One of the most famous, and most derided, arguments against the morality of abortion is the argument from potential, which maintains that the fetus' potential to become a person and enjoy the valuable life common to persons, entails that its destruction is prima facie morally impermissible. In this paper, I will revisit and offer a defense of the argument from potential.

One argument used by detractors of human embryonic stem cell research (hESCR) invokes Kant's formula of humanity, which proscribes treating persons solely as a means to an end, rather than as ends in themselves. According to Fuat S. Oduncu, for example, adhering to this imperative entails that human embryos should not be disaggregated to obtain pluripotent stem cells for hESCR. Given that human embryos are Kantian persons from the time of their conception, killing them to obtain their cells for research (...) fails to treat them as ends in themselves. (shrink)

In recent years, there has been a marked increase in the use of imaginative play in child psychotherapy, yet the theoretical conceptualization of the meaning of play is lacking behind its application in practice. In search of a deeper understanding of the phenomenon of imaginative play, the author turns to Merleau-Ponty's ontology and to his phenomenology of structure, of the lived body, of perception, and of expression. In light of his work, play is an embodied mode of being in the (...) world and a body-world phenomenon. Imaginative play in particular exemplifies the human order in that it enables the child to create and re-create his own meanings within his play world. In a therapeutic context, the evocation of play imagery and the expressive shaping and reshaping of play meanings lead to surprising insights and new discoveries relevant to the child's life-world. A central therapeutic value of imaginative play lies in its promise for facilitating change and healing. A clinical case illustration of a young boy is provided, and the meaning of his imaginative play is exemplified in light of Merleau-Ponty's thought. Some implications are drawn for the theory of play in child psychotherapy. (shrink)

In his original metabletic research on the nature of neurosis. Van den Berg revealed how, towards the 19th century, the increasingly complex and dividing nature of Western society led to the emergence of neurosis as a form of divided existence. By the mid 20th century, the manifestations of neurosis itself changed from a crystalized disorder to vague neurotic disturbances which Van den Berg related to the societal disorder, incoherence and instability which followed the second world war. He identified a series (...) of neuroticizing factors at the time including the ambivalence of society, the increased mobility, a changed sense of time, the disappearance of small groups, the weakening of family ties and the fear of death. In our postmodern world today, the nature of neurosis has changed once again and awaits a new metabletic investigation to reveal its nature and its particular manifestations. (shrink)

In 2008, many states sought to pass Human Life Amendments, which would extend the definition of personhood to encompass newly fertilized eggs. If such an amendment were to pass, Roe v. Wade, as currently defended by the Supreme Court, may be repealed. Consequently, it is necessary to defend the right to an abortion in a manner that succeeds even if a Human Life Amendment successfully passes. J.J. Thomson's argument in “A Defense of Abortion” successfully achieves this. Her argument is especially (...) strong when one considers that her central thesis—that one person's right to life does not entail the right to use another's person's body for continued sustenance—is pervasive in legal policies in the U.S.A.

This paper extends earlier work by its authors on formal aspects of the processes of contracting a theory to eliminate a proposition and revising a theory to introduce a proposition. In the course of the earlier work, Gardenfors developed general postulates of a more or less equational nature for such processes, whilst Alchourron and Makinson studied the particular case of contraction functions that are maximal, in the sense of yielding a maximal subset of the theory (or alternatively, of one of (...) its axiomatic bases), that fails to imply the proposition being eliminated. In the present paper, the authors study a broader class, including contraction functions that may be less than maximal. Specifically, they investigate "partial meet contraction functions", which are defined to yield the intersection of some nonempty family of maximal subsets of the theory that fail to imply the proposition being eliminated. Basic properties of these functions are established: it is shown in particular that they satisfy the Gardenfors postulates, and moreover that they are sufficiently general to provide a representation theorem for those postulates. Some special classes of partial meet contraction functions, notably those that are "relational" and "transitively relational", are studied in detail, and their connections with certain "supplementary postulates" of Gardenfors investigated, with a further representation theorem established.

One of the world's most renowned theoretical physicists, Carlo Rovelli has entranced millions of readers with his singular perspective on the cosmos. In Helgoland, Rovelli examines the enduring enigma of quantum theory. The quantum world Rovelli describes is as beautiful as it is unnerving. Helgoland is a treeless island in the North Sea where the 21-year-old Werner Heisenberg first developed quantum theory, setting off a century of scientific revolution. Full of alarming ideas (ghost waves, distant objects that seem to be (...) magically connected, cats that appear both dead and alive), quantum physics has led to countless discoveries and technological advancements. Today our understanding of the world is based on this theory, yet it is still profoundly mysterious. As scientists and philosophers continue to fiercly debate the theory's meaning, Rovelli argues that its most unsettling contradictions can be explained by seeing the world as fundamentally made of relationships, not substances. We and everything around us exist only in our interactions with one another. This bold idea suggests new directions for understanding the structure of reality and even the nature of consciousness. Rovelli makes learning about quantum mechanics an almost psychedelic experience. Shifting our perspective once again, he takes us on a riveting journey through the universe so we can better understand our place in it. (shrink)

This anthology takes a broad approach to ethics, incorporating traditional topics and texts while bringing in voices and themes that are too often excluded. A substantial section on ethical theory is provided, as are readings on topics such as oppression, sex, identity, the environment, life and death, war and terror, and caring for others. Accessible introductions and discussion questions are included throughout to contextualize material for the student reader without playing favorites among the positions at issue.

Minding Time: A Philosophical and Theoretical Approach to the Psychology of Time offers an innovative philosophical account of the most fundamental kinds of time representation.

In this article, Carlos Pereda introduces the concept of “colonial reason” and explores how philosophical practices and modes of thought are entwined with colonial political structures of exploitation, exclusion, and oppression. Pereda argues that philosophy in Latin America risks perpetuating and reinforcing the colonial gesture, either by turning to the European centers of thought (thus pursuing debates that always take place elsewhere) or by isolating itself and idealising the “own.” According to Pereda, both approaches fail to dismantle colonial violence (...) within philosophy. In his alternative approach, Pereda outlines principles and methodological criteria for the decolonisation of reason and philosophy. He emphasises the importance of methodological prudence that discerns between innocent, paralysing, and strategic uses of identity expressions and advocates for modes of reading and argumentation that conceive philosophy as an inclusive and ongoing dialogue. In Pereda’s terminology, this entails fostering “permeable reason” that manifests itself through “nomadic thinking,” a form of thinking that is capable of questioning itself and being questioned.

Many of the computing systems programmed using Machine Learning are opaque: it is difficult to know why they do what they do or how they work. Explainable Artificial Intelligence aims to develop analytic techniques that render opaque computing systems transparent, but lacks a normative framework with which to evaluate these techniques’ explanatory successes. The aim of the present discussion is to develop such a framework, paying particular attention to different stakeholders’ distinct explanatory requirements. Building on an analysis of “opacity” from (...) philosophy of science, this framework is modeled after accounts of explanation in cognitive science. The framework distinguishes between the explanation-seeking questions that are likely to be asked by different stakeholders, and specifies the general ways in which these questions should be answered so as to allow these stakeholders to perform their roles in the Machine Learning ecosystem. By applying the normative framework to recently developed techniques such as input heatmapping, feature-detector visualization, and diagnostic classification, it is possible to determine whether and to what extent techniques from Explainable Artificial Intelligence can be used to render opaque computing systems transparent and, thus, whether they can be used to solve the Black Box Problem.

In their paper 'After-birth abortion: why should the baby live?' Alberto Giubilini and Francesca Minerva argue that because there are no significant differences between a fetus and a neonate, in that neither possess sufficiently robust mental traits to qualify as persons, a neonate may be justifiably killed for any reason that also justifies abortion. To further emphasise their view that a newly born infant is more on a par with a fetus rather than a more developed baby, Giubilini and Minerva (...) elect to call this 'after-birth abortion' rather than infanticide. In this paper, I argue that their thesis is incorrect, and that the moral permissibility of abortion does not entail the moral permissibility of 'after-birth' abortion. (shrink)

In this paper, I appeal to two aspects of Immanuel Kant’s philosophy – his metaphysics and ethics – in defense of abortion rights. Many Kantian pro-life philosophers argue that Kant’s second principle formulation of the categorical imperative, which proscribes treating persons as mere means, applies to human embryos and fetuses. Kant is clear, however, that he means his imperatives to apply to persons, individuals of a rational nature. It is important to determine, therefore, whether there is anything in Kant’s philosophy (...) that permits regarding embryos and fetuses as persons, since they lack the capacity for sentience (at least until mid-gestation), let alone rational thought. In the first part of the paper, I will illustrate why there are difficulties maintaining, from a Kantian perspective, that conception marks the genesis of a new person. Even granting that embryos and fetuses are persons, however, this alone would not entail the moral impermissibility of abortion rights, mainly because prohibiting abortion, and compelling women to gestate, violates the formula of humanity against them. Developing this thesis encompasses the second part of my essay. Finally, although I argue that Kant’s philosophy lends strong support to abortion rights, this does not thereby entail that it allows for the complete dehumanization of the human fetus. By appealing to the writings of Kantian scholar Allen Wood, I will argue that a fetus’ status as a potential person does render it worthy of some degree of respect and moral value. (shrink)

The received view of dynamical explanation is that dynamical cognitive science seeks to provide covering law explanations of cognitive phenomena. By analyzing three prominent examples of dynamicist research, I show that the received view is misleading: some dynamical explanations are mechanistic explanations, and in this way resemble computational and connectionist explanations. Interestingly, these dynamical explanations invoke the mathematical framework of dynamical systems theory to describe mechanisms far more complex and distributed than the ones typically considered by philosophers. Therefore, contemporary dynamicist (...) research reveals the need for a more sophisticated account of mechanistic explanation. (shrink)

Is it possible to know anything about life we have not yet encountered? We know of only one example of life: our own. Given this, many scientists are inclined to doubt that any principles of Earth’s biology will generalize to other worlds in which life might exist. Let’s call this the “N = 1 problem.” By comparison, we expect the principles of geometry, mechanics, and chemistry would generalize. Interestingly, each of these has predictable consequences when applied to biology. The surface-to-volume (...) property of geometry, for example, limits the size of unassisted cells in a given medium. This effect is real, precise, universal, and predictive. Furthermore, there are basic problems all life must solve if it is to persist, such as resistance to radiation, faithful inheritance, and energy regulation. If these universal problems have a limited set of possible solutions, some common outcomes must consistently emerge. In this chapter, I discuss the N = 1 problem, its implications, and my response (Mariscal 2014). I hold that our current knowledge of biology can justify believing certain generalizations as holding for life anywhere. Life on Earth may be our only example of life, but this is only a reason to be cautious in our approach to life in the universe, not a reason to give up altogether. In my account, a candidate biological generalization is assessed by the assumptions it makes. A claim is accepted only if its justification includes principles of evolution, but no contingent facts of life on Earth. (shrink)

Models developed using machine learning are increasingly prevalent in scientific research. At the same time, these models are notoriously opaque. Explainable AI aims to mitigate the impact of opacity by rendering opaque models transparent. More than being just the solution to a problem, however, Explainable AI can also play an invaluable role in scientific exploration. This paper describes how post-hoc analytic techniques from Explainable AI can be used to refine target phenomena in medical science, to identify starting points for future (...) investigations of causal relationships, and to generate possible explanations of target phenomena in cognitive science. In this way, this paper describes how Explainable AI—over and above machine learning itself—contributes to the efficiency and scope of data-driven scientific research. (shrink)

In a context of pervasive digitalization of the social world, both before and during the COVID-19 pandemic, the field of education has undergone major changes with the development of digital practices and settings. However, the physical presence of the subjects and the body remain something primordial and irreplaceable in traditional educational processes. Thus, it is often assumed that virtuality is opposed to the corporeal reality of the subjects involved in teaching, learning and studying. In this paper we aim to critically (...) challenge this assumption by addressing the phenomenon of virtuality in a more original sense: as a fundamental dimension of corporeality itself. Drawing on Merleau-Ponty’s phenomenological insights, we argue that the experience of the virtual is inherently embodied and fully real. We understand corporeality and virtuality as entangled and multidimensional phenomena. At the same time, this leads us to rethink the digital as only one possible medium in which virtuality can appear as inherent to embodied experience. We develop our phenomenological approach in three instances. First, we question and bracket two common assumptions about corporeality. From our critical perspective, assumptions about a disembodied digitality and a devirtualized corporeality represent extremes within which educational discourses currently move. Second, we address the inherent virtuality of embodied experience. We outline the heuristic concept of the virtual body to describe corporeality and virtuality as entangled and multidimensional phenomena that encompass extension, intercorporeality and intermediality. Finally, we make some remarks on the relationships of corporeality and virtuality considering the challenges of digital education. (shrink)

Civil Dialogue on Abortion provides a cutting-edge discussion between two philosophy scholars on each side of the abortion debate. Bertha Alvarez Manninen argues for her pro-choice view, but also urges respect for the life of the fetus, while Jack Mulder argues for his pro-life view, but recognizes that for the pro-life movement to be consistent, it must urge society to care more for the vulnerable. Coming together to discuss their views, but also to seek common ground, the two authors (...) show how their differing positions nevertheless rest upon some common convictions. The book helps to provide a way forward for a divide that has only seemed to widen the aisle of public discourse in recent years. This engaging book will prove essential reading for students across multiple disciplines, including applied ethics, medical ethics, and bioethics, but will also be of interest to students of religious studies and women's studies.

In this paper, we present one of the main starting points of naturalism in ethics: Geach’s challenge against non-cognitivism. We try to find an answer to Geach’s challenge in the notion of family resemblance applied to ethics. In doing so we recover a not much-discussed influence of Moore on Wittgenstein’s conception of family resemblance, which leads us to define Wittgenstein as non-non-cognitivist in ethics. -/- Pre print (some changes in the published edition).

In this paper I offer a defence of a Russellian analysis of the referential uses of incomplete (mis)descriptions, in a contextual setting. With regard to the debate between a unificationist and an ambiguity approach to the formal treatment of definite descriptions (introduction), I will support the former against the latter. In 1. I explain what I mean by "essentially" incomplete descriptions: incomplete descriptions are context dependent descriptions. In 2. I examine one of the best versions of the unificationist “explicit” approach (...) given by Buchanan and Ostertag. I then show that this proposal seems unable to treat the normal uses of misdescriptions. I then accept the challenge of treating misdescriptions as a key to solving the problem of context dependent descriptions. In 3. I briefly discuss Michael Devitt’s and Joseph Almog’s treatments of referential descriptions, showing that they find it difficult to explain misdescriptions. In 4. I suggest an alternative approach to DD as contextuals, under a normative epistemic stance. Definite descriptions express (i) what a speaker should have in mind in using certain words in a certain context and (ii) what a normal speaker is justified in saying in a context, given a common basic knowledge of the lexicon. In 5. I define a procedure running on contextual parameters (partiality, perspective and approximation) as a means of representing the role of pragmatics as a filter for semantic interpretation. In 6. I defend my procedural approach against possible objections concerning the problem of the boundaries between semantics and pragmatics, relying on the distinction between semantics and theory of meaning.

This paper is concerned with formal aspects of the logic of theory change, and in particular with the process of shrinking or contracting a theory to eliminate a proposition. It continues work in the area by the authors and Peter Gärdenfors. The paper defines a notion of safe contraction of a set of propositions, shows that it satisfies the Gärdenfors postulates for contraction and thus can be represented as a partial meet contraction, and studies its properties both in general and (...) under various natural constraints.

Bayesian reverse-engineering is a research strategy for developing three-level explanations of behavior and cognition. Starting from a computational-level analysis of behavior and cognition as optimal probabilistic inference, Bayesian reverse-engineers apply numerous tweaks and heuristics to formulate testable hypotheses at the algorithmic and implementational levels. In so doing, they exploit recent technological advances in Bayesian artificial intelligence, machine learning, and statistics, but also consider established principles from cognitive psychology and neuroscience. Although these tweaks and heuristics are highly pragmatic in character and (...) are often deployed unsystematically, Bayesian reverse-engineering avoids several important worries that have been raised about the explanatory credentials of Bayesian cognitive science: the worry that the lower levels of analysis are being ignored altogether; the challenge that the mathematical models being developed are unfalsifiable; and the charge that the terms ‘optimal’ and ‘rational’ have lost their customary normative force. But while Bayesian reverse-engineering is therefore a viable and productive research strategy, it is also no fool-proof recipe for explanatory success. (shrink)
