The proof of the Second Incompleteness Theorem consists essentially of proving the uniqueness and explicit definability of the sentence asserting its own unprovability. This turns out to be a rather general phenomenon: Every instance of self-reference describable in the modal logic of the standard proof predicate obeys a similar uniqueness and explicit definability law. The efficient determination of the explicit definitions of formulae satisfying a given instance of self-reference reduces to a simple algebraic problem-that of solving the corresponding fixed-point equation (...) in the modal logic. We survey techniques for the efficient calculation of such fixed-points. (shrink)

In a recent paper, Montagna proved the undecidability of the first-order theory of diagonalisable algebras. This result is here refined — the set of finitely refutable sentences is shown effectively inseparable from the set of theorems. The proof is quite simple.

Over 50% of the world population will develop a psychiatric disorder in their lifetime. 1 In the realm of psychiatric treatment, two primary modalities have been established: pharmacotherapy and psychotherapy. Yet, pharmacological interventions often take precedence as the initial treatment choice despite their comparable outcomes, severe side effects and disputed evidence of their efficacy. This preference for medication foregrounds a vital re-examination of what it means to be invasive in medical treatments, namely in psychiatric care. De Marco _et al_ challenge (...) the standard account of invasiveness, presenting considerations that transcend the traditional criteria of physical intrusion. 2 Through case studies centred on treatments for schizophrenia and depression, we aim to (1) reinforce De Marco _et al_’s challenge to the standard account of invasiveness and (2) extend the dialogue to the moral imperative of redefining mental invasiveness. Our aims are to broaden the definition of mental invasiveness, aligning... (shrink)

This book argues that the moral quality of an act comes from the agent's inner states. By arguing for the indispensable relevance of intention in the moral evaluation of acts, the book moves against a mainstream, 'objective' approach in normative ethics. It is commonly held that the intentions, knowledge, and volition of agents are irrelevant to the moral permissibility of their acts. This book stresses that the capacities of agency, rather than simply the label 'agent', must be engaged during an (...) act if its moral evaluation is to be coherent. The author begins with an ontological argument that an act is a motion or a causing of change in something else. He argues that the source of an act's moral meaning is in the agent: specifically, what the agent, if aware of relevant facts around her, aims to accomplish. He then moves to a series of critical chapters that consider arguments for mainstream approaches to act evaluation, including Thomson's dismissal of the agent knowledge and volition requirements, Scanlon's arguments for a derivative relevance of intentions to permissibility, Frowe's "causal roles" of agents in the moral evaluation of acts, and Bennett's explicit defense of the objective approach. The book concludes by offering the author's preferred replacement for the objective approach, an Aristotelian-Thomist view of acts. Acts, Intentions, and Moral Evaluation will be of interest to scholars and advanced students working in ethics, just war theory, the ethics of self-defense, and philosophy of action. (shrink)

This chapter offers an interpretation of Gottfried Wilhelm Leibniz’s idealism. Despite Leibniz’s frequent claim that the universe ultimately boils down to monads, he also sometimes appears to say that the world’s fundamental furniture includes extended, corporeal substances. Here, I examine Leibniz’s views about the relationship between monads and the material world, especially in connection with material bodies and corporeal substances.

It is an open question when procreation is justified. Antinatalists argue that bringing a new individual into the world is morally wrong, whereas pronatalists say that creating new life is morally good. In between these positions lie attempts to provide conditions for when taking an anti or pronatal stance is appropriate. This paper is concerned with developing one of these attempts, which can be called qualified pronatalism. Qualified pronatalism typically claims that while procreation can be morally permissible, there are constraints (...) on when it is justified. These constraints often concern whether an individual is motivated to procreate for the right reasons. For instance, if someone is not sufficiently concerned with the child’s future welfare, the qualified pronatalist will say that procreation is not justified. Moreover, David Wasserman says that this concern forms a role-based duty. That is, prospective parents have special duties to be concerned for the child’s future welfare by virtue of the role they occupy. In this paper, I argue that a proper examination of a prospective parent’s role-based duties entails that more is needed to justify procreation. Bringing a new person into the world leaves fewer resources for people who already need them, and the current size of the human population is unsustainable from a planetary point of view. Therefore, even if there is nothing wrong with procreation per se, the external condition of overpopulation, and its ensuing public health issues, plausibly gives rise to a role-based duty that prospective parents must account for when deciding whether to procreate.

The farms in the LEGO Farm theme are immaculate. They feature sparkling clean tractors, pristine fences, and the complete absence of dirt. Whether it is on purpose, or a limitation based on the number of pieces that can be placed inside a box, LEGO Farm presents an agricultural utopia. The farms are smaller, less dependent on toxic inputs, and friendlier to animals than real‐life commercial farms. LEGO Farm often features animals that are clean and well fed. Some animals even appear (...) to be smiling, and that's appropriate considering that they are viewed as living creatures rather than commodities. With LEGO, kids and adults can imagine farms as they would ideally make them. The beauty of LEGO is that anyone can be a Master Builder, building their own MOCs. As a Master Farmer the possibilities for representing environmentally friendly agriculture are endless. (shrink)

The idea that human beings have a distinct moral worth—a moral significance over and above any moral worth, such as that may be, possessed by other animals—has a long history and has traditionally been taken for granted by philosophers and theologians. However, in a variety of quarters in recent philosophy, this idea has come into disrepute, seeming to indicate a mere prejudice in favour of our own species. For example, Peter Singer has argued that such a position is mere speciesism, (...) a prejudice of a kind with racism and sexism in that it involves making moral distinctions between our own and other species that cannot be morally justified. What on such views is needed to justify any such distinction is a difference in terms of the morally relevant properties possessed by our own species as compared with other species. I will call this view the moral property view. Insofar as other species share with us morally relevant properties, for example the capacity to suffer cognitive ability and so on, it is mere prejudice not to accept moral requirements with respect to them as we do with respect to our own species. While on the surface such a view may seem morally enlightened, it indicates what will seem to many problematic moral judgments with respect to severely disabled human beings. In this paper, I will respond to these concerns by suggesting a different basis for the idea of human moral distinctiveness, one that draws on recent work by Wittgensteinian moral philosophers and which denies what I called above the property view. According to this view, while our shared life with other animals involves the recognition of their moral significance, our shared life with other human beings involves recognising that human beings as human beings have a distinctive moral value.

Politics pervades every aspect of our lives as human beings. As Aristotle said, we are "political animals.

The essays in this collection examine the influence of Gaita's ethical thought in a broad sense, beyond academic philosophy, especially within Australian society and culture where it has been most significant. Through his various works, including his acclaimed biography, Romulus: My Father, Gaita's ethical thought has had a considerable impact on the intellectual and cultural life of Australia.

Leading social innovation is challenging. Creating enduring social innovation requires navigating the tension of simultaneously engaging top-down and shared leadership. We outline the crux of the challenge and provide key takeaways and practical advice for the tandem deployment of top-down and shared leadership for social innovation success.

How can we talk meaningfully about the past if it does not exist to be talked about? What gives time its direction? Is time travel possible? This defence of presentism - the view that only the present exists - makes an original contribution to a fast growing and exciting debate.

Free in Deed provides an imaginative and succinct introduction to Lutheran ethics, which author Craig L. Nessan contends is, finally, neighbor ethics. The gospel of Jesus Christ sets us free to serve the well-being of our neighbors and all of creation. This Lutheran framework provides a distinctive approach for navigating social issues in tumultuous times."--back cover.

A framework for pragmatic analysis is proposed which treats discourse as a game, with context as a scoreboard organized around the questions under discussion by the interlocutors. The framework is intended to be coordinated with a dynamic compositional semantics. Accordingly, the context of utterance is modeled as a tuple of different types of information, and the questions therein — modeled, as is usual in formal semantics, as alternative sets of propositions — constrain the felicitous flow of discourse. A requirement of (...) Relevance is satisfied by an utterance (whether an assertion, a question or a suggestion) iff it addresses the question under discussion. Finally, it is argued that the prosodic focus of an utterance canonically serves to reflect the question under discussion (at least in English), placing additional constraints on felicity in context.

In 21st century America, personhood is under daily assault, sometimes with dire consequences. Scientist, ethicist, and ordained minister Craig C. Malbon encourages the reader to consider such assaults on personhood endured by victims of abortion, ageism, Alzheimer's disease, drug addiction, mental and physical disabilities, gender, gender orientation, racism, sexual preference, identity politics, and our will-to-power over the "other." In exploring personhood status, Malbon poses difficult questions for us. Is personhood assigned as all-or-nothing, or is it a sliding scale based (...) upon criteria arbitrarily aimed at our vulnerabilities? Does the voiceless embryo and fetus have advocates who can speak to the moral question of abortion? Is the personhood of an economically insecure pregnant woman degraded to the point where lack of access to early termination of pregnancy results in "coercive childbearing?" Does being a member of the LGBTQI+ community target one for assaults on personhood, to the extreme of being killed? In delving into the biology and psychology of assaults of "self" upon the "other," Malbon sees powerful linkages of everyday assaults on personhood to darker, profound "original sins" that are foundational to the rise of the American empire, i.e., assaults on the indigenous Native Americans and assaults derivative to the institution of slavery upon Africans, African Americans, and their descendants.

Racism in Psychology examines the history of racism in psychological theory, practice and institutions. The book offers critical reviews by scholars and practising therapists from the US, Africa, Asia, Australia and Europe on racism on the couch and in the wider socio-historical context. The authors present a mixed experience of the success of efforts to counter racism in theory, institutions and organizations and differing views on the possibility of institutional change. Chapters discuss the experience of therapists, anti-Semitism, inter-sectionality and how (...) psychological praxis is part of a colonialist project. The book will appeal to practising psychologists and counsellors, socially minded psychotherapists, social workers, sociologists and students of psychology, social studies and race relations.

In line with her hopes, Philosophical Psychology outlines a vision that seeks to do justice to the complexity of the human person.

The counterfactual mental state of negligent criminal activity invites skepticism from those who see mental states as essential to responsibility. Here, I offer a revision of the mental state of criminal negligence, one where the mental state at issue is actual and not merely counterfactual. This revision dissolves the worry raised by the skeptic and helps to explain negligence’s comparatively reduced culpability.

Given his view that the modern world is ‘radically evil’, Adorno is an unlikely contributor to business ethics. Despite this, we argue that his work has a number of provocative implications for the field that warrant wider attention. Adorno regards our social world as damaged, unfree, and false and we draw on this critique to outline why the achievement of good work is so rare in contemporary society, focusing in particular on the ethical demands of roles and the ideological nature (...) of management’s self-understanding. Nevertheless, we show that Adorno’s comments on activities such as art and philosophy mean that it is possible to draw on his work in a way that contributes constructively to the conversation about good and meaningful work within business ethics.
