00:12
I'm going to talk about consciousness.
0
12464
2593
Govoriću o svesti.
00:15
Why consciousness?
1
15081
1456
Zašto o svesti?
00:16
Well, it's a curiously neglected subject,
2
16561
2802
Zato što je čudno zanemarena
00:19
both in our scientific and our philosophical culture.
3
19387
3540
i u našoj naučnoj i u filozofskoj kulturi.
00:22
Now why is that curious?
4
22951
1248
Zašto je to čudno?
00:24
Well, it is the most important aspect of our lives
5
24223
3486
Zato što je to najvažniji aspekt naših života
00:27
for a very simple, logical reason,
6
27733
1934
iz vrlo jednostavnog, logičnog razloga,
00:29
namely, it's a necessary condition on anything
7
29691
2373
naime, neophodan uslov
00:32
being important in our lives that we're conscious.
8
32088
2453
da nešto bude značajno u našim životima, je da smo svesni.
00:34
You care about science, philosophy, music, art, whatever --
9
34565
3135
Stalo vam je do nauke, filozofije, muzike, umetnosti, čega god -
00:37
it's no good if you're a zombie or in a coma, right?
10
37724
3454
a ne vredi ako ste zombi ili u komi, zar ne?
00:41
So consciousness is number one.
11
41202
2320
Tako je svest na prvom mestu.
00:43
The second reason is that when people do
12
43546
2444
Drugi razlog je da i kada se ljudi
00:46
get interested in it, as I think they should,
13
46014
2292
zaista zaineresuju za nju, kako mislim da bi trebalo,
00:48
they tend to say the most appalling things.
14
48330
2827
obično govore najgore stvari.
00:51
And then, even when they're not saying appalling things
15
51181
2620
Čak i kada ne govore najgore stvari
00:53
and they're really trying to do serious research,
16
53825
2334
i kada zaista ozbiljno istražuju pa, tada je to sporo.
Progres je 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 sam se prvi put zainteresovao za svest, pomislio sam
01:02
it's a straightforward problem in biology.
19
62464
2182
da je to jasan problem biologije.
01:04
Let's get these brain stabbers to get busy and figure out
20
64670
2473
Hajde da uposlimo te napadače mozga da odgonetnu
01:07
how it works in the brain.
21
67167
860
kako to funkcioniše u mozgu.
01:08
So I went over to UCSF and I talked to all
22
68051
2000
Tako sam otišao na kalifornijski fakultet i razgovarao sa svim
01:10
the heavy-duty neurobiologists there,
23
70075
1769
01:11
and they showed some impatience,
24
71868
1552
velikim neurobiolozima tamo
i bili su pomalo nestrpljivi
01:13
as scientists often do when you ask them embarrassing questions.
25
73444
3359
kao što često znaju biti naučnici kada im postavljaš nezgodna pitanja.
01:16
But the thing that struck me is, one guy said in exasperation,
26
76827
3734
Šokiralo me je šta je jedan od njih, čuven neurobiolog,
01:20
a very famous neurobiologist, he said, "Look,
27
80585
2143
u rastrojstvu rekao: "Gledaj,
01:22
in my discipline it's okay to be interested in consciousness,
28
82752
3399
u mojoj struci je u redu biti zainteresovan za svest
01:26
but get tenure first. Get tenure first."
29
86175
3543
ali prvo postani redovan profesor. To je prvo."
01:29
Now I've been working on this for a long time.
30
89742
2694
Pa sad, na ovome radim veoma dugo.
01:32
I think now you might actually get tenure
31
92460
1954
Mislim da sada možete postati redovan profesor
01:34
by working on consciousness.
32
94438
1334
radeći na svesti.
01:35
If so, that's a real step forward.
33
95796
2522
Ako je tako, to je pravi korak napred.
01:38
Okay, now why then is this curious reluctance
34
98342
2881
Dobro, a otkuda onda to čudno opiranje
01:41
and curious hostility to consciousness?
35
101247
1874
i čudna odbojnost prema svesti?
01:43
Well, I think it's a combination of two features
36
103145
2706
Pa, mislim da je to kombinacija dve osobine
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 da misle da oponiraju jedne drugima,
01:50
but in fact they share a common set of assumptions.
39
110306
3599
a u stvari dele isti niz pretpostavki.
01:53
One feature is the tradition of religious dualism:
40
113929
3938
Jedna osobina je tradicija religioznog dualizma:
01:57
Consciousness is not a part of the physical world.
41
117891
3301
svest nije deo fizičkog sveta.
02:01
It's a part of the spiritual world.
42
121216
1903
Ona je deo duhovnog sveta.
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 deo fizičkog sveta.
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 još jedna tradicija koja sebe smatra suprotnom toj
02:13
but accepts the worst assumption.
47
133111
2080
ali prihvata najgoru pretpostavku.
02:15
That tradition thinks that we are heavy-duty scientific materialists:
48
135215
4054
Ta tradicija misli da smo mi veliki naučni materijalisti:
02:19
Consciousness is not a part of the physical world.
49
139293
3441
svest nije deo fizičkog sveta.
02:22
Either it doesn't exist at all, or it's something else,
50
142758
2622
Ili uopšte ne postoji ili je nešto drugo,
02:25
a computer program or some damn fool thing,
51
145404
2626
računarski program ili neka budalaština,
02:28
but in any case it's not part of science.
52
148054
3171
ali u svakom slučaju nije deo nauke.
02:31
And I used to get in an argument that really gave me a stomachache.
53
151249
2184
I obično sam dobijao argument od kojeg me je boleo stomak.
02:33
Here's how it went.
54
153457
1595
Evo kako je glasio.
02:35
Science is objective, consciousness is subjective,
55
155076
4008
Nauka je objektivna, svest je subjektivna,
02:39
therefore there cannot be a science of consciousness.
56
159108
3303
pa zato ne može postojati nauka o svesti.
02:42
Okay, so these twin traditions are paralyzing us.
57
162435
6480
Zato nas te tradicije bliznakinje parališu.
02:48
It's very hard to get out of these twin traditions.
58
168939
2844
Veoma je teško izaći iz tih bliskih tradicija.
02:51
And I have only one real message in this lecture,
59
171807
2994
Imam samo jednu pravu poruku u ovom predavanju,
02:54
and that is, consciousness is a biological phenomenon
60
174825
3360
a to je da je svest biološki fenomen
02:58
like photosynthesis, digestion, mitosis --
61
178209
2865
kao što su fotosinteza, varenje, mitoze -
03:01
you know all the biological phenomena -- and once you accept that,
62
181098
4311
znate sve biološke fenomene - i jednom kada to prihvatite,
03:05
most, though not all, of the hard problems
63
185433
2615
većina iako ne i svi najveći problemi
03:08
about consciousness simply evaporate.
64
188072
2251
o svesti jednostavno nestanu.
03:10
And I'm going to go through some of them.
65
190347
2029
Pomenuću neke od njih.
03:12
Okay, now I promised you to tell you some
66
192400
2309
Obećao sam da ću vam reći neke
03:14
of the outrageous things said about consciousness.
67
194733
2715
od nečuvenih stvari izrečenih o svesti.
03:17
One: Consciousness does not exist.
68
197472
3576
Prva: svest ne postoji.
03:21
It's an illusion, like sunsets.
69
201072
2206
To je iluzija, kao zalasci sunca.
03:23
Science has shown sunsets and rainbows are illusions.
70
203302
5041
Nauka je dokazala da su zalasci sunca i duge iluzije.
03:28
So consciousness is an illusion.
71
208367
1899
Tako je svest iluzija.
03:30
Two: Well, maybe it exists, but it's really something else.
72
210290
3231
Druga: možda postoji, ali je stvarno nešto drugo.
03:33
It's a computer program running in the brain.
73
213545
3757
To je kompjuterski program koji se odvija u mozgu.
03:37
Three: No, the only thing that exists is really behavior.
74
217326
3790
Treće: ne, jedino što stvarno postoji je ponašanje.
03:41
It's embarrassing how influential behaviorism was,
75
221140
3584
Posramljujuće je koliko je bihejviorizam bio uticajan
03:44
but I'll get back to that.
76
224748
1331
ali na to ću se vratiti.
03:46
And four: Maybe consciousness exists,
77
226103
2710
I četvrto: možda svest postoji
03:48
but it can't make any difference to the world.
78
228837
2191
ali to i tako ne menja ništa na svetu.
Kako bi duhovnost mogla da pokrene bilo šta?
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 neko to kaže, pomislim:
03:55
you want to see spirituality move something?
81
235987
2266
"Želite li da vidite kako duhovnost nešto pokreće?
Gledajte. Svesno sam odlučio da podignem 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 ta prokleta stvar se podiže." (Smeh)
04:03
Furthermore, notice this:
84
243738
3747
Osim toga, оbratite pažnju na ovo:
04:07
We do not say, "Well, it's a bit like the weather in Geneva.
85
247509
3971
ne kažemo: "To je kao vreme u Ženevi.
04:11
Some days it goes up and some days it doesn't go up."
86
251504
2624
Nekim danima se diže, a nekim ne."
04:14
No. It goes up whenever I damn well want it to.
87
254152
2631
Ne. Podiže se kad god ja to prokleto zaželim.
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.
Još vam nisam 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 raditi bez definicije.
04:24
People always say consciousness is very hard to define.
91
264974
2962
Ljudi uvek kažu kako je svest vrlo teško definisati.
04:27
I think it's rather easy to define
92
267960
1859
Mislim da je prilično lako definisati
04:29
if you're not trying to give a scientific definition.
93
269843
2185
ako ne pokušavate da date naučnu definiciju.
04:32
We're not ready for a scientific definition,
94
272052
2256
Nismo spremni za naučnu definiciju,
04:34
but here's a common-sense definition.
95
274332
1762
ali evo vam definicije zdravog razuma.
04:36
Consciousness consists of all those states of feeling
96
276118
2778
Svest se sastoji od svih stanja osećanja
04:38
or sentience or awareness.
97
278920
2044
ili oseta ili budnosti.
04:40
It begins in the morning when you wake up from a dreamless sleep,
98
280988
3534
Počinje ujutru kada se probudite iz sna bez snova,
04:44
and it goes on all day until you fall asleep
99
284546
2445
i odvija se tokom celog dana sve dok ne zaspite,
04:47
or die or otherwise become unconscious.
100
287015
3174
ne umrete ili na drugi način ne ostanete bez svesti.
04:50
Dreams are a form of consciousness on this definition.
101
290213
3096
Snovi su deo svesti tako definisane.
04:53
Now, that's the common-sense definition. That's our target.
102
293333
2878
To je sad definicija zdravog razuma. 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 svesti.
04:59
But they think, "Well, if that's it, that's an awful problem.
104
299736
3460
Ali oni misle: "Ako je tako, to je strašan problem.
05:03
How can such a thing exist as part of the real world?"
105
303220
3934
Kako tako nešto postoji kao deo stvarnog sveta?"
05:07
And this, if you've ever had a philosophy course,
106
307178
2334
Ako ste ikad učili filozofiju,
05:09
this is known as the famous mind-body problem.
107
309536
2727
ovo je poznato kao problem uma i tela.
05:12
I think that has a simple solution too. I'm going to give it to you.
108
312287
3239
Mislim da i to ima jednostavno rešenje. Izneću vam ga.
05:15
And here it is: All of our conscious states, without exception,
109
315550
3978
Evo ga: sva naša svesna stanja, bez izuzetka
05:19
are caused by lower-level neurobiological processes in the brain,
110
319552
5501
su izazvana nižim neurobiološkim procesima u mozgu
05:25
and they are realized in the brain
111
325077
2157
i ostvaruju se u mozgu
05:27
as higher-level or system features.
112
327258
2310
kao višem nivou ili svojstvima sistema.
05:29
It's about as mysterious as the liquidity of water.
113
329592
3132
To je mistično skoro kao i tečno stanje vode.
05:32
Right? The liquidity is not an extra juice squirted out
114
332748
3451
Je l' tako? Tečnost nije neki poseban sok
05:36
by the H2O molecules.
115
336223
1666
koji molekuli H2O cede.
05:37
It's a condition that the system is in.
116
337913
2854
To je stanje u kojem je sistem.
05:40
And just as the jar full of water can go from liquid to solid
117
340791
5138
Kao što bokal vode može preći iz tečnog u čvrsto stanje
05:45
depending on the behavior of the molecules,
118
345953
2048
u zavisnosti od ponašanja molekula,
tako i vaš mozak može preći iz stanja svesti
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
u stanje bez svesti
05:52
depending on the behavior of the molecules.
121
352542
2962
u zavisnosti od ponašanja molekula.
05:55
The famous mind-body problem is that simple.
122
355528
4361
Poznati problem uma i tela je jednostavan.
05:59
All right? But now we get into some harder questions.
123
359913
3153
Je l' da? Ali sada stižemo do težih pitanja.
06:03
Let's specify the exact features of consciousness,
124
363090
3420
Navedimo tačne karakteristike svesti,
06:06
so that we can then answer those four objections
125
366534
2448
pa da možemo odgovoriti na ona četiri prigovora
06:09
that I made to it.
126
369006
1263
koje sam naveo.
06:10
Well, the first feature is, it's real and irreducible.
127
370293
4243
Prva karakteristika je da je stvarna i neizbežna.
06:14
You can't get rid of it.
128
374560
2030
Ne možete da je se oslobodite.
06:16
You see, the distinction between reality and illusion
129
376614
4147
Vidite, razlika između stvarnosti i iluzije
06:20
is the distinction between how things
130
380785
2645
je u tome kako nam se stvari
06:23
consciously seem to us and how they really are.
131
383454
3850
svesno čine i kakve su one u stvarnosti.
06:27
It consciously seems like there's --
132
387328
1852
Svesno izgleda kao da je -
06:29
I like the French "arc-en-ciel" —
133
389204
1644
sviđa mi se francuski izraz za dugu "arc-en-ciel"-
06:30
it seems like there's an arch in the sky,
134
390872
2174
čini se kao da je luk na nebu,
06:33
or it seems like the sun is setting over the mountains.
135
393070
3756
ili izgleda kao da sunce zalazi iza planina.
06:36
It consciously seems to us, but that's not really happening.
136
396850
3073
Svesno nam se čini, ali to se u stvari ne dešava.
06:39
But for that distinction between
137
399947
1903
Ali s tom razlikom
06:41
how things consciously seem and how they really are,
138
401874
2477
kako se stvari svesno čine i kakve stvarno jesu,
06:44
you can't make that distinction for the very existence of consciousness,
139
404375
4031
ne možete dati razliku u vezi sa postojanjem same svesti,
06:48
because where the very existence of consciousness is concerned,
140
408430
3827
jer kada je postojanje svesti u pitanju
06:52
if it consciously seems to you that you are conscious,
141
412281
2956
ako vam se svesno čini da ste svesni,
06:55
you are conscious.
142
415261
1861
tada jeste svesni.
06:57
I mean, if a bunch of experts come to me and say,
143
417146
3330
Mislim, ako mi gomila stručnjaka kaže:
07:00
"We are heavy-duty neurobiologists and we've done a study
144
420500
2667
"Mi smo veliki neurobiolozi i napravili smo studiju
o vama, Serl, i ubeđeni smo da niste svesni
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
već da ste vrlo pametno konstruisan robot",
ja ne pomislim: "Možda su ovi ljudi u pravu, razumete?"
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 pomislim to ni za sekundu,
07:13
Descartes may have made a lot of mistakes, but he was right about this.
149
433845
2886
jer Dekart je možda mnogo grešio, ali je bio u pravu o tome.
07:16
You cannot doubt the existence of your own consciousness.
150
436755
2931
Ne možete sumnjati u postojanje sopstvene svesti.
07:19
Okay, that's the first feature of consciousness.
151
439710
2286
Dobro, to je prva karakteristika svesti.
Ona je realna i neizbežna.
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 da je se oslobodite prikazujući je iluzijom
07:27
in a way that you can with other standard illusions.
154
447055
3205
na način na koji to činite sa drugim iluzijama.
07:30
Okay, the second feature is this one
155
450284
2508
Dobro, druga karakteristika nam je
07:32
that has been such a source of trouble to us,
156
452816
2441
pravila tolike probleme,
07:35
and that is, all of our conscious states
157
455281
2158
a to je da sva naša svesna stanja
07:37
have this qualitative character to them.
158
457463
2940
imaju svoj kvalitativni karakter.
07:40
There's something that it feels like to drink beer
159
460427
2381
Postoji nešto što se oseća kao da pijete pivo
07:42
which is not what it feels like to do your income tax
160
462832
2921
što nije isti osećaj kao pri plaćanju poreza
07:45
or listen to music, and this qualitative feel
161
465777
3044
ili pri slušanju muzike i taj kvalitativni osećaj
07:48
automatically generates a third feature,
162
468845
2537
automatski proizvodi treću karakteristiku
07:51
namely, conscious states are by definition subjective
163
471406
3770
naime, svesna stanja su po definiciji subjektivna
07:55
in the sense that they only exist as experienced
164
475200
2931
u smislu da postoje jedino kroz iskustvo
07:58
by some human or animal subject,
165
478155
2171
koje je doživeo neki čovek ili životinja,
08:00
some self that experiences them.
166
480350
1849
neko biće koje ih je doživelo.
08:02
Maybe we'll be able to build a conscious machine.
167
482223
2359
Možda ćemo moći da napravimo svesnu mašinu.
08:04
Since we don't know how our brains do it,
168
484606
2129
S obzirom da ne znamo kako naš mozak to radi,
08:06
we're not in a position, so far, to build a conscious machine.
169
486759
4111
nismo još u poziciji da napravimo svesnu mašinu.
08:10
Okay. Another feature of consciousness
170
490894
2751
Dobro, sledeća karakteristika svesti
08:13
is that it comes in unified conscious fields.
171
493669
4127
jeste njeno pojavljivanje u objedinjenim svesnim poljima.
08:17
So I don't just have the sight of the people in front of me
172
497820
2332
Tako ja nemam samo uvid u ljude ispred mene
08:20
and the sound of my voice and the weight of my shoes
173
500176
2690
i u zvuk svog glasa i u težinu mojih cipela
08:22
against the floor, but they occur to me
174
502890
2151
u odnosu na pod, već mi se to pojavljuje
08:25
as part of one single great conscious field
175
505065
3458
kao deo jedinstvenog velikog svesnog polja
08:28
that stretches forward and backward.
176
508547
1992
koje se proteže napred i nazad.
08:30
That is the key to understanding
177
510563
1745
To je ključ razumevanja
08:32
the enormous power of consciousness.
178
512332
2415
ogromne snage svesnog stanja.
08:34
And we have not been able to do that in a robot.
179
514771
2920
I to nismo u mogućnosti da stvorimo u robotu.
08:37
The disappointment of robotics derives from the fact
180
517715
2477
Razočarenje u robote proizlazi iz činjenice
08:40
that we don't know how to make a conscious robot,
181
520216
2334
da ne znamo kako da napravimo svesnog robota,
08:42
so we don't have a machine that can do this kind of thing.
182
522574
3025
pa nemamo mašinu koja bi to mogla da uradi.
08:45
Okay, the next feature of consciousness,
183
525623
2484
Sledeća osobina svesti
08:48
after this marvelous unified conscious field,
184
528131
3091
posle ovog veličanstvenog objedinjenog polja svesti,
08:51
is that it functions causally in our behavior.
185
531246
2769
jeste njena uzročna funkcija u našem ponašanju.
08:54
I gave you a scientific demonstration by raising my hand,
186
534039
3179
Dao sam vam naučnu demonstraciju dizanjem ruke,
08:57
but how is that possible?
187
537242
1726
ali kako je to moguće?
08:58
How can it be that this thought in my brain
188
538992
3740
Kako je moguće da ta pomisao u mom mozgu
09:02
can move material objects?
189
542756
2176
može da pomera materijalne objekte?
09:04
Well, I'll tell you the answer.
190
544956
1477
Odgovoriću vam.
09:06
I mean, we don't know the detailed answer,
191
546457
2000
Ne znamo detaljno da odgovorimo
09:08
but we know the basic part of the answer, and that is,
192
548481
2678
ali znamo osnovni deo odgovora, a to je
09:11
there is a sequence of neuron firings,
193
551183
2269
postoji niz neuronskih nadražaja
09:13
and they terminate where the acetylcholine
194
553476
3063
koji završavaju tamo gde se acetilholin
09:16
is secreted at the axon end-plates of the motor neurons.
195
556563
2797
luči na neuromotornoj ploči.
09:19
Sorry to use philosophical terminology here,
196
559384
2096
Oprostite što se koristim filozofskom terminologijom ovde,
09:21
but when it's secreted at the axon end-plates of the motor neurons,
197
561504
3947
ali kada se izlučuje na neuromotornoj ploči,
09:25
a whole lot of wonderful things happen in the ion channels
198
565475
2762
mnogo lepih stvari se dešava u jonskim kanalima
09:28
and the damned arm goes up.
199
568261
1882
i prokleta ruka se diže.
09:30
Now, think of what I told you.
200
570167
2100
Razmislite o tome što sam rekao.
09:32
One and the same event,
201
572291
1718
Jedan isti događaj,
09:34
my conscious decision to raise my arm
202
574033
3011
moja svesna odluka da podignem ruku
09:37
has a level of description where it has all of these
203
577068
2771
ima nivo opisa pri kojem ima sve ove
09:39
touchy-feely spiritual qualities.
204
579863
2122
osećajne duhovne kvalitete.
09:42
It's a thought in my brain, but at the same time,
205
582009
2377
To je misao u mom mozgu, ali u isto vreme
09:44
it's busy secreting acetylcholine
206
584410
1962
je on zauzet izlučivanjem acetilholina
09:46
and doing all sorts of other things
207
586396
1667
i radi razne druge stvari
probijajući se iz 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
dole preko nervnih vlakana u ruci.
09:53
Now, what that tells us is that our traditional vocabularies
210
593416
3792
To nam govori da je naš tradicionalni rečnik
09:57
for discussing these issues are totally obsolete.
211
597232
3360
pri raspravi o tim temama sasvim zastareo.
10:00
One and the same event has a level of description
212
600616
3233
Jedan isti događaj ima nivo opisa
10:03
where it's neurobiological, and another level of description
213
603873
2942
koji je neurobiološki i drugi nivo opisa
10:06
where it's mental, and that's a single event,
214
606839
2167
koji je mentalni, a radi se o istom događaju
10:09
and that's how nature works. That's how it's possible
215
609030
2524
i tako priroda funkcioniše.
Tako je moguće da svest funkcioniše uzročno.
10:11
for consciousness to function causally.
216
611578
2569
10:14
Okay, now with that in mind,
217
614171
2835
Imajući to na umu
10:17
with going through these various features of consciousness,
218
617030
3043
i prolazeći kroz sve različite karakteristike svesti,
10:20
let's go back and answer some of those early objections.
219
620097
3148
vratimo se da bismo odgovorili na neke od ranijih prigovora.
10:23
Well, the first one I said was, consciousness doesn't exist,
220
623269
3585
Pa, prvo sam rekao da svest ne postoji, da je to iluzija.
10:26
it's an illusion. Well, I've already answered that.
221
626878
1810
Na to sam već odgovorio.
10:28
I don't think we need to worry about that.
222
628712
2000
Mislim da to ne bi trebalo da nas zabrinjava.
10:30
But the second one had an incredible influence,
223
630736
3332
Ali drugi prigovor ima neverovatan uticaj,
10:34
and may still be around, and that is,
224
634092
1820
i možda još postoji, a to je:
10:35
"Well, if consciousness exists, it's really something else.
225
635936
3167
"Ako svest postoji, to je nešto drugo.
10:39
It's really a digital computer program running in your brain
226
639127
3739
To je zaista digitalni kompjuterski program koji se odvija u vašem mozgu
10:42
and that's what we need to do to create consciousness
227
642890
2524
i da bismo kreirali svest
10:45
is get the right program.
228
645438
1429
treba da imamo pravi program.
10:46
Yeah, forget about the hardware. Any hardware will do
229
646891
2524
I da, zaboravite na hardver.
Bilo koji hardver će poslužiti
10:49
provided it's rich enough and stable enough to carry the program."
230
649439
3143
pod uslovom da je dovoljno bogat i stabilan da izvodi 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
Svako ko je razmišljao o kompjuterima uopšte
10:58
can see that that's wrong, because computation
233
658173
2440
može videti da je pogrešno, jer komputacija
11:00
is defined as symbol manipulation,
234
660637
2391
je definisana kao manipulacija simbolima
11:03
usually thought of as zeros as ones, but any symbols will do.
235
663052
2905
o kojoj se obično razmišlja kao o nulama i jedinicama, ali može svaki simbol.
11:05
You get an algorithm that you can program
236
665981
3098
Dobijate algoritam koji možete programirati
11:09
in a binary code, and that's the defining trait
237
669103
3083
u binarnom kodu, a to je definišuća osobina
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
Ali znamo da je to čisto sintaktičko. To je simbolično.
11:18
We know that actual human consciousness has something more than that.
240
678144
3991
Znamo da prava ljudska svest ima nešto više od toga.
11:22
It's got a content in addition to the syntax.
241
682159
3169
Ima sadržaj osim sintakse.
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
To sam tvrdio 30 -
11:29
oh my God, I don't want to think about it —
244
689338
1267
o bože, ne želim da razmišljam o tome -
11:30
more than 30 years ago,
245
690629
1318
11:31
but there's a deeper argument implicit in what I've told you,
246
691971
2905
pre više od 30 godina,
ali postoji dublji argument u tome što sam vam rekao,
11:34
and I want to tell you that argument briefly, and that is,
247
694900
3019
i ukratko ću vam ga reći,
11:37
consciousness creates an observer-independent reality.
248
697943
4126
to je da svest stvara od posmatrača nezavisnu stvarnost.
11:42
It creates a reality of money, property, government,
249
702093
3464
Ona stvara stvarnost 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 prijema i letnjih odmora
11:52
and all of those are creations of consciousness.
252
712172
2725
i to su sve tvorevine svesti.
11:54
Their existence is observer-relative.
253
714921
2811
Njihovo postojanje je zavisno od posmatrača.
11:57
It's only relative to conscious agents that a piece of paper
254
717756
3479
Samo od činilaca svesti zavisi da je parče papira
12:01
is money or that a bunch of buildings is a university.
255
721259
2823
novac ili gomila zgrada univerzitet.
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
Da li je to apsolutno, kao što je sila i masa i gravitacijska privlačnost?
12:11
Or is it observer-relative?
258
731649
2108
Ili da li je relativno zavisno od posmatrača?
12:13
Well, some computations are intrinsic.
259
733781
3503
Pa, neke komputacije su unutarnje.
12:17
I add two plus two to get four.
260
737308
1887
Saberem 2 plus 2 da dobijem 4.
12:19
That's going on no matter what anybody thinks.
261
739219
2547
To se dešava bez obzira na to šta ko misli.
12:21
But when I haul out my pocket calculator
262
741790
2465
Ali kada izvučem svoj džepni kalkulator
12:24
and do the calculation, the only intrinsic phenomenon
263
744279
3758
koji obavi kalkulaciju, jedini unutarnji fenomen
12:28
is the electronic circuit and its behavior.
264
748061
3151
je električno kolo 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 sami tumačimo.
12:35
Computation only exists relative to consciousness.
267
755428
3817
Komputacija postoji samo u odnosu prema svesti.
12:39
Either a conscious agent is carrying out the computation,
268
759269
2751
Ili činilac svesti izvodi komputaciju
12:42
or he's got a piece of machinery that admits of a computational interpretation.
269
762044
3762
ili ima deo mašinerije koja dopušta matematičku interpretaciju.
12:45
Now that doesn't mean computation is arbitrary.
270
765830
2901
To ne znači da je komputacija proizvoljna.
12:48
I spent a lot of money on this hardware.
271
768755
2424
Potrošio sam dosta novca na taj hardver.
12:51
But we have this persistent confusion
272
771203
2122
Ali imamo ovu stalnu zabunu
12:53
between objectivity and subjectivity as features of reality
273
773349
4697
između objektivnosti i subjektivnosti kao svojstava stvarnosti
12:58
and objectivity and subjectivity as features of claims.
274
778070
3904
i objektivnosti i subjektivnosti kao svojstava tvrdnji.
13:01
And the bottom line of this part of my talk is this:
275
781998
3142
I suština ovog dela mog izlaganja je ovo:
13:05
You can have a completely objective science,
276
785164
3627
možete imati potpuno objektivnu nauku,
13:08
a science where you make objectively true claims,
277
788815
2888
nauku s objektivnim tvrdnjama,
13:11
about a domain whose existence is subjective,
278
791727
3406
o domenu 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
sastavljeno od subjektivnih stanja oseta
13:20
or feeling or awareness.
281
800531
1661
ili osećanja ili budnosti.
13:22
So the objection that you can't have an objective science of consciousness
282
802216
4313
Zato prigovor da ne možete imati objektivnu nauku o svesti
13:26
because it's subjective and science is objective, that's a pun.
283
806553
4184
jer je ona subjektivna, a nauka je objektivna, jeste igra reči.
13:30
That's a bad pun on objectivity and subjectivity.
284
810761
2685
To je loša igra reči o objektivnosti i subjektivnosti.
13:33
You can make objective claims
285
813470

Možete objektivno tvrditi
13:35
about a domain that is subjective in its mode of existence,
286
815794
4018
o domenu koji je po prirodi subjektivan
13:39
and indeed that's what neurologists do.
287
819836
1549
i to je ono što rade neurobiolozi.
13:41
I mean, you have patients that actually suffer pains,
288
821409
2524
Imate pacijente koji imaju bolove,
13:43
and you try to get an objective science of that.
289
823957
2607
i pokušavate da dobijete objektivnu nauku o tome.
13:46
Okay, I promised to refute all these guys,
290
826588
2048
Obećao sam da ću opovrgnuti tvrdnje tih ljudi,
13:48
and I don't have an awful lot of time left,
291
828660
1551
i nemam previše vremena
13:50
but let me refute a couple more of them.
292
830235
1905
ali dozvolite mi da opovrgnem još par.
13:52
I said that behaviorism ought to be
293
832164
2190
Rekao sam da bi bihejviorizam trebalo da bude
13:54
one of the great embarrassments of our intellectual culture,
294
834378
3265
jedna od velikih sramota naše intelektualne kulture,
13:57
because it's refuted the moment you think about it.
295
837667
2869
jer je odbačen u momentu čim o tome razmišljamo.
14:00
Your mental states are identical with your behavior?
296
840560
2833
Vaša mentalna stanja su identična sa vašim ponašanjem?
14:03
Well, think about the distinction between feeling a pain
297
843417
3127
Pa razmislite o razlici između osećaja bola
14:06
and engaging in pain behavior.
298
846568
1679
i angažovanja u bolnom ponašanju.
14:08
I won't demonstrate pain behavior, but I can tell you
299
848271
1964
Neću demonstrirati bolno ponašanje, ali mogu vam reći
14:10
I'm not having any pains right now.
300
850259
1815
da nemam nikakve bolove sada.
14:12
So it's an obvious mistake. Why did they make the mistake?
301
852098
4096
Dakle to je očigledna greška. Zašto su tako pogrešili?
14:16
The mistake was — and you can go back and read
302
856218
2191
Greška je u tome - i možete se vratiti i pročitati
14:18
the literature on this, you can see this over and over —
303
858433
2667
literaturu o tome, možete to videti svaki put iznova -
14:21
they think if you accept the irreducible existence
304
861124
3559
oni misle da ako prihvatite neizbežno postojanje
14:24
of consciousness, you're giving up on science.
305
864707
2771
svesti, odustajete od nauke.
14:27
You're giving up on 300 years of human progress
306
867502
3047
Odustajete od 300 godina ljudskog progresa
14:30
and human hope and all the rest of it.
307
870573
1810
i ljudske nade i svega ostalog.
14:32
And the message I want to leave you with is,
308
872407
2791
A poruka s kojom vas želim ostaviti
14:35
consciousness has to become accepted
309
875222
2419
je da svest mora postati prihvaćena
14:37
as a genuine biological phenomenon,
310
877665
2464
kao izvorni biološki fenomen
14:40
as much subject to scientific analysis
311
880153
2443
i utoliko predmet naučnih analiza
14:42
as any other phenomenon in biology,
312
882620
1936
kao i bilo koji drugi fenomen u biologiji
14:44
or, for that matter, the rest of science.
313
884580
2130
ili što se toga tiče, u ostatku nauke.
14:46
Thank you very much.
314
886734
1358
Hvala vam mnogo.
