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)

What sets the practice of rigorously tested, sound science apart from pseudoscience? In this volume, the contributors seek to answer this question, known to philosophers of science as “the demarcation problem.” This issue has a long history in philosophy, stretching as far back as the early twentieth century and the work of Karl Popper. But by the late 1980s, scholars in the field began to treat the demarcation problem as impossible to solve and futile to ponder. However, the essays that (...) Massimo Pigliucci and Maarten Boudry have assembled in this volume make a rousing case for the unequivocal importance of reflecting on the separation between pseudoscience and sound science.

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)

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)

Evolutionary biology is a field currently animated by much discussion concerning its conceptual foundations. On the one hand, we have supporters of a classical view of evolutionary theory, whose backbone is provided by population genetics and the so-called Modern Synthesis (MS). On the other hand, a number of researchers are calling for an Extended Synthe- sis (ES) that takes seriously both the limitations of the MS (such as its inability to incorporate developmental biology) and recent empirical and theoretical research on (...) issues such as evolvability, modularity, and self-organization. In this article, I engage in an in-depth commentary of an influential paper by population geneticist Michael Lynch, which I take to be the best defense of the MS-population genetics position published so far. I show why I think that Lynch’s arguments are wanting and propose a modification of evolutionary theory that retains but greatly expands on population genetics. (shrink)

In a now classic paper published in 1991, Alberch introduced the concept of genotype–phenotype (G!P) mapping to provide a framework for a more sophisticated discussion of the integration between genetics and developmental biology that was then available. The advent of evo-devo first and of the genomic era later would seem to have superseded talk of transitions in phenotypic space and the like, central to Alberch’s approach. On the contrary, this paper shows that recent empirical and theoretical advances have only sharpened (...) the need for a different conceptual treat- ment of how phenotypes are produced. Old-fashioned metaphors like genetic blueprint and genetic programme are not only woefully inadequate but positively misleading about the nature of G!P, and are being replaced by an algorithmic approach emerging from the study of a variety of actual G!P maps. These include RNA folding, protein function and the study of evolvable soft- ware. Some generalities are emerging from these disparate fields of analysis, and I suggest that the concept of ‘developmental encoding’ (as opposed to the classical one of genetic encoding) provides a promising computational–theoretical underpinning to coherently integrate ideas on evolvability, modularity and robustness and foster a fruitful framing of the G!P mapping problem.

In this paper I outline a theory of legitimacy that grounds the state’s right to rule on a natural duty not to harm others. I argue that by refusing to enter the state, anarchists expose those living next to them to the dangers of the state of nature, thereby posing an unjust threat. Since we have a duty not to pose unjust threats to others, anarchists have a duty to leave the state of nature and enter the state. This duty (...) correlates to a claim-right possessed by those living next to them, who also have a right to act in self-defence to enforce this obligation. This argument, if successful, would be particularly attractive, as it provides an account of state legitimacy without importing any normative premises that libertarians would reject. (shrink)

While the search for the neural basis of the language of thought is a laudable enterprise, and the article by Hurford a valiant first attempt, we argue that in investigating the argument structure of natural language it will ultimately prove more fruitful to consider the restrictions forced on the system by its inherently syntactic character.

According to the received view (Bocheński, Kneale), from the end of the fourteenth to the second half of nineteenth century, logic enters a period of decadence. If one looks at this period, the richness of the topics and the complexity of the discussions that characterized medieval logic seem to belong to a completely different world: a simplified theory of the syllogism is the only surviving relic of a glorious past. Even though this negative appraisal is grounded on good reasons, it (...) overlooks, however, a remarkable innovation that imposes itself at the beginning of the sixteenth century: the attempt to connect the two previously separated disciplines of logic and mathematics. This happens along two opposite directions: the one aiming to base mathematical proofs on traditional (Aristotelian) logic; the other attempting to reduce logic to a mathematical (algebraical) calculus. This second trend was reinforced by the claim, mainly propagated by Hobbes, that the activity of thinking was the same as that of performing an arithmetical calculus. Thus, in the period of what Bocheński characterizes as ‘classical logic’, one may find the seeds of a process which was completed by Boole and Frege and opened the door to the contemporary, mathematical form of logic.

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.

The paper is devoted to Richard Rorty’s thought, with the aim of exploiting a certain contention of his and directing it, as it were, against Rorty himself. Here is the contention: he thinks that – when it comes to metaphysical questions such as realism and anti-realism – the only kind of argument a pragmatist has at her disposal is rhetorical. Following the lines of the well-known wager Blaise Pascal laid on the belief in the existence of God, I will try (...) to show that the realist can avail herself of a rhetorical argument in favor of her view which is more convincing than any rhetorical argument of a Rortyan kind, while abiding by the Rortyan maxim according to which ‘What has no bearing on our practice, shouldn’t have a bearing on philosophy’. This will allow me to challenge Rorty standing on his home ground. (shrink)

Were we designed by an intelligent creation? Not likely: living organisms are designed, yes, but not intelligently...

In a life-span perspective, Baglio and Marchetti make the hypothesis of “the existence of multiple kinds of Theory of Mind” and urge the transition from a discrete to a dimensional approach in the study of mentalization (“ToM may vary along a quantitative and a qualitative continuum”). We resist such a plea and argue that we can stick to a discrete approach which posits just a single early-developing mindreading system, and then works out a “third-person first” perspective on mentalization, according to (...) which the understanding of other minds both ontogenetically precedes and grounds the understanding of our own minds. In this third-person first framework, Baglio and Marchetti’s claim that mentalization is “a multifaceted set of competences liable to influence -- and be influenced by -- a manifold of psychosocial aspects” is reformulated as follows: first-person mentalization evolves in an interplay of third-person mentalization, autobiographical memory and socio-communicative skills attuned by cultural variables. Let us examine these points one by one.In the first place, we take a nativist-modularist perspective on third-person mentalization (henceforth “mindreading”). After Onishi and Baillargeon’s (2005) groundbreaking paper, enough evidence has accumulated to endorse the hypothesis that a form of primary mindreading is not a developmental achievement, but an innate social-cognitive evolutionary adaptation (Baillargeon et al., 2013, 2014). Such adaptation is implemented... (shrink)

Are numbers and other mathematical objects "out there" in some philosophically meaningful sense?

This paper considers the nature of schizophrenic autism and urges its importance for understanding the phenomenological core of schizophrenia. Different clinical manifestations of schizophrenic autism are demonstrated, and it is asked whether these might reflect different aspects of one underlying phenomenologically intelligible phenomenon. Four phenomenological hypotheses are put forward: that autism is a function of semantic drifting, emotional drifting, ontological incompleteness, or a particular ethic rejecting common sense. By way of conclusion an integrative hypothesis is considered: that autism is intelligible (...) in terms of the experience of disembodiment. (shrink)

Intelligent Design proponents want to distinguish themselves from creationists. But the distinction appears to be without a difference.

"The last remnant of physical objectivity of space-time" is disclosed, beyond the Leibniz equivalence, in the case of a continuous family of spatially non-compact models of general relativity. The physical individuation of point-events is furnished by the intrinsic degrees of freedom of the gravitational field, (viz, the "Dirac observables") that represent - as it were - the "ontic" part of the metric field. The physical role of the "epistemic" part (viz. the "gauge" variables) is likewise clarified. At the end, a (...) peculiar four-dimensional "holistic and structuralist" view of space-time emerges which includes elements common to the tradition of both substantivalism and relationism. The observables of our models undergo real "temporal change" and thereby provide a counter-example to the thesis of the "frozen-time" picture of evolution. (shrink)

Due to the current availability of the English translation of almost all of Lesniewski's works it is now possible to give a clear and detailed picture of his ideas. Lesniewski's system of the foundation of mathematics is discussed. In abrief ouüine of his three systems Mereology, Ontology and Protothetics his positions conceming the problems of the forms of expression, proper names, synonymity, analytic and synthetic propositions, existential propositions, the concept of logic, and his views of theory of science and metaphysics (...) are sketched. The influence of Mill, Lukasiewicz, Austrian philosophy and especially Petrazycki on his thinking is evaluated and an interpretation is suggested setting him squarely in a tradition of classical Aristotelian logic.

Si esamina, nell'esperienza giuridica, lo stato di eccezione nel senso più generale, come fenomeno straordinario, eventuale, ma che, una volta verificatosi, non possa rimanere giuridicamente ignorato né inspiegabile, analogamente al concetto del miracolo in teologia. Lo stato di eccezione non può essere neppure limitato alle sole condizioni di necessità; non può essere affrontato e risolto con le sole argomentazioni inerenti lo stato di costrizione, che rappresenta solo un aspetto della sua casistica, comprendente anche fattispecie create dall'esclusivo e libero esercizio della (...) volontà di chi provoca o determina lo stesso stato di eccezione. Per analizzare le caratteristiche del ragionamento giuridico nello stato di eccezione, si esaminano due casi. Il primo caso riguarda la cospirazione, il secondo caso di eccezione è la definizione giuridica dei diritti umani. (shrink)

This paper is about the development of a face-to-face collaborative technology to support shifting attitudes of participants in conflict via a narration task. The work is based on two cultural elements: conflict resolution theory and the design of a collaboration enforcing interface designed specifically for the task. The general claim is that participants may achieve a greater understanding of and appreciation for the other’s viewpoint under conditions that support partaking in a tangible joint task and creating a shared narration. Specifically, (...) a co-located interface for producing a joint narration as a tool for favoring reconciliation is presented and discussed. The process based on this technology implicitly includes classical steps in conflict resolution approaches, such as escalation and de-escalation. Our goal is to show that this interface is effective and constitutes an alternative to a typical face-to-face moderated discussion. (shrink)

Cyber warfare has changed the scenario of war from an empirical and a theoretical viewpoint. Cyber war is no longer based on physical violence only, but on military, political, economic and ideological strategies meant to exploit a state’s informational resources. This means that a deeper understanding of what cyber war is requires us to adopt an informational approach. This approach may enable us to account for the two-dimensional nature of cyber war, to revise the notion of violence on which war (...) is premised and to understand to what extent the traditional ideas of ‘just war’ may apply to the scenario of cyber warfare. This point is crucial, since it concerns whether a cyber war is meant to restore a broken international political and legal order or to participate in its construction. (shrink)

Stoicism is an ancient Greco-Roman practical philosophy focused on the ethics of everyday living. It is a eudaemonistic (i.e., emphasizing one’s flourishing) approach to life, as well as a type of virtue ethics (i.e., concerned with the practice of virtues as central to one’s existence). This paper summarizes the basic tenets of Stoicism and discusses how it tackles the issues of death and suicide. It presents a number of exercises that modern Stoics practice in order to prepare for death (one’s (...) own, or those of relatives and friends). It argues that modern Stoicism is a viable personal philosophy. (shrink)

In questo articolo ci proponiamo di portare alla luce i netti confini che separano i concetti di mindreading, introspezione e metacognizione con l’obiettivo di dissipare alcuni fraintendimenti presenti nella letteratura clinica. A tal fine, iniziamo identificando due posizioni principali nell’odierno dibattito filosofico cognitivo sull’introspezione: da un lato le teorie che sostengono che “introspezione” è la denominazione impropria per un processo interpretativo; da un altro lato le teorie che continuano a ritenere che almeno in alcuni casi l’accesso alla propria mente sia (...) diretto e non interpretativo. Dopodiché prendiamo posizione contro le teorie dell’accesso diretto e in favore di una certa versione dell’approccio interpretativista. Infine, da questo approccio ricaviamo alcune linee guida per l’uso della Theory of Mind in neuropsichiatria cognitiva. (shrink)

Christiansen & Chater (C&C) have taken the interactionist approach to linguistic universals to an extreme, adopting the metaphor of language as an organism. This metaphor adds no insights to five decades of analyzing language universals as the result of interaction of linguistically unique and general cognitive systems. This metaphor is also based on an outmoded view of classical Darwinian evolution and has no clear basis in biology or cognition.

_Abstract_: In this paper we carve out a _reformist_ agenda within the debate on the foundations of cognitive science, incorporating some important ideas from the 4E cognition literature into the computational-representational framework. We are deeply sympathetic to this reformist program since we think that, despite strong criticism of the concept of computation and the related notion of representation, computational models should still be at the core of the study of mind. At the same time, we recognize the need for a (...) liberalization of the computational and representational framework that can address deep dissatisfaction with the anti-biologism and radical internalism of classical cognitive science. However, reform is a difficult task, so in this article we focus on two open questions within the reformist agenda. The first concerns the possibility of combining mechanistic-computational and dynamical explanations. The second concerns related changes in the notion of representation and its use (with special attention to Andy Clark’s radical predictive processing). _Keywords_: Continuum of Representational Genera;_ _Enactivism; Predictive Processing; Radical Embodied Cognition Thesis; Representationalism _ Due problemi aperti nell’agenda riformista della filosofia della scienza cognitiva _ _Riassunto_: In questo lavoro identifichiamo un’agenda _riformista_ nel dibattito sui fondamenti della scienza cognitiva che incorpora alcune idee centrali provenienti dalla letteratura sulla cognizione 4E all’interno di una cornice computazionalista e rappresentazionalista. Tale agenda considera il quadro computazionalista e rappresentazionalista ancora imprescindibile ai fini dello studio integrato della mente e del cervello, ma ne persegue una liberalizzazione nell’intento di renderlo idoneo ad accogliere alcuni importanti spunti emersi dalla letteratura sulla cognizione delle 4E. Tuttavia, riformare è un compito difficile. In questo articolo ci concentriamo su due problemi aperti nell’agenda riformista. Il primo riguarda la possibilità di mettere assieme le spiegazioni meccaniciste e computazionaliste con quelle dinamiche. Il secondo riguarda i cambiamenti relativi alla nozione di rappresentazione e al suo impiego (con particolare attenzione all’elaborazione predittiva radicale di Andy Clark). _Parole chiave_: Continuum dei generi rappresentazionali;_ _Elaborazione predittiva; Enattivismo; Tesi della cognizione incarnata radicale; Rappresentazionalismo.

This article focuses on ancient and contemporary accounts of selfhood and on their ontological background. Among ancient theories, the main focus are Plato’s and Plotinus’ accounts of soul and selfhood. Their ontological framework now appears outdated but, somewhat paradoxically, it also explains why Plato’s and Plotinus’ analyses are closer to a naturalised metaphysics of the self than those of the Cartesian tradition. Accordingly, human beings are not simple subjects essentially characterised by consciousness; consciousness and mental life are not co-extensive; our (...) selfhood entails a striving towards the unity of various layers. These insights come up again in recent debates, but they are now re-shaped within a framework in which philosophy of mind and behavioural sciences are combined in an effort to develop a notion of the self which is realist, yet does not entail any metaphysically grounded dualism.

The Hamiltonian structure of General Relativity (GR), for both metric and tetrad gravity in a definite continuous family of space-times, is fully exploited in order to show that: i) the "Hole Argument" can be bypassed by means of a specific "physical individuation" of point-events of the space-time manifold M^4 in terms of the "autonomous degrees of freedom" of the vacuum gravitational field (Dirac observables), while the "Leibniz equivalence" is reduced to differences in the "non-inertial appearances" (connected to gauge variables) of (...) the same phenomena. ii) the chrono-geometric structure of a solution of Einstein equations for given, gauge-fixed, initial data (a "3-geometry" satisfying the relevant constraints on the Cauchy surface), can be interpreted as an "unfolding" in mathematical global time of a sequence of "achronal 3-spaces" characterized by "dynamically determined conventions" about distant simultaneity. This result stands out as an important conceptual difference with respect to the standard chrono-geometrical view of Special Relativity (SR) and allows, in a specific sense, for an "endurantist" interpretations of ordinary physical objects in GR.

How should we live? According to philosopher and biologist Massimo Pigliucci, the greatest guidance to this essential question lies in combining the wisdom of 24 centuries of philosophy with the latest research from 21st century science. In Answers for Aristotle, Pigliucci argues that the combination of science and philosophy first pioneered by Aristotle offers us the best possible tool for understanding the world and ourselves. As Aristotle knew, each mode of thought has the power to clarify the other: science (...) provides facts, and philosophy helps us reflect on the values with which to assess them. But over the centuries, the two have become uncoupled, leaving us with questions—about morality, love, friendship, justice, and politics—that neither field could fully answer on its own. Pigliucci argues that only by rejoining each other can modern science and philosophy reach their full potential, while we harness them to help us reach ours. Pigliucci discusses such essential issues as how to tell right from wrong, the nature of love and friendship, and whether we can really ever know ourselves—all in service of helping us find our path to the best possible life. Combining the two most powerful intellectual traditions in history, Answers for Aristotle is a remarkable guide to discovering what really matters and why. (shrink)
