ABOUT THE SPEAKER
Stephen Cave - Philosopher
Philosopher Stephen Cave wants to know: Why is humanity so obsessed with living forever?

Why you should listen

Stephen Cave is a writer and philosopher who is obsessed with our obsession with immortality. In 2012 he published Immortality: The Quest to Live Forever and How It Drives Civilization, an inquiry into humanity's rather irrational resistance to the inevitability of death. Cave moves across time and history's major civilizations and religions to explore just what drives this instinct -- and what that means for the future. Cave writes for The Financial Times and contributes to The New York Times, The Guardian and Wired.

O filósofo Stephen Cave comeza cunha pregunta escura pero atractiva: cando te deches conta por primeira vez de que ías morrer? E aínda máis interesante, como facemos os humanos para resistirnos á certeza da morte? Nunha conferencia fascinante, Cave explora catro historias, comúns en todas as civilizacións, que nos contamos a nós mesmos "co obxecto de axudarnos a xestionar o terror á morte"

I have a question:
0
378
1893
Teño unha pregunta:
00:14
Who here remembers when they first realized
1
2271
3377
Quen dos presentes recorda
a primeira vez que se deu conta
00:17
they were going to die?
2
5648
3423
de que ía morrer?
00:21
I do. I was a young boy,
3
9071
2502
Eu si. Era un neno pequeno,
00:23
and my grandfather had just died,
4
11573
3055
o meu avó acababa de morrer,
00:26
and I remember a few days later lying in bed at night
5
14628
3918
e recordo estar uns días despois na cama,
00:30
trying to make sense of what had happened.
6
18546
3634
intentando atoparlle sentido
ao que sucedera.
00:34
What did it mean that he was dead?
7
22180
2635
Que significaba que estivera morto?
00:36
Where had he gone?
8
24815
1784
A onde fora?
00:38
It was like a hole in reality had opened up
9
26599
3422
Era coma se se abrira
un buraco na realidade
00:42
and swallowed him.
10
30021
2135
e o engulira.
00:44
But then the really shocking
question occurred to me:
11
32156
2802
Pero logo ocorréuseme
a cuestión máis impactante:
00:46
If he could die, could it happen to me too?
12
34958
3490
se el morrera, podería
pasarme a min tamén?
00:50
Could that hole in reality open up and swallow me?
13
38448
3299
Podería ese buraco na realidade
abrirse e engulirme a min?
00:53
Would it open up beneath my bed
14
41747
1790
Abriríase debaixo da miña cama
00:55
and swallow me as I slept?
15
43537
3234
e tragaríame mentres durmía?
00:58
Well, at some point, all children
become aware of death.
16
46771
4188
Ben, nalgún momento, todos os cativos
toman consciencia da morte.
01:02
It can happen in different ways, of course,
17
50959
1905
Pode suceder de distintos xeitos,
01:04
and usually comes in stages.
18
52864
1833
e adoita suceder por fases.
01:06
Our idea of death develops as we grow older.
19
54697
3513
A nosa idea da morte desenvólvese
a medida que envellecemos.
01:10
And if you reach back into the dark corners
20
58210
2729
E se rebuscas nos recantos agochados
01:12
of your memory,
21
60939
1697
da túa memoria,
01:14
you might remember something like what I felt
22
62636
3003
se cadra recordas algo
similar ao que sentín
01:17
when my grandfather died and when I realized
23
65639
3255
cando o meu avó morreu, e me dei conta
01:20
it could happen to me too,
24
68894
1950
de que me podería pasar a min tamén,
01:22
that sense that behind all of this
25
70844
2579
esa sensación de que, detrás de todo isto,
01:25
the void is waiting.
26
73423
3337
espera o baleiro.
01:28
And this development in childhood
27
76760
2277
E esta evolución na infancia
01:31
reflects the development of our species.
28
79037
2821
reflicte a evolución da nosa especie.
01:33
Just as there was a point in your development
29
81858
3315
Tal como houbo un punto
no teu desenvolvemento de neno
01:37
as a child when your sense of self and of time
30
85173
3526
en que a consciencia
de ti mesmo e do tempo
01:40
became sophisticated enough
31
88699
2099
se volveu o suficientemente complexa
01:42
for you to realize you were mortal,
32
90798
3922
como para darte conta de que es mortal,
01:46
so at some point in the evolution of our species,
33
94720
3706
nalgún punto da evolución da nosa especie,
01:50
some early human's sense of self and of time
34
98426
3015
a conciencia dun mesmo e do tempo
dos antigos humanos
01:53
became sophisticated enough
35
101441
2243
volveuse o suficientemente complexa
01:55
for them to become the first human to realize,
36
103684
3115
como para convertérense nos primeiros
humanos en decatarse:
01:58
"I'm going to die."
37
106799
3433
"Vou morrer".
Esta é, se se quere ver así,
a nosa maldición.
02:02
This is, if you like, our curse.
38
110232
2219
02:04
It's the price we pay for being so damn clever.
39
112451
4043
É o prezo de ser
tan condenadamente intelixentes.
02:08
We have to live in the knowledge
40
116494
2099
Temos que vivir sabendo
02:10
that the worst thing that can possibly happen
41
118593
2661
que a peor cousa que pode pasar,
02:13
one day surely will,
42
121254
1624
un día pasará,
02:14
the end of all our projects,
43
122878
1506
a fin de todos os proxectos,
02:16
our hopes, our dreams, of our individual world.
44
124384
3464
esperanzas, soños,
do noso mundo individual.
02:19
We each live in the shadow of a personal
45
127848
3181
Cada un de nós vive na sombra
dunha apocalipse persoal.
02:23
apocalypse.
46
131029
1989
02:25
And that's frightening. It's terrifying.
47
133018
2504
E iso asusta, é aterrador.
02:27
And so we look for a way out.
48
135522
2460
Entón buscamos unha saída.
02:29
And in my case, as I was about five years old,
49
137982
3281
E no meu caso, como tiña cinco anos,
02:33
this meant asking my mum.
50
141263
2995
foi preguntarlle á miña nai.
02:36
Now when I first started asking
51
144258
2462
Cando comecei a preguntar
02:38
what happens when we die,
52
146720
1781
que ocorre ao morrer,
02:40
the grown-ups around me at the time
53
148501
2092
os adultos do meu redor nese momento
02:42
answered with a typical English mix of awkwardness
54
150593
3203
contestaban cunha típica mestura inglesa
de incomodidade
02:45
and half-hearted Christianity,
55
153796
2987
e cristianismo sen moita convicción,
02:48
and the phrase I heard most often
56
156783
1944
e a frase que oín máis a miúdo
02:50
was that granddad was now
57
158727
1559
era que o avó agora estaba
02:52
"up there looking down on us,"
58
160286
2464
"aí arriba mirándonos",
e que se eu tivese que morrer,
o que por suposto non ía pasar,
02:54
and if I should die too, which
wouldn't happen of course,
59
162750
2965
02:57
then I too would go up there,
60
165715
2796
entón eu tamén iría para alá arriba,
03:00
which made death sound a lot like
61
168511
2050
o que fixo que a morte me soase bastante
03:02
an existential elevator.
62
170561
2654
a un ascensor existencial.
03:05
Now this didn't sound very plausible.
63
173215
3118
Isto non soaba moi realista.
03:08
I used to watch a children's
news program at the time,
64
176333
2903
Adoitaba ver daquela
un programa infantil de novas,
03:11
and this was the era of space exploration.
65
179236
2440
e isto foi na era da exploración espacial.
03:13
There were always rockets going up into the sky,
66
181676
2174
Sempre había foguetes indo ao ceo,
03:15
up into space, going up there.
67
183850
2696
ao espazo, alá arriba.
03:18
But none of the astronauts when they came back
68
186546
2329
Pero ningún dos astronautas ao volver
03:20
ever mentioned having met my granddad
69
188875
3232
mencionou nunca que se atoparan co meu avó
03:24
or any other dead people.
70
192107
2459
ou con calquera outra persoa falecida.
03:26
But I was scared,
71
194566
1303
Pero estaba asustado,
03:27
and the idea of taking the existential elevator
72
195869
2440
e a idea de subir ao ascensor existencial
03:30
to see my granddad
73
198309
1606
para ver o meu avó
03:31
sounded a lot better than being swallowed
74
199915
1415
soaba mellor que ser engulido
03:33
by the void while I slept.
75
201330
3071
polo baleiro mentres durmía.
03:36
And so I believed it anyway,
76
204401
2269
E aínda así crino,
03:38
even though it didn't make much sense.
77
206670
2671
a pesar de non ter moito sentido.
03:41
And this thought process that I went through
78
209341
2242
E este proceso mental que pasei de cativo,
03:43
as a child, and have been through many times since,
79
211583
2531
e que pasei moitas veces desde aquela,
03:46
including as a grown-up,
80
214114
1910
incluso de adulto,
03:48
is a product of what psychologists call
81
216024
2447
é o produto do que os psicólogos chaman
03:50
a bias.
82
218471
1464
un nesgo cognitivo.
03:51
Now a bias is a way in which we systematically
83
219935
3274
Un nesgo é a forma en que por sistema
03:55
get things wrong,
84
223209
1718
interpretamos mal as cousas,
03:56
ways in which we miscalculate, misjudge,
85
224927
2684
a forma en que que calculamos mal,
xulgamos mal,
03:59
distort reality, or see what we want to see,
86
227611
3589
distorsionamos a realidade
ou vemos o que queremos ver,
04:03
and the bias I'm talking about
87
231200
2232
e o nesgo do que falo
04:05
works like this:
88
233432
1438
funciona do seguinte xeito:
04:06
Confront someone with the fact
89
234870
2235
Enfronta alguén co feito
04:09
that they are going to die
90
237105
1547
de que vai morrer
04:10
and they will believe just about any story
91
238652
3033
e crerá calquera historia
04:13
that tells them it isn't true
92
241685
1858
que lle asegure que non é certo,
04:15
and they can, instead, live forever,
93
243543
2414
e que poderá, en lugar diso,
vivir para sempre,
04:17
even if it means taking the existential elevator.
94
245957
4085
incluso aínda que implique
coller o ascensor existencial.
04:22
Now we can see this as the biggest bias of all.
95
250042
4428
Podemos ver isto como
o maior nesgo de todos.
04:26
It has been demonstrated in over 400
96
254470
2875
Demostrouse en máis
de 400 estudos empíricos.
04:29
empirical studies.
97
257345
1681
04:31
Now these studies are ingenious, but they're simple.
98
259026
2509
Estes estudos son enxeñosos,
pero simples,
04:33
They work like this.
99
261535
1935
Funcionan do seguinte xeito:
04:35
You take two groups of people
100
263470
1490
Colles dous grupos de persoas
04:36
who are similar in all relevant respects,
101
264960
2783
que sexan similares en
todos os aspectos significativos,
04:39
and you remind one group that they're going to die
102
267743
2689
e recórdaslle a un dos grupos
que vai morrer
04:42
but not the other, then you compare their behavior.
103
270432
2629
pero ao outro non, e logo comparas
o seu comportamento.
04:45
So you're observing how it biases behavior
104
273061
3873
Así ves como se condiciona o comportamento
04:48
when people become aware of their mortality.
105
276934
3754
cando a xente toma consciencia
da súa propia mortalidade.
04:52
And every time, you get the same result:
106
280688
2912
E sempre obtés o mesmo resultado:
04:55
People who are made aware of their mortality
107
283600
3087
As persoas conscientes da súa mortalidade
04:58
are more willing to believe stories
108
286687
2011
están máis dispostas a crer historias
05:00
that tell them they can escape death
109
288698
1863
que lles din que poden escapar da morte
05:02
and live forever.
110
290561
1772
e vivir para sempre.
05:04
So here's an example: One recent study
111
292333
2289
Aquí vai un exemplo:
Un estudo recente
05:06
took two groups of agnostics,
112
294622
2770
colleu dous grupos de agnósticos,
05:09
that is people who are undecided
113
297392
1596
persoas indecisas acerca
05:10
in their religious beliefs.
114
298988
2515
das súas crenzas relixiosas.
05:13
Now, one group was asked to think about being dead.
115
301503
3584
A un grupo pedíuselle
que pensase en estar morto,
05:17
The other group was asked to think about
116
305087
1645
e ao outro grupo pedíuselle pensar
05:18
being lonely.
117
306732
1833
en estaren sós.
05:20
They were then asked again
about their religious beliefs.
118
308565
2816
Despois preguntóuselles de novo
polas súas crenzas;
05:23
Those who had been asked
to think about being dead
119
311381
2864
aqueles aos que se lles pedira
pensar en estar mortos
05:26
were afterwards twice as likely to express faith
120
314245
3573
eran despois o dobre de propensos
a expresar fe
05:29
in God and Jesus.
121
317818
1660
en Deus e en Xesús.
05:31
Twice as likely.
122
319478
1778
O dobre de propensos.
05:33
Even though the before they
were all equally agnostic.
123
321256
2708
A pesar de que antes
eran todos igual de agnósticos.
05:35
But put the fear of death in them,
124
323964
1761
Pero metéronlles o medo á morte,
05:37
and they run to Jesus.
125
325725
3859
e correron cara a Xesús.
05:41
Now, this shows that reminding people of death
126
329584
3512
Ben, isto mostra
que recordarlle á xente a morte
05:45
biases them to believe, regardless of the evidence,
127
333111
3230
indúceos a crer, a pesar das evidencias,
05:48
and it works not just for religion,
128
336341
2025
e non só funciona coa relixión,
05:50
but for any kind of belief system
129
338366
2237
senón con calquera sistema de crenzas
05:52
that promises immortality in some form,
130
340603
3460
que lles prometa algún xeito
de inmortalidade,
05:56
whether it's becoming famous
131
344063
1805
xa sexa facerse famosos,
05:57
or having children
132
345868
1414
ou ter fillos,
05:59
or even nationalism,
133
347282
1347
ou incluso o nacionalismo,
06:00
which promises you can live
on as part of a greater whole.
134
348629
3273
que che promete que podes vivir
como parte dun todo maior.
06:03
This is a bias that has shaped
135
351902
1931
É un nesgo que condiciounou
06:05
the course of human history.
136
353833
3339
o transcurso da historia da humanidade.
06:09
Now, the theory behind this bias
137
357172
2267
Ben, a teoría tras este nesgo
06:11
in the over 400 studies
138
359439
1737
en máis de 400 estudos
06:13
is called terror management theory,
139
361176
2129
chámase teoría da xestión do terror
06:15
and the idea is simple. It's just this.
140
363305
2350
e a idea é simple. É simplemente isto:
06:17
We develop our worldviews,
141
365655
2549
desenvolvemos os nosos puntos de vista,
06:20
that is, the stories we tell ourselves
142
368204
2157
é dicir, o que nos contamos a nós mesmos
06:22
about the world and our place in it,
143
370361
2736
sobre o mundo e o noso lugar nel
06:25
in order to help us manage
144
373097
2282
co obxecto de axudarnos a xestionar
06:27
the terror of death.
145
375379
2914
o terror á morte.
06:30
And these immortality stories
146
378293
1799
E estas historias de inmortalidade
06:32
have thousands of different manifestations,
147
380092
2997
maniféstanse de miles de maneiras
06:35
but I believe that behind the apparent diversity
148
383089
3584
pero eu creo que tras
a disparidade aparente
06:38
there are actually just four basic forms
149
386673
2699
en realidade hai só catro formas básicas
06:41
that these immortality stories can take.
150
389372
3511
en que se poden presentar estas
historias de inmortalidade.
06:44
And we can see them repeating themselves
151
392883
1805
E podemos ver como se van repetindo
06:46
throughout history, just with slight variations
152
394688
3170
ao longo da historia,
con lixeiras variacións
06:49
to reflect the vocabulary of the day.
153
397858
2765
para reflectir o vocabulario do momento.
06:52
Now I'm going to briefly introduce these four
154
400623
2508
Agora vou presentar brevemente estas catro
06:55
basic forms of immortality story,
155
403131
2253
formas de historias de inmortalidade,
06:57
and I want to try to give you some sense
156
405384
1570
e quero darvos unha idea
06:58
of the way in which they're retold by each culture
157
406954
2313
do xeito en que se repiten en cada cultura
07:01
or generation
158
409267
1767
ou xeración
07:03
using the vocabulary of their day.
159
411034
2172
utilizando o vocabulario do momento.
07:05
Now, the first story is the simplest.
160
413206
2639
Ben, a primeira historia é a máis sinxela.
07:07
We want to avoid death,
161
415845
2153
Queremos evitar a morte,
07:09
and the dream of doing that in this body
162
417998
2425
e o soño de facelo neste corpo,
07:12
in this world forever
163
420423
1360
neste mundo para sempre
07:13
is the first and simplest kind of immortality story,
164
421783
3291
é a primeira e máis simple
historia de inmortalidade,
07:17
and it might at first sound implausible,
165
425074
2459
e se cadra ao primeiro non soa posible,
07:19
but actually, almost every culture in human history
166
427533
3981
pero en realidade, case todas as culturas
na historia da humanidade
07:23
has had some myth or legend
167
431514
2062
tiveron algún tipo de mito ou lenda
07:25
of an elixir of life or a fountain of youth
168
433576
2761
sobre un elixir de vida ou unha fonte
da eterna xuventude
07:28
or something that promises to keep us going
169
436337
2979
ou algo que prometa manternos
07:31
forever.
170
439316
3137
vivos para sempre.
07:34
Ancient Egypt had such myths,
171
442453
1593
O antigo Exipto tiña estes mitos,
07:36
ancient Babylon, ancient India.
172
444046
2368
a antiga Babilonia, a antiga India.
07:38
Throughout European history, we find them
in the work of the alchemists,
173
446414
2852
Na historia europea,
vémolo no traballo dos alquimistas,
07:41
and of course we still believe this today,
174
449266
2794
e, por suposto, aínda o cremos hoxe,
07:44
only we tell this story using the vocabulary
175
452060
2563
só que o contamos usando o vocabulario
07:46
of science.
176
454623
1656
da ciencia.
07:48
So 100 years ago,
177
456279
1606
Así, hai cen anos,
07:49
hormones had just been discovered,
178
457885
1819
descubríronse as hormonas
07:51
and people hoped that hormone treatments
179
459704
1652
e críase que os tratamentos hormonais
07:53
were going to cure aging and disease,
180
461356
2699
curarían o envellecemento e a enfermidade
07:56
and now instead we set our hopes on stem cells,
181
464055
2853
e agora, en troques, poñemos
as esperanzas nas células nai,
07:58
genetic engineering, and nanotechnology.
182
466908
2295
na enxeñaría xenética e a nanotecnoloxía.
08:01
But the idea that science can cure death
183
469203
3958
Pero a idea de que
a ciencia pode curar a morte,
08:05
is just one more chapter in the story
184
473161
2341
é só un capítulo máis da historia
08:07
of the magical elixir,
185
475502
2233
do elixir máxico,
08:09
a story that is as old as civilization.
186
477735
4436
unha historia tan vella
como a civilización.
08:14
But betting everything on the idea of finding the elixir
187
482171
2780
Pero apostar todo á idea
de atopar o elixir
08:16
and staying alive forever
188
484951
1403
e sobrevivir para sempre
08:18
is a risky strategy.
189
486354
1801
é unha estratexia arriscada.
Cando miramos cara a atrás
ao longo da historia
08:20
When we look back through history
190
488155
2240
08:22
at all those who have sought an elixir in the past,
191
490395
2784
cara a todos os que buscaron o elixir,
08:25
the one thing they now have in common
192
493179
1829
o único que teñen en común
08:27
is that they're all dead.
193
495008
2630
é que están todos mortos.
08:29
So we need a backup plan,
and exactly this kind of plan B
194
497638
3738
Así que precisamos un plan de apoio,
e exactamente esta especie de plan B
08:33
is what the second kind of immortality story offers,
195
501376
3571
é o que nos ofrece a segunda
historia de inmortalidade,
08:36
and that's resurrection.
196
504947
1755
e esa é a resurrección.
08:38
And it stays with the idea that I am this body,
197
506702
2374
E mantense na idea de que
eu son este corpo,
08:41
I am this physical organism.
198
509076
1975
son este organismo físico
08:43
It accepts that I'm going to have to die
199
511051
2168
e acepta a idea de ter que morrer,
08:45
but says, despite that,
200
513219
1374
pero di, a pesar diso,
08:46
I can rise up and I can live again.
201
514593
2503
podo levantarme e vivir de novo.
08:49
In other words, I can do what Jesus did.
202
517096
2618
Noutras palabras,
podo facer o que fixo Xesús.
08:51
Jesus died, he was three days in the [tomb],
203
519714
2045
Xesús morreu, estivo tres días na [tumba]
08:53
and then he rose up and lived again.
204
521759
3111
e logo levantouse e viviu de novo.
08:56
And the idea that we can all be
resurrected to live again
205
524870
3119
E a idea de que todos podemos
resucitar e vivir de novo,
08:59
is orthodox believe, not just for Christians
206
527989
2288
é unha crenza ortodoxa
non só para os cristiáns,
09:02
but also Jews and Muslims.
207
530277
2703
senón tamén para os xudeus e os musulmáns.
09:04
But our desire to believe this story
208
532980
2164
Pero o noso desexo de crer esta historia
09:07
is so deeply embedded
209
535144
2010
está tan profundamente arraigado
09:09
that we are reinventing it again
210
537154
2098
que o estamos reinventando de novo
09:11
for the scientific age,
211
539252
1492
para a era da ciencia,
09:12
for example, with the idea of cryonics.
212
540744
2823
por exemplo, coa idea da crionización.
09:15
That's the idea that when you die,
213
543567
1590
Esa é a idea de que ao morrer,
09:17
you can have yourself frozen,
214
545157
1999
podes ser conxelado,
09:19
and then, at some point when technology
215
547156
2389
e logo, no punto en que a tecnoloxía
09:21
has advanced enough,
216
549545
1211
avance abondo,
09:22
you can be thawed out and repaired and revived
217
550756
2120
poderás ser desconxelado,
amañado e revivido
09:24
and so resurrected.
218
552876
1289
e, polo tanto, resucitado.
09:26
And so some people believe an omnipotent god
219
554165
2848
E así, algunha xente cre
que un Deus omnipotente
09:29
will resurrect them to live again,
220
557013
1879
a resucitará para volver á vida,
09:30
and other people believe an
omnipotent scientist will do it.
221
558892
4143
e outra xente cre que o farán
científicos omnipotentes.
09:35
But for others, the whole idea of resurrection,
222
563035
2714
Pero para outros, toda esa idea
da resurrección,
09:37
of climbing out of the grave,
223
565749
2003
de saír gabeando da tumba,
09:39
it's just too much like a bad zombie movie.
224
567752
2719
seméllase demasiado
a unha película mala de zombis.
09:42
They find the body too messy, too unreliable
225
570471
2791
Pensan que o corpo é demasiado
caótico e pouco fiable,
09:45
to guarantee eternal life,
226
573262
2148
para garantir a vida eterna,
09:47
and so they set their hopes on the third,
227
575410
3091
así que deixan as súas expectativas
na terceira
09:50
more spiritual immortality story,
228
578501
2117
e máis espiritual
historia da inmortalidade,
09:52
the idea that we can leave our body behind
229
580618
2336
a idea de que podemos
deixar o corpo atrás,
09:54
and live on as a soul.
230
582954
2297
e continuar vivindo como alma.
09:57
Now, the majority of people on Earth
231
585251
1989
A maioría da xente na Terra
09:59
believe they have a soul,
232
587240
1773
cre que ten unha alma,
10:01
and the idea is central to many religions.
233
589013
2410
e é unha idea fundamental
para moitas relixións
10:03
But even though, in its current form,
234
591423
2314
A pesar de que, na súa forma actual,
10:05
in its traditional form,
235
593737
1915
a máis tradicional,
10:07
the idea of the soul is still hugely popular,
236
595652
2163
a idea de alma é aínda
altamente popular,
10:09
nonetheless we are again
237
597815
1432
aínda estamos aí de novo,
10:11
reinventing it for the digital age,
238
599247
2224
reinventándoa para a era dixital,
10:13
for example with the idea
239
601471
1477
por exemplo, coa idea
10:14
that you can leave your body behind
240
602948
1990
de que podes deixar o corpo atrás
10:16
by uploading your mind, your essence,
241
604938
2246
cargando a mente, a túa esencia,
10:19
the real you, onto a computer,
242
607184
1956
o ti real, nun ordenador,
10:21
and so live on as an avatar in the ether.
243
609140
4612
e continuar vivo polo tanto
como un avatar etéreo.
10:25
But of course there are skeptics who say
244
613752
2023
Por suposto, hai escépticos que din
que se miramos as evidencias da ciencia,
10:27
if we look at the evidence of science,
245
615775
1844
10:29
particularly neuroscience,
246
617619
1644
en concreto da neurociencia,
10:31
it suggests that your mind,
247
619263
1829
suxiren que a túa mente,
10:33
your essence, the real you,
248
621092
1580
a túa esencia, o auténtico ti,
10:34
is very much dependent on a particular part
249
622672
2413
é moi dependente dunha parte
particular do corpo,
10:37
of your body, that is, your brain.
250
625085
2221
que é o cerebro.
10:39
And such skeptics can find comfort
251
627306
2521
E tales escépticos poden atopar consolo
10:41
in the fourth kind of immortality story,
252
629827
2258
no cuarto tipo de
historia de inmortalidade,
10:44
and that is legacy,
253
632085
2357
que é o legado,
10:46
the idea that you can live on
254
634442
1480
a idea de que podes seguir vivo
10:47
through the echo you leave in the world,
255
635922
2251
a través do eco que deixas no mundo,
10:50
like the great Greek warrior Achilles,
256
638173
2349
como o gran guerreiro grego Aquiles,
10:52
who sacrificed his life fighting at Troy
257
640522
2629
que sacrificou a vida loitando en Troia
10:55
so that he might win immortal fame.
258
643151
3053
para así poder lograr unha fama inmortal.
10:58
And the pursuit of fame is as widespread
259
646204
2266
E a persecución da fama está tan estendida
11:00
and popular now as it ever was,
260
648470
2141
e é tan popular como sempre foi,
11:02
and in our digital age,
261
650611
1579
e na nosa era dixital
11:04
it's even easier to achieve.
262
652190
1528
e incluso máis fácil de lograr.
11:05
You don't need to be a great warrior like Achilles
263
653718
2324
Non tes que ser un gran guerreiro
como Aquiles,
11:08
or a great king or hero.
264
656042
1693
nin un gran rei ou heroe.
11:09
All you need is an Internet connection
and a funny cat. (Laughter)
265
657735
4823
Todo o que precisas é unha conexión
a Internet e un gato simpático.
(Risos)
11:14
But some people prefer to leave a more tangible,
266
662558
2463
Pero algunha xente prefire
deixar algo máis tanxible,
11:17
biological legacy -- children, for example.
267
665021
2844
un legado biolóxico, fillos, por exemplo.
11:19
Or they like, they hope, to live on
268
667865
2276
Ou queren, esperan, vivir
11:22
as part of some greater whole,
269
670141
1717
como parte de algo máis grande,
11:23
a nation or a family or a tribe,
270
671858
2449
unha nación ou unha familia ou unha tribo,
11:26
their gene pool.
271
674307
2466
o seu clan xenético.
11:28
But again, there are skeptics
272
676773
1513
Pero, de novo, hai escépticos
11:30
who doubt whether legacy
273
678286
1713
que dubidan de que este legado
11:31
really is immortality.
274
679999
1975
sexa realmente a inmortalidade.
11:33
Woody Allen, for example, who said,
275
681974
2077
Woody Allen, por exemplo, dixo:
11:36
"I don't want to live on in
the hearts of my countrymen.
276
684051
2496
"Non quero seguir vivindo
no corazón dos meus paisanos,
11:38
I want to live on in my apartment."
277
686547
2197
quero seguir vivindo no meu apartamento".
11:40
So those are the four
278
688744
1767
Pois estes son os catro
11:42
basic kinds of immortality stories,
279
690511
2183
tipos básicos de historias
de inmortalidade
11:44
and I've tried to give just some sense
280
692694
1642
e intentei darlle un pouco de sentido
11:46
of how they're retold by each generation
281
694336
2293
a como son repetidas por cada xeración
11:48
with just slight variations
282
696629
1587
con só pequenas variacións
11:50
to fit the fashions of the day.
283
698216
2305
para axustarse ás modas do momento.
11:52
And the fact that they recur in this way,
284
700521
3489
E o feito de que se repitan deste xeito,
11:56
in such a similar form but
in such different belief systems,
285
704010
2988
cunha forma tan similar,
en sistemas de crenzas tan distintos
11:58
suggests, I think,
286
706998
1578
suxire, diría eu,
12:00
that we should be skeptical of the truth
287
708576
2402
que deberiamos ser escépticos
sobre a veracidade
12:02
of any particular version of these stories.
288
710978
3761
de calquera versión concreta
destas historias.
12:06
The fact that some people believe
289
714739
2111
O feito de que algunhas persoas crean
12:08
an omnipotent god will resurrect them to live again
290
716850
2665
nun Deus omnipotente
que as resucitará para vivir de novo
12:11
and others believe an omnipotent scientist will do it
291
719515
3701
e outras crean que o farán
científicos omnipotentes
12:15
suggests that neither are really believing this
292
723216
3038
suxire que ninguén cre isto
12:18
on the strength of the evidence.
293
726254
2670
baseándose na forza das probas.
12:20
Rather, we believe these stories
294
728924
2426
Máis ben, cremos estas historias
12:23
because we are biased to believe them,
295
731350
1983
porque estamos predispostos a crelas,
12:25
and we are biased to believe them
296
733333
1828
e estamos predispostos a crelas
12:27
because we are so afraid of death.
297
735161
4270
porque lle temos moito medo á morte.
12:31
So the question is,
298
739431
2055
Polo tanto, a cuestión é:
12:33
are we doomed to lead the one life we have
299
741486
3472
estamos condenados a levar
a única vida que temos
12:36
in a way that is shaped by fear and denial,
300
744958
3693
dun xeito marcado
polo medo e a negación,
12:40
or can we overcome this bias?
301
748651
3075
ou podemos superar este nesgo?
12:43
Well the Greek philosopher Epicurus
302
751726
2467
Ben, o filósofo grego Epicuro
12:46
thought we could.
303
754193
1728
pensou que podiamos.
12:47
He argued that the fear of death is natural,
304
755921
3548
Argumentaba que o medo á morte é natural,
12:51
but it is not rational.
305
759469
2415
pero non racional.
12:53
"Death," he said, "is nothing to us,
306
761884
2658
"A morte -dicía- non é nada para nós,
12:56
because when we are here, death is not,
307
764542
2850
porque cando nós estamos aquí,
a morte non o está,
12:59
and when death is here, we are gone."
308
767392
3753
e cando a morte está aquí,
nós xa non estamos".
13:03
Now this is often quoted, but it's difficult
309
771145
1798
Isto cítase a miúdo, pero é difícil
13:04
to really grasp, to really internalize,
310
772943
2322
comprendelo de verdade, interiorizalo,
13:07
because exactly this idea of being gone
311
775265
2163
porque exactamente esta idea
de xa non estar
13:09
is so difficult to imagine.
312
777428
2139
é moi difícil de imaxinar.
13:11
So 2,000 years later, another philosopher,
313
779567
2231
Así que 2000 anos despois, outro filósofo,
13:13
Ludwig Wittgenstein, put it like this:
314
781798
3457
Ludwig Wittgenstein, expresouno así:
13:17
"Death is not an event in life:
315
785255
2944
"A morte non é un evento na vida:
13:20
We do not live to experience death.
316
788199
3642
non vivimos para experimentar a morte."
13:23
And so," he added,
317
791841
1194
E polo tanto -engadiu-
13:25
"in this sense, life has no end."
318
793035
2935
"neste sentido, a vida non ten final."
13:27
So it was natural for me as a child
319
795970
3176
Polo que era natural que eu, de neno,
13:31
to fear being swallowed by the void,
320
799146
2367
tivese medo de ser engulido polo baleiro,
13:33
but it wasn't rational,
321
801513
1879
pero non era racional,
13:35
because being swallowed by the void
322
803392
1985
porque ser engulido polo baleiro
13:37
is not something that any of us
323
805377
2078
é algo que ningún de nós
13:39
will ever live to experience.
324
807455
3270
vai poder experimentar.
13:42
Now, overcoming this bias is not easy because
325
810725
2529
Agora, superar este nesgo
non é fácil porque
13:45
the fear of death is so deeply embedded in us,
326
813254
2959
o medo á morte está moi arraigado en nós,
13:48
yet when we see that the fear itself is not rational,
327
816213
4482
aínda así, cando vemos que
o medo en si mesmo non é racional,
13:52
and when we bring out into the open
328
820695
2130
e cando sacamos á luz
13:54
the ways in which it can unconsciously bias us,
329
822825
2698
os xeitos en que inconscientemente
nos condiciona,
13:57
then we can at least start
330
825523
1851
podemos polo menos empezar
13:59
to try to minimize the influence it has
331
827374
2634
a intentar minimizar a influencia que ten
14:02
on our lives.
332
830008
1883
nas nosas vidas.
14:03
Now, I find it helps to see life
333
831891
2818
Ben, penso que axuda ver a vida
14:06
as being like a book:
334
834709
1844
como un libro:
14:08
Just as a book is bounded by its covers,
335
836553
2468
Tal como un libro está
limitado polas cubertas,
14:11
by beginning and end,
336
839021
1277
por un comezo e un final,
14:12
so our lives are bounded by birth and death,
337
840298
3738
a nosa vida está limitada
polo nacemento e a morte,
14:16
and even though a book is
limited by beginning and end,
338
844036
3515
e aínda que un libro está
limitado por un comezo e un final,
14:19
it can encompass distant landscapes,
339
847551
2136
pode abarcar paraxes distantes,
14:21
exotic figures, fantastic adventures.
340
849687
3230
exóticas personaxes,
aventuras fantásticas.
14:24
And even though a book is
limited by beginning and end,
341
852917
3349
E aínda que un libro está
limitado por un comezo e un final,
14:28
the characters within it
342
856266
1823
as súas personaxes
14:30
know no horizons.
343
858089
2842
non coñecen horizontes.
14:32
They only know the moments
that make up their story,
344
860931
3157
Só coñecen os momentos
que conforman a súa historia,
14:36
even when the book is closed.
345
864088
2940
incluso cando o libro está pechado.
14:39
And so the characters of a book
346
867028
2136
Así, as personaxes dun libro
14:41
are not afraid of reaching the last page.
347
869164
3482
non teñen medo de acadar a última páxina,
14:44
Long John Silver is not afraid of you
348
872646
2278
Long John Silver non ten medo de que ti
14:46
finishing your copy of "Treasure Island."
349
874924
2835
remates de ler A illa do tesouro.
14:49
And so it should be with us.
350
877759
1700
Así deberiamos ser nós,
14:51
Imagine the book of your life,
351
879459
2144
imaxina o libro da túa vida,
14:53
its covers, its beginning and end,
and your birth and your death.
352
881603
2784
as cubertas, o comezo e o final,
o nacemento e a morte,
14:56
You can only know the moments in between,
353
884387
2177
Só podes coñecer os momentos intermedios,
14:58
the moments that make up your life.
354
886564
1935
os momentos que conforman a túa vida.
15:00
It makes no sense for you to fear
355
888499
1947
Non ten sentido que te asustes
15:02
what is outside of those covers,
356
890446
2090
do que hai fóra desas cubertas,
15:04
whether before your birth
357
892536
1470
xa sexa antes do teu nacemento
15:06
or after your death.
358
894006
1976
ou despois da túa morte.
15:07
And you needn't worry how long the book is,
359
895982
2529
E non precisas preocuparte
da lonxitude do libro,
15:10
or whether it's a comic strip or an epic.
360
898511
3473
de se é unha tira cómica ou unha epopea.
15:13
The only thing that matters
361
901984
1542
O único que importa,
15:15
is that you make it a good story.
362
903526
3498
é que fagas dela unha boa historia.
Grazas.
15:19
Thank you.
363

ABOUT THE SPEAKER
Stephen Cave - Philosopher
Philosopher Stephen Cave wants to know: Why is humanity so obsessed with living forever?

Why you should listen

Stephen Cave is a writer and philosopher who is obsessed with our obsession with immortality. In 2012 he published Immortality: The Quest to Live Forever and How It Drives Civilization, an inquiry into humanity's rather irrational resistance to the inevitability of death. Cave moves across time and history's major civilizations and religions to explore just what drives this instinct -- and what that means for the future. Cave writes for The Financial Times and contributes to The New York Times, The Guardian and Wired.
