Universal theories with model completions are characterized. A new omitting types theorem is proved. These two results are used to prove the existence of a universal ℵ 0 -categorical partial order with an interesting embedding property. Other aspects of these results also are considered.

According tothe rationality thesis, the possession of propositional attitudes is inextricably tied to rationality. How in this context should we conceive of rationality? In one sense, being rational is contrasted with being non-rational, as when human beings are described as rational animals. In another sense, being rational is contrasted with being irrational. I shall call rationality in this latter senseevaluative rationality. Whatever else it might involve, evaluative rationality surely has to do with satisfying requirements of rationality such as, presumably, the (...) following:(1) That one avoid inconsistency in beliefs.(2) That one not adopt new beliefs unless what one knows entails or is evidence for the truth of those beliefs.(3) That one not have φing as a goal yet do nothing necessary for one to φ.

ARISTOTLE often claims that words are "homonymous" or "multivocal". He claims this about some of the crucial words and concepts of his own philosophy—"cause," "being," "one," "good," "justice," "friendship." Often he claims it with a polemical aim; other philosophers have wrongly overlooked homonymy and supposed that the same word is always said in the same way. Plato made this mistake; his accounts of being, good, and friendship are rejected because they neglect homonymy and multivocity. In Aristotle’s view Plato shared the (...) Socratic assumption about words and definitions. Socrates thought that when he asked "What is F?" some single definition of F could always be found to match the name "F." Aristotle thinks the Socratic question is important, but argues that it must be controlled by awareness of homonymy and multivocity. (shrink)

The paper describes the approach by which ethics are integrated into the undergraduate curriculum at Northern Illinois University''s College of Business. Literature is reviewed to identify conceptual frameworks for, and issues associated with, the teaching of business ethics. From the review, a set of guidelines for teaching ethics is developed and proposed. The objectives and strategies implemented for teaching ethics is discussed. Foundation and follow-up coursework, measurement issues and ancillary programs are also discussed.

Large Language Models (LLMs) have been transformative. They are pre-trained foundational models that are self-supervised and can be adapted with fine tuning to a wide range of natural language tasks, each of which previously would have required a separate network model. This is one step closer to the extraordinary versatility of human language. GPT-3 and more recently LaMDA can carry on dialogs with humans on many topics after minimal priming with a few examples. However, there has been a wide range (...) of reactions and debate on whether these LLMs understand what they are saying or exhibit signs of intelligence. This high variance is exhibited in three interviews with LLMs reaching wildly different conclusions. A new possibility was uncovered that could explain this divergence. What appears to be intelligence in LLMs may in fact be a mirror that reflects the intelligence of the interviewer, a remarkable twist that could be considered a Reverse Turing Test. If so, then by studying interviews we may be learning more about the intelligence and beliefs of the interviewer than the intelligence of the LLMs. As LLMs become more capable they may transform the way we interact with machines and how they interact with each other. Increasingly, LLMs are being coupled with sensorimotor devices. LLMs can talk the talk, but can they walk the walk? A road map for achieving artificial general autonomy is outlined with seven major improvements inspired by brain systems. LLMs could be used to uncover new insights into brain function by downloading brain data during natural behaviors. (shrink)

By recourse to the fundamentals of preference orderings and their numerical representations through linear utility, we address certain questions raised in Nover and Hájek 2004, Hájek and Nover 2006, and Colyvan 2006. In brief, the Pasadena and Altadena games are well-defined and can be assigned any finite utility values while remaining consistent with preferences between those games having well-defined finite expected value. This is also true for the St Petersburg game. Furthermore, the dominance claimed for the Altadena game over the (...) Pasadena game, and that would have been claimed for the St Petersburg game over the Altadena, can be contradicted without fear of inconsistency with the axioms of utility theory. However, insistence upon dominance can be made to yield a contradiction of the Archimedean axiom of utility theory. CiteULike Connotea Del.icio.us What's this? (shrink)

Professional Ethics: A Trust-Based Approach explores the unique nature of professional duty and virtue in light of the trust that professionals must invite, develop, and honor from those they intend to serve.

To explore how molecules became signs I will ask: “What sort of process is necessary and sufficient to treat a molecule as a sign?” This requires focusing on the interpreting system and its interpretive competence. To avoid assuming any properties that need to be explained I develop what I consider to be a simplest possible molecular model system which only assumes known physics and chemistry but nevertheless exemplifies the interpretive properties of interest. Three progressively more complex variants of this model (...) of interpretive competence are developed that roughly parallel an icon-index-symbol hierarchic scaffolding logic. The implication of this analysis is a reversal of the current dogma of molecular and evolutionary biology which treats molecules like DNA and RNA as the original sources of biological information. Instead I argue that the structural characteristics of these molecules have provided semiotic affordances that the interpretive dynamics of viruses and cells have taken advantage of. These molecules are not the source of biological information but are instead semiotic artifacts onto which dynamical functional constraints have been progressively offloaded during the course of evolution.

Theses on the semiotic study of life as presented here provide a collectively formulated set of statements on what biology needs to be focused on in order to describe life as a process based on semiosis, or sign action. An aim of the biosemiotic approach is to explain how life evolves through all varieties of forms of communication and signification (including cellular adaptive behavior, animal communication, and human intellect) and to provide tools for grounding sign theories. We introduce the concept (...) of semiotic threshold zone and analyze the concepts of semiosis, function, umwelt, and the like as the basic concepts for theoretical biology. (shrink)

Should a brain-dead woman be artificially maintained for the sake of her fetus? Does a physician have the right to administer a life-saving transfusion despite the patient's religious beliefs? Can a family request a hysterectomy for their retarded daughter? Physicians are facing moral dilemmas with increasing frequency. But how should these delicate questions be resolved and by whom? A Casebook of Medical Ethics offers a real-life view of the central issue involved in clinical medical ethics. Since the analysis of cases (...) plays a critical role in this study, the authors have assembled a broad collection of histories encountered in their work as medical ethics educators and consultants. The cases are developed in substantial detail to reflect the rich medical and psychosocial complexity involved, and each is brought to a decision point at which a course of action must be chosen. Among the issues examined are conflicts between patients' wishes and respect for their well-being, tensions concerning duties to patients unable to care for themselves and obligations to family members, and clashes between patient care obligations and the interests of other persons, including physicians, third parties, and the general public. The book also includes commentaries that combine general discussion of ethical principles with specific analysis of the cases examined in the text, as well as various options for resolving conflicts. Readers are invited to assess the comparative merits and liabilities of these approaches. An ideal text for undergraduate and medical school courses, A Casebook of Medical Ethics brings readers to the forefront of medicine, where they share in the determination of crucial ethical decisions.

Christian hope of resurrection requires that the one raised be the same person who died. Philosophers and theologians alike seek to understand the coherence of bodily resurrection and what accounts for numerical identity between the earthly and risen person. I address this question from the perspective of disability. Is a person with a disability raised in the age to come with that disability? Many theologians argue that disability is essential to one's identity such that it could not be eliminated in (...) the resurrection. What anthropology undergirds these claims is not often explicated. I argue that Thomistic hylemorphic anthropology provides the best context to understand the human person such that disability is not essential to identity. In the resurrection, we shall become truly ourselves. The marks of disability may remain, but Thomistic anthropology expresses the coherence of bodily resurrection in which one may hope for healing which eliminates the disability but not numerical identity.

Shared views regarding the moral respect which is owed to children in family life are used as a guide in determining the moral permissibility of nontherapeutic clinical research procedures involving children. The comparison suggests that it is not appropriate to seek assent from the preadolescent child. The analogy with interventions used in family life is similarly employed to specify the permissible limit of risk to which children may be exposed in nontherapeutic research procedures. The analysis indicates that recent writers misconceive (...) how certain moral principles, such as respect for personal autonomy, require us to act toward children. The results are also used to assess proposed federal regulations on research with children. (shrink)

Charles Travis promotes a conception of knowledge on which knowledge is unmistakable. I raise some issues about what he means by this. Though sympathetic to his project, I give reasons for doubting that he has shown that all knowledge depends on having proof.
