00:12
I'm going to talk about consciousness.
0
12464
2593
Govorit ću o svijesti.
00:15
Why consciousness?
1
15081
1456
Zašto o svijesti?
00:16
Well, it's a curiously neglected subject,
2
16561
2802
Pa, to je začudno zanemarena tema,
00:19
both in our scientific and our philosophical culture.
3
19387
3540
i u našoj znanstvenoj i u našoj filozofskoj kulturi.
00:22
Now why is that curious?
4
22951
1248
Zašto je to začudno?
00:24
Well, it is the most important aspect of our lives
5
24223
3486
Pa, to je najvažniji aspekt naših života
00:27
for a very simple, logical reason,
6
27733
1934
iz vrlo jednostavnog, logičkog razloga,
00:29
namely, it's a necessary condition on anything
7
29691
2373
naime, nužni uvjet da bi išta
00:32
being important in our lives that we're conscious.
8
32088
2453
bilo važno u našim životima, jest da smo svjesni.
00:34
You care about science, philosophy, music, art, whatever --
9
34565
3135
Stalo vam je do znanosti, glazbe, umjetnosti, čega god --
00:37
it's no good if you're a zombie or in a coma, right?
10
37724
3454
no to ne vrijedi ako ste zombi ili ako ste u komi, zar ne?
00:41
So consciousness is number one.
11
41202
2320
Zato je svijest broj jedan.
00:43
The second reason is that when people do
12
43546
2444
Drugi je razlog to što, kad se ljudi konačno počnu
00:46
get interested in it, as I think they should,
13
46014
2292
zanimati za svijest, kao što smatram da trebaju,
00:48
they tend to say the most appalling things.
14
48330
2827
imaju tendenciju govoriti najužasnije stvari.
00:51
And then, even when they're not saying appalling things
15
51181
2620
I onda, čak i kad ne govore najužasnije stvari
00:53
and they're really trying to do serious research,
16
53825
2334
i kad zaista pokušavaju ozbiljno istraživati,
pa, bilo je sporo. Progres je bio spor.
00:56
well, it's been slow. Progress has been slow.
17
56183
3117
00:59
When I first got interested in this, I thought, well,
18
59324
3116
Kada me je ovo počelo zanimati, mislio sam, pa,
01:02
it's a straightforward problem in biology.
19
62464
2182
to je jednostavan problem u biologiji.
01:04
Let's get these brain stabbers to get busy and figure out
20
64670
2473
Neka oni što bodu mozgove počnu raditi i shvate kako
01:07
how it works in the brain.
21
67167
860
to radi u mozgu.
01:08
So I went over to UCSF and I talked to all
22
68051
2000
Tako sam otišao u UCSF i razgovarao sa
svim neurobiolozima ondje,
01:10
the heavy-duty neurobiologists there,
23
70075
1769
01:11
and they showed some impatience,
24
71868
1552
i pokazali su nestrpljenje,
01:13
as scientists often do when you ask them embarrassing questions.
25
73444
3359
kao što to znanstvenici često čine kada im postavljate neugodna pitanja.
01:16
But the thing that struck me is, one guy said in exasperation,
26
76827
3734
No, ono što me iznenadilo je, jedan je čovjek ogorčeno rekao,
01:20
a very famous neurobiologist, he said, "Look,
27
80585
2143
jako poznat neurobiolog, rekao je, "Gledaj,
01:22
in my discipline it's okay to be interested in consciousness,
28
82752
3399
u mojoj disciplini u redu je interesirati se za svijest,
01:26
but get tenure first. Get tenure first."
29
86175
3543
no prvo moraš dobiti poziciju. Prvo dobij poziciju."
01:29
Now I've been working on this for a long time.
30
89742
2694
Radio sam na ovome dugo vrijeme.
01:32
I think now you might actually get tenure
31
92460
1954
Mislim da bi sada i mogli dobiti poziciju
01:34
by working on consciousness.
32
94438
1334
radeći na svijesti.
01:35
If so, that's a real step forward.
33
95796
2522
Ako je tako, onda je to pravi korak unaprijed.
01:38
Okay, now why then is this curious reluctance
34
98342
2881
Zašto postoji taj čudan otpor
01:41
and curious hostility to consciousness?
35
101247
1874
i čudno neprijateljstvo prema svijesti?
01:43
Well, I think it's a combination of two features
36
103145
2706
Mislim da je to kombinacija dvije odlike
01:45
of our intellectual culture
37
105875
1881
naše intelektualne kulture
01:47
that like to think they're opposing each other
38
107780
2502
koje vole misliti da su suprotne jedna drugoj,
01:50
but in fact they share a common set of assumptions.
39
110306
3599
no u stvari dijele isti set pretpostavki.
01:53
One feature is the tradition of religious dualism:
40
113929
3938
Jedna odlika je tradicija religioznog dualizma:
01:57
Consciousness is not a part of the physical world.
41
117891
3301
Svijest nije dio fizičkog svijeta.
02:01
It's a part of the spiritual world.
42
121216
1903
Ona je dio duhovnog svijeta.
02:03
It belongs to the soul,
43
123143
1512
Pripada duši,
02:04
and the soul is not a part of the physical world.
44
124679
3272
a duša nije dio fizičkog svijeta.
02:07
That's the tradition of God, the soul and immortality.
45
127975
3007
To je tradicija Boga, duše i besmrtnosti.
02:11
There's another tradition that thinks it's opposed to this
46
131006
2081
Postoji i druga tradicija koja misli da je
02:13
but accepts the worst assumption.
47
133111
2080
suprotna, no prihvaća najgoru pretpostavku.
02:15
That tradition thinks that we are heavy-duty scientific materialists:
48
135215
4054
Ta tradicija misli da smo tvrdi znanstveni materijalisti:
02:19
Consciousness is not a part of the physical world.
49
139293
3441
Svijest nije dio fizičkog svijeta.
02:22
Either it doesn't exist at all, or it's something else,
50
142758
2622
Ili uopće ne postoji, ili je nešto drugo,
02:25
a computer program or some damn fool thing,
51
145404
2626
kompjuterski program ili neka druga stvar,
02:28
but in any case it's not part of science.
52
148054
3171
ali u svakom slučaju nije dio znanosti.
02:31
And I used to get in an argument that really gave me a stomachache.
53
151249
2184
I ulazio sam u raspravu od koje me trbuh bolio.
02:33
Here's how it went.
54
153457
1595
Išla je ovako.
02:35
Science is objective, consciousness is subjective,
55
155076
4008
Znanost je objektivna, svijest je subjektivna,
02:39
therefore there cannot be a science of consciousness.
56
159108
3303
dakle, ne može postojati znanost svijesti.
02:42
Okay, so these twin traditions are paralyzing us.
57
162435
6480
U redu, dakle, te blizanačke tradicije nas paraliziraju.
02:48
It's very hard to get out of these twin traditions.
58
168939
2844
Vrlo je teško izaći iz tih blizanačkih tradicija.
02:51
And I have only one real message in this lecture,
59
171807
2994
I imam samo jednu pravu poruku u ovom predavanju,
02:54
and that is, consciousness is a biological phenomenon
60
174825
3360
a to je, svijest je biološki fenomen
02:58
like photosynthesis, digestion, mitosis --
61
178209
2865
poput fotosinteze, probave, mitoze --
03:01
you know all the biological phenomena -- and once you accept that,
62
181098
4311
svih bioloških fenomena -- i jednom kad to prihvatite,
03:05
most, though not all, of the hard problems
63
185433
2615
većina, iako ne svi, velikih problema
03:08
about consciousness simply evaporate.
64
188072
2251
vezanih uz svijest, jednostavno nestane.
03:10
And I'm going to go through some of them.
65
190347
2029
I razmotrit ću neke od njih.
03:12
Okay, now I promised you to tell you some
66
192400
2309
U redu, obećao sam da ću vam ispričati neke
03:14
of the outrageous things said about consciousness.
67
194733
2715
od nečuvenih stvari izrečenih o svijesti.
03:17
One: Consciousness does not exist.
68
197472
3576
Prva: Svijest ne postoji.
03:21
It's an illusion, like sunsets.
69
201072
2206
To je iluzija, poput zalazaka sunca.
03:23
Science has shown sunsets and rainbows are illusions.
70
203302
5041
Znanost je pokazala da su zalasci sunca i duge iluzije.
03:28
So consciousness is an illusion.
71
208367
1899
Tako, svijest je iluzija.
03:30
Two: Well, maybe it exists, but it's really something else.
72
210290
3231
Druga: Pa, možda postoji, ali je zapravo nešto drugo.
03:33
It's a computer program running in the brain.
73
213545
3757
To je kompjuterski program u mozgu.
03:37
Three: No, the only thing that exists is really behavior.
74
217326
3790
Treća: Ne, jedina stvar koja zapravo postoji je ponašanje.
03:41
It's embarrassing how influential behaviorism was,
75
221140
3584
Sramotno je koliko je biheviorizam bio utjecajan,
03:44
but I'll get back to that.
76
224748
1331
no vratit ću se na to.
03:46
And four: Maybe consciousness exists,
77
226103
2710
I četvrta: Možda svijest postoji,
03:48
but it can't make any difference to the world.
78
228837
2191
no ne može učiniti nikakvu razliku u svijetu.
Kako bi duhovnost mogla išta pomaknuti?
03:51
How could spirituality move anything?
79
231052
2696
03:53
Now, whenever somebody tells me that, I think,
80
233772
2191
Kad god mi netko to kaže, pomislim,
03:55
you want to see spirituality move something?
81
235987
2266
želiš li vidjeti kako duhovnost nešto pomiče?
Pogledaj, svjesno odlučim podići svoju ruku,
03:58
Watch. I decide consciously to raise my arm,
82
238277
2828
04:01
and the damn thing goes up. (Laughter)
83
241129
2585
i vražja stvar ide gore. (smijeh)
04:03
Furthermore, notice this:
84
243738
3747
Štoviše, primijetite ovo:
04:07
We do not say, "Well, it's a bit like the weather in Geneva.
85
247509
3971
ne kažemo, "pa, to je pomalo kao vrijeme u Ženevi,
04:11
Some days it goes up and some days it doesn't go up."
86
251504
2624
nekada ide gore, a nekada ne."
04:14
No. It goes up whenever I damn well want it to.
87
254152
2631
Ne, ide gore kad god ja želim da ide.
04:16
Okay. I'm going to tell you how that's possible.
88
256807
2286
U redu, reći ću vam kako je to moguće.
Nisam vam još dao definiciju.
04:19
Now, I haven't yet given you a definition.
89
259117
3475
04:22
You can't do this if you don't give a definition.
90
262616
2334
Ne možete to učiniti ako ne date definiciju.
04:24
People always say consciousness is very hard to define.
91
264974
2962
Ljudi uvijek kažu da je svijest jako teško definirati.
04:27
I think it's rather easy to define
92
267960
1859
Ja mislim da ju je lako definirati,
04:29
if you're not trying to give a scientific definition.
93
269843
2185
ako ne pokušate dati znanstvenu definiciju.
04:32
We're not ready for a scientific definition,
94
272052
2256
Nismo spremni za znanstvenu definiciju,
04:34
but here's a common-sense definition.
95
274332
1762
no evo zdravorazumske definicije.
04:36
Consciousness consists of all those states of feeling
96
276118
2778
Svijest se sastoji od svih tih stanja osjećanja
04:38
or sentience or awareness.
97
278920
2044
ili osjeta ili svjesnosti.
04:40
It begins in the morning when you wake up from a dreamless sleep,
98
280988
3534
Počinje ujutro kad se probudite iz sna bez snova,
04:44
and it goes on all day until you fall asleep
99
284546
2445
i nastavlja se cijeli dan dok ne zaspete
04:47
or die or otherwise become unconscious.
100
287015
3174
ili umrete ili na drugi način postanete nesvjesni.
04:50
Dreams are a form of consciousness on this definition.
101
290213
3096
Snovi su oblik svijesti po ovoj definiciji.
04:53
Now, that's the common-sense definition. That's our target.
102
293333
2878
To je zdravorazumska definicija. To je naš cilj.
04:56
If you're not talking about that, you're not talking about consciousness.
103
296235
3477
Ako ne govorite o tome, ne govorite o svijesti.
04:59
But they think, "Well, if that's it, that's an awful problem.
104
299736
3460
Ali oni misle, "Ako je to to, onda je to užasan problem.
05:03
How can such a thing exist as part of the real world?"
105
303220
3934
Kako bi takva stvar mogla postojati kao dio stvarnog svijeta?"
05:07
And this, if you've ever had a philosophy course,
106
307178
2334
A ovo, ako ste ikada imali filozofiju
05:09
this is known as the famous mind-body problem.
107
309536
2727
kao predmet, je poznato kao slavni problem odnosa uma i tijela.
05:12
I think that has a simple solution too. I'm going to give it to you.
108
312287
3239
Mislim da ima jednostavno rješenje. Obrazložit ću vam ga.
05:15
And here it is: All of our conscious states, without exception,
109
315550
3978
Evo ga: Sva naša svjesna stanja, bez iznimke,
05:19
are caused by lower-level neurobiological processes in the brain,
110
319552
5501
uzrokovana su neurobiološkim procesima u mozgu na nižoj razini,
05:25
and they are realized in the brain
111
325077
2157
a ostvaruju se u mozgu
05:27
as higher-level or system features.
112
327258
2310
kao svojstva na višoj razini ili svojstva sustava.
05:29
It's about as mysterious as the liquidity of water.
113
329592
3132
Otprilike je misteriozno kao i tekuće stanje vode.
05:32
Right? The liquidity is not an extra juice squirted out
114
332748
3451
Tekuće stanje nije nešto dodatno što
05:36
by the H2O molecules.
115
336223
1666
H2O molekule proizvode.
05:37
It's a condition that the system is in.
116
337913
2854
To je stanje u kojem se sustav nalazi.
05:40
And just as the jar full of water can go from liquid to solid
117
340791
5138
I kao što staklenka puna vode može ići od tekućeg do krutog
05:45
depending on the behavior of the molecules,
118
345953
2048
ovisno o ponašanju molekula,
tako vaš mozak može ići od stanja u kojem je nesvjestan
05:48
so your brain can go from a state of being conscious
119
348025
2853
05:50
to a state of being unconscious,
120
350902
1616
do stanja svjesnosti,
05:52
depending on the behavior of the molecules.
121
352542
2962
ovisno o ponašanju molekula.
05:55
The famous mind-body problem is that simple.
122
355528
4361
Slavni problem odnosa duha i tijela je toliko jednostavan.
05:59
All right? But now we get into some harder questions.
123
359913
3153
Ali sad nailazimo na neka teža pitanja.
06:03
Let's specify the exact features of consciousness,
124
363090
3420
Specificirajmo točno svojstva svijesti,
06:06
so that we can then answer those four objections
125
366534
2448
tako da možemo odgovoriti na ona četiri prigovora
06:09
that I made to it.
126
369006
1263
koja sam uputio.
06:10
Well, the first feature is, it's real and irreducible.
127
370293
4243
Prvo svojstvo jest da je stvarna i ireducibilna.
06:14
You can't get rid of it.
128
374560
2030
Ne možete je se riješiti.
06:16
You see, the distinction between reality and illusion
129
376614
4147
Razlika između stvarnosti i iluzije
06:20
is the distinction between how things
130
380785
2645
je razlika između toga kako se stvari
06:23
consciously seem to us and how they really are.
131
383454
3850
nama čine i kakve zaista jesu.
06:27
It consciously seems like there's --
132
387328
1852
Čini se kao da postoji --
06:29
I like the French "arc-en-ciel" —
133
389204
1644
kao francuski "arc-en-ciel" --
06:30
it seems like there's an arch in the sky,
134
390872
2174
čini se kao da postoji luk na nebu,
06:33
or it seems like the sun is setting over the mountains.
135
393070
3756
ili se čini kao da sunce zalazi iza planina.
06:36
It consciously seems to us, but that's not really happening.
136
396850
3073
To se nama čini, ali to se zaista ne događa.
06:39
But for that distinction between
137
399947
1903
No to je distinkcija između
06:41
how things consciously seem and how they really are,
138
401874
2477
onoga kako se stvari nama čine i kakve su zaista,
06:44
you can't make that distinction for the very existence of consciousness,
139
404375
4031
ne možete napraviti tu distinkciju za samo postojanje svijesti,
06:48
because where the very existence of consciousness is concerned,
140
408430
3827
zato što, kad se razmatra samo postojanje svijesti,
06:52
if it consciously seems to you that you are conscious,
141
412281
2956
ako se svjesno vama čini da ste svjesni,
06:55
you are conscious.
142
415261
1861
onda ste svjesni.
06:57
I mean, if a bunch of experts come to me and say,
143
417146
3330
Hoću reći, ako mi hrpa stručnjaka priđe i kaže,
07:00
"We are heavy-duty neurobiologists and we've done a study
144
420500
2667
"Mi smo neurobiolozi i istražili smo vas,
Searle, i uvjereni smo da niste svjesni,
07:03
of you, Searle, and we're convinced you are not conscious,
145
423191
2726
07:05
you are a very cleverly constructed robot,"
146
425941
2048
vi ste vrlo pametno konstruiran robot",
ne bih mislio, "pa, možda su oni u pravu".
07:08
I don't think, "Well, maybe these guys are right, you know?"
147
428013
3245
07:11
I don't think that for a moment, because, I mean,
148
431282
2539
Ne bih to ni na trenutak pomislio jer, Descartes je
07:13
Descartes may have made a lot of mistakes, but he was right about this.
149
433845
2886
možda napravio puno pogrešaka, no u ovome je bio u pravu.
07:16
You cannot doubt the existence of your own consciousness.
150
436755
2931
Ne možete sumnjati u postojanje vlastite svijesti.
07:19
Okay, that's the first feature of consciousness.
151
439710
2286
U redu, to je prvo svojstvo svijesti.
Stvarna je i ireducibilna.
07:22
It's real and irreducible.
152
442020
1780
07:23
You cannot get rid of it by showing that it's an illusion
153
443824
3207
Ne možete je se riješiti tako što pokažete da je iluzija
07:27
in a way that you can with other standard illusions.
154
447055
3205
na način na koji to možete s drugim standardnim iluzijama.
07:30
Okay, the second feature is this one
155
450284
2508
Sljedeće svojstvo je ono
07:32
that has been such a source of trouble to us,
156
452816
2441
koje nas je dugo mučilo,
07:35
and that is, all of our conscious states
157
455281
2158
a to je da sva naša svjesna stanja
07:37
have this qualitative character to them.
158
457463
2940
imaju kvalitativan karakter.
07:40
There's something that it feels like to drink beer
159
460427
2381
Postoji nešto kako je to piti pivo
07:42
which is not what it feels like to do your income tax
160
462832
2921
koje je različito od onog kako je to obračunavati porez
07:45
or listen to music, and this qualitative feel
161
465777
3044
ili slušati glazbu, a ovaj kvalitativan osjećaj
07:48
automatically generates a third feature,
162
468845
2537
automatski generira treće svojstvo,
07:51
namely, conscious states are by definition subjective
163
471406
3770
naime, svjesna stanja su po definiciji subjektivna
07:55
in the sense that they only exist as experienced
164
475200
2931
u smislu da postoje samo kao iskustvo
07:58
by some human or animal subject,
165
478155
2171
nekog ljudskog ili životinjskog subjekta,
08:00
some self that experiences them.
166
480350
1849
nekog sebstva koje ih doživljava.
08:02
Maybe we'll be able to build a conscious machine.
167
482223
2359
Možda ćemo moći izgraditi svjestan stroj.
08:04
Since we don't know how our brains do it,
168
484606
2129
Budući da ne znamo kako to naši mozgovi rade,
08:06
we're not in a position, so far, to build a conscious machine.
169
486759
4111
još nismo u poziciji izgraditi svjestan stroj.
08:10
Okay. Another feature of consciousness
170
490894
2751
U redu. Još jedno svojstvo svijesti
08:13
is that it comes in unified conscious fields.
171
493669
4127
je da dolazi u unificiranim poljima svijesti.
08:17
So I don't just have the sight of the people in front of me
172
497820
2332
Tako da nemam samo prizor ljudi ispred mene
08:20
and the sound of my voice and the weight of my shoes
173
500176
2690
i zvuk mog glasa i težinu mojih cipela,
08:22
against the floor, but they occur to me
174
502890
2151
nego se meni oni pojavljuju
08:25
as part of one single great conscious field
175
505065
3458
kao dio jednog jedinstvenog velikog svjesnog iskustva
08:28
that stretches forward and backward.
176
508547
1992
koje se proteže unaprijed i unatrag.
08:30
That is the key to understanding
177
510563
1745
To je ključ razumijevanja
08:32
the enormous power of consciousness.
178
512332
2415
ogromne moći svijesti.
08:34
And we have not been able to do that in a robot.
179
514771
2920
I nismo bili u mogućnosti postići to u robotu.
08:37
The disappointment of robotics derives from the fact
180
517715
2477
Razočaranje robotike dolazi zbog činjenice
08:40
that we don't know how to make a conscious robot,
181
520216
2334
da ne znamo kako napraviti svjesnog robota,
08:42
so we don't have a machine that can do this kind of thing.
182
522574
3025
pa tako nemamo stroj koji je sposoban za takvo što.
08:45
Okay, the next feature of consciousness,
183
525623
2484
U redu, sljedeće svojstvo svijesti,
08:48
after this marvelous unified conscious field,
184
528131
3091
nakon ovog veličanstvenog unificiranog svjesnog iskustva,
08:51
is that it functions causally in our behavior.
185
531246
2769
je da uzročno utječe na naše ponašanje.
08:54
I gave you a scientific demonstration by raising my hand,
186
534039
3179
Dao sam vam znanstvenu demonstraciju podizanjem svoje ruke,
08:57
but how is that possible?
187
537242
1726
no kako je to moguće?
08:58
How can it be that this thought in my brain
188
538992
3740
Kako može biti da ova misao u mom mozgu
09:02
can move material objects?
189
542756
2176
može pomicati materijalne objekte?
09:04
Well, I'll tell you the answer.
190
544956
1477
Reći ću vam odgovor.
09:06
I mean, we don't know the detailed answer,
191
546457
2000
Mislim, ne znamo detaljni odgovor,
09:08
but we know the basic part of the answer, and that is,
192
548481
2678
no znamo osnovni dio odgovora, a to je,
09:11
there is a sequence of neuron firings,
193
551183
2269
postoji niz neuronskih impulsa,
09:13
and they terminate where the acetylcholine
194
553476
3063
i oni završavaju tamo gdje se acetilkolin
09:16
is secreted at the axon end-plates of the motor neurons.
195
556563
2797
izlučuje na krajnjim dijelovima aksona motornih neurona.
09:19
Sorry to use philosophical terminology here,
196
559384
2096
Oprostite što ovdje koristim filozofsku
09:21
but when it's secreted at the axon end-plates of the motor neurons,
197
561504
3947
terminologiju, no kada je izlučen iz krajnjih dijelova aksona motornih neurona,
09:25
a whole lot of wonderful things happen in the ion channels
198
565475
2762
puno se divnih stvari dogodi u ionskim kanalima
09:28
and the damned arm goes up.
199
568261
1882
i prokleta ruka ode gore.
09:30
Now, think of what I told you.
200
570167
2100
Mislite o ovome što sam vam rekao.
09:32
One and the same event,
201
572291
1718
Jedan te isti događaj,
09:34
my conscious decision to raise my arm
202
574033
3011
moja svjesna odluka da podignem ruku,
09:37
has a level of description where it has all of these
203
577068
2771
ima level deskripcije gdje ima sve ove
09:39
touchy-feely spiritual qualities.
204
579863
2122
duhovne kvalitete.
09:42
It's a thought in my brain, but at the same time,
205
582009
2377
Ona je misao u mom mozgu, no istovremeno,
09:44
it's busy secreting acetylcholine
206
584410
1962
zaposlena je izlučivanjem acetilkolina
09:46
and doing all sorts of other things
207
586396
1667
i činjenjem raznih drugih stvari
dok putuje od motornog korteksa
09:48
as it makes its way from the motor cortex
208
588087
2608
09:50
down through the nerve fibers in the arm.
209
590719
2673
do živčanih vlakana u ruci.
09:53
Now, what that tells us is that our traditional vocabularies
210
593416
3792
Ovo nam govori da je naš tradicionalni vokabular
09:57
for discussing these issues are totally obsolete.
211
597232
3360
za raspravljanje o ovim stvarima potpuno zastario.
10:00
One and the same event has a level of description
212
600616
3233
Jedan te isti događaj ima level deskripcije
10:03
where it's neurobiological, and another level of description
213
603873
2942
gdje je neurobiološki, i drugi nivo deskripcije
10:06
where it's mental, and that's a single event,
214
606839
2167
gdje je mentalni, a to je jedan događaj,
10:09
and that's how nature works. That's how it's possible
215
609030
2524
i tako priroda funkcionira. Tako je moguće
10:11
for consciousness to function causally.
216
611578
2569
da svijest uzročno utječe.
10:14
Okay, now with that in mind,
217
614171
2835
S tim na umu,
10:17
with going through these various features of consciousness,
218
617030
3043
kad smo prošli ova razna svojstva svijesti,
10:20
let's go back and answer some of those early objections.
219
620097
3148
vratimo se natrag i odgovorimo na neke od ranih prigovora.
10:23
Well, the first one I said was, consciousness doesn't exist,
220
623269
3585
Prvi je bio da svijest ne postoji,
10:26
it's an illusion. Well, I've already answered that.
221
626878
1810
da je iluzija. Već sam odgovorio na to.
10:28
I don't think we need to worry about that.
222
628712
2000
Ne mislim da oko toga trebamo
10:30
But the second one had an incredible influence,
223
630736
3332
brinuti. No sljedeće je imalo nevjerojatan utjecaj,
10:34
and may still be around, and that is,
224
634092
1820
i možda je još aktualno, a to je,
10:35
"Well, if consciousness exists, it's really something else.
225
635936
3167
"Ako svijest postoji, zapravo je nešto drugo.
10:39
It's really a digital computer program running in your brain
226
639127
3739
Zapravo je digitalni kompjuterski program u vašem mozgu
10:42
and that's what we need to do to create consciousness
227
642890
2524
i kako bi kreirali svijest
10:45
is get the right program.
228
645438
1429
trebamo pravi program.
10:46
Yeah, forget about the hardware. Any hardware will do
229
646891
2524
Zaboravite na hardver. Svaki hardver će
10:49
provided it's rich enough and stable enough to carry the program."
230
649439
3143
poslužiti ako je dovoljno bogat i stabilan da nosi program".
10:52
Now, we know that that's wrong.
231
652606
2534
Znamo da je to pogrešno.
10:55
I mean, anybody who's thought about computers at all
232
655164
2985
Mislim, svatko tko je uopće razmišljao o kompjuterima može
10:58
can see that that's wrong, because computation
233
658173
2440
vidjeti da je to pogrešno, zato što je komputacija
11:00
is defined as symbol manipulation,
234
660637
2391
definirana kao manipulacija simbolima, obično
11:03
usually thought of as zeros as ones, but any symbols will do.
235
663052
2905
jedinicama i nulama, ali bilo koji simboli će poslužiti.
11:05
You get an algorithm that you can program
236
665981
3098
Dobijete algoritam koji možete programirati
11:09
in a binary code, and that's the defining trait
237
669103
3083
u binarni kod, i to je definirajuća značajka
11:12
of the computer program.
238
672210
2027
kompjuterskog programa.
11:14
But we know that that's purely syntactical. That's symbolic.
239
674261
3859
No znamo da je to čisto sintaktički. To je simbolički.
11:18
We know that actual human consciousness has something more than that.
240
678144
3991
Znamo da stvarna ljudska svijest ima nešto više od toga.
11:22
It's got a content in addition to the syntax.
241
682159
3169
Uz sintaksu, ima i sadržaj.
11:25
It's got a semantics.
242
685352
1473
Ima semantiku.
11:26
Now that argument, I made that argument 30 --
243
686849
2465
Ovaj argument, dao sam ovaj argument 30 -- o Bože,
11:29
oh my God, I don't want to think about it —
244
689338
1267
ne želim misliti o tom --
11:30
more than 30 years ago,
245
690629
1318
pred više od 30 godina, no
11:31
but there's a deeper argument implicit in what I've told you,
246
691971
2905
postoji dublji argument impliciran u onome
11:34
and I want to tell you that argument briefly, and that is,
247
694900
3019
što sam vam rekao, i želim vam ga ukratko reći, a to je,
11:37
consciousness creates an observer-independent reality.
248
697943
4126
svijest stvara realnost neovisnu od promatrača.
11:42
It creates a reality of money, property, government,
249
702093
3464
Stvara svijest novca, vlasništva, vlade,
11:45
marriage, CERN conferences,
250
705581
3948
braka, CERN konferencija,
11:49
cocktail parties and summer vacations,
251
709553
2595
koktel-zabava i ljetnih praznika,
11:52
and all of those are creations of consciousness.
252
712172
2725
i sve ovo su kreacije svijesti.
11:54
Their existence is observer-relative.
253
714921
2811
Njihovo postojanje je ovisno o promatraču.
11:57
It's only relative to conscious agents that a piece of paper
254
717756
3479
Samo u odnosu na svjesne djelatnike je komad papira
12:01
is money or that a bunch of buildings is a university.
255
721259
2823
novac ili skupina zgrada sveučilište.
12:04
Now, ask yourself about computation.
256
724106
3850
Zapitajte se o komputaciji.
12:07
Is that absolute, like force and mass and gravitational attraction?
257
727980
3645
Je li toliko apsolutna, poput sile i mase i gravitacijskog privlačenja?
12:11
Or is it observer-relative?
258
731649
2108
Ili je relativna u odnosu na promatrača?
12:13
Well, some computations are intrinsic.
259
733781
3503
Neke su komputacije intrinzične.
12:17
I add two plus two to get four.
260
737308
1887
Zbrojim dva i dva kako bih dobio četiri.
12:19
That's going on no matter what anybody thinks.
261
739219
2547
To se događa bez obzira što netko mislio.
12:21
But when I haul out my pocket calculator
262
741790
2465
No kada izvadim svoj džepni kalkulator
12:24
and do the calculation, the only intrinsic phenomenon
263
744279
3758
i izračunam, jedini intrinzični fenomen
12:28
is the electronic circuit and its behavior.
264
748061
3151
je elektronički sklop i njegovo ponašanje.
12:31
That's the only absolute phenomenon.
265
751236
1740
To je jedini apsolutni fenomen.
12:33
All the rest is interpreted by us.
266
753000
2404
Sve ostalo je naša interpretacija.
12:35
Computation only exists relative to consciousness.
267
755428
3817
Komputacija postoji samo relativno u odnosu na svijest.
12:39
Either a conscious agent is carrying out the computation,
268
759269
2751
Ili svjesni djelatnik izvodi komputaciju,
12:42
or he's got a piece of machinery that admits of a computational interpretation.
269
762044
3762
ili ima stroj koji omogućava komputacijsku interpretaciju.
12:45
Now that doesn't mean computation is arbitrary.
270
765830
2901
To ne znači da je komputacija arbitrarna.
12:48
I spent a lot of money on this hardware.
271
768755
2424
Potrošio sam puno novca na ovaj hardver.
12:51
But we have this persistent confusion
272
771203
2122
No ipak postoji ova uporna konfuzija
12:53
between objectivity and subjectivity as features of reality
273
773349
4697
između objektivnosti i subjektivnosti kao svojstva realnosti
12:58
and objectivity and subjectivity as features of claims.
274
778070
3904
i objektivnosti i subjektivnosti kao svojstva tvrdnji.
13:01
And the bottom line of this part of my talk is this:
275
781998
3142
Zaključak ovog dijela mog govora jest:
13:05
You can have a completely objective science,
276
785164
3627
Možete imati posve objektivnu znanost,
13:08
a science where you make objectively true claims,
277
788815
2888
znanost gdje dajete objektivno istinite tvrdnje,
13:11
about a domain whose existence is subjective,
278
791727
3406
o domeni čije je postojanje subjektivno,
13:15
whose existence is in the human brain
279
795157
3211
čije postojanje je u ljudskom mozgu
13:18
consisting of subjective states of sentience
280
798392
2115
i sastoji se od subjektivnih stanja osjeta
13:20
or feeling or awareness.
281
800531
1661
ili osjećanja ili svjesnosti.
13:22
So the objection that you can't have an objective science of consciousness
282
802216
4313
Tako da je prigovor da ne možete imati objektivnu znanost svijesti
13:26
because it's subjective and science is objective, that's a pun.
283
806553
4184
zato što je subjektivna, a znanost je objektivna, dosjetka.
13:30
That's a bad pun on objectivity and subjectivity.
284
810761
2685
To je loša dosjetka o objektivnosti i subjektivnosti.
13:33
You can make objective claims
285
813470
2300
Možete izreći objektivne tvrdnje
13:35
about a domain that is subjective in its mode of existence,
286
815794
4018
o domeni koja je subjektivna po svom načinu postojanja,
13:39
and indeed that's what neurologists do.
287
819836
1549
i to je ono što neurolozi rade.
13:41
I mean, you have patients that actually suffer pains,
288
821409
2524
Imate pacijente koji zbilja pate od bolova,
13:43
and you try to get an objective science of that.
289
823957
2607
i pokušavate imati objektivnu znanost o tome.
13:46
Okay, I promised to refute all these guys,
290
826588
2048
U redu, obećao sam opovrgnuti sve te ljude,
13:48
and I don't have an awful lot of time left,
291
828660
1551
a nije mi preostalo puno vremena,
13:50
but let me refute a couple more of them.
292
830235
1905
no dozvolite da opovrgnem još nekoliko.
13:52
I said that behaviorism ought to be
293
832164
2190
Rekao sam da je biheviorizam zacijelo
13:54
one of the great embarrassments of our intellectual culture,
294
834378
3265
jedna od najvećih sramota naše intelektualne kulture,
13:57
because it's refuted the moment you think about it.
295
837667
2869
zato što je opovrgnut onog trenutka kad pomislite na njega.
14:00
Your mental states are identical with your behavior?
296
840560
2833
Vaša mentalna stanja su identična s vašim ponašanjem?
14:03
Well, think about the distinction between feeling a pain
297
843417
3127
Pa, razmislite o razlici između osjećanja boli
14:06
and engaging in pain behavior.
298
846568
1679
i ponašanja karakterističnog za bol.
14:08
I won't demonstrate pain behavior, but I can tell you
299
848271
1964
Neću demonstrirati to ponašanje, no mogu
14:10
I'm not having any pains right now.
300
850259
1815
vam reći da nemam nikakvih bolova sada.
14:12
So it's an obvious mistake. Why did they make the mistake?
301
852098
4096
Tako da je to očita pogreška? Zašto su tako pogriješili?
14:16
The mistake was — and you can go back and read
302
856218
2191
Pogreška je bila -- i možete pročitati
14:18
the literature on this, you can see this over and over —
303
858433
2667
literaturu o ovome, možete ovo primjetiti --
oni misle da ako prihvatite ireducibilno postojanje
14:21
they think if you accept the irreducible existence
304
861124
3559
14:24
of consciousness, you're giving up on science.
305
864707
2771
svijesti, odustajete od znanosti.
14:27
You're giving up on 300 years of human progress
306
867502
3047
Odustajete od 300 godina ljudskog napretka
14:30
and human hope and all the rest of it.
307
870573
1810
i ljudske nade i ostaloga.
14:32
And the message I want to leave you with is,
308
872407
2791
A poruka s kojom vas želim ostaviti jest,
14:35
consciousness has to become accepted
309
875222
2419
svijest treba postati prihvaćena
14:37
as a genuine biological phenomenon,
310
877665
2464
kao istinski biološki fenomen,
14:40
as much subject to scientific analysis
311
880153
2443
onoliko subjektivan znanstvenoj analizi
14:42
as any other phenomenon in biology,
312
882620
1936
koliko god i drugi fenomen u biologiji,
14:44
or, for that matter, the rest of science.
313
884580
2130
ili, dapače, u znanosti općenito.
14:46
Thank you very much.
314
886734
1358
Puno vam hvala.
14:48
