One important issue about the performing arts

con-cerns the matter of the authenticity of performances,

usu-ally construed as something more than mere correctness,

and covering matters such as conformity to the intentions

of artists, to antecedent performing traditions, or to the

historical contexts of creation of works A second

import-ant issue concerns the role of interpretation in

perform-ance, and what the relationship is between such

performative interpretation and the more straightforward

sort of interpretation—critical interpretation—involved

Peripatetics.This is the name given, first, to philosophers

who worked in the school founded by Aristotle (the

Lyceum or Peripatos), and, secondly, to later philosophers

who commented on and interpreted his writings Notable

members of the first group are Theophrastus (371–287)

and Strato (c.335–270), as well as Eudemus and Aristoxenus;

of the second, Aristocles of Messene, Aspasius (second

centuryad), and above all Alexander of Aphrodisias (early

third century ad) Peripatetics were characteristically

scientists or scholars, rather than philosophers That

stance reflects Aristotle’s division of inquiry into

autonomous specialisms for which he claims to have

com-pleted, in main outline, the philosophical foundations But

it ignores the tentative and dialectical character of the

philosophical originator of the Peripatos j.d.g.e

There is no satisfactory study of the Peripatetics in English; but

for Theophrastus, see W W Fortenbaugh et al., Theophrastus of

Eresus, 2 vols (Leiden, 1992).

Perry, Ralph Barton (1876–1957), a leading figure in the

movement of American *New Realism and the editor of

its manifesto (1912) Perry occupied the most extreme

position among his fellow realists—he was purest of the

pure He agreed with James’s neutral monism and

nega-tive answer to the question ‘Does consciousness exist?’,

and tried to explain perception without duplicating

objects, some of whose configurations were ‘physical’ and

others were what we ordinarily take to be ‘psychical’ In

General Theory of Value (1926), written after the steam had

gone out of New Realism, he gave a naturalistic account of

values, defining value as ‘any object of any interest’ By

virtue of his long tenure at Harvard, along with his

col-league C I Lewis, he did much to professionalize

philo-sophical teaching and research His biography of William

James won the Pulitzer Prize in 1936 l.w.b

persecution of philosophers Even the most unworldly

of intellectual disciplines has never been able to divorce itself entirely from the worldly conflict which determines the course of human history Philosophy was born into a society dominated by revolution and counter-revolution, and the earliest of its great exponents, Socrates, was exe-cuted because his teachings, it was said, corrupted the young Modern philosophy originated in an era no less revolutionary, and some of its leading exponents were exposed to similar dangers

Unused to having their own ideas taken seriously, philosophers today may be surprised to learn that the Par-liament of the time regarded the doctrines of Thomas Hobbes (1588–1679) as a probable cause of the Great Fire

of 1666 Safely dead, Hobbes is the greatest of British philosophers; alive and kicking, he was dangerous to know, and those in charge of the universities were not dis-tracted by the notion of academic freedom from persecut-ing anyone who sympathized with his ‘lewd, scandalous and immoral doctrine’ In 1668 Daniel Scargill was deprived of a fellowship at Corpus Christi College and expelled from Cambridge for being ‘an Hobbist and an Atheist’ Scargill was promised in 1669 that he could return if he delivered a public recantation: two drafts of this were rejected; in the third, the unfortunate Scargill confessed to having been an agent of the Devil, but he was never restored to his fellowship and was obliged to live in extreme poverty

The hostility of more orthodox thinkers was aroused above all by the intellectual ruthlessness with which Hobbes insisted that all divine authority must reflect earthly power Nothing is more binding than the word of God: this Hobbes would be the first to allow But, he argued, the word of God, like all words, may be inter-preted in rival ways What counts as an authoritative interpretation must therefore depend on the power of those capable of enforcing it

Benedict de Spinoza (1634–77) shared with Hobbes the honour of being regarded by all respectable persons with the horror of ‘atheism’ which is matched by the horror of

‘communism’ in the twentieth century Educated in the rabbinical tradition, Spinoza broke with Judaism: he was formally anathematized in 1656, and it is reliably reported that an attempt was made on his life Like Socrates, he took no payment from his pupils: ‘mischief ’, said one of his biographers, ‘could be had from him for nothing’ Like Hobbes, he repudiated the conventional conception of God and subjected the authority of Scripture to critical

scrutiny His Tractatus Theologico-Politicus (1670) was

pro-hibited by the authorities and placed on the Index of the Catholic Church

Bertrand Russell (1872–1970) challenged conventional wisdom throughout his long life His opposition to the First World War led to imprisonment and his being deprived of his lectureship at Trinity College, Cambridge

A decisive influence on the campaign against nuclear weapons in the 1960s, and an advocate of civil disobedi-ence, he was also—with Jean-Paul Sartre (1905–80)—a

Marriage and Morals (1929) was cited as evidence of his

depravity when he was deprived of the professorship he

had been offered at the City College of New York in 1940

La Guardia, the Mayor of New York, described Russell as

‘an ape of genius, the devil’s minister of men’ An

applica-tion was made to the State Supreme Court to compel the

Board of Education to rescind the appointment Russell,

the Court was told, should be regarded ‘not a philosopher

in the accepted meaning of the word’ but as someone who

‘by cunning contrivances, tricks and devices and by mere

quibbling puts forth fallacious arguments and

argu-ments that are not supported by sound reasoning’, an

advocate of everything ‘lecherous, libidinous, lustful,

ven-erous, erotomaniac, aphrodisiac, irreverent,

narrow-minded, untruthful, and bereft of moral fibre’ Russell, it

was added, also ‘winks at homosexuality’

It would honour the profession if it could be said only

that philosophers have been persecuted; but the truth is

that, if philosophers have been among the hunted, they

have also been among the hunters Hobbes’s

contempor-ary Ralph Cudworth was a philosopher too, but he was

also Master of Corpus Christi: when Scargill was expelled,

Cudworth’s name was on the expulsion order Spinoza’s

contemporary Leibniz, a great philosopher in his own

right, must surely have recognized Spinoza’s greatness;

but he pretended otherwise Russell’s contemporary

persistence through time.That something continues to

exist from one moment to the next has been seen by some

philosophers as requiring explanation Each point in *time,

they say, is ‘logically independent’: from the fact that

any-thing exists at a particular time, it does not follow that it

must exist at some later time Hence, if an object persists

through time, this must have some cause Descartes and

Spinoza both hold, though in significantly different ways,

that God is the cause, the former presenting this as a proof

of God’s existence Leibniz relies on the same

consider-ations to argue that all true propositions are analytic: if you

are the same individual you used to be, he says, this can only

be because your existence then and now are both essential

to your nature Hume, by contrast, argues that the very

notion of an object persisting through time is a ‘fiction’

derived from our propensity to run into one a sequence of

experiences that are essentially distinct c.w

person-affecting principles Some moral principles evalu-ate choices in what Parfit calls ‘person-affecting terms’, which appeal to a choice’s effects upon the interests of particular individuals One choice is morally worse than

another in these terms only if it is worse for at least some

specific individual, who would have fared better given the other choice According to Parfit, person-affecting prin-ciples at best are only part of a plausible moral theory since they fail to explain why certain choices which affect the membership, as well as interests, of *future generations are wrong For example, if a choice between risky and safe energy policies determines both whether a catastrophe occurs and which distinct set of individuals (all with lives worth living) exists, in the distant future, then the former cannot be criticized in person-affecting terms, since there

is no affected individual who would have fared better had

personal identity The way philosophers refer to facts about *persons which are expressed in identity judge-ments such as ‘The person over there now is identical to the person who was there yesterday’, the truth of which is

a consequence of the fact that persons remain in existence over time The problem is to say in an informative way what the necessary and sufficient conditions are for this kind of fact These conditions are called criteria of identity for persons A second related problem, raised by Parfit, is what importance facts about such identities should have

in our evaluative thought

No consensus on the first problem has emerged What has proved difficult is finding a balance between the intu-itions that are generated by imaginary cases, for example, brain transplants, which indicate that psychological conti-nuities are crucial, and, by contrast, our actual practices of tracing people plus a sense of our identity as concrete sub-stances, which seem to link us to something substantial Theories can be classified in various ways; one division

is between those which state the criteria in psychological terms and those which do not; another, regarded as important by Parfit, is between theories which view per-sonal identity as reducible to other continuities and those which do not; a third division is between theories which tie the person to a continuing substance, say the body, brain, or soul, and those which do not

Locke’s influential theory is of the latter sort He pro-posed that persons are essentially capable of self-consciousness Their identity should be analysed in terms

of *consciousness, which is standardly interpreted as the proposal that a person is identical with whoever’s exploits they remember as their own—the memory criterion His negative thesis is that this consciousness is not necessarily tied to a body or soul

The neo-Lockean research strategy defends a modified Lockean view To avoid possible circularities in the use

of the concept of memory they have constructed

personal identity 691

psychological concepts, which are explicitly defined

with-out using the concept of personal identity The

psycho-logical continuities required are weakened The structure of

the theory is more complex to deal with problems of fission

The major alternative approach to this tradition

requires the persistence of some substantial item for the

person to survive A Cartesian view is that we have

non-material souls and survive so long as the particular soul

does More popular, though, are accounts according to

which the continuant required must be physical One

sug-gestion, defended by Williams, is that the person is tied to

the body This fits our treatment of actual cases, but

gen-erates a counter-intuitive verdict when we consider

imagin-ary ones A related theory, developed by Wiggins, is that it

is a mistake to allow, as Lockeans do, any distinction

between the person and the animal Personal identity is,

on this view, a case of animal identity

An alternative physicalist account claims that a person

is tied to that (physical) item which sustains the person’s

basic psychological capacities, supposedly the brain This

fits certain intuitions better than bodily theories, but has

difficulty explaining exactly why psychological

continu-ities grounded in more radically non-standard ways are

not also enough for the person to survive

The difficulty of constructing a defensible theory has

led to a reconsideration of the methods philosophers have

employed, which has been encouraged as well by Parfit’s

discussion of whether personal identity matters He

argues, in various ways, that it does not, one being

that brain-splitting plus transplants would give what

mat-ters to us but, because it generates two candidates, does

not preserve the original person So, he concludes,

identity does not matter Many are unhappy with Parfit’s

conclusion, and also wish to reconsider the method

employed to reach it

These methodological inquiries have led to no

agree-ment, and all of the described theories are under active

personalism.As a label applied primarily to the

philoso-phy of the French thinker Emmanuel Mounier (1905–50),

a Christian version of existentialism stressing communion

on the basis of shared values, with the person, as distinct

from the political individual, as the locus of a ‘unique

voca-tion’ directed towards fellowship Other philosophers

who have made personhood a fundamental concept

include the German philosopher Rudolf Hermann Lotze

(1817–81), the American idealists Josiah Royce

(1855–1916) and Edgar Sheffield Brightman (1884–1953),

and the Scottish humanist, John Macmurray (1891–1976) Common to these thinkers is the view that the finite indi-vidual is somehow grounded in and seeks its fulfilment in

an infinite spirit, or God, understood as personal, though Macmurray opposed idealism and considered ‘God’ mainly a negative concept given positive content only in actual relations among persons Personalism in these wider senses has affinities with the process theism of Alfred North Whitehead (1861–1947) and Charles Hartshorne (1897–2000) An early exponent was the Nor-wegian philosopher Niels Treschow (1751–1833) a.h

persons. On a purely functional view, possession of a range of specific psychological capacities is both necessary and sufficient for being a person The characteristics in question are determinable *a priori by reference to our concept of a person Locke’s definition of a person as ‘a thinking intelligent Being, that has reason and reflection, and can consider it self as it self, the same thinking thing in different times and places’ is an example of a functional definition Given this approach, there is no reason in prin-ciple why an artefact or immaterial soul should not count

as a person, as long as the functional conditions are met

On the other hand, a brain-damaged human being who lacks the relevant capacities will fail to count as a person Descartes claimed that a person is a compound of body and soul It has been objected that talk of immaterial souls

is illegitimate because of difficulties in specifying singular-ity and identsingular-ity conditions for them Instead, P F Straw-son proposes that the concept of a perStraw-son is ‘primitive’, that is to say, it is of a type of entity such that both predi-cates ascribing states of consciousness and those ascribing corporeal characteristics are equally applicable to a single individual of that single type

The most familiar examples of persons in the Strawson-ian sense are human beings Some have claimed that only human beings can be persons, or, more modestly, that persons must at least be animals of some sort According

to what David Wiggins calls the animal attribute view of persons, a person is any animal that is such by its kind as to have the biological capacity to enjoy fully an open-ended list of psychological attributes The list of attributes is to be filled in by reference to the class of actual persons The animal attribute theory is, in some respects, more restrictive than a purely functional approach It rules out non-animal persons, and does not even allow that posses-sion of the enumerated psychological attributes is suffi-cient for an individual animal to count as a person; the

animal must also be a typical member of its kind On the

other hand, the animal attribute theory is more permis-sive than the purely functional approach to the extent that

it does not exclude from the class of persons a brain-damaged human being who has lost the psychological capacities included in the functional definition

692 personal identity

Trang 4

The most serious challenge facing the animal attribute

view results from reflection about what the identity of a

person consists in If, as Locke argued, the persistence of

the animal with which a person shares her matter is

nei-ther necessary nor sufficient for the persistence of the

per-son, the person and the animal cannot be identical For

writers influenced by Locke, *personal identity is to be

understood as consisting in the obtaining of various forms

of psychological continuity or connectedness This

approach may be motivated both by ethical

consider-ations and by reflection on puzzle cases From the fact that

the continuities in question are not all or nothing, some

have drawn the conclusion that persons have an

onto-logical status akin to that of clubs or nations Another view

would be that a person is what underlies her psychological

capacities, namely, her brain

In defence of his position, the ‘animalist’ may argue that

thought experiment and conceptual analysis are not the

best way of theorizing about persons and personal

iden-tity The most reliable point of reference for an

under-standing of the nature of persons is what is known about

the nature of *human beings, even if such an approach

lays itself open to accusations of parochialism If some of

our intuitions about puzzle cases conflict with our best

overall theory of persons then we may be entitled to reject

*animalism

pessimism and optimism The metaphysical theories that

this world is, respectively, the worst and the best of all that

are possible Taken in this literal, cosmic

sense—worst-ism and best-sense—worst-ism—the theories are of relatively recent

date, at least in Western thought, optimism going back to

the eighteenth, pessimism to the nineteenth century The

history of the terms themselves reflect the recent growth

of the theories ‘Optimisme’ came into currency in France

towards the middle of the eighteenth century, with the

English word ‘optimism’ following somewhat later in the

century From the outset, the term was used to describe

Leibniz’s position, particularly as developed in his

Théodicée (1710) The first recorded use of the antithetical

term ‘pessimism’ is in a 1794 letter of Coleridge By the

1880s it had also generally established itself as the name of

a metaphysical system—that in Schopenhauer’s Die Welt

als Wille und Vorstellung (1819).

Hence there are good historical and etymological grounds for regarding—as I shall here—the metaphysical theories as embodying the primary meanings of the two terms, even though current usage is much vaguer, largely indicating a negative or positive attitude towards things The two terms are also used more precisely and narrowly

to refer to the value of human existence In this anthropo-logical sense, the Platonic and Artistotelian ideas of human perfectibility are taken to be optimistic; whereas statements of pessimism are to be found in the books of

Ecclesiastes and Job as well as in Oedipus at Colonus, where

Sophocles writes that ‘Not to be born is the most to be desired; but having seen the light, the next best is to die as soon as possible’

Leibniz’s metaphysical optimism is based on his ration-alistic theology From the ontological argument, he knows that God, the most perfect being, exists; and such a being must have created the best of all possible worlds; hence this must be that world Imperfections are explained as necessary for this richest compossible whole—just as shadows are required by a picture to give form to the light and colour

For Schopenhauer, on the other hand, this world is so bad that if it were to become even slightly worse it would collapse into chaos Any goods and pleasures are required for this compossibly worst whole Schopenhauer’s pos-ition is based on his metaphysics, although this is often overlooked by those more familiar with his popular essays than his main philosophical work Whereas Leibniz’s metaphysics is rationalistic, Schopenhauer’s is empirical, based on an inner, immediate experience of our living bodies as will or desire Hence the real, underlying nature

of the world is not a most perfect being; rather it is will, feeding and preying upon itself Desire is positive, satisfac-tion is the negasatisfac-tion or suspension of desire Hence the world is wrong, both morally and in the preponderance of pain over pleasure Nor is there any hope that it can be rec-tified, since the fault lies in the substance rather than any accident or form of the world Schopenhauer develops this thesis by drawing on Kant: the apparent orderliness, goodness, satisfaction in the world derive not from what the world is in itself, but from the structuring required to make it into a perceivable, livable world at all Schopen-hauer also draws inspiration from Buddhism and Hin-duism, which he regards as essentially pessimistic religions—as opposed to Judaism and Islam, which he takes to be optimistic Yet at times he seems to recognize that, like Christianity, most major religions contain both optimistic and pessimistic elements: they are more or less pessimistic about this world and more or less optimistic about the next or real world

While pessimism and optimism have never been cen-tral issues in philosophy, pessimism did have some vogue

in Germany towards the end of the nineteenth century,

chiefly from Eduard von Hartmann’s elaborate Philosophy

of the Unconscious (Eng tr 1884), which develops

Schopen-hauer’s pessimism, while trying to combine it with Hegelian elements Anglo-American philosophers have

Trang 5

shown little interest in the debate, apart from Sully’s work

(see below) and occasional witty criticism—as, for

example, in William James’s ‘German Pessimism’ (1875)

What is probably most memorable about Leibnizian

optimism is its satirical rebuttal in Voltaire’s Candide

(1759) While Schopenhauer’s pessimism has produced no

similar satire—which is itself, perhaps, notable—it has

inspired the influential reactions of Nietzsche, beginning

with his Birth of Tragedy (1872), which largely accepts

Schopenhauer’s pessimism, although sublimating it

through the ideal of tragic life Yet in his later writings,

Nietzsche is hostile; for while he agrees in general with

Schopenhauer’s description of the will, he forcefully

opposes his negative, ascetic attitude towards it with a

joyous affirmation

Nietzsche’s provocative views on truth can also be seen

as a reaction to Schopenhauer For while Schopenhauer

was a pessimist about the world, he was an optimist about

knowledge and truth; for it is through knowledge, he

holds, that any good is achieved—either in transitory,

will-less aesthetic contemplation, or in the insight leading

to ascetic renunciation and nirvana, the highest and

most lasting good Nietzsche, in short, reverses this: he

is a metaphysical optimist, but an epistemological

pessimist, warning of the dangers for life of knowledge or

phenomena and noumena These terms mean literally

‘things that appear’ and ‘things that are thought’ Platonic Ideas and Forms are noumena, and phenomena are things displaying themselves to the senses In Plato’s metaphor

of the divided line (Republic, bk 6), whatever lies above the

dividing-line is noumenal, that which is below it is

phenomenal In Republic 517b the distinction is between

that which is revealed to sight and that which is intelligi-ble; at 524c the contrast is between terms cognate with noumena and phenomena This dichotomy is the most characteristic feature of Plato’s dualism; that noumena and the noumenal world are objects of the highest know-ledge, truths, and values is Plato’s principal legacy to philosophy

Kant deals with this duality in his Inaugural Dissertation

(1770), On the Form and Principles of the Sensible and the Intel-ligible World The intelIntel-ligible world of noumena is known

by pure reason, which gives us knowledge of things as they are Things in the sensible world (phenomena) are known through our senses and known only as they appear To know noumena we must abstract from and exclude sensi-ble concepts such as space and time

Kant called the determination of noumena and phe-nomena the ‘noblest enterprise of antiquity’, but in the

Critique of Pure Reason he denied that noumena as objects

of pure reason are objects of knowledge, since reason gives knowledge only of objects of sensible intuition (phenomena) Noumena ‘in the negative sense’ are objects of which we have no sensible intuition and hence

no knowledge at all; these are things-in-themselves Noumena ‘in the positive sense’ (e.g the soul and God) are conceived of as objects of intellectual intuition, a mode of knowledge which man does not possess In neither sense, therefore, can noumena be known For both Plato and Kant, nevertheless, conceptions of noumena and the intelligible world are foundational for

phenomenalism.The doctrine that physical objects are

reducible to sensory experiences, or that physical object

statements can be analysed in terms of phenomenal

state-ments describing sensory experience The main

twenti-eth-century defenders of the view, A J Ayer and C I

Lewis, tried, each in his own way, to show how the

con-tent of a physical-object statement involves appeal to

nothing more than sense-*contents or *sense-data, or

any-how sensory *experience Consider: (1) This snowball is

white (2) There is a white sense-content Does 1 have an

analysis in terms of 2? If so, 1 must entail 2, but it does not

Nor does it help to assume that one is looking at the

snow-ball and only at the snowsnow-ball, or to ignore the experience

of everyone else, etc This last is especially problematic if

we wish to construct selves from sense-contents Let us

waive that, however, and consider further the following:

(3) The light shining on this is red The conjunction of 1

and 3 together with assumptions of the sort indicated will

actually entail not-2, and hence cannot entail 2 And it is

then hard to conceive of any sense-contents whose

exist-ence would be entailed by a particular physical fact, even

one as simple and observational as that reported by 1, even

when combined with assumptions like those above

(exclusive of 3) (See R M Chisholm, ‘The Problem of

Empiricism’.)

Moreover, phenomenalists must invoke not only

actual but also merely possible phenomena, possible

experiences For a particular grain of sand may never be

associated with any actual phenomena, since no one may

ever perceive it There is of course no hope of isolating the

single fact of there being a snowball before me by means of the

one *conditional that if I were to open my eyes I would

have a visual experience of whiteness and roundness

There are ever so many different conditions that in the

absence of snow still give rise to the truth of that

condi-tional But perhaps the idea is rather this: if we consider

the possible courses of action open to me at the moment

and the experiential outcomes conditional upon those

courses of action, some such infinite set of conditionals

would capture the single fact of there being a snowball

before me If so, we could perhaps say that there being a

snowball before me was necessarily equivalent to the joint

truth of that set of conditionals

However, the introduction of such possible

phenom-ena imports a complication, for the possibilities in

ques-tion must be in some sense ‘real’ and not just logical But

real possibility is grounded in actual conditions And what

could function as the ‘base’ or ‘ground’ for the

phenom-enalist’s actual conditions relative to which his possible

phenomena are to be defined? What can ground such

con-ditionals as: I would experience a sense-content of

some-thing white if I acted in a certain way? Presumably it

would be just me and my properties (whether or not I

myself am also to be reduced, as in *neutral monism, or to

be left standing as in Berkeley’s subjective *idealism) If so,

then the fact that there is a white piece of paper before me

has a status relative to me similar to the status of the

elas-ticity of a rubber band relative to the rubber band

A major problem for such phenomenalism stems from perceptual relativity: white paper looks white under white light, red under red, etc Any possible course of experience resulting from a possible course of action will apparently underdetermine our surroundings: it will determine,

for example, that there is either white paper under red light

or red paper under white light, or the like For this reason

among others, phenomenalism now has few defenders

phenomenology.One of the most important philosoph-ical movements of the twentieth century It was founded

by Edmund Husserl at the beginning of this century and has had many followers, for example, Moritz Geiger, Alexander Pfaender, Max Scheler, Oscar Becker, up to the present Quite naturally, it has undergone many changes, refinements, shifts of emphasis, etc Originally, it was pri-marily a theory of *knowledge Later on, in the years after

1913, phenomenology developed into a form of *idealism Phenomenology distinguishes sharply between per-ceptual properties on the one hand, and abstract proper-ties on the other Consider two white billiard balls, called

A and B The white colour of A, which one can see with one’s eyes, is said to be located in space where A is The white colour of B, similarly, is taken to be located where B

is Furthermore, it is maintained that the colour of A is not identical with the colour of B, since they are located at two

different places The same shade of colour, according to this analysis, divides into as many ‘colour instances’ of that shade as there are individual things with this colour shade However, all of these instances are instances of the same colour shade There exists, therefore, according to phenomenology, also the abstract colour shade of which the instances are instances Let us call this abstract colour the ‘universal whiteness’ Phenomenology asserts that there is not only a direct perception of instances of white-ness, but also a sort of direct perception of the universal whiteness This perception is called ‘eidetic intuition’ By means of eidetic intuition we have knowledge of the essential features of the world Phenomenologists call such universals *essences

An essence can be presented to the mind in its totality in one mental act of intuition Perceptual objects, however, can never be so presented According to phenomenolo-gists, we can only perceive aspects of them This is one of the fundamental differences between essences and certain individual things What does it mean to perceive merely aspects of, say, one of our billiard-balls? There seem to be

phenomenology 695

Trang 7

two notions of an aspect at work Firstly, we must

distin-guish between the colour instance of billiard-ball A, which

is a part of A, and the differently coloured sensations

which we experience when we look at A Assume, for

example, that A is illuminated from one side, so that half of

it lies in the shadow Even though that billiard-ball is

formly coloured, our colour sensation of it is not

uni-formly white: one part of it is much darker than the other

And if we were to put on coloured glasses, our colour

sen-sation would not be white at all Now, what

phenomen-ologists sometimes seem to have in mind when they speak

of perception through aspects is that the property

instances of a perceptual object, its colour, its shape,

appear to us only through the perspective variations of

our colour sensation and the variations of our shape

sensations

Secondly, and much more obviously, spatial perceptual

objects can only be perceived from a point of view For

example, when we look at billiard-ball A, only one side is

turned towards us and we cannot see its back In this

sense, therefore, we can only perceive, from a given point

of view, a spatial ‘aspect’ of it It is clear that this notion of

an aspect is quite different from the one mentioned in the

last paragraph

According to phenomenology, therefore, our

know-ledge of things divides into direct and indirect knowknow-ledge,

that is, into direct knowledge and knowledge through

aspects Essences (universal properties) are known

directly, but perceptual objects are only known through

their aspects However, in addition to perceptual things,

there are also mental things and selves How are they

known? *Consciousness, according to phenomenology, is

known, like essences, directly The mental act of seeing a

billiard-ball, a desire to be once again in Venice, a

remem-brance of strolling down the beach in Manly, all of these

so-called mental acts are presented to us without aspects

There is thus a fundamental difference between the

objects of the outside perceptual world and the objects of

the world of consciousness: the former are never given to

us wholly and completely in single mental acts of

percep-tion, the latter are fully given to us when we attend to

them But the self, the mental individual from which all

mental acts issue, is only presented to us indirectly, like a

perceptual object The realm of individual things thus

divides into an ‘immanent’ part, consciousness, and two

‘transcendent’ parts, perceptual objects and the self This

makes consciousness special, because what we truly and

directly know is only consciousness But some

phenom-enologists go even further and claim that consciousness

has a kind of being quite different from all other things

This claim plays an essential role in *existentialism

So far we have appraised phenomenology as a theory of

knowledge But it is often viewed not as a new

philosoph-ical view about old epistemologphilosoph-ical problems, but as a

new method of doing philosophy, and one speaks then of

the phenomenological method Sometimes, one even

talks of the science of phenomenology, which is claimed

to have its own method and subject-matter

So-called eidetic reflection, reflection on essences and their connections, is of course the heart of phenomen-ology This reflection requires eidetic reduction By means of eidetic reduction, we shift our attention from a particular instance of a property to the abstract property (essence) itself After the shift has taken place, one will

‘see’ the essence directly and in its totality Furthermore, after eidetic reduction, one also intuits connections among essences One may intuit, for example, that the essences of ego and of spatial being reveal that the former can perceive the latter only in spatial perspective Phe-nomenology, from this point of view, inquires into the structures formed by essences

The knowledge gained by a study of the relationships among essences, according to most phenomenologists, is non-empirical For example, the insight just mentioned that an ego can perceive a spatial being only in perspective

is gleaned from a connection between the essence of an ego and the essence of something spatial; it is not inferred

by induction from individual cases Such an inference, for example, would be involved if one concluded from repeated observations of particular whales that all whales are mammals But phenomenological truths are thought

to be not only non-empirical in this sense, but also neces-sary The inductive law about whales may be proven false, for example, by the discovery of a whale that is not a mam-mal but a fish No such possibility exists, however, for the phenomenological truth about the connection between the essence of being an ego and the essence of observing spatial things Since phenomenological truths are thought

to be both non-empirical and necessary, they are said to be true a priori

But this is not all there is to the phenomenological method There is also phenomenological reduction It seems that there are two sides to phenomenological reduc-tion Firstly, there is a general prescription to look at things without prejudice, to go to the things themselves, to leave theoretical speculation behind, etc Secondly, however, there is also a more specific side to phenomenological reduction It consists, as a first step, in the *‘bracketing of the objective world’ Phenomenologists rely at this point

on a thesis which was defended by the Polish philosopher Twardowski, who, like Husserl, was a student of Brentano’s Twardowski distinguished between an indi-vidual act of presentation, the content of this act, and the object of the act Assume that one is presented with the

bil-liard-ball A Then there occurs a particular mental act of

presentation This act has a unique content which is a prop-erty of the mental act, and it has, as its object, the

billiard-ball A Twardowski’s thesis is that every act has an object,

even those acts which intend things which do not exist If one hallucinates a big polka-dotted bat, one’s act of seeing has an object, even though this object does not exist In gen-eral, Twardowski insisted (for example, against Bolzano) that we must distinguish between the question whether a mental act has an object and the question whether its object exists Some mental acts have objects which do not exist Phenomenological reduction is then a method of revealing

696 phenomenology

Trang 8

the essences of the objects of our mental acts, irrespective

of whether these objects exist in reality, even irrespective of

whether there really is a non-mental reality

Phenomenological reduction enjoins us to study the

objects of our mental acts precisely as they are, and

irre-spective of their existence But for some

phenomenolo-gists this is only the first step They adhere to the much

more radical prescription that we must eventually turn

away from the ‘outside world’ and concentrate

exclu-sively on consciousness In one of Husserl’s later versions

of the nature of phenomenology, this exclusive

concen-tration on consciousness sets phenomenology apart from

the natural sciences Phenomenology thus has its own

method, reflection on the essences of mental acts, and it

has its own subject-matter, consciousness

Phenomen-ology, according to this conception, is the study of the

essence of consciousness The idealistic tenor of this

even though they were ‘necessarily prevented by external circumstances’; thus a log, he held, would still be capable

of burning, even though it was in mid-Atlantic Philo also invented *material implication: one proposition implies another, he held, when and only when either the first proposition is false or the second proposition is true; in particular, he held that the *conditional ‘If it is day, it is night’ is true, and that the argument ‘It is day; so it is night’

is valid, throughout the night but never in daytime

philosophe.A French word now domesticated into Eng-lish, denoting any member of a very diverse though loosely associated group of scientists, writers, statesmen, and prac-tical ‘men of affairs’ whose works and activities constituted the eighteenth-century *Enlightenment movement in Europe and America (e.g Voltaire, Hume, Franklin, Buf-fon, and Diderot) The philosophes were bound together as

a group by their vigorous support of the developing natural sciences, by their insistent (and frequently courageous) challenges to the pervasive influence of outdated trad-itions, superstition, and prejudice, and by their common desire to facilitate the growth and spread of more liberal and humane political institutions All of these concerns, in the philosophes’ view, were only different sides of a single intellectual mission: to advance the cause of human reason,

to perfect its methods, and extend their application across

an ever widening range of pursuits p.f.j

philosophical inquiry: premisses and first principles.

There is an aspect of philosophy that is pervasive enough

to be sometimes used to define it: the criticism of

assump-tions Considering various ways of arriving at or

approxi-mating to knowledge, Plato places at the top ‘dialectic’ It

seems to be what *philosophy essentially consists of, and

its nature is explained by contrasting it with mathematics,

in which unargued and unexamined assumptions are

taken for granted Rational thinking without assumptions

is, however, an inconsistent notion *Reasoning is

move-ment from an accepted or assumed belief to some other

belief Even if the premiss is merely assumed and not

accepted, supposed, as the saying is, for the sake of

argu-ment, some rules of inference (and very often some

sup-pressed premisses as well) are required to provide the

conclusion drawn

A certain amount of philosophy has been presented in

an explicitly deductive form, with axiomatic premisses set out at the start as in the fascinating model of Euclid’s

geometry Spinoza gave his great work Ethics the subtitle Demonstrated in a Geometrical Manner His axioms turn out

to be quite numerous; there are seven for the first book, five for the second, and comparable handfuls for the other three, supported in each case by definitions Spinoza did not think that any philosophy set out in this way, even if all the inferences in it were valid, was on that account cor-rect He produced a version of Descartes’s system in this rigorous form but thought it in many respects mistaken The axioms had to be true, and that meant, since they could not be inferred, that they had to be self-evident

It is a general characteristic of rationalist philosophers to argue in this way, for example of Descartes and Leibniz and, in our century, of McTaggart Descartes presents ‘I think, therefore I exist’ as a kind of ultimate premiss, but does argue for it, assuming that ‘I think’ entails ‘I exist’ and asserting that the denial of ‘I think’ is self-refuting He then goes on to conclude that, since his premiss has the self-certifying property of being ‘clear and distinct’, any other belief with that certifying property is also known for cer-tain to be true, a principle used to authorize a number of substantial propositions McTaggart claims to deduce his entire philosophy from the axioms that something exists and an obscure ‘principle of determining correspondence’ Rationalist philosophers commonly proceed, at least in the first stages of their work, by way of indirect proof or

reductio ad absurdum, in which a proposition is established

by inferring a contradiction from its negation If that is to work it must be assumed that the inference involved is val-idated by a true logical law and that a contradiction is neces-sarily false The thesis about contradictions is not and the relevant logical laws need not be things anyone would be likely to question

But full-blooded deductive metaphysicians of this kind are rare; a rationalist need not be a rationalist through and through On the other hand, the minimization of assump-tions is also to be found among empiricists, particularly if they are mathematically trained and inspired Russell pro-posed, and sketched, the achievement of a ‘minimum vocabulary’ for the description of the world by definitional

reduction, and that project was realized in Carnap’s Logical Structure of the World, in which the main elements of the

whole apparatus of description are defined in terms of items

of sense-experience and the relation of recollected similar-ity But most empiricists follow a less arduous path The absolute first principle of *rationalism would seem

to be: whatever it would be a contradiction to deny is neces-sarily true Empiricists would not deny that, but would maintain that while it determines the form of our repre-sentation of the world, it implies nothing about what the world is in fact like Yet they too have, and give prom-inence to, large basic principles

Locke, Hume, and Mill hold that all, or most, substantial items of knowledge (or justified belief ) derive their title to acceptance from sense-experience (or introspection) That

698 philosopher-king

Trang 10

seems broadly correct, but is it really self-evident? The

claims of alleged moral, aesthetic, and religious experience

have to be dealt with as do those of such substantial, but

apparently unempirical, generalities as that every quality

inheres in a substance, every event is part of the history of

an object, and every event has a cause

The classical Empiricists were, in fact, committed by

their conception of the nature of philosophy as an

empir-ical study of the cognitive aspects of human nature to the

view that the empiricist principle was itself empirical The

problem came to the surface in connection with the

prin-ciple of verifiability, the twentieth-century version of the

empiricist principle Critics asked what sort of truth it itself

was: empirical or, the only alternative its proponents

acknowledged, analytic, true in virtue of the meaning of

the words expressing it? Neither option was very

attrac-tive To admit it was empirical left it weak and refutable

To claim it was analytic seemed to conflict with the facts

of our use of the word ‘meaning’ Popper frankly admitted

that his roughly similar criterion of falsifiablity, as a means

of demarcating not sense from nonsense, but science from

metaphysics, was a proposal or convention,

recom-mended on the grounds of its intellectual advantages

That undogmatic, persuasive conclusion is supported

by the widespread recognition that the theory of

know-ledge is a normative discipline, an ‘ethics of belief ’, setting

out rules for the right acceptance of beliefs That would

make it nonsense on the strict letter of the verifiability

principle, but, one might say, so much the worse for the

verifiability principle Many present-day philosophers,

however, following Quine, have gone back to the position

of the classical empiricists by taking the theory of

know-ledge to be the cognitive part of empirical psychology

Many unexamined assumptions are more embedded in

philosophical writing than those mentioned so far One,

which had a long and significant career, is that the greater

cannot emerge from or be produced by the less It is

stated, as something too obvious to require discussion, by

Descartes, and drawn on by Locke to prove the existence

of God It was mobilized again in the nineteenth century

to dismiss Darwin’s doctrine of evolution, but Darwin’s

view emerged victorious from the collision Another is

that sturdy support of mind–body dualism which denies

the identity of a mental event with any corresponding

brain event on the ground that it is conceivable or logically

possible for either to occur without the other occurring

J J C Smart pointed out that there is such a thing as

con-tingent identity as of a lightning-flash and an electrical

dis-charge, or, one might add, of a billiard-ball that is seen and

one that is touched

A philosophical treatise may be presented in a

system-atic order which does not correspond at all to the way in

which the ideas it contains were arrived at Premisses and

first principles are, therefore, more part of the expository

rhetoric of philosophy than of its real substance But

orderly exposition nevertheless contributes valuably to

making philosophy accessible to the kind of rational

philosophical journals: see journals of philosophy philosophical logic Despite its name, philosophical logic

is neither a kind of logic nor simply to be identified with the philosophy of logic(s)—the latter being the philosoph-ical examination of systems of logic and their applications Though the subject of philosophical logic is hard to define precisely, it may loosely be described as the philosophical elucidation of those notions that are indispensable for the proper characterization of rational thought and its con-tents—notions like those of reference, predication, truth, negation, necessity, definition, and entailment These and related notions are needed in order to give adequate accounts of the structure of thoughts—particularly as expressed in language—and of the relationships in which thoughts stand both to one another and to objects and states of affairs in the world But it must be emphasized that philosophical logic is not concerned with thought inasmuch as the latter is a psychological process, but only

in so far as thoughts have contents which are assessable as true or false To conflate these concerns is to fall into the error of *psychologism, much decried by Frege

No single way of dividing up the subject-matter of philosophical logic would be agreed upon by all of its prac-titioners, but one convenient division would be this: the-ories of reference, thethe-ories of truth, the analysis of complex propositions, theories of modality (that is, of necessity, possibility, and related notions), and theories of argument

or rational inference These topics inevitably overlap, but

it is roughly true to say that later topics in the list presup-pose earlier ones to a greater degree than earlier ones pre-suppose later ones The order of topics in the list reflects a general progression from the study of parts of *itions, through the study of whole and compound propos-itions, to the study of relations between propositions (Here we use the term ‘proposition’ to denote a thought content assessable as true or false—something expressible

by a complete sentence.) Theories of *reference are concerned with the relation-ships between subpropositional or subsentential parts of thought or speech and their extra-mental or extra-linguistic objects—for instance, with the relationship between

*names and things named, and with the relationship between predicates and the items to which they apply According to some theories, a name refers to a particular thing by virtue of its being associated with some descrip-tion which applies uniquely to that thing Other theories hold that the link between name and thing named is causal

in nature (Theories of either sort are intimately bound up with questions concerning *identity and *individuation.)
