This paper analyses the structure of evolutionary theory as a quasi-Newtonian theory and the need to establish a Zero-Cause Law. Several authors have postulated that the special character of drift is because it is the default behaviour or Zero-Cause Law of evolutionary systems, where change and not stasis is the normal state of them. For these authors, drift would be a Zero-Cause Law, the default behaviour and therefore a constituent assumption impossible to change without changing the system. I defend that (...) drift's causal and explanatory power prevents it from being considered as a Zero-Cause Law. Instead, I propose that the default behaviour of evolutionary systems is what I call the Principle of Stasis, which posits that an evolutionary system where there is no selection, drift, mutation, migration, etc., and therefore no difference-maker, will not undergo any change (it will remain in stasis).

This article analyzes the view of evolutionary theory as a theory of forces. The analogy with Newtonian mechanics has been challenged due to the alleged mismatch between drift and the other evolutionary forces. Since genetic drift has no direction several authors tried to protect its status as a force: denying its lack of directionality, extending the notion of force and looking for a force in physics which also lacks of direction. I analyse these approaches, and although this strategy finally succeeds, (...) this discussion overlooks the crucial point on the debate between causalists and statisticalists: the causal status of evolutionary theory.

This paper provides a philosophical analysis of the Price equation and its role in evolutionary theory. Traditional models in population genetics postulate simplifying assumptions in order to make the models mathematically tractable. On the contrary, the Price equation implies a very specific way of theorizing, starting with assumptions that we think are true and then deriving from them the mathematical rules of the system. I argue that the Price equation is a generalization-sketch, whose main purpose is to provide a unifying (...) framework for researchers, helping them to develop specific models. The Price equation plays this role because, like other scientific principles, shows features as abstractness, unification and invariance. By underwriting this special role for the Price equation some recent disputes about it could be diverted. (shrink)

Due to its high degree of complexity and its historical nature, evolutionary biology has been traditionally portrayed as a messy science. According to the supporters of such a view, evolutionary biology would be unable to formulate laws and robust theories, instead just delivering coherent narratives and local models. In this article, our aim is to challenge this view by showing how the Price equation can work as the core of a general theoretical framework for evolutionary phenomena. To support this claim, (...) we outline some unnoticed structural similarities between physical theories and evolutionary biology. More specifically, we shall argue that the Price equation, in the same way as fundamental formalisms in physics, can serve as a heuristic principle to formulate and systematise different theories and models in evolutionary biology.

In this paper, we address the question whether a mechanistic approach can account for evolutionary causes. The last decade has seen a major attempt to account for natural selection as a mechanism. Nevertheless, we stress the relevance of broadening the debate by including the other evolutionary causes inside the mechanistic approach, in order to be a legitimate conceptual framework on the same footing as other approaches to evolutionary theory. We analyse the current debate on natural selection as a mechanism, and (...) extend it to the rest of the evolutionary causes. We focus on three approaches that we call the stochastic view, the functional view, and the minimalist view. We argue that all of them are unable to account for evolutionary causes as mechanisms. It is concluded that the current mechanistic proposals cannot be accepted as a common framework for evolutionary causes. Finally, we outline some guidelines and requirements that any mechanistic proposal should meet in order to be applied to evolutionary theory. (shrink)

The Price equation is currently considered one of the fundamental equations —or even the fundamental equation— of evolution. In this article, we explore the role of this equation within cultural evolutionary theory. More specifically, we use it to account for the explanatory power and the theoretical structure of a certain generalised version of dual-inheritance theory. First, we argue that, in spite of not having a definite empirical content, the Price equation offers a suitable formalisation of the processes of cultural evolution, (...) and provides a powerful heuristic device for discovering the actual causes of cultural change and accumulation. Second, we argue that, as a consequence of this, a certain version of the Price equation is the fundamental law of cultural evolutionary theory. In order to support this claim, we sketch the ideal structure of dual-inheritance theory and we stress the unificatory role that the Price equation plays in it. (shrink)

Psychological characteristics of athletes play a key role in sport performance and may moderate and mediate the influence of technical, tactical, and physical abilities athletes show. Different authors have emphasized the special attention such psychological characteristics should receive considering the extent they can influence athletes’ behavior either in training or in competition. This paper is aimed at describing the psychological profiles of two cycling sports: triathlon and road cycling. One hundred and twenty-nine male and female professional and amateur cycling athletes (...) (35.74 years old average age ±12.79; 14.94 average number of years practicing cycling ±11.20) were assessed on different psychological characteristics. For that purpose, the Psychological Characteristics related to the Sport Performance (CPRD) Questionnaire and the Psychological Skills Inventory for Sports (PSIS) was used. Results showed significant differences among triathlon and road cyclists (Stress control = t 116 =-3.711, p = 0.000, d = 0.48 ; Influence of Performance Evaluation = t 115 =-3-115, p = 0.002, d = 0.49; Motivation = t 124 =-5.520, p = 0.000, d = 0.82; Mental Skills = t 119 =-4.985, p = 0.000, d = 1.02). There were no significant differences between men and women though there were differences among pros and amateur athletes. Triathlon professional, compared to amateurs, showed higher scores in all the psychological dimensions assessed (Stress control = t 85 = 3.005, p = 0.003, d = 1.07; Influence of Performance Evaluation = t 83 = 2.858, p = 0.005, 0.77; Motivation = t 91 = 2.721, p = 0.008, d = 0.26; Mental Skills = t 87 = 2.556, p = 0.012, d = 0.77). The results of this descriptive study contribute to establishing a model of optimal psychological profiling applied to the different cycling groups that can be used by sport psychologist, trainers, and coaches in order to promote peak performance of these athletes.

The Price equation provides a comprehensive representation of evolutionary processes. Since its original formulation by George Price, it has been used to model a variety of phenomena in quantitative genetics and related fields. However, there is no consensus on the explanatory power of the equation. In this article we aim to clarify its place within modern evolutionary theory. To this end, we first state the basic concepts from which the Price equation can be derived as a theorem. From this axiomatization, (...) we conclude that the Price equation is not explanatory in itself. It merely provides a phenomenological description of evolutionary processes. We argue that its role is analogous to that of Galilean kinematics in classical mechanics. Both the Price equation and Galilean kinematics function as conceptual frameworks that define the basic features of the behavior of a class of systems. Practitioners are encouraged to theorize further on these frameworks to find the possible explanation of this behavior in various specific scenarios. Thus, despite its phenomenological character, the Price equation integrates different fields of evolutionary biology by providing a common formalization of their shared explanandum. (shrink)

In this work, originally published in 1986, Victor Seidler explores the different notions of respect, equality and dependency in Kant’s moral writings. He illuminates central tensions and contradictions not only within Kant’s moral philosophy, but within the thinking and feeling about human dignity and social inequality which we take very much for granted within a liberal moral culture. In challenging our assumption of the autonomy of morality, Seidler also questions our understanding of what it means for someone to live as (...) a person in his or her own right. The autonomy of individuals cannot be assumed but has to be reasserted against relationships of subordination. This involves a break with a rationalist morality, so that respect for others involves respect for emotions, feelings, desires and needs, and establishes a fuller autonomy as a basis for freedom and justice.

This chapter contains sections titled: Notes.

Wittgenstein's later philosophy is usually characterized as pragmatist, his account of linguistic meaning as conventionalist, and his methodology as naturalistic. Wittgenstein is said to have renounced in the later work his early concern with the Unsayable, and to have relocated philosophy within the realm of discourse. I argue against that picture of Wittgenstein's later philosophy in this dissertation. ;The central insight of Wittgenstein's discussion of rules and language in the Investigations is that meaning is not the result of a cognitive (...) achievement, but that it is grounded in precognitive natural reactions common to all human beings. I show that the appeal to the precognitive is transcendental, for it involves reference to a synthesis that is prior to discursive articulation and presupposed as a necessary condition of meaning. ;I argue against the conventionalist reading of Wittgenstein that the transcendental appeal to precognitive reactions in the discussion of rules is distinct from the appeal to a social context in the Private Language Argument, and that the relation between those two discussions is analogous to that between Kant's Transcendental Deduction and the Refutation of Idealism. ;The parallel with Kant helps to show how the failure to distinguish the empirical and transcendental levels in Wittgenstein's discussion leads to the conventionalist readings of his account of language . . It also shows that Wittgenstein is not subject to the charge of relativism commonly levelled against him . ;The distinction between empirical and transcendental levels, as it appears in the pivotal notion of Form of Life, reveals that Wittgenstein's methodology is not naturalistic but instead depends on a non-discursive mode of awareness. . I argue on this basis that Wittgenstein is closer to intuitive-realists than to pragmatists . ;Wittgenstein's Transcendentalism thus shows a deep continuity between the motivations behind his early and his later thought. In fact, the Unsayable plays a central role in the later work, for it is through non-discursive insight into the Unsayable that philosophy fulfills the therapeutic task that Wittgenstein assigns to it in the Investigations.

Taking a Harder Line “The New Atheism” is the name that was attached, often pejoratively, to the series of six bestselling books by five authors that appeared in the period 2004-2008.[i] Since then many have joined the movement, with an upsurge in books, freethinker organizations, and an exponential expansion of the blogosphere spreading the word on atheism to thousands. The message of new atheism is that it is time to take a far less accommodating attitude toward religion, including moderate religion, (...) than had been exhibited in previous years by atheist authors and, in particular, non-believing scientists. Science, in the United States, is locked in a battle with conservative Christians over the teaching of evolution and creationism in the schools. While 87 percent of scientists accept evolution by unguided, purely natural processes, only 32 percent of the public does.[ii] Belief in unguided evolution among mainline Protestants and Catholics is about the same as among the general public, while only 10 percent of Evangelicals and 19 percent of Fundamentalist Protestants acknowledge this view.

In this fascinating and accessible book, physicist Victor J. Stenger guides the lay reader through the key developments of quantum mechanics and the debate over its apparent paradoxes. In the process, he critically appraises recent metaphysical fads. Dr. Stenger's knack for elucidating scientific ideas and controversies in language that the nonspecialist can comprehend opens up to the widest possible audience a wealth of information on the most important findings of contemporary physics.

Why does symbolic communication in humans develop primarily in an oral medium, and how do theories of language origin explain this? Non-human primates, despite their ability to learn and use symbolic signs, do not develop symbols as in oral language. This partly owes to the lack of a direct cortico-motoneuron control of vocalizations in these species compared to humans. Yet such modality-related factors that can impinge on the rise of symbolic language are interpreted differently in two types of evolutionary storylines. (...) 1) Some theories posit that symbolic language originated in a gestural modality, as in “sign languages”. However, this overlooks work on emerging sign and spoken language showing that gestures and speech shape signs differently. 2) In modality-dependent theories, some emphasize the role of iconic sounds, though these lack the efficiency of arbitrary symbols. Other theorists suggest that ontogenesis serves to identify human-specific mechanisms underlying an evolutionary shift from pitch varying to orally-modulated vocalizations (babble). This shift creates numerous oral features that can support efficient symbolic associations. We illustrate this principle using a sound-picture association task with 40 learners who hear words in an unfamiliar language (Mandarin) with and without a filtering of oral features. Symbolic associations arise more rapidly and accurately for sounds containing oral features compared to sounds bearing only pitch features, an effect also reported in experiments with infants. The results imply that, beyond a competence to learn and use symbols, the rise of symbolic language rests on the types of signs that a modality of expression affords. (shrink)

Over-flexibility in the definition of Friston blankets obscures a key distinction between observational and interventional inference. The latter requires cognizers form not just a causal representation of the world but also of their own boundary and relationship with it, in order to diagnose the consequences of their actions. We suggest this locates the blanket in the eye of the beholder.

Two hundred and twenty-six state employees completed a structured questionnaire that investigated their ethical values and training needs. Top management were more likely to have attitudes against cronyism and giving advantage to others. Individuals higher in the organizational hierarchy, and female employees were more likely to believe that discriminatory practices were an ethical concern. In addition, employees with a larger number of clients outside of the organization were more supportive of the need to maintain strict confidentiality in business dealings. Employees'' (...) awareness and use of the organization''s code of conduct generally proved to be poor predictors of ethical values. Other analyses revealed that a variety of sociodemographic factors, job characteristics and ethical values predicted specific areas of training needs in ethics. (shrink)

While belief in gods was almost universal in the ancient world, Thales of Miletus introduced the notion that observed phenomena could be explained in natural terms without invoking imagined spirits. Leucippus and Democritus, and later Epicurus and Lucretius, proposed that everything was composed of particulate atoms in an otherwise empty void. Any gods that existed played no role in the human world. The universe was infinite, eternal, uncreated, and included many worlds besides our own. These ideas conflicted with the other (...) philosophical schools of the time and were suppressed by the Church during the Dark Ages. Atomism reappeared during the Renaissance and became a crucial ingredient in the scientific revolution that followed. The atomic picture of matter has now been solidly confirmed. Furthermore, the notion of an infinite, eternal, and uncreated ‘multiverse’ is strongly suggested by modern cosmology. (shrink)

“Wittgenstein’s Ghosts. Between Deleuze and Derrida”. Both Derrida and Deleuze agree that with the advent of the moving image and the art of film, we need to articulate a new ontology or –in Wittgenstein’s terms–, a new grammar. Derrida suggests this much when he reflects on what he calls the return of ghosts, which he attributes to the advent of film and the communications media; Deleuze does the same in his studies of film, and in particular in what he calls (...) the time-image. They both carve a grammatical space where room is opened for us to talk about an experience that fuses, paradoxically, problematically, the real and the virtual. Wittgenstein is tracing this grammar in his discussions on inner experience and in his observations about the phenomenon of aspect-seeing. Articulating a new grammar requires also a new way of seeing and this new seeing is the purpose of his methods; “clairvoyant” methods we can call them, following Deleuze’s term for what the time image propitiates in the viewer, in that they allow us to see beyond things to their aspects, beyond substances to processes; in other words, they train us to think in moving time. Philosophy is thus always a work of mourning and a commerce with ghosts. What this means is that Wittgenstein is –as Derrida and Deleuze are too–, what we might call a philosopher of becoming.

The claim that certain fundamental constants of nature are fine tuned for life and that this provides strong evidence for supernatural design is perhaps the best scientific argument for the existence of God since Paley’s watch. Even atheist physicists find these so called “anthropic coincidences” difficult to explain and need to invoke the Weak Anthropic Principle and multiple universes to do so. Certainly if there are many universes, fine tuning is simple. Our form of life was fined tuned to our (...) universe by evolution. While multiple universes are expected from modern cosmological theories, theists and some scientists object that invoking the unobservable is not science. Of course, God is unobservable too, so the best theists can claim is a standoff. This is the first in a series of columns based on a book in the works that attempts to show that the apparent fine tuning of fundamental constants can be understood from basic physics without invoking multiple universes. In some cases the explanation is provable. In other cases, it is not provable but plausible. Fine tuning by design is a God of the Gaps argument. The proponent has the burden if proving that no possible natural explanation can be found. Thus a plausible natural explanation is sufficient to defeat the argument. A list of thirty four parameters that seem to be fine tuned has been assembled by Rich Deem on the God and Science website. Several of Deem’s constants, such as the speed of light in a vacuum, c, Newton’s constant of gravity, G, and Planck’s constant, h, are just arbitrary numbers that are determined simply by the unit system you are using. They can be set equal to any number you want, except zero, with no impact on the physics. So no fine tuning can possibly be involved, just as the number p is not fine tuned. I will focus first on the five parameters that have the most significance because, if interpreted correctly, they seem to pretty much rule out almost any conceivable kind of life without fine tuning: · Ratio of electrons to protons · Ratio of electromagnetic force to gravity Expansion rate of the universe · Mass density of the universe · Cosmological constant I will admit that the features a universe would have for slightly different values of these parameters, all other parameters remaining the same, would render unlikely any form of life even remotely like ours, that is, one that is based on a lengthy process, chemical or otherwise, by which complex matter evolved from simpler matter. Let me discuss each in turn, with the last, the most difficult, reserved for a future column.. (shrink)

“¿Principio de caridad o hybris?” La intuición de Wittgenstein, de que el significado lingüístico se constituye dentro de la trama de vida pareciera hacer posible un acercamiento entre la tradición hermenéutica continental y la filosofía analítica del lenguaje.

Sin esa reconcepción, el principio de caridad se convierte en una forma encubierta de (...) imperialismo conceptual incompatible con el espíritu de la hermenéutica continental.

Our understanding of the face is deeply entrenched in ocular-centrism and anthropocentric narcissism, limiting the recognition of faceness to humans alone. This restricted perspective undermines our ethical engagement with the non-human world and sustains an illusion of stability and control, blinding us to our existential fragility and diminishing our ability to address the profound challenges of the Anthropocene. Drawing on speculative realism, this essay seeks to transcend these limitations by reimagining the concept of the face as a dynamic, relational phenomenon. (...) By broadening our discernment of faceness beyond the human, we aim to foster a more attuned and ethically responsive orientation toward the interconnected realities of our era. (shrink)

The Digital Revolution is transforming the way in which we interact with one another and relate to experience. The superabundance and superfluity of the virtual world, the fleeting moment and instantaneous pleasure it provides, begin to prevail as a cultural value and determine an attitude of detachment and indifference that extends to all aspects of our life. For Søren Kierkegaard this is a “demoniacal temptation” that leads to a life devoid of spiritual depth. In the midst of the undeniable bounties (...) of technology, reflection on this paradoxical nature of the technological in our lives becomes an urgent task. (shrink)

I show that the latter Wittgenstein's treatment of language and the mind results in a conception of the human subject that goes against the exclusive emphasis on the cognitive that characterizes our modern conception of knowledge and the self. For Wittgenstein, our identification with the cognitive ego is tantamount to a blindness to our own nature — blindness that is entrenched in our present culture. The task of philosophy is thus transformed into a form of cultural therapy that seeks to (...) awaken in us a sensitivity to different modes of awareness than the merely intellectual. Its substance of reflection becomes not only the field of conscious rational thought, but the tension in our nature between reason and vital feeling, that is, between culture and life. (shrink)

D’Souza claims that near-death experiences (NDE) suggest that consciousness can outlive the breakdown of the body and cannot be explained as the product of dying brains. These experiences can be found in situations where a subject is not near death and have all the characteristics of hallucinations caused by oxygen deprivation. Despite thousands of cases, no one has every come back from an NDE with information that could not have been in their heads originally.

By the late nineteenth century, science was well established in the public mind as the primary method by which useful knowledge of the material universe is obtained. Surely, it was thought, if science can discover cathode rays and radio waves, then it should easily authenticate a phenomenon that is far more widely experienced: the supernatural power of the human mind. Non-physical, “psychic” energy appeared to be everywhere, as an integral part of human experience. Indeed, psychic forces are seemingly built into (...) the cores, the souls, of each of us. It should be just a matter of securing the evidence with the hard cement of scientific procedure. At least this was the view of many Victorian scientists, and so was begun a program to verify psychic phenomena scientifically, a task that has continued without success until the current day. By the time the fourth decade of the twentieth century was underway, the search for psychic energy had stalled. The huge database of anecdotal human testimony proved too unreliable, too easy to explain away as subjective desire, fakery, or delusion. Whenever serious attempts were made to gather objective data under controlled conditions, plausible explanations such as trickery or simple coincidence were readily found--if not by the investigators, then by their critics. Although these plausibilities were not always conclusively proven, they were never conclusively ruled out. And, as long as ordinary explanations for reports of suggested psychic phenomena.. (shrink)

There has been a longstanding bias in the study of spoken language towards using writing to analyse speech. This approach is problematic in that it assumes language to be derived from an autonomous mental capacity to assemble words into sentences, while failing to acknowledge culture-specific ideas linked to writing. Words and sentences are writing constructs that hardly capture the sound-making actions involved in spoken language. This book brings to light research that has long revealed structures present in all languages but (...) which do not match the writing-induced concepts of traditional linguistic analysis. It demonstrates that language processes are not physiologically autonomous, and that speech structures are structures of spoken language. It then illustrates how speech acts can be studied using instrumental records, and how multisensory experiences in semantic memory couple to these acts, offering a biologically-grounded understanding of how spoken language conveys meaning and why it develops only in humans.

Studies of individuals under conditions of confinement or severe social and physical restrictions have consistently shown deleterious mental health effects but also high levels of adaptability when dealing with such conditions. Considering the role of physical activity and sport in psychological adaptation, this paper describes a longitudinal study to explore to what extent the imposed restrictions due to the outbreak of SARS-CoV-2 may have affected athletes’ mental health outcomes and how far the process of adaptation to confinement conditions is differentially (...) affected depending on whether the sports activity was practiced individually or in a group, and outdoors, indoors, or both. Two hundred and seventy-four athletes were assessed over 7 weeks using the GHQ-28 and an ad hoc survey exploring the practice of physical activity. A mixed-model fixed effects ANCOVA was used to analyze the effects of time, place, and company in which the sport was practiced, with an index of the amount of physical activity expended as a covariate. Results show a significant effect of time in three out of four of the GHQ-28 subscales, in all cases showing a consistent adaptation to conditions over time. Results also show that playing sport indoors, outdoors, or both, and practicing alone vs. with others differentially affect the somatic symptoms exhibited during confinement: Athletes who practiced sport with others showed higher levels of somatic symptoms at the beginning of the set of data but a quicker rate of adaptation. Differences arising from practicing sport alone or with others were more pronounced in the case of indoor sports, which could be related to the fact that physical activity that can be practiced during confinement is more similar to that practiced indoors alone. Implications relating to what sport psychologists and other health professionals may offer to athletes in stressful situations are discussed. (shrink)
