Problems in deriving an ethical system from science.
If it can be done, why should it not be? The risks will be taken; one hopes that we will get away with them.
- Professor Steve Jones on new biological techniques.1 The public
perception of science includes a concerning lack of trust regarding scientists’ abilities to regulate their research and openly to submit to ethical limits and discussion about what should or should not be
done with regard to both future research and current application of science and technology. Obviously the main focus of the interaction of science and ethics must be biology, where impacts directly
affect human life and health. Medical ethics is important, but here I shall focus on the rapidly growing and changing area of importance found in what has been dubbed ‘bioethics’, or more specifically of late,
‘genethics’. With the public frustrated and worried about lack of consultation and ignorance about what scientists can and should be investigating, it is troubling to read a prominent genetics professor
rejecting claims that science should answer to claims of higher moral authority:
[Interviewer] You have said that ethics is to science what pornography is to sex. You’re none too keen on it. Well, no, I’m not. It is vaguely interesting, but I don’t know much about it. If you ask who has gained most from the Human Genome Project, the answer is clearly the ethics industry. There
are now great glass towers of ethicists scattered across US campuses that were not there before, that are being funded by genetics. The Human Genome Project is spending 1 per cent of its income on
ethics. That strikes me as really weird. And it’s simply a matter of observational fact that ethics always follows science. And it’s going to continue to do so. [The reverse is] a Dark-Age attitude... [that]
doesn’t work. I find the whole ethical argument in genetics so peculiar. I just don’t
understand what these people are banging on about.2 These remarks are worrying for several reasons. Firstly, a ‘spokesman’
for science who writes a regular column in a broadsheet appears either not to understand the ethical questions the public is concerned with in regard to genetics, or else he does not care. He regards
the Human Genome Project’s investment in the ethical considerations of its work, which other scientists are keen to draw attention to in defence of science, to be a waste of time - certainly directly against the
tide of public opinion. But more importantly he believes that ‘ethics always follows science’ - both trying to draw a distinction between science and technology,
and also implying that ethical systems should only deal with relating human behaviour to what science has already discovered, not how it practises discovery.
This first distinction is not easily made in practice, however. If ethical considerations are only to be brought to bear on technological applications of science, then one is left with the problem of how to
judge the use of technology in scientific research. For instance, GM crops grown for research purposes might still pose a threat to other crops by the uncontrollable spread of pollen; to research
genetic benefits for reproduction might mean the experimentation on and death of many embryos. The use of technology is bound up in the practice of science, and no general delineation can be drawn. Jones
argues, ‘You can put ethical limits on the application of science, but that, I think, is quite a different thing [to ethical interaction with science]. I think you have to differentiate science from
technology.’3 But such a differentiation cannot be made in practice. The second issue raised here - ethics is subordinate or irrelevant
to science - is typical of the school of scientific thought known as (though usually they deny the categorisation) ontological reductionism, or ‘nothing-buttery’. Its representatives, such ambassadors of science as
Richard Dawkins and Daniel Dennett, promote the primacy of the scientific explanation and often its fundamental exclusivity as a source of truth. I will flesh out here what Jones means by ‘ethics follows
science’. Jones considers the opposite (science following ethics) to be, ‘a Dark-Age attitude. I mean the Dark Ages were a situation when ethics led and everything else had to follow.’4 By ‘ethics follows science’ he is not arguing that moral philosophers should be on hand to be involved with constructing the ethical implications of each scientific innovation - he has already expressed his amazement that the HGP should want to involve ethicists in its research. Rather, Jones denies that science and ethics have any interface at all (‘I can’t see how it [science] could have any responsibilities’; he has been quoted as saying that ethics is to science what pornography is to sex.5) and argues that science should be functioning independent of ethical controls because, ‘if it can be done, why should it not be?’6
If science exclusively tells us ‘how things are’ and provides the only reliable insight into the world, then we must either say that our moral inclinations are fictions
produced by the epiphenomenon of mind, or that they are somehow based in biological phenomena. The first of these cases regards ethics as meaningless; the second looks to science to provide any basis we seek
for what we should do in a situation. We cannot consider here the philosophy of mind and its place in scientific explanation, but the second case is to be addressed in more detail.
There is a tendency among followers of forms of scientism to attempt to draw the answers to ethical questions from the explanations of science. The philosopher of mind Daniel
Dennett at least seems aware of the problems here in leaning too heavily towards the ‘naturalistic fallacy’. This observation was a development of G E Moore, drawing from Hume. Hume claimed it was not
possible to derive a deontological imperative from a statement of fact - that is, an ‘ought’ from an ‘is’. In Humeian eyes, moral judgments are formed from moral sentiments - feelings of approval or disgust
are interpreted as feelings of intrinsic value or vice in an object.7
We must not however be so cautious as to conclude that the facts are entirely irrelevant: It does not follow... that facts have no bearing on values, only that they do not logically entail them.8
For instance, simplistically, if use of a bacterial weapon results in death, then its use can be condemned as wrong - but only if we first condemn as wrong the action of murder. That is, the act
of germ warfare can be categorised as morally wrong by the combination of facts and a value system. The simple consequence of people dying as a result of the weapon does not make the weapon wrong in itself -
we must interpret the facts against an external system of values which tells us how to make a judgement, knowing beforehand that murder is wrong. An example of forming an identity from facts and normative
values is the conflation of the results of natural selection and what is morally correct: ‘The good is simply that which evolution through selection has led us to regard as good.’9
Although Dennett rejects the naturalistic fallacy10 of simply deriving ‘ought’ from ‘is’, he sees that we must draw our ‘oughts’ from somewhere; and, drawing on his form of naturalism, he tries to ground that somewhere in ‘an appreciation of human nature - on a sense of what a human being is or might be, and on what a human being might want to have or want to be.’11 These vague conceptions of humanity he locates in both scientific and social sources. Yet even what explanatory
potential Dawkins and Dennett allow to the social part of life, they also claim it to be under scientific explanation - as memes.12 The idea of a meme is often still imprecise in definition. Dawkins describes the meme as ‘a unit of information residing in a brain... [having] a definite structure... [and possessing] phenotypic effects, which are its consequences in the outside world.’13 These phenotypic effects include the identities of such memes as ideas, pieces of music, religious beliefs and moral conditionings. Sometimes memes are criticised in
comparison with viruses - religious ideas especially (from Dawkins) - sometimes they are admired, like emotive pieces of music. In the same way that memes’ development and distribution can be compared to
that of genes, this memetic ambiguity of virtue mirrors the problem Dawkins and others have with genetic ambiguity. If the genes they reveal to us are selfish, and genetics is normative as well as
descriptive, why do they encourage rebellion against the selfish gene? If the genes are not normative, but are selected for because of advantage to the species, how can we choose which genes to regard
as good and bad, and which memes? If a person’s genetic makeup shows a tendency towards a certain type of behaviour or state of health, we are no more able to judge from the scientific data alone whether
or not the tendency is good, as we are able to judge whether a meme is good in itself. The Dawkins school appears to regard all altruism as really
self-interest beneficial for evolution, whether enlightened as such or unrealised. Dawkins appears to contradict the selfish nature of the gene by stating, ‘Nice guys finish first’14;
the type of self-interest required to satisfy such a denial of positive morality has developed considerably from a simple concept of selfishness into a complex community-based co-operation. Of course
this is a difficult position to maintain: [Dawkins] has found genuine altruism, ideal if not yet
as real as he wishes. It is puzzling to say where he found this, since he has dismissed all ethics prior to Darwin as worthless15, and all he can find in Darwinism is
a disposition to selfishness, which is the wrong answer.16 The meme may be a useful explanatory construct in some ways, but
it is ill equipped to answer the question of where our need for deontology comes from.
E O Wilson also has trouble generating generosity from selfishness in his sociobiology17, especially in the area of environmental concern.18 He regards evolution as the panacea for metaphysical problems:
They evolved by natural selection. That simple biological statement must be pursued to explain
ethics and ethical philosophers, if not epistemology and epistemologists, at all depths... The time has come for ethics to be removed temporarily from the hands of philosophers and biologicized.19
Both Wilson and Ruse agree that science exclusively explains (away) morality. Wilson states, ‘Human behaviour... is the circuitous technique by which
human genetic material has been and will be kept intact. Morality has no other demonstrable ultimate function.’20 Ruse claims, ‘Morality [or rather belief in it]... is merely an adaptation put in place to further our reproductive ends... In an important sense, ethics... is an illusion fobbed off on us by our genes to get us to co-operate.’21 But such explanations are neither satisfying or compelling with the problem remaining of reconciliation between how our ‘genes tell us to behave’ and what we generally agree to be the right way to behave. Moreover, even if a strong moral sense is beneficial for evolution, it might also possess another dimension besides, which might be its primary function. Morality may indeed ‘further our reproductive ends’ but that need not ‘merely’ be its function.
There are further dangers in using science as a basis for ethics: scientific theories change over time, being rejected or replaced or developed; should
our ethics change with the developing scientific vision of the world? Questions of realism become important here, as well as whether or not scientific descriptions should be taken to be normative and,
if so, why. Another issue concerns whether or not there is or should be a boundary to scientific explanatory power? Dawkins and others insist that everything of any significance can be explained in
scientific terms alone, but many have questioned their right to set science up as the only reliable source of explanation. In conclusion, it remains highly
unlikely that genetics can provide a workable reliable basis for a system of morality, despite the claims of some prominent scientists. The rapid development of biological sciences and the breadth of
their application requires comprehensive guidelines to be enforced for both research and application, but these guidelines must be drawn from external standards with the knowledge input of science, rather
than relying on what is possible as a rule for what should be.
