On the Structure of Bioethics as a Pragmatic Discipline

This article analyzes certain aspects of the structure of bioethics as a discipline. It begins by arguing that bioethics is an academic discipline of a pragmatic nature and then puts forward a classification of the main problems, issues, and concerns in bioethics, using this classification as a way to outline the limits and framework of the field. Pushing further, it contends that comprehensive treatment of any topic in bioethics requires that three normative dimensions (the ethical, the moral, and the political) be taken into account. It concludes that the classification of the issues and analysis of each issue's normative dimensions can provide valuable contributions toward understanding the sui generis structure of bioethics as a pragmatic discipline.     

Applying Philosophy: A Response to O'Neill

abstract   I consider the putative originality of applied philosophy and seek to defend a version of it often called 'bottom up'. I review ways in which imagined cases may cause us to reconsider our normative commitments, and endorse a general attentiveness to the matter of how the world is and how it might reasonably be imagined. This is important if practical philosophers want to form the correct normative judgements, to be able to recognize the sui generis character of some moral theorising in particular domains, practically to enact their considered judgments, and properly to acknowledge how the real world, in the form of institutions, practices and a cultural framework, constrains, or facilitates, practical enactment. Throughout I illustrate my abstract claims by reference to the moral judgement and legal regulation of sexual behaviour .     

Realist ethical naturalism for ethical non-naturalists

It is common in metaethics today to draw a distinction between “naturalist” and “non-naturalist” versions of moral realism, where the former view maintains that moral properties are natural properties, while the latter view maintains that they are non-natural properties instead. The nature of the disagreement here can be understood in different ways, but the most common way is to understand it as a metaphysical disagreement. In particular, the disagreement here is about the reducibility of moral properties, where the “naturalists” maintain that moral properties are in some way reducible to the lower-level natural properties on which they supervene, while the “non-naturalists” maintain that moral properties are sui generis and robustly irreducible. In this paper I present a novel version of realist ethical naturalism—a view that I call Emergentist Ethical Naturalism—that reveals this common way of understanding the distinction between naturalism and non-naturalism to be flawed by combining a commitment to ethical naturalism with a commitment to the sui generis and robustly irreducible nature of moral properties that typically defines non-naturalism. Then, after presenting the theory and addressing a few worries that one might have about it, I show how it offers some novel, emergence-based responses to the various supervenience challenges that plague moral realism and thereby gives the ethical naturalist a robustly non-reductive option for dealing with these challenges.     

Why property dualists must reject substance physicalism

I argue that property dualists cannot hold that minds are physical substances. The focus of my discussion is a property dualism that takes qualia to be sui generis features of reality.     

Semantic Primitivism and Normativity

Kripke-Wittgenstein meaning scepticism appears as a serious threat to the idea that there could be meaning-constituting facts. Some people argue that the only viable response is to adopt semantic primitivism (SP). SP is the doctrine that meaning-facts are sui generis and irreducibly semantic. The idea is that by allowing such primitive semantic facts into our ontology Kripke's sceptical paradox cannot arise. I argue that SP is untenable in spite of its apparent resourcefulness. No version of SP can account for the normative and practical aspects of meaning while remaining non-reductive. A sparse, basic SP does not adequately deal with the sceptical paradox. A richer SP, with an added intuitive epistemology, can only explain the practical aspect of meaning by aligning itself with reductive use-based accounts of meaning. SP with essential relations between meanings and meaning-bearers could possibly avoid these problems, but we have no reason to think such a version of SP is really non-reductive. I conclude that Kripke-Wittgenstein meaning scepticism should not lead us to adopt SP, instead we should re-examine use-based, dispositionalist accounts of meaning.     

Expressivism and the Reliability Challenge

Suppose that there are objective normative facts and our beliefs about such facts are by-and-large true. How did this come to happen? This is the reliability challenge to normative realism. As has been recently noted, the challenge also applies to expressivist “quasi-realism”. I argue that expressivism is useful in the face of this challenge, in a way that has not been yet properly articulated. In dealing with epistemological issues, quasi-realists typically invoke the desire-like nature of normative judgments. However, this is not enough to prevent the reliability challenge from arising, given that quasi-realists also hold that normative judgments are truth-apt beliefs. To defuse this challenge, we need to isolate a deeper sense in which normative thought is not representational. I propose that we rely on the negative functional thesis of expressivism: normative thought does not have the function of tracking normative facts, or any other kind of facts. This thesis supports an argument to the effect that it is misguided to expect an explanation of our access to normative facts akin to the explanations available in regions of thought that have a tracking function. We should be content with explanations of our reliability that take for granted certain connections between our psychology and the normative truths.     

The neuropsychology of religious experience. A review of different scientific approaches to the phenomenon / Neuropsicología de la experiencia religiosa. Una revisión de distintas aproximaciones científicas al fenómeno

Abstract

The current article is a critical review of the neuropsychological study of religious experience. First, we analyse the philosophical and theological roots of the term and its characterization as a sui generis and unique phenomenon. We subsequently describe the adoption of the concept in psychology, as well as the emergence of alternative approaches that emphasize the role of categorization of experiences as religious. We then move on to explore how both approaches have influenced the neuropsychological study of religious experience, consequently producing different models: sui generis, attributional and others that consider the variety of factors and the heterogeneity of experiences associated with religious practices.     

Essentially Grounded Non-Naturalism and Normative Supervenience

Non-naturalism—roughly the view that normative properties and facts are sui generis and incompatible with a purely scientific worldview—faces a difficult challenge with regard to explaining why it is that the normative features of things supervene on their natural features. More specifically: non-naturalists have trouble explaining the necessitation relations, whatever they are, that hold between the natural and the normative. My focus is on Stephanie Leary’s recent response to the challenge, which offers an attempted non-naturalism-friendly explanation for the supervenience of the normative on the natural by appealing to hybrid properties, the essences of which link them to both natural and sui generis normative properties in suitable ways. I argue that despite its ingenuity, Leary’s solution fails. This is so, I claim, because there are no hybrid properties of the sort that her suggestion appeals to. If non-naturalists are to deal with the supervenience challenge, they will have to find another way of doing so.     

GOD AS A COMMUNICATIVE SYSTEM SUI GENERIS: BEYOND THE PSYCHIC, SOCIAL, PROCESS MODELS OF THE TRINITY

With an aim to develop a public theology for an age of information media (or media theology), this article proposes a new God-concept: God is a communicative system sui generis that autopoietically processes meaning/information in the supratemporal realm via perfect divine media ad intra (Word/Spirit). For this task, Niklas Luhmann's systems theory is critically appropriated in dialogue with theology. First, my working postmetaphysical/epistemological stance is articulated as realistic operational constructivism and functionalism. Second, a series of arguments are advanced to substantiate the thesis: (1) God is an observing system sui generis ; (2) self-referential communication is divine operation; (3) unsurpassable complexity is divine mystery; (4) supratemporal autopoiesis of meaning is divine processing; (5) agape is the symbolic medium of divine communication. Third, this communicative model of God is developed into a trinitarian theology, with a claim that this model offers a viable alternative beyond the standard (psychic, social, process) models. Finally, some implications of this model are explored for constructive theology (conceiving creation as divine mediatization) and for science-and-religion in terms of derivative models: (1) God as a living system sui generis and (2) God as a meaning system sui generis .     

Neural Computation and the Computational Theory of Cognition

We begin by distinguishing computationalism from a number of other theses that are sometimes conflated with it. We also distinguish between several important kinds of computation: computation in a generic sense, digital computation, and analog computation. Then, we defend a weak version of computationalism—neural processes are computations in the generic sense. After that, we reject on empirical grounds the common assimilation of neural computation to either analog or digital computation, concluding that neural computation is sui generis. Analog computation requires continuous signals; digital computation requires strings of digits. But current neuroscientific evidence indicates that typical neural signals, such as spike trains, are graded like continuous signals but are constituted by discrete functional elements (spikes); thus, typical neural signals are neither continuous signals nor strings of digits. It follows that neural computation is sui generis. Finally, we highlight three important consequences of a proper understanding of neural computation for the theory of cognition. First, understanding neural computation requires a specially designed mathematical theory (or theories) rather than the mathematical theories of analog or digital computation. Second, several popular views about neural computation turn out to be incorrect. Third, computational theories of cognition that rely on non‐neural notions of computation ought to be replaced or reinterpreted in terms of neural computation.     

Kant and Kantians on “the Normative Question”

After decades of vigorous debate, many contemporary philosophers in the Kantian tradition continue to believe, or at least hope, that morality can be given a firm grounding by showing that rational agents cannot consistently reject moral requirements. In the present paper, I do not take a stand on the possibility of bringing out the alleged inconsistency. Instead I argue that, even if a successful argument could be given for this inconsistency, this would not provide an adequate answer to “the normative question” (i.e., “why should I be moral?”). My defense of this claim emerges from a defense of a claim about Kant, namely, that he did not attempt to answer the normative question in this way. After carefully articulating Kant’s answer to the normative question, I argue that his answer to this question contains a lesson about why we should not embrace the approach that is popular among many contemporary Kantians.
