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)

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)

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)

Sidgwick considered Kant as one of his masters. However, he never devoted any systematic attention to Kant’s ethical theory; moreover, in The Methods of Ethics he concluded that Kantian ethics is inadequate to guide moral life. I review Sidgwick’s references to Kant in order to show that – along with basic differences − there are significant similarities in the main project of the two philosophers; and I suggest that, should Sidgwick have deepened his understanding of Kant, he might have realised (...) that Kantian ethics offered a somewhat different way to accomplish the philosophical project he was interested in, that is, the systematisation of the morality of common sense through the establishment of certain moral axioms. I also suggest that Sidgwick’s misunderstanding of the “formula of humanity” is at the heart of his final dismissal of Kant’s ethics and that deepening his understanding of Kant might have led Sidgwick to revise his views on the rationality of egoism, thereby opening the possibility to solve the dualism of practical reason. Finally, I offer some speculations on the reasons why Sidgwick never attempted a thorough confrontation with Kant, suggesting that both his distaste for Kant’s metaphysics and his Millian utilitarian bias deterred him from it.

"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)

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.

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.

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

The article briefly analyzes the concept of a person, arguing that personhood does not coincide with the actual enjoyment of certain intellectual capacities, but is coextensive with the embodiment of a human individual. Since in PVS patients we can observe a human individual functioning as a whole, we must conclude that these patients are still human persons, even if in a condition of extreme impairment. It is then argued that some forms of minimal treatment may not be futile for these (...) patients; they may constitute a form of respect for their human dignity and benefit these patients, even if they are not aware of that. Moreover, it is important to consider the symbolic significance of care: while many believe that PVS is a kind of imprisonment, for others providing food and fluids is the only way to testify our proximity to these persons. The best policy would be to provide, as a general rule, artificial nutrition and hydration to PVS patients: this treatment could be withdrawn, after a period of observation and reflection by the family and proxies, on the basis of the proxies' objection to the continuation or of the patient's advance directives specifically referring to this situation.

Thomas Uebel’s penetrating book represents the latest outcome of a series of investigations on Otto Neurath and the “forgotten” Vienna Circle he has published over the last ten years. Within the recent galaxy of studies devoted to logical empiricism, the re-evaluation of Neurath’s all too neglected work as well as of the “first” Vienna Circle are unquestionably very much indebted to Uebel’s contributions, which may be considered, in turn, an original development of Rudolf Haller’s pioneering studies on Austrian philosophy and (...) on its leading role in the rise of the Vienna Circle. In particular, the attention paid by Haller to Neurath’s surprising epistemological actuality and moreover the “new light” he shed on the “first” Vienna Circle 1 constitute the core of Uebel’s wide program of historical and, at the same time, philosophical research. An ambitious, but successful programm, that nowadays appears to us as essentially accomplished. (shrink)

Ever since the publication of Richard Dawkins' The Selfish Gene, a book for the lay reader that popularized the ideas of influential evolutionary biologists like William Hamilton and George Williams, there has been much discussion of so-called "universal Darwinism". Dawkins' dual aim was to reduce evolutionary phenomena to the level of the gene, while at the same time abstracting the Darwinian process of natural selection of "replicators" and making it into something that would apply beyond the domain of biology.

Why Jerry Fodor and Massimo Piattelli-Palmarini are wrong about Darwin and evolution.

Di Massimo di Tiro si conoscono pochi dettagli biografici. Le fonti antiche, concordi nel ritenerlo ‘filosofo’ e ‘filosofo platonico’, affermano che le sue dissertazioni o indagini filosofiche sono da ricondursi al suo primo soggiorno a Roma, al tempo dell’imperatore Commodo. Le quarantuno dissertazioni filosofiche di Massimo di Tiro offrono una visione privilegiata della cultura imperiale del secondo secolo, epoca in cui, dominante l’eleganza stilistica, anche la filosofia non disdegnava di dispiegare i propri contenuti mediante il bello stilo dello (...) strumento retorico. Nello svolgimento dei temi, perlopiù platonici nell’ispirazione e orientati ad argomenti presenti al dibattito coevo, ma comunque non escludenti altre influenze filosofiche, Massimo di Tiro si mostra pensatore dalla non banale semplicità. Muovendosi fra filosofia e letteratura, fra Platone e Omero, egli calibra l’erudizione sul filtro di un’esigenza educativa di ampio respiro. Nel volume si presenta la prima traduzione italiana completa dal greco. Il commento critico, aggiornato al dibattito accademico internazionale, mira a mostrare come l’opera del pensatore meriti una rinnovata attenzione nell’ambito degli studi classici letterari e filosofici, giacché nel delineare il quadro culturale del tempo essa consente di meglio precisare alcuni non marginali aspetti del platonismo del secondo secolo.

Stoicism Stoicism originated as a Hellenistic philosophy, founded in Athens by Zeno of Citium, c. 300 B.C.E. It was influenced by Socrates and the Cynics, and it engaged in vigorous debates with the Skeptics, the Academics, and the Epicureans. It moved to Rome where it flourished during the period of the Empire, … Continue reading Stoicism →.

This contribution offers a reflection on the death penalty in the light of OT Law that enforced and sanctioned it only within the scope of the biblical understanding of justice. Starting therefore with the Torah and moving through the Prophets into the New Testament, the reader is called to question the logic behind retributive justice, as it attempts to re-establish the desecrated order. Retributive justice does so by means of a 'just' punishment, by giving everyone one's due, and through the (...) emendation of the culprit. The cross, though, goes well beyond the understanding of God as symmetry and the concept of a 'matching' justice. In Christ's death, the first place cannot be accorded to an order that needs to be set right again; still less can it be given to the suppression of bad subjects. That first place must belong to the human person who cries out for redemption and asks to be re-created in God's image. This would amount to nothing less than a restitutio principii. (shrink)

We present an account of semantics that is not construed as a mapping of language to the world but rather as a mapping between individual meaning spaces. The meanings of linguistic entities are established via a “meeting of minds.” The concepts in the minds of communicating individuals are modeled as convex regions in conceptual spaces. We outline a mathematical framework, based on fixpoints in continuous mappings between conceptual spaces, that can be used to model such a semantics. If concepts are (...) convex, it will in general be possible for interactors to agree on joint meaning even if they start out from different representational spaces. Language is discrete, while mental representations tend to be continuous—posing a seeming paradox. We show that the convexity assumption allows us to address this problem. Using examples, we further show that our approach helps explain the semantic processes involved in the composition of expressions. (shrink)

The analysis of Hannah Arendt's Socrate opens up the possibility of a fruitful rethinking of the sense and way of conceiving philosophy with children. A way that in this proposal is defined as "Utopian", since it intends to resume, with the Socratic lesson, just how much remains in it open, undetermined, capable of reviving with enchantment in the living of the orality of a philosophical dialogue- absolutely unprecedented and unpredictable - such as that with children. The space given to the (...) unexpected, to listening, to free divergence, then becomes radical, comes to be a paradoxical foundation of a "methodology" that cannot be captured in structured schemes and paths, since it remains open to the "utopian" space of philosophizing. The comparison with Arendt is therefore interleaved, through references to other readings that are contemporary of the Socratic lesson, with the experience lived of the author, who has been leading for years philosophy workshops with primary school children. Of course, Socrates has never been and never wanted to act as a "master": his conducting the dialogue, although always being asymmetric, is aimed at bringing the interlocutor on his line of reasoning and never the opposite, has never had as end the teaching of some doctrine. How much, rather, to lead the interlocutor from the presumed certainty to radical uncertainty, from opinion to doubt, from affirmation to aporia. Thiswe must authentically experiment, before anything else, when we place ourselves inlistening to children's questions, when we try to dialogue with them, to "do philosophy", to "think together".
