The central task of cognitive neuroscience to map cognitive capacities to neural mechanisms faces three interlocking conceptual problems that together frame the problem of cognitive ontology. First, they must establish which tasks elicit which cognitive capacities, and specifically when different tasks elicit the same capacity. To address this operationalization problem, scientists often assess whether the tasks engage the same neural mechanisms. But to determine whether mechanisms are of the same or different kinds, we need to solve the abstraction problem by (...) determining which mechanistic differences are and are not relevant, and also the boundary problem by distinguishing the mechanism from its background conditions. Solving these problems, in turn, requires understanding how cognitive capacities are elicited in tasks. These three problems, which have been noted and discussed elsewhere in the literature, together form a ‘cycle of kinds’ that frames the central problem-space of cognitive ontology. We describe this cycle to clarify the intellectual challenges facing the cognitive ontologist and to reveal the kind of iterative process by which ontological revision in cognitive neuroscience is likely to unfold.

Subliminal primes are assumed to produce weaker and short-lived effects on subsequent behavior compared to clearly visible primes. However, this difference in priming effect may be due to differences in signal strength, rather than level of awareness. In the present study we manipulated prime discriminability by using metacontrast masks and pseudomasks, while keeping the prime strength equal. This manipulation resulted in large differences in discriminability of the primes. However, both immediate response priming and long-term response priming was equal for the (...) poorly discriminable and well discriminable primes, and equal for groups that differed markedly in terms of how well they could discriminate the primes. Our findings imply that discriminability of information is independent of both the immediate and long-term effects that information can have on behavior. (shrink)

The New Neurophilosophy: An Introduction to the ANTW special issue Contemporary neurophilosophy is more pragmatic than the early neurophilosophy of the 1980’s. It features two implicit ideas: First, commonsense cognitive concepts (CCC’s) like ‘free will’, ‘thoughts’, ‘consciousness’, ‘attention’ and ‘self’, belong to a variety of disciplines and cannot be appropriated by either philosophy or cognitive neuroscience. Second, the description of biological processes in the brain and the description of behavioral processes by CCC’s are so far removed from each other that (...) a simple reduction, or even a relation of implementation between them, is implausible. What is needed instead, is a relation of interpretation: which cognitive concepts should be used to describe specific brain processes is not fixed in advance but the outcome of an ongoing negotiation between common sense practice, philosophy, and cognitive neuroscience. All articles in this special issue shed light on these two key ideas that characterize a new neurophilosophy. (shrink)

Most of the historically salient versions of the Cosmological Argument rest on two assumptions. The first assumption is that some contingeney (i.e., contingent fact) is such that a necessity is required to explain it. Against that assumption we will argue that necessities alone cannot explain any contingency and, furthermore, that it is impossible to explain the totality of contingencies at all.The second assumption is the Principle of Sufficient Reason. Against the Principle of Sufficient Reason we will argue that it is (...) unreasonable to require, as the Principle of Sufficient Reason does, that any given whole of contingent facts has an explanation. Instead, it depends on the results of empirical investigation whether or not one should ask for an explanation of the given whole.We argue that if a cosmological argument invokes either of the two assumptions, then it fails to prove that a necessity is needed to explain the universe of contingent facts.

I argue that there cannot be a sense attached to “could have done otherwise” that is both compatible with the truth of determinism and relevant to the question of free will. Then I develop an incompatibilist response to the common objection that the incompatibilist requires of free actions that they have no causes and therefore cannot be anything for which an agent can be responsible. In the process, I bring out a similarity between compatibilism and incompatibilism in respect of where (...) their problem lies. (shrink)

This book closely examines our commonly held beliefs about human suffering, and offers unique insights into God's role in why we suffer. Dr. Perri critically examines what it means to be human from a Judeo-Christian perspective, and extrapolates from the work of Carl Gustav Jung showing a deeply complex development of human transcendence in human suffering. On an interpersonal level, Dr. Perri elaborates on the work of Martin Buber and Emanuel Levinas and shows how our suffering can be shared and (...) lessened by our unconditionality and presence for the other. Scriptural passages are quoted from both the Hebrew and New Testament texts, and are used to depict the suffering of humankind as seen in the face of Job. It was this face, according to Perri, that Jesus saw in the faces of those He came to redeem, and that ultimately brought Him to the crucifix of redemption. Dr. Perri challenges Sartre's position that our existence precedes our essence, and draws on the work of Abraham Joshua Heschel and Christian theology in this regard. He further elaborates a neurodevelopmental paradigm that creates essence as the basis of our freedom to choose. This book can be read and studied by both professionals in the helping and healing professions, and lay persons seeking to better understand our suffering, and how to better help those who suffer. Dr. Perri offers specific ways in how to be present for those who suffer, how to read and receive the hidden language of human suffering, and how to use silence as a communication skill. (shrink)

A target question for the scientific study of consciousness is how dimensions of consciousness, such as the ability to feel pain and pleasure or reflect on one’s own experience, vary in different states and animal species. Considering the tight link between consciousness and moral status, answers to these questions have implications for law and ethics. Here we point out that given this link, the scientific community studying consciousness may face implicit pressure to carry out certain research programs or interpret results (...) in ways that justify current norms rather than challenge them. We show that because consciousness largely determines moral status, the use of nonhuman animals in the scientific study of consciousness introduces a direct conflict between scientific relevance and ethics—the more scientifically valuable an animal model is for studying consciousness, the more difficult it becomes to ethically justify compromises to its well-being for consciousness research. Finally, in light of these considerations, we call for a discussion of the immediate ethical corollaries of the body of knowledge that has accumulated and for a more explicit consideration of the role of ideology and ethics in the scientific study of consciousness.

The draft Code of Conduct for Research is an important initiative towards assisting the scientific community in complying with the provisions of the Protection of Personal Information Act 4 of 2013 (POPIA). However, its approach towards cross-border data sharing should be reconsidered to clarify the ambiguities inherent in the legal requirements for the cross-border sharing of health data in the POPIA. These ambiguities include the concept of ‘transfer of information’, the application of adequacy as a legal mechanism for transfer, the (...) nature of consent for cross-border sharing and the scope of the recipient third party. We suggest that the draft Code of Conduct for Research can be improved by: Explaining or defining the concept of ‘transfer of information’ and when it applies to cross-border sharing in research Clarifying the application of adequacy as a legal mechanism for transfer vis-à-vis the other alternatives Expanding on the interpretation and application of consent as a legal mechanism for cross-border transfers Expanding the category of persons who may be recipients of personal information in a third country.

Language, like other human traits, could only have evolved during one or more stages of development. We enlist the theoretical framework of human life history to account for certain aspects of linguistic evolution, with special reference to initial phases in the process. It is hypothesized that selection operated at several developmental stages, the earlier ones producing new behaviors that were reinforced by additional, and possibly more powerful, forms of selection during later stages, especially adolescence and early adulthood. Peer commentaries have (...) provided opportunities to explain human life history more comprehensively, and to add details to our account of spoken language. We made no attempt to explain syntax in the target article, but we propose here that selection for “vocal plumage” may have increased our species’ capacity for utterance complexity, a development that would have benefited all levels of language.

In this timely book L.W. Sumner addresses these issues within the wider context of palliative care for patients in the dying process.

The genetic modification of pigs as a source of transplantable organs is one of several possible solutions to the chronic organ shortage. This paper describes existing ethical tensions in xenotransplantation (XTx) that argue against pursuing it. Recommendations for lifelong infectious disease surveillance and notification of close contacts of recipients are in tension with the rights of human research subjects. Parental/guardian consent for pediatric xenograft recipients is in tension with a child’s right to an open future. Individual consent to transplant is (...) in tension with public health threats that include zoonotic diseases. XTx amplifies concerns about justice in organ transplantation and could exacerbate existing inequities. The prevention of infectious disease in source animals is in tension with the best practices of animal care and animal welfare, requiring isolation, ethologically inappropriate housing, and invasive reproductive procedures that would severely impact the well-being of intelligent social creatures like pigs.

Rationality requires us to respond to apparent normative reasons. Given the independence of appearance and reality, why think that apparent normative reasons necessarily provide real normative reasons? And if they do not, why think that mistakes of rationality are necessarily real mistakes? This paper gives a novel answer to these questions. I argue first that in the moral domain, there are objective duties of respect that we violate whenever we do what appears to violate our first-order duties. The existence of (...) these duties of respect, I argue, ensures that apparent moral reasons are exceptions to the independence of appearance and reality. I then extend these arguments to the domain of overall reason. Just as there are objective duties of respect for moral reasons that explain moral blameworthiness, so there are objective duties of respect for reasons that explain blameworthiness in the court of overall reason. The existence of these duties ensures that apparent reasons are exceptions to the independence of appearance and reality. (shrink)
