partly in England as a Rhodes Scholar, who defended
*rationalism and *idealism during an era in which they
had few defenders He taught at the University of
Mich-igan, Swarthmore, Columbia, and for most of his career at
Yale University He argued against the doctrine of Hume
that causation is merely the constant conjunction of
events and the view of *Logical Positivism that a priori
statements are merely consequences of linguistic
conven-tions There are, Blanshard said, genuine ‘necessary
con-nections’ in the world A naturalist in ethics, Blanshard
held that ‘to call an experience intrinsically good is to say
that it is fulfilling and satisfying’ Since he granted ‘that the
word “good” has [in addition] an aura of emotional and
associative meaning’, he could ‘keep emotive meaning
and also keep it in its place’ A naturalist in religion too, he
took ‘the service of reason’ as his religion ‘That service
calls for the use of one’s reason to embrace as much as one
can of the reason implicit in the universe, and its use at the
same time to define and harmonize the ends of practical
life.’ Blanshard’s personal demeanour was one of

body.One of the most fundamental concepts in
philoso-phy because of the role it plays in the picture of an
‘exter-nal world’ composed of three-dimensio‘exter-nal entities which
we perceive Generally contrasted in this sense with space,
the medium containing these entities, bodies are also
con-trasted with minds (except in the thinking of materialists
like Hobbes) because the external world containing
bod-ies is not external to my own body; it is rather that my
body is itself one of them Once this picture holds sway,
two great problems emerge One is that, if my knowledge
of reality is confined to my own perceptions, how can I be
certain what the world is really like, or even that it exists at
all? Almost all the great philosophers have regarded these
as difficult questions, some concluding that there is no
external world, some that we can’t know what it is like
This is not surprising: given the picture of perceptual
experience which generates such questions, they are
unanswerable If my perceptions are private mental
phenomena, the gap between them and the ‘physical’
world is unbridgeable
The other great problem is that I appear in this scheme
of things to have a special and peculiar relationship with
one of the entities in the physical world, which is my body
But it is difficult to say why I believe, as it is generally
claimed I do, that it belongs to me Descartes was inclined
to think that I regard it as mine because it always
accom-panies me, which might be called the ‘stray dog’
concep-tion of ownership It ought to be clear, however, that any
such account is confused: it relies on describing me, and
where I am, in terms that are ruled out by the picture
which generates the problem If I am, as Descartes
thought, a mind, a non-spatial entity, it makes no sense to
say where I am, and hence no sense to suggest that my body might be in the same place or close by
Both these alleged problems, then, have tormented philosophers endlessly precisely because they are gener-ated by a metaphysical picture which makes them

Bohr, Niels (1885–1962) Danish physicist and Nobel

to atomic theory and nuclear physics (the liquid drop
model) and, indirectly, influenced the rise of molecular
biology Much to his surprise he found that his early
(1910) belief that experience is basically ambiguous was
supported by ‘hard and solid’ scientific evidence: concepts
firmly grounded in facts divide into mutually exclusive
or ‘complementary’ groups all of which are needed for
stating what we know, though the use of any particular
group rules out the use of the rest According to Bohr
different cultures, different concepts or attitudes within
a particular culture (truth and clarity, love and justice),
and different methodological approaches (mechanicism
and teleology in the life sciences) are related in a similar
way Bohr believed that the problems created by the
paradoxical status of human beings—they are part of the
world and yet put themselves outside of it when claiming
to possess knowledge—are resolved by using

Boolean algebra.A simple and elegant type of algebraic
structure In 1847 George Boole gave the structure its first
unrefined description as part of his development of an
algebra of logic His aim was to translate sentences
expressing logical relations into algebraic equations which
were then to be manipulated according to algebraic laws
to determine what can be deduced from the original
sen-tences The algebraic laws can be thought of as axioms
governing the operations they mention Boole saw that
the axioms do not have a unique subject matter but rather
characterize a type of structure This generalizing move
enabled the Boolean structure to be discerned in a wide
variety of domains; for example, there are Boolean
alge-bras of propositions, sets, and switching-circuits
In formal terms, a Boolean algebra is a structure
con-taining a set B, two binary functions (intersection or
meet) and ∨(union or join) on B, one unary function '
(complementation) on B, and two distinguished elements
0 (the null-element) and 1 (the unit-element) of B, satisfy-ing the followsatisfy-ing axioms, for all x, y, z∈B:
1 x∨( y∨z) = (x y)∨z and x ( y z) = (x y) z.
2 x∨y = y∨x and x y = y x.
3 x∨( y z) = (x∨y) (x∨z) and x ( y∨z) = (x y)∨(x z).
4 x∨x' = 1 and x x' = 0.
5 x∨0 = x and x 1 = x.
A binary relation ≤on B is defined as x≤y↔x y = x;

Bosanquet, Bernard (1848–1923) British philosopher who, influenced by T H Green, was, along with F H Bradley, one of the chief promoters of Hegelian, or absolute, *idealism in late nineteenth-century England
He taught for a while at Oxford (and more briefly later at
St Andrews) but spent most of his life as a writer and engaged in the politics of charity Less sceptical and more purely Hegelian than Bradley, he wrote on metaphysics
and logic: Knowledge and Reality (1885); Logic; or, The Morph-ology of Knowledge (1888) Probably his best work is The Philosophical Theory of the State (1899; 4 edns.; frequently
repr.) In it he identifies the individual’s real will with the state and hence holds that ‘the common self or moral per-son of society is more real than the apparent individual’ Given this great importance of the state as ‘the fly-wheel
of our life’, he easily constructs a retributive theory of pun-ishment in which punpun-ishment is someone’s ‘right, of which he must not be defrauded’ r.h

phe-nomenological reduction According to Husserl, and some
of his followers, we can describe the objects of our minds as
phenomena only after we have bracketed their existence By
bracketing the objective world, one suspends judgement
about the existence of the things around us The botanist, for
example, takes for granted that there are trees and studies
their characteristics The phenomenologist does not deny
that the botanist is right, but he puts the existence
assump-tion in brackets, and tries to describe the phenomena
pre-cisely as they present themselves to him For example, the
phenomenologist may study the object of a mental act of
seeing a tree, the precise what of what he is seeing at that
moment, irrespective of whether his perception is correct,
of whether there are trees, or even of whether there are any

philoso-pher, fellow of Merton College, Oxford Bradley is indis-putably the greatest British philosopher between J S Mill and Bertrand Russell His philosophy is a late example of the movement of British philosophers away from the trad-ition of British *empiricism towards German *idealism,
in particular Hegel However, despite himself, he was much nearer to British Empiricism than other British idealists of the period such as T H Green and Bernard Bosanquet
Ethical Studies (1876) was his most Hegelian work
Con-tending that a moral outlook must be justified by the form
of ‘self-realization’ it offers, Bradley examines a series
of moral systems which in turn rectify each other’s contradictions
*Hedonism, whether individualist or universalist, pre-sents itself initially as the most attractively down to earth
of moral theories But the maximization of pleasure pro-vides no genuine form of self-realization for anyone The pleasures of different times form no real totality, since they never exist together, and can never constitute a state
of affairs of which anyone can say: ‘Here I have that which
I was seeking’
Bradley now turns to the sharply opposed Kantian ideal
of ‘duty for duty’s sake’ Here the good is identified with sheer rationality; one is to behave only in a way which one could will universalized without contradiction This advances on hedo-nism in recognizing the self as somehow
a ‘universal’ rather than as a series of ‘perishing particu-lars’ But its purely formal notion of morality provides nei-ther a definite guide nor any proper human satisfaction Next comes the vastly superior Hegelian morality of
‘my station and its duties’ Here the demands of morality are no longer those of a remote logical abstraction, with
no appeal for flesh and blood, but those of a role in a con-crete historical community such as provides a satisfying life for the real empirical man Much more satisfactory as
is this social ethic than the two preceding, it cannot be the final truth For the community itself may be rotten with a morality to be transcended; moreover, full self-realization need not be purely social
These limitations push us on to what Bradley calls ‘ideal morality’ The basic injunction here is to realize every-where the best self, and our idea of our best self, though it must arise from the ideals we learn in the family and in life
in the community, may develop beyond it to take account
of values learnt from other societies or based on internal criticisms of our own society The basic test for the adequacy of an ideal morality is that it satisfies the indi-vidual as a ‘concrete universal’, that is as an indiindi-vidual whose life is a unity, resting on his unity with his kind, rather than, like the other three theories respectively, as a mere series of experiences, or as some abstract pure ego,
or as being entirely socially conditioned
In his next great work, The Principles of Logic (1883), the
Empiricists’ psychologistic approach to logic is criticized
in a manner not unlike Husserl, but, like Husserl, he includes the examination of strictly necessary features of
104 bourgeoisie and proletariat
Trang 6thinking within its remit A main theme is the
inadequa-cies of the traditional Aristotelian analysis of judgements
into subject and predicate There are many propositions
(e.g existential and relational ones) and related forms of
inference which escape this net
Ultimately every judgement ascribes a single (normally
complex) idea as predicate to Reality as subject Reality is
that greater whole of which the perceptual manifold
pre-sents itself as an incomplete fragment There are
intri-guing similarities and contrasts between Bradley’s position
here and that of Bertrand Russell, whose theory of definite
*descriptions (talking of the King of France where Bradley
talks of the King of Utopia) as belonging logically to the
predicate owes somewhat to him, as does his account of
existential (also universal) propositions For Russell the
most basic factual propositions concern particulars with
which we are acquainted; those whose grammatical
sub-jects are only identified by description are logically
deriva-tive Bradley is even more insistent that it is only because
our access to Reality is not entirely conceptual that we get
beyond the circle of our own ideas in thought and treats
demonstratives quite similarly, though holding that they
must be dropped in fundamental theory
*Inference is the construction of a larger mental
repre-sentation put together from those which constitute the
premisses, and reading off a conclusion from the holistic
character it turns out to possess (oddly anticipative,
though without any whiff of materialism, of suggestions
by some current ‘cognitive scientists’)
Appearance and Reality (1893) is the main statement of
his metaphysics Book i,Appearance, argues that most
ordin-ary things (e.g things and their qualities, time and space,
causation, the self, even things-in-themselves) are merely
appearances, while book ii, Reality, strains to characterize,
with more final truth, the Reality they so usefully
mis-represent to us, namely the *Absolute, a single cosmic
experience of which we (so far as we truly are at all) are
components
In calling something an appearance Bradley means,
pri-marily, that the concept of it only gives a pragmatically
useful way of thinking about some aspect of the world of
which, being incoherent, it cannot give us a finally
satis-factory grasp Something in the Absolute, for example,
corresponds to Time, but it is so unlike Time, as we
ordin-arily conceive it, that thus conceived it is ultimately an
illusion However, reality (as predicate) is a matter of
degree, that is, our concepts are true (and conversely false)
of reality (as thing) in different degrees The concept of the
Absolute is more adequate than that of *time, but both are
just our way of grappling with what the intellect cannot
finally grasp This is established by two main lines of
argu-ment, firstly, that reality must have a unitary togetherness
which cannot be captured by the ordinary conception of
many distinct things in relation, secondly, that all concrete
reality must somehow be psychical in its nature Reality is
somehow one vast eternal self-experiencing many-in-one
Though often presented somewhat sophistically, there is
a vein of powerful argument to back this conclusion up
The most famous feature of the first line of argument is his attempt to show that the idea that the world consists in
a multiplicity of distinct things standing in various rela-tions to each other is incoherent For when two terms stand in a certain relation, we must either think of the rela-tion as a separable component in the total state of affairs or
in some other way (1) If you think of it as some kind of
separable component, then it seems to require to be related
to its terms by fresh relations, and these to be related to those relations and their terms by further ones, and so on
in an impossible regress (2) To avoid this you may treat the relation as an aspect of one or other of the terms, or divide it into two aspects one pertaining to each of the terms But in either case the terms are apparently left apart, each simply possessing a feature which does not bring it together with the other one (3) Finally, you may treat the relation as an aspect of the terms taken together as constituting a unit But that betrays the very notion of a relation by merging the terms between which they hold into a single thing; moreover, their togetherness does not seem particularly due to the rela-tion since they have already (logically speaking) to be together to provide a home for it In effect, Bradley’s pos-ition is that relational thought allows us to shift between thinking of a thing as something conceivable independ-ently of how it stands to other things and thinking of it as
a mere aspect of some larger whole they jointly help to constitute, two ways of conceiving it which militate against each other
Bradley’s solution is that for one thing to be (as we would ordinarily somewhat distortingly put it) related to another is
in the end always a matter of their being aspects of some more comprehensive and more genuinely concrete individ-ual, conceived apart from which they are necessarily to some extent misconceived If so, and since everything is somehow related (as we would ordinarily put it) to every-thing else, there must be some maximally comprehensive and concrete individual (the Absolute) from which every-thing else is an abstraction
That this ultimate individual must be a single cosmic experience including everything is established by the sec-ond line of argument according to which we can form no genuine conception of an unexperienced reality An appli-cation of this principle at the level of finite existence shows that it consists ultimately of myriad finite centres of experience and their presentations on the basis of which they construct the world of common sense, while the monistic argument shows that these centres must pertain
to a Whole conceived apart from which they are partly misconceived
In some respects his form of absolute idealism receives a
better presentation in his Essays on Truth and Reality (1914).
This also contains the classic statement of a *coherence theory of truth and knowledge His contention that there are no basic judgements beyond revision, and that the whole system of our thought continually faces experi-ence as a whole, has strong affinities with aspects of the work of W V Quine Nicholas Rescher has derived much

brain in a vat.Contemporary counterpart of Descartes’s
hypothesis that one’s beliefs are induced by an evil genius
Used within a premiss in arguments for scepticism, the
hypothesis says that nothing exists except one’s brain—in
a vat, in order that its electrochemical activity should be
sustained—so that whatever may seem to one to be the
case, its seeming so is accounted for by such activity alone
The sceptic invites one to say ‘For all I know, I am a brain
in a vat, and there is no external world’
Brains in vats are introduced also in philosophy of mind
in connection with the idea that a person’s psychological
faculties require nothing but a brain’s operations The idea
may be questioned, and will be by the supporters of

Brentano, Franz(1838–1917) German philosopher edu-cated at Würzburg, Munich, Berlin, and Münster Univer-sities He was awarded his Ph.D at Tübingen University
in absentia in 1862 Two years later he was ordained a
priest In 1866 he wrote his habilitation thesis and was
appointed Privatdozent at the University of Würzburg His best-known book, Psychology from an Empirical Standpoint
(tr London, 1973), appeared first in Leipzig, in 1874 Brentano was called the same year to the University of Vienna as full Professor of Philosophy After he left the Catholic Church and got married in 1879 he had to resign
the professorship, but continued to serve as Privatdozent at
Vienna University until 1894 He spent the following years mostly in Florence, and finally in Zurich, where
he died
The Background: The Philosophy of Aristotle Franz Brentano’s
work was inspired by the philosophy of Aristotle, whom he regarded as a ‘man for all times’ Much of Brentano’s work, although critical in spirit, is dedicated to Aristotelian issues
His doctoral dissertation The Several Senses of Being in Aris-totle (Freiburg im Breisgau, 1862; tr Berkeley, Calif., 1981) and his habilitation thesis on The Psychology of Aristotle
(Mainz, 1867; tr Berkeley, Calif., 1977) focus on Brentano’s chief preoccupations, psychology and *ontology Brentano also investigates these topics in his lectures on metaphysics which began in 1867
Metaphysics, says Brentano, in order to be established
as a strict science, has first to seek for a basis in certainty Scientific knowledge has to show itself either as evi-dent, and therefore true, or at least as highly probable Immediately evident thoughts, for Brentano, are the
‘Archimedean points’ of all our knowledge and arguments,
and of all sciences (The True and the Evident (tr London,
1966)) Secondly, metaphysics has to deal with ontological
questions, (a) in a narrow sense, where it is *‘phenom-enology of mind’, and (b) in a wider sense, where it is
the ontology of things other than ourselves: the world,
God (On the Existence of God (tr The Hague, 1987)), the
cosmos
106 Bradley, F H.
Trang 8The Ontology of Mind: Psychology and Phenomenology.
Brentano’s psychology starts from an empirical standpoint
Empirical psychology, in his view, is to be defined as the
science of inner experience or awareness This conscious
awareness, considered in itself, presents itself as being
(a) intentionally related to external entities, and (b)
reflex-ively related to itself Brentano analyses both relations in
order to describe the ultimate elements of the experienced,
intentional structure of the mind This he does in his theory
of *intentionality He sets out to analyse the epistemic
sta-tus of these phenomena in his Descriptive Psychology
(Ham-burg, 1982; tr London, 1994), which he also called
‘descriptive phenomenology’ or ‘phenomenognosis’ His
aim is ‘to define the elements of the human consciousness
and of their interconnections (as far as possible) in an
exhaustive manner, in order to give us a general notion of
the entire human consciousness’ (ibid 1–2) Brentano gives
a ‘pure description’ of the facts of consciousness, rather
than a consideration of the physiological genesis of our
conscious phenomena, since such a genetic psychology
must rest on a descriptive psychology In order to give a
complete description (‘microscopic analysis’) of the
phe-nomena of the human mind, philosophical psychology
must first and foremost examine ‘mental phenomena’,
‘functions’, or ‘acts’ (The Psychology of Aristotle and
Psych-ology from an Empirical Standpoint) Thus Brentano became
known as the founder of ‘act psychology’
All the data of our consciousness, according to
Brentano, are divided into two classes: the class of physical
phenomena and the class of mental phenomena A mental
phenomenon is, for instance,
[e]very idea or presentation which we acquire either through
sense perception or imagination By presentation I do not
mean that which is presented, but rather the act of presentation
Furthermore, every judgement is a mental phenomenon
Also to be included under this term is every emotion the term
‘mental phenomena’ applies to presentations as well as to all the
phenomena which are based upon presentations This act of
presentation forms the foundation not merely of the act of
judg-ing but also of desirjudg-ing and of every other mental act Nothjudg-ing can
be judged, desired, hoped or feared, unless one has a presentation
of that thing Examples of physical phenomena, on the other
hand, are a color, a figure, a landscape which I see; a chord which
I hear; warmth, cold, odor which I sense; as well as similar images
which appear in the imagination (Psychology from an Empirical
Standpoint, 78–80)
The characteristic common positive property of each
mental phenomenon is what was
called the intentional (or mental) inexistence of an object, and
what we might call, though not wholly unambiguously,
refer-ence to a content, direction towards an object (which is not to be
understood here as meaning a thing), or immanent objectivity
We can therefore define mental phenomena by saying that
they are those phenomena which contain an object intentionally
within themselves (Ibid 88–9.)
The characteristics of mental phenomena stated by
Brentano here and elsewhere can be summarized under
three headings
1 There are three classes of them: presentations, judge-ments, and emotive phenomena They are either acts of presenting which serve as a basis for all other mental acts, i.e these other acts necessarily contain presentations as
‘parts’ and are dependent on presentations, which are the
‘fundaments’ or ‘motifs’ for the other ‘superposed’ acts This implies that the science of judgements, i.e logic
(The Theory of Correct Judgement; German edn Die Lehre vom richtigen Urteil (Bern, 1956) ), and the science of emotive phenomena, i.e ethics (The Origin of Our Know-ledge of Right and Wrong (tr Westminster, 1902; repr London, 1969); The Foundation and Construction of Ethics (tr London, 1973) ), relies on fundamental psychological
observations of modes of presentations In a correct judge-ment, some presentation, or a part of it, is either affirmed
or denied if the categories true or false are evidently applicable Analogously, in a correct act of emotion, something is either loved or hated correctly, or preferred correctly, motivated by the goodness of what is presented Yet acts of judgements and of emotions differ
funda-mentally from acts of presentation (a) because there is
no inner difference in presentations—they are all positive;
(b) because a judgement as well as an act of emotion is not
just a connection or separation of presentations but an additional judging or emotive act, respectively, on the ground of what is presented
2 Mental phenomena (a) are or have an intentional
relation towards a ‘content’ (a thought) or an ‘immanent
object’ (an object thought of ); (b) are conscious and
reflexive mental acts To any conscious act there essen-tially belongs a relation And as in any relation, there are two inseparable correlates The one correlate is the conscious mental act itself (the ‘fundament’ of a relation), the other correlate is that (the ‘terminus’ of a relation)
to which it is directed The conscious act is always the real correlate; that about which it thinks is not necessarily
a real adjunct of the act of thinking I may think about
a unicorn as my thought content My thinking about
it is real, the unicorn is not It is a thinker who has mental phenomena or properties: only individuals, per-sons, can have psychical properties Structures or abstract systems cannot have them If a psychical state is to
be exemplified, then it can be exemplified only in an individual
3 Mental phenomena show a ‘twofold energy’ Each act, whilst directed towards something, at the same time and in passing is reflexively directed towards itself Being presented with a physical or ‘primary’ object, e.g a sound,
we are aware of being presented with it In a mental phenomenon as such, the consciousness of itself, the
‘secondary object of perception’, is included This ‘sec-ondary inner perception’ is a true, self-referential, evident perception in the strict sense When an intentional phe-nomenon occurs to us, we know that it occurs; and in knowing this we grasp its essential nature When we judge, we know what the property of judging is and what is logically required if an individual is to have such a property
Brentano, Franz 107
Trang 9Ontology of Things In his philosophy of mind, or
psychology, Brentano deals mainly with inner experience
and sets aside the objects of outer experience
In the metaphysical context, he argues for the value and
the validity of our mediate, indirect knowledge of bodily
substances and their properties, with properties of all
beings, of God and the world This ontology in the
broader sense presupposes the ontology of mind, which
thus forms a foundational, integral part of the ontology of
things So, as the phenomena of human consciousness
essentially are characterized as being ‘intentionally
directed’, the ‘outer world’ analogously is seen as
charac-terized by its teleological structure
In his description of mental phenomena and their
struc-tural interrelation Brentano aims at a ‘microscopic’
analy-sis, as remarked earlier, but in his macroscopic cosmology
he sees ‘the whole as end of the parts’ His ontology of
things develops what he had envisaged in his doctoral
dis-sertation, where he attempted a description of Aristotle’s
theory of categories Brentano differentiates the
cat-egories into (1) objective (‘reelle’) concepts of the kinds
(genera) of being, and (2) semantic (‘logische’) modes
(predicaments) of speaking about being This
differenti-ation is to be seen not as a fundamental discrepancy, but as
a change of aspects in a description theory of being
Brentano goes on to emphasize that only real things, ‘res’,
or individuals, not concepts of things, or universals, are
the proper objects of description
Brentano’s Influence Brentano’s empirically motivated
philosophy was designed in analogy to the method of
nat-ural science: ‘The adequate method of philosophy is that
of natural science.’ This was the thesis of his habilitation
colloquium and Carl Stumpf, who was then studying
under Brentano, reports that it attracted many students to
him Among them were Stumpf himself, known for his
Tonpsychologie; Anton Marty (and students of his in the
Prague Linguistic Circle, such as Franz Kafka and Max
Brod), known for his descriptive philosophy of language;
Sigmund Freud; the ‘Graz School’ around Alexius
Meinong, known for its ‘object theory’; Christian von
Ehrenfels, for his ‘Gestalt theory’; Edmund Husserl, for his
phenomenology; Tadeusz Kotarbinski, for his ‘reism’;
Thomas G Masaryk, for his ‘concretism’; George F Stout
and his students Bertrand Russell and G E Moore; the
Würzburg School centred around Oswald Külpe, known
for its experimental psychology of thinking; Max Scheler,
known for his ethics; and Martin Heidegger Quite a
num-ber of more recent influential thinkers, such as Roderick
M Chisholm, admit Brentano’s influence, and there is
good reason to call him the ‘grandfather of
phenomen-ology’ (Gilbert Ryle) and ‘terminus a quo of Austrian

Bridgman, Percy William(1882–1962) Distinguished as a physicist, Bridgman has had considerable impact on the philosophy of science in the twentieth century, with his insistence that the work and results of science, especially physics, are ‘operational’ Much impressed by Einstein’s work on relativity and its seemingly paradoxical conclu-sions about time, Bridgman argued that the only recourse
is a fairly stringent form of instrumentalism, whereby the concepts of science are reduced or replaced by the oper-ations necessary to achieve or measure them
Many professional philosophers have found Bridg-man’s thinking simplistic, arguing that science simply has
to be ‘open-ended’, reaching beyond its empirical base, making claims which transcend anything reducible to operations Bridgman himself conceded that sometimes the connection in science between concepts and oper-ations is ‘indirect’ In the opinion of critics, however, being ‘indirectly operational’ is somewhat on a par with

British philosophy today.Most (although not all) of the
philosophy practised in Britain today is firmly within the
tradition of analytic philosophy, a tradition shared with
North America, South Africa, and Australia (and certain
European countries, especially Germany and Austria) It
would be hard to argue that there was any longer a
char-acteristically British way of doing philosophy Certainly,
there are no movements peculiar to the country that are as
readily identifiable as that of British empiricism in the
seventeenth and eighteenth centuries, or the ‘ordinary
language’ philosophy of 1950s Oxford In addition, the
influence of North American philosophers has been very
substantial, and the initial stimulus for some research
pro-grammes has come from them (One indication of this
influence is the number of British university chairs taken
up by—or at least offered to—American philosophers in
recent years.) However, any country has its own
distinc-tive intellectual history, even if philosophical problems
and methods are international The following therefore
attempts to identify in a necessarily very selective way
some trends in the development of philosophy in Britain
since 1970, and some of the key personalities in that
devel-opment, rather than describe in detail any particular set of
problems
The legacy of Logical Positivism Following A J Ayer’s
vig-orous application of the principles of verificationism to
statements that appear to refer to a reality that is beyond
immediate appearances—statements about the past, for
example, Michael Dummett articulated a more
circum-spect anti-realism concerning such statements This
pro-ject has been extended by Crispin Wright, who has
developed a detailed account of what is at issue in disputes
concerning the reality of certain kinds of object A position
intended to be intermediate between *realism and
anti-realism, ‘quasi-realism’, has been articulated by Simon
Blackburn (now back in Britain after an extended stay in
the USA)
Philosophy of language and mind Greatly influenced by the
American philosophers Saul Kripke and Donald
David-son, work in the philosophy of language in the 1970s
(espe-cially in Oxford) placed the issues of truth and reference
centre stage, representing them as key to a number of
debates The two prominent questions were: Can the meaning of sentences be given by an account of what would make them true? and How do singular terms suc-ceed in referring to particular objects? Since then, and partly as a result of the work of Gareth Evans (d 1980), there has been a shift of focus towards mental representa-tion, the corresponding questions being: What deter-mines the content of a thought? and How does a thought succeed in being about a particular object? This second question is sometimes referred to as the problem of
*intentionality There has also been work on specific forms of mental representation—for example, spatial rep-resentation Interest in the relationship between language and mind led to the foundation in 1985 of a new
British-based journal, Mind and Language.
Philosophy of mind, on both sides of the Atlantic, was dominated in the 1970s and 1980s by two aspects of David-son’s work: the analysis of intentional *action and the defence of *physicalism (although action had already been the subject of studies by Stuart Hampshire and Elizabeth Anscombe) The worry was expressed, however, that Davidson’s own brand of physicalism (anomalous monism) was unstable—specifically, that it collapsed into
*epiphenomenalism In the 1990s, enthusiasm for phys-icalism waned somewhat with the emergence of doubts as
to whether a non-trivial form of physicalism could be articulated These doubts were quite independent of any renewed enthusiasm for dualistic accounts of the mind Among other developments could be mentioned the interest in computational models of the mind and the mechanisms underlying ascription of mental states to others
Metaphysics Britain in the 1950s and 1960s was not
particu-larly congenial to metaphysics, although the appearance
in 1959 of P F Strawson’s enormously influential Individ-uals: An Essay in Descriptive Metaphysics was an honourable
exception The last twenty years, however, has seen a remarkable resurgence of interest There has been increasing confidence in the power of language to capture substantial truths about the structure of the world, as opposed to the logical form of sentences, and a greater willingness to take certain kinds of statement at face value,
as positing the existence of things that are independent of our conceptual schemes (Perhaps one can identify the Australian influence here, through the work of such philosophers as David Armstrong and J J C Smart, but a major stimulus has been, once again, American, particu-larly in the form of David Lewis (d 2001).) Two debates
might be mentioned as illustrative (a) Realism concerning abstract entities Work in the philosophy of mathematics
has involved a reconstruction of Frege’s work on the existence of numbers as objects, and the articulation and defence of a mathematical ‘Platonist’ (i.e realist) position, and its extension to abstract entities generally What is distinctive about British work in the area is the attention given to the epistemological problems raised by Platonism, especially the question of whether it can be
