  4. 0:34hello and welcome tonight we're speaking
  5. 0:35about the philosophy of language with me
  6. 0:38is professor John surl Professor surl
  7. 0:40has been teaching at the University of
  8. 0:42California at Berkeley since
  9. 0:451959 Professor surl thank you for coming
  10. 0:47thanks for having me all right well
  11. 0:49you've been a professor at the
  12. 0:50University of California at Berkeley for
  13. 0:53how many years 50 I guess it's 53 years
  14. 0:56I came here in
  15. 0:581959 and uh it adds up I've been a
  16. 1:00full-time Professor here since then do
  17. 1:02you hold the oldtime record I think I do
  18. 1:05I don't you see in the old days people
  19. 1:07were forced to retire when they got to
  20. 1:08be 70 years old now they figured out
  21. 1:11that's unconstitutional a bunch of old
  22. 1:13people in the Supreme Court figured if
  23. 1:14you can't fire people because they're
  24. 1:16black or female you can't fire them
  25. 1:17because they're over the age of 70
  26. 1:19anyway I can keep going indefinitely so
  27. 1:21I as they can't force me to retire and
  28. 1:23I'm having too much fun teaching I'm not
  29. 1:25going to retire great you're working on
  30. 1:28three books right now yes I am right
  31. 1:30youve plowed a lot of original ground on
  32. 1:32the philosophy of language starting with
  33. 1:34speech acts yes that was my first
  34. 1:37book now another of your books many of
  35. 1:40your books deal with Consciousness and
  36. 1:42then the whole Mind Body problem quote
  37. 1:44yes well I got from language I thought
  38. 1:46well my theory of language really makes
  39. 1:49heavy use of the mind because I see
  40. 1:51talking as performing intentional gold
  41. 1:54directed speech acts and that means they
  42. 1:55got to have some mental content so I
  43. 1:57thought I got to pay my due someday and
  44. 1:59I'm going to write book about the mind
  45. 2:01and then I discovered there's a whole a
  46. 2:04a garbage pit of bad philosophical views
  47. 2:07going on about the mind and I started
  48. 2:08getting debates about them and that went
  49. 2:11on to a whole bunch of other books that
  50. 2:12I wrote about the mind and then I got
  51. 2:14interested in society and I've written
  52. 2:15some books about Society what's the
  53. 2:16nature of
  54. 2:18society the Mind Body problem it's not
  55. 2:20quite the same as the stomach digestion
  56. 2:22problem no it's not but it ought to be
  57. 2:25that is we have this we have two
  58. 2:27conflicting Traditions both of which are
  59. 2:29s of confusion one tradition says
  60. 2:33there's God the soul and immortality and
  61. 2:36they're not part of the physical world
  62. 2:38and there's another tradition that says
  63. 2:41science is materialistic and there's no
  64. 2:44place in science for the mind now I
  65. 2:46think both these Traditions are mistaken
  66. 2:48I I think the mind is just a function of
  67. 2:50the brain it's the mental processes are
  68. 2:53processes that are produced by brain
  69. 2:54processes and they exist in the brain so
  70. 2:57I like to make this boring analogy
  71. 2:58roughly speaking I the mind is to the
  72. 3:01brain as digestion is to the stomach
  73. 3:03it's just something that that happens
  74. 3:06and it happens by natural biological
  75. 3:08processes but we know all of those
  76. 3:12natural biological processes for the
  77. 3:14digestion in the stomach but we cannot
  78. 3:16find or locate the part of the brain
  79. 3:19that generates what we call
  80. 3:20Consciousness well we're getting closer
  81. 3:22to that uh I was in the president's
  82. 3:24decade of the brain in the 1990s and we
  83. 3:27didn't solve the problems but we got a
  84. 3:29lot closer we know a whole lot more
  85. 3:31about the brain than we did when I first
  86. 3:34got interested in these issues about 20
  87. 3:35or 30 years ago still you're right we
  88. 3:38don't know how exactly the brain causes
  89. 3:42Consciousness uh we know quite a lot
  90. 3:44about specific processes like how the
  91. 3:47visual signal is processed from the time
  92. 3:49the photons hit the retina until it goes
  93. 3:51through all the parts of the brain and
  94. 3:53gets into the cortex but how exactly do
  95. 3:55you get over the hump from neuron
  96. 3:57firings to Consciousness that's a fast
  97. 3:59any question and we don't know the
  98. 4:01solution to that at least not yet but
  99. 4:03we're Lots closer than we
  100. 4:05were it it's amazing to think that all
  101. 4:08of the various physical Sensations that
  102. 4:10we experience uh the taste of something
  103. 4:13or the the sight or the feel of it it's
  104. 4:15all neurons firing at different frequeny
  105. 4:17it is a stunning fact that the enormous
  106. 4:20variety The Incredible variety of our
  107. 4:22conscious life everything from having a
  108. 4:24stomach ache to I don't know pick your
  109. 4:26favorite feeling the enst of
  110. 4:27post-industrial man under late cap Capal
  111. 4:29ISM all of that is caused by variable
  112. 4:32rates of neuron firings relative to
  113. 4:35specific neuronal architectures that's
  114. 4:37an amazing fact but as far as we know
  115. 4:39that's how it
  116. 4:40works it seems that Neuroscience is is a
  117. 4:44field that's exciting all the sciences
  118. 4:46that the
  119. 4:47psychology uh uh sort of ends there and
  120. 4:51philosophy uh ends there and and um
  121. 4:54there's a lot of uh uh
  122. 4:57interdisciplinary um in the Sciences now
  123. 5:00that I mean outside of quantum mechanics
  124. 5:02and
  125. 5:03some cosmology some exciting areas of
  126. 5:06physics I think the most exciting area
  127. 5:08of the science right now is neuroscience
  128. 5:11because here is this incredibly complex
  129. 5:14mechanism and we don't know how it works
  130. 5:17but we're finding out how it works we're
  131. 5:19finding out how memories are laid down
  132. 5:21in your brain we're even finding out why
  133. 5:23alcohol makes you drunk I so we've got
  134. 5:26all of this exciting areas of research
  135. 5:28going on and we are making a lot of
  136. 5:30progress however as I said the big Gulf
  137. 5:33and we haven't solved it yet is how
  138. 5:35exactly do neuron neuron neuronal
  139. 5:37processes cause Consciousness that's a
  140. 5:40beautiful question um and I hope it's
  141. 5:42solved in my lifetime but um excuse me
  142. 5:45may take longer do you um do you think
  143. 5:49it's a fair statement to call the brain
  144. 5:51the most complicated structure in the
  145. 5:52known universe well people always say
  146. 5:55that but you see complexity always is
  147. 5:58always relative to the the assignment of
  148. 6:00some kind of criteria for judging
  149. 6:03complexity is the Amazon
  150. 6:05jungle complex that's not really a fully
  151. 6:08meaningful question and I think the the
  152. 6:11problem with invoking complexity the
  153. 6:12brain is complex but for all we know the
  154. 6:15mechanisms by which Consciousness is
  155. 6:18produced in simple organisms may be
  156. 6:21simple mechanisms and it may be that
  157. 6:23that's the key to understanding human
  158. 6:25consciousness so if you think of DNA and
  159. 6:28how it produces the enormous complex
  160. 6:30variety of human phenotypes yes they are
  161. 6:33incredibly complex and the processes are
  162. 6:35complex all the same the structure of
  163. 6:38DNA is fairly simple and easily
  164. 6:41understandable so there there's a sort
  165. 6:43of fature of this discussion where
  166. 6:45people invoke complexity as kind of a
  167. 6:47magic term they get dazzled by the
  168. 6:49incredible complexity of the brain it is
  169. 6:51complex but we it doesn't follow from
  170. 6:53that that the mechanisms by which
  171. 6:55Consciousness are is produced uh are
  172. 6:58themselves extremely comp Lex mechanisms
  173. 7:00and there for all we know that lots of
  174. 7:02simple organisms may be conscious and if
  175. 7:05so their Consciousness may be produced
  176. 7:07by fairly simple
  177. 7:08mechanisms Chomsky talked about discret
  178. 7:11Infinity yeah um and uh you see that in
  179. 7:16language you see that from a very simple
  180. 7:18alphabet you get the amazing you get
  181. 7:20Shakespeare from the morse code you get
  182. 7:22Shakespeare yes um well chsky is right
  183. 7:25about that that we have a discrete set
  184. 7:28and a finite set of devices words
  185. 7:31morphemes and the and the Capa and rules
  186. 7:34for combining them and that gives us an
  187. 7:37infinite capacity and a capacity to
  188. 7:39generate an infinite number of different
  189. 7:42sentences and that's an extraordinary
  190. 7:44property of human languages there's no
  191. 7:46limit to the number of new things that
  192. 7:48we can say would you say that that
  193. 7:50property is unique to language or do you
  194. 7:52see it in biology well you see it in the
  195. 7:54DNA with a very limited number of base
  196. 7:56pairs you have all of the incredible the
  197. 7:58capacity for infinite generative
  198. 8:00capacity is not confined to language you
  199. 8:02can do it with with DNA or all all sorts
  200. 8:04of other combinatorial mechanisms but
  201. 8:06what's interesting about um language is
  202. 8:09not just that you have this infinite
  203. 8:11capacity I mean you could do that with
  204. 8:13infinite capacity 1 2 3 4 five but
  205. 8:16you've got compositionality that is to
  206. 8:18say in addition to the generative
  207. 8:21feature you've got the fact that you can
  208. 8:23figure out the meaning of the sentence
  209. 8:25just by knowing the meanings of the
  210. 8:27words and how they're combined in the
  211. 8:28sentence so I think the generativity is
  212. 8:32exciting but what makes it exciting is
  213. 8:34it's combined with composition you
  214. 8:37understand the meaning of sentences
  215. 8:38you've never heard before just because
  216. 8:40you know the meanings of the parts and
  217. 8:42how they're composed how they're
  218. 8:43combined in the sentence and intent and
  219. 8:46the well you can you see they have to be
  220. 8:48produced with an intent and what you do
  221. 8:51when you understand the sense is you
  222. 8:53understand the intention behind its
  223. 8:55utterance so this is the remarkable
  224. 8:57capacity about human language not only
  225. 8:59is we can um convey our intentional
  226. 9:03meanings to other people but we can have
  227. 9:06all kinds of intentional meanings all
  228. 9:08kinds of thought contents that we
  229. 9:09couldn't possibly have without language
  230. 9:11so language doesn't just describe a
  231. 9:14pre-existing State of Affairs a
  232. 9:17pre-existing set of thoughts but it
  233. 9:19enables us to have thoughts that we
  234. 9:21couldn't possibly have without language
  235. 9:23it's like stepping stones to cognition
  236. 9:25well it's more than just stepping stones
  237. 9:27it is a it is forms of cognition that
  238. 9:31are made possible by language that
  239. 9:33wouldn't be possible without it so for
  240. 9:35example you can't do mathematics if you
  241. 9:38don't have a language and indeed now I
  242. 9:40introduce another element that's writing
  243. 9:41you really can't do complex mathematics
  244. 9:44unless you have a written language and
  245. 9:46now just to add something to that much
  246. 9:49of our social reality of the reality of
  247. 9:52money and property and government and
  248. 9:55marriage and universities and cocktail
  249. 9:57parties and television programs that
  250. 9:59created by language which writing yeah
  251. 10:02well and and well especially written
  252. 10:04language you can have simple forms of
  253. 10:06institutional reality you can have uh
  254. 10:08forms of private property and and simple
  255. 10:11U governmental relations but to have
  256. 10:14complex forms of the kind that we have I
  257. 10:16mean think of our pres presidential
  258. 10:18election you cannot have that without
  259. 10:20written language the the phenomena are
  260. 10:22too complex to be conveyed just in an
  261. 10:25oral culture lasting commitments
  262. 10:28marriage yes
  263. 10:30now here's something that language gives
  264. 10:31us that no other animal has we have
  265. 10:34forms of commitment that are carried by
  266. 10:37language that pre-linguistic animals
  267. 10:40cannot have so for example a guy asked
  268. 10:43me to come to downtown Berkeley I and
  269. 10:46have a television talk and that gives me
  270. 10:49a reason for doing it which is
  271. 10:51independent of my other inclinations see
  272. 10:54my dog is very intelligent but he cannot
  273. 10:56make promises he can't undertake those
  274. 10:59sorts of commitments he cannot reason
  275. 11:01with obligations and operate with with
  276. 11:04commitments of various kinds so we've
  277. 11:06got not just infinite generative
  278. 11:08capacity and creative capacity for
  279. 11:10creating thought but we create a social
  280. 11:13reality and we create a set of binding
  281. 11:17relationships among human beings so I
  282. 11:20think in a way language is the glue that
  283. 11:22holds human civilization together
  284. 11:24because it creates all of these bonds it
  285. 11:27creates all of these desire independent
  286. 11:29reasons for actions like obligations
  287. 11:31commitments requirements duties and all
  288. 11:33the rest of
  289. 11:35it with all this power of language there
  290. 11:38comes a danger too of becoming too
  291. 11:41abstract yeah not keeping your feet on
  292. 11:43the ground referring to referring to
  293. 11:45referring well that's right um and the
  294. 11:48problem with um language I like your
  295. 11:50metaphor the feet on the ground because
  296. 11:52it's very important to remember to stay
  297. 11:55close to the real world and in my
  298. 11:57discipline philosophy there's always a
  299. 12:00temptation to go off into outer space
  300. 12:03into hot air and in fact there are
  301. 12:05various movements that make a career out
  302. 12:07of that there was something you're
  303. 12:09probably old enough to remember this but
  304. 12:10there was something called
  305. 12:12postmodernism uh and there there was a
  306. 12:14lot of hot air where they said well
  307. 12:16maybe all of reality is created by
  308. 12:18language and everything is a text and so
  309. 12:20on no language has to stay close to
  310. 12:22reality I if it is to be fully
  311. 12:25meaningful and if its meaning is to be
  312. 12:27comprehensible but and this is what
  313. 12:28makes it fascinating much of the reality
  314. 12:31that language has to stay close to is
  315. 12:34itself created by language so the
  316. 12:36reality of government the fact the
  317. 12:39reality of the election that we're
  318. 12:41having the reality of the candidacy and
  319. 12:43the voting all of those are linguistic
  320. 12:46phenomena they're created by language
  321. 12:48and yet in creating them in creating for
  322. 12:51example the office of the presidency and
  323. 12:54making a guy president of the United
  324. 12:55States we use semantics to create a
  325. 12:59power are set of powers that go beyond
  326. 13:01semantics so this again a remarkable
  327. 13:04property about language is that it
  328. 13:06serves to describe reality and we have
  329. 13:09to stay close to the non-linguistic
  330. 13:12reality that it describes but it also
  331. 13:14creates a reality the reality of instit
  332. 13:17what I call institutional facts like
  333. 13:19money and government and private
  334. 13:20property it creates a reality which we
  335. 13:23can then go on to describe in objective
  336. 13:27terms what about the danger in our
  337. 13:29social reality of the abstraction of
  338. 13:31money and the way that it runs people
  339. 13:34and you know it seems to be running the
  340. 13:36world and it's like an abstraction
  341. 13:38that's gotten away from us uh there are
  342. 13:39lots of dangers we can't control one is
  343. 13:43the powers that we create with these
  344. 13:45cognitive mechanisms can run out of
  345. 13:48control and one of the fascinating
  346. 13:51things that happened in the past
  347. 13:54decade was uh that the all my economists
  348. 13:57of friends have told me we'd never have
  349. 13:58another economic crisis like the 1930s
  350. 14:01because we know too much economics well
  351. 14:03it turns out we didn't know so much it
  352. 14:05got out of hand and of course A lot of
  353. 14:07people are now saying well I predicted
  354. 14:08that this was going to happen well of
  355. 14:10course I predicted that there was a
  356. 14:12housing bubble anybody could see that
  357. 14:13even in the city of Burkley but nobody
  358. 14:16quite was able to foresee what in fact
  359. 14:19happened or or in fact get a a correct
  360. 14:23solution to the problems so um I I don't
  361. 14:27want to give the idea that these
  362. 14:29institutional facts that we create with
  363. 14:32language are all sweetness and light on
  364. 14:34the contrary you can just as you can
  365. 14:36create Democrats and Republicans you can
  366. 14:38create Communists and fascists you can
  367. 14:40create all kinds of evil mechanisms
  368. 14:43using the linguistic devices so the our
  369. 14:46capacity to use language in all sorts of
  370. 14:49creative ways doesn't yet give us the
  371. 14:52moral constraints those have to be added
  372. 14:55to the to the power of language we have
  373. 14:58to see how to constrain our use of
  374. 15:01language with morality and intelligence
  375. 15:03so it doesn't get out of hand do you
  376. 15:06think that it's a technology that we
  377. 15:08fully understand enough to do the
  378. 15:10technology of language yes no I don't
  379. 15:12think it is no I I think we're still
  380. 15:14working on it um but we have made a lot
  381. 15:16of progress now I I think that some of
  382. 15:19that progress is going in the wrong
  383. 15:21direction I mean this isn't the time to
  384. 15:23go into a discussion of chomsky's
  385. 15:25linguistics but I think he neglects the
  386. 15:27fact that sentences are used to perform
  387. 15:31speech acts and a lot of the syntactical
  388. 15:33facts about what's what goes in a
  389. 15:35sentence and what doesn't go those can
  390. 15:37only be explained if you understand how
  391. 15:39it's used so we still don't have an
  392. 15:41adequate theory of the relation of
  393. 15:44structure and function in natural
  394. 15:46languages there are lots of theories
  395. 15:48about structure and I have tried to
  396. 15:50develop theories about function but what
  397. 15:52I would like to see and I'm not enough
  398. 15:55of a syn tactician to do this myself is
  399. 15:58a serious analysis of the relationship
  400. 16:00between structure and function I think
  401. 16:02that would be a fascinating study see
  402. 16:04here's the Paradox of of Chomsky admir
  403. 16:07his work enormously but he's had now
  404. 16:09more than 50 years and there are no set
  405. 16:13of results that competence that
  406. 16:15competent linguists are prepared to
  407. 16:16agree on it's not like other Sciences
  408. 16:19see in biology we've got results that
  409. 16:21competent biologists agree on that's not
  410. 16:23really true in linguistics that's still
  411. 16:25divided into these Waring factions do
  412. 16:28you agree with ch that language is a
  413. 16:30facility that we innately have like
  414. 16:32Vision yes I I think that's right that
  415. 16:35we have this ability but that doesn't
  416. 16:37really say very much there's a friend of
  417. 16:38mine Dan Everett who uh found a language
  418. 16:41in the Amazon basin where he went and
  419. 16:44lived with those people for 30 years and
  420. 16:46he found a language there that doesn't
  421. 16:47follow chomsky's rules Chomsky says that
  422. 16:50all language has to have recursive rules
  423. 16:53and he says I don't know who's right in
  424. 16:55this but certainly he raises an
  425. 16:56interesting possibility that the pahad
  426. 16:59the tribe he studies the Amazon basin
  427. 17:01they don't have these rules that have
  428. 17:02these mathematical properties that
  429. 17:04Chomsky described they can't make
  430. 17:06relative clauses they can't say I met
  431. 17:08the man who knew my mother they have to
  432. 17:10say I met the man the man knew my mother
  433. 17:12but they can't make a relative clause
  434. 17:14and that's just the fact about their
  435. 17:16language is that they don't have
  436. 17:17recursion I don't see why that's
  437. 17:19impossible though it was though it's a
  438. 17:21counterexample to chomsky's
  439. 17:24views I recall you mentioning once U
  440. 17:27something about uh the sort of dualism
  441. 17:30that that people tend to to lapse into
  442. 17:32when they're thinking you were
  443. 17:34describing um
  444. 17:36your uh theories about uh one
  445. 17:39philosopher I think it was um wienstein
  446. 17:41wienstein
  447. 17:43yeah um you you liked his early work um
  448. 17:47but you thought that it needed some some
  449. 17:50amending or those ideas were incomplete
  450. 17:53and someone another philosopher said
  451. 17:54well then you must like the second work
  452. 17:57and you said no I I I I just think the
  453. 17:59first work needs uh uh those ideas need
  454. 18:02some developing yeah and I it's just
  455. 18:04it's something that that I see all the
  456. 18:06time around me is it it seems like um
  457. 18:09this sort of a a binary dualism where
  458. 18:11it's like a an excuse not to think it's
  459. 18:14like if it's not communism it's
  460. 18:15capitalism or if it's not a it's B you
  461. 18:17know or if it's not zero it's one um do
  462. 18:20you have any thoughts on well I I I
  463. 18:22think in fact there are valuable parts
  464. 18:24of both early wienstein and later vien
  465. 18:27Stein my own approach to langu is really
  466. 18:30different from either of those but still
  467. 18:32vien Stein was one of the great
  468. 18:33philosophers of the 20th century made an
  469. 18:35enormous contradiction the point you're
  470. 18:38making now is that we do tend to think
  471. 18:40in binary categories good guys and bad
  472. 18:43guys uh the people were for and the
  473. 18:46people were against and of course real
  474. 18:48life is much too complicated to make
  475. 18:50those categories and I think part of
  476. 18:52what we try to teach people in education
  477. 18:55particularly in education and philosophy
  478. 18:57is to get a richer set of categories and
  479. 19:00one indeed one of the things that you
  480. 19:02get of an education which isn't really
  481. 19:05officially a very well marked but it
  482. 19:08certainly is the mark of an educated
  483. 19:10person and that is the ability to make
  484. 19:13subtle
  485. 19:14discriminations so it is just good and
  486. 19:16bad but there are all kinds of nice ways
  487. 19:20of describing what exactly is good about
  488. 19:22it and what is bad about it there's a
  489. 19:25kind of manism that pervades popular
  490. 19:27culture and we're all
  491. 19:29victims of it we think well the guys on
  492. 19:31our side those are the good guys and the
  493. 19:33guys on the other side those are really
  494. 19:35the bad guys yeah and this really comes
  495. 19:38out especially strong in elections The
  496. 19:41Secret of successful democracies is it
  497. 19:44really shouldn't make too much
  498. 19:46difference who gets elected I think life
  499. 19:49will I mean I happen to be for one
  500. 19:51candidate and not the other but I
  501. 19:52recognize that for the most part Life
  502. 19:54Will Go On even if the other guys uh get
  503. 19:58elected
  504. 19:59whereas the your real dichotomy people
  505. 20:02think no this would be the end of
  506. 20:04civilization as we know it if the bad
  507. 20:06guys get elected in the case of
  508. 20:07democracies that's not true successful
  509. 20:10democracies have to allow for genuine
  510. 20:13Alternatives coming to power and the the
  511. 20:16reason for that is that the outcome of
  512. 20:18the election doesn't actually settle the
  513. 20:21major questions who's going to live and
  514. 20:22who's going to die who's going to be
  515. 20:24rich and who's going to be poor you
  516. 20:26don't want those issues settled at
  517. 20:27elections do you think that um we'd be
  518. 20:30better served with the proportional
  519. 20:33representation and multiple parties and
  520. 20:35now we we're getting off the topic
  521. 20:37you're getting off the topic but but uh
  522. 20:39no I don't I think what you want is a
  523. 20:41kind of stability and in particular in
  524. 20:43America with this enormous complexity
  525. 20:46and pluralism and all these different
  526. 20:48factions and all these different
  527. 20:49traditions and cultures it's very
  528. 20:52important that you not just divide up
  529. 20:55the government of the country in a whole
  530. 20:56lot of quarreling factions and the fact
  531. 20:59that the executive has to be controlled
  532. 21:01by one party or another forces us to
  533. 21:03have a two-party system it forces all
  534. 21:06sorts of diverse groups to come together
  535. 21:08and I think that's part of the
  536. 21:09unconscious Genius of the American
  537. 21:11Constitution is it forces us uh to a
  538. 21:14kind of agreement that you wouldn't get
  539. 21:16in a in a a plural system in a well in a
  540. 21:21constitu in a a parliamentary type
  541. 21:25system you know to go back to pany ism
  542. 21:28for a minute you you mentioned that you
  543. 21:31could see where it's attractive to
  544. 21:32people yeah um I think of the many
  545. 21:35indigenous people that that felt like
  546. 21:37there was Spirit everywhere and that was
  547. 21:39was well let me tell you exactly what's
  548. 21:41wrong with it pans psychism is the view
  549. 21:43that everything is conscious
  550. 21:46Consciousness is everywhere I'm
  551. 21:48reviewing a book for the New York Review
  552. 21:50where the author says the universe is
  553. 21:53suffused with Consciousness now that is
  554. 21:56hot air and I can tell you why why
  555. 21:58people are tempted to it and why it's uh
  556. 22:02nonsense they're tempted to it because
  557. 22:04as I said earlier we don't know how the
  558. 22:06brain creates Consciousness and it's
  559. 22:08tempting to think well maybe it doesn't
  560. 22:10create Consciousness maybe Consciousness
  561. 22:12is there everywhere like gravity it just
  562. 22:14everywhere is uh pervaded with
  563. 22:16Consciousness and then we have little
  564. 22:18Islands or little pools of Consciousness
  565. 22:21in our heads but really Consciousness is
  566. 22:24everywhere now what's wrong without the
  567. 22:25proof of that isn't there a leap of
  568. 22:26logic on your part as well yeah well the
  569. 22:29the let me tell you what's incoherent
  570. 22:31about that view Consciousness comes in
  571. 22:35units my Consciousness is not the same
  572. 22:38as your Consciousness and they're not
  573. 22:40like adjoining puddles of mud that kind
  574. 22:42of leak into each other no there's a
  575. 22:44place where my Consciousness ends and
  576. 22:46yours begins and the pro all
  577. 22:49Consciousness comes in units now the
  578. 22:50problem with pan psychism is they can't
  579. 22:52say what the units are see I reviewed a
  580. 22:54guy who said well maybe thermostats are
  581. 22:56conscious why the thermostat why not
  582. 22:58each screw in the thermostat why not the
  583. 23:01building why not the whole heating
  584. 23:02system why not the whole city is that
  585. 23:04chers and if you say it was in fact yeah
  586. 23:07if but if you then say
  587. 23:09well um uh then all of these are
  588. 23:13conscious then what's the relationship
  589. 23:15between their Consciousness you see if
  590. 23:17you say my brain is clearly conscious
  591. 23:19but suppose you say but my so is my
  592. 23:20thumb and my fingernail and each
  593. 23:22molecule in my stomach what's the
  594. 23:23relation between those Consciousness and
  595. 23:26the consciousness of my brain so the Inc
  596. 23:28cerence of psychism can be stated in one
  597. 23:31sentence Consciousness comes in units
  598. 23:35and the panus cannot tell us what the
  599. 23:37units
  600. 23:39are you know on a spiritual level I
  601. 23:42remember reading a philosopher a couple
  602. 23:45different philosophers talking about the
  603. 23:47devel long development of sentience and
  604. 23:49and our language ability and and saying
  605. 23:52that that that this is when Nature
  606. 23:54became aware of itself because it now
  607. 23:57had created a creature that
  608. 24:00could understand the existence of Nature
  609. 24:02and talk about it and yeah and things
  610. 24:04like that and and my reaction to that
  611. 24:08was that it seemed uh uh some
  612. 24:11anthropomorphic yes it does you know I
  613. 24:13don't think that that's that nature
  614. 24:15became aware of itself when we became
  615. 24:17fully Cent most Consciousness in the
  616. 24:19universe is not self-aware most
  617. 24:21conscious in the universe is in animals
  618. 24:23or fish or birds that are not busy
  619. 24:27reflecting on thems elves their
  620. 24:29Consciousness functions biologically to
  621. 24:31assist in their survival but human
  622. 24:34consciousness which allows for the
  623. 24:36consciousness of Consciousness that is
  624. 24:38allows us to for for us to become
  625. 24:41conscious of our own conscious States
  626. 24:42and reflect on them and indeed to
  627. 24:44reflect on our reflecting on those
  628. 24:46conscious States as you and I are now
  629. 24:47doing I doubt very much that that goes
  630. 24:50very far down the philogenetic scale as
  631. 24:52it happens I'm a dog lover uh and I have
  632. 24:55a sequence of wonderful dogs the my
  633. 24:57favorite is the bernes mountain dog now
  634. 24:59these are intelligent dogs but I know
  635. 25:02they're not busy reflecting on this
  636. 25:05nature of their own introspective
  637. 25:07capacities they're mostly thinking about
  638. 25:09the cats they're going to chase and the
  639. 25:10bones that they're going to eat and they
  640. 25:12don't have the the time or the capacity
  641. 25:15to reflect on reflection they're not
  642. 25:17thinking about what a good bone it was
  643. 25:19yesterday well I maybe they're thinking
  644. 25:21about that I hope so but they do not
  645. 25:23have this remarkable capacity that human
  646. 25:25consciousness have and I think most of
  647. 25:27it we couldn't have without language
  648. 25:28to have these second and third and
  649. 25:30fourth level Consciousness where you
  650. 25:32have something that refers to referring
  651. 25:34and refers to referring to referring and
  652. 25:36that's extremely sophisticated it's not
  653. 25:38a feature of Consciousness in
  654. 25:40general well Professor surl we have a
  655. 25:42minute left um would you like to talk
  656. 25:45about what you're working on now your B
  657. 25:46yes I'm writing three books and the one
  658. 25:48I was working on today which I think is
  659. 25:50very exciting is
  660. 25:52perception I and if you know anything
  661. 25:54about the history of philosophy you know
  662. 25:56that the uh subject of perception is a
  663. 25:59horrendous mess mostly because a mistake
  664. 26:01made in the 17th century that says well
  665. 26:03you never really perceive the real world
  666. 26:06you only perceive your own experiences
  667. 26:09and then you have to ask how do you get
  668. 26:12from your experiences that you do
  669. 26:13perceive to the real world that you
  670. 26:15don't perceive is that decart or well
  671. 26:17that's decart and lock and then the
  672. 26:20question was rejected by Barkley and
  673. 26:22whom said well really the real world
  674. 26:23just is your experiences and that's
  675. 26:25another disaster so what we have to do I
  676. 26:28mean the perception is exciting because
  677. 26:30we want to be able to explain how our
  678. 26:32perceptual apparatus is conscious and
  679. 26:35consists of these conscious States but
  680. 26:37at the same time it gives us direct
  681. 26:39presentation of objects and states of
  682. 26:40Affairs in the world that's what I'm
  683. 26:42working on now two other books one on
  684. 26:44language and another one on philosophy
  685. 26:46in general I thought I'd write a general
  686. 26:48book about how to do philosophy good
  687. 26:51well Professor surl thank you so much
  688. 26:52for taking time out of your schedule to
  689. 26:54come talk to us well thank you very much
  690. 26:55for having me all right and thank you
  691. 26:58for watching good night
