In my articles ‘The Substance View: A Critique’ and ‘The Substance View: A Critique,’ I raise objections to the substance view, a theory of intrinsic value and moral standing defended by a number of contemporary moral philosophers, including Robert P. George, Patrick Lee, Christopher Tollefsen, and Francis Beckwith. In part one of my critique of the substance view, I raise reductio-style objections to the substance view's conclusion that the standard human fetus has the same intrinsic value and moral (...) standing as the standard adult human being, among other human beings. In part two, I raise objections to some of the premises invoked in support of that conclusion. Here, in part three, I raise objections to Henrik Friberg-Fernros's attempt to rebut some of the aforementioned objections. (shrink)

Prominent Kantian scholars, such as Korsgaard and Waldron, claim that the very existence of juridical-political institutions is sufficient to render laws authoritative. Critics argue that this view is unpersuasive as it requires subjects to obey grossly unjust laws. Here, I identify two problems facing scholars who reject the absolutist view of political authority proffered by Korsgaard and Waldron. First, when there is reasonable disagreement regarding a law’s legitimacy the Principle of Right generates contradictory obligations as it commands both disobedience and (...) compliance. In clarifying this problem, I argue that individuals must disobey illegitimate laws where this requirement is co-extensive with the duty to leave the state of nature. However, disobedience amounts to domination when individuals are subjected to private judgments regarding the conditions of freedom. The Principle of Right cannot overcome this impasse as it does not offer reasons in favor of compliance that are distinct from those reasons legitimating the law. To address this issue, I supplement Kant’s account with Joseph Raz’s ‘service conception’ of authority to show that compliance can be rendered compatible with the Principle of Right. A second problem emerges when laws are blatantly illegitimate such that obedience cannot be justified. In these cases, the Principle of Right cannot guide legislative reform in an intuitively appealing way as it fails to address considerations of proportionality. Though this latter problem is not resolved here, identifying it helps to further clarify the relationship between Kant’s moral and political principles. (shrink)

In Liberalism's Troubled Search for Equality, Robert P. Jones asks why these concerns were dismissed by liberal philosophers and argues that this contradiction exposes a blind spot within liberal political theory.

Random-excitation granule cells are likely to overwhelm spatiotemporal sequences described as in Braitenberg et al.'s target article. A mechanism is proposed involving the Golgi cells to reinforce tidal waves against noise. The recurrent inhibition by the Golgi calls can recruit random excitations of granule cells in phase with sequences of mossy fiber input.

The field theoretic approach of the target article is simplified by setting the parameters of the dynamical field equation so that the system is near the critical point between cooperative and non-cooperative dynamics. However, embodiment of cognitive development would require a closer connection between the dynamical field interactions and the physiology of the cerebral cortex.

Lucretius believed that the gods were wholly perfect and self-sufficient, not vengeful and requiring appeasement. He believed contemplation of the gods allowed one to reach a similar state, as it clarified what was important for a successful human life. This article intends to examine how this theology affects Lucretius’s view of nonhuman-human interaction. It will reach the conclusion that Lucretian Epicureanism contains within it a deep appreciation of the value of life and so prohibits unnecessary disturbance to the lives of (...) others, including nonhuman animals.

Extinct megafaunal mammals in the Americas are often linked to seed-dispersal mutualisms with large-fruiting tree species, but large-fruiting species in Europe and Asia have received far less attention. Several species of arboreal Maloideae (apples and pears) and Prunoideae (plums and peaches) evolved large fruits starting around nine million years ago, primarily in Eurasia. As evolutionary adaptations for seed dispersal by animals, the size, high sugar content, and bright colorful visual displays of ripeness suggest that mutualism with megafaunal mammals facilitated the (...) evolutionary change. There has been little discussion as to which animals were likely candidate(s) on the late Miocene landscape of Eurasia. We argue that several possible dispersers could have consumed the large fruits, with endozoochoric dispersal usually relying on guilds of species. During the Pleistocene and Holocene, the dispersal guild likely included ursids, equids, and elephantids. During the late Miocene, large primates were likely also among the members of this guild, and the potential of a long-held mutualism between the ape and apple clades merits further discussion. If primates were a driving factor in the evolution of this large-fruit seed-dispersal system, it would represent an example of seed-dispersal-based mutualism with hominids millions of years prior to crop domestication or the development of cultural practices, such as farming.

J. L. Schellenberg claims that the weakness of evidence for God’s existence is not merely a sign that God is hidden, “it is a revelation that God does not exist.” In Divine Hiddenness : New Essays, Michael J. Murray provides a “soul-making” defense of God’s hiddenness, arguing that if God were not hidden, then some of us would lose what many theists deem a good thing: the ability to develop morally significant characters. In this paper, I argue that Murray’s soul-making (...) defense not only fails to defend God’s hiddenness, it produces an argument for the nonexistence of God. (shrink)

Profoundly important ethical and political controversies turn on the question of whether biological life is an essential aspect of a human person, or only an extrinsic instrument. Lee and George argue that human beings are physical, animal organisms - albeit essentially rational and free - and examine the implications of this understanding of human beings for some of the most controversial issues in contemporary ethics and politics. The authors argue that human beings are animal organisms and that their personal identity (...) across time consists in the persistence of the animal organisms they are; they also argue that human beings are essentially rational and free and that there is a radical difference between human beings and other animals; criticize hedonism and hedonistic drug-taking; present detailed defenses of the prolife positions on abortion and euthanasia; and defend the traditional moral position on marriage and sexual acts.

We argue that all human beings have a special type of dignity which is the basis for (1) the obligation all of us have not to kill them, (2) the obligation to take their well-being into account when we act, and (3) even the obligation to treat them as we would have them treat us, and indeed, that all human beings are equal in fundamental dignity. We give reasons to oppose the position that only some human beings, because of their (...) possession of certain characteristics in addition to their humanity (for example, an immediately exercisable capacity for self-consciousness, or for rational deliberation), have full moral worth. What distinguishes human beings from other animals, what makes human beings persons rather than things, is their rational nature, and human beings are rational creatures by virtue of possessing natural capacities for conceptual thought, deliberation, and free choice, that is, the natural capacity to shape their own lives.

The traditional approach to the abortion debate revolves around numerous issues, such as whether the fetus is a person, whether the fetus has rights, and more. Don Marquis suggests that this traditional approach leads to a standoff and that the abortion debate “requires a different strategy.” Hence his “future of value” strategy, which is summarized as follows: (1) A normal fetus has a future of value. (2) Depriving a normal fetus of a future of value imposes a misfortune on it. (...) (3) Imposing a misfortune on a normal fetus is prima facie wrong. (4) Therefore, depriving a normal fetus of a future of value is prima facie wrong. (5) Killing a normal fetus deprives it of a future of value. (6) Therefore, killing a normal fetus is prima facie wrong. In this paper, I argue that Marquis’s strategy is not different since it involves the concept of person—a concept deeply rooted in the traditional approach. Specifically, I argue that futures are valuable insofar as they are not only dominated by goods of consciousness, but are experienced by psychologically continuous persons. Moreover, I argue that his strategy is not sound since premise (1) is false. Specifically, I argue that a normal fetus, at least during the first trimester, is not a person. Thus, during that stage of development it is not capable of experiencing its future as a psychologically continuous person and, hence, it does not have a future of value. (shrink)

We review the status of bouncing cosmologies as alternatives to cosmological inflation for providing a description of the very early universe, and a source for the cosmological perturbations which are observed today. We focus on the motivation for considering bouncing cosmologies, the origin of fluctuations in these models, and the challenges which various implementations face.

In this paper, I attempt to demonstrate that environmental virtue ethics (EVE) fails to provide sufficient justification for the hunting of nonhuman animals. In order to do this, I examine an EVE justification for the hunting of nonhuman animals and argue that it gives rise to the following dilemma: either EVE justifies the hunting of both human and nonhuman animals, or it justifies the hunting of neither. I then submit that the first lemma ought to be rejected as absurd and, (...) thus, that the second lemma ought to be embraced. (shrink)

In the contemporary debate on moral status, it is not uncommon to find philosophers who embrace the the Principle of Full Moral Status, according to which the degree to which an entity E possesses moral status is proportional to the degree to which E possesses morally relevant properties until a threshold degree of morally relevant properties possession is reached, whereupon the degree to which E possesses morally relevant properties may continue to increase, but the degree to which E possesses moral (...) status remains the same. One philosopher who has contributed significantly to the contemporary debate on moral status and embraces the Principle of Full Moral Status is Mary Anne Warren. Warren holds not only that it is possible for some entities to possess full moral status, but that some entities actually do, e.g., normal adult human beings. I argue that two of Warren’s primary arguments for the Principle of Full Moral Status—the Argument from Pragmatism and the Argument from Explanatory Power—are significantly flawed. (shrink)

In various places we have defended the position that a new human organism, that is, an individual member of the human species, comes to be at fertilization, the union of the spermatozoon and the oocyte. This individual organism, during the ordinary course of embryological development, remains the same individual and does not undergo any further substantial change, unless monozygotic twinning, or some form of chimerism occurs. Recently, in this Journal Jason Morris has challenged our position, claiming that recent findings in (...) reproductive and stem cell biology have falsified our view. He objects to our claim that a discernible substantial change occurs at conception, giving rise to the existence of a new individual of the human species. In addition, he objects to our claim that the embryo is an individual, a unified whole that persists through various changes, and thus something other than a mere aggregate of cells. Morris raises a number of objections to these claims. However, we will show that his arguments overlook key data and confuse biological, metaphysical, and ethical questions. As a result, his attempts to rebut our arguments fail. (shrink)

This book defends the conjugal view of marriage. Patrick Lee and Robert P. George argue that marriage is a distinctive type of community: the union of a man and a woman who have committed to sharing their lives on every level of their beings (bodily, emotionally, and spiritually) in the kind of union that would be fulfilled by conceiving and rearing children together. The comprehensive nature of this union, and its intrinsic orientation to procreation as its natural fulfillment, (...) distinguishes marriage from other types of community and provides the basis for the norms of marital exclusivity and permanence. Lee and George detail how the basic moral norms regarding sexual acts follow from the ethical requirement to respect the good of marriage and explain how the law should treat marriage, given its conjugal nature, examining both the same-sex-marriage issue and civil divorce.

Abstract. We argue that all human beings have a special type of dignity which is the basis for (1) the obligation all of us have not to kill them, (2) the obligation to take their well-being into account when we act, and (3) even the obligation to treat them as we would have them treat us, and indeed, that all human beings are equal in fundamental dignity.

What distinguishes human beings from other animals, what makes human beings persons rather than things, is their rational nature, and human beings are rational creatures by virtue of possessing natural capacities for conceptual thought, deliberation, and free choice, that is, the natural capacity to shape their own lives.

Integrity is a central topic in business ethics, and in the world of business it is quite possibly the most commonly cited morally desirable trait. But integrity is conceived in widely differing ways, and as often as it is discussed in the literature and given a central place in corporate ethics statements, the notion is used so variously that its value in guiding everyday conduct may be more limited than is generally supposed. Two central questions for this paper are what (...) work the notion does and whether it does any ethical work that is not done better by other concepts. In pursuing these questions the paper explores the most plausible range of understandings of integrity found in recent literature, considers in what sense it is a virtue, and proposes a strategy of clarification and interpretation that can facilitate both ethical reflection and the guidance of moral conduct in business.

‘The problem with simulations is that they are doomed to succeed.’ So runs a common criticism of simulations—that they can be used to ‘prove’ anything and are thus of little or no scientific value. While this particular objection represents a minority view, especially among those who work with simulations in a scientific context, it raises a difficult question: what standards should we use to differentiate a simulation that fails from one that succeeds? In this paper we build on a structural (...) analysis of simulation developed in previous work to provide an evaluative account of the variety of ways in which simulations do fail. We expand the structural analysis in terms of the relationship between a simulation and its real-world target emphasizing the important role of aspects intended to correspond and also those specifically intended not to correspond to reality. The result is an outline both of the ways in which simulations can fail and the scientific importance of those various forms of failure. (shrink)

While we agree that the frame problem, as initially stated by McCarthy and Hayes (1969), is a problem that arises because of the use of representations, we do not accept the anti-representationalist position that the way around the problem is to eliminate representations. We believe that internal representations of the external world are a necessary, perhaps even a defining feature, of higher cognition. We explore the notion of dynamically created context-dependent representations that emerge from a continual interaction between working memory, (...) external input, and long-term memory. We claim that only this kind of representation, necessary for higher cognitive abilities such as counterfactualization, will allow the combinatorial explosion inherent in the frame problem to be avoided.

We apply spatialized game theory and multi-agent computational modeling as philosophical tools: (1) for assessing the primary social psychological hypothesis regarding prejudice reduction, and (2) for pursuing a deeper understanding of the basic mechanisms of prejudice reduction.

The ovarian tumor (otu) gene behaves as if it encodes a product (OGP) which is required during several early steps in the transformation of oogonia into functional oocytes. The ovarian phenotypes produced by various EMS‐induced mutations can be explained as graded responses by individual mutant germ cells to the different levels of functionally active OGP they themselves synthesize. In addition, genetic evidence suggests that otu also encodes a second product that is utilized late in oogenesis. Molecular studies of the otugene (...) demonstrate that it does transcribe at least two ovaryspecific RNAs. The possible function of the otu product in the cellular divisions that give rise to the oocyte and its sister nurse cells is discussed. (shrink)

Coherence and correspondence are classical contenders as theories of truth. In this paper we examine them instead as interacting factors in the dynamics of belief across epistemic networks. We construct an agent-based model of network contact in which agents are characterized not in terms of single beliefs but in terms of internal belief suites. Individuals update elements of their belief suites on input from other agents in order both to maximize internal belief coherence and to incorporate ‘trickled in’ elements of (...) truth as correspondence. Results, though often intuitive, prove more complex than in simpler models (Hegselmann & Krause 2002, 2006; Grim, Singer, Reade & Fisher 2015). The optimistic finding is that pressures toward internal coherence can exploit and expand on small elements of truth as correspondence is introduced into epistemic networks. Less optimistic results show that pressures for coherence can also work directly against the incorporation of truth, particularly when coherence is established first and new data is introduced later.
