  1. Thanks very much.
  2. I'm not going to beat Gregory with his
    saxophone for sure, but bear with me.
  3. This might be - no, it won't be remotely
    as interesting, as good or entertaining.
  4. Is there a real you?

  5. This might seem to you
    like a very odd question.
  6. Because, you might ask,
  7. how do we find the real you,
  8. how do you know what the real you is?
  9. And so forth.
  10. But the idea
    that there must be a real you,
  11. surely that's obvious.
  12. If there's anything real in the world,
    it's you.
  13. Well, I'm not quite sure.
  14. At least we have to understand
    a bit better what that means.
  15. Now certainly, I think there are
    lots of things in our culture around us
  16. which sort of reinforce the idea
  17. that for each one of us,
    we have a kind of a core, an essence.
  18. There is something about what it means
    to be you which defines you,
  19. and it's kind of permanent and unchanging.
  20. The most kind of crude way
    in which we have it,
  21. are things like horoscopes.
  22. You know, people are very wedded
    to these, actually.
  23. People put them on their Facebook profile
  24. as though they are meaningul,
  25. you even know
    your Chinese horoscope as well.
  26. There are also more scientific
    versions of this,
  27. all sorts of ways of profiling
    personality type,
  28. such as the Myers-Briggs tests,
    for example.
  29. I don't know if you've done those.
  30. A lot of companies
    use these for recruitment.
  31. You answer a lot of questions,
  32. and this is supposed to reveal
    something about your core personality.
  33. And of course, the popular fascination
    with this is enormous.
  34. In magazines like this, you'll see,
  35. in the bottom left corner,
    they'll advertise in virtually every issue
  36. some kind of personality thing.
  37. And if you pick up one of those magazines,
  38. it's hard to resist, isn't it?
  39. Doing the test to find
    what is your learning style,
  40. what is your loving style,
    or what is your working style?
  41. Are you this kind of person or that?
  42. So I think that we have
    a common-sense idea
  43. that there is a kind of core
    or essence of ourselves
  44. to be discovered.
  45. And that this is kind of a permanent truth
    about ourselves,
  46. something that's the same throughout life.
  47. Well, that's the idea I want to challenge.
  48. And I have to say now,
    I'll say it a bit later,
  49. but I'm not challenging this
    just because I'm weird,
  50. the challenge actually has a very,
    very long and distinguished history.
  51. Here's the common-sense idea.
  52. There is you.
  53. You are the individuals you are,
    and you have this kind of core.
  54. Now in your life, what happens
    is that you, of course,
  55. accumulate different experiences
    and so forth.
  56. So you have memories,
  57. and these memories
    help to create what you are.
  58. You have desires, maybe for a cookie,
  59. maybe for something
    that we don't want to talk about
  60. at 11 o'clock in the morning in a school.
  61. You will have beliefs.
  62. This is a number plate
    from someone in America.
  63. I don't know whether this number plate,
    which says "messiah 1,"
  64. indicates that the driver
    believes in the messiah,
  65. or that they are the messiah.
  66. Either way,
    they have beliefs about messiahs.
  67. We have knowledge.
  68. We have sensations
    and experiences as well.
  69. It's not just intellectual things.
  70. So this is kind of the common-sense model,
    I think,
  71. of what a person is.
  72. There is a person who has all the things
    that make up our life experiences.
  73. But the suggestion
    I want to put to you today
  74. is that there's something
    fundamentally wrong with this model.
  75. And I can show you what's wrong
    with one click.
  76. Which is there isn't actually a "you"
    at the heart of all these experiences.
  77. Strange thought?
    Well, maybe not.
  78. What is there, then?
  79. Well, clearly there are memories,
    desires, intentions, sensations,
  80. and so forth.
  81. But what happens is
    these things exist,
  82. and they're kind of all integrated,
  83. they're overlapped, they're connected
    in various different ways.
  84. They're connecting partly,
    and perhaps even mainly,
  85. because they all belong
    to one body and one brain.
  86. But there's also a narrative,
    a story we tell about ourselves,
  87. the experiences we have
    when we remember past things.
  88. We do things because of other things.
  89. So what we desire is partly
    a result of what we believe,
  90. and what we remember is also
    informing us what we know.
  91. And so really, there are all these things,
  92. like beliefs, desires,
    sensations, experiences,
  93. they're all related to each other,
  94. and that just is you.
  95. In some ways, it's a small difference
    from the common-sense understanding.
  96. In some ways, it's a massive one.
  97. It's the shift between
    thinking of yourself
  98. as a thing which has
    all the experiences of life,
  99. and thinking of yourself
    as simply that collection
  100. of all experiences in life.
  101. You are the sum of your parts.
  102. Now those parts are also physical parts,
    of course,
  103. brains, bodies and legs and things,
  104. but they aren't so important, actually.
  105. If you have a heart transplant,
    you're still the same person.
  106. If you have a memory transplant,
    are you the same person?
  107. If you have a belief transplant,
    would you be the same person?
  108. Now this idea, that what we are,
    the way to understand ourselves,
  109. is as not of some permanent being,
    which has experiences,
  110. but is kind of a collection
    of experiences,
  111. might strike you as kind of weird.
  112. But actually,
    I don't think it should be weird.
  113. In a way, it's common sense.
  114. Because I just invite you to think about,
    by comparison,
  115. think about pretty much anything else
    in the universe,
  116. maybe apart from the very
    most fundamental forces or powers.
  117. Let's take something like water.
  118. Now my science isn't very good.
  119. We might say something
    like water has two parts hydrogen
  120. and one parts oxygen, right?
  121. We all know that.
  122. I hope no one in this room
    thinks that what that means
  123. is there is a thing called water,
    and attached to it
  124. are hydrogen and oxygen atoms,
  125. and that's what water is.
  126. Of course we don't.
  127. We understand, very easily,
    very straightforwardly,
  128. that water is nothing more
  129. than the hydrogen and oxygen molecules
    suitably arranged.
  130. Everything else in the universe
    is the same.
  131. There's no mystery about my watch,
    for example.
  132. We say the watch has a face, and hands,
  133. and a mechanism and a battery,
  134. But what we really mean is,
  135. we don't think there is a thing
    called the watch
  136. to which we then attach all these bits.
  137. We understand very clearly
    that you get the parts of the watch,
  138. you put them together,
    and you create a watch.
  139. Now if everything else
    in the universe is like this,
  140. why are we different?
  141. Why think of ourselves
  142. as somehow not just being
    a collection of all our parts,
  143. but somehow being a separate,
    permanent entity which has those parts?
  144. Now this view is not particularly new,
  145. It has quite a long lineage.
  146. You find it in Buddhism,
  147. you find it in 17th,
    18th-century philosophy
  148. going through to the current day,
    people like Locke and Hume.
  149. But interestingly, it's also a view
  150. increasingly being heard
    reinforced by neuroscience.
  151. This is Paul Broks,
    he's a clinical neuropsychologist,
  152. and he says this:
  153. "We have a deep intuition
    that there is a core,
  154. an essence there,
    and it's hard to shake off,
  155. probably impossible to shake off,
    I suspect.
  156. But it's true that neuroscience shows
    that there is no centre in the brain
  157. where things do all come together."
  158. So when you look at the brain,
  159. and you look at how the brain
    makes possible a sense of self,
  160. you find that there isn't
    a central control spot in the brain.
  161. There is no kind of center
    where everything happens.
  162. There are lots of different processes
    in the brain,
  163. all of which operate, in a way,
    quite independently.
  164. But it's because of the way
    that they relate
  165. that we get this sense of self.
  166. The term I use in the book,
    I call it the ego trick.
  167. It's like a mechanical trick.
  168. It's not that we don't exist,
  169. it's just that the trick is
    to make us feel that inside of us
  170. is something more unified
    than is really there.
  171. Now you might think
    this is a worrying idea.
  172. You might think that if it's true,
  173. that for each one of us
    there is no abiding core of self,
  174. no permanent essence,
  175. does that mean that really,
    the self is an illusion?
  176. Does it mean that we really don't exist?
  177. There is no real you.
  178. Well, a lot of people actually
    do use this talk of illusion and so forth.
  179. These are three psychologists,
    Thomas Metzinger, Bruce Hood,
  180. Susan Blackmore,
  181. a lot of these people
    do talk the language of illusion,
  182. the self is an illusion, it's a fiction.
  183. But I don't think this is
    a very helpful way of looking at it.
  184. Go back to the watch.
  185. The watch isn't an illusion,
    because there is nothing to the watch
  186. other than a collection of its parts.
  187. In the same way,
    we're not illusions either.
  188. The fact that we are, in some ways,
    just this very, very complex collection,
  189. ordered collection of things,
  190. does not mean we're not real.
  191. I can give you a very
    sort of rough metaphor for this.
  192. Let's take something like a waterfall.
  193. These are the Iguazu Falls, in Argentina.
  194. Now if you take something like this,
  195. you can appreciate the fact
    that in lots of ways,
  196. there's nothing permanent about this.
  197. For one thing, it's always changing.
  198. The waters are always
    carving new channels.
  199. with changes in tides and the weather,
  200. some things dry up,
    new things are created.
  201. Of course the water
    that flows through the waterfall
  202. is different at every single instance.
  203. But it doesn't mean
    that the Iguazu Falls are an illusion.
  204. It doesn't mean it's not real.
  205. What it means is
    we have to understand what it is
  206. as something which has a history,
  207. has certain things that keep it together,
  208. but it's a process, it's fluid,
    it's forever changing.
  209. Now that, I think, is a model
    for understanding ourselves,
  210. and I think it's a liberating model.
  211. Because if you think that you have
    this fixed, permanent essence,
  212. which is always the same,
    throughout your life, no matter what,
  213. in a sense you're kind of trapped.
  214. You're born with an essence,
  215. that's what you are until you die,
  216. if you believe in an afterlife,
    maybe you continue.
  217. But if you think of yourself
    as being, in a way,
  218. not a thing as such,
    but a kind of a process,
  219. something that is changing,
  220. then I think that's quite liberating.
  221. Because unlike the the waterfalls,
  222. we actually have the capacity to channel
  223. the direction of our development
    for ourselves to a certain degree.
  224. Now we've got to be careful here, right?
  225. If you watch the X-Factor too much,
    you might buy into this idea
  226. that we can all be whatever we want to be.
  227. That's not true.
  228. I've heard some fantastic musicians
    this morning,
  229. and I am very confident
    that I could in no way be as good as them.
  230. I could practice hard and maybe be good,
  231. but I don't have
    that really natural ability.
  232. There are limits to what we can achieve.
  233. There are limits to
    what we can make of ourselves.
  234. But nevertheless, we do have this capacity
  235. to, in a sense, shape ourselves.
  236. The true self, as it were then,
  237. is not something that is just there
    for you to discover,
  238. you don't sort of look into your soul
    and find your true self.
  239. What you are partly doing, at least,
  240. is actually creating your true self.
  241. And this, I think, is very,
    very significant,
  242. particularly
    at this stage of life you're at.
  243. You'll be aware of the fact
  244. how much of you changed over recent years.
  245. If you have any videos of yourself,
    three or four years ago,
  246. you probably feel embarrassed
    because you don't recognize yourself.
  247. So I want to get that message over,
    that what we need to do
  248. is think about ourselves as things
    that we can shape,
  249. and channel and change.
  250. This is the Buddha, again:
  251. "Well-makers lead the water,
  252. fletchers bend the arrow,
  253. carpenters bend a log of wood,
  254. wise people fashion themselves."
  255. And that's the idea
    I want to leave you with,
  256. that your true self is not something
    that you will have to go searching for,
  257. as a mystery, and maybe never ever find.
  258. To the extent you have a true self,
  259. it's something that you in part discover,
  260. but in part create.
  261. and that, I think,
    is a liberating and exciting prospect.
  262. Thank you very much.
  263. (Applause)
