CHAPTER 1
Introduction: Exploring the Breadth & Depth of Being Human
This book derives from public lectures given in Oxford during Hilary Term 2010, based on the presumption of man-in-God's image as proclaimed in the first chapters of Genesis. Yet I deliberately turned that precept round to enquire – 'Are we made in God's image?' – and if so, what characteristic(s) make us so special in claiming that divine resemblance. The alternative, perhaps a little less impressive, relies on origins from apes. This book elucidates our evolutionary origins and status as human beings: but, in addition, it enlarges the curriculum in dealing not only with the various disabilities which confront us in this world, but also with our beginnings and endings, including abortion and infanticide, as well as the legalities and theology of assisted dying. The chapters included thereby provide a comprehensive picture of human life as lived by many on this planet.
The reader is first invited to become conversant with human physical anthropology through evolutionary time (Chapter 2), and the biological specifics contributing to each individual lifehistory, through genes (Chapter 3), conscious-awareness (Chapter 4) and the acquisition of language (Chapter 5). Those aspects define Distinctiveness. In dealing with our physical evolutionary origins, I suggest that we are more distinctive than 'unique', relative to the higher apes. Despite sharing surprisingly closely linked genetic endowments (genomes) with them, our bodily features (phenotypes) are markedly different, as well as our cultural differences.
The widely held belief in human uniqueness is perhaps a biblical hangover from us being supposedly made in the image of God. The problem is in knowing what that axiom precisely conveys. Evolutionary novelty usually emerges from re-use of preceding material. Thus, in the step from invertebrate to vertebrate the existing genome was doubled thereby providing scope for newer, original developments. Humans do not possess genes that have arisen de novo, instead through genetic mutations and reduplications, helped by sexual forms of reproduction which reconfigure the genetic elements or 'genotype' contributed, and which influence bodily configuration or phenotype. Nowadays, we should realise that defining a 'gene' is very difficult (Chapter 3: Genes). Genes often work in 'groups', with multi-genes controlling the activity of many others in a different part of the DNA sequence.
Environmental influences on gene expression are being seen to play increasingly more important roles in their overall (Darwinian) activity and control. Thus the field of 'epigenetics' (non-Darwinian inheritance) relating to environmental effects is now emerging as an overwhelming super-dominant element in the way through which genes are activated and regulated, and thus how they are expressed. We come upon this in Chapter 7 (Can We Ascribe Moral Status to the Human Embryo-Foetus?), for example, where epigenetic influences witnessed through The Dutch Winter of Starvation, November 1944-April 1945; the impressive Avon County (Bristol, UK) Long-Term study of parents and children (ALSPAC); and the Swedish long-term observations of families in terms of dietary effects on the future lives of grandchildren and their health, have been documented with some surprising outcomes. Some of these latter effects, amazingly, are manifested through the male (paternal) line, bringing further important moral issues to play in relation to a prospective embryo-foetus in utero, apart from the more obviously well-known strictures applicable to women during the period of gestation itself.
We are beginning to progress beyond the idea that humans are driven by 'selfish' genes, and, derivative of that outmoded idea, the similarly overblown concepts of Evolutionary Biology, Evolutionary-Sociology, Evolutionary-Psychology and other neoDarwinistic 'Evo-this-and-that' things. Collectively, Raymond Tallis, and a former medical colleague of mine, refer to much of that as 'evo-rubbish'. The philosopher Roger Scruton dismisses it as 'neurononsense'. Nevertheless, the increasing role of environment in configuring what we become is of far-reaching importance to our understandings of bodily function and hence of personhood.
We do not have consciousness, we are conscious: that is, each individual is a conscious being, being conscious (Chapter 4: On Being Conscious). I am unsure whether science can solve the emergence of this quality from an astoundingly complex brain possessing around 30 billion nerve cells (known as neurones) and an even astronomically higher number of inter-neuronal connections, or 'synapses'. We know that a single neurone may be attached synaptically to as many as 10,000 other neurones, resulting in phenomenally intricate connections throughout the brain. Indeed, it is the vast and unimaginable synaptic connectivity in our brains which confers humankind's outstanding levels of cognitive and affective capacity.
However, the major conundrum centres on how subjective conscious-awareness is able to control an objective physical organ (when thinking, for example) when consciousness itself originates from that physical organ. Clearly there is a very tight connection between neural processes and cognitive outcomes about which we can only have speculative ideas. We need to be aware that the brain operates at several different levels, concurrently, but not necessarily within our conscious-awareness. Next, I touch on the evolutionary history of consciousness, and further consider when conscious-awareness develops in the foetal brain – an aspect of consciousness hardly considered in many other books on brain function, but functionally important. Despite the restricted lack of sensory input which obtains in the womb, it is evident that much conscious activity is present, at least during the last ten weeks (probably longer) of gestation: there is no such thing as a 'blank slate' at birth.
Apart from that, we all have the innate ability to render ourselves unconscious when we sleep: likewise when undergoing general anaesthesia. Many new insights about being conscious have arisen from the various studies into these latter phenomena.
On the other hand, much of learned conscious activity operates efficiently at sub-conscious level: so, why do we need to be conscious? For example, just consider the enormous success through evolutionary time demonstrated by bees, wasps, spiders and ants! Secondly, what is the evolutionary advantage of consciousness requiring brains to absorb 25% daily energy intake for their operation? That was an enormous biological gamble even albeit blindly accomplished – if we are true Darwinists. So how could that gamble have been prefigured in the progressive, blind mechanisms of selection? Thirdly, from some quarters, neurophysiological doubts about 'freewill' and our supposed ability to operate independently with our own choices have arisen. This leads on to considerations as to how we derive a sense of (and even believe in) the divine. Is the latter pure artefact conjured up by a brain that controls mind? Reflection on these many issues has an important impact on our belief systems and whether concepts of the divine, in the end, turn out to be mere cerebral make-believe.
Despite our sharing ~95% genetic homology with apes, why do humans speak? It is an extraordinarily novel development due, in part, to two key mutations involving the FOXP2 gene which arose during the relatively brief evolutionary period following our separation from chimpanzees, ~5 million years ago. That compares with the remarkably highly conserved (nonmutational) behaviour of this gene as far back as the origins of mice, ~100 million years ago – and even perhaps further back throughout evolutionary time (Chapter 5: On Having Language). It is highly pertinent to ask how and why a single amino acid substitution (from one of two mutations) should have come about and resulted in the foundations of articulatory speech and how that chance evolutionary change, an almost miniscule alteration, now underpins and has therefore shaped our highest intellectual faculties.
Speech is an indispensable requirement for abstract thinking, the use of metaphorical language, and the basis for religious beliefs. Despite occasional excited newspaper reports of socalled 'God-spots' in the brain, I pointed out some years back that there is no locus for a holy shrine within the brain, sheltered from the common vulgarities of secularly-based neural commerce. Our acceptance of divine presence and action is predominantly cognitively based on a faith in that divinity, and buttressed by forward-looking hope and belief in the propositions thereby arising. Apart from that there is, additionally, an inexorable evolutionary movement towards higher biological complexity, size, and burgeoning functional outcomes. This can be seen as a type of 'progression' (not of Enlightenment kind) towards the ultimate emergence of human beings, their big brains, and their extraordinary endowments, capacities and capabilities.
Next, I turn to Dignity, and its relevance to theological concepts of being human, and in the making of personhood. While genes, consciousness, and language certainly frame mankind within the evolutionary environment as well as the physical world which mankind inhabits, more than a purely physical anthropology is needed. In part, that includes the insatiable thirst for transcendence by bursting through barriers to conquer what lies on the other side. But in that pursuit of transcendence, we step outside ourselves (ekstasis): and through this action we discover the divine (Chapter 6: Theological Anthropology). The term Dignity underpins theological aspects of humankind, seen as a means of defining the true nature of humankind as persons, but of persons in relation with each other and the Godhead.
As this chapter will explain, our createdness imposes certain restrictions, in that we cannot escape the boundaries of our world – nor fully understand ourselves or others. That dilemma creates the further paradox of 'presence-in-absence'. And since all other humans are made in the same mould, they cannot provide answers to, or escape, these frustrating outcomes. The ultimate method of transcendence (the attempt to break out from ourselves and our physical circumstances) is to be in relation with an Other, that is, the Godhead, achieved principally through baptism.
In the early church, baptism was viewed eschatologically (through the Spirit towards the final consummation of creation), making the convert a member of the sacral community (on earth as in heaven) and a part of the Godhead – through 'dying' and 'rising with' Christ. This partial escape from the bondage of createdness is subsumed under the notion, within the Orthodox tradition, of 'godliness', or 'theosis' (Chapter 6: Theological Anthropology). This has no relationship to a 'soul', but does constitute a sacralised form of being or existence, apart from the being based on a fleshly body. Baptism thus provides continuity towards, and within, the Godhead once the corporeal self has dwindled and died. The role of baptism as a means of metaphysical re-birth 'from above' in establishing the person as 'unique' and as one known individually by the Godhead, figures heavily in my deliberations. Our guarantee is provided by the Chalcedonian Definition that there can be two (ontological) natures within one (human) person 'without confusion'. And that really is a gift given by the Godhead: we can achieve very little on our own.
The idea of being made in the divine image means becoming God-like, rather than being seen in some other guise or construction. The oft-used expression 'sanctity of the body or flesh', similar to 'made in God's image' are categories which, in somehow being thought to carry with them a kind of divine imprimatur, become barriers (conversation stoppers) which cannot, and should not, be transgressed. In disclosing a sense of divine authority, they tend to inhibit further thoughtful analysis of their meanings, and in my view fail to frame the uniqueness of the person. Therefore, I am unsympathetic to those precepts, which are easily overridden by other more appropriate and sustainable arguments.
For example, many would regard the medical advances through which the pre-existing, diseased body can be made more wholesome, to be an entirely acceptable mode of operation. That has been achieved through surgery, immunotherapy, pharmaceutical procedures, materials science, technological advances and so on, as major components of the clinical armamentarium. Despite their incursions into body and flesh (whether or not considered 'sanctified'), they should be welcomed. Even the Godhead might be pleased with the ingenuity and subtle research enterprises which underpin them. There are few, indeed, who would not have been beneficiaries of such protocols and their skilled application.
In proceeding and reflecting more specifically on the question of defining persons and personhood, we should note how definitions have changed through time, particularly since the Enlightenment. However, those are man-made definitions, which may therefore fail to do justice to defining an individual person. Moreover, the kind of definitions in force at any time considerably influences how we view each other, and how society interprets those definitions and accordingly manipulates its own agendas, jurisprudence and socio-political approaches towards society and individuals.
Current trends have reduced the definitional idea of a person to a collection of abstract qualities, for example, memory, ongoing interests, and future intentions. These definitions float tenuously in space, lacking a suitable ontological basis whether conceived anthropologically, sociologically or theologically. Since persons constantly change over the period of their lifetimes, it is difficult to know when some or all of these properties could be operative, and, of course, when they disappear. On those problematic grounds, a person would only truly come into view once certain arbitrary, pre-determined properties are satisfied. Is that really possible? On the other hand, such criteria exclude many who should be regarded as part of our community – the embryo-foetus, neonates, children, many disabled folk, the mentally ill, and the elderly and frail including those in end-oflife situations – and so are easily dismissed as so-called 'nonpersons'. From that position, it is an easy step for those categories of humanity to be regarded as worthless, unworthy and therefore available for disposal. My approach counters that tendency.
This difficulty first impinges on the status of the embryofoetus (Chapter 7: Can We Ascribe Moral Status to the Human EmbryoFoetus?) and whether it can be regarded as something that is of humankind and valuable. In two notably germane publications on this subject, Norman Ford's When Did I Begin? and the UK government-sponsored Report into Human Fertilisation and Embryology chaired by Baroness Mary Warnock, it was insisted that a 'person' (undefined by both authors) could only come into existence, and hence be recognised as such, once the last opportunity for twinning had passed and when the primitive streak had become visible on the developing early embryo, both occurring around 2 weeks after fertilisation. Here, personhood comes to be defined in terms of two biological phenomena, and nothing more. I am puzzled by how a biological structure can underpin moral decisions, and even the basis of law (Warnock).
In those two publications, all preceding stages in development were dismissed and deemed inconsequential. Some philosophers employ analogous arguments. Employing molecular genetics and biological data, I demonstrate the improbable basis for those conjectures, concluding by appropriate arguments from molecular biology that the new individual with a unique genome starts when most people imagine it to come into being – once fertilisation has taken place.
This is a more important conclusion than it appears at first glance. That is because the early embryo-foetus is not some kind of abstract entity, but a new individual with its own specific genome. That is the origin from which we all derive: it is not a mere inconsequential blob of cells as some apparently think. It is a reflection of the continuity of life from its initial emergence on the planet, since any foetus is not a new life, but continues the living-principle (of a living sperm and ovum) into a new, genetically unique, individual. Second, that new individual is conceived within a family setting, is influenced by the lifestyles and defined contingencies affecting its grandparents. Various long-term studies, including observations of current adults (but who were conceived during the intense starvation caused by the German occupation of Holland) demonstrate how the seeds of later adult illness are sown during embryogenesis – and before. These observations are of grave moral concern and should influence, for example, public health programmes. These are the considerations, among others, which impart to that conceptus moral dignity and therefore assign to it a respect which can be easily lost, forgotten or overlooked.
