Many objects in the world have functions. Typewriters are for typing. Can-openers are for opening cans. Lawnmowers are for cutting grass. That is what these things are for. Every day around the world people attribute functions to objects. Some of the objects with functions are organs or parts of living organisms. Hearts are for pumping blood. Eyes are for seeing. Countless works in biology explain the “Form, Function, and Evolution of... ” everything from bee dances to elephant tusks to pandas’ (...) ‘thumbs’. Many scientific explanations, in areas as diverse as psychology, sociology, economics, medical research, and neuroscience, rest on appeals to the function and/or malfunction of things or systems. They talk of how humans and other organisms or their parts work, what their functions are, why they are present, and how different situations will affect them and how they will react. Philosophers, going back to Aristotle, used to make generous use of functions in describing objects, organisms, their interactions, and even as the basis of ethics and metaphysics. And yet, since the Enlightenment, talk of the function of natural objects, teleological function, began to be viewed with suspicion, as the mechanical model of the world replaced the old Aristotelian model. From a religious standpoint, it used to be easy to see how objects in the natural world could have natural functions, for God was said to instill functions by design throughout Creation. But philosophers became increasingly reluctant to invoke God to solve every difficult philosophical problem, and became unwilling to indulge in such religious explanations of teleology. (shrink)

Recent experiments have shown that people iconically modulate their prosody corresponding with the meaning of their utterance. This article reports findings from a story reading task that expands the investigation of iconic prosody to abstract meanings in addition to concrete ones. Participants read stories that contrasted along concrete and abstract semantic dimensions of speed and size. Participants read fast stories at a faster rate than slow stories, and big stories with a lower pitch than small stories. The effect of speed (...) was distributed across the stories, including portions that were identical across stories, whereas the size effect was localized to size-related words. Overall, these findings enrich the documentation of iconicity in spoken language and bear on our understanding of the relationship between gesture and speech. (shrink)

The transformers that drive chatbots and other AI systems constitute large language models (LLMs). These are currently the focus of a lively discussion in both the scientific literature and the popular media. This discussion ranges from hyperbolic claims that attribute general intelligence and sentience to LLMs, to the skeptical view that these devices are no more than “stochastic parrots”. I present an overview of some of the weak arguments that have been presented against LLMs, and I consider several of the (...) more compelling criticisms of these devices. The former significantly underestimate the capacity of transformers to achieve subtle inductive inferences required for high levels of performance on complex, cognitively significant tasks. In some instances, these arguments misconstrue the nature of deep learning. The latter criticisms identify significant limitations in the way in which transformers learn and represent patterns in data. They also point out important differences between the procedures through which deep neural networks and humans acquire knowledge of natural language. It is necessary to look carefully at both sets of arguments in order to achieve a balanced assessment of the potential and the limitations of LLMs. (shrink)

Gesture-first theories of language origins often raise two unsubstantiated arguments against vocal origins. First, they argue that great ape vocal behavior is highly constrained, limited to a fixed, species-typical repertoire of reflexive calls. Second, they argue that vocalizations lack any significant potential to ground meaning through iconicity, or resemblance between form and meaning. This paper reviews the considerable evidence that debunks these two “myths”. Accumulating evidence shows that the great apes exercise voluntary control over their vocal behavior, including their breathing (...) apparatus, larynx, and supralaryngeal articulators. They are also able to learn new vocal behaviors, and even show some rudimentary ability for vocal imitation. In addition, an abundance of research demonstrates that the vocal modality affords rich potential for iconicity. People can understand iconicity in sound symbolism, and they can produce iconic vocalizations to communicate a diverse range of meanings. Thus, two of the primary arguments against vocal origins theories are not tenable. As an alternative, the paper concludes that the origins of language – going as far back as our last common ancestor with great apes – are rooted in iconicity in both gesture and vocalization.

Charles Darwin "had medicine in his blood" (Bynum 1983). His father and grandfather were physicians, and he himself studied medicine. Although Darwin left medical school after two years and did not become a physician, he retained a strong interest in medicine and regularly used examples drawn from human biology and medicine in his writings. Clearly, he believed that medicine fell within the purview of his theory of evolution, and he recognized the ways in which the study of evolution and of (...) medicine could be mutually enriching. In The Descent of Man (1871), Darwin argued that humans, like other species, have evolved from earlier, ancestral species. "Descent with modification," Darwin's term for evolution, accounts ..

Lachman, Grace and Gaylord have argued that for bioethics education for undergraduate nursing students, a preferred combination of instruction involves a clinically-based nurse with ethics training and a philosophically-based ethicist with clinical training. At the University of Pennsylvania School of Nursing, undergraduate nursing ethics instruction takes this form. The course director is a philosopher with extensive clinical experience in ethics. The course utilises four distinct forms of nursing clinical inputs to educate undergraduate nursing students using a unique combination of didactic (...) and experiential learning exercises to simulate real ethics cases. This paper describes how the course was developed and refined over the past several years and suggests several ideas for improvements in nursing ethics education at an undergraduate level. (shrink)

Was Maimonides a radical philosopher who subtly argued for a naturalist world and who saw the obligation to keep the Torah's commandments as a social and moral obligation - or was he a conservative Jewish believer who only tried to formulate philosophical arguments in favour of a revealed religion? This question has been central to the interpretation of Maimonides from the 12th century until modern times. In the four chapters of this book, Shalom Sadik argues for a radical philosophical (...) interpretation of Maimonides. (shrink)

In his speech against Meidias Demosthenes describes the arrogant and proud behaviour of his opponent in which Meidias persists in spite of the popular vote condemning him. Whenever there is voting, Demosthenes says, Meidias is put forward as a candidate; he is the proxenos of Plutarch, he knows everything, the city is too small for his aspirations. This illustration of the enormous popularity of an Athenian politician shows his predominant influence in the two spheres of domestic and foreign policy. The (...) main line of this foreign policy —the passage is obviously intended as an accusation—is expressed by the relationship of proxenia and xenia between Meidias and Plutarch, the leading politician of Eretria who, pro-Athenian at first, changed his attitude and almost brought disaster on the Athenian army intervening in Euboea.

But what are functions? Here, 15 leading scholars of philosophy of psychology and philosophy of biology present new essays on functions.

It is shown that the Born Rule probabilities, i.e. the squares of the moduli of the coefficients in a pure state superposition, refer to mutually exclusive events consequent on measurement. It is also shown that the eigenstates in a pure state superposition are not mutually exclusive events. If the Born Rule is to be retained as the fundamental interpretative postulate of quantum mechanics then it follows, firstly, that the probabilities necessarily refer not to the eigenstates but to the eigenvalues to (...) which the eigenstates belong and, secondly, that the eigenvalues are necessarily mutually exclusive events. This means that to ask why a measurement of an observable on a system in a pure state superposition of eigenstates yields a single state rather than all the states in the superposition is to ill-pose the quantum measurement problem. The events the Born Rule probabilities properly refer to are not states but values. And it also means that the correctly-posed measurement problem, why does a measurement of an observable in a pure state superposition of the eigenstates of the observable yield a single eigenvalue rather than all the eigenvalues implicit in the superposition, admits of the answer: the values, being mutually exclusive events, constitute a statistical mixture of values, and as such, a measurement will yield just one of them.

Morton Arnsdorf, the book review editor of Perspectives in Biology and Medicine, was tragically killed in an automobile accident on June 9, 2010. Mort grew up in Chicago, went to college at Harvard, and then to medical school at the Columbia University College of Physicians and Surgeons. In college, Mort majored in History of Science, and he retained strong interests in history throughout his medical career. Mort did a residency in medicine at the University of Chicago, went back to Columbia (...) for fellowship training, and then joined the faculty of the University of Chicago in 1973. During his tenure in Chicago, he became Professor of Medicine and served both as Chief of the Section of Cardiology and as .. (shrink)

Quantum mechanics is seen to be incomplete not because it cannot explain the correlations that characterize entanglement without invoking either non-locality or realism, both of which, despite special relativity or no-go theorems, are at least conceivable. Quantum mechanics is incomplete, in a perhaps broader than hidden variable sense, because it fails to address within its theoretical structure the question of how even a single particle, by being in a given quantum state, causes the frequency distribution of measurement values specified by (...) the state. This incompleteness of quantum mechanics as it is currently conceived is both fundamental and indefeasible. Failure to address the question of how the states of entangled particles are given effect to yield the correlations they specify is simply a particular albeit attention arresting instance of this incompleteness. But if that is so then quantum mechanics cannot be held to be inconsistent with locality. (shrink)

A number of unique problems plague human research protection efforts at United States State and Territorial Departments of Health. The first problem is related to the number of Institutional Review Boards operated by and Federalwide Assurances held by DOHs. The lack of these two essential regulatory human research protection program mechanisms points to a possible inadequacy of infrastructure at DOHs for protecting human subjects. The second and third problems are related to the use and interpretation of research protection laws and (...) regulations at DOHs. Parsing public health activities into research or practice can be vexing and likely produces variability in how individual DOHs make the determination between research and practice and the outcomes of such decisions for the same or similar projects. A related problem is that DOH or Institutional Review Board officials might misclassify public health practice activities as research, which can have costly, adverse consequences. (shrink)

Richard Landau, the longtime editor of Perspectives in Biology and Medicine, died on November 3, 2015. Richard grew up in St. Louis. Like many people of his generation, he was inspired to become a physician by Paul de Kruif ’s book Microbe Hunters. Richard went to college and medical school at Washington University in St. Louis and came to the University of Chicago in 1940 as a resident in medicine. Except for a two-year stint in the army during World War (...) II, he spent the rest of his career at the university, rising through the academic ranks to become Professor of Medicine in 1959. Richard held several important administrative positions at the university; he served as Chief of the Section of Endocrinology.. (shrink)
