The proximate/ultimate distinction in the multiple careers of Ernst Mayr

Ernst Mayr's distinction between “ultimate” and “proximate” causes is justly considered a major contribution to philosophy of biology. But how did Mayr come to this “philosophical” distinction, and what role did it play in his earlier “scientific” work? I address these issues by dividing Mayr's work into three careers or phases: 1) Mayr the naturalist/researcher, 2) Mayr the representative of and spokesman for evolutionary biology and systematics, and more recently 3) Mayr the historian and philosopher of biology. If we want to understand the role of the proximate/ultimate distinction in Mayr's more recent career as a philosopher and historian, then it helps to consider hisearlier use of the distinction, in the course of his research, and in his promotion of the professions of evolutionary biology and systematics. I believe that this approach would also shed light on some other important “philosophical” positions that Mayr has defended, including the distinction between “essentialism: and “population thinking.”     

Jules Cotard: sa vie, son œuvre

Jules Cotard was a psychiatrist at the Vanves asylum. Described as a sharp observer and clinician, he also had a passion for clinical research. Jules Cotard was always ready to modify, question, or even abandon a hypothesis if clinical facts and scientific analysis made him deem it necessary to do so. He devoted most of his writing to “negation delirium”, (also known as “nihilistic delusion”): “Du délire hypochondriaque dans une forme grave de mélancolie (“Concerning hypochondriac delusion in serious melancholy”)” in 1880, “Du délire des négations (“Concerning negation delirium”)” in 1882, “Perte de la vision mentale dans une mélancolie anxieuse (“Loss of mental vision in anxious melancholy”)” in 1884 and “Du délire d’énormité (“Concerning delusions of enormity”)” in 1888. Long after his death, there was much controversy and debate about the existence of negation delirium. J. Séglas and J. Régis were the main contributors to the development and clarification of his work. Thus it is this most unusual of syndromes, Cotard’s syndrome, that has caused Jules Cotard to be part of the history of French psychiatry since the end of the 19th century.     

Anatomy,metaphysics, and values: The ape brain debate reconsidered

Conventional wisdom teaches that Thomas Huxley discredited Richard Owen in their debate over ape and human brains. This paper reexamines the dispute and uses it as a test case for evaluating the metaphysical realist, internal realist, and social constructivist theories of scientific knowledge. Since Owen worked in the Kantian tradition, his anatomical research illustrates the implications of internal realism for scientific practice. As an avowed Cartesian, Huxley offered a well developed attack on Owen's position from a metaphysical realist perspective. Adrian Desmond's political retrospective on the dispute affords the additional opportunity to contrast internal realism with social constructivism. I argue that since Huxley ultimately based his attack on his valuing Europeans as superior to blacks, his argument illustrates the hazards of accepting the metaphysical realist promise of value free science. Desmond overlooks this racial dimension of the dispute, and his work shows how social constructivism can distract the historian and philosopher from even the social meaning of science. As internal realists like Putnam have argued, values enter science not from without, but from within the very process of science itself.     

Willi Hennig’s dichotomization of nature

Two formal assumptions implied in Willi Hennig’s “phylogenetic systematics” were repeatedly criticized for not being biologically grounded. The first is that speciation is always dichotomous; the second is that the stem‐species always goes extinct when its lineage splits into two daughter species. This paper traces the theoretical roots of Hennig’s “principle of dichotomy”. While often considered merely a methodological principle, Hennig’s realist perspective required him to ground the “principle of dichotomy” ontologically in speciation. As a methodological principle, the adherence to a strictly dichotomously structured phylogenetic system allowed Hennig to be unequivocal in character analysis and precise in the rendition of phylogenetic relationships. The ontological grounding of the “principle of dichotomy” in speciation remains controversial, however. This has implications for the application of techniques of phylogeny reconstruction to populations of bisexually reproducing organisms (phylogeography). Beyond that, the “principle of dichotomy” has triggered an intensive debate with respect to phylogeny reconstruction at the prokaryote level. © The Willi Hennig Society 2010.     

Reflections on the meanings of dreams prompted by reading Stekel.

What does it mean to interpret a dream? While reading Stekel, an underappreciated but fascinating author, I was struck both by his keen insights as well as his interpretive limitations. This led to broader questions concerning the polyvocal concept of “meaning” in the interpretation of dreams. This article suggests the meaning of dreams can include wish fulfillments, univocal translations, clarifying the life context, morphological equivalences, associations, and personal history. Stepping back, even the question of “interpretation” versus “appreciation” reminds us that the need, if any, for interpretation will vary depending on who is asking the question. Indeed, reflections on the “who” or ego in the dream leads beyond dreaming to ultimate questions concerning the reality of ego and meditative reflections on what it means to truly be awake and aware of life as it is.

Mystery of mysteries: Darwin and the species problem

Darwin offered an intriguing answer to the species problem. He doubted the existence of the species category as a real category in nature, but he did not doubt the existence of those taxa called “species”. And despite his scepticism of the species category, Darwin continued using the word “species”. Many have said that Darwin did not understand the nature of species. Yet his answer to the species problem is both theoretically sound and practical. On the theoretical side, Darwin’s answer is confirmed by contemporary biology, and it offers a more satisfactory answer to the species problem than recent attempts to save the species category. On the practical side, Darwin’s answer frees us from the search for the correct theoretical definition of “species”. But at the same time it does not require that we banish the word “species” from biology as some recent sceptics of the species category advocate. © The Willi Hennig Society 2010.     

Piercing transfigurations: Representations of suffering in Cyprus

This paper explores representations of suffering in Cyprus, a divided island. It examines differences between Greek and Turkish Cypriots in their official publicity/propaganda photographic material in representing the issue of missing persons in Cyprus. It attempts to show that the differences are relatable not just to their different persuasive strategies, but also to different approaches to photography, to experience and memory. For the Greek Cypriots, the sacrifice of the person has to be represented as an absent body, the quintessential example being Christ. By contrast, for the Turkish Cypriots it is the presence of a (dead) body, the body of the dead hero/fighter, that signifies a sacrifice and transforms him into a shehit (martyr). Such differences can be related to differences between the two groups in the political fabulation of the past and its appeal to “memory” and “experience”. The Turkish Cypriots because of their pressing political problems, especially between 1963–70 when they tended to view their survival as being at stake, use photographs in a relatively “realist” matter‐of‐fact way although their aim is highly emotionally charged. Greek Cypriots use photographs as representations of what is in effect an iconic predicament: representation as participating in some fundamental way in that which it represents. After examining the predicament of depicting suffering through photography, the paper suggests that to respond effectively to suffering we may have to approach it not through the seductive realism of the photograph but through its means of representing the symbolic and the imaginary.     

Mental Health: The Search for a Definition

Various attempts to define the concept of “mental health” are examined. Value judgments permeate much mental health literature. Their use militates against obtaining an objective definition, capable of universal application. The acceptance of a definition including a value judgment implies taking an attitude toward a particular society and its social ideals.Present limits of competence only allow us to describe “mental health” conceptually. Such “untechnical” proposals are liable to be confused with “technical” (“scientific”) propositions. Multiple criteria are likely to be helpful in improving our concept of “mental health”.The intrusion of morals into the world of health is discussed as part of the contemporary intellectual dilemma of determined human behaviour versus human responsibility and the reality of moral values.It is suggested that “mental health” might consist simply of an individual''s possession of insight into his own personality, combined with an honest recognition and acceptance of his condition.     

My View on the“Quan Fang Bei Zu”

“Quan Fang Bei Zu” is a compiled work mainly for folklores, poems and other literary works concerning some common plants with some botanical information in it. It is certainly not a pure botanical work, covering no more than 240 species of plants, and thus has little use as a reference book in indexing names even in a primitive sense. Therefore “Quan Fang Bei Zu” could not be considered as a botanical dictionary. Xu Wen-xuan and his co-workers’ argument that “Quan Fang Bei Zu” was the most perfect ancient botanical codes and records till then is not convincing. Actually “Tu Jing Ben Cao” is of higher value than the book under discussion from botanical point of view.     

Connecting domination contracts

In Black Rights/White Wrongs, Charles Mills continues his critique of contemporary American political philosophy for ignoring issues of racial oppression, and in particular for ignoring the way that liberal social contracts rest on underlying domination contracts. In this commentary, I will discuss some of the new research inspired by Mills’ account of domination contracts, including recent accounts of the “capability contract” and the “species contract”, and explore how they relate to Mills’ own work on the “racial contract”. While this new research on diverse domination contracts confirms the richness of Mills’ analysis of the social contract tradition, it may also require some revisions to his own preferred vision of how we theorize racial justice.     

150 Jahre “Biogenetisches Grundgesetz”

150 years “Biogenetic Law” The zoologist Ernst Haeckel is one of the most well‐known, but also one of the most controversial scientists of the late 19th and early 20th centuries. He was one of the earliest Darwinists and a forceful advocate of evolutionary theory. Together with “Darwin's Bulldog” Thomas Henry Huxley, Haeckel was a central figure in the early history and popularization of Darwinism. But his name is not only a symbol for the disputes about the theory of evolution and its popularization, but also for a campaign for monism, a world‐view or philosophy created by Haeckel himself. Together with Fritz Müller, Ernst Haeckel was one of the first to formulate a “Biogenetic Law”. He also created several concepts and terms still in use in biology today, such as “ontogeny”, “phylogeny”, “ecology”, “cholorogy” and “phylum” in his first, and maybe most important book “General Morphology of Organism”, which was published in 1866, 150 years ago.     

Malice's wonderland: Research funding and peer review

The players all played at once, without waiting for turns, quarreling all the while and fighting for the hedgehogs; and in a very short time the queen was in a furious passion and went stamping about, and shouting “off with his head” or “off with her head,” about once a minute. Alice began to feel very uneasy: to be sure she had not as yet had any dispute with the queen, but she knew that it might happen any minute, “and then” thought she, “what would become of me? They're dreadfully fond of beheading people here: the great wonder is, that there's any one left alive”.     

Recent trends in evolutionary ethics: greenbeards!

In recent years, there has been growing awareness among evolutionary ethicists that systems of cooperation based upon “weak” reciprocity mechanisms (such as tit-for-tat) lack scalability, and are therefore inadequate to explain human ultrasociality. This has produced a shift toward models that strengthen the cooperative mechanism, by adding various forms of commitment or punishment. Unfortunately, the most prominent versions of this hypothesis wind up positing a discredited mechanism as the basis of human ultrasociality, viz. a “greenbeard.” This paper begins by explaining what a greenbeard is, and why evolutionary theorists are doubtful that such a mechanism could play a significant role in explaining human prosociality. It goes on to analyze several recent philosophical works in evolutionary ethics, in order to show how the suggestion that morality acts as a commitment device tacitly relies upon a greenbeard mechanism to explain human cooperation. It concludes by showing how some early scientific models in the “evolution of cooperation” literature, which introduced punishment as a device to enhance cooperation, also tacitly relied upon a greenbeard mechanism.     

Distastefulness as a defense mechanism in Aplysia brasiliana (Mollusca: Gastropoda)

An unusual courtship pattern for fiddler crabs is described from field observations in Panama. This behavior pattern, referred to here as “directing,” differs considerably from the more frequently observed communal courtship system found in close relatives of Uca deichmanni. A male involved in “directing” approaches a female and attempts to carry or maneuver her into his burrow for mating. The female usually struggles to escape from the male. This activity often attracts other males which attempt to “direct” the female if she escapes from the first male. A male is most successful in “directing” a female into his burrow if a) he is larger than the female, b) the female is wandering (a sign of physiological receptivity) prior to the “directing” attempt, and c) several males attempt to “direct” the female at once. The results suggest that females are choosing mates by inciting several males to compete for them. The males which successfully “direct” the struggling females are probably the most fit males.     

Developing a readiness self-assessment tool for low- and middle-income countries establishing new radiotherapy services: A participant validation study

PurposeAssessing low-and middle-income countries’ (LMICs’) readiness to establish new radiotherapy services is an important but empirically understudied concept. The purpose of this study is to develop and confirm a core set of readiness requirements and criteria that can be used to gauge LMICs preparedness to establish radiotherapy services.MethodsBased on a systematic review and semi-structured expert interviews, a pool of requirements and criteria were generated. To confirm or disconfirm these items, we adopted a synthesised member checking process, also known as participant validation. A purposive sampling strategy was used to recruit radiotherapy experts. Items were sent via email. Each item was reviewed by participants. Qualitative comments were analysed thematically.FindingsSeven of the 17 experts who participated in an earlier semi-structured interview contributed to this participant validation study. The final version of the readiness self-assessment tool for LMICs establishing new radiotherapy services contains 37 requirements mapped into four readiness domains, grouped under the following categories: commitment; cooperation; capacity; and catalyst. Among 23 criteria for commitment domain, participants reviewed 22 as relevant for inclusion. The cooperation requirements considered important, included: “strategic planning team”, “stakeholder involvement” and a “technical assistance plan”. Capacity requirements, which were endorsed included: “responsible project manager”; “availability of radiotherapy expertise”; and “training for initial core staff”. Participants’ feedbacks supported the inclusion of all the requirements and criteria related to catalyst.ConclusionThe readiness self-assessment tool is a promising planning and evaluation tool for use by stakeholders interested in expanding access to radiotherapy services in LMICs.     

The Identity of La Salle’S Pana Slave

Abstract

In June 1682 Robert Cavelier, Sieur de La Salle, was presented with a “Pana” boy by the Illinois Michigamea Indians. The boy told La Salle of his history as a captive in four Indian tribes. He described Indian village locations and listed the tribes which had “many” horses. The significance of the information for which he was the source depends on the tribal identity of the captive. It has been suggested in anthropological literature that “Pana” indicated “Pawnee,” Ponca, Arikara, Wichita, even Apache. After examination of evidence-linguistic, cultural, historical - it seems most likely he was a Southern Pawnee, a Wichita. If this was so, then his information substantiates the theory of Kroeber, Brant and others that some Kiowa Apaches were still living in the southern Plains in the late 17th century.     

Beyond the DP/DSS controversy

Paul Turke's “Which humans behave adaptively, and why does it matter?” shows, if he we are to take him as being representative of “Darwinian social science” in general, that his school of thought has moved surprisingly close to that of its “Darwinian psychology” critics in accepting the importance if not the primacy of the psychological level of explanation in applying evolutionary theory to human behavior. Disagreements continue over whether the adaptiveness of current behavior should be viewed as an occasionally interesting question because of the light it can shed on evolved psychological mechanisms, or whether, as Turke maintains, it is the central question for human sociobiology. In any event, the “vertically integrated approach,” utterly ignored by Turke, incorporates Darwinian Psychology and is far more powerful than is Turke's approach in explicating the relationship between genes and culture, thereby rendering the current debate pointless.     

IsSchindewolf’s “Grundfragen der Paläontologie” still worth reading? An apologetic evaluation of his work

Roughly five years ago O.H. Schindewolf’s book “Grundfragender Paläontologie” was first published in English by the University of Chicago Press, about fifty years after the original German edition. Thus, for the first time a considerable number of English-speaking palaeontologists became acquainted with the author’s ideas of the evolutionary process. Inevitably, numerous book reviews followed, introducing “the new publication’. The predominant tenor is characterized by titels like “Magnificent wrongheadedness” or “Wonderfully, gloriously wrong”. By referring to recent results in developmental genetics and population ecology it is shown that Schindewolf’s ideas concerning the progress of evolution must by no means be interpreted simply as a product of a self reverential, wrongheaded spirit, preformed by the atmosphere of German romanticism. Truly, his ideas can be understood as the result of a scientific imagination which was not preoccupied by neo-Darwinian paradigms and was ahead of the biological knowledge of his time.
