When

Iurged Professor

Moore

topublish these lectures

which

he gave

some

fortyyearsago he said to

me

'But surely they are out of

date.' Certainlythey are outofdate. Moore's

own

work

in

philo-sophy

over thesefortyyears is

by

itself

enough

to render

them

out

ofdate.

Anyone

hearing theselectures atthetimetheywere given

might

have guessedthatthey

would

soonbeout ofdate.

For

inthese

lecturesphilosophyis

done

withadirectness

and

honesty

and

inci-civeness

which

atoncegives

hope

that

we

may,working with

Moore,

soon cut a

way

out of the jungleintothelight. Itis the

same hope

we

felt

when

we

read

what

we

stillread Moore'sPrincipiaEthica

and

his Philosophical Studies.

That hope was

justified.

Amongst

theproblems

which

agitate philosophers there are

two

which, I think, strikethe non-philosopher as especiallyremote, as typically frivolous.

They

arethe

problem

of theexternalworld

and

the

problem

of generalideas.

When

the philosopher asks

'Do

we

really

know

what

things are

good and what

are bad?',

when

he asks

'What

is goodness?' the

plain

man

sympathizes.

When

the philosopher asks

'Do

we

really

know

of the existence of

mind

?

J

'How

do

we

know

the past?'

'What

do

we

mean when we

speakof consciousness or of

what no

longer

exists?'theplain

man may

still

manage

tosympathize.

But

when

the philosopher asks

'Do

we

really

know

that thereis bread here

and

now

in our

mouths

?'

'What do

we

mean when

we

speak of chairs

and

tables?' then the

whole

thing is aptto

seem

ridiculous to the plain

man.

And

when

the philosopher then asks

'What

is it to

mean

any-thing?'

'What

isittohavea general idea ofanything?'

'What

is itto

havea universal before themind,to noticeitspresenceinsomething beforeone?'

'What

is itforaquality tobepresentin this

and

alsoin that?1thentotheplain

man

itseemsthatthe philosopherisgetting

himself into a difficulty

by

asking for the reduction to something

more

simple of

what

couldn't

be

simpler.

Moore

manages

to present these central, limiting, typical

prob-lemsinsucha

way

that the reader inspiteof himself beginstofeel

them.

And

withoutthis feelingof the difficultytherecan

be no

full

understanding of

what

it is to

remove

it.

The

idea that there is

(4)

FOREWORD

much

can be

done

about it.

For

this reason alone Moore's

intro-duction to philosophical difficulties can help us tojudge

and

to

understandthe

most

modern

attemptsto resolvethem*

But

further theruthless

claritywith

which

Moore

shows

usthepathless jungle

before us helps us to realize

what must

be

done

to get through.

There

is

no

path.

We

must

cuta

way

from

treeto tree.

Itoftenhappens of coursethatone cannottell

where

one wishes

to

go

until one starts.

But

there are times

when

it is timelytoask

'Now

where

am

I trying to go?'

Moore

has always

reminded

us of

this.

One

thinghehasalwayssoughttokeep beforeusisthe

differ-encebetweenquestionsasto

what

is

actuallythe case

and

questions asto

what

itis

logicallypossibleshould bethecase, the

meanings

of

our

words

being

what

theyare.In

him

too

we

finda habitofthought

which,carriedfurther

by

Wittgenstein,led to

enormous

advances

the study of the

meaning

of general terms

by

consideration of

concretecases.

I

hope

Professor

Wisdom

was

rightin thinking that this

book was

worth

publishing.ItconsistsoftwentylectureswhichIdeliveredat

Morley

College in

London

in the winter of 1910-11, thefirst ten

beinggiven before Christmas,andthesecondtenafter.

And

Ithink

I should have

had

less

hope

thatthey were worthpublishing

had

I

not thought(perhaps mistakenly)that,

though

much

of

them

is

no

doubt

'outof date/ yettheyalsocontain

much

which

isas yet

by no

means

outof date.

My

audience were invited aftereach lecture to raise questions

about

what

I

had

said in it,

and

it is to one of the resulting dis-cussionsthatthefirstsentenceofChapter

XV

refers.

The

lectures are

now

printed substantiallyin the

form

in

which

they

were

delivered. I have

made

a

good

many

verbal changes, substitutingforanexpression

which

Iusedinthelecturesanother expression

which

I

now

think expresses

my

meaning

better.

But

I

could not

make

such changes everywhere:

my

-oldterminologystill

appears in

many

places;

and

I have therefor^a^ded footnotes

ex-plaining

where

I

now

thinkittobeincorrect, f

n

Chapters

XIX

and

XX,

however,Ihave

made

more

extensivedie/rations,

though

only

by

omission omission ofseveralpages,

which

seem

to

me

now

both confused

and

confusing

and

notto

make

any'substantialaddition to

what

I

was

saying.Ihave,therefore, I believe,retained the substance

even of these

two

chapters,

and

have

added

an

Appendix

toexplain

what seem

to

me

tobe thechief defects in

what

I haveretained.

I

am

wellawarethatthere area

good

many

positivemistakes in

what

ishere printed;

and

thereisbesidesa

good

dealofrepetition,

since I often repeated atthe beginning ofalecturepart of

what

I

had

said inthe precedingone, hoping, in

some

cases, to

make

my

meaning

clearer.

There

are

two

matters about

which

I should have

added

foot-notes,

had

I noticed

them

earlier;

and

I should like to mention

them

briefly here.

The

first istheview

which

I express

on

p. 128, thatit is possible that

some

material objects occupy merelypoints

orlines orareas. This

now

seemsto

me

to be a completemistake :

nothing,Ishouldsay,can

be

properlycalled either amaterial thing or a part of a materialthing,unlessitoccupies a

volume

though, of course, the

volume

may

beextremelysmall.Thispointis,ofcourse,

(6)

xii

PREFACE

connected with

my

mistake (pointedout

on

p. 34, note 2) in sup-posingthata surfacecan

be

properlycalled a "part" of a material thing.

The

secondpointabout

which

Ioughttohave

added

a

foot-noteconcerns therelationbetween

what

Isayaboutpropositions in ChapterIII

and what

Isayabout

them

in Chapter

XIV,

pp. 265-6,

and

againin

XVII,

p. 309. InIII, p. 56, 1say ''Therecertainlyare in the Universe such things as propositions", whereas in

XIV

(p. 256)IsaythatI

am

recommending

aview abouttheanalysisof

belief

which

may

beexpressed

by

saying

"There

simplyare

no

such

things as propositions",

and

in

XVII

(p. 309) I say "I don't

now

believe thatthere aresuchthings aspropositions at all".

Now

this looksasif,

when

Iwrote

XIV

and XVII,

I

had abandoned

the very

view

which

inIII I

had

declaredtobecertainlytrue;

and

certainly

I had, ifin III I

had

been usingthe expression 'Thereare such

thingsas propositions' inthe

same

sensein

which

I

was

usingitin

XIV

and

XVIL

But

I

now

feeldoubtfulwhetherinIII I

had

been

usingthatexpressionmerelyin thatsense. Ithinkitispossible that

in IIII

was

usingit,partly atleast,insuch asensethatthe truthof

what

it expresses

would

follow

from

the

mere

fact that such ex-pressionsas'Ibelievirthe proposition thatthesunislargerthanthe

moon*

are perfectly correct

ways

of expressing something

which

is

often true astfyeycertainly are;whereasin

XIV

and

XVII

I

was

using 'There are suthTthings as propositions* in a

way

which

is

perhaps

more

doubtfullycorrect,

namely

insucha

way

thatit

would

notexpress a truth unless suchexpressionsas'I believethe

propo-sitionthatthesunislargerthanthe

moon'

canbecorrectlyanalysed

in acertain

way

which

isaverydifferent usage.

Itis perhaps

worth

mentioning that Chapters

I-X

are the

'un-published writings' ofmine, to

which Lord

Russell refers in the Prefaceto

The

Problems ofPhilosophy.

I should like

finally to acknowledge very gratefully

my

obli-gations to the Editor of the

Muirhead

Library, Professor

H. D,

Lewis.

He

not only took

upon

himself the labour ofsuggesting

titlesfor

my

Chapters titles

which

I

was

only too gladtoadopt,

with one or

two

slight alterations;

he

also

made

such

alterations

atthe beginning ofeach lecture as

were

necessary to

adapt it for

book-form

; and,finally,

by

taking the trouble toread through the

whole

of the page-proofs,

he

discovered misprints

which had

escaped

my

notice

and which would

have disfigured the book.

WHAT

IS

PHILOSOPHY

?

Iwant,asastart,to try togive

you

a general ideaof

what

philosophy

is: or,inother words,

what

sortof questionsitisthatphilosophers

are constantlyengagedindiscussing

and

tryingtoanswer. I

want

to

beginin this

way

for

two

reasons. Inthefirstplace,

by

doingthis, I

shall

be

giving

you

some

idea of

what

the problems are

which

I

myself

mean

todiscuss intherestofthiscourse.

And,

inthesecond

place, I thinkitis the best

way

ofbeginning any discussion of the

main

problems of philosophy.

By

attemptingto

give, first ofall, a

general sketch oroutlineof the

whole

subject,

you

point out

how

the differentseparateproblemsareconnected withoneanother

and

can

give abetteridea oftheirrelativeimportance.

I

am

going, then, first ofall to try tp give a description of the

wholerangeof philosophy.

But

thisisnotatallaneasythingto do. Itisnoteasy, because,

when

you

come

to lookintothe matter,

you

find that philosophershavein fact discussedan

immense

varietyof different sortsof questions;

and

itisverydifficultto giveanygeneral

description,

which

will

embrace

allof thesequestions,

and

alsovery

difficulttoarrange

them

properly inrelation tooneanother.Icannot

hope

really to

do

more

thanto indicateroughlythe

main

sorts of questionswith

which

philosophersare concerned,

and

topoint out

some

of the

most

important connections between these questions.

Iwill try to begin

by

describing those questions

which seem

to

me

to

be

themostimportant

and

the

most

generally interesting,

and

will

then go

on

tothose

which

aresubordinate.

To

beginwith,then,itseemsto

me

thatthe

most

important

and

interestingthing

which

philosophershavetried to

do

is

no

lessthan

this;

namely

:

To

give a generaldescription^thewfypleofthe Uni-verse, mentioningalltiie

*

; ..

variouskinds of things arerelated tooneanother. Iwillcallallthis;

(9)

hence willsay that the first

and most

important

problem

of

philo-sophyis:

To

givea general description of thewholeUniverse.

Many

philosophers (though

by no means

all)have, Ithink, certainly tried

to givesucha description:

and

the verydifferentdescriptions

which

different philosophershavegiven are,I think,

among

the

most

im-portant differences between them.

And

the

problem

is, it

seems

to

me, plainlyone

which

is peculiar to philosophy.

There

is

no

other science

which

tries to say:

Such and

such kinds of things are the

only kinds of thingsthatthereare inthe Universe, or

which

we know

tobeinit.

And

Iwill

now

try toexplain

more

clearly,

by

means

of examples,exactly

what

I

mean

by

thisfirst

problem

exactly

what

I

mean

by

a general description of the whole Universe.Iwilltry,that

is, tomentionthe

most

importantdifferences

between

the

descrip-tions given

by

different philosophers.

And

I wish, for a particular

reason, to begin in a particular way.

There

are, it

seems

to

me,

certainviewsaboutthe nature of the Universe,

which

areheld,

now-a-days,

by

almosteverybody.

They

aresouniversallyheld thatthey

may, Ithink, fairlybe calledtheviewsof

Common

Sense. I

do

not

know

that

Common

Sense can

be

said to have

any

views aboutthe wholeUniverse:

none

ofits views, perhaps,

amount

tothis.

But

it

has, I think, very definiteviews tothe effect that certain kindsof thingscertainly are inthe Universe,

and

asto

some

ofthe

ways

in

which

these kinds of thingsare related toone another.

And

I wish

to begin

by

describing these views,becauseit

seems

to

me

that

what

is

most

amazing

and most

interestingabouttheviewsof

many

philo-sophers,isthe

way

in

which

theygo

beyond

orpositivelycontradict theviews of

Common

Sense:theyprofess to

know

that there arein

theUniverse

most

importantkinds ofthings,

which

Common

Sense

doesnotprofess to

know

of,

and

alsotheyprofessto

know

that there are not in theUniverse(or,atleast,that,ifthereare,

we

do

not

know

it), things of the existence of

which

Common

Senseis

most

sure, I

think, therefore,

you

willbestrealise

what

these philosophical

des-criptionsof theUniversereallymean,

by

realising

how

verydifferent theyare

from

theviewsof

Common

Sense

how

far,in

some

points,

theygo

beyond

Common

Sense,

and

how

absolutely, in others,they

contradictit.Iwish,therefore, tobegin

by

describing

what

Itake to

bethe

most

important viewsof

Common

Sense:things

which

we

all

rommonly

assume

tojbe trueaboutthe

U^erse^

and which

we

are

gurediat

tobetjueaEoutit.

WHAT

IS

PHILOSOPHY?

-

We

know,for instance, thatthereare

upon

the

sur-faceoftheearth, besides our

own

bodies, the bodies ofmillions of other

men

;

we

know

that there arethe bodies ofmillions of other

animals; millions of plants too; and, besides all

these, an even greater

number

of inanimateobjects mountains,

and

allthe stones

upon

them,grains of sand, different sorts of minerals

and

soils, all

the drops ofwater in rivers

and

inthe sea,

and

moreover ever so

many

different objectsmanufactured

by

men

;houses

and

chairsand

tables

and

railway

all thatis initor

asit seems tous, is absurdly

small in comparison with the whole material Universe.

we

now

believe about the materialUniverse:itissurely

Common

Senseto believeit all. But,

as

you

know, there

was

atime

when

itwas

by no means

Common

Senseto believe

some

of these things:there

was

atime

when

nobody

believed

some

of them.

There was

a time

when

there were not nearlyso

many men

upon

the earthasthere are

now

;

and

when

those

who

were

upon

itdidnot

know

how

many

there were.

They

believed only in the existence of a comparatively small

number

of

human

bodies besidetheir

own

;ofa comparatively small

number

of animals

and

plants;

and

they

had no

idea

how

largethesurfaceof the earth

was.

They

believed, too, thatthe heavenly bodieswere small

com-pared to the earth,

and

at comparatively short distances

from

the earth. But I think I

am

rightin saying

we

now

believe that these primitive views aboutthe material Universewere certainly wrong.

We

should say that

we

know

thattheywere

wrong

:

we

have

dis-covered that they were

wrong: and

this discovery is part of our

progressinknowledge.

But

thoughtherearethussomethingsabout

which

the'dews of

Common

Sense have changed:yet,sofar as

con-cerns the point that there are in the Universe a great number of materialobjects,ithas,sofaras

we

know, remainedthe same.

So

far

as

we

know,

men

have believed this almost as long as they have

believed anything: theyhave always believed inthe existenceofa

(11)

SOME MAIN PROBLEMS

But,now,besides materialobjects, we^b^Levejlsothiatthere are

in the Universe certain

phenomena

very different

from

material

TJEjje^^

we

.men, Besides having bodies,

*^6

Haye^mm&;

and

one of the chief things which

we

mean,

by

saying

we

have winds, is, I think, this:

jiai^lYi foat

we

perform

certainjoaentalacts oracts ofspaciousness^

That

istosay,

we

see"'

and

hearandfeel

and remember

and imagine andthink

and

believe

and

desireandlike

and

dislikeandwill

and

love

and

areangry

and

afraid, etc.

These

thingsthat

we

do

are all of

them

mental acts

acts of

mind

or actsofconsciousness: whenever

we

do anyofthem,

we

areconscious ofsomething: each of

them

partly consists inour

being consciousofsomethingin

some

way

orother:

and

itseemsto

me

thatthe thingof

which

we

are

most

certain,

when we

say

we

are certain that

we

have minds,isthat

we

dothese things that

we

per-formtheseactsof consciousness.

At

allevents

we

are certain that

we

do

perform

them and

that these acts are somethingvery different

frommaterial objects.

To

hearisnotitself*materialobject,however

closelyit

may

berelated to certain material objects;

and

so

on

with

all the rest seeing, remembering, feeling, thinking, etc.

These

things, these acts of consciousness are certainly not themselves materialobjects.

And

yet

we

are quite certain thatthereare

immense

numbers

of

them

in the Universe. Every one ofus performs

im-mense numbers

of

them

everyday

and

alldaylong:

we

are

perpetu-ally seeing different things, hearing different things, thinking of different things,

remembering

different things.

We

ceasetoperform

them

only while

we

are asleep,withoutdreaming;

and

evenin sleep,

so longas

we

dream,

we

areperformingactsof consciousness.

There

are,therefore, inthe Universeatany

moment

millionsofdifferent actsofconsciousnessbeingperformed

by

millionsofdifferent men,

and

perhapsalso

by

many

kinds ofanimals. It is, Ithink, certainly

Common

Sensetobelieve allthis.

So

far,then,

we

haveseenthat

Common

Sensebelieves thatthere are inthe Universe,atleast

two

differentkinds ofthings.

There

are,

tobeginwith,

enormous numbers

ofmaterial objects;

and

thereare

alsoa verygreat

number

ofmentalactsoractsof Consciousness.

But

Common

Sensehasalso, Ithink, certainverydefiniteviewsas tojthe

way

inwhichthese

two

kinds of

thingsarerelated toone an-other.But, before

I

explain

what

theseviewsare,

Tmust

fcratmention something which

we

believe tobetrue of absolutelyallthematerial objectswhichIhave mentioned and, indeed, not only of

them

but

(12)

WHAT

IS

PHILOSOPHY?

We

believe, infact,ofallmaterialobjects,thateachof

them

is

any

given

And

by

sayingthattheyareall of

them

in space,

we

mean,

I think,atleast

two

things.

We

mean,inthefirstplace, that

eachof

them

is,atanygiven

moment,

at

some

definitedistancehym,

^Jjh^rest. It

may

be

impossible practically to measure all these distances,orindeedto

measure

anyof

them

absolutelyexactly:but

we

believe that all of

them

could theoretically be measured,

and

expressed as so

many

miles or feet or inches, or such

and

such a fraction of

an

inch,

down

to those objects

which

are absolutely

touching one another,

and

between

which

thereforethedistanceis

nothing at all.

We

believe, for instance, that the earthis (roughly

speaking) so

many

millions of miles distant

from

the sun in one direction,

and

many

more

millions ofmiles distant

from

the pole-star in another;

and

that just as there is, at

any

given

moment,

a

definite distance between the sun

and

the earth,

and

between the pole-star

and

theearth, so thereisalso adefinitedistance between

the

sun and

the pole-star,

and

similarly between any one of the

heavenlybodies

and

alltherest.

And

so toobetweenallthe bodies

on

the surface of theearth, oranypartsof thesebodies:any

two

of

them

are,at

any

given

moment,

eithertouching oneanother, orelse at

some

definitedistance

from

oneanother a distance

which

can

be

roughlyexpressedasso

many

miles orfeetorinches orfractionsof

an

inch.

We

believe, then, thatitistrueofallmaterialobjects that

eachis,at

any

given

moment,

at

some

definitedistance

from

allthe

rest. Thisisoneof the things

which

we mean

by

sayingthattheyare

allin space.

But

we

mean, I think,alsothateachis distant

from

all

therest in

some

direction or other:in

some

oneor other of a quite

definiteset ofdirections.

And

what

thisdefinite setofdirectionsis,

can,Ithink, beeasilyexplained.

We

all

know

theshapeofthefigure

which

is calleda sphere theshapeofaperfectly

round

ball.

Now

from

the centre of a sphere astraight linecan

be

drawn

toeach of the points

upon

itssurface.

Each

of thesestraight lines,

we

should

say,ledinadifferent direction

from

the centre:thisis

what

we mean

by

adirection.

And

moreoverthereare,

we

shouldsay,absolutely

no

directionsin

which

it ispossibleto

move

from

the centreinastraight

line exceptalong oneor other of these straight lines; if

you

areto

move

inastfaight line

from

the centre ofasphereatall,

you must

go

towardsoneor other of the points

on

itssurface;

and

thisis

what

I

meant by

speaking of a quil;e definite set of directions: all the

(13)

given point

form

a quitedefinite set;namely,

you must

goalong

one

or other of thestraight linesleading

from

that pointto

some

point

on

the surfaceofa sphere of

which

itisthecentre.

The

secondthing,

then,

which

Isay

we

believeaboutallmaterial objects:isthat

start-ing

from

anypoint

on any

oneofthem,alltherestwilllie

upon

one

or other ofthis definite setofstraightlines. If

you

considerallthe straightlines

which

lead

from

anypointtoallthedifferentpoints

on

thesurfaceofasphere enclosingit,absolutelyevery material object in theUniverse will, at

any

given

moment,

lie

on

one or other of thesestraightlines;itwilllieat

some

distanceorother alongoneor

other ofthem.

There

is,

we

shouldsay,

no

other position in space

which

any material object could occupy; these straight lines will

passthroughevery position in space;sothat,ifanobjectisinspace

atallit

must

be

on

one or other ofthem. This,therefore, is

one

of the things

which

we

mean

by

saying that all material objects are situated in space.

We

mean,

that is,

when we

talk ofthe space in

which

material objectslie

and

move, a spacein

which

there are

no

otherdirections in

which you

can go

from

any point, except those

which

I have specified.

We

do, I think, certainly hold that all the

materialobjectsIhave mentioned, dolieinsucha space:that

from

any

oneof

them

alltherest

must

atany

moment

lieinoneor other

of thesedirections.

And

when we

talkof'material objects',

we

mean,

I think, as arule, only to includeunderthis description objects of

which

thisistrue.

But, now, I introduced this account of

what

we

believe about

materialobjects, inordertoexplain

some

quite definiteviews aboutthe

way

in

which

and

Iwish

now

tostate

what

theseviewsare.

We

And why

I

introduced

was

inorderto

make

more

clear in

what

sense

we

believe actsof consciousnesstobeattachedto certain materialobjects.

We

believe, Ithink, thatouractsof consciousness

allthose

which

we

perform, so longas

we

are alive areattached toourbodies, inthe sensethatthey occurinthe

same

places in

which

ourbodiesare.

We

alldo,Ithink,constantly

(14)

WHAT

7

most

philosophershaveheldthat,

on

thecontrary, actsof conscious-ness

do

not occurinanyplaceatall thattheyare,

simply,nowhere notin space. Butthat

we

all do

commonly

assumeit, thatitis a belief of

Common

Sense, is, I think, pretty plain. I believe, for

instance, that

my

actsof consciousness aretaking place

now

in this

room,

where

my

body

is.

At

the present

moment

I

am

hearing

and

seeing

and

thinking here, in this room.

And

when, just now, I

travelled

up

to Waterloo

by

train, I believe that

my

mind

and

my

acts of consciousness travelled with me.

When

the train

and

my

body

wereatPutney,I

was

thinking

and

seeingatPutney.

When

the train

and

my

body

reached

Clapham

Junction, I

was

thinking

and

seeing at

Clapham

Junction.

And

so

on

with all the otherplaces

which

Ipassed through.

We

all, I

i^y^j^qamcmLv

assume

inthis~

*

do

not

mean

to

"ffiaf

we

nave anydefiniteideaas to exactlywhereinourbodies our

actsof consciousness takeplace.Idonot think

we

have.

We

should not be prepared to saywhether they all took place at exactly the

same

spotinourbodies orwhetherdifferent actstook placeat

differ-ent spots; nor should

we

be preparedto assign anyparticularspot

as the spot at

which

a particular acttook place. All that

we

do, I

think, believewithcertaintyisthattheyalldotake place

somewhere

or otherinourbodies.

At

all events

we

allconstantlytalk as if

we

believedthis.

And

I

may

illustratetheforceofthisbelief

which

we

now

have,

by

contrastingitwith a different belief

which was

for-merlyheld.

Some

savages, Ibelieve, usedtoholdthat, sometimes

when

a

man

was

dreaming,his

mind

orsoulusedto leave his

body

and

go to

some

other place

and

watch

what was

going

on

inthat place:that,therefore, whilehe

was

asleep,his actsof consciousness

might betaking placeat

some

place otherthanthat

where

his

body

was.

Now

IthinkI

am

right in

sayingthatitis

no

longer

Common

Senseto believethis.

We

commonly

believe

nowadays

that,so long

as

we

arealive,

we

can, atleastnormally, only think

and

see

and

hear

and

feel,whereourbodiesare.

We

believe,atleast,thatan

immense

number

ofactsof consciousnessare attached,each ofthem,to

some

particularbody,inthe sensethatthey occur

somewhere

or otherin that body.

My

acts of consciousness takeplace in

my

body; and

yourstake placeinyours:

and

our

minds

(generally,atleast)go with

us, wherever ourbodiesgo.

We

believe, then, I think, that

many

acts of consciousness are attached to particular material objects, inthe sense thatthey take

(15)

place where thoseobjects are.

But

I

do

not

mean

tosaythat thisis

theonlysensein

which

we

believe

them

tobeattachedto particular material objects, ^gealso believe, jno doubt,that

manj

oftheicaare

degenden^

occurinl>ur bodies.

For

instance,

1 onlysee,

when

certainchangestakeplace in

my

eyes;Ionlyhear,

when

certain changes take place in

my

ears; only think, perhaps,

when

certainchangestake placein

my

brain.

We

certainly believe that

many

acts of consciousnessareattachedto particularbodiesin

this

way

also.Butthe simplest

and most

universal relation

which

we

believe toholdbetweenacts of consciousness

and

particular bodies

is, I think, the one I have mentioned namely, that they occur

wherethosebodiesare.

We

believe,then, that actsof consciousness are attachedto

some

material objects.

But

we

believe, Ithink,

no

less certainly, that to

the vastmajority of material objects, no acts of consciousness are attached.

We

believethat theyare attached to thelivingbodies of

men

millionsofdifferent

men

and, perhaps,of

most

animals;so

thatthereis no lack ofacts of consciousness inthe Universe*

But

nevertheless to thevast

mdority

of material pbjgftftvt frqlieve,

JT

'

We

aresurethat chairs

and

tables

and

_

dmojinlatos

and

stone^donotreallyseeor hear orfeelor think orperform anyothermentalacts:

we

aresurethat

theyarenot conscious.

We

are sure too that thesun

and

moon

and

stars

and

eartharenot conscious that

no

consciousactsareattachedtothem, inthe sensein

which

ourconsciousactsareattachedtoourbodies:

they do not feel or hear or see, as

we

do. This, then, is one very

importantthing

which

we

believeastotherelationbetweenactsof consciousness

and

material objects: namely, that

among

the vast

number

of material objects inthe Universethere arecomparatively

few

to

which

actsot'consciousnessareattached:inother

worcb^lw

farthe greater

number

of the materialobjects' inthe Universeare unconscious. This, I think,

may

fairly be said to

be

the view of

Common

Sense nowadays. But this is another point in regard to

which

the presentviewof

Common

Sensediffersa

good

deal

from

what

it oncewas.

There

was, itseems pretty certain, atime

when

most

men

believedthat actsof Consciousness were attachedto logs ofwood,

and

stones,

and

trees,

and

tothesun

and

moon

and

many

other objects.

They

believedthat spirits were at various times

m

theseobjects;

and

thatwhile thespiritswereinthem,actsof

con-sciousness often took placeinside

them:

the spirit heard

and saw

and

thoughtinsidethe log ofwood,

(16)

and

think inside our bodies.

There

was, then, a time

when

men

commonly

believed that consciousness

was

(for a time, at least)

attachedto

many

bodies,

which

we now

believetobeunconscious.

But

even then, so far as I know, they always believed that there

were, atanygiventime,

many

places inthe Universe in

which

no

acts ofconsciousness

were

goingon.

We,

Ithink,onlygo

much

far-therthanthis:

we

believethat, atanygiventime,the

number

of spots

in

which no

act of consciousnessistakingplaceisimmenselylarger

thanthat ofthose in

which an

actof consciousnessistakingplace.

This,therefore,isonething

which

we

believewithregardtothe relationbetween consciousness

and

material objects.

But

thereare, Ithink, also

two

others

which

deservetobe mentioned.

The

firstof these is this.

We

believe that

we

are at certaintimes conscious of certainmaterialobjects:

we

see,

and

feel,

and

think ofthem.

But

we

believewiththeutmostcertainty thatthese materialobjectscan

and

do

continueto exist even

when

we

are not conscious ofthem.

We

are, for instance, atthis

moment

seeingcertain materialobjects in thisroom.

But

we

believethattheywillcontinue toexist,even

when

we

haveallgone

away and

W*

may,

incteed, say

of

These

three characteristics are not, I think, sufficient to~3eSneTir

may

be

otherobjects,

which

possessallthree

and

yetarenotmaterialobjects.

But

theyare, I think,three of the

most

importantcharacteristics

which

materialobjectshave;

and

we

shouldnotcallanything a materialobject,unless

we

meant

to assert thatit

had

allthree.

A

secondthing, then,

which

we

believeabouttherelationof con-sciousnesstomatter,isthatmatteris

(17)

10

SOME MAIN PROBLEMS

ness ofit thatitexistseven

when

we

are not conscious ofit ;

and

we

believe, too, thatthere are existing atany

moment many

more

material objects, of

which no

man

or animal is conscious, than material objects of

which

we

are conscious.

And

the third thing

which

we

beKeve abouttherelationofconsciousness tomatteristhe

following.

We

believernamely,

thatthereprobably

was

atime

when

therewere noactsofconsciousness attachedtoanymaterialobjects

on

ther

^wth

:atime,

when

the earth

was

so hotthat

no

livingBeings

couldexist

upon

it

;

and

when

therefore there could

be no

conscious

beings

on

iteither.

And

asregards

human

bodies

and

human

con-sciousness

we

believe, I think, that this is not only probable, but

certain.

We

believethatit isonlyfor acomparatively limitedtime

comparatively limited,

though

amounting, perhaps, to several millionsof years that

men

haveexisted

upon

the earth:beforethat

time, there were

no

bodies

upon

the earth

which

could

be

called

human, and

also

no minds which

could

be

calledthe

minds

of

men

;

though

there

may

have

been minds and

acts ofconsciousness

be-longing to other sorts of animals.

And

just as

we

believethat, at

some

timeinthepast,there

were

probably

no

conscious beingsatall

upon

theearth,

and

certainly

no

beingswith

human

consciousness;

y

we

believe thatthere

mav

fflme atiqifrrinthefuture*

when

this

beso.

We

should not indeed

deny

that, even

when

there

was

no

consciousness

on

the earth,there

may

have

been

conscious beings elsewhere inthe Universe,

on

other planets;

we

shouldriot

deny

thatthere

may

be

some

now

;nor should

we

deny

thatthis

may

still

be

so,

when

(ifever) the time comes,

when

all consciousness

upon

the earthisagain extinguished.

But

we

should, I think,hold that there

may

have been,

and

may

be

again, long periods in the history,ofthe material Universe,during

which no

consciousness

was

attached to any ofthe bodies in it

when

no

conscious acts were

taking place

anywhere

init.

We

believe, thatisto say, that justas consciousnesscertainlyis

now

attachedtocomparatively

few

among

the materialobjectsinthe Universe, so there

may

have beeninthe past

and

may

beagaininthefuture,long periods

when

it

was

orwill

be

attachedto noneat all.

This

is, I think, one beliefof

Common

Sense with regard to the relation of consciousness to material

objects; and, if itbeso, itiscertainlyan important elementinour generalviewof the Universe.

So

far,.then,theelements

which

Ihavetriedtoemphasizeinthe

Common

Senseviewofthe Universe, arethese. Firstly,thatthere certainly are jr^tfce U^Yfflffi?,,*^

We

that they

may

on

other planets be other livingbeings,

which

are conscious.

But

we

should, Ithink,saythatconsciousacts certainly are not attachedtothevast majority of the material objects inthe Universe. Thisis one of our beliefs about therelation of acts of consciousness to material objects.

What

Imean,then,

when

Isaythatallmaterialobjects

them

(19)

either this, orelse, allthree: bothdidexist at

And

I

mean,

too, that to

saythata thing 'didexist'is somethingdifferent

from

sayingthatit

'doesexist' and boththese again

from

sayingthatit'willexist';

and

thateachof thesedifferentstatementsisinfacttrueof

some

things.

Iam, for instance, quite surethattherehave beeninthepast

many

actsof consciousness,bothof

my

andthose ofother

men

; I

am

quite sure that

many

are existing

now; and

I

am

very certain,

though

less certain,that

many

will existinthefuture.

And

sotoo of

materialobjects:

many

haveexisted inthe

past,

many

do

existnow,

and

many

(in all

probability) will existin the future. I say

we

all

commonly

believethatthese thingsareso.

We

believe thatthe three

statements 'It didexist'

; 'Itdoes exist*; 'It will exist': are each of

them

true of

many

materialobjectsand

many

actsof consciousness;

the firsttrue of

some

; the second true of others;

and

Webdieve

Mthat

w^do

really

know

allthese thingsthatIhave mentioned.

We

know

thatthereare

and

havebeen

intheUniversethe

two

kinds ofthings material objectsandactsof consciousness.

We

know

that there are

and

have been in the

Uni-verse

huge numbers

of both.

We

know

that

many

material objects

exist

when

we

are not conscious ofthem.

We

know

that the vast

majorityof materialobjects areunconscious.

We

know

thatthings of

do

which

did not existin the past. Allthese things

we

should, Ithink, certainlysaythat

we

And

moreover

we

believe that

we

know

an

immense

number

ofdetails

about particular material objects

and

acts of consciousness, past, present and future.

We

know

most, indeed, about the past; but a

great dealaboutthe present;

and

much

also(though perhapsthisis

only probable knowledge) about the future. Indeed the sphere of

most

of the special sciences

may

be defined as

being to give us detailed knowledge about

particular objects of the kinds which I

have been trying to define: that is to say, about material objects

abouttheir acts of consciousness,

things

and

things

do not yet

Inthe caseofall thesesciences, thereare,

we

believe, an

immense

number

of things

which

are

now

definitely

known

to be facts; a great

many, which

were formerly believed, but are

now

definitely

known

to be errors;

and

a great

many

we

do not

assume

thatthere is this distinction between

what

we

know, what

we

wronglybelieve,

and

what

we

arestillinignorance about:

and

we

assume

that an

enormous

number

of truths about material

objects

and

theactsofconsciousness of

men

belongtothefirstclass

theclassof things absolutely

known

known,

thatis,

by some

man

on

thesurface oftheearth. All thisis, Ithink, certainly

nowadays

part of thebelief of

Common

Sense aboutthe Universe.

Ihavetried, then, toenumeratecertaingeneralbeliefsaboutthe

Universe,

which

may,Ithink,befairlysaid tobebeliefsof

Common

Sense: beliefs

which

we

almostallofus

nowadays

entertain

;

and

I

do

not

mean

tosaythatthesearethe only views of

Common

Sense aboutthe Universe;butonlythattheyareviews

which

itdoeshold

some of its principal beliefs.

But

now

all of these beliefs taken together do not

amount

to a general description ofthe whole Uni-verse: they are not a generaldescription of thewhole Universe,in the sensein

which

Isaidthatthefirstproblemofphilosophy

was

to giveussuchadescription.

They

consistinsayingthattherecertainly are in the Universe certain large classes ofthings,

and

that these thingsare related toone another in certainways.

But what

they

do

not say, as they stand, is that these large classes of things are the onlyclasses of things

which

are inthe Universe, or

which

we

know

tobeinit:they donot say that everything

which

we know

tobein

the Universe belongsto

one

or other of these classes; they

do

not deny,astheystand, thatthere

may

beinthe Universe, or

may

even

be known

tobeinit,importantclassesof things

which

donotbelong

to

any

of the classes I have mentioned. For instance,

Common

Sensesays,accordingto

me

:

There

areintheUniverse

two

classes of things:

There

arematerial

objects in space, andtherearetheacts of consciousness ofliving

men

and

animate

upon

thesurfaceof the earth. But, in order to convert these statements into a general description of the whole Universe,

we

should have to

add

one or other of

two

things.

We

should havetosayeither:Everythinginthe

Universebelongstooneor otherofthese

two

classes; everythingis

eithera materialobject in space, oranactof consciousness of

some

man

oranimal

on

theearth.

And

this

would

plainly,if

any

onesaid

it,professtobeageneraldescription ofthe whole Universe.

Or

else

we

might say:

Everything

which

we

know

to be in the Universe,

does

belongtooneor other of these

two

classes;

though

there

may

be

in theUniverseotherthings, which

we

donot

know

tobein it.

And

this also, Ithink,mightfairlybesaidtobe an attempttogive a
