must rest upon some kind of physical or mechanical principles, causes, for the ordering and motion of its parts. Finally, empirical means that it must either be derived from observation or, if derived theoretically, as from physical or mechanical principles, it must be confirmed by observation. I set out these criteria, which may not be exclusive or exhaustive but are surely within reason, in order to define our subject and exclude mythological or theological cosmologies, which generally meet none of the criteria, and philosophical cosmologies, as those of Plato, Aristotle, and Descartes, which may meet one or two in some way, although not rigorously, but surely do not meet all three. I am not concerned with whether the cosmology or the criteria upon which it is based are correct. Compared to our present understanding, the scale may be off by orders of magnitude, the physics may be entirely mistaken, and the observations may be inaccurate. But if all three are present I would call the cosmology scientific, and if not I would not call the cosmology scientific. (shrink)

_The purpose _of this article is to find out whether philosophical and anthropological studies of human nature affect the legitimization of decisions about human life and death, using the example of a philosophical analysis of the problem of euthanasia. _Theoretical__ basis._ Philosophically and anthropologically based situational analysis in bioethics is chosen as the research methodology, which reveals the legitimation of euthanasia as a complex and highly responsible moral decision, which should be based on both the consideration of all the patient’s (...) special circumstances and the competent and adequate application of fundamental knowledge about the human being. _Originality._ From a philosophical point of view, it would be correct to legalize euthanasia, but under the condition of significantly limiting the cases of its application, clearly defining the conditions for its provision and strict control over its implementation. It is morally unacceptable to justify either murder or torture, so euthanasia appears as an attempt to avoid both at the same time. _Conclusions._ Specific solutions to practical problems often indicate the necessary direction for solving theoretical difficulties. Thus, making proper moral decisions about euthanasia requires reliance on fundamental knowledge about human beings, but at the same time it provides arguments "for" and "against" artificial termination of life. The basic principles of bioethics – autonomy, nonmaleficence, beneficence and respect for the dignity of human life – serve as criteria for making balanced ethical decisions both in theory and in practice. These principles should be complemented by a coherent ethical, legal and philosophical position on euthanasia, which is achieved through legitimation procedures. Decisive for making a decision on euthanasia should be the strong desire of the patient himself. (shrink)

Context: Immunity includes cognitive concepts: the organism is thought to specifically recognize foreign materials and develop a memory of these encounters. Vaccines are thought to work by enhancing this immunological memory. Lymphocytes are key cells and specific antibodies are key molecules in immune recognition. Antibodies are blood proteins called “immunoglobulins.” Spontaneously formed immunoglobulins are seen as “natural” antibodies to dietary components and commensal bacteria. Immune cognition is used simply as a didactic metaphor. Problem: Do the cognitive aspects of immunology stem (...) from the activities of cells and molecules, or are they ascribed by the immunologist operating as a human observer? (1) An immense variety of immunoglobulins may bind to the same antigen with different binding energies. It is the immunologist who arbitrates the boundary between those that are specific (and declared antibodies) and those that are not. Specific antibodies serve as functional labels pasted onto natural immunoglobulins, as if they were recognizing elements. Is this “arbitration” the true cognitive event ascribed to immunoglobulins and lymphocytes? (2) A major impasse exists between progress in experimental immunology and its translation into clinical results. A proper understanding of immunological activity demands a wider view of an organism’s biology and, also, of the interference of human observers in delineating experimental realities, such as the specificity of immune recognition. Maturana’s biology of cognition and language provides one such approach. Method: Use of Maturana’s biology of cognition and language concepts to describe immunological activity. Results: A whole new understanding of immunological activity is suggested. Implications: A major change in the way of seeing is proposed that may eventually help the translation of this knowledge into clinical results. Furthermore, the immune system may also become a proper model for cognitive analyses. (shrink)
