William Bateson (1861-1926) has long occupied a controversial role in the history of biology at the turn of the twentieth century. For the most part, Bateson has been situated as the British translator of Mendel or as the outspoken antagonist of W. F. R. Weldon and Karl Pearson's biometrics program. Less has been made of Bateson's transition from embryologist to advocate for discontinuous variation, and the precise role of British and American influences in that transition, in the years (...) leading up to the publication of his massive Materials for the Study of Variation (1894). In this paper, I first attempt to trace Bateson's development in his early career before turning to search for the development of the moniker "anti-Darwinist" that has been attached to Bateson in well-known histories of the neo-Darwinian Synthesis.

This paper elaborates on administrative sorting, a threat to internal validity that has been overlooked in the regression discontinuity (RD) literature. Variation in treatment assignment near the threshold may still not be as good as random even when individuals are unable to precisely manipulate the running variable. This can be the case when administrative procedures, beyond individuals’ control and knowledge, affect their position near the threshold non-randomly. If administrative sorting is not recognized it can be mistaken as manipulation, preventing (...) fixing the running variable and leading to discarding viable RD research designs. (shrink)

In the literature investigating the long history of appeals to ‘nature’, in its multiple meanings, for rules of conduct or justification of social order, little attention has been paid to a long-standing tradition in which medical and physiological arguments merged into moral and social ones. A host of medical authors, biologists, social writers and philosophers assumed that nature spoke its moral language not only in its general economy, but also within and through the body. This is why, for instance, many (...) critics of Malthus argued that physiological self-regulating mechanisms ensured a spontaneous adaptation of fertility to the circumstances. Beliefs in a beneficent economy of nature persisted when Providence was replaced by evolution. To some, they provided reasons for hope even when others worried about ‘unfit’ members of society increasing at a quicker rate than ‘fit’ ones. The nerves gradually replaced food and blood as moral mediators between society and the body. When faith in bio-social progress was shaken by degeneration theories, and fin de siècle anxiety concerned underpopulation rather than overpopulation, not an insignificant proportion of those who emphasised the bad effects of modern civilisation resorted to ideas and arguments based on a view of the body in which physiology and morality worked together. A common language and common assumptions linked the Kulturpessimisten to their optimistic eighteenth-century colleagues, in spite of their different forecasts. The present paper traces continuities and discontinuities in the operation of a persistent set of interrelated ideas and assumptions on the coalescence of the physiological and the moral across disciplines and contexts.

Comparing the phenomenology, neurochemical pathology, and psychopharmacology of hallucinations and dreaming is limited by the available data. Evidence to date reveals no simple correspondence between the two states. Differences in the phenomenology of visual hallucinations and the visual component of dreams may reflect variations in visual context acting on the same underlying mechanism – the minimal visual input during dreaming contrasts with the more substantial perceived context in hallucinations. Variations in cholinergic, dopaminergic and serotonergic neurotransmitter function during sleep and during (...) hallucinations in Lewy body dementias, together with relevant drug effects suggest that, on the whole, different, potentially opposite, changes characterise the two states. A similar analysis of other psychotic features in Lewy body dementia and other disorders suggests that, in contrast to hallucinations, there may be more convincing parallels between dreaming and delusional states.

Summary Long-standing claims have been made for nearly the entire twentieth century that the biometrician, Karl Pearson, and his colleague, W. F. R. Weldon, rejected Mendelism as a theory of inheritance. It is shown that at the end of the nineteenth century Pearson considered various theories of inheritance (including Francis Galton's law of ancestral heredity for characters underpinned by continuous variation), and by 1904 he ?accepted the fundamental idea of Mendel? as a theory of inheritance for discontinuous (...) class='Hi'>variation. Moreover, in 1909, he suggested a synthesis of biometry and Mendelism. Despite the many attempts made by a number of geneticists (including R. A. Fisher in 1936) to use Pearson's chi-square (X 2, P) goodness-of-fit test on Mendel's data, which produced results that were ?too good to be true?, Weldon reached the same conclusion in 1902, but his results were never acknowledged. The geneticist and arch-rival of the biometricians, Williams Bateson, was instead exceptionally critical of this work and interpreted this as Weldon's rejection of Mendelism. Whilst scholarship on Mendel, by historians of science in the last 18 years, has led to a balanced perspective of Mendel, it is suggested that a better balanced and more rounded view of the hereditarian-statistical work of Pearson, Weldon, and the biometricians is long overdue.

There have been various attempts to apply Darwinian evolutionary theory to an understanding of the human condition within psychology and the social sciences. This paper evaluates whether Darwinian Theory can explain human consciousness. Starting with a brief definition of phenomenal consciousness and the central features of evolutionary theory, the paper examines whether random variations in the genome that confer a selective, reproductive advantage can explain both the emergence of consciousness and its varied forms. To inform the discussion, the paper reviews (...) what is known about the conditions for consciousness within the human mind/brain, understood in both structural (neural) terms and functional terms (in terms of human information processing), and concludes that “random variations in the genome” provide no explanatory mechanism for why some neural activities (but not others) are accompanied by consciousness. The paper then evaluates the many functional advantages that have been proposed for various forms of phenomenal consciousness once they emerge, and concludes that, on close examination, phenomenal experiences themselves do not carry out the information processing functions attributed to them, which challenges the Darwinian requirement that they could only have persisted (once emergent) it they enhanced reproductive fitness. The paper turns finally to what can be said about wider distribution of consciousness in non-humans, contrasting discontinuity theories with continuity theories. Discontinuity theories argue for a critical functional transition that “switches on consciousness” while continuity theories argue for a gradual transition in consciousness from unrecognisable to recognisable. All theories accept that there is an intimate, natural relationship of conscious experiences with their associated material forms. Consequently, as the material forms evolve, their associated experiences co-evolve—suggesting an indirect mechanism by which the emergence of species-specific forms of consciousness can be influenced by Darwinian evolution. It also allows a non-reductive understanding of human consciousness within the social sciences. (shrink)

This paper reconsiders the challenge presented to scientific realism by the semantic incommensurability thesis. A twofold distinction is drawn between methodological and semantic incommensurability, and between semantic incommensurability due to variation of sense and due to discontinuity of reference. Only the latter presents a challenge to scientific realism. The realist may dispose of this challenge on the basis of a modified causal theory of reference, as argued in the author’s 1994 book, The incommensurability thesis. This referential response has been (...) the subject of a charge of meta-incommensurability by Hoyningen-Huene et al., who argue that the realist’s referential response begs the question against anti-realist advocates of incommensurability. In reply, it is noted that a tu quoque rejoinder is available to the realist. It is also argued that the dialectical situation favours the scientific realist, since the anti-realist defence of incommensurability depends on an incoherent distinction between phenomenal world and world-in-itself. In light of such incoherence, and a strong commonsense presumption in favour of realism, the referential response to semantic incommensurability may be justifiably based on realism. (shrink)

In her ground-breaking and highly influential book Transformative Experience, L.A. Paul makes two claims: (1) one cannot evaluate and compare certain experiential outcomes (e.g. being a parent and being a non-parent) unless one can grasp what these outcomes are like; and (2) one can evaluate and compare certain intuitively horrible outcomes (e.g. being eaten alive by sharks) as bad and worse than certain other outcomes even if one cannot grasp what these intuitively horrible outcomes are like. We argue that the (...) conjunction of these two claims leads to an implausible discontinuity in the evaluability of outcomes. One implication of positing such a discontinuity is that evaluative comparisons of outcomes will not be proportionally sensitive to variation in the underlying features of these outcomes. This puts pressure on Paul to abandon either (1) or (2). But (1) is central to her view and (2) is very hard to deny. We call this the Shark Problem. (shrink)

It is often argued that the indispensability of continuum models comes from their empirical adequacy despite their decoupling from the microscopic details of the modelled physical system. There is thus a commonly held misconception that temperature varying across a region of space or time can always be accurately represented as a continuous function. We discuss three inter-related cases of temperature modelling — in phase transitions, thermal boundary resistance and slip flows — and show that the continuum view is fallacious on (...) the ground that the microscopic details of a physical system are not necessarily decoupled from continuum models. We show how temperature discontinuities are present in both data (experiments and simulations) and phenomena (theory and models) and how discontinuum models of temperature variation may have greater empirical adequacy and explanatory power. The conclusions of our paper are: a) continuum idealisations are not indispensable to modelling physical phenomena and both continuous and discontinuous representations of phenomena work depending on the context; b) temperature is not necessarily a continuously defined function in our best scientific representations of the world; and c) that its continuity, where applicable, is a contingent matter. We also raise a question as to whether discontinuous representations should be considered truly de-idealised descriptions of physical phenomena. (shrink)

Objectives: Treatment decisions in ethically complex situations are known to depend on a physician's personal characteristics and medical experience. We sought to study variability in decisions to withdraw or withhold specific life-supporting treatments in terminal care and to evaluate the association between decisions and such background factors.Design: Readiness to withdraw or withhold treatment options was studied using a terminal cancer patient scenario with alternatives. Physicians were asked about their attitudes, life values, experience, and training; sociodemographic data were also collected.Setting: Finnish (...) physicians, postal survey.Survey sample: Five hundred general practitioners, 300 surgeons, 300 internists, and 82 oncologists.Results: Treatments most often forgone were blood transfusion and thrombosis prophylaxis . Least willingly abandoned were intravenous hydration and supplementary oxygen . Female doctors were less likely to discontinue thrombosis prophylaxis and supplementary oxygen , but more readily x ray and laboratory examinations. Young doctors were more likely to continue antibiotics , thrombosis prophylaxis , supplementary oxygen and laboratory tests . Oncologists comprised the specialty most ready to forgo all studied treatments except antibiotics and blood transfusion. The family's wishes significantly increased treatment activity. Young and female practitioners and oncologists were most influenced by family appeal. Advance directives made decisions significantly more reserved and uniform. Different factors in the physician's background were found to predict decisions to withdraw antibiotics or IV hydration.Conclusion: The considerable variation observed in doctors' decisions to forgo specific life-sustaining treatments was seen to depend on their personal background factors. Experience, supervision, and postgraduate education seemed to be associated with more reserved treatment decisions. To increase the objectivity of end of life decisions, training, and research are of prime significance in this ethically complex area of medicine. (shrink)

The architects of the modern synthesis banned essentialism from evolutionary theory. This rejection of essentialism was motivated by Darwin’s theory of natural selection, and the continuity of evolutionary transformation. Contemporary evolutionary biology witnesses a renaissance of essentialism in three contexts: “origin essentialism” with respect to species and supraspecific taxa, the bar coding of species on the basis of discontinuities of DNA variation between populations, and the search for laws of evolutionary developmental biology. Such “new essentialism” in contemporary biology must (...) be of a new kind that accommodates relational (extrinsic) properties as historical essences and cluster concepts of natural kinds. (shrink)

The two essays in the volume follow a long tradition in critical discourse that turns to Art's domain as a source of inspiration, instruction, and as material for the construction of its concepts and the development of its problems. The case study of Suite Grunewald, 159+1 variations, by the artist Titus-Carmel, returns to a subject that has been eclipsed in past decades by the imperative to remember: namely, the creation of the new as an event, or rather, the event of (...) the new as creation. This is an especially vexatious problem following, on the one hand, the massive displacement of the subject as the author and creator of its works and, on the other, the introduction of the influential Deleuzian-Bergsonian notion of the new as immanent continuity rather than - as the commonsense notion would have it - a rupture, interruption, and discontinuity. The first essay develops this problematic by working alongside with Titus-Carmel variations / deconstruction of Grunewald's original painting of the "Crucifixion" as an exemplary site where the creation of the new - at once incalculable and necessary - finds a living and urgent expression. The second essay stages an encounter and sets free the resonances between the writing of Jean-Luc Nancy on and around the "body" and the cinema of Claire Denis as a cinema that mobilizes the force of bodies that it itself invents, and to which it gives a unique form of presence.

Deleuze reworks Marxist concepts in order to identify those that represent discontinuity and produce a theory of revolution. Marx is important because, along with Spinoza and Nietzsche, he is a part of a project to leave behind concepts such as transcendence and univocity which underlie the totalitarianism of traditional philosophy. Deleuze is looking for concepts that might form a different theory, within which the structures of production are not organised vertically by the domination of universal concepts, such as ‘being’ or (...) ‘essence’, but flow horizontally through a multiplicity of relations of conceptual singularity. The production of a different series of concepts is a strategic and tactical operation that, in confronting prior notions of transcendental philosophy, turns philosophy itself into a battlefield. Marx provides the general methodology for this tactical approach through two fundamental categories: production and conflict. Deleuze practises Marx's theoretical method and by using Marx's own central concepts challenges traditional Marxism, to arrive at a totally different and revolutionary philosophical structure based on concepts such as those of force, variation, difference, singularity, production and the war machine.

The last two centuries have been the centuries of the discovery of the cell evolution: in the XIX century of the germinal cells and in the XX century of two groups of somatic cells, namely those of the brain-mind and of the immune systems. Since most cells do not behave in this way, the evolutionary character of the brain-mind and of the immune systems renders human beings formed by two different groups of somatic cells, one with a deterministic and another (...) with an indeterministic (say Darwinian) behavior. An inherent consequence is that of the generation, during ontogenesis, of a dual biological identity. The concept of the dual biological identity may be used to explain the Kantian concept of the two metaphysical worlds, namely of the causal necessity and of the free will (Azzone, 2001). Two concepts, namely those of complex adaptive systems (CAS) and of emergence (Holland, 2002), are useful tools for understanding the mechanisms of adaptation and of evolution. The concept of complex adaptive systems indicates that living organisms contain series of stratified components, denoted as building blocks, forming stratified layers of increasing complexity. The concept of emergence implies the use of repeating patterns and of building blocks for the generation of structures of increasing levels of complexity, structures capable of exchanging communications both in the top-down and in the bottom-up direction. Against the concept of emergence it has been argued that nothing can produce something which is really new and endowed of causal efficacy. The defence of the concept of emergence is based on two arguments. The first is the interpretation of the variation-selection mechanism as a process of generation of information and of optimization of free energy dissipation in accord with the second principle of thermodynamics. The second is the objective evidence of the cosmological evolution from the Big Bang to the human mind and its products. Darwin has defended the concept of the continuity of evolution. However evolution should be considered as continuous when there is no increase of information and as discontinuous when there is generation of new information. Examples of such generation of information are the acquisition of the innate structures for language and the transition from absence to presence of morality. There are several discontinuity thresholds during both phylogenesis and ontogenesis. Morality is a relational property dependent on the interactions of human beings with the environment. Piaget and Kohlberg have shown that the generation of morality during childhood occurs through several stages and is accompanied by reorganization of the child mental organization. The children respect the conventions in the first stage and gradually generate their autonomous morality. The transition from absence to presence of morality, a major adaptive process, then, not only has occurred during phylogenesis but it occurs again in every human being during ontogenesis. The religious faith does not provide a logical justification of the moral rules (Ayala, 1987) but rather a psychological and anthropological justification of two fundamental needs of human beings: that of rendering Nature an understandable entity, and that of increasing the cooperation among members of the human societies. The positive effects of the altruistic genes in the animal societies are in accord with the positive effects of morality for the survival and development of the human societies. (shrink)

According to widespread opinion, the meaning of body part terms is determined by salient discontinuities in the visual image; such that hands, feet, arms, and legs, are natural parts. If so, one would expect these parts to have distinct names which correspond in meaning across languages. To test this proposal, we compared three unrelated languages—Dutch, Japanese, and Indonesian—and found both naming systems and boundaries of even basic body part terms display variation across languages. Bottom-up cues alone cannot explain natural (...) language semantic systems; there simply is not a one-to-one mapping of the body semantic system to the body structural description. Although body parts are flexibly construed across languages, body parts semantics are, nevertheless, constrained by non-linguistic representations in the body structural description, suggesting these are necessary, although not sufficient, in accounting for aspects of the body lexicon.

Kammerer and Frankish (this issue) suggest we evaluate introspection of mental states to examine consciousness, but in cephalopods we can only judge internal actions by behaviour output. We can look for mental states — perceptions, beliefs, and intentions — where the tight input–action linkage that is true for reflexes, instincts, and well-learned actions is discontinuous. Here the animal is internally evaluating the sensory input from previous information and making a decision before acting. Perceptions: the octopus motion parallax head bob (...) and wound tending. Beliefs: the cuttlefish delay of gratification. Intentions: use of previous information for future strategies in octopus win-switch foraging and carrying a coconut for future shelter. Intentions are also used in skin displays, their widespread directional lateralization, the octopus 'passing cloud' to startle an immobile prey, the cuttlefish eyespot dot production to repel only visual predators, and the cuttlefish males' deceptive use of the female skin display. These examples allow us to assume in what situations introspection might be used but tell us little about the process of these actions. However, the quantitative variation, laterality, and combination of different displays suggest that cephalopod sexual skin displays are a special case of linkage of internal evaluation to external output that needs further behavioural and neurophysiological assessment.

By studying history, we understand that religion in different ages is influenced by the culture of people. This reality signals the probability of that religion is made by people and it is the product of man in history. This probability indeed ignores the divinity of religion and presents it only as a human product. But is there only one probability for human influence? We should survey the relation between the human and divine in religion to clarify this question. By surveying (...) this relation, we understand that there is a fundamental discontinuity between the divine and human realms. Different objects could cause this discontinuity, but the most fundamental object is the power that causes the excellence and mastery of divine and fundamental discontinuity. If the power only is regarded, the probability ofhumanity of religion increases. But other objects may be regarded. If wisdom has an important place in the discontinuity, there is a probability for the influence of the human. It is wise divine variation of religion that correlates the eternal variation of the human. (shrink)

Graphical displays of simple moving geometrical figures have been repeatedly used to study the attribution of animacy in human observers. Yet little is known about the relevant movement characteristics responsible for this experience. The present study introduces a novel parametric research paradigm, which allows for the experimental control of specific motion parameters and a predictable influence on the attribution of animacy. Two experiments were conducted using 3D computer animations of one or two objects systematically introducing variations in the following aspects (...) of motion: directionality, discontinuity and responsiveness. Both experiments further varied temporal kinematics. Results showed that animacy experience increased with the time a moving object paused in the vicinity of a second object and with increasing complexity of interaction between the objects . The experience of animacy could be successfully modulated in a parametric fashion by the systematic variation of comparably simple differential movement characteristics. (shrink)

Individuals often revise their beliefs when confronted with contradicting evidence. Belief revision in the spatial domain can be regarded as variation of initially constructed spatial mental models. Construction and revision usually follow distinct cognitive principles. The present study examines whether principles of revisions which follow constructions under high task demands differ from principles applied after less demanding constructions. We manipulated the task demands for model constructions by means of the continuity with which a spatial model was constructed. We administered (...) tasks with continuous, semi-continuous, and discontinuous conditions as between-subject factor (experiment 1) and as within-subject factor (experiment 2). Construction and revision followed distinct cognitive principles in the changeless conditions of experiment 1. With increased task demands due to switches between different continuity conditions (experiment 2), reasoners adapted the principles they used for model revisions to the principles which they had used during antecedent constructions.

How do people gather samples of evidence to learn about the world? Adults often prefer to sample evidence from diverse sources—for example, choosing to test a robin and a turkey to find out if something is true of birds in general. Children below age 9, however, often do not consider sample diversity, instead treating non‐diverse samples (e.g., two robins) and diverse samples as equivalently informative. The current study (N = 247) found that this discontinuity stems from developmental changes in standards (...) for evaluating evidence—younger children chose to learn from samples that best approximate idealized views of what category members are supposed to be like (e.g., the fastest cheetahs), with a gradual shift across age toward samples that cover more within‐category variation (e.g., cheetahs of varying speeds). These findings have implications for the relation between conceptual structure and inductive reasoning, and for the mechanisms underlying inductive reasoning more generally. (shrink)

This study tested the two main neurocognitive models of dreaming by using cognitive data elicited from REM sleep in normals and narcoleptics. The two models were the ''activation-only'' view which holds that, in the context of sleep, overall activation of the brain is sufficient for consciousness to proceed in the manner of dreaming (e.g., Antrobus, 1991; Foulkes, 1993; Vogel, 1978); and the Activation, Input source, Modulation (AIM model), which predicts that not only brain activation level but also neurochemical modulatory systems (...) exert widespread effects upon dreaming (Hobson & McCarley, 1977; Hobson, Pace-Schott, & Stickgold, 2000). Mental activity was studied in nocturnal REM in 15 narcoleptics and 9 normal healthy persons and in REM at the onset of daytime naps and nighttime sleep (SOREM) in narcoleptics. The study was performed in the subjects' homes, using instrumental awakenings and ambulatory polysomnographic techniques, and focused upon visual vividness, mentation report length, improbable and discontinuous bizarre features, and reflective consciousness. Within each subject group, most cognitive variables tended to fluctuate in line with expected variations in circadian activation level. When comparing the cognitive variables between the two groups, reflective consciousness was clearly highest in narcoleptics, whereas improbabilities and discontinuities were lower, with mentation report length and visual vividness differing less between the groups. These findings are consistent with the AIM model of sleep mentation, but not with the activation-only model. (shrink)

David Bloor’s thesis claiming that the construction of the progressive vision of mathematical history is something artificial, because it does not take into account the civilizing and social discontinuities and variations. The author shows that the opposite declaration is equally true. He namely claims that the history emphasizing only incommensurabilities, differences and variations is something artificial.

Our objective will be to argue in favor of the idea that in Nietzsche there is no genealogical method, stricto sensu, with universalist and systemic-substantivist epistemic claims (traditionally conceived by justificationist and foundationalist philosophies from Plato to Hegel). However, there is a characteristic genealogical program, which opposes the majority genealogies and philosophies insofar as a self-suppression of the method is imposed as the primary and heterodox register of its reflection. We start from the hypothesis that Nietzsche’s genealogy, understood programmatically, became (...) viable because it was markedly structured on the basis of three reflexive movements that free his genealogical thinking from an analytical-methodological conduct, like the canon, which are: (i) variation of style in his writing; (ii) critical historicism or radical and (iii) discontinuity of origin. However, it would be pointless to show how clearly the Nietzschean genealogical program was outlined if we couldn’t say where it came from, for whom and for what purpose, or even more so, what it is intended to denounce. Therefore, in our conclusion, we will show, with some reservation, how the Nietzschean genealogical program lends itself to evaluating the dimension of power. (shrink)

The aim of Reverse Mathematics (RM for short) is to find the minimal axioms needed to prove a given theorem of ordinary mathematics. These minimal axioms are almost always equivalent to the theorem, working over the base theory of RM, a weak system of computable mathematics. The Big Five phenomenon of RM is the observation that a large number of theorems from ordinary mathematics are either provable in the base theory or equivalent to one of only four systems; these five (...) systems together are called the ‘Big Five’. The aim of this paper is to greatly extend the Big Five phenomenon as follows: there are two supposedly fundamentally different approaches to RM where the main difference is whether the language is restricted to second-order objects or if one allows third-order objects. In this paper, we unite these two strands of RM by establishing numerous equivalences involving the second-order Big Five systems on one hand, and well-known third-order theorems from analysis about (possibly) discontinuous functions on the other hand. We both study relatively tame notions, like cadlag or Baire 1, and potentially wild ones, like quasi-continuity. We also show that slight generalizations and variations of the aforementioned third-order theorems fall far outside of the Big Five. (shrink)

The body is at the heart of critical and phenomenological concerns, yet it is the soul that is increasingly under pressure. As we are being stripped of our structures of commonality, we need a renewed concept of political spirituality. My aim is to enrich Simondon’s concept of spirituality as transindividuality through Souriau’s transmodal architectonics. My argument proceeds in two steps: (i) I emphasize the precarious and communal modality of «having a soul», defining it as a possession without ownership and demonstrating (...) its inseparability from the problems of intensive variation and discontinuity. (ii) I then argue that Souriau is inspired by Leibniz’s disjunction between the ontic soul and the relational body, which holds the key to an account of spiritual commitment that exceeds the union of corporeal and psychical existences insofar as it invents a new common use for them.

This paper examines how the 19th-century British naturalist Alfred Russel Wallace used biogeographical mapping practices to draw a boundary line between Malay and Papuan groups in the colonial East Indies in the 1850s. Instead of looking for a continuous gradient of variation between Malays and Papuans, Wallace chose to look for a sharp discontinuity between them. While Wallace's "human biogeography" paralleled his similar project to map plant and animal distributions in the same region, he invoked distinctive "mental and moral" (...) features as more decisive than physical ones. By following Wallace in the field, we can see his field mapping practices in action -- how he conquered the problem of local particularity in the case of human variation. His experiences on the periphery of expanding European empires, far from metropolitan centers, shaped Wallace's observations in the field. Taking his cues from colonial racial categories and his experiences collaborating with local people in the field, Wallace constructed the boundary line between the Malay and Papuan races during several years of work in the field criss-crossing the archipelago as a scientific collector. This effort to map a boundary line in the field was a bold example of using the practices of survey science to raise the status of field work by combining fact gathering with higher-level generalizing, although the response back in the metropole was less than enthusiastic. Upon his return to Britain in the 1860s, Wallace found that appreciation for observational facts he had gathered in the field was not accompanied by agreement with his theoretical interpretations and methods for doing human biogeography.

Cis and transgender. Performativity as bodily and social habit In this article, I argue that habit formation provides a good starting point to understand gender identity. Judith Butler’s concept of ‘performativity’ indicates that gender identity comes about through a process of social and linguistic repetition of normative representations of gender. The phenomenological notion of ‘habitual identity’ that Maren Wehrle (2021) suggests, complements this notion of performativity, but should be complemented with a psychic aspect to attain a completer notion of performativity. (...) Understanding performativity in terms of habit formation seemingly also has a downside: does it not lead to repetition of the same in an environment of predominantly cis and binary gender identities? What does this mean now that more and more people identify as trans or non-binary? I argue that performativity does not necessarily involve the reproduction of cis and binary gender identities, because it includes the possibility of variation from the norm. While cis implies that body, identity and social ascriptions coincide, in the case of trans there are discontinuities between these three. Rather than considering cis and trans as opposites, performativity means understanding both as variations, of which the discontinuities between body, self and social ascriptions are more difficult to live.

Although the mathematics of interest is very precise, the practice of charging computing and disclosing interest or cost of credit is full of variations and therefore often questionable on ethical grounds. The purpose of this paper is to examine some of the prevalent practices which are incorrect, illogical, unfair or deceptive. Both utilitarian and formalist schools of ethical theory would find these practices to be inappropriate. The paper will specifically look at unfair practices in the areas of estimation of intrayear (...) rates, use of 360 days in a year, the "rule of 78th", interest rate ('APR') advertising, and computation of unpaid balance by credit card issuers to figure interest costs.The current practices are not in the best interest of the average consumer. There is, therefore, an urgent need for new legislation, change in regulatory code and disclosure requirement for eliminating these unethical practices. The author recommends that the Truth in Lending Code of the Federal Reserve should require the disclosure of the effective APR if the periodic rate is determined by dividing the 'APR' by the number of payment period in a year; the use of 360 days in a year methods and the "Rule of 78ths" should be immediately discontinued; Deceptive advertising, which tend to understate the true cost of credit or hides hidden costs and fees should be outlawed; interest should be payable with the same frequency as the frequency of compounding and credit card holders should be provided with a comparative example of various methods of balance computation.

The debate concerning the approach of the early Christians to the military can be advanced by paying attention to a genre of literature that scholars have largely ignored: the church orders. These documents-the "Apostolic Tradition, Canons of Hippolytus, Testament of Our Lord", and "Apostolic Constitutions" - are illuminating in that they deal with ethics within com- prehensive treatments of worship, catechesis and pastoral life. They also are useful in that they, as variations upon a common original, are means of monitoring (...) change across the third and fourth centuries. This article uses the church orders to assess four elements of a "new consensus" (David Hunter) on Christians in the military. By and large it confirms these, but at times it alters emphases and adds nuances. It argues that: (1) the church orders viewed killing as the big problem for Christians in the legions, not idolatry; (2) the church orders confirm that the pre-Christendom church was divided on Christian participation in the legions; (3) the church or- ders provide evidence for both discontinuity and continuity on the issue across the centuries, although the deepest continuity, based on John the Baptist's "rule" of Luke 3.14, is between the pre-Constantinian laity and later theologians; (4) the church orders confirm a regional variation in attitude and practice. The church orders' authority in practice is never clear. (shrink)

Hume's sections on the reason of animals are considered. He claims that animals show what we find extraordinary sagacity, in nest building and migration, as well as needing to learn many things from experience, just as we do. He issues a challenge to any rival account of our own powers to do as well or better than he does in accounting for the continuities, and discontinuities, between animal and human cognitive achievements. Yet when he looks at our ability to recognize (...) familiar lasting things, only in the Enquiry Concerning Human Understanding does he allow that animals do this just as we do. Does his Treatise account of what exactly we do, noting constancies and coherence in our impressions, so overlooking interruption and disguising variation, fail his own touchstone? (shrink)

This is one of the best and most complete treatments of Wittgenstein's philosophy written thus far in any language. The seven chapters of this substantial work mark the various stages of Wittgenstein's evolution giving appropriate attention to each of them. Gargani's analysis leaves unexamined few, if any, concrete issues where the ambiguity of Wittgenstein has provoked current discussion. Objects, properties, relations, complete definition and the determinateness of symbols, general propositions, language in the Tractatus, the object-designation scheme, imagination and thought, the (...) role of sense data, the concept of rule: these and other issues are all scrutinized in dialogue with the great wealth of existing opinion. But the author is never lost in questions of detail nor in polemical support of his interpretations as is so often the case with commentaries of this sort. Using Wittgenstein's methodological variations as a guiding thread, Gargani puts the above issues in perspective but, most importantly, he makes a thorough rational reconstruction, including continuities and discontinuities, of Wittgenstein's thought. One of the best features of this work is that it shows the intimate relations of Wittgenstein's work with Frege, Russell, Moore, Ramsey, Hertz, Schlick, Carnap, Neurath, and others.--A. M. (shrink)

In this chapter we will try to show how the introduction of Darwinian evolutionary theory transformed metaphysics, and in particular, the philosophical understanding of the temporality of being. In the interests of brevity, we will focus on two particularly significant aspects of the impact of Darwinism on Latin America. We will consider, first, how the new evolutionary thought transformed past notions of temporality. Second, we will discuss the ways in which the ideas of regression and extinction, viewed as essential components (...) of the evolutionary process, problematized the nature of progress and civilization. We trace these developments in the work of three central figures of Latin American thought: José Martí, José Rodó, and Euclides da Cunha. All three of these men were extraordinarily versatile thinkers, and each has been the subject of voluminous secondary literature. But the first two, unlike some other influential figures—such as, famously, Domingo Sarmiento of Argentina—were hardly self-professed Darwinians. Still, we have chosen to discuss them because of this last fact, and not despite it. As for da Cunha, though he accepted the basic canons of the new evolutionary theory, he remained ambivalent about its application. All three struggled, each in his own way, to come to terms with the Darwinian legacy, and each found his thinking profoundly shaped by this struggle; they offer us three different, unique perspectives on the impact of Darwinism. The magnitude of the new evolutionism can only be understood if we consider the wide range of discussion it triggered in consequence of its profound philosophical impact. (shrink)

This paper examines how the 19th-century British naturalist Alfred Russel Wallace used biogeographical mapping practices to draw a boundary line between Malay and Papuan groups in the colonial East Indies in the 1850s. Instead of looking for a continuous gradient of variation between Malays and Papuans, Wallace chose to look for a sharp discontinuity between them. While Wallace's "human biogeography" paralleled his similar project to map plant and animal distributions in the same region, he invoked distinctive "mental and moral" (...) features as more decisive than physical ones. By following Wallace in the field, we can see his field mapping practices in action -- how he conquered the problem of local particularity in the case of human variation. His experiences on the periphery of expanding European empires, far from metropolitan centers, shaped Wallace's observations in the field. Taking his cues from colonial racial categories and his experiences collaborating with local people in the field, Wallace constructed the boundary line between the Malay and Papuan races during several years of work in the field criss-crossing the archipelago as a scientific collector. This effort to map a boundary line in the field was a bold example of using the practices of survey science to raise the status of field work by combining fact gathering with higher-level generalizing, although the response back in the metropole was less than enthusiastic. Upon his return to Britain in the 1860s, Wallace found that appreciation for observational facts he had gathered in the field was not accompanied by agreement with his theoretical interpretations and methods for doing human biogeography.

The publication of Darwin's On the Origin of Species in 1859 ignited a public storm he neither wanted nor enjoyed. Having offered his book as a contribution to science, Darwin discovered to his dismay that it was received as an affront by many scientists and as a sacrilege by clergy and Christian citizens. To answer the criticism that his theory was a theory only, and a wild one at that, he published two volumes in 1868 to demonstrate that evolution was (...) obvious to anyone who cared to look at a bull in a pasture or a dog on a hearth. In response to those who insisted that species were distinct since creation, Darwin pointed to breeders of pigs and pigeons. In reply to those who protested that human intervention is one thing and natural selection another, he argued, "If organic beings had not possessed an inherent tendency to vary, man could have done nothing." To counter those who scorned his descriptions of species in exotic places, he submitted local evidence of cabbages and cauliflower. Based on a wide array of sources, from ancient pictographs to Polish roosters, from skins and from skeletons, from scientific journals and breeding manuals, Darwin assembled a mass of proof--and a hypothesis about species reversion that risked his reputation anew. The Variation of Animals and Plants under Domestication is a two-volume compilation of his thorough and intensive research and the revolutionary conclusions that resulted. The first portion of his work is dedicated to a meticulous analysis of various aspects of plant and animal life, including an inventory of varieties and their physical and behavioral characteristics, investigation of the impact of a species' surrounding environment and the role that both natural and forced changes in this environment have had. Darwin then turns to a richly detailed discussion of the roles of inheritance and crossing in the development of species. A wealth of illustrations further support and enhance his findings. This fascinating, invaluable, and courageous undertaking eventually formed the foundation for our current understanding of evolution. "In science as in politics the victors tend to write the history books. As a result, the record of the past is edited, intentionally or unintentionally, so that it focuses mainly on the precursors of contemporary orthodoxy. Such a focus may accurately represent the genealogy of modern ideas, but it almost inevitably misrepresents the historical experience of their progenitors... Even the powerful, persuasive, and ultimately triumphant theory of evolution by natural selection required not only defense, but repeated buttressing and revision. Variation showed Darwin hard at work on this rearguard action, using the materials he had at hand... His information was gleaned from the observations of fanciers, breeders, and amateur naturalists, as well as from the treatises of those on the cutting edge of zoology and botany. As hindsight narrows the historical spotlight, it imposes its own sense of hierarchy on the preoccupations of the past. But Darwin was interested in all of these topics, valued all of these sources, and belonged, to a greater or lesser extent, to all of these communities."--from the Introduction. (shrink)

Continuists maintain that, aside from their distinct temporal orientations, episodic memory and future-oriented mental time travel (FMTT) are qualitatively continuous. Discontinuists deny this, arguing that, in addition to their distinct temporal orientations, there are qualitative metaphysical or epistemological differences between episodic memory and FMTT. This chapter defends continuism by responding both to arguments for metaphysical discontinuism, based on alleged discontinuities between episodic memory and FMTT at the causal, intentional, and phenomenological levels, and to arguments for epistemological discontinuism, based on alleged (...) discontinuities with respect to the epistemic openness of the past and future, the directness or indirectness of our knowledge of past and future, and immunity to error through misidentification. The chapter concludes by sketching a positive argument for continuism. (shrink)

Philosophical theorizing is often, either tacitly or explicitly, guided by intuitions about cases. Theories that accord with our intuitions are generally considered to be prima facie better than those that do not. However, recent empirical work has suggested that philosophically significant intuitions are variable and unstable in a number of ways. This variability of intuitions has led naturalistically inclined philosophers to disparage the practice of relying on intuitions for doing philosophy in general (e.g. Stich & Weinberg 2001) and for doing (...) moral philosophy in particular (Appiah 2008; Doris & Stich 2005; Horowitz 1998; Nadelhoffer & Feltz 2008; Sinnott Armstrong 2008). In this paper, we will draw on naturalistic considerations to offer some solace to philosophers who rely on intuitions. We wouldn’t call this a defense of intuitions, exactly, since we are sympathetic with much of the naturalists’ critique. But we want to introduce into the debate some neglected naturalistic reasons to be optimistic about intuitions, focusing especially on ethical intuitions. (shrink)

In this groundbreaking book, Andrea R. English challenges common assumptions by arguing that discontinuous experiences, such as uncertainty and struggle, are essential to the learning process. To make this argument, Dr. English draws from the works of two seminal thinkers in philosophy of education - nineteenth-century German philosopher J. F. Herbart and American Pragmatist John Dewey. English's analysis considers Herbart's influence on Dewey, inverting the accepted interpretation of Dewey's thought as a dramatic break from modern European understandings of education.

Are they needed? To be sure. The Darwinian industry, industrious though it is, has failed to provide texts of more than a handful of Darwin's books. If you want to know what Darwin said about barnacles (still an essential reference to cirripedists, apart from any historical importance) you are forced to search shelves, or wait while someone does it for you; some have been in print for a century; various reprints have appeared and since vanished." -Eric Korn,Times Literary Supplement Charles (...) Robert Darwin (1880-1882) has been widely recognized since his own time as one of the most influential writers in the history of Western thought. His books were widely read by specialists and the general public, and his influence had been extended by almost continuous public debate over the last 130 years. New York University Press' edition makes it possible for the first time to review Darwin's public literary output as a whole, plus his scientific journal articles, his private notebooks, and his correspondence. This is the first complete edition containing all of Darwin's published books, featuring definitive texts recording original paginations with Darwin's indexes retained. All illustrations and plates are presented, inclucing 82 color plates of birds and mammals and several folding maps and plates. The set also features a general introduction and index, and textural introductions in each volume. (shrink)

Undoubtedly, the topic of discontinuity has got to an extent where it has captured the attention of a good number of researchers. These researchers devote themselves to reflect on the philosophy of the French thinker. Focusing on discontinuity promises to open a new line of analysis that, perhaps, will allow the revaluation of its scope in relation to its philosophical contributions. For such a task, first, we will approach the notion of history in Foucauldian thought to study the development this (...) notion has with the discontinuity; followed by a study of the archaeological method to unravel whether it is possible to analyze discontinuity through an archaeological view. Would it be possible to look at the topic of discontinuity as a characteristic feature of this French philosopher's thinking? This document aims to answer this question. (shrink)

The more interest philosophers take in memory, the less agreement there is that memory exists—or more precisely, that remembering is a distinct psychological kind or mental state. Concerns about memory’s distinctiveness are triggered by observations of its similarity to imagination. The ensuing debate is cast as one between discontinuism and continuism. The landscape of debate is set such that any extensive engagement with empirical research into episodic memory places one on the side of continuism. Discontinuists concerns are portrayed as almost (...) exclusively conceptual and a priori. As philosophers of memory become increasingly interested in memory science, this pushes continuism into an apparent lead. The aim of this paper is to challenge this characterization of the continuism debate—namely, that a naturalistic approach to the philosophy of mind and memory favors continuism. My response has two components. First, I argue for weakening the alignment between naturalism and continuism. Second, I defend a naturalistically oriented, empirically-informed discontinuism between memory and imagination. I do so by introducing seeming to remember, which I argue is distinct from other mental attitudes—most importantly, from imagining. (shrink)

Hume? Yes, David Hume, that's who Jerry Fodor looks to for help in advancing our understanding of the mind. Fodor claims his Treatise of Human Nature as the foundational document of cognitive science: it launched the project of constructing an empirical psychology on the basis of a representational theory of mind. Going back to this work after more than 250 years we find that Hume is remarkably perceptive about the components and structure that a theory of mind requires. Careful study (...) of the Treatise helps us to see what's amiss with much twentieth-century philosophy of mind, and to get on the right track. Hume says in the Treatise that his main project is to construct a theory of human nature and, in particular, a theory of the mind. Hume Variations examines his account of cognition and how it is grounded in his 'theory of ideas'. Fodor discusses such key topics as the distinction between 'simple' and 'complex' ideas, the thesis that an idea is some kind of picture, and the roles that 'association' and 'imagination' play in cognitive processes. He argues that the theory of ideas, as Hume develops it, is both historically and ideologically continuous with the representational theory of mind as it is now widely endorsed by cognitive scientists. This view of Hume is explicitly opposed to recent discussions by critics who hold that the theory of ideas is the Achilles heel of his philosophy and that he would surely have abandoned it if only he had read Wittgenstein carefully.You don't have to know much about Hume to enjoy this inventively argued, provocative, and stimulating defence of the representational theory of mind--which is looking increasingly hard to resist.LINES OF THOUGHTPhilosophy books don't need to be hundreds of pages long to make a substantial contribution to the subject.

In evolutionary biology, niche construction is sometimes described as a genuine evolutionary process whereby organisms, through their activities and regulatory mechanisms, modify their environment such as to steer their own evolutionary trajectory, and that of other species. There is ongoing debate, however, on the extent to which niche construction ought to be considered a bona fide evolutionary force, on a par with natural selection. Recent formulations of the variational free-energy principle as applied to the life sciences describe the properties of (...) living systems, and their selection in evolution, in terms of variational inference. We argue that niche construction can be described using a variational approach. We propose new arguments to support the niche construction perspective, and to extend the variational approach to niche construction to current perspectives in various scientific fields. (shrink)
