In the paper, after clarifying terms such as ‘identity’, ‘self’ and ‘personhood’, I propose an empirical account of identity based on the notion of “whole phenotype”. This move allows one to claim the persistence of the individuals before and after their being affected by dementia. Furthermore, I show how this account permits us to address significant questions related to demented individuals’ loss of the capacity of moral decisions.

A dogma of contemporary normative theorizing holds that some reasons are distinctively moral while others are not. Call this view Reasons Pluralism. This essay looks at four approaches to vindicating the apparent distinction between moral and non-moral reasons. In the end, however, all are found wanting. Though not dispositive, the failure of these approaches supplies strong evidence that the dogma of Reasons Pluralism is ill-founded.

How should an agent decide what to do when she is uncertain not just about morally relevant empirical matters, like the consequences of some course of action, but about the basic principles of morality itself? This question has only recently been taken up in a systematic way by philosophers. Advocates of moral hedging claim that an agent should weigh the reasons put forward by each moral theory in which she has positive credence, considering both the likelihood that that theory is (...) true and the strength of the reasons it posits. The view that it is sometimes rational to hedge for one's moral uncertainties, however, has recently come under attack both from those who believe that an agent should always be guided by the dictates of the single moral theory she deems most probable and from those who believe that an agent's moral beliefs are simply irrelevant to what she ought to do. Among the many objections to hedging that have been pressed in the recent literature is the worry that there is no non-arbitrary way of making the intertheoretic comparisons of moral value necessary to aggregate the value assignments of rival moral theories into a single ranking of an agent's options. -/- This dissertation has two principal objectives: First, I argue that, contra these recent objections, an agent's moral beliefs and uncertainties are relevant to what she rationally ought to do, and more particularly, that agents are at least sometimes rationally required to hedge for their moral uncertainties. My principal argument for these claims appeals to the enkratic conception of rationality, according to which the requirements of practical rationality derive from an agent's beliefs about the objective, desire-independent value or choiceworthiness of her options. Second, I outline a new general theory of rational choice under moral uncertainty. Central to this theory is the idea of content-based aggregation, that the principles according to which an agent should compare and aggregate rival moral theories are grounded in the content of those theories themselves, including not only their value assignments but also the metaethical and other non-surface-level propositions that underlie, justify, or explain those value assignments.

Starting from the sensuous perception of what is seen, an attempt is made at re-casting a Husserlian theory of constitution of the object of intuition, as one leaves the natural attitude through a transcendental method, by positing several theses so as to avoid the aporias of philosophical binary oppositions such as rationalism and empiri-cism, realism and idealism, logicism and psychologism, subjectivism and objectivism, transcendentalism and ontologism, metaphysics and positivism. Throughout fifty-five theses on constitution, the Husserlian proposal of continuously reforming philosophizing (...) by transcendental reduction is revisited, leaving the latter incomplete as new conversions are required by noetic-noematic correlations between world and consciousness.

The idea that people’s numerical identity may sometimes be discontinuous over time initially appears to provide useful material for defending restrictions on putatively self-harming behaviour in a non-paternalistic manner. According to this line of thinking, sometimes a putatively self-harming act is, in fact, a matter of ‘harm to others’. Yet, in this paper I argue that if we, as we ought to do, take into consideration the non-identity problem, this challenges the notion that the agent at T1 is in fact (...) imposing harm on anyone, even when we accept that he or she is numerically different from the agent at T2. If the life of the agent at T2 is still worth living, the agent is not worse off than he or she would have been in spite of the consequences pertaining to the putatively self-harming act since he or she would otherwise never have come into existence. In this way, the argument I put forward in this paper calls in question the ability of the shifting identity argument to actually justify imposing restrictions on self-harming behaviour. (shrink)

The increasing number of dementia cases has led to renewed interest in philosophical theories of personal identity, because these patients seem to “drop out” of their own identities in some ways. Philosophical positions that try to account for the phenomenon of identity loss include numerical theories of identity which argue for a psychological or a biological continuity criterion, narrative theories of identity, as well as reflections about different forms of memory, some of which have had influence in modern psychology and (...) in the neurosciences. This special issue brings together current articles by experts in these areas. / Die zunehmende Verbreitung von Demenzerkrankungen hat zu einem erhöhten Interesse an philosophischen Theorien der personalen Identität geführt, da diese Patienten in manchen Hinsichten aus ihrer eigenen Identität „herauszufallen“ scheinen. Zu den philosophischen Ansätzen, die sich hiermit beschäftigen, gehören Theorien der numerischen Identität, wie etwa das psychologische oder das biologische Kontinuitätskriterium, narrative Theorien der Identität, aber auch Refl exionen über verschiedene Formen des Erinnerns, die sich zum Teil in der modernen Psychologie und in den Neurowissenschaften niederschlagen. Dieses Schwerpunktheft enthält aktuelle Beiträge von Experten aus den genannten Bereichen. ​The increasing number of dementia cases has led to renewed interest in philosophical theories of personal identity, because these patients seem to “drop out” of their own identities in some ways.

On 25 April 2002, the German Parliament has passed a strict new law referring to stem cell research. This law took effect on July 1, 2002. The so-called embryonic Stem Cell Act ( Stammzellgesetz — StZG ) permits the import of embryonic stem (ES) cells isolated from surplus IvF-embryos for research reasons. The production itself of ES cells from human blastocysts has been prohibited by the German Embryo Protection Act of 1990, with the exception of the use of ES cells (...) which exist already. The debate on the legitimate use of ES cells escalated, after the main German research funding agency, the Deutsche Forschungsgemeinschaft (DFG), unexpectedly published new guidelines recommending are stricted use of human ES cells for research. Meanwhile, the debate has ethically dividedsociety, political parties, government and church members into a group supporting and a group rejecting ES cell research. The arguments in favour of such a research can be summarized as arguments derived from a new ethics ofhealing calling for a therapeutic imperative, whereas the arguments against can be summarized as arguments violating the fundamental principle of human dignity as they imply the destruction of human embryos. This article willtry to present and evaluate various ethical arguments founded on the latest biological and medical data on the potential use of stem cell technologies. It will finally come to the conclusion that ES cell research is opposed to human dignity, since the procedures of isolating ES cells require the destruction and instrumentalization of human embryos. Human embryos are human beings at a very early stage of their development, fully possessing the ability of completing their development. At this very early stage, human embryos are extremely dependent and fragile, and thus vulnerable corporealities. Vulnerability and human dignity demand the protection of the embryo's corporeal integrity. Hence, this essay will try to propagate research with adult stem(AS) cells, a procedure which does not require the destruction of human embryos; with regard to the necessary plasticity, it should be emphasized that AS cells very much resemble ES cells.

Empirical findings suggest that temptation causes agents not only to change their desires, but also to revise their beliefs, in ways that are not necessarily irrational. But if this is so, how can it be rational to maintain a resolution to resist? For in maintaining a resolution it appears that one will be acting against what one now believes to be best. This paper proposes a two-tier account according to which it can be rational neither to reconsider the question of (...) what one is going to do nor the question of what it is best to do; hence in the resolute agent the change in belief is not actual but merely potential. Various reasons are given for thinking that the resulting account is preferable to an alternative given by Bratman. (shrink)

You and I lead different lives. While we share a society and a world, our existence is separate from one another. You and I matter individually, by ourselves. My dissertation is about this simple thought. I argue that this simple insight, the separateness of persons, tells us something fundamental about morality. My dissertation seeks to answer how the separateness of persons matters. I develop a precise view of the demands of the separateness of persons. The separateness of persons imposes both (...) a requirement on the justification of first-order moral principles as well as a requirement on the content of first-order moral principles. In specifying these demands, I argue that respecting the separateness of persons requires taking into consideration each person’s point of view separately. This requires taking into account the moral relations in which individuals stand to one another. I make use of this relational understanding of the separateness of persons to advance various debates in moral and political philosophy. I argue for a framework to assess to which extent the veil of ignorance can be reconciled with the separateness of persons. I also argue for a new view on the ethics of risk which is a form of contractualism that discounts risks only by their objective risk. Furthermore, I argue for a new solution to the problem of aggregation that is skeptical of aggregation and can set plausible limits to aggregation. Lastly, I provide a new relational agent-based justification for deontological constraints. In addition to answering how the separateness of persons matters, I defend the separateness of persons against challenges. Most importantly, I argue that the importance of the separateness of persons is not undermined even if we believe that our personal identity, i.e. whether we persist as the same person, is unimportant.

Some propositions are structurally unknowable for certain agents. Let me call them ‘Moorean propositions’. The structural unknowability of Moorean propositions is normally taken to pave the way towards proving a familiar paradox from epistemic logic—the so-called ‘Knowability Paradox’, or ‘Fitch’s Paradox’—which purports to show that if all truths are knowable, then all truths are in fact known. The present paper explores how to translate Moorean statements into a probabilistic language. A successful translation should enable us to derive a version of (...) Fitch’s Paradox in a probabilistic setting. I offer a suitable schematic form for probabilistic Moorean propositions, as well as a concomitant proof of a probabilistic Knowability Paradox. Moreover, I argue that traditional candidates to play the role of probabilistic Moorean propositions will not do. In particular, we can show that violations of the so-called ‘Reflection Principle’ in probability need not yield structurally unknowable propositions. Among other things, this should lead us to question whether violating the Reflection Principle actually amounts to a clear case of epistemic irrationality, as it is often assumed. This result challenges the importance of the principle as a tool to assess both synchronic and diachronic rationality—a topic which is largely independent of Fitch’s Paradox—from a somewhat unexpected source.

Multiple self approaches purport that to have equal concern about all stages of one’s life is not a requirement of rationality. This poses a challenge to the prudential lifespan account which Norman Daniels advocates in Just health: meeting health needs fairly. Daniels has criticised the multiple self approach in earlier works, most extensively in Am I my parents keeper? In Just health, he only takes up the issue except in one footnote, presumably because he is convinced that his preceding discussions (...) settled the matter. This article argues that Daniels underestimates the force of the multiple self objection to prudential lifespan account. (shrink)

The relation of our past memories and our communication with others is not simply that of linear causality, whereby our memories smoothly glide into our communicative performance and remain unaffected themselves. Psychologists reveal the opposite process where a current communication has an effect on our memories, not just influencing their selection but also producing false recognition. In this article I will attempt to give a philosophical evaluation of this twofold relationship of memory and communication, paying a special attention to the (...) fabrication of memories, to the significance of this process for the effectiveness of social integration, and to the effects it may have on our authenticity as individuals.An act of communication is not a creation ex nihilo but is a culmination of numberless physical and psychological processes, one of which is remembering, forgetting and recalling. What we say ourselves may be a logical and smooth prolongation of our memories and our past lives, but what we hear from others is not. The information that is communicated to us may contradict our previous beliefs, our previous understanding of the matter in question, and even threaten our established worldview. This is acutely felt by people who have to live through a value-changing period in their society or through a crisis in their personal life.Nevertheless we are required to maintain the communicative process and respond to new demands, and so we have to find ways of adapting ourselves to the new information, even if our past experiences and beliefs cannot serve as a foundation for accepting it. We can, however, construct such a foundation retrospectively, making ourselves believe that we were being prepared for this new situation. For example, the people who lived through the collapse of the Soviet Union, had to face a complete change of values, and the process of adaptation seemed less traumatic for those who, fabricated or inflated their own supposed disagreement with the system prior to the political changes.

Following Hardin’s paper of “The tragedy of the commons”, it has been traditionally sustained that the government should manage public good resources since their private management would lead to their depletion. However, Elinor Ostrom has challenged this account by identifying a specific type of Common-pool resources that, under circumstances of trust and fluid communication between the parties involved, can be efficiently managed by groups of individuals. In this context, it is this paper’s contention that the postulates of deliberative democracy are (...) compatible with an efficient management of common-pool resources. Thus, this finding would contradict literature that autocratic governments are more effective in managing natural resources. (shrink)
