Do motivational limitations due to human nature constrain the demands of justice? Among those who say no, David Estlund offers perhaps the most compelling argument. Taking Estlund’s analysis of “ability” as a starting point, I show that motivational deficiencies can constrain the demands of justice under at least one common circumstance — that the motivationally-deficient agent makes a good faith effort to overcome her deficiency. In fact, my argument implies something stronger; namely, that the demands of justice are constrained (...) by what people are sufficiently likely to be motivated to do. Thus, contrary to the prevailing wisdom, it is the business of ideal theory — not just nonideal theory — to work with the motivational capacities people are likely enough to have. (See also Estlund's reply in the same issue of EJPT and my rejoinder on Philpapers.). (shrink)

The lattice operations of join and meet were defined for set partitions in the nineteenth century, but no new logical operations on partitions were defined and studied during the twentieth century. Yet there is a simple and natural graph-theoretic method presented here to define any n-ary Boolean operation on partitions. An equivalent closure-theoretic method is also defined. In closing, the question is addressed of why it took so long for all Boolean operations to be defined for partitions.

Cognitive categories in the geographic realm appear to manifest certain special features as contrasted with categories for objects at surveyable scales. We have argued that these features reflect specific ontological characteristics of geographic objects. This paper presents hypotheses as to the nature of the features mentioned, reviews previous empirical work on geographic categories, and presents the results of pilot experiments that used English-speaking subjects to test our hypotheses. Our experiments show geographic categories to be similar to their non-geographic counterparts in (...) the ways in which they generate instances of different relative frequencies at different levels. Other tests, however, provide preliminary evidence for the existence of important differences in subjects’ categorizations of geographic and non-geographic objects, and suggest further experimental work especially with regard to the role in cognitive categorization of different types of object-boundaries at different scales.

We provide conditions under which an incomplete strongly independent preorder on a convex set X can be represented by a set of mixture preserving real-valued functions. We allow X to be infi nite dimensional. The main continuity condition we focus on is mixture continuity. This is sufficient for such a representation provided X has countable dimension or satisfi es a condition that we call Polarization.

A strongly independent preorder on a possibly in finite dimensional convex set that satisfi es two of the following conditions must satisfy the third: (i) the Archimedean continuity condition; (ii) mixture continuity; and (iii) comparability under the preorder is an equivalence relation. In addition, if the preorder is nontrivial (has nonempty asymmetric part) and satisfi es two of the following conditions, it must satisfy the third: (i') a modest strengthening of the Archimedean condition; (ii') mixture continuity; and (iii') completeness. Applications (...) to decision making under conditions of risk and uncertainty are provided. (shrink)

Abstract creationism about fictional characters is the view that fictional characters are abstract objects that authors create. I defend this view against criticisms from Stuart Brock that hitherto have not been adequately countered. The discussion sheds light on how the number of fictional characters depends on authorial intention. I conclude also that we should change how we think intentions are connected to artifacts more generally, both abstract and concrete.

In Human Nature and the Limits of Political Philosophy, I argued that justice might require things of people that they cannot bring themselves to do. A central step was to argue that this does not entail an inability to ‘do’ the putatively required thing. David Wiens challenges that argument of mine, and this piece is my reply.

In this paper, we present three necessary conditions for morally responsible animal research that we believe people on both sides of this debate can accept. Specifically, we argue that, even if human beings have higher moral status than nonhuman animals, animal research is morally permissible only if it satisfies (a) an expectation of sufficient net benefit, (b) a worthwhile-life condition, and (c) a no unnecessary-harm/qualified-basic-needs condition. We then claim that, whether or not these necessary conditions are jointly sufficient conditions of (...) justified animal research, they are relatively demanding with the consequence that many animal experiments may fail to satisfy them.

I offer an account of how ideals motivate us. My account suggests that although emulating an ideal is often rational, it can lead us to do irrational things. * This is the third in a series of four papers on narrative self-conceptions and their role in moral motivation. In the first paper, “The Self as Narrator” (to appear in Autonomy and the Challenges to Liberalism: New Essays, ed. Joel Anderson and John Christman), I explore the motivational role of narrative self-conceptions, (...) drawing on Daniel Dennett’s notion of the self as a “center of narrative gravity”. In the second paper, “Willing the Law” (in Practical Conflicts, ed. Monika Betzler and Peter Baumann [Cambridge: Cambridge University Press, forthcoming]), I explore the role of selfconceptions in Kantian “conflicts in the will”, drawing on Christine Korsgaard’s notion of “practical identities”. In a fourth paper, “A Sense of Self” (ms), I explore the role of narrative self-con-ceptions in Kantian “conflicts in conception”, drawing on the work of Thomas Nagel and John Perry on the self.

In the 1990s, a debate raged across the whole postsocialist world as well as in Western development agencies such as the World Bank about the best approach to the transition from various forms of socialism or communism to a market economy and political democracy. One of the most hotly contested topics was the question of the workplace being organized based on workplace democracy (e.g., various forms of worker ownership) or based on the conventional employer-employee relationship. Well before 1989, many of (...) the socialist countries had started experimenting with various forms of "self-management" operating in more of a market setting, Yugoslavia being the most developed example. Thus one "path to the market" would .. (shrink)

Normative moral theories are frequently invoked to serve one of two distinct purposes: (1) explicate a criterion of rightness, or (2) provide an ethical decision-making procedure. Although a criterion of rightness provides a valuable theoretical ideal, proposed criteria rarely can be (nor are they intended to be) directly translated into a feasible decision-making procedure. This paper applies the computational framework of bounded rationality to moral decision-making to ask: how ought a bounded human agent make ethical decisions? We suggest agents ought (...) to follow moral maxims: principles that approximate rightness in many situations, but that can be overridden in specific, precisely describable circumstances. While this intuitive idea has been proposed many times before, we provide a precise model of how maxim consequentialism functions as an approximation to an act-consequentialist criterion of rightness, while maintaining the flexibility and defeasibility that has eluded most forms of rule consequentialism. Furthermore, while our overarching aim is to propose a new normative standard of moral decision-making, we demonstrate how maxim consequentialism can also function as a descriptive account of human behavior. We conclude by noting that different criteria of rightness may lead to different maxim-based ethics. (shrink)

This paper explores the human experience of game-playing and its implications for artificial intelligence. The author uses phenomenology to examine game-playing from a human-centered perspective and applies it to language games played by artificial intelligences and humans. The paper argues that AI cannot truly play games because it lacks the intentionality, embodied experience, and social interaction that are fundamental to human game-playing. Furthermore, current AI lacks the ability to converse, which is argued to be equivalent to Wittgenstein’s view of engaging (...) in “language games.” The author presents a formal ontology of game playing, agents, and their intentional states, and contrasts human agents playing games with artificial agents “playing games.” The paper concludes that while artificial intelligence can simulate some aspects of human language games, it lacks the essential capacities for game playing, such as cognition, creativity, will, intentionality, understanding, and personhood.

Inspired by recent progress in multi-agent Reinforcement Learning (RL), in this work we examine the collective intelligent behaviour of theoretical universal agents by introducing a weighted mixture operation. Given a weighted set of agents, their weighted mixture is a new agent whose expected total reward in any environment is the corresponding weighted average of the original agents' expected total rewards in that environment. Thus, if RL agent intelligence is quantified in terms of performance across environments, the weighted mixture's intelligence is (...) the weighted average of the original agents' intelligences. This operation enables various interesting new theorems that shed light on the geometry of RL agent intelligence, namely: results about symmetries, convex agent-sets, and local extrema. We also show that any RL agent intelligence measure based on average performance across environments, subject to certain weak technical conditions, is identical (up to a constant factor) to performance within a single environment dependent on said intelligence measure.

Peter van Inwagen's Direct Argument (DA) purports to establish the incompatibility of determinism and moral responsibility, without appealing to the notion of avoidability, a notion on whose analysis compatibilists and incompatibilists disagree. Van Inwagen intended DA to refute compatibilism, or at least to shift the burden of proof onto the compatibilist. In this paper, we offer a critical assessment of DA. We examine a variety of objections to DA due to John Fischer and Mark Ravizza, Ishtiyaque Haji, Seth Shabo, Michael (...) McKenna, and David Widerker. We divide these objections into those based on dialectical considerations (section 1), and objections in the form of counterexamples to a central principle which the Direct Argument employs (sec 2). The conclusion we reach is that the proponent of DA can deal plausibly with these objections, thus establishing DA as a powerful argument in favor of incompatibilism. (shrink)

In a study that goes beyond the ego affirmed by Freudian psychology, David Levin offers an account of personal growth and self-fulfillment based on the development of our capacity for listening. Drawing on the work of Dewey, Piaget, Erikson, and Kohlberg, he uses the vocabulary of phenomenological psychology to distinguish four stages in this developmental process and brings us the significance of these stages for music, psychotherapy, ethics, politics, and ecology. This analysis substantiates his claim that the development of (...) our listening capacity is a process that fits Foucault's conception of a practice of the self, forming our character as social beings and moral agents. David Levin contends that our self- development as auditory beings is necessary for the achievement of a just and democratic society. (shrink)

There has recently been emphasis put on providing two-factor accounts of monothematic delusions. Such accounts would explain (1) whether a delusional hypothesis (e.g. someone else is inserting thoughts into my mind) can be understood as a prima facie reasonable response to an experience and (2) why such a delusional hypothesis is believed and maintained given its implausibility and evidence against it. I argue that if we are to avoid obfuscating the cognitive mechanisms involved in monothematic delusion formation we should split (...) the first factor (1 above) into two factors: how abnormal experience can give rise to a delusional ‘proto-hypothesis’ and how a ‘proto-hypothesis’ in consort with normal experiences and background information, can be developed into a delusional hypothesis. In particular I will argue that a schizophrenic is faced with the unusual requirement of having to identify an introspectively accessible thought as one's own, and that this requirement of identification is the central experiential abnormality of thought insertion, auditory verbal hallucination, and alien control (i.e. passivity symptoms). Additionally, I will consider non-experiential factors which are required for the formation of a delusional hypothesis. (shrink)

A reply to Melissa Lane's "Antianarchia: interpreting political thought in Plato" In these comments I focus on how to think of antianarchia as an element of Plato's political thought, and in doing so raise some methodological questions about how to read Plato’s dialogues, focusing on what is involved in attributing views to Plato in general.

Humour is worthy of serious ethical consideration. However, it is often taken far too seriously. In this paper, it is argued that while humour is sometimes unethical, it is wrong much less often than many people think. Non-contextual criticisms, which claim that certain kinds of humour are always wrong, are rejected. Contextual criticisms, which take issue with particular instances of humour rather than types of humour, are more promising. However, it is common to overstate the number of contexts in which (...) humour is wrong. Various mistakes of this kind are highlighted and cautioned against. (shrink)

The traditional doctrine of divine omniscience ascribes to God the fully exercised power to know all truths. but why is God’s excellence with respect to knowing not treated on a par with his excellence with respect to doing, where the latter requires only that God have the power to do all things? The prima facie problem with divine ”omni-knowledgeability’ -- roughly, being able to know whatever one wants to know whenever one wants to know it -- is that knowledge requires (...) an internal representation, whereas mere ”knowledgeability’ does not. I argue to the contrary that knowledge does not require an internal representation, and that even if it did, an omni-knowledgeable God would satisfy this requirement. omni-knowledgeability therefore represents a distinct understanding of God’s cognitive excellence while satisfying the traditional insistence on full omniscience.

Category theory has foundational importance because it provides conceptual lenses to characterize what is important and universal in mathematics—with adjunctions being the primary lens. If adjunctions are so important in mathematics, then perhaps they will isolate concepts of some importance in the empirical sciences. But the applications of adjunctions have been hampered by an overly restrictive formulation that avoids heteromorphisms or hets. By reformulating an adjunction using hets, it is split into two parts, a left and a right semiadjunction. Semiadjunctions (...) (essentially a formulation of universal mapping properties using hets) can then be combined in a new way to define the notion of a brain functor that provides an abstract model of the intentionality of perception and action (as opposed to the passive reception of sense-data or the reflex generation of behavior).

Parts of the genome of a single individual can have conflicting interests, depending on which parent they were inherited from. One mechanism by which these conflicts are expressed in some taxa, including mammals, is genomic imprinting, which modulates the level of expression of some genes depending on their parent of origin. Imprinted gene expression is known to affect body size, brain size, and the relative development of various tissues in mammals. A high fraction of imprinted gene expression occurs in the (...) brain. Biologists including Hamilton, Trivers and Haig have proposed that this may explain some intrapersonal conflict in humans. This speculation amounts to an inference from conflict within the genome to conflict within the brain or mind. This is a provocative proposal, which deserves serious attention. In this paper I assess aspects of Haig’s version of the proposal. I argue, first, that the notion that intragenomic conflict predicts personal inconsistency should be rejected. Second, while it is unlikely that it credibly predicts sub-personal agents representing conflicting genetic interests, it is plausible that it predicts that the division of cognitive labour could be exploited to turn sub-systems into proxies for conflicting interests.

If we have no transparent access to our self, what kind of self-criticism is possible? Neither modernists nor postmodernists yet this pragmatic issue correct.

The essay offers a thought experiment to try to clarify our distinction between our naïve ancestors and our sophisticated moderns. The effect of the thought experiment is to cast doubt upon the distinction and examine further our own myths about our ancestors. And to wonder at what it means to be truly modern.

This is a book about evolution from a post-Darwinian perspective. It recounts the core ideas of French philosopher Henri Bergson and his rediscovery and legacy in the poststructuralist critical philosophies of the 1960s, and explores the confluences of these ideas with those of complexity theory in environmental biology. The failings in the development of systems theory, many of which complex systems theory overcomes, are retold; with Bergson, this book proposes, some of the rest may be overcome too. It asserts that (...) Bergson’s ideas can further our understanding of evolution, and of complex systems, and aid the work of scientists working in the field of ecological complexity. See http://www.creativeemergence.info/ for more detail and sample chapter. "The claim is that Bergson's notions of duration and élan vital resonate with and provide interesting metaphysical speculations complementing a process structuralist biology of the Goodwin and Kauffman stripe. This is certainly provocative and worth further thought. The key claim is that the openness and unpredictability of systems "at the edge of chaos" (where a system can be said to "choose" at bifurcation points in its state space) meets the Bergsonian desideratum of an open universe that takes irreversible time and evolutionary difference seriously. In particular, Kreps stresses the way Bergson's insistence on the differentiating force of élan vital (which Kreps successfully defends from the charge of a substantialist vitalism along the lines of Hans Dreisch) puts him in line with those who see natural selection as a secondary pruning of a primary differentiation." -John Protevi, Notre Dame Philosophical Reviews 2016.01.20 'This is no ordinary introduction to Henri Bergson. What David Kreps' excellent study gives us is Bergson, complexe: first, because there is no simple way to take (or leave) Bergson's ideas - his thought of durée, élan, and 'multiplicity' demands the most subtle and nuanced reading to give them their full justice; and second, because only by intertwining his ideas with the most up-to-date research in systems thinking, complexity theory, and poststructuralism can we begin to understand their absolute contemporaneity. Kreps' work does all this and more: it gives us the Bergson we need for today.' -John Mullarkey, author of Bergson and Philosophy 'Kreps' book is a thoroughly researched and well-written work that shows how Bergson's philosophy of evolution and time can also reinvigorate our ideas about complexity and organization in the natural and physical sciences.' -Stephen Crocker, author of Bergson and the Metaphysics of Media.

The goal or criterion of "authenticity" for judging a change in art or ethics or culture is notoriously vague and can be dangerous. This essay proposes a version of authenticity based on a quasi-Hegelian version of the process of development rather than on any specific patrimony to be preserved. Oddly enough, the proposed criterion has many similarities with one proposed by a staunch anti-Hegelian, Gilles Deleuze.

Since the pioneering work of Birkhoff and von Neumann, quantum logic has been interpreted as the logic of (closed) subspaces of a Hilbert space. There is a progression from the usual Boolean logic of subsets to the "quantum logic" of subspaces of a general vector space--which is then specialized to the closed subspaces of a Hilbert space. But there is a "dual" progression. The notion of a partition (or quotient set or equivalence relation) is dual (in a category-theoretic sense) to (...) the notion of a subset. Hence the Boolean logic of subsets has a dual logic of partitions. Then the dual progression is from that logic of partitions to the quantum logic of direct-sum decompositions (i.e., the vector space version of a set partition) of a general vector space--which can then be specialized to the direct-sum decompositions of a Hilbert space. This allows the logic to express measurement by any self-adjoint operators rather than just the projection operators associated with subspaces. In this introductory paper, the focus is on the quantum logic of direct-sum decompositions of a finite-dimensional vector space (including such a Hilbert space). The primary special case examined is finite vector spaces over ℤ₂ where the pedagogical model of quantum mechanics over sets (QM/Sets) is formulated. In the Appendix, the combinatorics of direct-sum decompositions of finite vector spaces over GF(q) is analyzed with computations for the case of QM/Sets where q=2. (shrink)

In this paper, I motivate skepticism about the causal efficacy of moral properties in two ways. First, I highlight a tension that arises between two claims that moral realists may want to accept. The first claim is that physically indistinguishable things do not differ in any causally efficacious respect. The second claim is that physically indistinguishable things that differ in certain historical respects have different moral properties. The tension arises to the extent to which these different moral properties are supposed (...) to have different effects on people. I will introduce a class of cases in which this tension arises and suggest that the moral properties in these cases have no causal power. I will also question whether there are differences between the moral properties in these cases and moral properties in other cases that do not involve physically indistinguishable things that could make the latter moral properties causally efficacious. The second way that I motivate skepticism consists in pointing out a unique feature of cases in which moral properties are supposed both to supervene on historical properties and to be causally efficacious. These cases allow us to change moral properties with alleged effects while we hold constant the nonmoral candidates for causal contribution to those effects. This feature of these cases is unique because in most other cases the moral properties supervene on the physical properties in the nonmoral candidates, such that we cannot change the former while holding constant the latter. This way of changing moral properties provides empirical grounds for testing their causal efficacy. (shrink)

The theses and program below ask about judgment and tradition in a self-consciously plural world. The little program points down a path I am exploring in a pair of texts, one on notions of identity in the history of philosophy, and one on the identity of buildings and places. The underlying issue of those texts is: what will replace the old notion of a particular identity? Places, persons, and communities do not and have never had such simple identities as our (...) concepts often made them out to have. But our world today defies the application of universal categories and judgments to fixed particulars. Our places and identities become complexly multiplied, they interpenetrate, the electronic no-place / all-place opens before us. Yet at the same time exclusions and particularities assert themselves everywhere. If universal judgment seems unlikely, relativism is one response, but relativism remains within the horizon of universals and particulars. What kinds of identity can provide standpoints for describing and judging today? (shrink)

The undergraduate philosophy major is often seen as an irrelevant degree. While this may be attributed to a number of causes, it is also occasion for academic philosophers to reevaluate pedagogical methods at the undergraduate level. The author evaluates typical pedagogical methods and argues that overemphasizing epistemological goals of philosophical investigation (e.g. truth and justification) instrumentalizes the process of inquiry and stifles students’ philosophical imagination, resulting in the impression of philosophy’s irrelevance. An alternative model is offered on the basis of (...) John Dewey’s pattern of inquiry. It is argued that a pedagogy that attends to Dewey’s five phases of inquiry promotes greater attention to the process of inquiry itself, which emphasizes knowledge as social, open to revision, and pertinent to students’ needs and interests. The author concludes by considering the philosophical implications of implementing such a pedagogy. (shrink)

Actions that are intended to produce harmful consequences can fail to achieve their desired effects in numerous ways. We refer to action sequences in which harmful intentions are thwarted as deviant causal chains. The culpable control model of blame (CCM)is a useful tool for predicting and explaining the attributions that observers make of the actors whose harmful intentions go awry. In this paper, we describe six types of deviant causal chains; those in which: an actor’s attempt is obviated by the (...) intervention of another person or the environment; the intended effects could not have been produced regardless of the actor’s behavior; other causes diminish the actor’s causal role; the actor brings about foreseen but undesired consequences as a result of pursuing his or her focal goal; the focal action produces a chain of increasingly remote causal events; and the actor derives unforeseen benefits from his or her nefarious actions. A basic assumption of the CCM in these cases is that attributions for the participants’ actions will depend on positive and negative evaluations of their intentions and behaviors. We describe empirical findings that are consistent with this assumption, and predict other findings for causal deviance phenomena that have not yet been investigated empirically. (shrink)

“How can I, who am thinking about the entire, centerless universe, be anything so specific as this: this measly creature existing in a tiny morsel of space and time?” This metaphysically self-deprecating question, posed by Thomas Nagel, holds an insight into the nature of personhood and the ordinary ways we value it, in others and in ourselves. I articulate that insight and apply it to the phenomena of friendship, companionship, sexuality, solitude, and love. Although love comes in many forms, I (...) say, it always involves a sense of wonder at a finite creature thinking infinite thoughts. (shrink)

"The first of the particular arts . . . is architecture." (A 13.116/1.83)1 For Hegel, architecture stands at several beginnings. It is the art closest to raw nature. It is the beginning art in a progressive spiritualization that will culminate in poetry and music. The drive for art is spirit's drive to become fully itself by encountering itself; art makes spirit's essential reality present as an outer sensible work of its own powers.2 (A 13.453/1.351) If Hegel's narrative of the arts (...) creates a hierarchy, architecture stands lowest, yet it nonetheless plays a unique and necessary role in spirit's development. In this essay I first describe Hegel's views on the nature of architecture and its three stages (symbolic, classical, romantic). Then I indicate some problems with Hegel's narrative. Finally I raise the question whether Hegel's theories might be adapted to our present architectural situation. (shrink)

Instead of the half-century old foundational feud between set theory and category theory, this paper argues that they are theories about two different complementary types of universals. The set-theoretic antinomies forced naïve set theory to be reformulated using some iterative notion of a set so that a set would always have higher type or rank than its members. Then the universal u_{F}={x|F(x)} for a property F() could never be self-predicative in the sense of u_{F}∈u_{F}. But the mathematical theory of categories, (...) dating from the mid-twentieth century, includes a theory of always-self-predicative universals--which can be seen as forming the "other bookend" to the never-self-predicative universals of set theory. The self-predicative universals of category theory show that the problem in the antinomies was not self-predication per se, but negated self-predication. They also provide a model (in the Platonic Heaven of mathematics) for the self-predicative strand of Plato's Theory of Forms as well as for the idea of a "concrete universal" in Hegel and similar ideas of paradigmatic exemplars in ordinary thought.

Dual-role approaches to reasons say, roughly, that reasons can relate to actions in two fundamentally different ways: they can either require conformity, or justify an action without requiring that it be taken. This paper develops a formal dual-role approach, combining ideas from defeasible logic and practical philosophy. It then uses the approach to shed light on the phenomenon of supererogation and resolve a well-known puzzle about supererogation, namely, Horton’s All or Nothing Problem.

Sometimes, art theory addresses the same type of image from discursive disparity. This is the case of the portrait, whose imprecise definition complicates its conceptual and formal definition within the limits of the Western culture.

A discussion of the problem of creating unified places in a pluralistic multicultural society.

When I was first studying Hegel I encountered quite divergent readings of his views on religion. The teacher who first presented Hegel to me was a Jesuit, Quentin Lauer at Fordham University, who read Hegel as a Christian theologian providing a better metaphysical system for understanding the doctrines of the Trinity and Incarnation. When I studied at Yale, Kenley Dove read Hegel as the first thoroughly atheistic philosopher, who presented the conditions of thought without reference to any foundational absolute being. (...) Meanwhile, also at Yale, John Findlay read us a deeply Neo-Platonic Hegel who taught about absolute forms held in a cosmic mind. In giving my own reading I want to talk about the ways Hegel redefines both metaphysics and religion. I would like to approach these issues by way of the medieval controversy over double truth, which was a previous conflict between religion and science. (shrink)

I am a philosopher with Parkinson’s Disease. Over the past several years I’ve been trying to write about my situation. I wrote about how I was forced to face the disease. I described how the disease twists and distorts my world. Then I asked myself, as a philosophy writer and teacher, whether I could say anything that might help myself or others facing life with Parkinson’s? I found ideas in the ancient Stoics and expanded them with ideas about time, coming (...) up with suggestions for living as excellently as possible despite the disease. Looking at those suggestions, I realized how the special awareness, resolve, and attention I was suggesting would be eaten away by dementia, and I know that a majority of Parkinson’s patients face dementia if they survive long enough.

Writing about such issues has helped me deal with my situation, and maybe my essay might be useful for others dealing with decline. (shrink)

A critical examination of the different kinds of irony relevant to architecture, especially romantic and postmodern irony, and a suggestion for a less self-sure haughty kind of irony.

One of the most difficult issues to sort out morally is our obligation to future generations. Most individuals feel that they do indeed have some kind of obligation, but face difficulty in explaining the exact nature of the obligation. For one, it seems impossible to know the wants and desires of future generations, and furthermore the existence of the persons we are obligated to is entirely dependent upon the choices that we in fact make. In essence, we could shape future (...) generations so that they desire exactly what we provide for them. It seems that no matter what principle we adopt that is based upon these potential individuals we are led to absurd conclusions. Gregory Kavka calls this moral grappling the Paradox of Future Individuals. I believe that the ethical concerns surrounding genetic engineering should be seen as a specific instantiation of this Paradox and that by examining both we may be able to come up with some sort of working solution. Derek Parfit pleads ignorance as to a solution to this Paradox after an extensive exegesis on the issue, but as we may not be that far from shopping a genetic supermarket to determine the characteristics of our children I don’t believe we can settle for that conclusion. We will begin by examining the Paradox and suggested solutions to the Paradox. Next I will address how the Paradox relates directly to genetic engineering and discuss how rights-based arguments aimed against genetic engineering fail because of the nature of identity. Then I will consider how David Heyd’s Genero-centric principle applies to genetic engineering specifically and how a modified version of that principle may guide us out of the Paradox of Future Individuals in general. This solution may not be acceptable to utilitarian sensibilities, but it is because the numbers don’t add up that we may need to appeal to a different principle entirely. (shrink)

Galileo’s telescopic lunar observations, announced in Siderius Nuncius (1610), were a triumph of observational skill and ingenuity. Yet, unlike the Medicean stars, Galileo’s lunar “discoveries” were not especially novel. Indeed, Plutarch had noted the moon’s uneven surface in classical times, and many other renaissance observers had also turned their gaze moonward, even (in Harriot’s case) aided by telescopes of their own. Moreover, what Galileo and his contemporaries saw was colored by the assumptions they already had. Copernicans assumed the moon was (...) a terrestrial satellite, thus Galileo saw its mountains and Kepler “saw” the dwellings of its inhabitants. Aristotelians assumed the moon was a perfect sphere, so they saw differences in density and rarity in the lunar body. Theory corrected the results of observation, so Galileo’s lunar observations, like those that had come before, proved nothing. Yet this failure contained the germ of Galileo’s success, since the Siderius Nuncius gave observation a rhetorical force it did not have before. Observers on all sides set out to see for themselves what Galileo reported. Hence, all parties now had to answer to what they saw, whatever they believed. Thus, the Siderius Nuncius ultimately changed the grounds upon which natural philosophical argument and debate was carried out. In this new empirical arena, the Galilean science would eventually prevail. (shrink)
