Isaac Newton's Scientific Method examines Newton's argument for universal gravity and his application of it to resolve the problem of deciding between geocentric and heliocentric world systems by measuring masses of the sun and planets. William L. Harper suggests that Newton's inferences from phenomena realize an ideal of empirical success that is richer than prediction. Any theory that can achieve this rich sort of empirical success must not only be able to predict the phenomena it purports to explain, (...) but also have those phenomena accurately measure the parameters which explain them. Harper explores the ways in which Newton's method aims to turn theoretical questions into ones which can be answered empirically by measurement from phenomena, and to establish that propositions inferred from phenomena are provisionally accepted as guides to further research. This methodology, guided by its rich ideal of empirical success, supports a conception of scientific progress that does not require construing it as progress toward Laplace's ideal limit of a final theory of everything, and is not threatened by the classic argument against convergent realism. Newton's method endorses the radical theoretical transformation from his theory to Einstein's. Harper argues that it is strikingly realized in the development and application of testing frameworks for relativistic theories of gravity, and very much at work in cosmology today. (shrink)

Newton's methodology is significantly richer than the hypothetico-deductive model. It is informed by a richer ideal of empirical success that requires not just accurate prediction but also accurate measurement of parameters by the predicted phenomena. It accepts theory-mediated measurements and theoretical propositions as guides to research. All of these enrichments are exemplified in the classical response to Mercury's perihelion problem. Contrary to Kuhn, Newton's method endorses the radical transition from his theory to Einstein's. The richer themes of Newton's method are (...) strikingly realized in a challenge to general relativity from a new problem posed by Mercury's perihelion. †To contact the author, please write to: Talbot College, University of Western Ontario, London, Ontario, Canada N6A 3K7; e-mail: [email protected].

I take Newton's arguments to inverse square centripetal forces from Kepler's harmonic and areal laws to be classic deductions from phenomena. I argue that the theorems backing up these inferences establish systematic dependencies that make the phenomena carry the objective information that the propositions inferred from them hold. A review of the data supporting Kepler's laws indicates that these phenomena are Whewellian colligations-generalizations corresponding to the selection of a best fitting curve for an open-ended body of data. I argue that (...) the information theoretic features of Newton's corrections of the Keplerian phenomena to account for perturbations introduced by universal gravitation show that these corrections do not undercut the inferences from the Keplerian phenomena. Finally, I suggest that all of Newton's impressive applications of Universal gravitation to account for motion phenomena show an attempt to deliver explanations that share these salient features of his classic deductions from phenomena.

This is a very important book. It has already become required reading for researchers on the relation between the exact sciences and Kant’s philosophy. The main theme is that Kant’s continuing program to find a metaphysics that could provide a foundation for the science of his day is of crucial importance to understanding the development of his philosophical thought from its earliest precritical beginnings in the thesis of 1747, right through the highwater years of the critical philosophy, to his last (...) unpublished writings in the Opus postumum. In the course of articulating this theme, Friedman has made extensive use of detailed historical information about their scientific and mathematical background to illuminate Kant’s texts. Over and over again, such information is used to suggest interesting and quite subtle interpretations for texts that may have seemed puzzling or just wrong-headed. (shrink)

In this paper, I consider the thesis advanced by Lawrence J. Schneiderman and Nancy S. Jecker that physicians should be forbidden from offering futile treatments to patients. I distinguish between a version of this thesis that is trivially true and Schneiderman and Jecker's more substantive version of the thesis. I find that their positive arguments for their thesis are unsuccessful, and sometimes quite misleading. I advance an argument against their thesis, and find that, on balance, their thesis should be rejected. (...) I briefly argue that a resolution of the debate about medical futility will require addressing deeper issues about value. (shrink)

This article by Curtis Wilson is an account of the origin of Hansen’s powerful systematic method for finding contributions of higher order perturbations in celestial mechanics. Hansen’s method was developed in the course of improving on Laplace’s treatment of the mutual perturbations of Jupiter and Saturn. This method, an entirely new way of doing celestial mechanics when it first appeared, later made possible the successful treatment of the complicated motions of our moon (see Wilson 2010). In this paper Wilson gives (...) a brief historical introduction followed by an account of relevant technical details of the Laplacian background, an account illustrating technical details in Hansen’s initial development in his Disquisitions of 1829, and a treatment illustrating details contributing to the achievement of Hansen’s more refined development in his Untersuchung of 1831. These details include conditional equations Hansen provides for checking the accuracy of calculations. Wilson also includes a detailed assessment showing the extraordinary improvement in empirical accuracy of Hansen’s treatment over the best earlier treatment of the Jupiter-Saturn interactions.

Recent advances in philosophy, artificial intelligence, mathematical psychology, and the decision sciences have brought a renewed focus to the role and interpretation of probability in theories of uncertain reasoning. Henry E. Kyburg, Jr. has long resisted the now dominate Bayesian approach to the role of probability in scientific inference and practical decision. The sharp contrasts between the Bayesian approach and Kyburg's program offer a uniquely powerful framework within which to study several issues at the heart of scientific inference, decision, and (...) reasoning under uncertainty. The commissioned essays for this volume take measure of the scope and impact of Kyburg's views on probability and scientific inference, and include several new and important contributions to the field.

As van Fraassen pointed out in his opening remarks, Henry Kyburg's lottery paradox has long been known to raise difficulties in attempts to represent full belief as a probability greater than or equal to p, where p is some number less than 1. Recently, Patrick Maher has pointed out that to identify full belief with probability equal to 1 presents similar difficulties. In his paper, van Fraassen investigates ways of representing full belief by personal probability which avoid the difficulties raised (...) by Maher's measure-theoretic version of the lottery paradox. Van Fraassen's more subtle representation dissolves the simple identification of full belief with maximal personal probability. His investigation exploits the richer resources for representing opinion provided by taking conditional, rather than unconditional, personal probability as fundamental. It has interesting implications for equivalent alternative approaches based on non-Archimedean probability, as well as for equivalent approaches in which assumption contexts representing full belief relative to suppositions are taken as fundamental.

This paper uses Popper's treatment of probability and an epistemic constraint on probability assignments to conditionals to extend the Bayesian representation of rational belief so that revision of previously accepted evidence is allowed for. Results of this extension include an epistemic semantics for Lewis' theory of counterfactual conditionals and a representation for one kind of conceptual change.

I attempt to persuade the reader that externalism admits of no plausible interpretation. I argue that reliability is a concept with very different contours from epistemic justification, and that attempts to explicate justification in terms of reliability must fail. I address several other forms of externalism, and also mixed forms of justification. I then argue that externalist theories of justification cannot close the gap between mere true belief and knowledge. I suggest that a fourth condition on knowledge is required, regardless (...) of whether justification is internalist or externalist. I argue that with such a fourth condition a strong internalist theory of justification is adequate to the task that remains in making true belief knowledge. Additionally, strong internalism is more satisfying to our intuitions than externalism and mixed forms of justification. (shrink)

In “On Calling God ‘Mother’” (this journal), I argued that the practice of referring to God exclusively in male terms is morally acceptable. Isham claims that I have argued that “God should be referred to exclusively in male terms.” He claims that the Bible refers to God in female terms. He hints that I may have engaged in “gender devaluation.” He claims that there is a “need for a deity with which women can both relate and identify.” The first of (...) Isham’s claims is simply false. I address the remaining criticisms at greater length. (shrink)

This paper includes a survey of decision theories directed toward exploring the adequacy of alternative approaches for application to game theoretic reasoning, a review of the classic results of von Neumann and Morgenstern and Nash about equilibrium solutions, an account of a recent challenge to the idea that solutions should be equilibria, and, finally, an explicit reconstruction and defense (using the resources of causal decision theory) of the classic indirect argument for equilibrium solutions.

Consider your right hand and a mirror image duplicate of it. Kant calls such pairs incongruent counterparts. According to him they have the following puzzling features. The relation and situation of the parts of your hand with respect to one another are not sufficient to distinguish it from its mirror duplicate. Nevertheless, there is a spatial difference between the two. Turn and twist them how you will, you cannot make one of them occupy the exact boundaries now occupied by the (...) other. In his 1768 paper, ‘Concerning the Ultimate Foundations of the Differentiation of Regions in Space’, Kant uses these claims to argue against relational accounts of space and goes on to argue that the difference between incongruent counterparts depends on a relation to absolute space as a whole. In his 1770 Inaugural Dissertation he argued that this difference could not be captured by concepts alone but required appeal to intuition. In the Prolegomena (1783) and again in the Metaphysical Foundations of Natural Science (1786) Kant appealed to these puzzling features of incongruent counterparts to support his transcendental idealism about space.

This paper explores how the Bayesian program benefits from allowing for objective chance as well as subjective degree of belief. It applies David Lewis’s Principal Principle and David Christensen’s principle of informed preference to defend Howard Raiffa’s appeal to preferences between reference lotteries and scaling lotteries to represent degrees of belief. It goes on to outline the role of objective lotteries in an application of rationality axioms equivalent to the existence of a utility assignment to represent preferences in Savage’s famous (...) omelet example of a rational choice problem. An example motivating causal decision theory illustrates the need for representing subjunctive dependencies to do justice to intuitive examples where epistemic and causal independence come apart. We argue to extend Lewis’s account of chance as a guide to epistemic probability to include De Finetti’s convergence results. We explore Diachronic Dutch book arguments as illustrating commitments for treating transitions as learning experiences. Finally, we explore implications for Martingale convergence results for motivating commitment to objective chances. (shrink)

WILLIAM HARPER University of Western Ontario BRIAN SKYRMS University of California at Irvine VII INTRODUCTION TO CAUSATION, CHANCE, AND CREDENCE The search for causes is so central to science that it has sometimes been taken as the defining attribute of the scientific enterprise. Yet even after twenty-five centuries of philosophical analysis the meaning of "cause" is still a matter of controversy, among scientists as well as philosophers. Part of the problem is that the servicable concepts of causation built out of Necessity, Sufficiency, Locality, and Temporal Precedence were constructed for a deterministic world-view which has been obsolete since the advent of quantum theory. A physically credible theory of causation must be, at basis, statistical. And statistical analyses of caus­ ation may be of interest even when an underlying deterministic theory is assumed, as in classical statistical mechanics. (shrink)

We argue that causal decision theory is no worse off than evidential decision theory in handling entanglement, regardless of one’s preferred interpretation of quantum mechanics. In recent works, Ahmed and Ahmed and Caulton : 4315–4352, 2014) have claimed the opposite; we argue that they are mistaken. Bell-type experiments are not instances of Newcomb problems, so CDT and EDT do not diverge in their recommendations. We highlight the fact that a Causal Decision Theorist should take all lawlike correlations into account, including (...) potentially acausal entanglement correlations. This paper also provides a brief introduction to CDT with a motivating “small” Newcomb problem. The main point of our argument is that quantum theory does not provide grounds for favouring EDT over CDT. (shrink)

The Akaike Information Criterion can be a valuable tool of scientific inference. This statistic, or any other statistical method for that matter, cannot, however, be the whole of scientific methodology. In this paper some of the limitations of Akaikean statistical methods are discussed. It is argued that the full import of empirical evidence is realized only by adopting a richer ideal of empirical success than predictive accuracy, and that the ability of a theory to turn phenomena into accurate, agreeing measurements (...) of causally relevant parameters contributes to the evidential support of the theory. This is illustrated by Newton's argument from orbital phenomena to the inverse-square law of gravitation. (shrink)

Modernism is both a contested aesthetic category and a powerful political statement. Modernist music was condemned as degenerate by the Nazis and forcibly replaced by socialist realism under the Soviets. Sympathetic philosophers and critics have interpreted it as a vital intellectual defence against totalitarianism, yet some American critics consider it elitist, undemocratic, and even unnatural. Drawing extensively on the philosophy of Heidegger and Badiou, Quilting Points proposes a new dialectical theory of faithful, reactive, and obscure subjective responses to musical modernism, (...) which embraces all the music of Western modernity.

My dissertation examines the significance of value creation in the work of Friedrich Nietzsche. In working out Nietzsche’s view, my strategy is twofold. I begin by reconstructing Nietzsche’s metaethical commitments, offering an interpretation of Nietzsche’s conception of values that shows it to be consistent, and then I explore the nature and importance of value creation to Nietzsche’s project. I argue that value creation provides the core of Nietzsche’s response to his two most significant concerns: the failures of traditional morality and (...) the loss of meaning in the modern world. In Chapter 1 I examine the current literature concerning Nietzsche’s metaethics. Recently, scholars have engaged in debates over whether Nietzsche offers a version of moral realism or anti-realism. I argue that neither side of this debate adequately captures Nietzsche’s understanding of value. Moreover, by starting from these contemporary categories we cannot make sense of the importance Nietzsche places on value creation. In Chapter 2 I defend my account of Nietzsche’s conception of value by examining two features of his view: the nature of valuing and the connection between values and reasons. I argue that Nietzsche presents standards of value that are internal to the activity of valuing, and I explore the standards of health and honesty. Nietzsche’s strategy becomes clearer when we examine the connection he makes between values and tastes, and my view has the added interpretive benefit of revealing a motivation for Nietzsche’s untraditional philosophical methodology. In Chapters 3-4 I examine the processes and functions of value creation. I begin with the historical examples of value creation Nietzsche presents, and from these I elucidate the task of value creation. I argue that Nietzsche’s aim through value creation is the development of richer, shared sensibilities or forms of concern, which provide the foundation for a new approach to ethical reasoning and justification. Furthermore, value creation comprises Nietzsche’s principal strategy to avert nihilism. My development of value creation as both a new ethical ideal and a source of meaning results in a surprising conclusion about Nietzsche’s view of social relations. Many read Nietzsche as a radical individualist, believing his ideal of value creation must require solitude or the life of a hermit. Yet, value creation is best understood as a social activity. Despite Nietzsche’s reliance on the solitary individual, I suggest that Nietzsche’s commitments to value creation are best captured by a model of competitive collaboration, which he calls friendship. The contribution of my project extends beyond mere Nietzsche interpretation. In Chapter 5 I argue that Nietzsche offers compelling arguments that address contemporary ethical debates. I offer a Nietzschean critique of a recent call for value creation by J. David Velleman. I conclude by suggesting that Nietzsche offers an intriguing twist on Bernard Williams’ conception of ethical confidence; creating values creates the normative concepts that provide the basis for meaningful action.

Each of the five volumes in the Stone Art Theory Institutes series—and the seminars on which they are based—brings together a range of scholars who are not always directly familiar with one another’s work. The outcome of each of these convergences is an extensive and “unpredictable conversation” on knotty and provocative issues about art. This fourth volume in the series, _Beyond the Aesthetic and the Anti-Aesthetic_, focuses on questions revolving around the concepts of the aesthetic, the anti-aesthetic, and the political. (...) The book is about the fact that now, almost thirty years after Hal Foster defined the anti-aesthetic, there is still no viable alternative to the dichotomy between aesthetics and anti- or non-aesthetic art. The impasse is made more difficult by the proliferation of identity politics, and it is made less negotiable by the hegemony of anti-aesthetics in academic discourse on art. The central question of this book is whether artists and academicians are free of this choice in practice, in pedagogy, and in theory. The contributors are Stéphanie Benzaquen, J. M. Bern­stein, Karen Busk-Jepsen, Luis Camnitzer, Diarmuid Costello, Joana Cunha Leal, Angela Dimitrakaki, Alexander Dumbadze, T.

With the rejection of group selectionist derivations of ecological phenomena so incisively given by George Williams in 1966,43 Nicholson's long-ignored messages met with acceptance. Species benefit became, explicitly, incidental. But the reorientation was not just about a point of ecological theory. It was more fundamentally about theoretical style, the element shared by Wynne-Edwards' work and the newer, evolutionary ecology. That current approach is well expressed in an already classic paper by the British plant ecologist John Harper: Ultimately all the (...) discoveries of descriptive, production or population ecology must find their meaning in evolutionary phenomena... Evolutionary thinking concentrates attention on the behaviour of the individual and his descendants. If nothing in biology has meaning except in the light of evolution and if evolution is about individuals and their descendants — i.e. fitness — we should not expect to reach any depth of understanding from studies that are based at the level of the superindividual... What we see as the organised behaviour of systems is the result of the fate of individuals.44The emphasis in this passage is on style of thinking more than on study matter. What is so different from earlier ecologists is the rejection of the superorganism and its associated baggage of selfimposed constraints in an end-oriented process, such as balance of nature or species-level adaptation.The hallmark of post-1959 evolutionary ecology is the recognition, the making explicit of the question that the selective, genetical process of fitness (fates of genes) has to be separated from the observations of different levels of adaptiveness. An easy conflation of cause and result is no longer satisfying; now attempts to disentangle the complex strands tying population phenomena to the different levels of selection are providing the excitement of a new research program. In this program evolutionary theory is used to define the appropriate questions, as exemplified by the organization of the textbook Evolutionary Ecology.45 Our discussion of the invention of a new approach, with a characteristic style and set of interests, must also be about how the practitioners of ecology have perceived themselves. The early attempts of Poulton and Nicholson were not taken up by the vigorously growing science of ecology, which developed first - and intentionally — along a narrower, hierarchically restrained set of questions about population. The depth of Poulton's and Nicholson's submergence is indicated by the fact that even Wynne-Edwards did not argue in the manner of one rescuing a minor tradition. Rather, he thought he had a new approach, that of placing evolution in the foundations of ecology. Although this approach was not exactly original, we should be cautious in grouping all evolutionary concerns within ecology in one intellectual tradition. The particular style of selectionist deduction invigorated by Wynne-Edwards was successful only in the volatile situation of a rapidly growing discipline, full of self-critical examination and new rigor. Whereas in 1930 evolutionary concerns did not provide that rigor, by 1960 they could - and did. (shrink)

William Faulkner (1897-1962), one of the United States’ most renowned authors, was born on Sept. 25, 1897, in New Albany, Mississippi. He initially focused on poetry, culminating in his first publication: The Marble Faun (1924). Subsequently, he transitioned to prose, producing novels such as The Sound and the Fury (1929), As I lay Dying (1930), Light in August (1932) and Absalom, Absalom! (1936), which are considered his most significant works. Like most of his oeuvre, these novels are set in (...) a fictional Southern region that Faulkner termed ‘Yoknapatawpha county.’ Nearly all works set in this fictional county are characterized by themes of race, incest, the American Civil War, and the decline of the antebellum South. Faulkner frequently employs diverse perspectives and techniques that directly represent the consciousness of his characters. Recognition for his literary achievements came relatively late in his career. The primary catalyst for this recognition was the Nobel Prize for Literature awarded to him in 1949, when he had arguably passed the zenith of his writing career. Faulkner’s extensive oeuvre, which spans from 1924 to 1962, also encompasses lesser-known works, such as Sanctuary (1931) and Intruder in the Dust (1948). In addition to novels, Faulkner authored numerous short stories that are considered among the finest in American literature. These include the story translated here, “Barn Burningr” originally published in 1939, in the June issue of Harper’s magazine. Faulkner died July 6 in Byhalia, Mississippi, of a heart attack. -/- In Dutch: William Faulkner (1897-1962) …, een van de beroemdste schrijvers uit de Verenigde Staten, werd geboren op 25 september 1897 in New Albany, Mississippi. Hij begon aanvankelijk met het schrijven van poëzie, wat resulteerde in zijn eerste publicatie: The Marble Faun (1924). Kort daarna liet hij poëzie voor wat het was en stortte hij zich op het proza. Dit leidde tot romans als The Sound and the Fury (1929), As I lay Dying (1930), Light in August (1932) en Absalom, Absalom! (1936) die als zijn belangrijkste werken worden beschouwd. Net als het merendeel van zijn oeuvre spelen deze romans zich af in een fictioneel Zuiden dat door Faulkner ‘Yoknapatawpha county’ genoemd werd. Vrijwel alle werken die zich in deze fictieve streek afspelen, worden gekenmerkt door thema’s als ras, incest, de Amerikaanse burgeroorlog en de teloorgang van het oude Zuiden. Faulkner maakt vaak gebruik van verschillende perspectieven en technieken die direct het bewustzijn van zijn personages representeren. Pas relatief laat in zijn carrière kreeg hij erkenning voor zijn literaire verdiensten. De belangrijkste stimulans hiervoor was de Nobelprijs voor de literatuur die hem werd toegekend in 1949, toen hij als schrijver eigenlijk al over zijn toppunt heen was. Faulkners omvangrijke oeuvre, dat ontstond in de periode van 1924 tot 1962, omvat ook minder bekende werken, zoals Sanctuary (1931) en Intruder in the Dust (1948). Naast romans schreef Faulkner echter ook nog een groot aantal korte verhalen die tot de absolute top van het Amerikaanse verhaal gerekend worden. Daartoe behoort ook het hier vertaalde verhaal ‘In vlammen op’ (‘Barn Burning’), dat oorspronkelijk werd gepubliceerd in 1939, in het juninummer van het tijdschrift Harper’s. Faulkner stierf op 6 juli in Byhalia, Mississippi, aan een hartaanval. -/- . (shrink)

Not a full treatment of Newton’s scientific method, this book discusses his optical research only in passing (342–43). Its subtitle better indicates its scope: it focuses narrowly on the argument for universal gravitation in Book III of the Principia.

Newton claims his method is to “deduce” propositions “from phenomena.” On Harper’s interpretation Newton’s phenomena are patterns of data, which are used to measure “parameters” (...) by which the theory explains them. An example is Kepler’s Area Rule. Its fit to the data confirms the hypothesis that the force maintaining a body in orbit is directed toward the .. (shrink)

Did the September 11, 2001 terrorist attacks on the U.S. cause the values of teenagers in the U.S. to change? Did their previously important self-esteem and self-actualization values become less important and their survival and safety values become more important? Changes in the values of teenagers are important for practitioners, managers, marketers, and researchers to understand because high school students are our current and future employees, managers, and customers, and research has shown that values impact work and consumer-related attitudes and (...) behaviors. Further, studies that compared higher to lower performing for-profit and not-for-profit companies have found that higher performing organizations had strong values that permeated their organizations [Collins J.

The research results indicated that teenage survival, safety, and security values (a world at peace, freedom, national security, and salvation) increased in importance while their self-esteem and self-actualization values (a sense of accomplishment, inner harmony, pleasure, self-respect, and wisdom) decreased in importance, mirroring the changes for adults.

Essay review of William L. Harper, Isaac Newton’s scientific method. Turning data into evidence about gravity & cosmology. Oxford University Press, 2011; Steffen Ducheyne, The main business of natural philosophy. Isaac Newton’s natural-philosophical methodology. Springer, 2012. -/- The years 2011-12 will be regarded as memorable ones for the “Newtonian industry” since they have witnessed the publication of two beautiful and long awaited books devoted to Newton’s method and philosophy. They deserve great attention and praise, and I warmly recommend (...) them to any reader interested in 17th and 18th century science and philosophy. The favorable conjunction of 2011-12 should not come as a surprise for those who have been following the recent trends in Newtonian scholarship. Indeed, after the great generation of H.W. Turnbull, A. Koyré, I.B. Cohen, D.T. Whiteside, B.J.T. Dobbs, A.R. Hall, Mary Boas Hall, and R.S. Westfall, Isaac Newton has continued to be the object of intense historical research. In the 1990s, a new wave of historians of mathematics, who capitalized on the immense riches of Whiteside’s edition of the Mathematical Papers (1967–1981), produced a flood of essays devoted to rather technical aspects of Newton’s oeuvre. An incomplete list includes Michel Blay, Dana Densmore, Herman Erlichson, Bruce Brackenridge, François De Gandt, Bruce Pourciau, and Michael Nauenberg. Now the pendulum seems to be swinging towards philosophy, rather than mathematics, as is immediately apparent from the titles of the two books under review. The focus of Harper and Ducheyne’s books is Newton as the originator of a new method—an alternative and more effective method than the hypothetico-deductive one. In what follows I will not have the space to delve into all the details of the books under review: such a task would require one to exceed even the generous word limit granted by Perspectives on Science. What I will try to do is to provide the reader with an account of the main theses defended in these books by framing them within the context of their respective interpretative traditions. (shrink)

In this international and interdisciplinary collection of critical essays, distinguished contributors examine a crucial premise of traditional readings of Plato's dialogues: that Plato's own doctrines and arguments can be read off the statements made in the dialogues by Socrates and other leading characters. The authors argue in general and with reference to specific dialogues, that no character should be taken to be Plato's mouthpiece. This is essential reading for students and scholars of Plato.

We present a theoretical view of the cellular foundations for network-level processes involved in producing our conscious experience. Inputs to apical synapses in layer 1 of a large subset of neocortical cells are summed at an integration zone near the top of their apical trunk. These inputs come from diverse sources and provide a context within which the transmission of information abstracted from sensory input to their basal and perisomatic synapses can be amplified when relevant. We argue that apical amplification (...) enables conscious perceptual experience and makes it more flexible, and thus more adaptive, by being sensitive to context. Apical amplification provides a possible mechanism for recurrent processing theory that avoids strong loops. It makes the broadcasting hypothesized by global neuronal workspace theories feasible while preserving the distinct contributions of the individual cells receiving the broadcast. It also provides mechanisms that contribute to the holistic aspects of integrated information theory. As apical amplification is highly dependent on cholinergic, aminergic, and other neuromodulators, it relates the specific contents of conscious experience to global mental states and to fluctuations in arousal when awake. We conclude that apical dendrites provide a cellular mechanism for the context-sensitive selective amplification that is a cardinal prerequisite of conscious perception. (shrink)

Microbial ecology is flourishing, and in the process, is making contributions to how the ecology and biology of large organisms is understood. Ongoing advances in sequencing technology and computational methods have enabled the collection and analysis of vast amounts of molecular data from diverse biological communities. While early studies focused on cataloguing microbial biodiversity in environments ranging from simple marine ecosystems to complex soil ecologies, more recent research is concerned with community functions and their dynamics over time. Models and concepts (...) from traditional ecology have been used to generate new insight into microbial communities, and novel system-level models developed to explain and predict microbial interactions. The process of moving from molecular inventories to functional understanding is complex and challenging, and never more so than when many thousands of dynamic interactions are the phenomena of interest. We outline the process of how epistemic transitions are made from producing catalogues of molecules to achieving functional and predictive insight, and show how those insights not only revolutionize what is known about biological systems but also about how to do biology itself. Examples will be drawn primarily from analyses of different human microbiota, which are the microbial consortia found in and on areas of the human body, and their associated microbiomes (the genes of those communities). Molecular knowledge of these microbiomes is transforming microbiological knowledge, as well as broader aspects of human biology, health and disease. (shrink)
