1 The Moral Status of Artificial Life Bernard Baertschi, Institute for Biomedical Ethics, University of Geneva Abstract Recently at the J. Craig Venter Institute, a microorganism has been created through synthetic biology. In the future, more complex living beings will very probably be produced. In our natural environment, we live amongst a whole variety of beings. Some of them have moral status – they have a moral importance and we cannot treat them in just any way we please –; some do not. When it becomes possible to create artificially living beings who naturally possess moral status, will this artificiality modify their status? Many people contend that it will, but I am not of the same mind and will develop three arguments against it. Key words: moral status, intrinsic value, artificial life, moral responsibility Introduction Since the beginning of the 21st century, ethical reflection on synthetic biology has been growing, due to the advances in this field. This reflection targets mainly three aspects: potential dangers for human beings (biosafety and biosecurity) versus potential benefits, justice and fairness, and the moral stance adopted by human beings concerning life (playing God and hubris) (Presidential Commission, 2010; Deutsche Forschungsgemeinschaft, 2009). It is easy to understand the reasons for these concerns. Firstly, beings created by synthetic biology are microorganisms, and some microorganisms are very dangerous for our health. 2 They may be dangerous for our environment, too. Secondly, present day biotechnologies are expensive and their fruits will probably be more accessible to affluent citizens in affluent countries. Thirdly, creation of life has been the prerogative of divine entities in our tradition, therefore there is some worry that human beings could try to adopt a demiurgic stance. Contrasting two ways of producing artificial living beings, one consisting in modifying existing beings, and another consisting in building them from inanimate molecules, Joachim Boldt and Oliver Müller speak in a theological manner of ‘creation ex existendo’ and ‘creation ex nihilo’ (2008: 388). These moral concerns are aimed at human beings and their environment, but they overlook another one, pertaining to the attitude we ought to adopt towards created artificial beings themselves. This attitude relies on several factors, a prominent one of which is moral status. In this paper, I will examine this topic and try to answer the question of the moral status of artificial life, that is, the moral status of individual living beings, since in our tradition, only individual entities are generally deemed to possess moral status. It is nevertheless a debated topic, if collective entities like ecosystems can possess moral status, but this question must not hold us back, because artificial life is not a collective, it is an abstract entity. The question of artificial living beings’ moral status has not been much debated yet, and it is easy to understand why: the only beings artificially produced till now have been microorganisms, and the moral status of microorganisms is not a very pressing topic – perhaps it is even a spurious one. Nevertheless, it seems to me that there exist two good reasons to examine this question. The first is that some philosophers and ethicists adopt a biocentrist position, that is, a position that grants moral value to every living being. The second is that it will perhaps be possible in some future to create living beings that are much more complex; certain authors even hope to re-create members of some extinct species (ETC Group 2007: 38). In a sense, such artificial complex beings already exist: think of animal 3 clones or of babies born after IVF. Of course, it depends on how you understand ‘artificial’. After the J. Craig Venter Institute successfully transplanted the Mycoplasma micoides genome in Mycoplama capricolum in March 2010, Roberta Kwok said that ‘the team has fielded criticism for calling the resulting cell “synthetic” when the genome was essentially a replica of a natural genome and required an existing recipient cell. Hutchison argues that ‘synthetic simply means “chemically synthesized”, not newly designed.’ (2010: 25). Like ‘artificial’, ‘synthetic’ has several meanings, even if we restrict its scope to the domain of synthetic biology. Dieter Birnbacher has distinguished two important meanings of ‘artificial’ (1006: 8). It can be used in a genetic sense and in a qualitative sense. In the first sense, ‘artificial’ means ‘produced by human beings’. As we can see, it is an historical sense: we are describing the history of a being’s production; if a human being is the main contributor to it, the being is artificial, otherwise, it is natural. As human beings have hugely impacted nature, there are some problems of scope with this definition; for this reason I will add: ‘produced by human beings and by contemporary technological means’. In the second sense, ‘artificial’ means ‘similar to what is natural’. This sense is not historical, but phenomenological: if an artificial being has properties similar to a natural one, then it is natural in the qualitative sense. It follows that a being can be artificial in the genetic sense and natural in the qualitative one. This is for a large part the case with Mycoplama micoides/capricolum created at the J. Craig Venter Institute. In this paper, I will focus on the genetic sense, but not exclusively, and will proceed in the following manner. Firstly, I will clarify the meaning of ‘moral status’ with reference to natural beings, i.e., beings we find in our environment like adult human beings and animals. Of course, many of those beings have been transformed and manipulated in our hands, but largely with the use of non-technological methods (natural breeding, cross-fertilisation, education …). Secondly, I will collect some claims saying that the difference between being a product of nature (i.e. 4 being natural) and being a product of human technology (i.e. being artificial) has, directly or indirectly, moral relevance for moral status. Thirdly, I will develop three arguments, one conceptual, one ontological, and one based on analogy to show that this belief is a mistake. I will conclude with a proposal, inspired by Dworkin, to consider the moral impact of the distinction natural/artificial in another light. The Concept of ‘Moral Status’ Mary Anne Warren states: ‘To have moral status is to be morally considerable, or to have moral standing. It is to be an entity towards which moral agents have, or can have, moral obligations. If an entity has moral status, then we may not treat it in just any way we please’ (1997: 3). Beings that possess moral status have moral relevance or importance; some of them possess rights. But who has moral importance? There is much disagreement on this point. For some, called anthropocentrists, only human beings possess moral status; for others, called pathocentrists, every being able to feel pleasure and pain has moral importance; for others, called biocentrists, every living being is morally considerable (ECNH, 2010: 15-17). An old kind of biocentrism attributes such a status to all living beings, but in an ordered way: there exists a hierarchy or a scale of beings, with plants at the bottom and human beings (or God) at the top. This seems to be old-fashioned, but it is still widely held, for instance in animal experimentation, when it is claimed that it is less objectionable to sacrifice a mouse than a chimpanzee, an assertion made, for instance, by the Nuffield Council (1996: 51). To date, we have created only microorganisms. Therefore, if you are not a biocentrist or someone who confers some moral value on such low creatures, the question that I have asked will receive a very quick answer: artificial living beings have no moral status, they are beings we can treat any way we please. But, as I have said, this quick answer is not satisfying, because synthetic biology will progress. It is not satisfying for another reason too: if you are 5 not a biocentrist, artificial microorganisms do not possess any moral status, but natural ones are on the same footing. Therefore the quick answer prevents every attempt to evaluate the impact of artificiality on moral status. And it is exactly this question that is of interest. In order to be able to determine if artificiality has an impact on moral status, I must analyse more deeply what moral status consists of, independently of the question concerning the kind of beings that possess or do not possess it. To illustrate my analysis, I will use examples of beings that possess or could reasonably be said to possess such a status, but it will only be for the purpose of being clearer. Anthropocentrists, pathocentrists and biocentrists diverge, but what reason do they have in favour of their positions? When we ask them: ‘Why do you grant moral status to X’, they point to some property of X. For example: ‘Human beings have moral status because they are rational beings’, or ‘Animals are morally considerable because they are sentient (i.e. they can feel pleasure and suffer)’. ‘To be rational’ or ‘to be sentient’ are properties conferring moral status. But how and why? What is the nature of these properties and why are they capable of conferring moral status? What is the nature of these properties? They are intrinsic properties. An intrinsic property, says Warren, is a property a being possesses independently of its environment: ‘A thing’s intrinsic properties are those which it is logically possible for it to have had were it the only thing in existence’ (1997: 21). Intrinsic properties are contrasted with extrinsic properties, that is, with properties a being possesses because of its environment. The two main kinds of extrinsic properties are relational ones and instrumental ones. A human being possesses intrinsic properties (e.g., reason), relational ones (e.g., he is loved), and instrumental ones (e.g., he is a waiter). If we have some hesitation about categorising a property (think of ‘to be blue’: is it intrinsic or relational?), a syntactic test will give the right answer: intrinsic properties are monadic, i.e. they have only one place free, whereas extrinsic 6 ones are polyadic, i.e. they have more than one place free: F(x) is intrinsic, F(x,y) is extrinsic (Bochenski, 1959: 43 and 51). Therefore ‘to be blue’ is intrinsic and ‘to be bluer than’ is extrinsic (relational). But I will not dwell on this logical point, even if it has some importance, as we will see. For now, let us admit that moral status is conferred by intrinsic properties and not by extrinsic onesi. How do such properties confer moral status? Not all intrinsic properties confer moral status; they must also be valuable. Some properties ground values; intrinsic properties ground intrinsic value, and external properties external values. Following G. E. Moore, we can say that a being’s intrinsic value is the value he possesses by virtue of his intrinsic (or internal) properties (Rabinowicz and Rønnow-Rasmussen, 2000: 33; Baertschi, 2009, chap. 2.1). Technically, we say that values supervene on properties. Stripped of modern jargon, this thesis is very old. Take ‘dignity’, a concept long used to characterise the intrinsic value of entities like human beings. We read in Aquinas’ Commentary on the Sentences this passage: ‘Dignity means the goodness something possesses because of itself, utility its goodness because of another’ [dignitas significat bonitatem alicujus propter seipsum, utilitas vero propter aliud] (lib. 3, d. 35, q. 1, a. 4, q. 1, c). In contemporary words: dignity means the intrinsic value something possesses by virtue of some intrinsic or internal properties, utility its instrumental value by virtue of some extrinsic or external properties. Kant agrees on this point: ‘In the realm of ends everything has either a price or an intrinsic value [Würde]. Anything with a price can be replaced by something else as its equivalent, whereas anything that is above all price and therefore admits of no equivalent has intrinsic value’ (2008: 33). Bennett translates ‘dignity’ by ‘intrinsic value’, because, as he says in a footnote: ‘At the end of the next paragraph Kant explicitly equates those two meanings, when he speaks of ‘intrinsic value’ (i.e dignity) [einen innern Wert, d.i. Würde]’. To summarise: a being possesses moral status if he has a peculiar value grounded in 7 some of his intrinsic properties. Extrinsic properties can also ground value, but they are not constitutive of moral status. Why? Tristram Engelhardt says: ‘The fetus of a woman who wants a child takes on considerable significance. It gains value from her interests and love, and that of others around her. The would-be mother, father, grandmothers, grandfathers, uncles, and aunts can vest a wanted embryo or fetus with great value. The opposite can obtain as well. Because of the circumstances of the conception, the probable circumstances of the birth, or because the fetus is defective or deformed, a negative worth may be given. The fetus may be seen as something that is threatening, harmful, disvalued, or even hated’ (1986: 218). The value a foetus possesses is twofold: on the one hand, he has relational value or disvalue, because of the attitude of his parents and family; on the other hand, he has intrinsic value because he is a human being. The last point is contested, but let us admit that a foetus has intrinsic value like any other human being. In this case, the foetus’ moral status depends entirely on what he is, i.e., on his intrinsic properties. If this were not the case, if his status were dependent on his relationships or on his utility, his status would vary accordingly. This may not be shocking when you think of a foetus, but think of an adult: his moral status must be independent of his personal, social and political relations. Take human rights: they are based on the possession of humanity only. It is interesting to note that some authors object to the exclusion of extrinsic values from consideration of moral status when the moral status of ‘low’ entities is in question. Warren claims that, for beings like embryos and foetuses: ‘The criteria of moral status must include both certain intrinsic properties, including life, sentience, and personhood; and certain relational properties, which sometimes include being part of a particular social […] community’ (1997: 21). Baertschi and Mauron maintain the same position for embryos, because they are essentially entities in becoming, that is, entities whose development demands a heavy contribution from their environment, natural and social (2010: 102). 8 Moreover, if moral status encompasses all reasons to value an entity, as Warren’s definition could suggest, relational values would find an important place within it. Or course, embryos and foetuses are rather peculiar entities, but artificial living beings like microorganisms are ‘low’ entities too, and even very low ones; therefore extrinsic value could perhaps be relevant in their cases. This consideration has some importance for me, because, if accepted, the inclusion of extrinsic value in moral status would partly undermine the conceptual argument I will propose. However, for the moment, I will put this last point aside, and will apply the moral status scheme developed so far to artificial living beings. I will say that when an artificial being has a moral status, it is a function of its intrinsic value, grounded in some of its intrinsic propertiesii. Accordingly, the question to be asked is the following: if a being is created by human modern technology rather than by nature, does it change its moral status, that is, its intrinsic value, or not? The Demeaning Effect of Human Hands Many people think that it does, and for the worse. Frequently, we hear claims about the goodness of what is natural and the badness of what is synthetic, chemical or artificial. Such claims are in general not voiced in relation to status, but with agency. Nature does good, but human beings do not. Since ‘artificial’ denotes a mode of production and its product, the negative evaluation associated with the first contaminates the second. The debates concerning medicine (classical versus natural), GMO versus “naturally” grown plants iii , and more generally biotechnologies are full of such claims. In a study concerning genetic engineering, Rob De Vries states that, in the Netherlands, 57% of the respondents think that this biotechnology is non-natural, and consider that it constitutes a problem; and these respondents were not lay people, but people involved in biomedical science (2006: 218-220). More 9 generally, Henry Miller says that ‘in the case of the new biotechnology in the United States today, the myth is of a childlike, “natural” world of purity and innocence that is corrupted by scientific advances, especially those that “tamper with Nature”’ (1996: 98). In this context, it is not surprising that many scientists fear that the use of the word ‘synthetic’ in synthetic biology will be associated by the public with ‘negative images of monstrous life forms let loose by maniacal scientists’ (Balmer and Martin, 2008: 6). It is a job for sociologists and historians to investigate the roots and motives for such beliefs – I will nevertheless come back to this subject in my conclusion –, but they are widely spread in our society, and can be put under the banner of Jean-Jacques Rousseau, asserting in Émile, in a style reminiscent of original sin: ‘God makes all things good; man meddles with them and they become evil. He forces one soil to yield the products of another, one tree to bear another’s fruit. He confuses and confounds time, place, and natural conditions. He mutilates his dog, his horse, and his slave. He destroys and defaces all things; he loves all that is deformed and monstrous; he will have nothing as nature made it, not even man himself, who must learn his paces like a saddle-horde, and be shaped to his master’s taste like the trees in his garden.’ (2007: 6) For people who entertain ideas like these, there is a short way to consider that what human beings create is not on the same footing as what nature creates. Some of them will claim that the products of human hands and their natural counterparts are dissimilar, that there exists an ontological difference between them, i.e., that their intrinsic properties are not identical, even if they seem to be. For instance, synthetic vitamin C and natural vitamin C are chemically different for them and have different effects on our body (synthetic vitamin C is seemingly qualitatively natural, but it is a sham). Others will not be so precise and will only contend that synthetic vitamin C is changed in some way, probably harmful to us. Think also of the GMO debate, where a process of production is deemed to be in itself damaging and 10 denaturing. As we can see, the link with moral status could easily be drawn from such considerations, even if it is very seldom articulated. In the case where X has a moral status, it implies that its moral status is different, due to the fact that it is naturally or artificially created. According to the demeaning effect of human hands, it would even be possible that an artificial X loses its moral status as an X. It is important to distinguish the above considerations from the reflections of Jürgen Habermas when he says: ‘My particular concern is with the question of how the biotechnological dedifferentiation of the habitual distinction between the “grown” and the “made”, the subjective and the objective, may change our ethical self-understanding as members of the species’ (2003: 23). Biotechnologies move the line separating the natural (what is grown) and the artificial (what is made), and this has an impact on the way we perceive ourselves. Like Rousseau, Habermas is not very optimistic on this point – he is not very far from the American conservatives Kass and Sandel –, but his argument has nothing to do with ontology (intrinsic properties) and moral status, it has nothing to do with what is and could be created by us: it pertains to the question of the image human beings create of themselves and the role they ought to play in nature and in society. I will return to this point in my conclusion. Three Arguments Is this belief – i.e. the belief that an X has a different moral status, depending on whether it is naturally or artificially created – correct? I think it is not, and I will give three arguments, one conceptual, one ontological, and one based on analogy to show that it is a mistake. The third argument, based on analogy, is perhaps conceptually less cogent, but psychologically much more striking. The conceptual argument relies on the concept of moral status as a function of intrinsic 11 properties. It is very simple: 1. The moral status of a being depends on what it is, i.e., on its intrinsic properties. 2. ‘To be created’ is not an intrinsic property, but an extrinsic one. More precisely, it is a relational one, since ‘to be created’ is a dyadic property (a two places property) stating a relation: ‘—is created by—‘ 3. Therefore ‘to be created’ has nothing to do with moral status. The simplicity of an argument is a strength, but sometimes it produces some uneasiness, especially when it is abstract, as is the case with this conceptual argument. For this reason, I will make some comments on it. The crucial premise is the first. As we have seen, to link moral status with intrinsic properties is the traditional conception. It has been challenged especially for some entities like embryos, and maybe some theologically inspired authors would still deny it on the basis of the consideration that the status of human beings consists in that they have been created by God and in God’s image. But here, we must be wary: what gives a high moral status (a dignity) to men is not the act of creation itself, but an effect of it: human beings are God’s image, and ‘to be God’s image’ is an intrinsic property. Creation and production cause the existence of some intrinsic properties in the being created or produced, but what counts for moral status is not the way these properties have been created or produced, but the fact that the being possesses them. Analogously, natural vitamin C and artificial vitamin C are differently produced, but they will be different (i.e. they will have different properties, causing different effects in our bodies) only if the way they have been produced gives them different intrinsic properties. Otherwise, they will be the same vitamin C. In short, the way a being is produced has, of itself, no impact on what it is. The case is more complicated with embryos and with low entities like microorganisms, as we have seen. If we include extrinsic properties and values in the basis of their moral 12 status, the conceptual argument would fall down for such entities, because the first premise would be rejected. The two other arguments will nevertheless show that we have no good reason to change our mind in the case of artificial life in general, and, more importantly, that this peculiar relational property ‘to be artificially produced’ does not modify moral status. Therefore, even if the first premise may not be true in some rather special cases, it has no consequence on the thesis that artificiality has no impact on moral status. The second argument is ontological and comes from the history of modern science (Baertschi, 2009, chap. 5). As is well-known, modern physics was born in the 17th century or a little earlier. It was born from the demise of scholastics (Aristotelian science), and some authors, particularly René Descartes in France and Robert Boyle in England, were eager to stress the novelty of their conceptions. These conceptions are expressed in several theses; two of them are important for my argument: 1. There exists an ontological identity between what is natural and what is artificial. 2. There exists only one kind of change in nature. Boyle is particularly clear on these points. In favour of the first thesis, he mentions the discovery that glass produced in a volcano’s chimney and in a glassmaker’s furnace is exactly the same glass, and he comments: ‘I know not why all the productions of the fire made by chymists should be looked upon as not natural, but artificial bodies; since the fire, which is the grand agent in these changes, doth not, by being employed by the chymist, cease to be and to work as a natural agent: and since nature herself doth, by the help of the fire, sometimes afford us the like productions that the alchymist’s art presents us’ (1666: 51). The two types of glass are the same glass, because their stuff and the fire that produces them are the same. The fact that nature (volcanos) or human beings are at the origin of the process is physically irrelevant in itself; it has no impact on the intrinsic properties of the product. The second thesis is also defended by Boyle. For him and physicists contemporaneous 13 with him, physical reality consists exclusively in moving corpuscles. Nature and human beings have consequently only one way at their disposal to change reality: to act on the local motion of corpuscles. Local motion is accordingly the only kind of change in nature, the old other kinds (generation, growth and qualitative change) being reducible to it. Following this conception, transmutation from lead to gold becomes possible and is hoped for by Boyle: ‘l could not see any impossibility in the nature of the thing, that one kind of metal should be transmuted into another (that being in effect no more than that one parcel of the universal matter, wherein all bodies agree, may have a texture produced in it like the texture of some other parcel of the matter common to them both)’ (1666: 94). The conception of the material world that is beneath these theses is still with us today. Contemporary science is modern science; there exists no theoretical gap between them comparable to the gap between them and Aristotelian science. In particular, for Aristotelian science, there was an ontological difference between natural and artificial beings, because only natural beings possess a nature, that is, an internal principle of change (Gilson, 1984: 155). Conversely, artificial bodies can only be acted on from outside, they have no ‘spontaneity’. For Boyle, this Aristotelian thesis is profoundly mistaken and, as we have seen, he wrote many pages to denounce it. Moreover, this new conception shows that the intrinsic properties of a being are independent of the way this being is created or produced, by human beings or by nature. In the case of glass – the example put forth by Boyle –, its intrinsic properties are the same, be it natural or artificial; therefore its ontological status remains the same. But glass has no moral status. Would it change anything if it were not glass but a living being that were produced? Could we afford a good reason to deny that they would have the same status, ontological and moral? I don’t see anyiv. I conclude therefore that even if somebody sticks firmly to the denial of the first premise of the conceptual argument, that is, even if he denies that the moral status of a being depends exclusively (and always) on what it 14 is, i.e., on its intrinsic properties or ontological status, he is not warranted to claim, in virtue of the ontological argument, that ‘to be produced by’ is a relevant extrinsic property for moral status. The third argument will definitely settle the matter. In the debate about cloning, it has been proclaimed that cloning is against human dignity, and international legal texts have endorsed this view (Council of Europe, 1998). But how should we understand that claim? If cloning is against human dignity, does it mean that a cloned child would be deprived of human dignity? Some persons were – and still are – afraid of that (Pinker, 2008). But it is sheer nonsense: human dignity is not something that can be lost because of a human intervention; human dignity is an intrinsic value grounded on intrinsic properties, and the properties relevant to the moral status of a child remain the same, be it procreated by cloning or by sexual intercourse (or by IVF)v. The argument by analogy is then straightforward: 1. A human being procreated artificially (by cloning or IVF) or naturally has the same moral status. 2. Therefore the moral status of a human being depends on what it is, i.e., on its intrinsic properties, and not on the way he has been procreated. 3. By substitution: a living being created artificially or naturally has the same moral status. 4. Therefore the moral status of a being depends on what it is, i.e., on its intrinsic properties, and not on the way he has been created. Consequently, there is no good reason to reject the first premise of the conceptual argument (identical with conclusion 4 of the argument by analogy). If not for all living beings, it is valid for most living beings, that is, in general. Conclusion 15 To believe that the properties ‘to be created or produced naturally’ and ‘to be created or produced artificially’ – in short ‘to be natural’ and ‘to be artificial’ in the genetic sense – have an impact on moral status is a mistake. If two living beings are similar but have been produced differently, and if they have a moral status, then their status is identical, except if the way they have been produced changes their intrinsic properties. To think otherwise is a mistake, as I have said. Nevertheless, this mistake is widespread. Why? There probably exist several reasons, some of them linked with a lasting and unconscious influence of the Aristotelian view. Another reason comes from a confusion of category. We tend to interpret the distinction between ‘natural’ and ‘artificial’ as an ontological distinction (with moral consequences), whereas it would be more appropriate to understand it as a moral distinction (with no ontological consequences). I will conclude with some reflections on this point, inspired by Ronald Dworkin. Habermas has already given us a clue when he spoke of a change in ‘our ethical self-understanding’. He is wary about this change in so far as it pertains to a modification of our nature through genetic engineering. Our topic does not concern a re-creation of man, but the artificial creation of organisms in general. Therefore we do not have to bother about eugenics, as there is no attempt to modify the human germ. What remains is the move of the frontier between what is given to us (the natural) and what we do (the artificial). And since the domain of morality concerns what we do, this move has a moral impact. What impact? An impact on our responsibility. The structure of our moral experience, says Dworkin, ‘depends, crucially, on a fundamental distinction between what we are responsible for doing or deciding, individually or collectively, and what is given to us, as a background against which we act or decide, but which we are powerless to change’ (2000: 443). When our power increases, our responsibility extends accordingly. With contemporary biotechnologies, our power increases dramatically, then our responsibility too. It is or can be unsettling, but it is 16 not a radically new situation: for a long time, technosciences have made their moral demands on us. As Theo van Willigenburg says: ‘Again and again, we need to reconstruct the border between actions and happenings’ (2008: 154). Therefore, we can approve this statement made by Holmes Rolston III: ‘It might seem that ending the history of a species now and again is not far out of line with the routines of the universe. But artificial extinction, caused by human encroachments, is radically different from natural extinction. Relevant differences make the two as morally distinct as death by natural causes is from murder’ (1985: 72). It is radically different, but not because human action would have a different ontological effect from natural ‘action’, but because human beings are responsible for their acts, whereas nature is not (it even does not act; natural events only happen). We can now see clearly that the mistake of believing that the artificiality of artificial life and the synthetic procedures of synthetic biology have an impact on moral status is profound. If they actually have an impact on our responsibility towards ourselves, towards nature and towards the beings we create and will continue to produce, the moral status of these beings has nothing to do with the fact that we and not nature are their creators.

It would not be valid for states of affairs, actions and events, because some of them are relational in character. For example, the moral significance of a death will be different depending on the manner it takes place, whether it is brought about by nature or by a murderer. ii A meta-ethical observation is still in order. This thesis does not have any privileged relationship with moral realism. It states that intrinsic value supervenes on intrinsic properties, but remains silent on the nature of this relationship. It can be read in a realist spirit, but in an antirealist spirit as well. if, for instance, we understand it in the following manner: the intrinsic value of X is projected on X on the basis of its intrinsic properties. Therefore it is inaccurate in my opinion to assert that, for an anti-realist, every value is relational. iii I put “naturally” between quotes, because naturally means here conventionally, that is a kind of artificiality (in the genetic sense of the term). iv Of course, one could reject these tenets of modern science and stick to the Aristotelian position; but it is in my mind a rather desesperate move. v This argument says nothing in favour or against cloning and remains compatible with considering cloning as an infringement on human dignity. Analoguously, the three arguments I have offered do not vindicate the morality of creating artificial life, because it could be an infringement on the intrinsic value of living beings.
