Baš sada
00:14
you have a movie playing inside your head.
1
14515
3474
vam se odvija film u glavi.
00:17
It's an amazing multi-track movie.
2
17989
2527
To je neverovatan film na više kanala.
00:20
It has 3D vision and surround sound
3
20516
3324
Ima 3D vid i okružujući zvuk
00:23
for what you're seeing and hearing right now,
4
23840
2636
za ono što sada vidite i čujete,
00:26
but that's just the start of it.
5
26476
2319
ali to je samo početak.
00:28
Your movie has smell and taste and touch.
6
28795
5183
Vaš film ima miris i ukus i dodir.
00:33
It has a sense of your body,
7
33978
2552
Ima osećaj vašeg tela,
00:36
pain, hunger, orgasms.
8
36530
4319
bol, glad, orgazme.
00:40
It has emotions,
9
40849
2041
Ima emocije,
00:42
anger and happiness.
10
42890
3536
gnev i sreću.
00:46
It has memories, like scenes from your childhood
11
46426
3794
Ima sećanja, kao što su scene iz vašeg detinjstva
00:50
playing before you.
12
50220
2700
koje se odigravaju pred vama.
00:52
And it has this constant voiceover narrative
13
52920
4455
I ima taj stalni narativ
00:57
in your stream of conscious thinking.
14
57375
4376
u vašem toku svesnog razmišljanja.
01:01
At the heart of this movie is you
15
61751
5073
U srcu ovog filma ste vi
01:06
experiencing all this directly.
16
66824
4365
koji to direktno doživljavate.
01:11
This movie is your stream of consciousness,
17
71189
5692
Ovaj film je vaš tok svesti,
01:16
the subject of experience
18
76881
1307
predmet iskustva
01:18
of the mind and the world.
19
78188
5138
uma i sveta.
01:23
Consciousness is one of the fundamental facts
20
83326
2305
Svest je jedna od fundamentalnih činjenica
01:25
of human existence.
21
85631
2017
ljudskog postojanja.
01:27
Each of us is conscious.
22
87648
2932
Svako od nas je svestan.
01:30
We all have our own inner movie,
23
90580
2729
Svi mi imamo naš sopstveni unutrašnji film,
01:33
you and you and you.
24
93309
2731
vi i vi i vi.
01:36
There's nothing we know about more directly.
25
96040
3720
Ne postoji ništa o čemu znamo više direktno.
01:39
At least, I know about my consciousness directly.
26
99760
3472
Ili makar ja znam o svojoj svesti direktno.
01:43
I can't be certain that you guys are conscious.
27
103232
3998
Ne mogu da budem siguran da ste vi svesni.
01:47
Consciousness also is what makes life worth living.
28
107230
3428
Svest je takođe ono što čini život vrednim življenja.
01:50
If we weren't conscious, nothing in our lives
29
110658
3700
Kada ne bismo bili svesni, ništa u našim životima
01:54
would have meaning or value.
30
114358
3365
ne bi imalo smisao niti vrednost.
01:57
But at the same time, it's the most
31
117723
1166
Ali istovremeno, to je
01:58
mysterious phenomenon in the universe.
32
118889
4170
najmisterioznija pojava u univerzumu.
02:03
Why are we conscious?
33
123059
3373
Zašto smo svesni? Zašto imamo te unutrašnje filmove?
02:06
Why do we have these inner movies?
34
126432
1541
02:07
Why aren't we just robots
35
127973
2253
Zašto nismo samo roboti
02:10
who process all this input,
36
130226
2243
koji obrađuju sve te ulazne podatke,
02:12
produce all that output,
37
132469
2017
proizvode sve te izlazne podatke,
02:14
without experiencing the inner movie at all?
38
134486
3855
bez doživljavanja unutrašnjeg filma?
02:18
Right now, nobody knows the answers
39
138341
2509
U ovom trenutku, niko ne zna odgovore
02:20
to those questions.
40
140850
1746
na ta pitanja.
02:22
I'm going to suggest that to integrate consciousness
41
142596
3709
Ukazaću da,
za integrisanje svesti u nauku
02:26
into science, some radical ideas may be needed.
42
146305
4695
mogu biti potrebne neke radikalne ideje.
02:31
Some people say a science of consciousness
43
151000
2966
Neki ljudi kažu da je nauka svesti nemoguća.
02:33
is impossible.
44
153966
1952
02:35
Science, by its nature, is objective.
45
155918
3768
Nauka je, po svojoj prirodi, objektivna.
02:39
Consciousness, by its nature, is subjective.
46
159686
3425
Svest je, po svojoj prirodi, subjektivna.
02:43
So there can never be a science of consciousness.
47
163111
4449
Dakle, nikada ne može postojati nauka o svesti.
02:47
For much of the 20th century, that view held sway.
48
167560
3220
Većim delom XX veka, to gledište je bilo uzdrmano.
02:50
Psychologists studied behavior objectively,
49
170780
3818
Psiholozi su proučavali ponašanje objektivno,
02:54
neuroscientists studied the brain objectively,
50
174598
4062
neurolozi su proučavali mozak objektivno,
02:58
and nobody even mentioned consciousness.
51
178660
3550
a niko nije čak ni pomenuo svest.
03:02
Even 30 years ago, when TED got started,
52
182210
2756
Čak i pre 30 godina, kada je TED započeo,
03:04
there was very little scientific work
53
184966
2382
bilo je veoma malo naučnog rada
03:07
on consciousness.
54
187348
2552
o svesti.
03:09
Now, about 20 years ago,
55
189900
1705
Pre oko 20 godina,
03:11
all that began to change.
56
191605
2973
sve to je počelo da se menja.
03:14
Neuroscientists like Francis Crick
57
194578
2777
Neurolozi kao što je Frensis Krik
03:17
and physicists like Roger Penrose
58
197355
2756
i fizičari poput Rodžera Penroza
03:20
said now is the time for science
59
200111
2240
govorili su da je vreme da se nauka
03:22
to attack consciousness.
60
202351
2776
lati svesti.
03:25
And since then, there's been a real explosion,
61
205127
2320
I od tada, nastala je prava eksplozija,
03:27
a flowering of scientific work
62
207447
2337
procvat naučnog rada
03:29
on consciousness.
63
209784
1264
o svesti. I taj rad je bio izvanredan.
03:31
And this work has been wonderful. It's been great.
64
211048
2039
Bio je sjajan.
03:33
But it also has some fundamental
65
213087
2088
Ali takođe ima nekih fundamentalnih ograničenja za sada.
03:35
limitations so far.
66
215175
3825
03:39
The centerpiece
67
219000
1658
Središnje mesto
03:40
of the science of consciousness in recent years
68
220658
2820
u nauci o svesti poslednjih godina
03:43
has been the search for correlations,
69
223478
2495
je imala potraga za korelacijama,
03:45
correlations between certain areas of the brain
70
225973
3129
korelacijama između određenih oblasti mozga
03:49
and certain states of consciousness.
71
229102
4018
i određenih stanja svesti.
Videli smo neke od ovih radova kod Nensi Kanvišer i izvrsnog rada
03:53
We saw some of this kind of work
72
233120
1090
03:54
from Nancy Kanwisher and the wonderful work
73
234210
1760
03:55
she presented just a few minutes ago.
74
235970
3276
koji je predstavila pre samo nekoliko minuta.
03:59
Now we understand much better, for example,
75
239246
3563
Sada mnogo bolje razumemo, na primer,
04:02
the kinds of brain areas that go along with
76
242809
2317
vrste moždanih oblasti koje idu uz
04:05
the conscious experience of seeing faces
77
245126
3371
svesno iskustvo gledanja lica
04:08
or of feeling pain
78
248497
3120
ili osećanja bola
04:11
or of feeling happy.
79
251617
2489
ili osećanja sreće.
04:14
But this is still a science of correlations.
80
254106
2816
Ali ovo je još uvek nauka korelacija.
04:16
It's not a science of explanations.
81
256922
3356
To nije nauka objašnjenja.
04:20
We know that these brain areas
82
260278
2623
Znamo da ove oblasti mozga
04:22
go along with certain kinds of conscious experience,
83
262901
3924
idu uz određene vrste svesnog iskustva,
04:26
but we don't know why they do.
84
266825
3636
ali ne znamo zašto je to tako.
04:30
I like to put this by saying
85
270461
2325
Volim da to istaknem govoreći
04:32
that this kind of work from neuroscience
86
272786
3397
da ova vrsta rada neurologije
04:36
is answering some of the questions
87
276183
1746
odgovara na neka pitanja
04:37
we want answered about consciousness,
88
277929
1805
o svesti na koja želimo odgovore,
04:39
the questions about what certain brain areas do
89
279734
3773
pitanja o tome
šta određene moždane oblasti rade i sa čim koreliraju.
04:43
and what they correlate with.
90
283507
2109
04:45
But in a certain sense, those are the easy problems.
91
285616
3156
Ali na neki način, to su laki problemi.
04:48
No knock on the neuroscientists.
92
288772
2441
Prepad na neuronaučnike.
04:51
There are no truly easy problems with consciousness.
93
291213
2621
Nema zaista lakih problema sa svešću.
04:53
But it doesn't address the real mystery
94
293834
4591
Ali to se ne odnosi na stvarnu misteriju
04:58
at the core of this subject:
95
298425
1930
u srži ovog predmeta:
05:00
why is it that all that physical processing in a brain
96
300355
4220
zašto uopšte sva psihička procesovanja u mozgu
05:04
should be accompanied by consciousness at all?
97
304575
2925
treba da budu praćena svesnošću?
05:07
Why is there this inner subjective movie?
98
307500
3206
Zašto postoji ovaj unutrašnji subjektivni film?
05:10
Right now, we don't really have a bead on that.
99
310706
3254
U ovom trenutku, nemamo baš jasnu metu za to.
05:13
And you might say,
100
313960
2033
I možete reći: "Hajde samo
05:15
let's just give neuroscience a few years.
101
315993
3555
da damo neurologiji nekoliko godina.
05:19
It'll turn out to be another emergent phenomenon
102
319548
3780
Ispostaviće se da je to još jedna popularna pojava,
05:23
like traffic jams, like hurricanes,
103
323328
4882
kao što su zastoji u saobraćaju, uragani,
05:28
like life, and we'll figure it out.
104
328210
2621
kao što je život, i otkrićemo ga.
05:30
The classical cases of emergence
105
330831
2071
Klasični slučajevi pojavljivanja
05:32
are all cases of emergent behavior,
106
332902
3378
su svi slučajevi pojavnog ponašanja,
05:36
how a traffic jam behaves,
107
336280
2347
kako se saobraćajna gužva ponaša,
05:38
how a hurricane functions,
108
338627
1496
kako uragan funkcioniše,
05:40
how a living organism reproduces
109
340123
2193
kako se živi organizam razmožava i prilagođava i metaboliše,
05:42
and adapts and metabolizes,
110
342316
3589
05:45
all questions about objective functioning.
111
345905
2283
sve su to pitanja o objektivnom funkcionisanju.
05:48
You could apply that to the human brain
112
348188
2822
Možete to primeniti na ljudskom mozgu pri objašnjavanju
05:51
in explaining some of the behaviors
113
351010
1509
nekih ponašanja i funkcija
05:52
and the functions of the human brain
114
352519
2273
ljudskog mozga kao pojavnog fenomena:
05:54
as emergent phenomena:
115
354792
1159
05:55
how we walk, how we talk, how we play chess,
116
355951
4398
kako hodamo,
govorimo, igramo šah,
06:00
all these questions about behavior.
117
360349
1890
sva ta pitanja o ponašanju.
06:02
But when it comes to consciousness,
118
362239
2127
Ali kada se radi o svesti,
06:04
questions about behavior
119
364366
1889
pitanja o ponašanju
06:06
are among the easy problems.
120
366255
2925
su među lakim problemima.
06:09
When it comes to the hard problem,
121
369180
1597
Kada je u pitanju težak problem,
06:10
that's the question of why is it
122
370777
2377
to je pitanje
06:13
that all this behavior
123
373154
1811
zašto je sve to ponašanje
06:14
is accompanied by subjective experience?
124
374965
2845
praćeno subjektivnim iskustvom?
06:17
And here, the standard paradigm
125
377810
1755
I ovde, standardna paradigma pojavnosti,
06:19
of emergence,
126
379565
1846
06:21
even the standard paradigms of neuroscience,
127
381411
2947
čak i standardna paradigma neurologije,
06:24
don't really, so far, have that much to say.
128
384358
4443
nemaju zaista, za sada, mnogo toga da kažu.
06:28
Now, I'm a scientific materialist at heart.
129
388801
3645
Ja sam naučni materijalista u srcu.
06:32
I want a scientific theory of consciousness
130
392446
4027
Želim naučnu teoriju svesti
06:36
that works,
131
396473
2329
koja funkcioniše,
06:38
and for a long time, I banged my head
132
398802
2407
i dugo vremena sam udarao glavom o zid
06:41
against the wall
133
401209
1441
06:42
looking for a theory of consciousness
134
402650
2137
tragajući za teorijom svesti
06:44
in purely physical terms
135
404787
1756
u čistim fizičkim terminima
06:46
that would work.
136
406543
1327
koja bi funkcionisala.
06:47
But I eventually came to the conclusion
137
407870
1743
Ali sam najzad došao do zaključka da to prosto nije funkcionisalo
06:49
that that just didn't work for systematic reasons.
138
409613
4185
zbog sistematskih razloga.
06:53
It's a long story,
139
413798
1935
Duga je to priča, ali suštinska ideja
06:55
but the core idea is just that what you get
140
415733
2717
je da ono što dobijate iz potpuno redukcionističkih objašnjenja
06:58
from purely reductionist explanations
141
418450
2340
07:00
in physical terms, in brain-based terms,
142
420790
2644
u fizičkim terminima na osnovi mozga,
07:03
is stories about the functioning of a system,
143
423434
2115
u pričama o funkcionisanju sistema,
07:05
its structure, its dynamics,
144
425549
2126
njegove strukture, njegove dinamike,
07:07
the behavior it produces,
145
427675
1992
ponašanja koje proizvodi,
07:09
great for solving the easy problems —
146
429667
2080
sjajno za rešavanje lakih problema --
07:11
how we behave, how we function —
147
431747
2498
kako se ponašamo, kako funkcionišemo -
07:14
but when it comes to subjective experience —
148
434245
3453
ali kada se radi o subjektivnom iskustvu -
07:17
why does all this feel like something from the inside? —
149
437698
3561
zašto sve to deluje kao nešto iznutra? -
07:21
that's something fundamentally new,
150
441259
2075
to je nešto fundamentalno novo,
07:23
and it's always a further question.
151
443334
3893
i to je uvek dodatno pitanje.
07:27
So I think we're at a kind of impasse here.
152
447227
5413
Tako da mislimo da smo ovde u ćorsokaku.
07:32
We've got this wonderful, great chain of explanation,
153
452640
3215
Imamo te divne, velike sisteme objašnjenja,
07:35
we're used to it, where physics explains chemistry,
154
455855
3600
navikli smo na njih, gde fizika objašnjava hemiju,
07:39
chemistry explains biology,
155
459455
3240
hemija objašnjava biologiju,
07:42
biology explains parts of psychology.
156
462695
3847
biologija objašnjava delove psihologije.
07:46
But consciousness
157
466542
1458
Ali svest
07:48
doesn't seem to fit into this picture.
158
468000
2771
izgleda da se ne uklapa u ovu sliku.
07:50
On the one hand, it's a datum
159
470771
1890
Sa jedne strane, činjenica je
07:52
that we're conscious.
160
472661
1969
da smo svesni.
07:54
On the other hand, we don't know how
161
474630
1286
Sa druge strane, ne znamo kako da to prilagodimo
07:55
to accommodate it into our scientific view of the world.
162
475916
3978
našem naučnom pogledu na svet.
07:59
So I think consciousness right now
163
479894
1947
Mislim da je svest u ovom trenutku
08:01
is a kind of anomaly,
164
481841
2463
vrsta anomalije, vrsta koju moramo da integrišemo
08:04
one that we need to integrate
165
484304
2036
u naš pogled na svet, ali još uvek ne vidimo kako.
08:06
into our view of the world, but we don't yet see how.
166
486340
3900
08:10
Faced with an anomaly like this,
167
490240
1928
Suočeni sa ovakvom anomalijom, radikalne ideje mogu biti potrebne,
08:12
radical ideas may be needed,
168
492168
3239
08:15
and I think that we may need one or two ideas
169
495407
3005
i mislim da možda imamo ideju ili dve
08:18
that initially seem crazy
170
498412
2440
koje se najpre čine ludim
08:20
before we can come to grips with consciousness
171
500852
2936
pre nego što se možemo uhvatiti u koštac sa svešću
08:23
scientifically.
172
503788
2092
naučno.
08:25
Now, there are a few candidates
173
505880
1599
Postoji nekoliko kandidata
08:27
for what those crazy ideas might be.
174
507479
2496
za to koje to lude ideje mogu biti.
08:29
My friend Dan Dennett, who's here today, has one.
175
509975
4342
Moj prijatelj Den Denet, koji je danas ovde, ima jednu takvu.
08:34
His crazy idea is that there is no hard problem
176
514317
2397
Njegova luda ideja je da nema teških problema svesti.
08:36
of consciousness.
177
516714
1743
08:38
The whole idea of the inner subjective movie
178
518457
3363
Cela ideja o unutrašnjem subjektivnom filmu
08:41
involves a kind of illusion or confusion.
179
521820
4612
podrazumeva vrstu iluzije ili zbrke. Zapravo, sve što treba da uradimo
08:46
Actually, all we've got to do is explain
180
526432
1898
je da objasnimo objektivne funkcije, ponašanja mozga,
08:48
the objective functions, the behaviors of the brain,
181
528330
3007
08:51
and then we've explained everything
182
531337
2025
i onda smo objasnili sve
08:53
that needs to be explained.
183
533362
2475
što treba da bude objašnjeno.
08:55
Well I say, more power to him.
184
535837
2609
Pa, više moći za njega.
08:58
That's the kind of radical idea
185
538446
2014
To je vrsta radikalne ideje
09:00
that we need to explore
186
540460
1924
gde treba da istražujemo
09:02
if you want to have a purely reductionist
187
542384
2339
ako želite da imate sasvim redukcionističke
09:04
brain-based theory of consciousness.
188
544723
3550
teorije o svesti zasnovane na mozgu.
09:08
At the same time, for me and for many other people,
189
548273
2071
Istovremeno, za mene i mnoge druge,
09:10
that view is a bit too close to simply
190
550344
1827
taj pogled je malo previše blizu
09:12
denying the datum of consciousness
191
552171
2021
prostom poricanju činjenice svesnosti
09:14
to be satisfactory.
192
554192
1503
da bi bila zadovoljavajuća.
09:15
So I go in a different direction.
193
555695
3068
Tako da idem u drugačijem pravcu.
09:18
In the time remaining,
194
558763
1186
Za preostalo vreme,
09:19
I want to explore two crazy ideas
195
559949
2999
želim da istražim dve lude ideje
09:22
that I think may have some promise.
196
562948
3717
za koje mislim da obećavaju.
09:26
The first crazy idea
197
566665
1620
Prva luda ideja je da je svest fundamentalna.
09:28
is that consciousness is fundamental.
198
568285
4625
Fizičari ponekad uzimaju neke aspekte univerzuma
09:32
Physicists sometimes take some aspects of the universe
199
572910
2841
09:35
as fundamental building blocks:
200
575751
2160
kao fundamentalne temelje:
09:37
space and time and mass.
201
577911
3749
prostor i vreme i masu.
09:41
They postulate fundamental laws governing them,
202
581660
3610
Oni postuliraju fundamentalne zakone koji upravljaju njima,
09:45
like the laws of gravity or of quantum mechanics.
203
585270
3890
kao što su zakoni gravitacije ili kvantne mehanike.
Ova fundamentalna svojstva i zakoni
09:49
These fundamental properties and laws
204
589160
2310
09:51
aren't explained in terms of anything more basic.
205
591470
3217
nisu objašnjena u pogledu bilo čega drugog bazičnijeg.
09:54
Rather, they're taken as primitive,
206
594687
2740
Umesto toga, uzeti su kao primitivi,
09:57
and you build up the world from there.
207
597427
3379
i odatle gradite svet.
10:00
Now sometimes, the list of fundamentals expands.
208
600806
5099
Ponekad, lista fundamentalnih stvari se proširuje.
10:05
In the 19th century, Maxwell figured out
209
605905
2457
U 19. veku, Maksvel je otkrio
10:08
that you can't explain electromagnetic phenomena
210
608362
3168
da ne možete objasniti elektomagnetni fenomen
10:11
in terms of the existing fundamentals —
211
611530
2351
u odnosu na postojeće fundamentalnosti -
10:13
space, time, mass, Newton's laws —
212
613881
3069
prostor, vreme, masu, Njutnove zakone -
10:16
so he postulated fundamental laws
213
616950
2571
pa je postulirao fundamentalne zakone
10:19
of electromagnetism
214
619521
1814
elekromagnetizma
10:21
and postulated electric charge
215
621335
2411
i postulirao je električni napon
10:23
as a fundamental element
216
623746
1768
kao fundamentalni element
10:25
that those laws govern.
217
625514
2959
kojim ti zakoni upravljaju.
10:28
I think that's the situation we're in
218
628473
3283
Mislim da je to situacija u kojoj smo
10:31
with consciousness.
219
631756
1610
sa svešću.
10:33
If you can't explain consciousness
220
633366
2485
Ako ne možete objasniti svest
10:35
in terms of the existing fundamentals —
221
635851
2418
u odnosu na postojeće fundamentalnosti -
10:38
space, time, mass, charge —
222
638269
2671
prostor, vreme, masu, napon -
10:40
then as a matter of logic, you need to expand the list.
223
640940
3430
onda, logično, morate da proširite listu.
10:44
The natural thing to do is to postulate
224
644370
2476
Prirodna stvar koju treba uraditi jeste postulirati samu svest
10:46
consciousness itself as something fundamental,
225
646846
3256
kao nešto fundamentalno,
10:50
a fundamental building block of nature.
226
650102
3032
fundamentalni temelj prirode.
10:53
This doesn't mean you suddenly can't do science with it.
227
653134
2968
To ne znači da se odjednom ne možete baviti naukom bez nje.
10:56
This opens up the way for you to do science with it.
228
656102
3598
Ovo stvara način da se bavite naukom sa njom.
10:59
What we then need is to study
229
659700
1904
Ono što nam je zatim potrebno
11:01
the fundamental laws governing consciousness,
230
661604
2953
je da proučavamo fundamentalne zakone
koji upravljaju svešću,
11:04
the laws that connect consciousness
231
664557
2380
zakone koji povezuju svest
11:06
to other fundamentals: space, time, mass,
232
666937
2801
sa drugim fundamentalnostima: prostorom, vremenom, masom,
11:09
physical processes.
233
669738
2936
fizičkim procesima.
11:12
Physicists sometimes say
234
672674
2182
Fizičari ponekad kažu
11:14
that we want fundamental laws so simple
235
674856
2880
da želimo tako jednostavne fundamentalne zakone
11:17
that we could write them on the front of a t-shirt.
236
677736
3802
da bismo ih mogli napisati na prednjoj strani majice.
11:21
Well I think something like that is the situation
237
681538
1721
Mislim da je tome slična i situacija
11:23
we're in with consciousness.
238
683259
1868
u kojoj smo sa svešću.
11:25
We want to find fundamental laws so simple
239
685127
2750
Želimo da pronađemo tako proste fundamentalne zakone
11:27
we could write them on the front of a t-shirt.
240
687877
2087
da ih možemo napisati na prednjoj strani majice.
11:29
We don't know what those laws are yet,
241
689964
1575
Još uvek ne znamo koji su to zakoni,
11:31
but that's what we're after.
242
691539
4027
ali to je ono za čime tragamo.
11:35
The second crazy idea
243
695566
2417
Druga luda ideja
11:37
is that consciousness might be universal.
244
697983
3478
je da bi svest mogla biti univerzalna.
11:41
Every system might have some degree
245
701461
3061
Svaki sistem može imati izvestan stepen
11:44
of consciousness.
246
704522
3725
svesnosti.
Ovo gledište se ponekad naziva panpsihizmom:
11:48
This view is sometimes called panpsychism:
247
708247
2961
11:51
pan for all, psych for mind,
248
711208
3002
pan za sve, psiha za dušu,
11:54
every system is conscious,
249
714210
1771
svaki sistem je svestan,
11:55
not just humans, dogs, mice, flies,
250
715981
4247
ne samo ljudi, psi, miševi, muve,
12:00
but even Rob Knight's microbes,
251
720228
2577
već čak i mikrobi Roba Najta,
12:02
elementary particles.
252
722805
2187
elementarne čestice.
12:04
Even a photon has some degree of consciousness.
253
724992
2713
Čak i foton ima izvestan stepen svesnosti.
12:07
The idea is not that photons are intelligent
254
727705
3779
Ideja nije u tome da su fotoni inteligentni
12:11
or thinking.
255
731484
1077
ili da misle.
12:12
It's not that a photon
256
732561
1430
Foton nije razoren strepnjom
12:13
is wracked with angst
257
733991
1445
jer misli: "Aaa, ja uvek zujim okolo skoro brzinom svestlosti.
12:15
because it's thinking, "Aww, I'm always buzzing around near the speed of light.
258
735436
3292
12:18
I never get to slow down and smell the roses."
259
738728
2992
Nikada ne stignem da usporim i pomirišem ruže."
12:21
No, not like that.
260
741720
2144
Ne, nije tako.
12:23
But the thought is maybe photons might have
261
743864
3048
Ali misli se da bi fotoni možda mogli imati
12:26
some element of raw, subjective feeling,
262
746912
2623
neke elemente sirovog, subjektivnog osećaja,
12:29
some primitive precursor to consciousness.
263
749535
4152
nekog primitivnog prethodnika svesti.
12:33
This may sound a bit kooky to you.
264
753687
2854
Ovo vam može zvučati pomalo čudno.
12:36
I mean, why would anyone think such a crazy thing?
265
756541
2783
Mislim, zašto bi iko mislio nešto tako suludo?
12:39
Some motivation comes from the first crazy idea,
266
759324
3560
Nešto motivacije potiče iz prve lude ideje,
12:42
that consciousness is fundamental.
267
762884
2146
da je svest fundamentalna.
12:45
If it's fundamental, like space and time and mass,
268
765030
4375
Ako je fundamentalna, kao prostor i vreme i masa,
12:49
it's natural to suppose that it might be universal too,
269
769405
2665
prirodno je pretpostaviti da takođe može biti i univerzalna,
12:52
the way they are.
270
772070
1900
onako kako su i oni.
12:53
It's also worth noting that although the idea
271
773970
1949
Takođe je vredno pomena da iako se ideja
12:55
seems counterintuitive to us,
272
775919
2024
nama čini kontraintuitivnom,
12:57
it's much less counterintuitive to people
273
777943
2744
mnogo je manje kontraintuitivna ljudima
13:00
from different cultures,
274
780687
1731
iz drugačijih kultura,
13:02
where the human mind is seen as much more
275
782418
1520
gde se čini da je ljudski um mnogo više
13:03
continuous with nature.
276
783938
3072
u skladu sa prirodom.
13:07
A deeper motivation comes from the idea that
277
787010
3734
Dublja motivacija potiče od ideje da
13:10
perhaps the most simple and powerful way
278
790744
2009
možda najjednostavniji i najsnažniji način
13:12
to find fundamental laws connecting consciousness
279
792753
2234
za pronalaženje fundamentalnih zakona
13:14
to physical processing
280
794987
1980
koji povezuju svest sa fizičkim procesima
13:16
is to link consciousness to information.
281
796967
3095
jeste povezati svest sa informacijom.
13:20
Wherever there's information processing,
282
800062
2011
Gde god da se obrađuju informacije
13:22
there's consciousness.
283
802073
1065
tu je svest.
13:23
Complex information processing, like in a human,
284
803138
2540
Kompleksna obrada informacija, kao kod ljudi,
13:25
complex consciousness.
285
805688
1532
kompleksna svest.
13:27
Simple information processing,
286
807220
2129
Jednostavna obrada informacija,
13:29
simple consciousness.
287
809349
1958
jednostavna svest.
13:31
A really exciting thing is in recent years
288
811307
2331
Zaista uzbudljiva stvar poslednjih godina:
13:33
a neuroscientist, Giulio Tononi,
289
813638
3265
neurolog Đulio Tononi
13:36
has taken this kind of theory
290
816903
1243
je usvojio ovu vrstu teorije
13:38
and developed it rigorously
291
818146
2075
i rigorozno je razvio
13:40
with a mathematical theory.
292
820221
1849
matematičkom teorijom.
13:42
He has a mathematical measure
293
822070
1517
On ima matematičku meru
13:43
of information integration
294
823587
1730
integracije informacija
13:45
which he calls phi,
295
825317
1919
koju zove fi,
13:47
measuring the amount of information
296
827236
1607
mereći količinu informacija
13:48
integrated in a system.
297
828843
1620
integrisanih u sistemu.
13:50
And he supposes that phi goes along
298
830463
2369
I pretpostavlja da fi ide uporedo
13:52
with consciousness.
299
832832
1438
sa svesnošću.
13:54
So in a human brain,
300
834270
1321
Tako da u ljudskom mozgu, neverovatno velika
13:55
incredibly large amount of information integration,
301
835591
2519
količina integracije informacija,
13:58
high degree of phi,
302
838110
2034
visok stepen fi,
14:00
a whole lot of consciousness.
303
840144
1549
mnogo svesti.
14:01
In a mouse, medium degree of information integration,
304
841693
3693
Kod miša, srednji stepen
integracije informacija, još uvek značajno,
14:05
still pretty significant,
305
845386
1019
14:06
pretty serious amount of consciousness.
306
846405
2025
ozbiljna količina svesnosti.
14:08
But as you go down to worms,
307
848430
2265
Ali kako idete niže ka crvima,
14:10
microbes, particles,
308
850695
3477
mikrobima, česticama,
14:14
the amount of phi falls off.
309
854172
1534
količina fi opada.
14:15
The amount of information integration falls off,
310
855706
2433
Količina integracije informacija opada, ali i dalje nije nula.
14:18
but it's still non-zero.
311
858139
1448
14:19
On Tononi's theory,
312
859587
1939
Po Tononijevoj teoriji,
14:21
there's still going to be a non-zero degree
313
861526
2207
još će biti stepena svesti iznad nule.
14:23
of consciousness.
314
863733
1829
14:25
In effect, he's proposing a fundamental law
315
865562
2539
U suštini, on predlaže fundamentalni zakon svesti:
14:28
of consciousness: high phi, high consciousness.
316
868101
3384
visok fi, visoka svesnost.
14:31
Now, I don't know if this theory is right,
317
871485
2622
Sad, ne znam da li je ova teorija ispravna,
14:34
but it's actually perhaps the leading theory right now
318
874107
3211
ali to je zapravo možda vodeća teorija sada
14:37
in the science of consciousness,
319
877318
1386
u nauci o svesti,
14:38
and it's been used to integrate a whole range
320
878704
2231
i korišćena je da integriše veliki opseg
14:40
of scientific data,
321
880935
2387
naučnih podataka,
14:43
and it does have a nice property that it is in fact simple enough
322
883322
2243
i ima lepo svojstvo da je zapravo dovoljno prosta
14:45
you can write it on the front of a t-shirt.
323
885565
3495
da je možete napisati na prednjoj strani majice.
14:49
Another final motivation is that
324
889060
2625
Još jedna konačna motivacija
14:51
panpsychism might help us to integrate
325
891685
2051
je da bi nam panpsihizam mogao pomoći da integrišemo
14:53
consciousness into the physical world.
326
893736
3214
svest u fizički svet.
14:56
Physicists and philosophers have often observed
327
896950
3177
Fizičari i filozofi su često primećivali
15:00
that physics is curiously abstract.
328
900127
2441
da je fizika neobično apstraktna.
15:02
It describes the structure of reality
329
902568
2148
Opisuje strukturu realnosti
15:04
using a bunch of equations,
330
904716
2084
koristeći gomilu jednačina, ali ne govori nam
15:06
but it doesn't tell us about the reality
331
906800
3024
o stvarnosti koja leži ispod toga.
15:09
that underlies it.
332
909824
1568
15:11
As Stephen Hawking puts it,
333
911392
1897
Kako Stiven Hokin kaže,
15:13
what puts the fire into the equations?
334
913289
4054
šta stavlja vatru u jednačine?
15:17
Well, on the panpsychist view,
335
917343
2618
Pa, sa gledišta panpsihiste,
15:19
you can leave the equations of physics as they are,
336
919961
2639
možete ostaviti jednačine fizike takvim kakve jesu,
15:22
but you can take them to be describing
337
922600
1564
ali možete ih uzeti da opisuju
15:24
the flux of consciousness.
338
924164
1674
tok svesti.
15:25
That's what physics really is ultimately doing,
339
925838
2038
To je ono što fizika zapravo
15:27
describing the flux of consciousness.
340
927876
2329
naposletku radi, opisuje tok svesti.
15:30
On this view, it's consciousness
341
930205
1653
Prema ovom gledištu, svest je ta
15:31
that puts the fire into the equations.
342
931858
4246
koja stavlja vatru u jednačine.
15:36
On that view, consciousness doesn't dangle
343
936104
1660
Prema tom gledištu, svest ne visi
15:37
outside the physical world
344
937764
1676
izvan fizičkog sveta
15:39
as some kind of extra.
345
939440
1418
kao neka vrsta dodatka.
15:40
It's there right at its heart.
346
940858
3456
Ona je baš tu u njegovom srcu.
15:44
This view, I think, the panpsychist view,
347
944314
2874
Ovo gledište, ja mislim, panpsihističko gledište
15:47
has the potential to transfigure our relationship
348
947188
3301
ima potencijal da preokrene naš odnos
15:50
to nature,
349
950489
1495
prema prirodi,
15:51
and it may have some pretty serious social
350
951984
2235
i može imati neke prilično ozbiljne socijalne
15:54
and ethical consequences.
351
954219
3693
i etičke posledice.
15:57
Some of these may be counterintuitive.
352
957912
2159
Neke od njih mogu biti kontraintuitivne.
16:00
I used to think I shouldn't eat anything
353
960071
3071
Nekada sam mislio da ne treba da jedem ništa
16:03
which is conscious,
354
963142
2462
što je svesno,
16:05
so therefore I should be vegetarian.
355
965604
2604
pa bi prema tome trebalo da budem vegetarijanac.
Sad, ako ste panpsihista i usvajate to gledište,
16:08
Now, if you're a panpsychist and you take that view,
356
968208
2567
16:10
you're going to go very hungry.
357
970775
2730
veoma ćete ogladneti.
16:13
So I think when you think about it,
358
973505
1288
Dakle mislim da, kada razmislite o tome, ovo teži da preobrati vaša gledišta,
16:14
this tends to transfigure your views,
359
974793
2167
16:16
whereas what matters for ethical purposes
360
976960
2243
imajući u vidu da ono što je važno
16:19
and moral considerations,
361
979203
1274
za etičke svrhe i moralna razmatranja,
16:20
not so much the fact of consciousness,
362
980477
3077
nije toliko činjenica o svesnosti,
16:23
but the degree and the complexity of consciousness.
363
983554
3956
već stepen i kompleksnost svesnosti.
16:27
It's also natural to ask about consciousness
364
987510
1938
Takođe je prirodno pitati se o svesti
16:29
in other systems, like computers.
365
989448
3050
u drugim sistemima, kao što su kompjuteri.
16:32
What about the artificially intelligent system
366
992498
1789
Šta je sa sistemom veštačke inteligencije
16:34
in the movie "Her," Samantha?
367
994287
3442
u filmu "Ona", Samanta?
16:37
Is she conscious?
368
997729
1400
Da li je ona svesna?
16:39
Well, if you take the informational,
369
999129
1431
Pa, ako uzmete informaciono,
16:40
panpsychist view,
370
1000560
1180
panpsihističko gledište,
16:41
she certainly has complicated information processing
371
1001740
3471
ona svakako ima komplikovanu obradu
16:45
and integration,
372
1005211
1421
i integraciju informacija,
16:46
so the answer is very likely yes, she is conscious.
373
1006632
2667
pa je vrlo verovatno da je odgovor da, ona je svesna.
16:49
If that's right, it raises pretty serious
374
1009299
2938
Ako je to tačno, to pokreće prilično ozbiljna
16:52
ethical issues about both the ethics
375
1012237
2365
etička pitanja,
kako o etici razvijanja inteligentnih kompjuterskih sistema,
16:54
of developing intelligent computer systems
376
1014602
3521
16:58
and the ethics of turning them off.
377
1018123
2736
tako i o etici njihovog isključivanja.
17:00
Finally, you might ask about the consciousness
378
1020859
2500
Konačno, možete se zapitati
17:03
of whole groups,
379
1023359
1882
o svesti čitavih grupa,
17:05
the planet.
380
1025241
1837
planete.
17:07
Does Canada have its own consciousness?
381
1027078
2923
Da li Kanada ima svoju sopstvenu svest?
17:10
Or at a more local level,
382
1030001
2099
Ili više na lokalnom nivou,
da li integrisana grupa kao što je publika na TED konferenciji,
17:12
does an integrated group
383
1032100
1208
17:13
like the audience at a TED conference,
384
1033308
2263
17:15
are we right now having a collective TED consciousness,
385
1035571
3449
da li mi upravo sada imamo kolektivnu TED svest,
unutrašnji film za ovu kolektivnu TED grupu
17:19
an inner movie
386
1039020
1493
17:20
for this collective TED group
387
1040513
2806
koji se razlikuje od unutrašnjih filmova
17:23
which is distinct from the inner movies
388
1043319
1680
17:24
of each of our parts?
389
1044999
1089
svakog od naših delova?
17:26
I don't know the answer to that question,
390
1046088
2155
Ne znam odgovor na to pitanje, ali mislim
17:28
but I think it's at least one
391
1048253
1371
17:29
worth taking seriously.
392
1049624
2474
da bar njega vredi uzeti za ozbiljno.
17:32
Okay, so this panpsychist vision,
393
1052098
2337
Okej, dakle ova panpsihistička vizija,
17:34
it is a radical one,
394
1054435
1813
ona je radikalna,
17:36
and I don't know that it's correct.
395
1056248
2214
i ne znam da li je ispravna.
17:38
I'm actually more confident about
396
1058462
1853
Zapravo sam mnogo sigurniji
17:40
the first crazy idea,
397
1060315
1633
u vezi sa prvom ludom idejom,
17:41
that consciousness is fundamental,
398
1061948
2169
da je svest fundamentalna,
17:44
than about the second one,
399
1064117
1803
nego drugom,
17:45
that it's universal.
400
1065920
2221
da je univerzalna.
17:48
I mean, the view raises any number of questions,
401
1068141
2078
Mislim, gledište pokreće veliki broj pitanja,
17:50
has any number of challenges,
402
1070219
1541
ima veliki broj izazova,
17:51
like how do those little bits
403
1071760
1360
kao što je kako oni mali delovi
17:53
of consciousness add up
404
1073120
1740
svesti dodaju
17:54
to the kind of complex consciousness
405
1074860
2297
do kompleksne svesnosti koju znamo i volimo.
17:57
we know and love.
406
1077157
2323
Ako možemo odgovoriti na ta pitanja,
17:59
If we can answer those questions,
407
1079480
1460
18:00
then I think we're going to be well on our way
408
1080940
1505
onda mislim da ćemo biti na dobrom putu ka ozbiljnoj teoriji svesti.
18:02
to a serious theory of consciousness.
409
1082445
3087
18:05
If not, well, this is the hardest problem perhaps
410
1085532
3388
Ako ne, pa, ovo je možda najteži problem
18:08
in science and philosophy.
411
1088920
1844
u nauci i filozofiji.
18:10
We can't expect to solve it overnight.
412
1090764
3445
Ne možemo očekivati da će se rešiti preko noći.
Ali mislim da ćemo ga shvatiti na kraju.
18:14
But I do think we're going to figure it out eventually.
413
1094209
3540
18:17
Understanding consciousness is a real key, I think,
414
1097749
2987
Razumeti svest je pravi ključ, ja mislim,
18:20
both to understanding the universe
415
1100736
2452
kako za razumevanje univerzuma
18:23
and to understanding ourselves.
416
1103188
2530
tako i za razumevanje nas samih.
18:25
It may just take the right crazy idea.
417
1105718
2903
Možda je samo potrebna prava suluda ideja.
18:28
Thank you.
418
1108621
1991
Hvala vam.
