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)

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)

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)

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)

Robert Grosseteste was a prolific theological and scientific writer, a translator, bishop of Lincoln , and a candidate for sainthood. There have been several studies of his life and his works, the most recent being that of Richard Southern. Nevertheless, James McEvoy's comment in 1983 that “the course of Grosseteste's life up until 1225 is almost completely unknown” remains largely true. The problem is common in medieval history—there is a dearth of reliable sources for the subject's early life. I do (...) not intend to discuss here Grosseteste's youth, or even his life until 1198 . I will accept, with a few reservations, the model Southern presented for Grosseteste's life until 1198 — that Grosseteste came from an undistinguished family, acquired an education, and may have taught in local schools; after serving the bishop of Lincoln in a minor capacity, he managed to obtain an administrative position under Bishop de Vere in the diocese of Hereford. Unfortunately, Bishop de Vere died on Christmas Day 1198, and his household was disbanded. It is the period following 1198 until 1225 that needs scrutiny. The recent discovery of a reference to Robert Grosseteste in a thirteenth-century cartulary demands that we reconsider the way in which historians have structured Grosseteste's career, both because of what this manuscript records and because of the light it sheds upon the methodology that has underpinned Grosseteste scholarship.

Upshot: According to Biology of Cognition and Language (Maturana’s approach) the immune system is not a cognitive system and defining of a cognitive paradigm is not what we understand as a Maturanian approach to immunology. The true cognitive actions in immunology are performed by immunologists acting as observers, not by body organs or systems. Stimuli and responses are not adequate concepts in the description of systems. As a closed network of cellular/molecular interactions, the immune system yields patterns of activity as (...) is transparent in robust conserved profiles of reactivity of natural immunoglobulins, as investigated by Nóbrega et al. and Cohen et al., which offer the opportunity to unravel its natural, spontaneous activity. Dietary materials, products of the commensal microbiome are the most abundant and common elements continuously incorporated to the network activity and, thus, also represent an important avenue of investigation.

A systematic study of rational or justified belief, which throws fresh light on current debates about foundations and coherence theories of knowledge, the validation of induction and moral scepticism. Dr Nathan focuses attention on the largely unsatisfiable desires for active and self-conscious assurance of truth liable to be engendered by philosophical reflection about total belief-systems and the sources of knowledge. He extracts a kernel of truth from the doctrine that a regress of justification is both necessary and impossible, contrasts the (...) resultant scepticism with more familiar complaints about the inapplicability of supposedly essential cognitive concepts and explores the feasibility of non-Humean modes of consolation. This is an original and carefully constructed book, which will interest professional philosophers and advanced students of epistemology. (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 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.
