Information about Project Gutenberg (one page)
We produce about two million dollars for each hour we work Thetime it takes us
to get any etext selected
searched and analyzed
projected audience is one hundred million readers If our valueper text is nominally estimated at one dollar then we produce $2million dollars per hour this year as we release thirty-six textfiles per month
If these reach just 10% of the computerized population
total should reach over 200 billion Etexts given away this year
The Goal of Project Gutenberg is to Give Away One Trillion EtextFiles by December 31
This is ten thousand titles each to one hundred million readerswhich is only ~5% of the present number of computer users
At our revised rates of production
of that goal by the end of 2001
manage to get some real funding; currently our funding is mostlyfrom Michael Hart's salary at Carnegie-Mellon University
assortment of sporadic gifts; this salary is only good for a fewmore years

old-fashioned materialism can receive no support from modernphysics I think that what has permanent value in the outlook ofthe behaviourists is the feeling that physics is the most
fundamental science at present in existence But this positioncannot be called materialistic
physics does not assume the existence of matter

There are certain occurrences which we are in the habit of

Before considering modern theories

preliminary consider different ways of being conscious

The view here expressed

which I shall be concerned to combat Like Brentano
interested in psychology
the light that it may throw on the problem of knowledge Until
very lately I believed

of knowledge I shall try to make my reasons for this rejection
clear as we proceed It must be evident at first glance that the
analysis of knowledge is rendered more difficult by the
rejection; but the apparent simplicity of Brentano's view of
knowledge will be found
maintaining itself either against an analytic scrutiny or against
a host of facts in psycho-analysis and animal psychology I do
not wish to minimize the problems I will merely observe
mitigation of our prospective labours
is to be analysed
there is no enemy to thinking so deadly as a false simplicity

The view expressed by Brentano has been held very generally
developed by many writers Among these we may take as an examplehis Austrian successor Meinong.* According to him there are threeelements involved in the thought of an object These three he

The first criticism I have to make is that the ACT seems
unnecessary and fictitious The occurrence of the content of athought constitutes the occurrence of the thought Empiricallycannot discover anything corresponding to the supposed act; andtheoretically I cannot see that it is indispensable We say: "_I_

There is a psychological school called "Behaviourists
Trang 28knows" its name because it comes when it is called, and that it
"remembers" its master, because it looks sad in his absence, butwags its tail and barks when he returns That the dog behaves inthis way is matter of observation, but that it "knows" or
"remembers" anything is an inference, and in fact a very doubtfulone The more such inferences are examined, the more precariousthey are seen to be Hence the study of animal behaviour has beengradually led to abandon all attempt at mental interpretation.And it can hardly be doubted that, in many cases of complicatedbehaviour very well adapted to its ends, there can be no
prevision of those ends The first time a bird builds a nest, wecan hardly suppose it knows that there will be eggs to be laid in
it, or that it will sit on the eggs, or that they will hatch into
young birds It does what it does at each stage because instinctgives it an impulse to do just that, not because it foresees anddesires the result of its actions.*
* An interesting discussion of the question whether instinctiveactions, when first performed, involve any prevision, howevervague, will be found in Lloyd Morgan's "Instinct and Experience

an account of the actions of animals without assuming what wecall "consciousness." It has seemed to the behaviourists thatsimilar methods can be applied to human behaviour

such-and-such a thing; examinations are experiments for
discovering such facts But all that is observed or discovered is
a certain set of habits in the use of words The thoughts (if
any) in the mind of the examinee are of no interest to the
examiner; nor has the examiner any reason to suppose even themost successful examinee capable of even the smallest amount ofthought

a sort which the patient would consider wicked; if he had toadmit that he had the desire
so strong that it must force an outlet for itself; hence it
becomes necessary to entertain whole systems of false beliefs inorder to hide the nature of what is desired The resulting
delusions in very many cases disappear if the hysteric or lunaticcan be made to face the facts about himself The consequence ofthis is that the treatment of many forms of insanity has grownmore psychological and less physiological than it used to be.Instead of looking for a physical defect in the brain

It may be true, or it may not So far, that is all we can say
Returning from this digression to our main topic, namely, the
criticism of "consciousness," we observe that Freud and his
followers, though they have demonstrated beyond dispute the
immense importance of "unconscious" desires in determining ouractions and beliefs, have not attempted the task of telling us
what an "unconscious" desire actually is, and have thus investedtheir doctrine with an air of mystery and mythology which forms alarge part of its popular attractiveness They speak always as
though it were more normal for a desire to be conscious, and asthough a positive cause had to be assigned for its being
unconscious Thus "the unconscious" becomes a sort of undergroundprisoner, living in a dungeon, breaking in at long intervals uponour daylight respectability with dark groans and maledictions andstrange atavistic lusts The ordinary reader, almost inevitably,
thinks of this underground person as another consciousness,
prevented by what Freud calls the "censor" from making his voiceheard in company, except on rare and dreadful occasions when heshouts so loud that every one hears him and there is a scandal.Most of us like the idea that we could be desperately wicked if
only we let ourselves go For this reason, the Freudian
"unconscious" has been a consolation to many quiet and
well-behaved persons
I do not think the truth is quite so picturesque as this I
believe an "unconscious" desire is merely a causal law of our
behaviour,* namely, that we remain restlessly active until a
certain state of affairs is realized, when we achieve temporary
equilibrium If we know beforehand what this state of affairs is,
our desire is conscious; if not, unconscious The unconscious
desire is not something actually existing, but merely a tendency
to a certain behaviour; it has exactly the same status as a force
in dynamics The unconscious desire is in no way mysterious; it
is the natural primitive form of desire, from which the other hasdeveloped through our habit of observing and theorizing (oftenwrongly) It is not necessary to suppose, as Freud seems to do,that every unconscious wish was once conscious, and was then, inhis terminology, "repressed" because we disapproved of it On the
Trang 34Page 34
undoubtedly occurs and is important
for unconsciousness of our wishes The usual reason is merelythat wishes are all
known when they are actively noticed Usually
people do not notice
they find current
this theory would lead them to expect We used to be full ofvirtuous wishes

There is one movement
which is not subsequently classified
is the kind of movement which may be called "mechanical"; it isevidently of a different kind from either reflex or voluntary
in some very recondite sense A moth flying into a lamp is not
acting sensibly; no more is a man who is in such a hurry to gethis ticket that he cannot remember the name of his destination.Appropriateness is a complicated and merely approximate ideafor the present we shall do well to dismiss it from our thoughts
As James states
"An outside observer, unable to perceive the accompanying
consciousness, might be wholly at a loss to discriminate betweenthe automatic acts and those which volition escorted But if thecriterion of mind's existence be the choice of the proper meansfor the attainment of a supposed end, all the acts alike seem to
be inspired by intelligence, for APPROPRIATENESS characterizesthem all alike
Trang 37Page 37
of the outside observer
The physiologist can discover that both depend upon the nervoussystem
voluntary depend upon higher centres in the brain than those thatare reflex But he cannot discover anything as to the presence or
absence of "will" or "consciousness
movements We may then distinguish "vital" from mechanical
movements by the fact that vital movements depend for their
causation upon the special properties of the nervous system
while mechanical movements depend only upon the properties whichanimal bodies share with matter in general
There is need for some care if the distinction between mechanicaland vital movements is to be made precise It is quite likely
that
their movements from the laws of chemistry and physics It is
already fairly easy to see how chemistry reduces to physics
how the differences between different chemical elements can beaccounted for by differences of physical structure
constituents of the structure being electrons which are exactlyalike in all kinds of matter We only know in part how to reducephysiology to chemistry
that the reduction is possible If we suppose it effected
would become of the difference between vital and mechanical
Trang 38Page 38
movements?
Some analogies will make the difference clear A shock to a mass
of dynamite produces quite different effects from an equal shock
to a mass of steel: in the one case there is a vast explosion
while in the other case there is hardly any noticeable
disturbance Similarly
a large rock poised so delicately that a touch will set it
crashing down into the valley
firm that only a considerable force can dislodge them What isanalogous in these two cases is the existence of a great store ofenergy in unstable equilibrium ready to burst into violent motion
by the addition of a very slight disturbance Similarly
requires only a very slight expenditure of energy to send a
post-card with the words "All is discovered; fly!" but the effect
in generating kinetic energy is said to be amazing A human bodylike a mass of dynamite

disturbance which is physically very small
word In all such cases the reduction of behaviour to physicallaws can only be effected by entering into great minuteness; solong as we confine ourselves to the observation of comparativelylarge masses
cannot be determined Physicists distinguish between macroscopicand microscopic equations: the former determine the visiblemovements of bodies of ordinary size
occurrences in the smallest parts It is only the microscopic
equations that are supposed to be the same for all sorts of

matter The macroscopic equations result from a process ofaveraging out

to produce movements out of proportion to the proximate cause.Movements produced in this way are vital movements
mechanical movements are those in which the stored energy of aliving body is not involved Similarly dynamite may be explodedthereby displaying its characteristic properties

mechanical movements
Mechanical movements are of no interest to the psychologist
it has only been necessary to define them in order to be able toexclude them When a psychologist studies behaviour
vital movements that concern him We shall
ignore mechanical movements
remainder
The next point is to distinguish between movements that areinstinctive and movements that are acquired by experience Thisdistinction also is to some extent one of degree Professor Lloyd
