The fact that, so far as the course of actual experience went, he could insist that it coincided with the customary views of ordinary life was felt, rightly, to be not enough to make it
Trang 1fact, is Dumont’s title) Bentham’s claim is that language
which looks as if it is describing what rights there actually
are is in fact suggesting what rights there ought to be That
is, instead of citing existing rights, the French Declaration
is giving reasons why there ought to be rights As
Ben-tham puts it in Anarchical Fallacies, ‘a reason for wishing
that a certain right were established, is not that right; want
is not supply; hunger is not bread’ So to suppose that such
rights actually exist is nonsense Even worse is to suppose
that we can be sure that the correct rights have been found
for all time For Bentham is a promoter of
experimenta-tion We have to keep seeing what utility is actually
pro-duced by particular systems of rights Hence it is an
additional mistake to think that any rights are unalterable
(indefeasible, imprescriptible) This mistake was also
made by the French Hence the famous slogan The
com-plete remark from which it comes is ‘natural rights is
simple nonsense: natural and imprescriptible rights,
rhetorical nonsense, nonsense upon stilts’
Natural rights was one attempted answer to the
ques-tion of the source of obedience to the state and the
condi-tions for legitimate revolution Another attempted
answer also popular in Bentham’s day was the original or
social contract This device, founding obedience on
agree-ment, was used by the leading contemporary defender of
British law William Blackstone Bentham ridicules such a
defence in his Fragment on Government For Bentham,
justi-fication of obedience to government depends upon utility,
that is upon calculation of whether the ‘probable
mis-chiefs of obedience are less than the probable mismis-chiefs of
resistance’
A contract will not work here for Bentham because, just
like rights, all real contracts are legal contracts Hence they
are produced by law and government; and cannot
there-fore be used to provide a foundation for law and
govern-ment Even if its force is not supposed to be the force of a
proper contract but merely that of a promise, or
agree-ment, this again will not help to provide justification For
whether someone (government or people) should keep
their agreements has, again, for Bentham to be tested by
the calculation of utility Yet if utility is to be the ultimate
justification of promise-keeping, it would have been
bet-ter to have started there in the first place, rather than (like
Blackstone) traversing a tortuous path through contracts,
original contracts, and largely fictional agreements Again
Bentham designates the supposed alternative source of
justification to be merely a fiction and, as he puts it in the
Fragment, ‘the indestructible prerogatives of mankind
have no need to be supported upon the sandy foundation of
a fiction’
Although all justification comes from utility, this does
not mean that Bentham can not support secondary ends;
that is, things which, if promoted, will normally tend to
increase utility He lays down four such intermediate ends
which should be promoted by the right system of law and
government: subsistence, abundance, security, equality
These form two pairs so that subsistence (the securing to
people of the means to life) takes precedence over
abun-dance; and securing people’s expectations takes precedence over equality The utilitarian argument for this depends upon the psychological claim that deprivation of the former member of each pair causes more pain than the latter Psychological assumptions also lie behind Bentham’s promotion of *equality He claims that (in general) equal increments of a good will not produce equal increments of utility (That is, he claims that there is diminishing mar-ginal utility.) Therefore, in general, provision of a particu-lar good will provide more utility for those who already have less than those who already have more; hence a gen-eral tendency towards providing goods for the less well-off; or equality
Bentham’s is a consequentialist ethic It looks towards actual and possible future states of affairs for justification
of right action, not to what happened in the past (For example, punishment is not retribution for past action, but prevention of future harms; obedience to the state is not because of some past promise, but to prevent future harms.) This is for Bentham the right, indeed the only pos-sible, way of thinking correctly about these matters It explains his central stance with regard to reform of the law The law he found was common law, made by judges, based on precedent and custom It came from history For this he wanted to substitute statute law, made by demo-cratic parliaments, and founded on reason These reasons would be independent of history and would be in terms of

Berdyaev, Nikolai Alexandrovich(1874–1948) Influen-tial Russian religious philosopher who, after a youthful flirtation with Marxism of neo-Kantian persuasion, developed a form of Russian idealism sometimes called
‘Christian existentialism’ According to Berdyaev, what truly exists is spirit, conceived as a creative process: every existent, including God, is a self-determining subjectivity engaged in the realization of value Human beings attain personhood only if they realize their creative essence, which they may do in a society which embodies true
com-munity (sobornost') and which aspires to identity of pur-pose with God Berdyaev oppur-posed his vision of ‘personal socialism’ to both bourgeois individualism and any collect-ivism that subordinates the individual to the community
A perceptive critic of totalitarianism, he was expelled from the USSR in 1922 and settled in Paris Since the demise of the Soviet Union, Berdyaev’s writings have enjoyed

Bergmann, Gustav (1906–87) Austrian-born American
philosopher, who taught at the University of Iowa for
forty years, Bergmann disdained all versions of
*material-ism, though he did defend methodological
*behav-iourism A member of the Vienna Circle and influenced by
Moore, Russell, and Wittgenstein, Bergmann wrote
extensively on individuation, universals, and
intentional-ity, often setting out his views by contrasting them with
those of others: Meinong, Brentano, Husserl, Quine,
Strawson, and so on As an ideal-language philosopher,
Bergmann tried to design a formalism which allows for
the analytic–synthetic distinction and the syntactical
fea-tures of which point to solutions to the ontological
prob-lems Bergmann’s most striking contribution emerges in
his attempt to show that the truth-bearers of thoughts are
mental states which, though simple, have truth-makers

Bergson, Henri-Louis(1859–1941) French philosopher of
Anglo-Polish extraction who worked mainly at the Collège
de France in Paris Bergson is famous for two main
doc-trines, those of duration and the élan vital In a letter written
in 1915 he speaks of ‘the intuition of duration’ as ‘the core
of the doctrine’ which any summary of his views must start
from and constantly return to Duration is time at its most
timelike, as we might put it For the scientist time is a
homogeneous medium which can be divided into periods
of equal length, and treated for the purposes of the calculus
as analysable at the limit into an infinity of instants with no
length None of this holds for duration, which is
heteroge-neous, ever-changing without repeating itself, and cannot
be divided into instants (though one interpretation sees
Bergson as led to duration by reflecting on the calculus in
terms of Newton’s doctrine of ‘fluxions’) Duration is
*time as experienced by consciousness, and perhaps
Berg-son’s most important insight is that we do not experience
the world moment by moment but in a fashion essentially
continuous, illustrated by the way we hear a melody,
which cannot consist simply in hearing a succession of
dis-jointed notes Past, present, and future cannot be so
sep-arated that it becomes impossible for us to know of the past
because only the present is ever present to experience It is
perhaps rather strange that of the two main philosophers
of time of the late nineteenth and early twentieth
cen-turies, Bergson and McTaggart, neither seems to have paid
any attention to the other Bergson wrote his main
rele-vant works before McTaggart’s famous 1908 article, but he
never overtly reacted to it and shows no signs of being
influenced by it in his later writings (despite being fluent in
English and having lectured in England)
Born in the year of The Origin of Species Bergson was
familiar enough with the conflict between evolutionism
and religion His book Creative Evolution, introducing the élan vital as a sort of life force, probably owed its
popular-ity partly to his attempt, backed by scientific as well as philosophical arguments, to develop a non-Darwinian evolutionism that made room for religion, albeit not for orthodox Christianity He envisaged a process of constant change and development, irreversible and unrepeatable (so that biology is a fundamentally different science from
physics), and governed by the élan, which uses effort and
subtlety to overcome the resistance of matter (an echo of
the divine Craftsman in Plato’s Timaeus?), but is not drawn
by some pre-envisaged end, for that would be a mere
‘inverted mechanism’
Later in life Bergson turned his attention to morality Just
as duration could never be generated from time considered
as isolated moments (an argument he also used against Zeno’s paradoxes of motion), so, he claimed, universal benevolence could never be achieved by starting with group loyalties and making the groups ever wider Group loyalty always required a contrasting out-group, and could
be transcended only by a qualitative leap of the sort taken
by mystics in their love of all mankind
Another application Bergson makes of his general phil-osophy comes in his treatment of *laughter in the short book of that name Man is a spiritual outgrowth in a world which works, along with his body, on mechanical prin-ciples, and laughter arises when he is seen as reverting to the mechanical level, primitively when he slips on a banana skin, sophisticatedly when his conscious actions unconsciously mimic the mechanical a.r.l

Berkeley, George(1685–1753) Berkeley is a most striking and even unique phenomenon in the history of philoso-phy There have been many philosophers who have constructed bold and sweeping, often strange and aston-ishing, metaphysical systems Some, particularly in the English tradition—for example, Thomas Reid in the eight-eenth century or G E Moore in the twentieth—have been devoted to the clarification and defence of ‘common sense’ And some have made it their chief concern to defend religious faith and doctrine against their perceived enemies It is the peculiar achievement of Berkeley that, with high virtuosity and skill, he contrived to present him-self in all these roles at once His readers have differed in their assessments of the relative weights to be accorded to these not clearly compatible concerns It is easy to read him as primarily a fantastic metaphysician—a line taken,
to his baffled chagrin, by almost all his own contempor-aries More recently some, by reaction against this, have perhaps tended to overstress his credentials as the
Berkeley, George 91
Trang 3champion of *common sense His religious apologetics, if
scarcely his dominant interest, were unquestionably
sin-cere But mainly one should try to see how, not merely
temperamentally but as a lucid theorist, he really did
con-trive to make a coherent whole of his diverse concerns
The works on which Berkeley’s fame securely rests
were written when he was a very young man Born and
educated in Ireland, he first visited England in 1713, when
he was 28, and his Three Dialogues between Hylas and
Philo-nous was published in that year But he had by then already
published his Essay towards a New Theory of Vision (1709)
and his major work A Treatise Concerning the Principles of
Human Knowledge (1710) His later philosophical writings
do little more than defend, amplify, and in one or two
respects amend the comprehensive views thus early
arrived at It is, in fact, evident from his correspondence
that in his later years concern with philosophical issues
was for long periods wholly displaced by other interests
In this respect he differs markedly from John Locke—the
chief target of his criticism—whose Essay Concerning
Human Understanding (1690), long meditated and much
revised, did not appear till its author was nearly 60 The
young Berkeley was apt to commend Locke’s thoughts,
not without irony, as quite creditable for one so far
advanced in years
A major motive of Locke’s philosophy—with which
Berkeley was well acquainted in his student days—was to
work out the implications of the great achievements of
seventeenth-century science It had been established
beyond all question, he took it, that the material universe
was really, essentially a system of bodies mechanically
interacting in space—bodies ‘made’, so to speak, of
mat-ter, and really possessing just those qualities (*primary
qualities) required for their mechanical mode of
oper-ation—‘solidity, figure, extension, motion or rest, and
number’ This was the bedrock of Locke’s position These
bodies operate on, among other things, the sense-organs
of human beings—either through actual contact with the
‘external object’ or, as in vision, by ‘insensible particles’
emitted or reflected from it This mechanical stimulation
in due course reaches the brain, and thereupon causes
*‘ideas’ to arise in the mind; and these are the items of
which the observer is really aware In some respects these
ideas faithfully represent to the mind the actual character
of the ‘external world’—bodies really do have ‘solidity’,
etc.—but in others not; ideas of, for instance, sound,
colour, and smell have no real counterparts in physical
reality, but are merely modes in which a suitably
consti-tuted observer is affected by the appropriate mechanical
stimuli
Berkeley came very early to regard this picture of the
world as at once absurd, dangerous, and repulsive It was
absurd, he argued, because it implied a fantastic
*scepti-cism, plainly intolerable to good common sense For how
could an observer, aware only of his own ideas, know
anything of Locke’s ‘external world’? Locke himself had
insisted that colour, for example, is only an apparent, not a
real, feature of that world; but how, in fact, could he know
that our ideas correctly represent to us, in any respect, the world’s actual character? A sceptic has only to suggest that our ideas perhaps mislead us not merely in some ways, but
in every way, and it is evident that Locke is left helpless before that suggestion—unable, indeed, even to assure himself that any ‘external’ world actually exists That is surely, for any person of good sense, an intolerable position
But it is also dangerous, Berkeley holds For—besides this general leaning towards an absurd scepticism—the
*‘scientism’, as one may perhaps call it, of Locke’s doc-trine seemed to lead naturally towards materialism and,
by way of universal causal determinism, to atheism also, and therefore, in Berkeley’s view, to the subversion of all morality God is brought in by Locke as the designer, cre-ator, and starter of the great Machine; but could he show that matter itself was not eternal, with no beginning and
no creator? Might God turn out to be superfluous? Again, though Locke himself had made the supposition that minds are ‘immaterial substances’ and no doubt hoped to sustain a Christian view of the soul, he had confessed that
he could not disprove the counter-suggestion that con-sciousness might be merely one of the properties of mat-ter, and so wholly dependent on the maintenance of certain purely physical conditions Thus Locke’s theories
at best permit, at worst positively encourage, denial of God’s existence and the soul’s immortality; with that denial religion falls and, in Berkeley’s view, drags morality after it
Finally, it is clear from, though less explicit in, Berke-ley’s words that he was simply oppressed and repelled by the notion of the universe as a vast machine Locke loved mechanisms He delighted in metaphors of *clocks and engines, springs, levers, and wheels, and indeed took mechanics to be the paradigm of satisfactory intelligibil-ity All this Berkeley detested God’s creation, he was sure, could not really be like that—particularly if, in order to maintain that it is, we have to assert that its actual appear-ance is delusive, that ‘the visible beauty of creation’ is to be regarded as nothing but ‘a false imaginary glare’ Why, to embrace such a nightmare, should we deny the evidence
of our senses?
What then was to be done? Berkeley thought that the solution of all these perplexities was obvious, luminously simple, and ready to hand As he wrote in his notebook, ‘I wonder not at my sagacity in discovering the obvious though amazing truth, I rather wonder at my stupid
inad-vertency in not finding it out before.’ The solution was to deny the existence of *matter.
First, Berkeley insists, this odd-looking denial is wholly supportive of common sense On Locke’s own admission
we are never actually aware of anything but our own ideas; to deny the existence, then, of his ‘external objects’, material bodies, is not to take away anything that has ever entered into our experience But not only so; it must also put an end to all sceptical questioning For Locke was obliged to concede to the sceptic that our ideas might mis-lead us about the real character of things, precisely
92 Berkeley, George
Trang 4because he had regarded things as something other than,
merely ‘represented’ by, our ideas But if, eliminating the
supposed material body, we adopt the view that the
ordin-ary objects of experience simply are ‘collections of ideas’,
it will be plainly impossible to suggest that things may not
be as they appear to us—even more so, to suggest that
their very existence might be doubted If an apple is not an
‘external’ material body, but a collection of ideas, then I
may be entirely certain—as of course, Berkeley says, any
person of good sense actually is—both that it exists, and
that it really has the colour, taste, texture, and aroma that
I find in it Doubt on so simple a matter could only seem to
arise as a result of the quite needless assertion that things
exist, distinct from and in superfluous addition to the ideas
we have
But surely, it may be objected, our ideas have causes
We do not generate our own ideas just as we please; they
plainly come to us from some independent source; and
what could this be, if not the ‘external world’? But this
point redounds wholly, Berkeley claims, to his own
advantage For to cause is to act; and nothing is genuinely
active but the will of an intelligent being Locke’s
inani-mate inani-material bodies, therefore, could not be true causes
of anything; that ideas occur in our minds as they do, with
such admirable order, coherence, and regularity, must be
by the will of an intelligent being And of course we know
that there is such a Being—God, eternal, omnipresent,
omnipotent, ‘in whom we live, and move, and have our
being’, ‘who works all in all, and by whom all things
con-sist’ Berkeley wonders at the ‘stupidity and inattention’ of
men who, though every moment ‘surrounded with such
clear manifestations of the Deity, are yet so little affected
by them, that they seem as it were blinded with excess of
light’ (Principles, para 149).
Finally—and certainly, for Berkeley, most
satisfactor-ily—he finds himself in a position to put the physical
sci-entist firmly in his place For if there is no matter, no
material bodies, there are no ‘corpuscles’, no ‘insensible
particles’; that whole corpus of mechanistic physical
the-orizing in which Locke delighted cannot possibly be true,
for there is simply nothing for it to be true of At first, in
his early (though major) work the Principles, Berkeley
embraced this position in the most unqualified form
There is a modest role for the scientist, he there argued, in
observation and description of the objects of experience,
in the search for true generalizations about the course of
our ideas, that is, of natural phenomena; but all reference
to items supposedly ‘underlying’—supposedly
explana-tory of, and according to Locke more ‘real’ than—human
experience, must be dismissed as moonshine, the product
of mere confusion But later—regarding, perhaps, as
over-drastic this wholesale dismissal of not only Locke but also,
for example, Gassendi, Newton, and Boyle—he devised a
strikingly ingenious variant position in which, though
running hopelessly against the main tendency of his age,
he foreshadowed the ideas of many contemporary
philosophers of science In his pamphlet De Motu of 1721,
he still maintained that corpuscular theories of matter, for
example, or the particle theory of light could not be true; but they may nevertheless be allowed, not indeed as truths, but as useful fictions The ‘theory’ of the corpuscu-lar structure of matter makes possible the exact mathe-matical expression of formulae, by which we can make very valuable calculations and predictions; but there is no need to make the supposition that the corpuscles and par-ticles of that theory actually exist So long as it is useful to
us to speak and to calculate as if they exist, let us so speak
and calculate Such intellectual dodges ‘serve the purpose
of mechanical science and reckoning; but to be of service
to reckoning and mathematical demonstrations is one thing, to set forth the nature of things is another’ It is Locke’s concession, one might say, to the physical
scien-tist of metaphysical authority that Berkeley, at every stage,
implacably opposes
Two of Berkeley’s later works may be mentioned
briefly His Alciphron (1732) is a long work in dialogue
form, in which the tenets of Anglican orthodoxy are defended against various types of ‘free-thinking’ and
*deism Though able enough, it suffers from the artificial-ity of the convention, and has limited interest now that the controversies which prompted it are moribund His last
work was Siris (1744), a very strange, even baffling
pro-duction, in which a most uncharacteristically rambling, ponderous, and speculative statement of some part of his earlier opinions leads on to an inquiry into the virtues of
*tar-water, a medicine which Berkeley made popular, and for the promotion of which he worked in his later years with surprising zeal
Berkeley’s main work was slow to exert any influence
on philosophy, though his limited early Essay on vision
became fairly well known His criticism of Locke, though not always ideally fair, was for the most part powerful and well taken; and the transition to his own remarkable doc-trine of a wholly non-material, theocentric universe,
whose esse was percipi, and in which human ‘spirits’ were
conceived of as conversing directly with the mind of God, was at least a feat of dazzling ingenuity But this doctrine was too extraordinary to be taken quite seriously The fact that, so far as the course of actual experience went, he could insist that it coincided with the customary views of ordinary life was felt, rightly, to be not enough to make it actually the same—he was far indeed from being accepted
as the friend of common sense His strikingly original
phil-osophy of science—really the fundamental area in which
he dissented from Locke—was also much less persuasive then than it would be if it were propounded today In the early eighteenth century it was still possible, even natural,
to regard physical theory as merely a kind of extension of ordinary observation, offering—or at any rate aiming at— literal truths of just the same kind, and couched in much the same terms, as those of everyday experience Today the sophistication of physical theory has made this difficult, or indeed impossible, to believe; but to deny it then was prob-aby felt not only to be perverse and unnecessary, but also— entirely rightly, in Berkeley’s case—to constitute an attempt to undermine the physicist’s prestige It was his
Berkeley, George 93
Trang 5misfortune that he opposed, even hated, the ‘scientific
world-view’ at a time when that view was in the first flush
of its general ascendancy
Berkeley was born near Kilkenny, and educated at
Kilkenny College and, from 1700, at Trinity College,
Dublin He was a Fellow of that college—though often
absent—from 1707 to 1724 Ordained in 1709, he was
appointed Dean of Derry in 1724, and Bishop of Cloyne in
1734 He married in 1728, and died at his lodgings in
Holy-well Street, Oxford, in 1753, while overseeing the
intro-duction of his son George to Christ Church Berkeley’s
life, apart from his philosophical writings, is remarkable
chiefly for his curious attempt in middle life to establish a
college in Bermuda The purpose of this project was
mainly missionary Berkeley’s hope was to attract to his
college both the colonial settlers of America and the
indigenous American Indians, so that they would in due
course return to their communities as ministers of religion
and purveyors of enlightenment As Dean of Derry he
devoted to this scheme his considerable energies, powers
of persuasion, and personal charm, and at first succeeded
in securing for it both private and official backing He was
granted a charter, raised substantial funds by private
sub-scription, and was even promised an ample parliamentary
grant But the scheme was really impracticable, and was in
the end recognized to be so Bermuda—as he was perhaps
not clearly aware—is far too distant from the American
mainland to have been an attractive location for his
insti-tution Berkeley himself set out boldly for America in
1728, but in his absence doubts and hesitations began to
prevail in London He waited nearly three years for his
promised grant to be paid over, but in 1731 the Prime
Min-ister, Walpole, discreetly indicated that there was no
prospect that his hopes would be gratified The house

Berlin, Isaiah(1909–97) Berlin was born in Riga, Latvia,
into a Jewish family that migrated to England in 1919 in the
wake of the Bolshevik Revolution He studied at Oxford
and taught philosophy there in the 1930s, becoming a
sig-nificant part of the movement that developed into
‘ordin-ary language’ philosophy, and publishing influential
papers on the logic of counterfactual conditionals He
wrote his first book in 1939, on Karl Marx During the war,
he had diplomatic postings in Washington and, briefly,
Moscow (‘one week’s work in an embassy—that is my
experience—is less of a strain than one day’s teaching at
Oxford’) and met outstanding Russian writers such as
Pasternak and Akhmatova Back in Oxford, Berlin’s
inter-ests shifted more to the history of ideas with particular ref-erence to political thought, and in 1957 he was knighted and appointed to the Chair of Social and Political Theory at Oxford He was the first President of Wolfson College, Oxford (1966–75), and President of the British Academy from 1974 to 1978
Berlin was rare amongst historians of thought and phil-osophy in being himself a substantial philosopher, and it is this, plus considerable powers of empathy and a wide range of learning, that gives his explorations of the work and impact of thinkers as diverse as Vico and de Maistre, Machiavelli and Herder, such power and fascination A lifelong secular liberal, Berlin’s writings on liberal theory have had a lasting impression on contemporary political philosophy, his discussions of the concepts of negative and positive liberty being his best-known contribution Equally significant, however, has been his passionate advocacy of the view that the ends of life cannot form a unified whole
Although his concerns and heroes were eclectically European, Berlin’s method and intellectual temper were rooted in English philosophical tradition with its stress on clarity, argument, and vigorous debate c.a.j.c

Bernoulli’s theorem. The theorem is named after the Swiss mathematician who first proved it, Jakob Bernoulli
It is also known as the ‘weak law of large numbers’, and was historically the first of a cluster of famous limit the-orems of mathematical *probability It states that if
succes-sive outcomes, A and not-A, of a sequence of n trials are independent, and the probability of A at each trial is p, then the probability that the relative frequency of As in the n trials differs from p by more than an arbitrarily small number tends to 0 as n increases The relation between
probabilities and frequencies established by the theorem led many people, including Bernoulli, to believe that prob-abilities could be inferred from observed frequencies Whether such an inference is possible is still unresolved

Bertrand’s paradox,due to Joseph Bertrand, brings out
an inconsistency in certain *a priori ways of calculating
*probability What is the probability that the length k of a
‘randomly selected’ chord to a given circle is less than the
length l of a side of an equilateral triangle inscribed in the
circle? Viewing the chord as determined by a line through
a point p on the circumference, k < l if and only if the angle
between the chord and a tangent at p is either < 60° or
> 120° This is ⅔ the possible angles, which suggests that
the probability that (k < l ) =⅔ But one of many other
pos-sibilities is to view the chord as determined by a
perpen-dicular to a radius k < l if and only if the perpenperpen-dicular
intersects the radius over half-way between the mid-point
of the circle and the circumference, suggesting the
prob-ability that (k < l ) =½ The ‘a priorist’ technique of
finding a ‘random’ method to generate the chord and then
dividing the possibilities for that method to get the
prob-ability thus seems to lead to inconsistency, unless some
method can be shown to be the ‘right’ one j.c

bioethicsis the study of the moral and social implications
of developments in the biological sciences and the related technology This entails considering the value that is or should be accorded to various forms of life Are human beings morally entitled to use other living things, plants or animals, in any way that they choose? Is there a special
‘sacredness’ or ‘dignity’ attached to human life? If so, does the stage of development that a human life has reached nevertheless make a difference to the morality of des-troying it? Such questions as these are the concern of bioethics It is a subject that grew enormously in the late twentieth century, and most universities now have professional bioethicists among their members, whether interested in broadly environmental and ecological issues
or in medical applications of the new technologies Bioethics is concerned, for example, with the rights and wrongs of the genetic manipulation of crops and animals, including human animals (and at this point there is an overlap between bioethics and Green political theory) How are possible advantages to impoverished countries
of genetically modified crops, designed to resist drought
or flooding, to be weighed against the possible exploit-ation of the poor by chemical or pharmaceutical com-panies? Is there, in any case, something inherently wrong with the genetic modification of crops or cattle, different
in kind from the taking of cuttings or the selective breed-ing that has been part of horticulture and agriculture for ages past? Is the manipulation of human genes to prevent
a child’s being born with a devastating monogenetic dis-ease, such as Tay-Sachs’s disease or Duchenne’s Muscular Distrophy, different in kind from surgical intervention, or intervention by drugs, which doctors have always prac-tised in pursuit of their professional goal to alleviate suf-fering? Some regard genetic intervention as uniquely sinister; it is thought to contravene the laws of nature by artificially speeding up the kinds of changes properly brought about by the slow processes of evolution and nat-ural selection Debate about what is or is not ‘natnat-ural’ is curiously emotive Part of the work of bioethics is to analyse and evaluate such appeals to Nature
Of particular importance at the beginning of the twenty-first century have been the questions raised about embryonic stem cell research, or therapeutic cloning This
is a process by which embryos are produced, not by nor-mal conception, the fertilization of fenor-male eggs by nor-male sperm, but by cell nuclear transfer, where the nucleus of
an egg is removed and replaced by that of another; after the application of an electric current, the egg with its new nucleus can develop into an embryo This is the first part
bioethics 95
Trang 7of the process of cloning a whole animal, or reproductive
cloning If a whole animal is to be reproduced, the newly
formed embryo is placed in the uterus of a surrogate
ani-mal and brought to term Thus Dolly the sheep was
cloned at the end of the twentieth century But the
pur-pose of therapeutic cloning would be frustrated if an
embryo were allowed to develop beyond its very first
stages For at the beginning of its life the cells of the
embryo are ‘totipotent’; that is, each may develop in any
direction, to become any of the 120 or so types of cell that
make up the body, or indeed may become part not of the
embryo itself, but of the placenta or umbilical cord The
purpose of the research is to discover how to direct these
cells (embryonic stem cells) to develop in specific ways, to
become, let us say, cells belonging to the spinal cord, or
the brain, or the skin The ultimate aim is to produce
banks of cells of particular types that may be used for cell
transplant rather than whole organ transplant This would
have enormous advantages, in that parts of the body,
including the brain, could receive transplants, and
dam-aged cells would renew themselves permanently All this
is far in the future; but the possible ethical objections to
such procedures, especially centred on the fact that
embryos would be created and then destroyed when their
use was over, are already among the issues to be argued by
bioethicists
In fact, at the core of much of their philosophical
con-cern is the status that should be accorded to the human
embryo In the UK human embryos may be used for
research up to fourteen days after their creation (whether
by fertilization etc or by nuclear transfer) The Human
Fertilization and Embryology Act (1990) enshrined that
principle in law At that time, embryos might be used only
for research into issues concerned with fertility, infertility,
and contraception Later, regulations were introduced
through Parliament which permitted their use in research
into therapeutic cloning, but the fourteen-day limit
remained The reason for this cut-off point was
physio-logical Until fourteen or fifteen days from the beginning of
its life, the embryo, however it was brought into being, has
no vestige of a central nervous system, and therefore can
have no conscious experiences of any kind It is impossible
to cause such an embryo pain Though its genetic identity
has been fixed, it cannot be regarded as an individual person;
indeed, it may yet divide and become twins or quadruplets
Using it for research is therefore more akin to using human
tissue than using a child or an adult experimentally
Such considerations fell, and still fall, to be considered
by bioethicists For despite the largely evidence-based
arguments of those who supported the 1990 law, there are
many people who dispute the moral acceptability of the
law, and would like to see it changed so that from the
moment it comes into existence an embryo is protected
from being used for research and then destroyed These
people uphold the principle of the sanctity of human life,
at all its stages
This principle is strongly supported by most members
of the Roman Catholic Church, and this partly explains
the difference, on bioethical issues, between different countries, within Europe and beyond There was a period when the Roman Catholic Church, following Thomas Aquinas (himself following Aristotle), held that a human foetus becomes a full human being, acquiring a soul, at about forty or ninety days from conception, depending on its gender However, in the nineteenth century the Church decided, rightly, that there could be no certainty about when the soul entered the body, and that therefore even the earliest embryo should be given the benefit of the doubt It was therefore deemed that immediately after conception the embryo had, or probably had, a soul, and was effectively a human person, so that to destroy it was murder
Against this there is the argument put forward by, among others, John Habgood, an eminent bioethicist, a biologist turned churchman who became archbishop of York, which holds that we must, as post-Darwinians, take
a developmental view of the human embryo, as we do of the human race itself There is no one moment when the human person springs into existence The further the col-lection of cells which forms the human embryo develops, the more we are properly inclined to accord it the status of
a person, and the higher the value we attach to its life and life-chances It was such arguments as these that prevailed
in the UK in 1990 But the arguments continue, and the issue still dominates bioethics in at least one of its branches
Questions raised by the new techniques do not depend
on wholly new moral principles But they involve apply-ing moral principles to sometimes wholly new possibil-ities; and this in turn involves taking a newly long-term view of possible consequences for society How would it
be if people could choose the sex of their babies, or, more startling, choose to alter their genetic make-up before birth? Could society tolerate a world in which the mixture
of genes a child was born with was no longer a matter of chance but could be ‘designed’ deliberately? What, if any,
is the fundamental moral objection to the cloning of human beings, supposing such a thing were ever to become safe enough to try? Such questions, which used to
be strictly a matter of science fiction, now seem nearer
to reality, and it is the fear of such a reality that causes bioethicists to be in increasing demand Their task is to help people to think clearly about how, in the light of our new knowledge, we value, or ought to value, life in all its form, and at all stages of development m.warn

biological naturalism.The view that mental phenomena such as *consciousness and *intentionality are natural
bio-96 bioethics
Trang 8logical phenomena on a par with growth, digestion, or
photosynthesis Biological naturalism is defined by two
main theses: (1) all mental phenomena from pains, tickles,
and itches to the most abstruse thoughts are caused by
lower-level neurobiological processes in the brain; (2)
mental phenomena are higher-level features of the brain
Mental phenomena are thus ‘emergent’ in the sense
that they are causally explained by the behaviour of
lower-level elements which do not in themselves individually
have these features Thus, according to biological
natural-ism, the brain is conscious and consciousness is caused by
the behaviour of lower-level elements such as neurons
even though no single neuron is conscious Formally
speaking, relations of this sort are common and
unmysterious in nature For example, a whole system can
be in a liquid state, and the liquid behaviour can be caused
by the behaviour of the molecules even though no single
molecule is liquid Biological naturalism does not deny
that alternative forms of chemistry might be able to cause
consciousness but insists that since mental phenomena
are in fact caused by brain processes any other system that
caused mental phenomena would have to have causal

biology, philosophical problems of.The most
distinct-ive feature of biology, from a philosophical point of view,
is its characteristic use of functional or *teleological
explan-ations These are explanations in which some biological
trait is explained by showing how it is useful for the
organ-ism in question For example, the function of the polar
bear’s white fur is to camouflage it; the function of human
sweating is to lower body temperature; and so on The
philosophically interesting aspect of these explanations is
their apparent commitment to teleology: they seem to
explain items (the whiteness, the sweating) in terms of
their consequences (the camouflage, the cooling) By
con-trast, normal causal explanations run in the other
direc-tion, and account for consequences in terms of their
causes
Until fairly recently most philosophers of biology took
these explanations at face value, and argued that the parts
of integrated systems, like biological organisms, can
legit-imately be explained in terms of their contribution to the
well-being of the whole In particular, Carl Hempel
argued that such explanations were a subspecies of
cover-ing-law explanations This approach is now widely
rejected, however Most contemporary philosophers of
biology now hold that functional explanations in biology
are in fact disguised causal explanations, which explain
biological traits not by looking forward to future beneficial
results, but by looking backwards to the past evolutionary
his-tories in which such results led to the natural selection
of the traits in question Thus the functional explanation
of the polar bear’s whiteness does not refer to the future camouflaging of the bears, but to the fact that their past camouflaging led to the natural selection of their whiteness
The centrality of the Darwinian theory of *evolution by natural selection to biological thinking raises a number of further philosophical issues An initial question is whether the theory has any real predictive content, or whether the thesis of ‘the survival of the fittest’ simply collapses into the empty truism that ‘whatever survives, survives’ However, there are ways of formulating the theory so that
‘fit’ acquires a meaning which is independent of survival
A related charge is ‘adaptationism’: does not the theory
of evolution by natural selection simply invent evolution-ary ‘just so stories’ in order to portray all biological traits as having some selective benefit? In response, supporters of the theory will admit that some biological traits are acci-dents that serve no function, but will insist that there is genuine evidence to show that many other traits have been selected because of their effects, and that this process
of selection has been crucial to the evolution of species
At a more detailed level, there is controversy about which ‘units of selection’ are involved in Darwinian processes Should we think of natural selection as operat-ing primarily on groups, or individuals, or genes? Some progress with this knotty issue has been made by distin-guishing ‘replicators’, in the form of the genes which embody the lasting effects of selection, from ‘vehicles’, such as individuals and groups, whose survival is usually the prerequisite for gene survival
Work on the logic of natural selection has led to the development of sociobiology, which seeks to understand animal social behaviour as the genetically based product
of natural selection Critics of sociobiology object that much behaviour is non-genetic, especially in higher ani-mals and humans Some sociobiologists deny this claim Others respond that, even if environmental influences on behaviour are also important, it is still valuable to under-stand the evolutionary pressures on those genes which do affect behaviour
Biology, along with other special sciences like psychol-ogy, geolpsychol-ogy, meteorolpsychol-ogy, and so on, raises the issue of
*reductionism Most contemporary philosophers of biol-ogy are reductionists at least to the extent of denying ‘vital spirits’ or other emergent biological substances, and accepting the *supervenience of biological properties on physical properties Far fewer, however, are reductionists in the stricter sense of believing that all biological laws can be explained by physical laws Instead they hold that there are
sui generis biological laws, patterns which are common to
biological systems with different physical make-ups, and which therefore cannot be explained in terms of physical

black box.A black box is a system whose internal
work-ings are unknown or irrelevant to current purposes The
computer model of the mind treats the mind as a system
that itself is composed of interacting systems, which
themselves may be composed of further interacting
sys-tems, and so on The bottom-level primitive processors,
the black boxes that cognitive science leaves unopened,
are understood behaviouristically: what they do (their
input–output function) is in the domain of cognitive
sci-ence, but how they do it is not (How they do it is in the
domain of electronics or neurophysiology, etc.) Via the
hierarchy of systems, cognitive science explains
intelli-gence, by reducing the capacities of an intelligent system
to the interactions among the capacities of unintelligent systems, grounded in the bottom-level black boxes But the model does not explain *intentionality in this way since the bottom-level black boxes are themselves

Blackburn, Simon(1944– ) Professor at Cambridge, for-merly at Oxford and North Carolina, known for his defence of *quasi-realism about items whose reality has been much disputed—e.g values, causes, numbers As to values, he argues that the impact of the perceived world
on the mind, together with the beliefs formed thereby, generate habits, emotions, sentiments, and attitudes which come to be projected on to the world and to be regarded as real properties of that world; so commitments
of approval or disapproval become judgements with truth-values And rightly so, for values supervene on nat-ural properties Thus, such judgements are neither mere expressions of subjective sentiments nor truths which obtain independently of human attitudes And we should
be neither anti-realist nor realist about values; the right stance is quasi-realism Blackburn has also published a
suc-cessful popular introduction to philosophy, Think (1999).

black philosophytoday takes two principal forms In one form, it is a hermeneutic enterprise, offering explications, interpretations, and exploitations of the traditional wis-dom of African societies through the concepts and termi-nology of contemporary Western philosophy The topics typically include the general nature of being, the numin-ous, the nature of human society and the place of human beings in it, causality and agency, and action An offshoot
of this instead exploits insights and nuances available in
African languages to enrich philosophical analyses of
con-cepts dealt with in Western philosophy In its other form, black philosophy employs the analytical tools of contem-porary philosophizing in order to characterize the social history and problems of peoples of African descent to the extent that these are either peculiar to their experience or peculiarly exacerbated in their experience
The first form is enmeshed in a vigorous debate about the proper classification of the material, and in conse-quence its possible usefulness One camp proposes to treat
it as no more than ethnographic material, invaluable in clarifying self-concepts of Africans This camp, notwith-standing the practice of elders gathering in conversation, regards the material a priori as lacking in individual
98 biology, philosophical problems of
Trang 10contributions or modifications and critical debate,
prin-cipally because it was originally unscripted; for this camp
proposes scripted authorship and critical debate as sine qua
non tests for the rubric of philosophy It describes the
hermeneutic account as ethnophilosophy.
A second camp postulates that the tradition is an
evolv-ing result of the collaboration of individual elders whose
discussions and debates are submerged, by the nature of
the case, in the tenets of the oral tradition It is noted that,
even in the case of the literate early Pythagoreans, critical
debate does not appear to have been permitted, and it
remains a highly speculative thing to impute a specific
view to any of them Indeed, all their accepted views seem
to have been ascribed to Pythagoras himself, even well
after his death, irrespective of their actual source
In fact, the idea of philosophy, like that of any discipline,
is quite variable, and there is hardly ever a single
overrid-ing paradigm sufficiently protean to fit philosophy or any
other discipline at every stage in its history For example,
much of what is admired today as ancient Greek
philoso-phy does not satisfy contemporary notions of philosophiloso-phy,
and some did not satisfy even Aristotle’s! It would be
equally pointless to try to bring the diversity of today’s
philosophical practices under a single paradigm
A broader view can discern philosophy at different
points in its evolutionary tree, and can penetrate the
den-sity of the idiom of African philosophy and recognize the
philosophical aspects of its preoccupation and content,
and thereby avoid the superficiality of an inflexible
equa-tion of idiom with myth It thus becomes clear, for example,
that of two West African peoples, the Diola proposed
corporeally expressed force as a cosmological principle,
denied it a temporal beginning, and made it inexhaustible,
indestructible, and all-encompassing General quantitative
variations in it were taken to express its creative energy,
and the actualizations of these variations constitute the
diversity of natural forms Different orders of being come
about through a progressive lessening in its
expressive-ness By contrast, the celebrated Dogon people postulated
an extremely dense body for their cosmological principle,
and, by appeal to concepts of prefiguration and specific
motions, sought to explain principal and determinative
categories of nature, the four elemental natural masses of
air, fire, water, and earth, as well as consciousness and
human society, etc Data like the above enjoy a cultural
and historical centrality, but their hermeneutic
explica-tion and its tools are transcultural and transhistorical In its
variety of versions, the above kind of black philosophy (or
African philosophy) is today supported by a rapidly
grow-ing literature
The other form of black philosophy is an independent
movement and not a direct development from African
philosophy It is the more vigorous, the more fully
estab-lished, and the clearer in its aims and methods It is centred
in the United States Avoiding metaphysical issues, it
con-centrates on the development of normative concepts of
the identity and emancipation beyond sheer liberty of the
black peoples of the Americas and on strategies for their
application towards social reconstruction of American societies Issues of race and moral attitudes and actions become dominant in it The discussion of race, however,
is, only now overcoming a remarkable denial of the reality
of race which merely confused the factitious with the ficti-tious This form of black philosophy uses techniques of
analytical philosophy to re-cluster and redefine concepts relating to issues of social identity, social and economic emancipation and justice, and relations between cultures
It uses the re-clustered and redefined concepts to direct the critique of phenomena relating to them It calls to its aid the categories and syntheses of the European contin-ental tradition in philosophy in the endeavour to develop and illuminate strategies for the existential grounding
of historical readings and the elimination of reifying processes and bad faith in the continuance of racist displays
It has reinvigorated its topics by making the black experience salient as a modifier of the intuitions, ideals, common sense, and persuasiveness of argumentation in the social and normative domain In this way, it has shed considerable light on its topics, especially those of social discrimination, affirmative action, and the underclass Its intention, however, is not the mere clarification of con-cepts, but the promotion of emancipation beyond liberty
