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.

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.

Presents a comprehensive history of multiverse theory, reviewing the discoveries that shaped astrophysicists' current consensus view while showing that the multiverse is able to be explained entirely in naturalistic terms.

The story of a triumphant idea from Democritus to the Higgs boson, one of the most successful scientific hypotheses ever devised is chronicled in this history of atomism. Stenger makes the case that in the final analysis atoms and the void are all that exists.

A pioneer in the field of behavioral science delivers a groundbreaking work that shows how finding your purpose in life leads to better health and overall happiness.Your life is a boat. You need a rudder. But it doesn't matter how much wind is in your sails if you're not steering toward a harbor--an ultimate purpose in your life.While the greatest philosophers have pondered purpose for centuries, today it has been shown to have a concrete impact on our health. Recent studies (...) into Alzheimer's, heart disease, stroke, depression, functional brain imaging, and measurement of DNA repair are shedding new light on how and why purpose benefits our lives.Going beyond the fads, opinions, and false hopes of "expert" self-help books, The Science of Purpose explores the incredible connection between purposeful living and the latest scientific evidence on quality of life and longevity. Drawing on ancient and modern philosophy, literature, psychology, evolutionary biology, genetics, and neuroscience, as well as his experience in public health research, Dr. Vic Strecher reveals the elements necessary for a purposeful life and how to acquire them, and outlines an elegant strategy for improving energy, willpower, and long-term happiness, and well-being. He integrates these core themes into his own personal story--a tragedy that led him to reconsider his own life--and how a deeper understanding of purposeful living helped him not only survive, but thrive.Illuminating, accessible, and authentically grounded in real people's experiences, The Science of Purpose is essential reading for everyone seeking lasting improvement in their lives.

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)

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)

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)

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. (shrink)

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).

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.

Argues that many claims by theists are based on their misunderstanding of science. He looks at the specific parameters and shows that plausible reasons can be found for the values they have within the existing standard models of physics and cosmology.

Many theists regard the claim that certain fundamental constants of nature are fine-tuned for life as 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 naturally and many think they need to invoke multiple universes and the so-called “anthropic principle” to do so. Certainly if there are many universes, fine-tuning is simple. Our universe is not fine-tuned for life. Life is fine-tuned to our universe. 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. (shrink)

I INTRODUCTION: RESPECT, EQUALITY AND THE AUTONOMY OF MORALITY We often invoke a notion of respect to express our sense of human equality. ...

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)

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.

“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 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)

This book is a psychoanalytic and philosophical exploration of how the digital is transforming our perception of the world and our understanding of ourselves. Drawing on examples from everyday life, myth, and popular culture, this book argues that virtual reality is only the latest instantiation of the phenomenon of the virtual, which is intrinsic to human being. It illuminates what is at stake in our understanding of the relationship between the virtual and the real, showing how our present technologies both (...) enhance and diminish our psychological lives. The authors claim that technology is a pharmakon --at the same time both a remedy and a poison-- and in their writing exemplify a method that overcomes the polarization that compels us to regard it either as a liberating force or a dangerous threat in human life. The digital revolution challenges us to reckon with the implications of what is being called our posthuman condition, leaving behind our modern conception of the world as constituted by atemporal essences and reconceiving it instead as one of processes and change. The book's postscript considers the sudden plunge into the virtual effected by the 2020 global pandemic. Accessible and wide-reaching, this book will appeal not only to psychotherapists, psychoanalysts, and philosophers, but anyone interested in the ways virtuality and the digital are transforming our contemporary lives.

The anthropic coincidences are widely claimed to provide evidence for intelligent creation in the universe. However, neither data northeory support this conclusion. No basis exists for assuming that a random universe would not have some kind of life. Calculations of the properties of universes having different physical constants than ours indicate that long-lived stars are not unusual, and thus most universes should have time for complex systems of some type to evolve. A multi-universe scenario is not ruled out, since no (...) known principle requires that only one universe exist. (shrink)

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)

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.

This thought-provoking book, first published in 1991, examines sexual politics in a world which is being radically changed by the challenges of feminism. Seidler explores how men have responded to feminism, and the contradictory feelings men have towards dominant forms of masculinity. Seidler’s stimulating and original analysis of social and political theory connects personally to everyday issues in people’s lives. It reflects the growing importance of sexual and personal politics within contemporary politics and culture, and demonstrates clearly the challenge that (...) feminism brings to our inherited forms of morality, politics and sexuality.

“¿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. En el presente artículo se sostiene que esta intuición debe ir acompañada de una revisión de la concepción del sujeto implícita en el “principio de caridad” de Donald Davidson. Sin esa reconcepción, el principio de caridad se convierte en una forma encubierta de (...) imperialismo conceptual incompatible con el espíritu de la hermenéutica continental. Se concluye el artículo con algunas observaciones sobre el relativismo a la luz de las consideraciones anteriores. (shrink)

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)
