For over a century, Haeckel's Gastraea theory remained a dominant theory to explain the origin of multicellular animals. According to this theory, the animal ancestor was a blastula‐like colony of uniform cells that gradually evolved cell differentiation. Today, however, genes that typically control metazoan development, cell differentiation, cell‐to‐cell adhesion, and cell‐to‐matrix adhesion are found in various unicellular relatives of the Metazoa, which suggests the origin of the genetic programs of cell differentiation and adhesion in the root of the Opisthokonta. Multicellular (...) stages occurring in the complex life cycles of opisthokont protists (mesomycetozoeans and choanoflagellates) never resemble a blastula. Here, we discuss a more realistic scenario of transition to multicellularity through integration of pre‐existing transient cell types into the body of an early metazoon, which possessed a complex life cycle with a differentiated sedentary filter‐feeding trophic stage and a non‐feeding blastula‐like larva, the synzoospore. Choanoflagellates are considered as forms with secondarily simplified life cycles. (shrink)

A generic extension of the constructible universe by reals is defined, in which the union of ‐classes of x and y is a lightface set, but neither of these two ‐classes is separately ordinal‐definable.

The parameter-free part $$\textbf{PA}_2^*$$ of $$\textbf{PA}_2$$, second order Peano arithmetic, is considered. We make use of a product/iterated Sacks forcing to define an $$\omega $$ -model of $$\textbf{PA}_2^*+ \textbf{CA}(\Sigma ^1_2)$$, in which an example of the full Comprehension schema $$\textbf{CA}$$ fails. Using Cohen’s forcing, we also define an $$\omega $$ -model of $$\textbf{PA}_2^*$$, in which not every set has its complement, and hence the full $$\textbf{CA}$$ fails in a rather elementary way.

We propose a canonization scheme for smooth equivalence relations on Rω modulo restriction to E0-large infinite products. It shows that, given a pair of Borel smooth equivalence relations E, F on Rω, there is an infinite E0-large perfect product P⊆Rω such that either F⊆E on P, or, for some ℓ<ω, the following is true for all x,y∈P: xEy implies x(ℓ)=y(ℓ), and x↾(ω∖{ℓ})=y↾(ω∖{ℓ}) implies xFy.

It is true in the Cohen, Solovay-random, dominaning, and Sacks generic extension, that every countable ordinal-definable set of reals belongs to the ground universe. It is true in the Solovay collapse model that every non-empty OD countable set of sets of reals consists of \ elements.

The research presented in this paper was motivated by our aim to study a problem due to J. Bourgain [3]. The problem in question concerns the uniform boundedness of the classical separation rank of the elements of a separable compact set of the first Baire class. In the sequel we shall refer to these sets (separable or non-separable) as Rosenthal compacta and we shall denote by ∝(f) the separation rank of a real-valued functionfinB1(X), withXa Polish space. Notice that in [3], (...) Bourgain has provided a positive answer to this problem in the case ofKsatisfyingwithXa compact metric space. The key ingredient in Bourgain's approach is that whenever a sequence of continuous functions pointwise converges to a functionf, then the possible discontinuities of the limit function reflect a local ℓ1-structure to the sequence (fn)n. More precisely the complexity of this ℓ1-structure increases as the complexity of the discontinuities offdoes. This fruitful idea was extensively studied by several authors (c.f. [5], [7], [8]) and for an exposition of the related results we refer to [1]. It is worth mentioning that A.S. Kechris and A. Louveau have invented the rank rND(f) which permits the link between thec0-structure of a sequence (fn)nof uniformly bounded continuous functions and the discontinuities of its pointwise limit. Rosenthal'sc0-theorem [11] and thec0-index theorem [2] are consequences of this interaction.Passing to the case where either (fn)nare not continuous orXis a non-compact Polish space, this nice interaction is completely lost.

Activating Transcription Factor-2 is a sequence-specific DNA-binding protein that belongs to the bZIP family of proteins and plays diverse roles in the mammalian cells. In response to stress stimuli, it activates a variety of gene targets including cyclin A, cyclin D and c-jun, which are involved in oncogenesis in various tissue types. ATF-2 expression has been correlated with maintenance of a cancer cell phenotype. However, other studies demonstrate an antiproliferative or apoptotic role for ATF-2. In this review, we summarize the (...) signaling pathways that activate ATF-2, as well as its downstream targets. We examine the role of ATF-2 in carcinogenesis with respect to other bZIP proteins, using data from studies in human cancer cell lines, human tumours and mouse models, and we propose a potential model for its function in carcinogenesis, as well as a theoretical basis for its utility in anticancer drug design.

Sex steroids, through their receptors, have potent effects on the signal pathways involved in osteogenic or myogenic differentiation. However, a considerable segment of those signal pathways has a prominent role in epithelial neoplastic transformation. The capability to intervene locally has focused on specific ligands for the receptors. Nevertheless, many signals are mapped to interactions of steroid receptor motifs with heterologous regulatory proteins. Some of those proteins interact with the glucocorticoid receptor and other factors essential to cell fate. Interactions of steroid (...) receptor domain motifs with heterologous proteins affect specific target pathways; consequently, manipulation of specified protein modules complexed with steroid receptors may be a next major step for enhancing molecular targeted therapeutics. In the future, intervention at specific sections of receptor primary sequence may prove therapeutically more efficient in targeting pathways of choice than ligand selectivity can be. (shrink)

In the last part of the Timaeus, where Plato presents his ideas about human physiology but also about biology in general, we find the combined activity of Intellect and Necessity. In this essay I investigate whether Plato, apart from his general statement about the combined activity of Reason and Necessity, proposes a more specific method of biological research. For this purpose I am going to examine some methodological passages as well as the way in which he exposes and develops his (...) views about the human body and its organs. (shrink)

Categorical Monism (that is, the view that all fundamental natural properties are purely categorical) has recently been challenged by a number of philosophers. In this paper, I examine a challenge which can be based on Gabriele Contessa’s [10] defence of the view that only powers can confer dispositions. In his paper Contessa argues against what he calls the Nomic Theory of Disposition Conferral (NTDC). According to NTDC, in each world in which they exist, (categorical) properties confer specific dispositions on their (...) bearers; yet, which disposition a (categorical) property confers on its bearers depends on what the (contingent) laws of nature happen to be. Contessa, inter alia, rests his case on an intuitive analogy between cases of mimicking (in which objects do not actually possess the dispositions associated with their displayed behaviour) and cases of disposition conferral through the action of laws. In this paper, I criticize various aspects of Contessa’s argumentation and show that the conclusion he arrives at (that is, only powers can confer dispositions) is controversial. (shrink)

This book explores the dispositional and categorical debates on the metaphysics of properties. It defends the view that all fundamental properties and relations are contingently categorical, while also examining alternative accounts of the nature of properties. Drawing upon both established research and the author's own investigation into the broader discipline of the metaphysics of science, this book provides a comprehensive study of the many views and opinions regarding a most debatable topic in contemporary metaphysics.

The bulk of the literature concerning the governing role of non-Humean laws has been concentrated on the alleged incapability of higher order nomic facts to determine the regularities in the behaviour of actual objects, the so-called Inference Problem. Most recently Ioannidis, Livanios and Psillos (2021) argue that an adequate solution to the Inference Problem requires an answer to the question of how nomic relations manage to ‘tell’ properties what to do. Ioannidis et al. dub the difficulty that all extant accounts (...) of governing laws face to give such an answer, the Governing Problem and introduce a Dualist Model, according to which the specific behaviour of things in the world is the outcome of both the thin powers things have to be subjected to laws, and certain nomic features of the world. The aim of this paper is to show that the most plausible form of the Dualist Model can provide the basis for a novel version of the Powerful Qualities View about properties. To this end it presents ways of developing two aspects of the Dualist Model. It defends the view that nomic relations must be relata-specific in order to play their theoretical role within the Model and provides arguments for the view that natural properties should have the minimum (compatible with the core tenets of the Model) modal strength.

Dans la littérature ascétique, orgueil et humilité sont considérés comme la matrice, respectivement, de tous les vices et de toutes les vertus. En outre, travailler sur les autres vertus ainsi que sur l’humilité elle-même risque de nourrir l’orgueil. Le présent article confronte ces perspectives avec des recherches récentes en psychologie du comportement moral et de la personnalité qui ont investigué sur le narcissisme, l’estime de soi, la modestie et l’humilité. Il poursuit un triple objectif. Primo, examiner la pertinence des conceptions (...) de la littérature ascétique sur le caractère pluridimensionnel de l’orgueil et de l’humilité: rapport à soi, aux autres, et à Dieu. Secundo, examiner si la valorisation religieuse de l’humilité se traduit effectivement dans les attitudes et comportements des croyants par une modestie et une humilité plus grande. Tertio, proposer des pistes qui permettent d’envisager sereinement le combat spirituel contre l’orgueil de manière à éviter les vicissitudes qui lui sont inhérentes ou associées: narcissisme caché, déresponsabilisation, culpabilisme excessif, fausse humilité et compensation par un altruisme égoïste.

Is not trying to define uniqueness somehow an aberration? Any definition implies a determination and an expression ; how is it possible to determine that which resembles no other thing and to express something that has no other expression but its own? A definition is a general form of thinking, a form that includes a generality; the larger this generality, the more valuable the definition. Thus, how could we hope it to include the unique, which is so unlike everything else (...) that it cannot be contained in any generalization, and which, coinciding with the universal, breaks the particular/general relation? Since these two terms are not able to account for the unique, this one is not to be treated as a concept, but as an idea. Further, it is not too great an effort to recognize that the idea of the unique stems from the idea of the One. But who can define the One except by a tautology? (shrink)

The authors are focusing on the relation of migration and labour by discussing Michael Hardt and Antonio Negri’s « Empire » on the one hand, and Giorgio Agamben’s notion of Lager on the other. Migration, they argue, can be understood as a form of class struggle, in which demands for autonomy and self-determination find their spontaneous expression.

This is an exposition of what the author calls ‘non-classical epistemology’ in close relationship with the emergence and development of quantum mechanics.

Given the contemporary ambivalent standpoints toward the future of artificial intelligence, recently denoted as the phenomenon of Singularitarianism, Gregory Bateson’s core theories of ecology of mind, schismogenesis, and double bind, are hereby revisited, taken out of their respective sociological, anthropological, and psychotherapeutic contexts and recontextualized in the field of Roboethics as to a twofold aim: the proposal of a rigid ethical standpoint toward both artificial and non-artificial agents, and an explanatory analysis of the reasons bringing about such a polarized outcome (...) of contradictory views in regard to the future of robots. Firstly, the paper applies the Batesonian ecology of mind for constructing a unified roboethical framework which endorses a flat ontology embracing multiple forms of agency, borrowing elements from Floridi’s information ethics, classic virtue ethics, Felix Guattari’s ecosophy, Braidotti’s posthumanism, and the Japanese animist doctrine of Rinri. The proposed framework wishes to act as a pragmatic solution to the endless dispute regarding the nature of consciousness or the natural/artificial dichotomy and as a further argumentation against the recognition of future artificial agency as a potential existential threat. Secondly, schismogenic analysis is employed to describe the emergence of the hostile human–robot cultural contact, tracing its origins in the early scientific discourse of man–machine symbiosis up to the contemporary countermeasures against superintelligent agents. Thirdly, Bateson’s double bind theory is utilized as an analytic methodological tool of humanity’s collective agency, leading to the hypothesis of collective schizophrenic symptomatology, due to the constancy and intensity of confronting messages emitted by either proponents or opponents of artificial intelligence. The double bind’s treatment is the mirroring “therapeutic double bind,” and the article concludes in proposing the conceptual pragmatic imperative necessary for such a condition to follow: humanity’s conscience of habitualizing danger and familiarization with its possible future extinction, as the result of a progressive blurrification between natural and artificial agency, succeeded by a totally non-organic intelligent form of agency.

This paper aims to be a contribution to the recent discussion on the science-metaphysics relationship. After drawing a distinction between two aspects of the relationship, it defends the theoretical importance of the proposed distinction and argues for the interconnectedness of the aspects in question. The paper then focuses on one of those aspects: that is, the methodological strategy of some metaphysicians to appeal to scientific findings and practice in the course of discussing various pure metaphysical problems. It discusses the question (...) about the scope of science-informed metaphysics and its relation to the issue concerning the existence of an autonomous metaphysical possibility. Finally, the paper explores the reasons metaphysicians have for involving science in metaphysical discussions. (shrink)

Religion and specific religious dimensions have been hypothesized to reflect and have an effect on sense of humor, especially from a personality psychology perspective. Some empirical evidence tends to confirm this hypothesis, at least when behavioral measure but not questionnaires are used. However, sense of humor is not restricted to humor creation, but includes other components such as humor appreciation. In the present study , as hypothesized, religious fundamentalism and orthodoxy were found to be negatively related to humor appreciation in (...) general and to appreciation of incongruity-resolution and nonsense humor in particular, whereas religious historical relativism was positively related to appreciation of nonsense humor. However, religiosity was unrelated to humor appreciation and no religious dimension predicted low appreciation of sexual humor. (shrink)

Are there trans-religious, trans-cultural constants in psychological aspects of religion across different religions and cultures? An excessively culturalistic approach may overlook this possibility, putting an emphasis on the uniqueness of the religious phenomenon studied as emerging from a complex of multiple contextual factors. This article reviews empirical studies in psychology of religion in the 1990s that mainly include participants from different Christian denominations, but also from other religions: Muslims, Jews and Hindus. It appeared, at first, that several cross-cultural/religious differences can (...) be documented , but the interpretation of these differences is not simple, as other factors may interfere. Secondly it turned out that an impressive series of psychological constants also exist across different denominations, religions, and cultures. These constants include personality correlates, gender and gender orientation, positive and negative values, cognitive and affective aspects, identity formation, social attitudes and consequences.

Until recently, the powerful qualities view about properties has been effectively identified with the so-called identity theory. Yet, the difficulties that the latter faces (especially concerning the interpretation of its core claim that dispositionality and qualitativity are identical) have led some metaphysicians to propose (at least provisionally) new versions of the powerful qualities view. This paper discusses the prospects of three such versions: the compound view, the higher-order properties theory and the dual aspect account. It is argued that the compound (...) view is in fact property dualism in disguise, while the higher-order properties theory does not by itself provide a metaphysically convincing solution to Armstrong’s dilemma concerning the modal status of the relation between dispositionality and categoricality. Finally, it is argued that it is not clear whether the dual aspect account is distinct from identity theory and pure powerism. (shrink)

The Identity Theory of properties is an increasingly popular metaphysical view that aims to be a middle way between pure powerism and pure categoricalism. This paper’s goal is to highlight three major difficulties that IDT should address in order to be a plausible account of the nature of properties. First, although IDT needs a clear definition of the notion of qualitativity which is both adequate and compatible with the tenets of the theory, all the extant proposals fail to provide such (...) a definition. Second, the suggested definitions of qualitativity are characterised by a metaphysical ‘neutrality’ that threatens to trivialise the important metaphysical debate regarding the question whether properties confer by themselves dispositions on their bearers or need the ‘assistance’ of laws of nature to do that. Finally, none of the extant alternative understandings of the core identity-claim of IDT can adequately meet the objection that the claim in question is unintelligible. (shrink)

The vast majority of metaphysicians agree that powers (in contrast to categorical properties) can exist unmanifested. This paper focuses on the ontological distinction between unmanifested and manifested powers underpinning that fact and has two main aims. First, to determine the proper relata of the distinction and second, to show that an unrestricted version of dispositional monism faces serious difficulties to accommodate it. As far as the first aim is concerned, it is argued that the distinction in question, in order to (...) be free of irrelevant features, must hold between an un- manifested power-instance and the same power-instance being manifested. To the second end, the paper examines two possible candidate distinctions (actual vs. possible, be- ing-in-energeia vs. being-in-capacity). It is argued that the former fails to be a good fit for the role that the distinction under consideration should play in a dispositional monistic context. It is also argued that a specific version of the latter can ground a promising solution to the difficulty discussed in the paper. That solution, however, presupposes the inclusion of aspects of the Aristotelian metaphysical framework for powers to the dispositional monistic context. (shrink)

Previous research on religion and helping has left some questions unanswered. In the present study, participants expressed willingness to help groups of people in need, and this after having been religiously versus non-religiously stimulated. The activation of religious context increased the willingness to help, but only the homeless. Orthodox religious people tended to consider the targets responsible for their problem, an association partially mediated by the belief in a just world for other. Symbolic thinking was associated with willingness for helping, (...) an association partially mediated by the belief in ultimate justice. Results suggest a limited and conditional prosociality as a consequence of religion. (shrink)

Most metaphysicians agree that powers can exist without being manifested. The main goal of this paper is to show that adherents of an unrestricted version of Dispositional Monism cannot provide a plausible metaphysical account of the difference between a situation in which a power-instance is not manifested and a situation in which a manifestation of that power-instance actually occurs unless they undermine their own view. To this end, two kinds of manifestation-relation are introduced and it is argued that dispositional monists (...) should appeal to the former in order to offer the required account. After defending the introduction of token-level-manifestation-relations against objections to their metaphysical robustness and explanatory non-redundancy, it is finally argued that their existence is incompatible with the core tenet of an unrestricted form of Dispositional Monism because they cannot be powers.

In the present study, we examined how the religiousness of European Muslim immigrants is related to multiple collective identities , attachment to one or both cultures, and acculturation as a process realized through a variety of domains in personal and social life. Two groups were included: young Muslims born of immigration from Muslim countries and, for comparison, young non-Muslims born of immigration from other countries. In both groups, high religiousness predicted attachment to origin identity and culture; low religiousness and religious (...) doubting predicted identification with the host country and acculturation. Interestingly, the religiousness of Muslim immigrants also predicted high identification as citizen of the world, whereas the religiousness of the other immigrants was related to low European identity. Finally, some discrepancy between claiming new identities and effectively experiencing acculturation was found. Interpretations are provided on both a general level and a contextual level. (shrink)

This book examines the metaphysical issues regarding the powerful qualities view in all its various forms. The author also develops and defends his own version of the powerful qualities view, which he calls powerful categoricalism. In recent years, the powerful qualities view about the nature of properties has received considerable attention in the philosophical literature. The core tenet of the powerful qualities view is that properties are both dispositional and categorical/qualitative. Despite the increased popularity of the powerful qualities view, there (...) is no book-length presentation of the view in its distinct versions. The first part of this book analyzes the advantages and drawbacks of each version of the theory paying special attention to those difficulties that make it unstable and perhaps incomprehensible. In the second part, the author shows how a developed version of a dualist model for the origin of natural modality-according to which the specific behaviour of things in the world is the outcome of both the thin power properties have to be nomically relatable and certain nomic relations that determine properties' nomological role-can support an alternative understanding of the main tenet of the powerful qualities view. This part, in combination with the discussion of the difficulties of the other versions, not only defends the tenability of powerful categoricalism but also its superiority over the other extant versions. The Metaphysics of Powerful Qualities makes an original contribution to an ongoing debate in contemporary metaphysics. (shrink)

Most recently Smart and Thébault revived an almost forgotten debate between Katzav and Ellis on the compatibility of Hamilton’s Principle with Dispositional Essentialism. Katzav’s arguments inter alia aim to show that HP presupposes a kind of metaphysical contingency which is at odds with the basic tenets of DE, and offers explanations of a different type and direction from those given by DE. In this paper I argue that though dispositional essentialists might adequately respond to these arguments, the question about the (...) compatibility of HP with DE has not been answered yet; therefore, dispositional essentialists have not yet provided an illuminating DE-friendly metaphysical account of HP.

How can we be certain of what a physics theory is talking about and, at the same time, not have a clue what the theory is about? Yet, this seemingly nonsensical question lurks in the background since the advent of quantum physics and is intimately entangled with the cluster of issues constituting the raw material for philosophers of science striving to negotiate the so-called classical to quantum divide.The discourse of theoretical physics unfolds on two levels: the experimental and the mathematical.

It is based on the competent use of everyday language, significantly enriched with sharply defined concepts, in order to deploy necessary resources, to set up and faithfully describe an experimental procedure, and to unambiguously communicate its results.

What does it mean to be real? Could reality, taken in itself, have a sense? Or, can a reality different from and independent of any thinking possess sense? But if thinking were not of reality, would it still be able to be as such? Furthermore, is all genuine thinking in some sense unreal? The present essay addresses these issues. However, first of all, certain definitions are necessary, the most controversial being, undoubtedly, that of reality. Let us begin by trying to (...) establish the boundaries of the real, so as to be in a position to discover if there is some possibility of transcending them. (shrink)

Conducting marine mammal research can raise several important ethical issues. For example, the continuation of whaling for commercial purposes despite the international moratorium provides opportunities for scientists to obtain data and tissue samples. In 2021 we analysed 35 peer-reviewed papers reporting research based on collaborations with Icelandic whalers. Results highlighted little consideration or understanding of the legal and ethical issues associated with the deliberate killing of whales amongst those researchers, funding bodies, universities and journals involved. Ethical statements were rarely provided. (...) Those that were written were incomplete. Whilst research using whaling data may seem acceptable to some, it often becomes hard to justify when subject to scrutiny by the media and the public. Thus, there is a particular danger of reputational harm for early career researchers who may become unwittingly involved in such activities. Here we also consider the broader variety of ethical issues raised by non-lethal research (both historical and recent) on marine mammals including tagging and biopsy. We discuss instances where study animals were harmed or even killed and where the public mistook tags for harpoons. Without clear guidelines, reviewers and journal editors are put in an impossible position when considering whether to reject papers on ethical grounds. We propose that for such studies, universities, funders, journals, and permit issuers must require ethical assessments and that journals more effectively implement their existing policies on publishing ethical statements. The professional marine mammal societies need to work together to produce modern ethical guidance. Such guidance should require transparency in the provenance of data and samples while including advice on law, welfare issues, involvement of local scientists, and offshoring. Furthermore, it should require appraisal of and justification for the absolute necessity of invasive procedures. As is already the case in biomedical disciplines, ethical statements should be required in marine mammal science. (shrink)
