This paper presents an analysis of Seneca's 58th letter to Lucilius and Porphyry's Isagoge, which were the origin of the tree diagrams that became popular in philosophy and logic from the early Middle Ages onwards. These diagrams visualise the extent to which a concept can be understood as a category, genus, species or individual and what the method of dihairesis (division) means. The paper explores the dissimilarities between Seneca's and Porphyry's tree structures, scrutinising them through the (...) perspective of modern graph theory. Although traditional trees can be interpreted in a modern way, their terms and definitions defy modern standardisation. These distinctions are not only useful for differentiating between Seneca's and Porphyry's trees, but also for comprehending the evolution of this philosophical tradition. Thus the paper highlights the continued significance of these tree diagrams in analysing concepts and categories in philosophy and structuring objects and information in modern fields such as artificial intelligence, computer science, bioinformatics, graph theory, and many more.

On the Cave of the Nymphs, an allegorical exegesis of Homer’s description of the cave of the nymphs at Odyssey 13.102-112, a passage quoted in full at the beginning of the treatise after the briefest possible indication of the project on which Porphyry is embarking, has been generally given little attention in discussions of Neoplatonic philosophy, as it is deemed to be of little importance for establishing Porphyrian doctrine. However, the treatise contains significant philosophical thoughts on the relationship between (...) the soul and body, embodiment, demonology, and the concept of the salvation of the soul, which are compatible with his other works, especially _On Abstinence from Killing Animals_ and _Pathways to the Intelligible_. The concept of the salvation of the soul is found in Porphyry’s identification of the goddess Athena with _phronesis_, along with the olive tree, while Odysseus represents the soul descending into genesis, but will return back to his fatherland. In this context, this paper will explore the role and meaning of _phronesis_, namely the goddess Athena, in the process of the soul’s journey towards the intelligible realm and show the relevance of the Neoplatonic doctrine of virtues, particularly the cathartic virtues, in _Sententia_ 32 to Porphyry’s reading of Homer’s image of Odysseus under guidance of the goddess Athena. _Phronesis_ inspires the soul to incline towards the level of Intellect that is, away from damaging influences of the body to which the soul is enslaved and which confuses it with desires, passions, fears and illusory impressions, and prevents it from attaining the intelligible realm, whereas the body and its desires lead us to conflict and unjust behaviour in order to gain wealth, status, power, and pleasure.

Cet article met en question une tendance postmoderne assez répandue: celle de reconstruire abusivement la signification d’un texte du passé, de telle façon que ce texte puisse jouer le rôle d’allié ou d’ennemi dans nos guerres idéologiques. L’exemple choisi c’est un article d’Umberto Eco - «Anti-Porfirio» ainsi qu’un chapitre parallèle de son livre Semiotics and the Philosophy of Language. Selon Eco, le fameux «Arbre de Porphyre» serait une illustration graphique de ce qu’il appelle «pensée forte». Or, cette pensée aurait été (...) minée depuis longtemps - affirme Eco - par la «pensée faible» qu’il retrouve dans la soi-disant «pensée encyclopédique», et ce sont déjà certains textes d’Aristote ou de Thomas d’Aquin, qui en attestent la présence. De plus, Eco pense avoir trouvé dans le Discours préliminaire d’Alembert, oeuvre qui préface l’Encyclopédie française, un devancier de la «pensée faible» postmoderne. Il s’apparente, selon lui, au «rhizome» décrit par G. Deleuze. Aussi cette «pensée encyclopédique» est-elle l’opposé même de la logique incarnée par l’antique «Arbre de Porphyre». L’article tâche de montrer qu’Umberto Eco a beaucoup déformé certaines idées des philosophes mentionnés là-dessus. En effet, il a tendance à discuter les textes pertinents hors de leur contexte métaphysique originaire, tout en en omettant certains aspects décisifs. D’après Eco, Thomas d’Aquin et surtout d’Alembert auraient anticipé le postmodernisme, ce qui, selon moi, n’est pas du tout le cas. Je crois que, en effet, Eco a donné moins une description tant soit peu fidèle d’un passé philosophique qu’une reconstruction relativement abusive de ce passé, légitimant ainsi ses propres vues philosophiques.

Interest in philosophical anthropology in the early twelfth century was limited to the logical question of how to think and speak about dead humans. This question was prompted by the logic of living and dead humans based on the doctrine of substance found in Aristotle’s Categories and in the division of substance, as outlined by Porphyry to exemplify the logic of genus and species relations in the Isagoge. Abelard held the view that there is no such thing as a (...) dead human, and this provoked an intense response from his contemporaries. Abelard’s contemporaries, including Alberic of Paris and other anonymous authors, mounted a number of arguments against Abelard’s views. The stakes were high for them: as realists about species and genera, Abelard’s denial that there are dead humans threatened their entire interpretation of the structure of species and genera, and thereby their theory of universals.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Cambridge History of Philosophy in Late AntiquityJohn RistLloyd P. Gerson, editor. The Cambridge History of Philosophy in Late Antiquity. 2 vols. Cambridge-New York: Cambridge University Press, 2010. Pp. 1313. Cloth, $240.00.1313 pages, including 915 pages of text and 200 of bibliography; 51 authors—in about 800 words! The editor of the present Cambridge History makes plain that his new two-volume monument is the successor to Armstrong’s Cambridge History (...) of Late Greek and Early Medieval Philosophy—8 contributors—and is intended to build on its strengths and correct its deficiencies in the light of some 40 years of highly successful investigation of the thought of late antiquity. The result is a professional structure in which the “giants” (Plotinus and Augustine) are awarded comparatively modest coverage, while figures often neglected, such as Damascius, of whom our understanding has greatly increased of late, are given much more space. Damascius secures 30 pages: the only individual to get more is Porphyry (33), while Augustine has 29 and Plotinus 24 (four more than Hierocles). There are those (as Tacitus might have put it) who will fear that the wood has been lost for the trees, and at least it must be said that one overall impression of these volumes is that some of their authors are recounting what will be of interest to a worldwide group of aficionados whose number can be counted on the fingers of a mutilated hand—and the importance of which lies less in philosophical achievement than in the handing on of a great tradition.Gilbert Ryle is supposed to have asserted that in France everyone can talk about philosophy but that there are no philosophers; some of Gerson’s more philosophically minded readers may find their prejudices confirmed that in late antiquity there were many who talked about Plato and Aristotle but few who understood what they were trying to do. For it is clear that a general theme of the present volumes is that in late antiquity philosophers were largely concerned to “interpret” Plato and (especially after Porphyry) Aristotle while occasionally seizing the opportunity not merely to rubbish their similarly-engaged predecessors but to add (if shamefacedly) something of their own. Except, that is, for the Christians, whose enterprise was very different and who, quite properly, are more visible in Gerson’s account of late antique thought than in that of Armstrong (though there remain strange omissions in a work on this scale: Methodius, Ambrose, Evagrius).Gerson has tried to contextualize his story by including short (and helpful) historical introductions by Elizabeth DePalma Digeser to the various epochs with which his volumes are concerned, and which can perhaps be divided into four sections: pre-Plotinian Platonism [End Page 136] (plus extras) from Cicero to Numenius; later pagan Platonism, including extensive treatment of the Neoplatonic commentators on Aristotle; Christian thought before Constantine; and later Christian philosophy-cum-theology. Rounding off the volume are introductions to the transition from “ancient” to “medieval” thought in the Latin West (Gersh), in Byzantium—a remarkably honest presentation of a largely stagnant philosophical world by Ierodiakonou and Zografidis—and (in a magisterial improvement on what is to be found in Armstrong) in Islam (Cristina d’Ancona) where (inter multa alia) the roots of the virtually inevitable later destruction of a flourishing philosophical tradition founded by al-Kindi and al-Farabi are identified in the more “orthodox” and theocratic approach—here there are Byzantine parallels—of the followers of al-Ash’ari (885).Gerson’s readers can inspect philosophical wisdom and conceptual muddle among late antique intellectuals—Christians, a few Muslims, pagans—down to Scotus Eriugena and al-Farabi. But some of them may suspect that an opportunity has been lost to reflect on the origins and nature of early Christian thought, and to ask why Christians soon jumped for Platonism rather than Stoicism (Aristotle, let alone Epicurus, was not—yet—considered a serious option)—and that is not intended as criticism of the excellent, if brief, treatment of important Christian thinkers such as Origen. But it was an adventure for Christians to begin to philosophize, and when they embarked on this adventure—here the significance... (shrink)

The series is devoted to the study of scientific and philosophical texts from the Classical and the Islamic world handed down in Arabic. Through critical text editions and monographs, it provides access to ancient scientific inquiry as it developed in a continuous tradition from Antiquity to the modern period. All editions are accompanied by translations and philological and explanatory notes.

In his major work, the Periphyseon, the ninth century Latin philosopher John Scottus Eriugena gives, with the help of what he calls "dialectic", a rational analysis of reality. According to him, dialectic is a science which pertains both to language and reality. Eriugena grounds this position in a realist ontological exegesis of the Aristotelian categories, which are conceived as categories of being. His interpretation tends to transform logical patterns, such as Porphyry's Tree or the doctrine of the categories, (...) into a structure which is both ontological and logical, and to use them as tools for the analysis of the sensible world. The combination of dialectic interpreted as a science of being, capable of expressing truths about the sensible world as well as about discourse, with an ontological interpretation of logical concepts allows Eriugena to develop his metaphysical theory, a strong realism. Eriugena not only supports a theological realism, but also, and principally, an ontological realism, the assertion of the immanent existence of forms. Eriugena claims that genera and species really subsist in the individuals: they are completely and simultaneously present in each of the entities which belong to them. (shrink)

A key figure in the history of Aristotelianism, Porphyry (AD 232/3 - c. 305) was born in Tyre and was a student of Longinus' in Athens and of Plotinus' in Rome. In his commentary on the Categories, Porphyry provided an authoritative interpretation of a notoriously controversial work. Commentators on Aristotle had disagreed fundamentally over whether the Categories was a work of logic, concerning simple terms or the simple concepts they represent, or a metaphysical work addressing the classification by (...) genera of simple entities or concepts. Approaching the Categories as the first of Aristotle's works in logic, Porphyry adopted an earlier Peripatetic view of the Categories as being concerned principally with terms or linguistic items, which he calls "predicates." He successfully defended the Categories against Plotinus, arguing that while it seemed to attack orthodox Platonism by denying the separation of forms and the ontological priority of the universal, it was in fact entirely compatible with Platonism. Because of Porphyry's intervention, the Categories came to serve as a basic textbook of logic for subsequent Neoplatonist teaching. His commentary influenced the Arabic tradition, and Boethius drew heavily on it as well. The full text of Porphyry's commentary was lost, but the extant version is available here in Steven K. Strange's new translation. Ancient philosophers, historians of philosophy, classicists, and medievalists will welcome its appearance in English. (shrink)

Abstract: Biology continues to use the Tree of Life image to show the temporal continuity and discontinuity of the living beings. Moreover, the development of genetic, molecular biology and paleontology has originated phylogenetics. This discipline studies evolutionary relatedness among various groups of organisms through molecular sequencing data and morphological data matrices. The Tree offers interesting points for semiotic perspectives and for theological approaches too. The symbolic reading of the Tree of Life, on the one hand, and the (...) analogies with the Biblical genealogies and some Christian images, on the other hand, will be explored. -/- . (shrink)

The ‘Tree of Life’ is intended to represent the pattern of evolutionary processes that result in bifurcating species lineages. Often justified in reference to Darwin’s discussions of trees, the Tree of Life has run up against numerous challenges especially in regard to prokaryote evolution. This special issue examines scientific, historical and philosophical aspects of debates about the Tree of Life, with the aim of turning these criticisms towards a reconstruction of prokaryote phylogeny and even some aspects of (...) the standard evolutionary understanding of eukaryotes. These discussions have arisen out of a multidisciplinary collaboration of people with an interest in the Tree of Life, and we suggest that this sort of focused engagement enables a practical understanding of the relationships between biology, philosophy and history.

Makkai [10] produced an arithmetical structure of Scott rank $\omega _{1}^{\mathit{CK}}$. In [9]. Makkai's example is made computable. Here we show that there are computable trees of Scott rank $\omega _{1}^{\mathit{CK}}$. We introduce a notion of "rank homogeneity". In rank homogeneous trees, orbits of tuples can be understood relatively easily. By using these trees, we avoid the need to pass to the more complicated "group trees" of [10] and [9]. Using the same kind of trees, we obtain one of rank (...) $\omega _{1}^{\mathit{CK}}$ that is "strongly computably approximable". We also develop some technology that may yield further results of this kind. (shrink)

One of his six introductions to philosophy, widely used by students in Alexandria, Ammonius' lecture on Porphyry was recorded in writing by his students in the commentary translated here. Along with five other types of introductions (three of which are translated in the Ancient Commentators on Aristotle volume Elias and David: Introductions to Philosophy with Olympiodorus: Introduction to Logic) it made Greek philosophy more accessible to other cultures. These introductions became standard in Ammonius' school and included a popular set (...) of five or more definitions of philosophy, some of them drawn from commentaries on quite different works. Ammonius' lecture expounded the most celebrated and discussed previous introduction written by Porphyry 200 years earlier, which was devoted to five main technical terms of Aristotle's logic. Ammonius was sympathetic to Porphyry because they both sought to harmonise the views of Plato and Aristotle with each other, arguing in different ways that the two philosophers did not disagree about the nature of universals. Porphyry's introduction was a hugely influential work for centuries after its composition, and this commentary by Ammonius served to maintain its position at the centre of later schools of philosophy. This English translation of Ammonius' work is the latest volume in the Ancient Commentators on Aristotle series and makes this philosophical work accessible to a modern readership. The translation is accompanied by an introduction, comprehensive commentary notes, bibliography, glossary of translated terms and a subject index. (shrink)

"The Natural System" is the name given to the underlying arrangement present in the diversity of life. Unlike a classification, which is made up of classes and members, a system or arrangement is an integrated whole made up of connected parts. In the pre-evolutionary period a variety of forms were proposed for the Natural System, including maps, circles, stars, and abstract multidimensional objects. The trees sketched by Darwin in the 1830s should probably be considered the first genuine evolutionary diagrams of (...) the Natural System—the first genuine evolutionary trees. Darwin refined his image of the Natural System in the well-known evolutionary tree published in the Origin of Species, where he also carefully distinguished between arrangements and classifications. Following the publication of the Origin, there was a great burst of evolutionary tree building, but interest in trees declined substantially after 1900, only to be revived in recent years with the development of cladistic analysis. ¶ While evolutionary trees are modern diagrams of the Natural System, they are at the same time instances of another broad class of diagrams that may be called "trees of history": branching diagrams of genealogical descent and change. During the same years that Darwin was sketching his first evolutionary trees, the earliest examples of two other trees of history also appeared: the first trees of language evolution and of manuscript genealogy. Though these were apparently independent of evolutionary trees in their origin, the similarities among all these trees of history, and among the historical processes that underlie them, were soon recognized. Darwin compared biological evolution and language evolution several times in the Origin of Species, and both Ernst Haeckel and the linguist August Schleicher made similar comparisons. Both linguists and stemmaticists (students of manuscript descent) understood the principle of apomorphy—the principle that only shared innovations provide evidence of common ancestry—more clearly than did systematists, and if there had been more cross-fertilization among these fields the cladistic revolution in systematics might well have taken place in the nineteenth century. ¶ Although historical linguists and stemmaticists have in some respects had sounder theory than have systematists, at least until recently, they have also had the practical problem of very large amounts of data, a problem not often faced by systematists until the advent of molecular sequencing. The opportunity now exists for systematists to contribute to the theory and practice of linguistics and stemmatics, their sister disciplines in historical reconstruction, through application of our commonly used computer programs for tree estimation. Preliminary results from the application of numerical cladistic analysis to a large stemmatic data set have been very encouraging, and have already generated much discussion in the stemmatics community.

The canonical view of a 3‐domain (3D) tree of life was recently challenged by the discovery of Asgardarchaeota encoding eukaryote signature proteins (ESPs), which were treated as missing links of a 2‐domain (2D) tree. Here we revisit the debate. We discuss methodological limitations of building trees with alignment‐dependent approaches, which often fail to satisfactorily address the problem of ‘‘gaps.’’ In addition, most phylogenies are reconstructed unrooted, neglecting the power of direct rooting methods. Alignment‐free methodologies lift most difficulties but (...) require employing realistic evolutionary models. We argue that the discoveries of Asgards and ESPs, by themselves, do not rule out the 3D tree, which is strongly supported by comparative and evolutionary genomic analyses and vast genomic and biochemical superkingdom distinctions. Given uncertainties of retrodiction and interpretation difficulties, we conclude that the 3D view has not been falsified but instead has been strengthened by genomic analyses. In turn, the objections to the 2D model have not been lifted. The debate remains open. Also see the video abstract here: https://youtu.be/-6TBN0bubI8. (shrink)

138 titles across a wide range of scholarly publications illustrate the conceptual affinities that connect the palaetiological sciences of biological systematics, historical linguistics, and stemmatics. These three fields all have as their central objective the reconstruction of evolutionary "trees of history" that depict phylogenetic patterns of descent with modification among species, languages, and manuscripts. All three fields flourished in the nineteenth century, underwent parallel periods of quiescence in the early twentieth century, and in recent decades have seen widespread parallel revivals. (...) "Tree thinking" (O'Hara, 1988) is now standard within evolutionary biology, and the unity of what William Whewell called palaetiology is being once again appreciated by scholars and scientists in many fields.

To generate empathy in the care of vulnerable older persons requires care providers to reflect critically on their care practices. Ethics education and training must provide them with tools to accomplish such critical reflection. It must also create a pedagogical context in which good care can be taught and cultivated. The care-ethics lab ‘sTimul’ originated in 2008 in Flanders with the stimulation of ethical reflection in care providers and care providers in training as its main goal. Also in 2008, sTimul (...) commenced the organization of empathy sessions as an attempt to achieve this goal by simulation. The empathy session is a practical and fairly straightforward way of working to provoke care providers and care providers in training to engage in ethical reflection. Characteristic of the empathy session in the care-ethics lab is the emphasis on experience as a basis for ethical reflection. (shrink)

This paper delves into the intricate connections between the Abrahamic religions and the ancient mystery cults, reaching as far back as to Neolithic shamanism. They all unite in a shared pursuit: the quest for divine knowledge. Long before the Tree of Knowledge of Good and Evil in the biblical Genesis took on its profound symbolic meaning, shamanic initiation held a distinctly different view of botany. Indeed, It regarded plants primarily for their psychedelic properties, as a medium to perceive “reality” (...) with heightened intensity. However, the sacred Tree has a uniquely numinous character, and their consumption is sternly prohibited by God, in both, the Bible and the Quran. Therefore, this effectively positions all monotheistic religions in an unequivocal distance from their prehistoric origins. More precisely, we can argue that these mythologies are in fact constructed as counternarratives, advocating, primarily for a social ethic (based on the holy writings of the Bible), and evoking secondly a fundamental gnostic quest.

Viewing education through the prism of the Torah, Tree of Life, Tree of Knowledge takes the reader through the stages of learning, growth, and self-development that characterize human lives. The journey begins with education as it happens in the home, moves on to the institutions of society, especially schools, and then on to the questions of identity and commitment which constitute the hidden agenda of “informal educational networks.” The self-education of the individual is explored: When does one “grow (...) up”? What is really worth knowing? How does one cope with memories, illness, and anticipations of what lies ahead? This book examines some of the millennial conversation in an attempt to discover an educational philosophy in the Torah that can be relevant to life in the contemporary world. (shrink)

As a way forward in assessing how the Old Testament wisdom tradition might speak to decisions in a modern medical context, in this paper, I propose exploring the iconographic function of the “tree of life” in the Old Testament, which is consistently associated with both wisdom as well as life and health, in order to tease out two-related issues that can help in providing a Christian theological framework for thinking about the problem of the medicalization of risk: first, how (...) should the natural and good human desire for health and long life be framed in terms of the pursuit of wisdom? And, second, how might a sapientially formed character approach risk and uncertainty in making medical decisions? The answers to these questions help establish a framework in which more specific questions related to the medicalization of risk can be assessed. As such, this paper is deliberately programmatic and perspectival rather than prescriptive. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 27.2 (2003) 255-268 [Access article in PDF] The Tree of Knowledge and Darwinian Literary Study Jonathan Gottscha I THE BRANCHES OF KNOWLEDGE are not strewn randomly on the ground; they are part of a coherent, interconnected tree. Physics is the most fundamental of all the sciences, so it is the trunk of the tree. The branch of chemistry emerges from physics, because the (...) laws of chemistry depend on the laws of physics: chemical reactions occur the way they do because of the physical properties of atoms. Biology's branch splits off from chemistry's: the molecules that comprise living things are bound by the rules of chemistry. Scientists, while grasping this fundamental interconnection of the broad boughs of the natural sciences, 1 have rarely craned their necks sufficiently to glimpse the upper reaches of the tree of knowledge: the green canopy of human culture that is the traditional jurisdiction of the social sciences and humanities. In fact, scholars from all disciplines have mostly proceeded as though the greenery above was the outgrowth of a neighboring tree from a fundamentally different species.Since the 1960s, however, a maverick band of Darwinian neck-craners have been demonstrating that the stuff of human culture, studied in the humanities and social sciences, is a contiguous part of the tree of knowledge: human culture and behavior grow out of human biology. 2 These scholars and scientists continue to define themselves by different names depending on subtleties in their particular approaches: Darwinian psychology, sociobiology, Darwinian anthropology, biosociology, human behavioral ecology, human ethology, and evolutionary psychology. 3 However, sacrificing some precision on the alter of clarity, I will refer to all of the above approaches with the umbrella term of human [End Page 255] behavioral biology, understood in its most expansive sense as the study of how millions of years of evolution shaped the human mind, and thus human behavior, and thus human culture. No matter how human behavioral biologists define their work, they all share the conviction that human behavior, psychology, and culture cannot be fully understood separate from human bio-evolutionary history.Darwinian excavation of the foundations of human nature has inspired a revolutionary movement in the social sciences that proceeds to this day. Like most revolutions, this one has seen its share of rolling heads and intellectual bloodshed. Starting with the "sociobiology debates" of the late 1970s through mid-80s and continuing through the "science wars" of the early-mid 1990s allegations and recriminations of the most serious sort have been almost casually poured into the air: racism, sexism, Social Darwinism, biological determinism, disciplinary colonialism, disciplinary xenophobia, and "biophobia." 4 However, despite entrenched, sometimes zealous opposition, evolutionary thinking has firmly established itself in the social sciences. Thumbing through leading social science journals, it is no longer a shock to encounter articles exploring traditional topics with shiny new Darwinian tools. This stands in stark contrast to the situation in the decades immediately following World War II, where applying biology to human behavior and culture was virtually taboo. In fact, the UNESCO statement of 1952 explicitly tabooed human behavioral biology as scientifically and politically incorrect. Moreover, this phenomenon is in marked contrast to the mainstream social science of the late 1970s and early 1980s, which was in the midst of a wicked backlash against the resurgence of biological inquiry into behavior represented in sociobiology.Currently, while human behavioral biology retains many social scientist critics, and while certain social science fields remain largely hostile or indifferent, invoking biology to explain social behavior is moving toward the mainstream. Almost thirty years after E. O. Wilson made, in Sociobiology (1975), his first call for a merger of disciplines under a new biological synthesis, biology-savvy social scientists and social-science-savvy biologists have provided startling new insights into a host of topics traditionally examined in isolation from biology: gender differences, criteria for mate choice, resource acquisition and allocation, aggression, cooperation, xenophobia, ethnocentrism, sexual politics, religious sensibilities, social hierarchy, moral codes, etc. 5Though one must be careful not to overstate the progress, we are [End Page 256] witnessing...

The Tree of Nature represents an IT-based approach to understanding Nature in the light of present-day scientific knowledge. The universe, in this view, consists of discrete entities; these are not material particles, however, but information processing events that produce observable changes in the world. The surprising result of this analysis is that the workings of Nature are based on a decision tree consisting of two dozen parameters. The tree is similar to the evolutionary phylogenetic system of the (...) various forms of life, but it is far more fundamental; constituting, as it does, the very base of everything that exists. The overall conclusion is that the universe is steadily producing new information. Metaphorically speaking, it constitutes a self-unfolding story in which events do not pass away into non-existence but instead remain forever as an indelible part of the whole. This also holds true for integrated sets of events, such as the lifetime experiences of an individual. The Tree of Nature leads to the following testable prediction: A successful quantum-gravity theory will involve the notion of a strong complementarity between gravity and the strong nuclear force.

Common ancestry is one of the pillars of Darwin’s theory of evolution. Today, the Tree of Life, which represents how all life is genealogically related, is often thought of as an essential component in the foundations of biological systematics and so therefore of evolutionary theory – and perhaps all of biology itself. It is an iconic representation in biology and even penetrates into popular culture.

In a recent paper,(1) palaeontologist Mike Benton claimed that our ability to reconstruct accurately the tree of Life may not have improved significantly over the last 100 years. This implies that the cladistic and molecular revolutions may have promulgated as much bad “black box” science as rigorous investigation. Benton's assessment was based on the extent to which cladograms (typically constructed with reference only to distributions of character states) convey the same narrative as the geochronological ages of fossil taxa (an (...) independent data set). Fossil record quality varies greatly between major clades, and the palaeontological dating “yardstick” may be more appropriate for some groups than others.

Venerable tradition allies the Torah with Wisdom, a “tree of life.”2 The tree of life is an ancient mythic symbol of the earth mother. This essay demonstrates the capacity of the Torah to facilitate a reintegrative return to the mother when, as now, the religious narratives falter that once seemed to ensure the unity of man made in the image of God conceived only as the Father. Participating in the process of this return one discovers beneath the Torah's (...) fractured narrative surface a reduplicative pattern based on the logic of the unconscious, which is founded on the repressed prelinguistic bond with all life formed at the maternal breast. This pattern reflects the recombinant properties that the unconscious shares with the earth, which breaks down and regenerates dead matter as the unconscious breaks down and regenerates the meaning of words. Folded into rhetorical tropes as into a single letter, the Torah's regenerative pattern repeatedly recalls to man what it means to be human, unique among but also one with all the diverse life of the earth.

A common view is that species occupy a unique position on the Tree of Life. Evaluating this claim requires an understanding of what the Tree of Life represents. The Tree represents history, but there are at least three biological levels that are often said to have genealogies: species, organisms, and genes. Here I focus on defending the plausibility of a gene-based account of the Tree. This leads to an account of species that are determined by gene (...) genealogies. On this view, an exclusive group is a group of organisms that forms a clade for a higher proportion of the genome than any conflicting clade. Taxa occupy a unique position in what can be called the ‘primary concordance tree’. But each gene has its own historical ‘Tree of Life’. I conclude by arguing that both organismal pedigrees with their corresponding Tree as well as gene genealogies and their trees are objectively real and play important, but different, roles in biological practice.

Originally published in 1948, this book contains an edited version of The Tree of Commonwealth, which was written by Edmund Dudley while imprisoned in the Tower of London in 1509 prior to his execution for treason the following year. Brodie notes any variations between manuscripts and provides a brief biography of Dudley and the impact of his famous text on later monarchs. This book will be of value to anyone with an interest in Tudor history or the history of (...) English statesmanship. (shrink)

This paper discusses a krater recently discovered in a cultic building at Tel Burna in the Shephelah. Of special interest is the krater’s relatively well-preserved decoration containing multiple nature scenes related to the so-called tree of life or sacred tree motif. The krater’s physical description and archaeological context and the decoration’s relationship to relevant comparanda are explored in order to elucidate the significance of its iconography. In light of this discussion, we conclude that the decoration includes an abstract (...) representation of a Canaanite goddess as a “pubis of life” variation of the “tree of life” motif on the krater as a votive vessel in the Late Bronze Age cult.

Descartes' image of the tree of knowledge from the preface to the French edition of the Principles of Philosophy is usually taken to represent Descartes' break with the past and with the fragmentation of knowledge of the schools. But if Descartes' tree of knowledge is analyzed in its proper context, another interpretation emerges. A series of contrasts with other classifications of knowledge from the seventeenth and eighteenth centuries raises some puzzles: claims of originality and radical break from the (...) past do not seem warranted. Further contrasts with Descartes' unpublished writings and with school doctrines lead to the ironic conclusion that, in the famous passage, Descartes is attempting to appeal to conventional wisdom and trying to avoid sounding novel.
