A New Taxonomy Of Altruism In Terms Of Prosocial Behaviors, Kristin Kaiser

Dialogue & Nexus

The definition of altruism has been studied, explained, and even confused by many scholars in various fields. The term itself has been inappropriately used to describe prosocial behaviors that do not fall within the definition of altruism. An evaluation of Grant Ramsey’s taxonomy of altruism, which includes biological altruism, psychological altruism, and helping altruism, proves that it is not adequate in categorizing organism’s behaviors. A new taxonomy, with the branches of kin selection, reciprocity, and aesthetic altruism, is presented and explained to clarify the definition of altruism and alleviate confusion about how to describe prosocial behaviors. Both naming systems are …

The Evolutionary Theodicy Problem, Houston Schoonmaker

Dialogue & Nexus

Evolutionary theodicies attempt to explain how innocent suffering, death, and extinction seen throughout the evolutionary process of evolution can coincide with believing in a loving God. Since Darwin, scholars have questioned the importance of studying natural selection at such an intricate level. With the knowledge of natural selection, the fact that great suffering is witnessed across nature permits doubts in discussions regarding a benevolent God that created the universe. In this paper, I begin with background information about evolution, theodicy, and how they are related. I look at two major perspectives: the belief that evolution ameliorates the theodicy problem or …

Neuroscience, Materialism, And The Soul: Limit Questions, Jeremy M. Aymard

Dialogue & Nexus

In light of recent discoveries in neuroscience linking the mind to physical processes, Christian philosophers have resorted to a more materialistic view of the human person, using neuroscience as support for their view that an immaterial soul does not exist. In this essay, I will point out a major flaw in the logic for defending a materialistic view, argue that either a bipartite or tripartite view of the human person is more aligned with Scripture, and hopefully point towards a more reliable means for attaining truth regarding human nature and the soul.

Intelligent Design: Should We Teach It?, Sarah-Kate Oliver

Dialogue & Nexus

Belief about the origins of the universe and mankind is an important aspect of most world religions. While many ‘progressive’ Christians view the Genesis accounts of creation as mythical or allegorical, some ‘fundamentalist’ Christians claim it is a literal and historical account of the origins of life. The scientific community, on the other hand, views Darwin’s Theory of Evolution as the definitive explanation of the origin of all species on Earth including humans. As science has continued to line up behind evolution, it has been integrated into the public school curriculum. The question examined by this paper is: should the …

The Impact Of Anthropocentrism On Christian Environmentalism, Alexis Grasse

Dialogue & Nexus

This paper will discuss the effects of anthropocentrism in Christian theology, doctrine, and environmentalism. The development and history of Christian environmentalism will be examined, with emphasis on the time since the 1960s, when environmentalism came to the forefront in the Western world. Alternative interpretations and worldviews, mainly ecocentrism and biocentrism, will be considered and compared to the prevalent anthropocentric view. I will close with a presentation of two possible means for developing a Christian ecological theology without anthropocentrism. An environmental position most coherent with Christian principles will be left open to the reader; my purpose is to examine the impact …

Human Evolution And Divine Agency, Alexandra Rakestraw

Dialogue & Nexus

Modern Christians often find themselves at a crossroads when confronted with the two predominant understandings of human and universal origins. Plain sense readings of Genesis lead many to believe in a historical six-day creation that occurred in the past ten thousand years while proponents on the other side of the spectrum use current scientific understanding to support a creation that occurs through evolutionary means. How one views human origins has a profound impact on one’s concept of how God works in the cosmos. In this paper, I will lay out a background to better understand the characters of Adam and …

Moral Awareness, Original Sin And The Atonement, Tanner Gregory

Dialogue & Nexus

I will explore how evolution impacts the Christian notion of The Fall of man, and, ultimately, the atonement. Various theories of atonement in the Christian tradition generally assume universal and individual sinfulness in humanity. In some cases, this sinfulness is thought to be the result of a distinct moment of rebellion against God, and is transmitted to all of the descendants of Adam. Here, atonement involves Christ’s sacrifice as the means liberate humanity from the bondage of our sinful nature. Evolution collides with these traditional models. Instead of a creation originally void of death and later corrupted by sin, evolution …

Race Relations: A Dialogue Between Science And Theology On The Basis Of Race, Shanice Latham

Dialogue & Nexus

When the topic of race is breached the emotions expressed can range from extreme feelings of guilt to extreme feelings of anger. Why is a word that is, today, commonly associated with a person’s skin color and other physical characteristics responsible for such strong emotional reactions? Much of the violence, poverty, injustice, and hurt in the world has been and is caused by racial division. With the continued use of such an arbitrary system as race these issues will continue to persist and deteriorate. This paper will explore the origin, as well as scientific and theological perspectives of race and …

“Bone Of My Bones And Flesh Of My Flesh”: A Feminist Analysis Of Christianity, Evolutionary Theory, And The Provenance Of Patriarchy, Heather Bishop

Dialogue & Nexus

While perceived by many as conflicting in nearly every sphere, science and religion both play an important role in the promotion of patriarchal ideologies. My research has found that neither Christianity nor evolutionary theory are inherently patriarchal, neither do they justify patriarchy. Instead, it is the misinterpretation and misuse of these subjects that contribute to the justification of patriarchy for the deep-seated goal of reproductive power. I will show this by analyzing theological themes present throughout the Christian scriptures, as well as investigating findings of evolutionary psychology and hominid ancestry. The implication of this study is that there is no …

Creative Nonnatives: Painting Invasive Insects Of The United States, Monica Tynan

Senior Honors Projects

An invasive species is a nonnative organism that may cause damage to an ecosystem. Invasive species cause problems in an environment by outcompeting native organisms for resources or by feeding upon native species. Invasive insects in particular can harm an ecosystem by consuming foliage and decreasing biodiversity. During my experience at the Preisser Lab at the University of Rhode Island, I witnessed rsthand the damage that invasive insects can do to a tree population, and I learned about how ecosystem dynamics can be disrupted by the introduction of a nonnative species.

My project portrays an aesthetically pleasing visualization of several …

Evolution: A Divine Interaction Between God And Creation, Hanna V. Larracas

Selected Honors Theses

The purpose of this paper is to provide a framework through relational theology for understanding the randomness evident in genetic variation which is an element within evolution. I propose that evolution can be incorporated into a theology of creation by placing evolution in context of the interaction of love between God and creation when interpreted through a framework of relational theology. Relational theology, as engaging God as primarily self-giving and holistically hospitable (towards God’s self in the Trinity and towards creation), provides space for a theological understanding of randomness genetic variation and mutation within the evolutionary process. Chapter 1 discusses …

The Epistemic Status Of Moral Conceptual Truths, Kara D. Boschert

Theses

Evolutionary debunking arguments assume that morality could, conceptually speaking, be about anything. A response to this contention is that there are some moral conceptual truths which counter assertions that we could be in error about basic moral truths. According to proponents of moral conceptual truths, some things, by definition, cannot count as moral. Putative moral conceptual truths, such as “stealing is wrong,” are thought to enjoy a privileged epistemic status because anyone who denies them forfeits their ability to engage in competent moral reasoning. This paper explores whether moral conceptual truths can offer a satisfactory response to the debunkers’ premise …

Playing-With The World: Toy Story's Aesthetics And Metaphysics Of Play, Jonathan Hendricks

USF Tampa Graduate Theses and Dissertations

Pixar’s Toy Story (John Lassiter, 1995) is not just a story about toys and the children that play with them, but a demonstration of how we interact with the world. This thesis looks at the way in which both main children, Andy and Sid, interact with their toys and how this interaction is one that is structured by way of what Martin Heidegger calls “Enframing.” In this modality of playing, toys and other things and entities in the world, and the world itself, appear to the children as on-hand resources for use at any time and can be molded, as …

P24. The Birds And The Beats: Perception Of A Beat In An Avian Model, Brendon Samuels

Western Research Forum

Background: Beat perception is a complex cognitive skill that enables humans to “feel” the beat in music, and is an essential component of synchronization of behavior and dance. The mechanisms in the human brain that facilitate beat perception are not entirely understood, and have only been studied thus far using non-invasive techniques. Some animals, such as songbirds, also seem to be able to detect a beat in rhythms, though this has never been formally tested independent of motor synchronization.

Methods: An operant experiment is used to assess if European starlings, a type of songbird, are capable of categorizing …

Bioethics In The Work Of Ernest Everett Just: + Missing - Some 400 Pages, Theodore Walker

Perkins Faculty Research and Special Events

Biology + ethics = bioethics. Here we see that Howard University biologist Ernest Everett Just (born 1883, died 1941) connected biology to ethics.

According to Just, various forms of specific biology (including especially cell biology) plus “general biology” are necessary for explaining adequately the origin of ethical behaviors. Social ethical behaviors, especially mutual aid and cooperative interactions with others and the environment, are essential to evolutionary advances among living creatures, ranging from humans to cells. Accordingly, theory of ethics (moral theory) should have roots in biology.

Also, Just wrote an unpublished book-length manuscript—“some 400 typed pages” (Just 1940)—on seeking the …

Raising Consciousness About Chicken Consciousness, Bernard Rollin

Animal Sentience

The topics explored by Marino are definitive, and should work well to lay to rest forever the widespread belief that chickens have no personality, are unintelligent, or in any other way lack a mental life.

Chickens’ Brains, Like Ours, Are Lateralized, Lesley J. Rogers

Animal Sentience

This commentary draws attention to yet another attribute that has been instrumental in demonstrating the cognitive abilities of domestic chicks: lateralization of brain function. The discovery of lateralization in domestic chicks was part of the first evidence showing that humans are not unique in this respect. The effects on cognitive ability of sensory stimulation in critical stages of development have implications for the welfare of chicks, as well as other species.

Are Chicken Minds Special?, Rafael Freire, Susan J. Hazel

Animal Sentience

The number of publications on chicken cognition and emotion exceeds that on most birds and is comparable to the number of publications on some more “advanced” mammals. We argue that the chicken is an excellent model for this type of research because of (1) the presence of well-established fundamental mental processes in the chicken, (2) a challenging ethological environment and (3) social pressures that may have facilitated the evolution of cognitive abilities similar to those of some mammals. Marino’s (2017) review provides an excellent foundation for the continued study of complex mental abilities in this species.

Chickening Out Of Change: Will Knowing More About Thinking Chickens Change Public Perceptions?, Ewan Bottomley, Steve Loughnan

Animal Sentience

This commentary examines the next step in Marino’s target article – changing people’s attitudes and beliefs about chickens. The scientific case seems clear: chickens are far more complex, psychologically and socially, than originally thought. Marino suggests we use this information to make people feel uncomfortable about their dietary choices in the hope of changing them. We review the psychological literature, examining how people maintain meat consumption despite the clash with their moral beliefs (the “meat paradox”). This work highlights the important gap between what science knows about animals and what people think about animals.

Evolutionary Continuity, Anne Benvenuti

Animal Sentience

The principle of evolutionary continuity states that all animal capacities and behaviors exist — with variations in degree — in continuity with other species. Rather than assuming discontinuity, we should ask why any behavior observed in humans would not be found in at least some other sentient animals under similar conditions. In the case of suicide, the more pertinent issue might be the ethical one: our human responsibility for creating conditions under which other animals might deliberately seek to end their own lives.

Non-Human Animal Suicide Could Be Tested, David Lester

Animal Sentience

Schaefer (1967) showed that mice can discriminate live from dead mice and lethal from nonlethal environments, and that they avoid a lethal environment; but the experiment lacked some controls. This might be a way to test whether mice would ever choose a lethal environment. Humans may also choose a potentially lethal environment unconsciously.

Understanding Animal Suicide And Death Can Lead To Better End-Of-Life Care, Jessica Pierce

Animal Sentience

Peña-Guzmán’s target article on animal suicide will help inform end-of-life care for animals by emphasizing the need for a broad research focus on animal thanatology. Greater scientific understanding of the continuum of death-related awareness, experiences, and behaviors will help us improve veterinary care for animals at the end of life.

Complicated Grief, Teya Brooks Pribac

Animal Sentience

My commentary discusses complicated grief and the ensuing sense of helplessness that may lead to suicide. I close with a story about a pygmy pig.

Can Nonhuman Animals Commit Suicide?, David M. Peña-Guzmán

Animal Sentience

Many people believe that only humans have the cognitive and behavioral capacities needed for suicidal behavior, such as reflexive subjectivity, free will, intentionality, or awareness of death. Three counterarguments — based on (i) negative emotions and psychopathologies among nonhuman animals, (ii) the nature of self-destructive behavior, and (iii) the problem of model fidelity in suicide research — suggest that self-destructive and self-injurious behaviors among human and nonhuman animals vary along a continuum.

Sentience Does Not Require “Higher” Cognition, Giorgio Vallortigara

Animal Sentience

I agree with Marino (2017a,b) that the cognitive capacities of chickens are likely to be the same as those of many others vertebrates. Also, data collected in the young of this precocial species provide rich information about how much cognition can be pre-wired and predisposed in the brain. However, evidence of advanced cognition — in chickens or any other organism — says little about sentience (i.e., feeling). We do not deny sentience in human beings who, because of cognitive deficits, would be incapable of exhibiting some of the cognitive feats of chickens. Moreover, complex problem solving, such as transitive inference, …

Misperceiving And Underestimating The Ubiquitous Chicken, Carrie P. Freeman

Animal Sentience

Marino has provided an accurate and nuanced view about chickens’ complex capabilities as sentient individuals. I explore the implications of these findings for scholars as well as for activists in the protection of farmed animals.
