Disgust is often believed to have no special moral relevance. However, there are situations where disgust and similar feelings like revulsion, repugnance, or abhorrence function as the expression of a very strong moral disapproval that cannot fully be captured by argument. I call this kind of disgust moral disgust.Although it is always in principle possible to justify our moral disgust by explaining what it is in a given situation or action that disgusts us, the feeling of disgust often comes first and either draws our attention to the fact that there is something wrong in the first place, or makes us aware that the kind of wrongness we are dealing with surpasses what can be accounted for by established moral theory. In both cases moral disgust serves an important purpose for an adequate moral evaluation of diverse situations and the actions from which they result

This paper argues that the goal the proponents of radical life extension wish to attain is in fact unattainable, and that with regard to this goal, the whole project of conquering ageing and death is therefore likely to fail. What we seek to achieve is not the prolongation of life as such, but rather the prolongation of a healthy and youthful life. Yet even though it may one day be possible to prevent the body from ageing beyond a certain stage , it may never be possible to arrest the ageing of the mind, which is what we desire most of all

Nicholas Agar argues that it is possible, and even likely, that radically enhanced human beings will turn out to be ‘post-persons’, that is, beings with a moral status higher than that of mere persons such as us.1 This would mean that they will be morally justified in sacrificing our lives and well-being not merely in cases of emergency, but also in cases of ‘supreme opportunities’ , that is, whenever such a sacrifice leads to ‘significant benefits for post-persons’. For this reason, Agar believes, it would be morally wrong to allow any cognitive enhancement of people that might entail the risk of moral status enhancement.However, neither are there sufficient grounds to expect radically enhanced human beings to have a higher moral status than unenhanced human beings, nor would it, even if they did, be morally wrong to bring about their existence. We use moral status ascriptions mostly as a convenient shorthand to indicate a difference in capacities that strikes us as morally relevant. Rocks have zero moral status because they cannot feel or think, so we cannot hurt or kill them. Whatever we do to them, it does not affect them. Animals, on the other hand, …

After showing that despite being inherently flawed the concept of dignity cannot be replaced without loss by ethical principles such as “respect for persons,” it is argued that, if dignity be not understood as dignitas, but as bonitas, which emphasizes connectedness rather than excellence and to which the proper response is not respect, but awe, there is no reason not to ascribe it to the human embryo. The question whether or not human embryos have dignity can then be answered in the affirmative on the same pragmatist grounds that ultimately lead us to respect other human persons as possessors of dignity, that is, a special moral worth

I argue that Mill introduced the distinction between quality and quantity of pleasures in order to fend off the then common charge that utilitarianism is ‘a philosophy for swine’ and to accommodate the (still) widespread intuition that the life of a human is better, in the sense of being intrinsically more valuable, than the life of an animal. I argue that in this he fails because in order to do successfully he would have to show not only that the life of a human is preferable to that of an animal on hedonistic grounds, but also that it is in some sense nobler or more dignified to be a human, which he cannot do without tacitly presupposing non-hedonistic standards of what it means to lead a good life.

Genetic engineering is often looked upon with disfavour on the grounds that it involves "tampering with nature". Most philosophers do not take this notion seriously. However, some do. Those who do tend to understand nature in an Aristotelian sense, as the essence or form which is the final end or telos for the sake of which individual organisms live, and which also explains why they are as they are. But is this really a tenable idea? In order to secure its usage in present day ethics, I will first analyze the contexts in which it is applied today, then discuss the notion of telos as it was employed by Aristotle himself, and finally debate its merits and defend it, as far as possible, against common objections.

Michael Sandel's opposition to the project of human enhancement is based on an argument that centres on the notion of giftedness. Sandel claims that by trying to ?make better people? we fall prey to, and encourage, an attitude of mastery and thus lose, or diminish, our appreciation of the giftedness of life. Sandel's position and the underlying argument have been much criticised. In this paper I will try to make sense of Sandel's reasoning and give an account of giftedness that defends its relevance for the ethical assessment of the human enhancement project. In order to do so, I will also look at virtue-related notions, such as gratitude and humility, and distinguish the gifted from the merely given. The failure to acknowledge this distinction gives rise to one of the most common objections to Sandel's argument. Other objections will be shown to rest on similar misunderstandings

Sorgner (2009, 29) has argued that Bostrom (2005, 4) was wrong to maintain that there are only surface-level similarities between Nietzsche’s vision of the overman, or overhuman, and the transhumanist conception of the posthuman. Rather, he claims, the similarities are “significant” and can be found “on a fundamental level”. However, I think that Bostrom was in fact quite right to dismiss Nietzsche as a major inspiration for transhumanism. There may be some common ground, but there are also essential differences, some of which I am going to point out in this brief reply.
