Contemporary theories of consciousness are based on widely different concepts of its nature, most or all of which probably embody aspects of the truth about it. Starting with a concept of consciousness indicated by the phrase “the feeling of what happens” (the title of a book by Antonio Damásio), we attempt to build a framework capable of supporting and resolving divergent views. We picture consciousness in terms of Reality experiencing itself from the perspective of cognitive agents. Each conscious experience is (...) regarded as composed of momentary feeling events that are combined by recognition and evaluation into extended conscious episodes that bind cognitive contents with a wide range of apparent durations (0.1 secs to 2 or more secs, for us humans, depending on circumstances and context). Three necessary conditions for the existence of consciousness are identified: a) a ground of Reality, envisaged as an universal field of potentiality encompassing all possible manifestations, whether material or 'mental'; b) a transitional zone, leading to; c) a manifest world with its fundamental divisions into material, 'informational' and quale-endowed aspects. We explore ideas about the nature of these necessary conditions, how they may relate to one another and whether our suggestions have empirical implications. (shrink)

What happens to the inner light of consciousness with the death of the individual body and brain? Reductive materialism assumes it simply fades to black. Others think of consciousness as indicating a continuation of self, a transformation, an awakening or even alternatives based on the quality of life experience. In this issue, speculation drawn from theoretic research are presented. -/- Table of Contents Epigraph: From “The Immortal”, Jorge Luis Borges iii Editor’s Introduction: I Killed a Squirrel the Other Day, Gregory (...)

Just war theory is currently dominated by two positions. According to the orthodox view, provided that jus in bello principles are respected, combatants have an equal right to fight, regardless of the justice of the cause pursued by their state. According to “revisionists” whenever combatants lack reasons to believe that the war they are ordered to fight is just, their duty is to disobey. I argue that when members of a legitimate state acting in good faith are ordered to fight, (...) they acquire a pro-tanto obligation to obey which does not depend for its validity on the justice of the cause being pursued. However, when the war is unjust, this obligation may be overridden, under certain conditions, by the obligation not to contribute to the unjustified killing of innocents. This is because the pro-tanto force of the duty to obey the law is best understood in terms of “presumptive”, rather than “exclusionary” reasons for action. This approach captures the insights of both the orthodox and the revisionist view, while avoiding the problems that afflict each of them. (shrink)

Genes are often described by biologists using metaphors derived from computa- tional science: they are thought of as carriers of information, as being the equivalent of ‘‘blueprints’’ for the construction of organisms. Likewise, cells are often characterized as ‘‘factories’’ and organisms themselves become analogous to machines. Accordingly, when the human genome project was initially announced, the promise was that we would soon know how a human being is made, just as we know how to make airplanes and buildings. Impor- tantly, (...) modern proponents of Intelligent Design, the latest version of creationism, have exploited biologists’ use of the language of information and blueprints to make their spurious case, based on pseudoscientific concepts such as ‘‘irreducible complexity’’ and on flawed analogies between living cells and mechanical factories. However, the living organ- ism = machine analogy was criticized already by David Hume in his Dialogues Concerning Natural Religion. In line with Hume’s criticism, over the past several years a more nuanced and accurate understanding of what genes are and how they operate has emerged, ironically in part from the work of computational scientists who take biology, and in particular developmental biology, more seriously than some biologists seem to do. In this article we connect Hume’s original criticism of the living organism = machine analogy with the modern ID movement, and illustrate how the use of misleading and outdated metaphors in science can play into the hands of pseudoscientists. Thus, we argue that dropping the blueprint and similar metaphors will improve both the science of biology and its understanding by the general public. (shrink)

Science has always strived for objectivity, for a ‘‘view from nowhere’’ that is not marred by ideology or personal preferences. That is a lofty ideal toward which perhaps it makes sense to strive, but it is hardly the reality. This collection of thirteen essays assembled by Denis R. Alexander and Ronald L. Numbers ought to give much pause to scientists and the public at large, though historians, sociologists and philosophers of science will hardly be surprised by the material covered here.

In lieu of an abstract, here is a brief excerpt of the content:Why Gaia?Massimo Pigliucci (bio)The Gaia Hypothesis: Science on a Pagan Planet, Michael Ruse, Chicago: University of Chicago Press, 2013. 272 pages.“The Gaia Hypothesis: Science on a Pagan Planet tells a story that comes out of the 1960s, a story that reflects all of the beliefs and enthusiasms and tensions of that decade.” So begins Michael Ruse’s fascinating, if at times puzzling, exploration of James Lovelock’s famous idea that (...) our planet is, in a serious scientific sense, a living organism with a tendency of taking care of (her)self. But why tell this particular story, especially considering that Gaia hardly makes an appearance in today’s scientific or philosophical publications, and doesn’t even seem quite that popular with the lay public as it used to be? Because, as Ruse tells us near the end of the book, at the onset of chapter seven: “the paradox that set us on our path [is] why the scientific community reacted so negatively to the Gaia hypothesis, whereas the public reaction was so positive.”As it turns out, there is a good answer to that conundrum, one that Ruse himself lays out clearly in the last chapter of the book, and which makes the reader wonder why this should count a paradox at all. But we will get there in due time. First, the basics: the so-called Gaia hypothesis is the brainchild of iconoclastic inventor-turned-independent-scientist James Lovelock, who later got significant help in elaborating (and promoting) his ideas from another iconoclast, biologist Lynn Margulis. By the time you get to the end of Ruse’s engaging book, however, you won’t have gained a particularly good understanding of what the hypothesis actually consists. But that’s not Ruse’s fault, it is Lovelock’s (and Margulis’). At times it sounds like the entirely uncontroversial claim that the Earth’s [End Page 117] biosphere is a somewhat homeostatic system—i.e., a biophysical system that is resistant to major changes, at the least within a certain range (the planet’s atmosphere, after all, did change dramatically early on, increasing its oxygen content as a result of the evolution of photosynthetic organisms—the anaerobic life forms that had up to that point been dominant did not appreciate the novelty). At other times the claim is downright preposterous: the Earth literally is a living organism (according to Lovelock) (Chapter 7),1 a finding that allegedly puts in question the whole Darwinian view of biological evolution (according to Margulis) (Chapter 7), a position that can only be characterized as nonsense on stilts. At yet other moments, Gaia is presented as just a metaphor to help us wrap our minds around the complexities (and homeostatic properties) of the world’s ecosystems (Chapter 8). It is this never-ending oscillation between the trivial and the bizarre that has led the majority of scientists to write off Gaia, to the chagrin of Lovelock, Margulis, and a large number of New Age tree huggers from the 1960s.Indeed, the scientific reaction to Gaia was swift and ranging from the condescending to the unforgiving. Evolutionary biologist John Maynard Smith—never one to mince words—called it “an evil religion” (Chapter 2). Another evolutionary biologist, Stephen Jay Gould (whose own disagreements with Maynard Smith became legendary) said that “Gaia strikes me as a metaphor, not a mechanism” (Chapter 2). Ecologist Robert May, who eventually became president of the Royal Society, called Lovelock “a holy fool” (Chapter 2). The highly respected theoretical biologist W.D. Hamilton said that in order for the hypothesis to work, it would require “treaties between Neptune and Zeus, a Gaian Interpol, conventions about bills of lading for chemical transport by air and water, and so on” (Chapter 7). Finally, Richard Dawkins accused Lovelock of committing the fallacy of “the BBC theorem,” assuming (or wishfully thinking) that the world is a harmonious place, just like in naive BBC nature documentaries (Chapter 2).You get the gist: pretty much from the beginning, and with very few exceptions, the scientific establishment rejected Gaia on the grounds that it is not a scientific hypothesis at all, and that its main tenets actually go against pretty...

The paper investigates the role played by pre-scientific experience in the philosophy of Josiah Royce and Edmund Husserl. Such a notion, generally associated with Husserl’s conception of the life-world (Lebenswelt) in the Crisis of European Sciences and Transcendental Phenomenology (1936), finds an equivalent and historical antecedent in Royce’s distinction between a world of description and a world of appreciation. The final goal is to show how, despite their different philosophical frameworks, Royce and Husserl agree on the idea that, through the (...) rejection of the world given through mere perception (Lebenswelt/world of appreciation), European sciences have somehow failed their task of universality. As it will be shown, this idea is also due to methodological affinities among the two thinkers. The experience of interconnectedness among individual minds, while precluded in the mere scientific explanation of the world, it becomes possible through the enactment of the Lebenswelt or, as in Royce’s case, through a return to the experience of the world of appreciation.

It is an unfortunate fact of academic life that there is a sharp divide between science and philosophy, with scientists often being openly dismissive of philosophy, and philosophers being equally contemptuous of the naivete ́ of scientists when it comes to the philosophical underpinnings of their own discipline. In this paper I explore the possibility of reducing the distance between the two sides by introducing science students to some interesting philosophical aspects of research in evolutionary biology, using biological theories of (...) the origin of religion as an example. I show that philosophy is both a discipline in its own right as well as one that has interesting implications for the understanding and practice of science. While the goal is certainly not to turn science students into philoso- phers, the idea is that both disciplines cannot but benefit from a mutual dialogue that starts as soon as possible, in the classroom.

Recent debates between proponents of the modern evolutionary synthesis (the standard model in evolutionary biology) and those of a possible extended synthesis are a good example of the fascinating tangle among empirical, theoretical, and conceptual or philosophical matters that is the practice of evolutionary biology. In this essay, we briefly discuss two case studies from this debate, highlighting the relevance of philosophical thinking to evolutionary biologists in the hope of spurring further constructive cross-pollination between the two fields.

Law is traditionally related to the practice of command and hierarchy. It seems that a legal rule should immediately establish a relation between a superior and an inferior. This hierarchical and authoritharian view might however be challenged once the phenomenology of the rule is considered from the internal point of view, that is, from the stance of those that can be said to “use” rather than to “suffer” the rules themselves. A practice oriented approach could in this way open up (...) a more liberal, and also somehow less parochial and ideological, road for legal theory. This is – it is argued in the paper – the programme, or better, the promise we can find in Herbert Hart’s main work, The Concept of Law. The article tries to render this promise more transparent while, nonetheless, not eschewing the blind sides of its narrative and argumentative strategy. (shrink)

In the 17th century the dissemination of philosophical ideas relied also on the critical summaries and reviews published by the journals. The focus of this paper is the reactions of two of these journals – the Journal de Trévoux, edited by the Jesuits of the Parisian Collège Louis Le Grand, and the Journal des Sçavans – to Condillac’s works. The Jesuit journal, under the direction of pére Berthier – probably himself the author of the reviews – had a precise plan (...) in presenting Condillac’s philosophy as an anti-empiricist and anti-materialist doctrine, sometime giving a misrepresentation of the author’s thought, which is also criticized on some points. The decision of the Journal de Trévoux to review the main works of Condillac is anyway worthy of attention, and probably betrays a certain interest toward the more up to date philosophical enquiry. The Journal des Sçavans was on the other hand more faithful in presenting Condillac’s works. (shrink)

Il lavoro di tesi analizza il problema cristologico nella filosofia di Spinoza alla luce delle riletture contemporanee sul tema, attraversando questioni di argomento etico, pedagogico e religioso. Viene condotto dall'autore un meticoloso lavoro di analisi relativo alle occorrenze testuali delle espressioni riferite a Cristo e ai Cristiani nell'intera produzione spinoziana. Sebbene il tema cristologico non sia affrontato quasi mai in modo esplicito dal filosofo olandese, il lavoro di tesi mostra quanto diffusi siano tali riferimenti e come possa essere interessante rileggere (...) Spinoza proprio a partire dalla sua profonda ammirazione nei confronti della figura più affascinante della storia dell'Occidente. (shrink)

Research in ecology and evolutionary biology (evo-eco) often tries to emulate the “hard” sciences such as physics and chemistry, but to many of its practitioners feels more like the “soft” sciences of psychology and sociology. I argue that this schizophrenic attitude is the result of lack of appreciation of the full consequences of the peculiarity of the evo-eco sciences as lying in between a-historical disciplines such as physics and completely historical ones as like paleontology. Furthermore, evo-eco researchers have gotten stuck (...) on mathematically appealing but philosophi- cally simplistic concepts such as null hypotheses and p-values defined according to the frequentist approach in statistics, with the consequence of having been unable to fully embrace the complexity and subtlety of the problems with which ecologists and evolutionary biologists deal with. I review and discuss some literature in ecology, philosophy of science and psychology to show that a more critical methodological attitude can be liberating for the evo-eco scientist and can lead to a more fecund and enjoyable practice of ecology and evolutionary biology. With this aim, I briefly cover concepts such as the method of multiple hypotheses, Bayesian analysis, and strong inference. (shrink)

The Modern Synthesis (MS) is the current paradigm in evolutionary biology. It was actually built by expanding on the conceptual foundations laid out by its predecessors, Darwinism and neo-Darwinism. For sometime now there has been talk of a new Extended Evolutionary Synthesis (EES), and this article begins to outline why we may need such an extension, and how it may come about. As philosopher Karl Popper has noticed, the current evolutionary theory is a theory of genes, and we still lack (...) a theory of forms. The field began, in fact, as a theory of forms in Darwin’s days, and the major goal that an EES will aim for is a unification of our theories of genes and of forms. This may be achieved through an organic grafting of novel concepts onto the foundational structure of the MS, particularly evolvability, phenotypic plasticity, epigenetic inheritance, complexity theory, and the theory of evolution in highly dimensional adaptive landscapes.

Evolutionary theory is undergoing an intense period of discussion and reevaluation. This, contrary to the misleading claims of creationists and other pseudoscientists, is no harbinger of a crisis but rather the opposite: the field is expanding dramatically in terms of both empirical discoveries and new ideas. In this essay I briefly trace the conceptual history of evolutionary theory from Darwinism to neo-Darwinism, and from the Modern Synthesis to what I refer to as the Extended Synthesis, a more inclusive conceptual framework (...) containing among others evo–devo, an expanded theory of heredity, elements of complexity theory, ideas about evolvability, and a reevaluation of levels of selection. I argue that evolutionary biology has never seen a paradigm shift, in the philosophical sense of the term, except when it moved from natural theology to empirical science in the middle of the 19th century. The Extended Synthesis, accordingly, is an expansion of the Modern Synthesis of the 1930s and 1940s, and one that—like its predecessor—will probably take decades to complete. (shrink)

The idea of genetic assimilation, that environmentally induced phenotypes may become genetically fixed and no longer require the original environmental stimulus, has had varied success through time in evolutionary biology research. Proposed by Waddington in the 1940s, it became an area of active empirical research mostly thanks to the efforts of its inventor and his collaborators. It was then attacked as of minor importance during the ‘‘hardening’’ of the neo-Darwinian synthesis and was relegated to a secondary role for decades. Recently, (...) several papers have appeared, mostly independently of each other, to explore the likelihood of genetic assimilation as a biological phenomenon and its potential importance to our understanding of evolution. In this article we briefly trace the history of the concept and then discuss theoretical models that have newly employed genetic assimilation in a variety of contexts. We propose a typical scenario of evolution of genetic assimilation via an intermediate stage of phenotypic plasticity and present potential examples of the same. We also discuss a conceptual map of current and future lines of research aimed at exploring the actual relevance of genetic assimilation for evolutionary biology. (shrink)

What makes humans different from other animals, what humans are entitled to do to other species, whether time travel is possible, what limits should be placed on science and technology, the morality and practicality of genetic engineering—these are just some of the philosophical problems raised by Planet of the Apes. Planet of the Apes and Philosophy looks at all the deeper issues involved in the Planet of the Apes stories. It covers the entire franchise, from Pierre Boulle’s 1963 novel Monkey (...) Planet to the successful 2012 reboot Rise of the Planet of the Apes. The chapters reflect diverse points of view, philosophical, religious, and scientific. The ethical relations of humans with animals are explored in several chapters, with entertaining and incisive observations on animal intelligence, animal rights, and human-animal interaction. Genetic engineering is changing humans, animals, and plants, raising new questions about the morality of such interventions. The scientific recognition that humans and chimps share 99 percent of their genes makes a future in which non-human animals acquire greater importance a distinct possibility. Planet of the Apes is the most resonant of all scientific apocalypse myths. (shrink)

A quick look at the concept of reflective equilibrium in philosophy.

The aim of this paper is to provide an overview of Heidegger's philosophy and reveal a possibility of an other beginning, of which we can have only a premonition for now. The paper is very much a preparation for work which is currently underway.

When I was fifteen, I was having serious doubts about the existence of a supernatural entity benevolently looking over me, and—perhaps even more disturbingly—about the possibility of an afterlife in which I would again see my friends and relatives and exist happily ever after. It was at that point that I started reading the writings of Bertrand Russell,1,2 one of the most controversial philosophers and political activists of the Twentieth century.

During the last two decades the role of quantitative genetics in evolutionary theory has expanded considerably. Quantitative genetic-based models addressing long term phenotypic evolution, evolution in multiple environments (phenotypic plasticity) and evolution of ontogenies (developmental trajectories) have been proposed. Yet, the mathematical foundations of quantitative genetics were laid with a very different set of problems in mind (mostly the prediction of short term responses to artificial selection), and at a time in which any details of the genetic machinery were virtually (...) unknown. In this paper we discuss what a model is in population biology, and what kind of model we need in order to address the complexities of phenotypic evolution. We review the assumptions of quantitative genetics and its most recent accomplishments, together with the limitations that such assumptions impose on the modelling of some aspects of phenotypic evolution. We also discuss three alternative appr oaches to the theoretical description of evolutionary trajectories (nonlinear dynamics, complexity theory and optimization theory), and their respective advantages and limitations. We conclude by calling for a new theoretical synthesis, including quantitative genetics and not necessarily limited to the other approaches here discussed. (shrink)

Will the scientific quest ever end? Will it be with a bang or with a whisper?

A brief inquiry into philosophy of mind, its history, and its current schools of thought.

On the status of hypotheses in science, and why scientists would be better off asking questions.

The “demarcation problem,” the issue of how to separate science from pseu- doscience, has been around since fall 1919—at least according to Karl Pop- per’s (1957) recollection of when he first started thinking about it. In Popper’s mind, the demarcation problem was intimately linked with one of the most vexing issues in philosophy of science, David Hume’s problem of induction (Vickers 2010) and, in particular, Hume’s contention that induction cannot be logically justified by appealing to the fact that “it works,” (...) as that in itself is an inductive argument, thereby potentially plunging the philosopher straight into the abyss of a viciously circular argument.

In recent years, biologists have increasingly been asking whether the ability to evolve — the evolvability — of biological systems, itself evolves, and whether this phenomenon is the result of natural selection or a by-product of other evolutionary processes. The concept of evolvability, and the increasing theoretical and empirical literature that refers to it, may constitute one of several pillars on which an extended evolutionary synthesis will take shape during the next few years, although much work remains to be done (...) on how evolvability comes about.

Biological research on race has often been seen as motivated by or lending credence to underlying racist attitudes; in part for this reason, recently philosophers and biologists have gone through great pains to essentially deny the existence of biological human races. We argue that human races, in the biological sense of local populations adapted to particular environments, do in fact exist; such races are best understood through the common ecological concept of ecotypes. However, human ecotypic races do not in general (...) correspond with 'folk' racial categories, largely because many similar ecotypes have multiple independent origins. Consequently, while human natural races exist, they have little or nothing in common with 'folk' races. (shrink)

This paper focuses on the concept of symbol and tries to outline its function as a means of communication. In order to describe the communicative qualities of symbol, it is necessary to show its ethical nature. The paper analyses the role symbols play in intersubjective relations, in the construction of the individual’s reality, and in the human ability to attribute meanings and assign functions.The conceptual frame- work for the understanding of what symbol is, how it works, and how it is (...) made is a particular combination of phenomenology and pragmatism, which lies on the theory of ‘appresentation’, as we can find it in Alfred Schütz’s viewpoint. The paper invites a reflection on the power of symbol, particularly on its power to communicate the incommunicable. (shrink)

A New Italian translation of Principia Ethica coming almost 60 years after the 1964 translation by Gianni Vattimo with Nicola Abbagnano’s preface. The new edition makes room for the English text alongside the Italian translation; it includes the 1922 Preface, a bibliography of Moore’s ethical writings with critical literature, a chronology of Moore’s life and works, and an Index. The Introduction by Sergio Cremaschi reconstructs the background of ideas, concerns and intentions from which Moore’s Principia Ethica originated. It stresses the (...) role of religious concerns, as well as that of the Idealist legacy. I argue that PE is more a patchwork of incompatible lines of argument than a consistent work. It compares PE with Rashdall’s almost contemporary ethical work, suggesting that the latter defends the same general claims in a different and more plausible way, which manages to answer decisive objections. It ends with the suggestion that the emergence of Analytic Ethics was a more multi-faceted phenomenon than the received view would make us believe and the analytic tradition's wheat, that is, what logic can do for philosophy, has to be separated from the chaff, that is, the confused, and besides mutually incompatible, legacies of Utilitarianism and Idealism.

The concept of burden of proof is used in a wide range of discourses, from philosophy to law, science, skepticism, and even in everyday reasoning. This paper provides an analysis of the proper deployment of burden of proof, focusing in particular on skeptical discussions of pseudoscience and the paranormal, where burden of proof assignments are most poignant and relatively clear-cut. We argue that burden of proof is often misapplied or used as a mere rhetorical gambit, with little appreciation of the (...) underlying principles. The paper elaborates on an important distinction between evidential and prudential varieties of burdens of proof, which is cashed out in terms of Bayesian probabilities and error management theory. Finally, we explore the relationship between burden of proof and several (alleged) informal logical fallacies. This allows us to get a firmer grip on the concept and its applications in different domains, and also to clear up some confusions with regard to when exactly some fallacies (ad hominem, ad ignorantiam, and petitio principii) may or may not occur.

A discussion of plasticity genes and the genetic architecture of gene-environment interactions.

Discussions about the biological bases (or lack thereof) of the concept of race in the human species seem to be never ending. One of the latest rounds is represented by a paper by Neven Sesardic, which attempts to build a strong scientific case for the existence of human races, based on genetic, morphometric and behavioral characteristics, as well as on a thorough critique of opposing positions. In this paper I show that Sesardic’s critique falls far short of the goal, and (...) that his positive case is exceedingly thin. I do this through a combination of analysis of the actual scientific findings invoked by Sesardic and of some philo- sophical unpacking of his conceptual analysis, drawing on a dual professional background as an evolu- tionary biologist and a philosopher of science.

Mayr’s proximate–ultimate distinction has received renewed interest in recent years. Here we discuss its role in arguments about the relevance of developmental to evolutionary biology. We show that two recent critiques of the proximate–ultimate distinction fail to explain why developmental processes in particular should be of interest to evolutionary biologists. We trace these failures to a common problem: both critiques take the proximate–ultimate distinction to neglect specific causal interactions in nature. We argue that this is implausible, and that the distinction (...) should instead be understood in the context of explanatory abstractions in complete causal models of evolutionary change. Once the debate is reframed in this way, the proximate–ultimate distinction’s role in arguments against the theoretical significance of evo-devo is seen to rely on a generally implicit premise: that the variation produced by development is abundant, small and undirected. We show that a “lean version” of the proximate–ultimate distinction can be maintained even when this isotropy assumption does not hold. Finally, we connect these considerations to biological practice. We show that the investigation of developmental constraints in evolutionary transitions has long relied on a methodology which foregrounds the explanatory role of developmental processes. It is, however, entirely compatible with the lean version of the proximate–ultimate distinction. (shrink)

In this commentary, we discuss the nature of reversible and irreversible questions, that is, questions that may enable one to identify the nature of the source of their answers. We then introduce GPT-3, a third-generation, autoregressive language model that uses deep learning to produce human-like texts, and use the previous distinction to analyse it. We expand the analysis to present three tests based on mathematical, semantic, and ethical questions and show that GPT-3 is not designed to pass any of them. (...) This is a reminder that GPT-3 does not do what it is not supposed to do, and that any interpretation of GPT-3 as the beginning of the emergence of a general form of artificial intelligence is merely uninformed science fiction. We conclude by outlining some of the significant consequences of the industrialisation of automatic and cheap production of good, semantic artefacts. (shrink)

The so-called “New Atheism” is a relatively well-defined, very recent, still unfold- ing cultural phenomenon with import for public understanding of both science and philosophy. Arguably, the opening salvo of the New Atheists was The End of Faith by Sam Harris, published in 2004, followed in rapid succession by a number of other titles penned by Harris himself, Richard Dawkins, Daniel Dennett, Victor Stenger, and Christopher Hitchens.

Ever since Darwin a great deal of the conceptual history of biology may be read as a struggle between two philosophical positions: reductionism and holism. On the one hand, we have the reductionist claim that evolution has to be understood in terms of changes at the fundamental causal level of the gene. As Richard Dawkins famously put it, organisms are just ‘lumbering robots’ in the service of their genetic masters. On the other hand, there is a long holistic tradition that (...) focuses on the complexity of developmental systems, on the non-linearity of gene– environment interactions, and on multi-level selective processes to argue that the full story of biology is a bit more complicated than that. Reductionism can marshal on its behalf the spectacular successes of genetics and molecular biology throughout the 20th and 21st centuries. Holism has built on the development of entirely new disciplines and conceptual frameworks over the past few decades, including evo-devo and phenotypic plasticity. Yet, a number of biologists are still actively looking for a way out of the reductionism–holism counterposition, often mentioning the word ‘emergence’ as a way to deal with the conundrum. This paper briefly examines the philosophical history of the concept of emergence, distinguishes between epistemic and ontological accounts of it, and comments on conceptions of emergence that can actually be useful for practising evolutionary biologists.

The so-called ‘‘species problem’’ has plagued evolution- ary biology since before Darwin’s publication of the aptly titled Origin of Species. Many biologists think the problem is just a matter of semantics; others complain that it will not be solved until we have more empirical data. Yet, we don’t seem to be able to escape discussing it and teaching seminars about it. In this paper, I briefly examine the main themes of the biological and philosophical liter- atures on the species problem, (...) focusing on identifying common threads as well as relevant differences. I then argue two fundamental points. First, the species problem is not primarily an empirical one, but it is rather fraught with philosophical questions that require—but cannot be settled by—empirical evidence. Second, the (dis-)solution lies in explicitly adopting Wittgenstein’s idea of ‘‘family resemblance’’ or cluster concepts, and to consider spe- cies as an example of such concepts. This solution has several attractive features, including bringing together apparently diverging themes of discussion among bio- logists and philosophers. The current proposal is con- ceptually independent (though not incompatible) with the pluralist approach to the species problem advocated by Mishler, Donoghue, Kitcher and Dupre ́, which implies that distinct aspects of the species question need to be emphasized depending on the goals of the researcher. From the biological literature, the concept of species that most closely matches the philosophical discussion pre- sented here is Templeton’s cohesion idea. (shrink)

Science and philosophy have a very long history, dating back at least to the 16th and 17th centuries, when the first scientist-philosophers, such as Bacon, Galilei, and Newton, were beginning the process of turning natural philosophy into science. Contemporary relationships between the two fields are still to some extent marked by the distrust that maintains the divide between the so-called “two cultures.” An increasing number of philosophers, however, are making conceptual contributions to sciences ranging from quantum mechanics to evolutionary biology, (...) and a few scientists are conducting research relevant to classically philosophical fields of inquiry, such as consciousness and moral decision-making. This article will introduce readers to the borderlands between science and philosophy, beginning with a brief description of what philosophy of science is about, and including a discussion of how the two disciplines can fruitfully interact not only at the level of scholarship, but also when it comes to controversies surrounding public understanding of science.

Cabanis’ enucleation of the notion of instinct in his Rapports du physique et du moral de l’homme articulates through a critique of the use of this notion by Étienne Bonnot de Condillac, who would not have recognised the founding role of physiology in human perceptive and intellectual activity. An analysis of Cabanis’ criticism to Condillac and an investigation of the meaning attributed to the notion of instinct by both philosophers allow to individuate in this notion the expression of two different (...) types of materialism. The different position of Cabanis and Condillac on this notion, in fact, reflects the divergence on a series of notions – e.g. reflexion, sensitivity, habitus – which can be traced back to the different aims of their investigations. In addition to highlighting this basic divergence, this paper aims to bring out – especially referring to Condillac’s Logique – some points of contact, of which Cabanis seems not to have considered, concerning the conception of the human body as ‘organisation physique’.

What is the purpose of philosophy of science? Here are some answers.

Twenty years have passed since Gould and Lewontin published their critique of ‘the adaptationist program’ – the tendency of some evolutionary biologists to assume, rather than demonstrate, the operation of natural selection. After the ‘Spandrels paper’, evolutionists were more careful about producing just-so stories based on selection, and paid more attention to a panoply of other processes. Then came reactions against the excesses of the anti-adaptationist movement, which ranged from a complete dismissal of Gould and Lewontin’s contribution to a positive (...) call to overcome the problems. We now have an excellent opportunity for finally affirming a more balanced and pluralistic approach to the study of evolutionary biology. (shrink)

The term ‘naturalism’ has a long and complex history in modern philosophy. W.V.O. Quine famously advocated what has come to be known as a ‘naturalistic turn’ for philosophy as a discipline, meaning that philosophical thought should become continuous with the natural sciences – even claiming that epistemology (theory of knowledge) is nothing but applied psychology.

In addition to considerable debate in the recent evolutionary literature about the limits of the Modern Synthesis of the 1930s and 1940s, there has also been theoretical and empirical interest in a variety of new and not so new concepts such as phenotypic plasticity, genetic assimilation and phenotypic accommodation. Here we consider examples of the arguments and counter- arguments that have shaped this discussion. We suggest that much of the controversy hinges on several misunderstandings, including unwarranted fears of a general (...) attempt at overthrowing the Modern Synthesis paradigm, and some fundamental conceptual confusion about the proper roles of phenotypic plasticity and natural selection within evolutionary theory.

Few metaphors in biology are more enduring than the idea of Adaptive Landscapes, originally proposed by Sewall Wright (1932) as a way to visually present to an audience of typically non- mathematically savvy biologists his ideas about the relative role of natural selection and genetic drift in the course of evolution. The metaphor, how- ever, was born troubled, not the least reason for which is the fact that Wright presented different diagrams in his original paper that simply can- not refer (...) to the same concept and are therefore hard to reconcile with each other (Pigliucci 2008). For instance, in some usages, the landscape’s non- fitness axes represent combinations of individual genotypes (which cannot sensibly be aligned on a linear axis, and accordingly were drawn by Wright as polyhedrons of increasing dimensionality). In other usages, however, the points on the diagram represent allele or genotypic frequencies, and so are actually populations, not individuals (and these can indeed be coherently represented along continuous axes).

Natural selection [Darwin 1859] is perhaps the most important component of evolutionary theory, since it is the only known process that can bring about the adaptation of living organisms to their environments [Gould 2002]. And yet, its study is conceptually and methodologically complex, and much attention needs to be paid to a variety of phenomena that can limit the efficacy of selection [Antonovics 1976; Pigliucci and Kaplan 2000]. In this essay, I will use examples of recent work carried out in (...) my laboratory to illustrate basic research on natural selection as conducted using a variety of approaches, including field work, laboratory experiments, and molecular genetics. I also discuss the application of this array of tools to questions pertinent to conservation biology, and in particular to the all-important problem of what makes invasive species so good at creating the sort of problems they are infamous for [Lee 2002].
