that we're conscious. + +356 +00:15:13,320 --> 00:15:17,070 +These are all activities, +experiences in consciousness. + +357 +00:15:17,070 --> 00:15:19,713 +And if you define life as +a series of experiences, + +358 +00:15:19,713 --> 00:15:22,260 +then what we would say +is that an experience + +359 +00:15:22,260 --> 00:15:24,420 +is consciousness plus an object. + +360 +00:15:24,420 --> 00:15:27,771 +You are aware and then +you're aware of something. + +361 +00:15:27,771 --> 00:15:29,291 +- Right. +- And the things + +362 +00:15:29,291 --> 00:15:30,540 +that we're aware of, they keep changing. + +363 +00:15:30,540 --> 00:15:32,700 +So we have a series of experiences. + +364 +00:15:32,700 --> 00:15:35,070 +And consciousness plus +object one is one experience. + +365 +00:15:35,070 --> 00:15:36,240 +Consciousness plus object two + +366 +00:15:36,240 --> 00:15:37,647 +is another experience and so on. + +367 +00:15:37,647 --> 00:15:39,483 +And the consciousness is constant. + +368 +00:15:40,410 --> 00:15:44,130 +In Western thought the one +who came closest to this, + +369 +00:15:44,130 --> 00:15:47,280 +I would say, was the philosopher, +mathematician, scientist, + +370 +00:15:47,280 --> 00:15:52,210 +Descartes, who about 300 +years ago, set out to find out + +371 +00:15:53,220 --> 00:15:56,130 +an absolute certain basis for knowledge. + +372 +00:15:56,130 --> 00:15:59,580 +And he questioned whatever +could be questioned, doubted, + +373 +00:15:59,580 --> 00:16:02,610 +you could doubt, but he +found that your own existence + +374 +00:16:02,610 --> 00:16:03,460 +can't be doubted. + +375 +00:16:04,500 --> 00:16:06,690 +"I think, therefore I exist." + +376 +00:16:06,690 --> 00:16:08,610 +Vedanta would say that, exactly, + +377 +00:16:08,610 --> 00:16:11,310 +but you need to go one step further. + +378 +00:16:11,310 --> 00:16:13,170 +Even when I don't think, + +379 +00:16:13,170 --> 00:16:14,790 +I'm still aware of not thinking. + +380 +00:16:14,790 --> 00:16:15,990 +- Hmm. +- So- + +381 +00:16:16,920 --> 00:16:17,823 +- Yeah, that's a- + +382 +00:16:17,823 --> 00:16:20,190 +- Consciousness is primary. + +383 +00:16:20,190 --> 00:16:21,990 +Either thinking or not thinking, seeing. + +384 +00:16:21,990 --> 00:16:24,870 +I think that's what Descartes +was probably driving at. + +385 +00:16:24,870 --> 00:16:26,670 +In Descartes "Meditations", + +386 +00:16:26,670 --> 00:16:30,060 +there's a very poignant +place where he says, + +387 +00:16:30,060 --> 00:16:35,060 +"How strange it is that +whatever I know in this world, + +388 +00:16:35,700 --> 00:16:36,570 +I can doubt it. + +389 +00:16:36,570 --> 00:16:38,370 +I'm not sure of it. + +390 +00:16:38,370 --> 00:16:39,210 +We can doubt any of this exists." + +391 +00:16:39,210 --> 00:16:42,210 +It could be in the Matrix, +you could be dreaming. + +392 +00:16:42,210 --> 00:16:45,750 +But what I'm absolutely +sure of my own existence, + +393 +00:16:45,750 --> 00:16:49,020 +I don't know anything about +it, that consciousness. + +394 +00:16:49,020 --> 00:16:50,670 +- Do you think anything about + +395 +00:16:50,670 --> 00:16:53,130 +the different approaches +to understanding the world + +396 +00:16:53,130 --> 00:16:54,390 +and understanding consciousness, + +397 +00:16:54,390 --> 00:16:57,150 +say the spiritual and the +materialist approaches, + +398 +00:16:57,150 --> 00:17:00,570 +that they necessarily lead +to different conclusions + +399 +00:17:00,570 --> 00:17:03,150 +about meaning and purpose? + +400 +00:17:03,150 --> 00:17:05,700 +- I am a conscious being, +first and foremost. + +401 +00:17:05,700 --> 00:17:09,599 +Before even I am a body or a human being, + +402 +00:17:09,599 --> 00:17:11,460 +I'm a conscious being first. + +403 +00:17:11,460 --> 00:17:15,213 +And if that consciousness +itself is denied, + +404 +00:17:16,410 --> 00:17:20,790 +as an illusion or as nothing +but activities in matter, + +405 +00:17:20,790 --> 00:17:23,160 +in your living in the brain, + +406 +00:17:23,160 --> 00:17:26,369 +in that case, the things which +consciousness uniquely does, + +407 +00:17:26,369 --> 00:17:29,580 +like meaning and purpose, +they will also be denied. + +408 +00:17:29,580 --> 00:17:31,320 +They will also be reduced to either matter + +409 +00:17:31,320 --> 00:17:33,210 +or be dismissed as an illusion. + +410 +00:17:33,210 --> 00:17:36,000 +You'll inevitably have a worldview + +411 +00:17:36,000 --> 00:17:40,410 +which is devoid of meaning, of purpose. + +412 +00:17:40,410 --> 00:17:41,700 +So now we have this + +413 +00:17:41,700 --> 00:17:45,303 +profoundly disconnected +culture in the world today. + +414 +00:17:46,800 --> 00:17:50,700 +There is science, hardcore science, + +415 +00:17:50,700 --> 00:17:54,933 +and which claims absolute +possession of truth. + +416 +00:17:55,890 --> 00:17:59,850 +And there is religion, humanities, + +417 +00:17:59,850 --> 00:18:02,550 +all of which science would +say is sort of derivative. + +418 +00:18:02,550 --> 00:18:07,110 +You know that reality is +matter, space, time, energy + +419 +00:18:07,110 --> 00:18:09,360 +and from that life has evolved. + +420 +00:18:09,360 --> 00:18:10,710 +And then life sort of comes up + +421 +00:18:10,710 --> 00:18:15,210 +with these little illusions +of purpose, meaning, + +422 +00:18:15,210 --> 00:18:17,583 +value, beauty, goodness. + +423 +00:18:18,780 --> 00:18:21,180 +I think one interesting place is this, + +424 +00:18:21,180 --> 00:18:25,713 +where right now with ChatGPT +and everything with the AI, + +425 +00:18:26,880 --> 00:18:29,310 +notice something very +interesting is happening. + +426 +00:18:29,310 --> 00:18:31,680 +Whatever we human beings are capable of + +427 +00:18:31,680 --> 00:18:35,400 +and we thought our highest +capacities are like intelligence, + +428 +00:18:35,400 --> 00:18:38,490 +like memory or like creativity, +like decision-making. + +429 +00:18:38,490 --> 00:18:40,500 +Now these machines, AI-powered machines + +430 +00:18:40,500 --> 00:18:43,720 +are capable of doing all +of that except one thing + +431 +00:18:44,610 --> 00:18:47,130 +and that one thing is +they're not conscious. + +432 +00:18:47,130 --> 00:18:50,430 +And if you say that, all right, +make the machines conscious, + +433 +00:18:50,430 --> 00:18:52,380 +they wouldn't know where to begin. + +434 +00:18:52,380 --> 00:18:54,837 +That's why they're asking +what is consciousness + +435 +00:18:54,837 --> 00:18:58,230 +and how can you know artificial programs, + +436 +00:18:58,230 --> 00:18:59,550 +machines become conscious. + +437 +00:18:59,550 --> 00:19:00,550 +That's a huge issue. + +438 +00:19:02,610 --> 00:19:06,480 +- So some people say, "Well, +I was typing with the chatbot + +439 +00:19:06,480 --> 00:19:07,950 +and I asked if it was conscious- + +440 +00:19:07,950 --> 00:19:08,783 +- Yes. +- And it said + +441 +00:19:08,783 --> 00:19:09,636 +it was conscious. + +442 +00:19:09,636 --> 00:19:10,469 +So therefore it's conscious." + +443 +00:19:10,469 --> 00:19:11,302 +- Right. + +444 +00:19:11,302 --> 00:19:13,530 +- And you're like, "Okay by the way, + +445 +00:19:13,530 --> 00:19:15,330 +here I am, I sit here as a +human being in front of you, + +446 +00:19:15,330 --> 00:19:17,080 +I tell you I am God." + +447 +00:19:18,450 --> 00:19:19,770 +Okay? Right? + +448 +00:19:19,770 --> 00:19:21,510 +I mean like that doesn't, + +449 +00:19:21,510 --> 00:19:25,197 +you know there's more to +it then a reply like that. + +450 +00:19:25,197 --> 00:19:27,270 +- There's some competing claims. + +451 +00:19:27,270 --> 00:19:28,290 +- Yes. +- We'll have to sort that out. + +452 +00:19:28,290 --> 00:19:29,460 +- Yes. + +453 +00:19:29,460 --> 00:19:31,230 +- Reid Hoffman is one of +the world's best known + +454 +00:19:31,230 --> 00:19:33,420 +tech entrepreneurs and investors. + +455 +00:19:33,420 --> 00:19:34,770 +Perhaps best known for his role + +456 +00:19:34,770 --> 00:19:36,840 +in helping to co-found LinkedIn, + +457 +00:19:36,840 --> 00:19:38,220 +he's also an accomplished writer + +458 +00:19:38,220 --> 00:19:39,620 +and a student of philosophy. + +459 +00:19:40,560 --> 00:19:43,260 +Reid was an early investor +and advisor to OpenAI, + +460 +00:19:43,260 --> 00:19:45,810 +the startup responsible +for creating what is likely + +461 +00:19:45,810 --> 00:19:49,470 +the best known artificial +intelligence tool in the world, + +462 +00:19:49,470 --> 00:19:50,303 +ChatGPT. + +463 +00:19:51,420 --> 00:19:53,190 +ChatGPT is a large language model + +464 +00:19:53,190 --> 00:19:56,160 +that answers questions put +to it in natural language. + +465 +00:19:56,160 --> 00:19:58,440 +For example, what are the challenges + +466 +00:19:58,440 --> 00:20:01,650 +in trying to understand the +nature of consciousness? + +467 +00:20:01,650 --> 00:20:04,260 +Reid explored the ins and outs +of this emerging technology + +468 +00:20:04,260 --> 00:20:06,607 +by actually co-authoring +his most recent book, + +469 +00:20:06,607 --> 00:20:09,420 +"Impromptu" with GPT-4. + +470 +00:20:09,420 --> 00:20:11,730 +We wanted to talk to Reid about +how artificial intelligence + +471 +00:20:11,730 --> 00:20:14,727 +could help us better +understand human intelligence + +472 +00:20:14,727 --> 00:20:16,893 +and what it means to be conscious. + +473 +00:20:17,760 --> 00:20:21,060 +When was the first time you remember + +474 +00:20:21,060 --> 00:20:23,970 +thinking about artificial intelligence? + +475 +00:20:23,970 --> 00:20:26,550 +- Well my undergraduate +major, Symbolic Systems, + +476 +00:20:26,550 --> 00:20:29,010 +is basically artificial +intelligence and cognitive science. + +477 +00:20:29,010 --> 00:20:32,910 +So I was interested in how +we think, how we speak, + +478 +00:20:32,910 --> 00:20:35,340 +how we understand ourselves, +how we understand each other + +479 +00:20:35,340 --> 00:20:38,700 +and how we do that both +individually and collaboratively. + +480 +00:20:38,700 --> 00:20:41,970 +And Stanford had a great +artificial intelligence department, + +481 +00:20:41,970 --> 00:20:44,820 +and part of why it ended +up being computation + +482 +00:20:44,820 --> 00:20:48,690 +and cognition was my specific +suggestion was kind of like, + +483 +00:20:48,690 --> 00:20:53,690 +"Okay, these cognition +capabilities by these machines + +484 +00:20:54,180 --> 00:20:58,110 +help us understand our own, +help us amplify our own, + +485 +00:20:58,110 --> 00:21:00,090 +might even create something really amazing + +486 +00:21:00,090 --> 00:21:01,920 +and understand what intelligence is + +487 +00:21:01,920 --> 00:21:03,480 +'cause we are very anthropocentric. + +488 +00:21:03,480 --> 00:21:05,280 +So it's like, well, +thinking is what humans do." + +489 +00:21:05,280 --> 00:21:06,113 +- Yeah. + +490 +00:21:06,113 --> 00:21:06,946 +- And you're like, + +491 +00:21:06,946 --> 00:21:08,280 +"Well, we certainly +are a very good example + +492 +00:21:08,280 --> 00:21:10,770 +of thinking beings and creatures. + +493 +00:21:10,770 --> 00:21:12,690 +But think about all the +other thinking creatures." + +494 +00:21:12,690 --> 00:21:15,870 +Like we generally are very negative + +495 +00:21:15,870 --> 00:21:18,210 +on how other animals think. + +496 +00:21:18,210 --> 00:21:20,910 +And like they think a lot +more than we think they do. + +497 +00:21:20,910 --> 00:21:23,253 +I mean they pair bond, they mate for life. + +498 +00:21:24,433 --> 00:21:26,880 +They coordinate in packs and groups. + +499 +00:21:26,880 --> 00:21:28,020 +I mean there's all kinds of things. + +500 +00:21:28,020 --> 00:21:29,495 +And we say, "Well, they don't really think + +501 +00:21:29,495 --> 00:21:30,360 +the way we think." + +502 +00:21:30,360 --> 00:21:31,680 +Well of course they don't +think the way we think, + +503 +00:21:31,680 --> 00:21:34,080 +but they do think, right? + +504 +00:21:34,080 --> 00:21:36,750 +Well, now we also have +another pattern of thinking. + +505 +00:21:36,750 --> 00:21:38,190 +How do these machines think? + +506 +00:21:38,190 --> 00:21:41,070 +'Cause, by the way, they +are thinking today too. + +507 +00:21:41,070 --> 00:21:43,170 +They're not thinking the way we are. + +508 +00:21:43,170 --> 00:21:45,360 +They may not be thinking +at our level of capability + +509 +00:21:45,360 --> 00:21:48,990 +in some regard, but it's a +pattern of thought, right? + +510 +00:21:48,990 --> 00:21:51,240 +And so you think about, +okay, how do we understand + +511 +00:21:51,240 --> 00:21:52,740 +all of these different patterns of thought + +512 +00:21:52,740 --> 00:21:55,540 +and where are they similar +and where are they different? + +513 +00:21:57,420 --> 00:22:00,900 +- Okay, Descartes is, "I +think, therefore I am." + +514 +00:22:00,900 --> 00:22:02,100 +- Yes. +- Right, + +515 +00:22:02,100 --> 00:22:04,710 +and in general with respect to philosophy, + +516 +00:22:04,710 --> 00:22:09,030 +there's no uniformity of +agreement that I can really know + +517 +00:22:09,030 --> 00:22:11,490 +that you are having a conscious experience + +518 +00:22:11,490 --> 00:22:14,760 +in the same way that I am +having a conscious experience. + +519 +00:22:14,760 --> 00:22:16,110 +Is that true or no + +520 +00:22:16,110 --> 00:22:18,870 +or do you disagree? +- Well, it's complicated. + +521 +00:22:18,870 --> 00:22:20,400 +- Okay. + +522 +00:22:20,400 --> 00:22:22,980 +- So part of what I think Wittgenstein + +523 +00:22:22,980 --> 00:22:26,073 +and other philosophers did +in upgrading Descartes, + +524 +00:22:27,030 --> 00:22:28,380 +to put it in fairly simple terms: + +525 +00:22:28,380 --> 00:22:30,120 +So he says, "I think, therefore I am," + +526 +00:22:30,120 --> 00:22:31,380 +because I go through this doubt + +527 +00:22:31,380 --> 00:22:32,790 +and I realize that I must exist + +528 +00:22:32,790 --> 00:22:34,560 +in order to doubt that I'm existing. + +529 +00:22:34,560 --> 00:22:36,930 +So okay I'm formulating +a thought about like, + +530 +00:22:36,930 --> 00:22:38,670 +I think therefore I exist. + +531 +00:22:38,670 --> 00:22:39,990 +How do I formulate that thought? + +532 +00:22:39,990 --> 00:22:41,370 +How does it have any coherence? + +533 +00:22:41,370 --> 00:22:46,370 +How is it communicable +to myself or to you? + +534 +00:22:47,070 --> 00:22:49,230 +And when you begin analyzing language, + +535 +00:22:49,230 --> 00:22:51,930 +you begin to realize +that in the pattern of it + +536 +00:22:51,930 --> 00:22:54,630 +there may be some kind of, as it were, + +537 +00:22:54,630 --> 00:22:58,290 +transcendental observations +about the nature of reality + +538 +00:22:58,290 --> 00:23:00,600 +that come about if you believe- + +539 +00:23:00,600 --> 00:23:02,670 +- Uh-huh, I think I +understand what you just said, + +540 +00:23:02,670 --> 00:23:05,132 +but you may need to explain +that in more detail. + +541 +00:23:05,132 --> 00:23:05,965 +But go ahead. + +542 +00:23:05,965 --> 00:23:09,720 +- Yes, if you believe that +we are actually succeeding + +543 +00:23:09,720 --> 00:23:12,900 +in communicating at all +versus making random noises. + +544 +00:23:12,900 --> 00:23:13,733 +- Okay. + +545 +00:23:13,733 --> 00:23:15,840 +- So then you begin to go +to, okay, what do words mean + +546 +00:23:15,840 --> 00:23:18,210 +and how do we apply a word like conscious? + +547 +00:23:18,210 --> 00:23:20,250 +And I say, "I am conscious +and you're conscious" + +548 +00:23:20,250 --> 00:23:23,490 +and we learn the Wittgenstein phrases, + +549 +00:23:23,490 --> 00:23:26,340 +we're a form of life and +we play a language game. + +550 +00:23:26,340 --> 00:23:29,610 +And Wittgenstein's argument would be + +551 +00:23:29,610 --> 00:23:32,400 +because of the way the +word consciousness works + +552 +00:23:32,400 --> 00:23:35,250 +in our form of language we do actually, + +553 +00:23:35,250 --> 00:23:40,250 +in fact, share some +experience that is objective + +554 +00:23:40,320 --> 00:23:41,820 +and shared even though it is + +555 +00:23:41,820 --> 00:23:43,800 +each of our subjective consciousnesses. + +556 +00:23:43,800 --> 00:23:44,940 +- Okay. +- Now, that doesn't mean + +557 +00:23:44,940 --> 00:23:46,710 +that that our consciousness +are exactly the same. + +558 +00:23:46,710 --> 00:23:50,160 +Like where I smell something +different when I smell apricot + +559 +00:23:50,160 --> 00:23:50,993 +and you smell something else- +- Right, right, right. + +560 +00:23:50,993 --> 00:23:53,053 +- When you smell apricot- + +561 +00:23:53,053 --> 00:23:54,719 +- The quality of- +- Yes, the quality of it. + +562 +00:23:54,719 --> 00:23:56,760 +Maybe there's something that is diverse + +563 +00:23:56,760 --> 00:23:58,140 +and subjective in it, + +564 +00:23:58,140 --> 00:24:00,870 +but we learn in our use of language + +565 +00:24:00,870 --> 00:24:03,210 +the pattern by which we +go, "Oh, I smell apricot," + +566 +00:24:03,210 --> 00:24:05,790 +and we synchronize in our language dances + +567 +00:24:05,790 --> 00:24:07,138 +with each other what that is. + +568 +00:24:07,138 --> 00:24:08,640 +And so we have some level of quality + +569 +00:24:08,640 --> 00:24:12,028 +of shared experience in what that is. + +570 +00:24:12,028 --> 00:24:16,260 +And so there is, in forms of life, + +571 +00:24:16,260 --> 00:24:20,220 +a presumption that successful language use + +572 +00:24:20,220 --> 00:24:25,220 +does lead to some observations +about the way the world is, + +573 +00:24:25,800 --> 00:24:29,400 +not just by science, but by +our ability to communicate + +574 +00:24:29,400 --> 00:24:30,990 +to each other about the worlds + +575 +00:24:30,990 --> 00:24:32,670 +that we are mutually living in. + +576 +00:24:32,670 --> 00:24:33,900 +- Okay, so I'm persuaded + +577 +00:24:33,900 --> 00:24:35,640 +that you are also conscious then. + +578 +00:24:35,640 --> 00:24:36,473 +- Yes. + +579 +00:24:36,473 --> 00:24:39,570 +- But we are living in a +moment, where fairly recently, + +580 +00:24:39,570 --> 00:24:42,780 +there's been this thunder +clap of excitement + +581 +00:24:42,780 --> 00:24:47,780 +and energy with and around AI with ChatGPT + +582 +00:24:47,970 --> 00:24:49,920 +and all of these large language models. + +583 +00:24:49,920 --> 00:24:52,740 +And it's remarkable + +584 +00:24:52,740 --> 00:24:55,440 +how quickly the +developments are happening. + +585 +00:24:55,440 --> 00:24:58,020 +And I understand why people +would say things like, + +586 +00:24:58,020 --> 00:24:59,790 +"It's not conscious." + +587 +00:24:59,790 --> 00:25:02,100 +But it seems to me that there's something + +588 +00:25:02,100 --> 00:25:04,830 +about the way these mechanisms, +which are being built + +589 +00:25:04,830 --> 00:25:07,950 +and which we largely +understand what's happening, + +590 +00:25:07,950 --> 00:25:10,350 +how they seem to do things in a way + +591 +00:25:10,350 --> 00:25:12,870 +that's kind of mechanistic. + +592 +00:25:12,870 --> 00:25:15,360 +But I suppose we do things +in a way that's mechanistic, + +593 +00:25:15,360 --> 00:25:17,853 +but we also have a conscious experience. + +594 +00:25:18,960 --> 00:25:21,300 +And how will we know if the machines + +595 +00:25:21,300 --> 00:25:23,040 +are having some sort of +conscious experience, + +596 +00:25:23,040 --> 00:25:27,090 +in addition, to the mechanistic +thing that's happening? + +597 +00:25:27,090 --> 00:25:29,790 +Is it preposterous to think +that, that might be going on? + +598 +00:25:29,790 --> 00:25:32,130 +- It's certainly not preposterous, + +599 +00:25:32,130 --> 00:25:35,331 +although it's preposterous the +way that some people say it. + +600 +00:25:35,331 --> 00:25:36,870 +'Cause I think right now +the machines are much closer + +601 +00:25:36,870 --> 00:25:39,120 +to tools than they are to creatures. + +602 +00:25:39,120 --> 00:25:41,550 +Because part of how we make judgements + +603 +00:25:41,550 --> 00:25:44,310 +and consciousness is like one of us + +604 +00:25:44,310 --> 00:25:46,743 +will say something to +each other that we'll go, + +605 +00:25:47,610 --> 00:25:49,710 +"Oh that is, actually, +you've shown me something + +606 +00:25:49,710 --> 00:25:51,290 +about the experience of that." + +607 +00:25:51,290 --> 00:25:55,980 +Or I see your response +in kind of in delight + +608 +00:25:55,980 --> 00:25:57,180 +or in pain with this + +609 +00:25:57,180 --> 00:26:00,300 +and then I see a reflection +of that in how I would do it. + +610 +00:26:00,300 --> 00:26:02,490 +And so that's part of +how we do these things + +611 +00:26:02,490 --> 00:26:05,310 +and the devices aren't there right now. + +612 +00:26:05,310 --> 00:26:06,810 +There's nothing that says + +613 +00:26:06,810 --> 00:26:09,750 +the devices couldn't get +there in some version. + +614 +00:26:09,750 --> 00:26:11,730 +- Right. +- And part of the amazement + +615 +00:26:11,730 --> 00:26:14,160 +of that is, well, how do we learn better + +616 +00:26:14,160 --> 00:26:15,873 +about ourselves in that, too. + +617 +00:26:16,860 --> 00:26:19,110 +Like for example even playing with GPT-4, + +618 +00:26:19,110 --> 00:26:22,260 +which I've been playing +with since last August, + +619 +00:26:22,260 --> 00:26:25,440 +when I go, "Wow, this thing +can do a number of things + +620 +00:26:25,440 --> 00:26:28,410 +better than 99% of human beings." + +621 +00:26:28,410 --> 00:26:30,960 +All right, what's the role of specialness? + +622 +00:26:30,960 --> 00:26:32,790 +Like what are the things that we still do + +623 +00:26:32,790 --> 00:26:34,650 +that we are so much better than this at? + +624 +00:26:34,650 --> 00:26:37,890 +And so then how do we still +use this as an amplifier? + +625 +00:26:37,890 --> 00:26:40,050 +I think is one of the great questions + +626 +00:26:40,050 --> 00:26:44,517 +about how do we come to +understand other presences, + +627 +00:26:46,080 --> 00:26:48,120 +cognitive entities in ourselves + +628 +00:26:48,120 --> 00:26:53,120 +and how do we have a elevated +existence by partnering, + +629 +00:26:54,600 --> 00:26:56,283 +dancing together, etc. + +630 +00:27:03,060 --> 00:27:04,830 +- I don't think consciousness +is all or nothing. + +631 +00:27:04,830 --> 00:27:06,390 +It's clearly a continuum + +632 +00:27:06,390 --> 00:27:08,820 +and it's a continuum within an individual. + +633 +00:27:08,820 --> 00:27:11,820 +You know I'm more +conscious when I'm awake. + +634 +00:27:11,820 --> 00:27:14,820 +And within a collection of species; + +635 +00:27:14,820 --> 00:27:16,500 +you know I think certain species + +636 +00:27:16,500 --> 00:27:18,870 +are more conscious than other species + +637 +00:27:18,870 --> 00:27:20,880 +and I think it's true +with machines as well. + +638 +00:27:20,880 --> 00:27:23,820 +You know maybe, I don't think +that we have any machines + +639 +00:27:23,820 --> 00:27:27,660 +that are conscious in any +interesting sense yet. + +640 +00:27:27,660 --> 00:27:30,723 +But I think if we ever do, +they'll be part of that spectrum. + +641 +00:27:32,190 --> 00:27:33,023 +- Melanie Mitchell is + +642 +00:27:33,023 --> 00:27:34,560 +a professor at the Santa Fe Institute + +643 +00:27:34,560 --> 00:27:37,187 +who studied artificial +intelligence for decades. + +644 +00:27:37,187 --> 00:27:38,520 +- Technical thing I'm gonna say tonight. + +645 +00:27:38,520 --> 00:27:41,100 +- She's also the author of +"Artificial Intelligence: + +646 +00:27:41,100 --> 00:27:43,200 +A Guide for Thinking Humans". + +647 +00:27:43,200 --> 00:27:46,410 +- I've been interested in science + +648 +00:27:46,410 --> 00:27:48,690 +my whole life, essentially. + +649 +00:27:48,690 --> 00:27:52,350 +But I got really interested +in the topic of intelligence + +650 +00:27:52,350 --> 00:27:55,200 +when I read Doug Hofstadter's +book, "Godel, Escher, Bach", + +651 +00:27:55,200 --> 00:27:57,600 +way back when I graduated from college. + +652 +00:27:57,600 --> 00:28:02,190 +It was about how intelligence can emerge + +653 +00:28:02,190 --> 00:28:05,640 +from this giant collection +of non-intelligent things + +654 +00:28:05,640 --> 00:28:10,140 +like cells in the body, +neurons and their connections. + +655 +00:28:10,140 --> 00:28:11,610 +So a neuron isn't intelligent, + +656 +00:28:11,610 --> 00:28:13,230 +I think most people would agree to that. + +657 +00:28:13,230 --> 00:28:15,090 +But when you put a huge +collection of them together + +658 +00:28:15,090 --> 00:28:17,700 +and they interact in certain ways. + +659 +00:28:17,700 --> 00:28:19,890 +What we call intelligence +emerges along with + +660 +00:28:19,890 --> 00:28:23,280 +a lot of other kind of +mental cognitive qualities, + +661 +00:28:23,280 --> 00:28:26,040 +like emotions, self-awareness + +662 +00:28:26,040 --> 00:28:28,020 +and other things of that nature. + +663 +00:28:28,020 --> 00:28:31,680 +So that was incredibly fascinating to me. + +664 +00:28:31,680 --> 00:28:33,720 +And I kind of got into AI + +665 +00:28:33,720 --> 00:28:35,730 +because I went to work with Hofstadter + +666 +00:28:35,730 --> 00:28:36,930 +and that's what he was working on. + +667 +00:28:36,930 --> 00:28:39,870 +I mean it was sort of a mix +of cognitive science and AI, + +668 +00:28:39,870 --> 00:28:40,703 +'cause we were interested + +669 +00:28:40,703 --> 00:28:42,570 +in understanding human intelligence + +670 +00:28:42,570 --> 00:28:46,323 +by trying to develop +intelligence in machines. + +671 +00:28:50,430 --> 00:28:53,280 +All this AI controversy +about consciousness + +672 +00:28:53,280 --> 00:28:54,900 +has kind of brought it into + +673 +00:28:54,900 --> 00:28:57,390 +the limelight of the broader public + +674 +00:28:57,390 --> 00:29:00,300 +thinking about like what is consciousness? + +675 +00:29:00,300 --> 00:29:03,314 +What is this thing we call self-awareness? + +676 +00:29:03,314 --> 00:29:07,170 +How is that different from +things that are not self-aware? + +677 +00:29:07,170 --> 00:29:08,820 +You know things that people +don't usually talk about. + +678 +00:29:08,820 --> 00:29:11,580 +But you know we have these systems now + +679 +00:29:11,580 --> 00:29:14,280 +that talk to us in natural language + +680 +00:29:14,280 --> 00:29:17,400 +and they seem like they're self-aware. + +681 +00:29:17,400 --> 00:29:20,910 +We know that they probably +aren't, almost certainly aren't. + +682 +00:29:20,910 --> 00:29:22,950 +But how would we tell? + +683 +00:29:22,950 --> 00:29:24,630 +What kind of tests would we give? + +684 +00:29:24,630 --> 00:29:28,410 +And then we start realizing +that these questions + +685 +00:29:28,410 --> 00:29:30,060 +don't just apply to like AI; + +686 +00:29:30,060 --> 00:29:33,900 +they apply to things like +when is an infant self-aware? + +687 +00:29:33,900 --> 00:29:35,670 +- Sure. +- It used to be, + +688 +00:29:35,670 --> 00:29:37,800 +you know maybe 30, 40 years ago, + +689 +00:29:37,800 --> 00:29:40,800 +people used to think that +infants didn't feel pain. + +690 +00:29:40,800 --> 00:29:42,570 +- Hmm. +- And they would do surgeries + +691 +00:29:42,570 --> 00:29:45,030 +on newborn babies without anesthesia. + +692 +00:29:45,030 --> 00:29:46,593 +You know it seems crazy now. + +693 +00:29:47,520 --> 00:29:48,960 +You know our understanding + +694 +00:29:48,960 --> 00:29:53,960 +of how consciousness +develops, it's increasing. + +695 +00:29:57,840 --> 00:29:59,730 +Often, a lot of people don't think animals + +696 +00:29:59,730 --> 00:30:02,220 +have consciousness and that, therefore, + +697 +00:30:02,220 --> 00:30:05,640 +it's fine to use them as farm laborers + +698 +00:30:05,640 --> 00:30:08,130 +and to eat them and +all that kind of thing. + +699 +00:30:08,130 --> 00:30:10,830 +But we really have very +little understanding + +700 +00:30:10,830 --> 00:30:13,560 +of these questions about consciousness. + +701 +00:30:13,560 --> 00:30:18,560 +So I think AI has helped us to really see + +702 +00:30:18,990 --> 00:30:21,120 +that this is an important question, + +703 +00:30:21,120 --> 00:30:23,740 +not just for philosophy, +but for real life. + +704 +00:30:23,740 --> 00:30:25,170 +- Yeah. +- And for + +705 +00:30:25,170 --> 00:30:26,553 +making moral decisions. + +706 +00:30:29,676 --> 00:30:32,190 +- Good morning to you. + +707 +00:30:32,190 --> 00:30:34,240 +- And good afternoon to you, sir. + +708 +00:30:35,700 --> 00:30:38,160 +- Whatever we have in our heads + +709 +00:30:38,160 --> 00:30:41,820 +which enables us to understand things + +710 +00:30:41,820 --> 00:30:43,920 +is not something you +can put on a computer. + +711 +00:30:43,920 --> 00:30:45,810 +It's very relevant, of course, + +712 +00:30:45,810 --> 00:30:47,423 +to what people say now about AI. + +713 +00:30:47,423 --> 00:30:49,650 +You see they seem to say, "Oh well, + +714 +00:30:49,650 --> 00:30:52,170 +these AI systems they're so clever, + +715 +00:30:52,170 --> 00:30:55,950 +so smart that they'll supersede us." + +716 +00:30:55,950 --> 00:30:57,843 +But to me, that's a mistake. + +717 +00:30:58,680 --> 00:31:00,450 +They get pretty clever + +718 +00:31:00,450 --> 00:31:02,850 +and they can do all sorts of +things faster than we can, + +719 +00:31:02,850 --> 00:31:05,370 +sure, but they don't understand anything. + +720 +00:31:05,370 --> 00:31:08,010 +They don't understand what they're doing. + +721 +00:31:08,010 --> 00:31:12,330 +Understanding is a quality +which needs consciousness + +722 +00:31:12,330 --> 00:31:14,030 +and they don't have consciousness. + +723 +00:31:14,910 --> 00:31:16,980 +- Sir Roger Penrose is a mathematician, + +724 +00:31:16,980 --> 00:31:19,800 +physicist and philosopher of science. + +725 +00:31:19,800 --> 00:31:21,420 +He's won the Nobel Prize in Physics + +726 +00:31:21,420 --> 00:31:22,830 +for his work on black holes + +727 +00:31:22,830 --> 00:31:24,990 +and shares a Wolf Prize +with Stephen Hawking + +728 +00:31:24,990 --> 00:31:28,080 +for their contributions to the +theory of general relativity. + +729 +00:31:28,080 --> 00:31:31,410 +In 1988, he published +"The Emperor's New Mind," + +730 +00:31:31,410 --> 00:31:34,383 +a book venturing into the +realm of consciousness studies. + +731 +00:31:35,430 --> 00:31:37,110 +Most approaches to +explaining consciousness + +732 +00:31:37,110 --> 00:31:39,450 +using classical physics +end up describing something + +733 +00:31:39,450 --> 00:31:43,170 +that sounds like a really +complicated computer or AI. + +734 +00:31:43,170 --> 00:31:45,630 +But for some scientists and philosophers, + +735 +00:31:45,630 --> 00:31:48,330 +there's a nagging sense that +there's still something special + +736 +00:31:48,330 --> 00:31:50,430 +about consciousness that can't be captured + +737 +00:31:50,430 --> 00:31:52,500 +by classical physics alone- + +738 +00:31:52,500 --> 00:31:56,103 +and, as a result, can't be +reduced to simple computation. + +739 +00:31:57,600 --> 00:32:00,270 +This is what led Roger to +explore whether the weirdness + +740 +00:32:00,270 --> 00:32:03,120 +and mystery of quantum +physics might help explain + +741 +00:32:03,120 --> 00:32:06,090 +the weirdness and +mystery of consciousness. + +742 +00:32:06,090 --> 00:32:08,310 +- So I began to wonder about, + +743 +00:32:08,310 --> 00:32:11,820 +"Well, what is it that +we can have in our heads + +744 +00:32:11,820 --> 00:32:14,730 +which isn't something you +could put on a computer." + +745 +00:32:14,730 --> 00:32:17,413 +Now I am a physicalist, + +746 +00:32:17,413 --> 00:32:20,370 +in the sense that I believe +what's going on in our heads + +747 +00:32:20,370 --> 00:32:22,560 +is part of the physical world. + +748 +00:32:22,560 --> 00:32:25,530 +And it's the same with +what's going on in this glass + +749 +00:32:25,530 --> 00:32:29,280 +or what's going on in this +thing, with this light. + +750 +00:32:29,280 --> 00:32:31,863 +All those things are part +of the physical world. + +751 +00:32:33,000 --> 00:32:37,050 +The argument I would make +is that consciousness, + +752 +00:32:37,050 --> 00:32:39,420 +if you make a conscious decision, + +753 +00:32:39,420 --> 00:32:42,840 +your conscious action +is not a computation, + +754 +00:32:42,840 --> 00:32:45,210 +but it's something which depends + +755 +00:32:45,210 --> 00:32:47,910 +on this mysterious part of physics + +756 +00:32:47,910 --> 00:32:50,820 +which is a sort of gap +in our understanding, + +757 +00:32:50,820 --> 00:32:52,970 +which is the collapse +of the wave function. + +758 +00:32:54,540 --> 00:32:55,500 +- In quantum mechanics, + +759 +00:32:55,500 --> 00:32:57,060 +the collapse of the wave function + +760 +00:32:57,060 --> 00:32:58,950 +refers to what happens when you try to, + +761 +00:32:58,950 --> 00:33:01,470 +actually, measure the +state of a quantum system + +762 +00:33:01,470 --> 00:33:03,540 +at a given moment in time. + +763 +00:33:03,540 --> 00:33:06,000 +The thing is quantum +entities like electrons + +764 +00:33:06,000 --> 00:33:09,660 +can exist in multiple +states at the same time. + +765 +00:33:09,660 --> 00:33:11,790 +Think of it like a roll of the dice. + +766 +00:33:11,790 --> 00:33:14,910 +When they're in the air, +they're all potential. + +767 +00:33:14,910 --> 00:33:17,430 +They have no numerical value at all. + +768 +00:33:17,430 --> 00:33:19,740 +But when they land, they collapse into + +769 +00:33:19,740 --> 00:33:24,240 +one of 21 possible combinations +for a pair of dice. + +770 +00:33:24,240 --> 00:33:25,650 +But the single number you land on + +771 +00:33:25,650 --> 00:33:27,420 +isn't an accurate description of the dice + +772 +00:33:27,420 --> 00:33:30,090 +as they exist when they're +moving through the air, + +773 +00:33:30,090 --> 00:33:33,750 +when all the possibilities +they could land on still exist. + +774 +00:33:33,750 --> 00:33:37,020 +Penrose theorized that, +perhaps, this quantum process + +775 +00:33:37,020 --> 00:33:40,350 +may have a role in +generating consciousness. + +776 +00:33:40,350 --> 00:33:42,810 +- There's a probability of +this, a probability of that. + +777 +00:33:42,810 --> 00:33:45,450 +But maybe that's not the whole story. + +778 +00:33:45,450 --> 00:33:47,130 +There's more to the story + +779 +00:33:47,130 --> 00:33:51,210 +which means that this +collapse of the wave function + +780 +00:33:51,210 --> 00:33:54,870 +is something which, in our brains, + +781 +00:33:54,870 --> 00:33:57,783 +we sort of harness whatever is going on. + +782 +00:33:58,650 --> 00:34:01,170 +And this was the point I +was trying to make in the, + +783 +00:34:01,170 --> 00:34:03,603 +you asked me about the +popular books I wrote, + +784 +00:34:04,597 --> 00:34:06,963 +or I can call them +semi-popular, if you like, + +785 +00:34:07,800 --> 00:34:10,830 +they're a little more technical +than many popular books. + +786 +00:34:10,830 --> 00:34:14,219 +And "The Emperors New Mind" +was the book I wrote first. + +787 +00:34:14,219 --> 00:34:18,000 +And I was trying to +promote this view that, + +788 +00:34:18,000 --> 00:34:21,120 +okay, there must be something +going on in our heads + +789 +00:34:21,120 --> 00:34:24,960 +which requires the collapse +of the wave function + +790 +00:34:24,960 --> 00:34:27,795 +and that, that is the +sort of foundation stone + +791 +00:34:27,795 --> 00:34:30,480 +of whatever consciousness is. + +792 +00:34:30,480 --> 00:34:31,652 +- Hmm. +- And Stuart Hameroff + +793 +00:34:31,652 --> 00:34:35,070 +read my book and he got hold of me + +794 +00:34:35,070 --> 00:34:38,489 +and said, "Well, evidently you don't know + +795 +00:34:38,489 --> 00:34:40,550 +about something else, +which you should know." + +796 +00:34:40,550 --> 00:34:43,360 +He didn't say it like that, +but these were microtubules + +797 +00:34:44,639 --> 00:34:47,639 +And I was completely +ignorant of microtubules, + +798 +00:34:47,639 --> 00:34:48,570 +he was absolutely right. + +799 +00:34:48,570 --> 00:34:51,389 +I didn't know what they were +for, I had never heard of them. + +800 +00:34:51,389 --> 00:34:54,360 +- Stuart Hameroff is an +anesthesiologist who, + +801 +00:34:54,360 --> 00:34:56,010 +around the same time in the 1980s, + +802 +00:34:56,010 --> 00:34:58,050 +was trying to understand consciousness + +803 +00:34:58,050 --> 00:35:00,633 +by studying the process +of shutting it off. + +804 +00:35:01,620 --> 00:35:03,630 +Together, Roger and Stuart theorized + +805 +00:35:03,630 --> 00:35:05,280 +that perhaps these microtubules, + +806 +00:35:05,280 --> 00:35:08,460 +tiny straw-like structures +inside ourselves + +807 +00:35:08,460 --> 00:35:10,650 +that help give our cells their shape + +808 +00:35:10,650 --> 00:35:13,320 +and act like highways for +important information, + +809 +00:35:13,320 --> 00:35:15,030 +that these microtubules could be + +810 +00:35:15,030 --> 00:35:17,610 +where these quantum processes occur, + +811 +00:35:17,610 --> 00:35:19,293 +giving rise to consciousness. + +812 +00:35:20,490 --> 00:35:23,550 +- Anyway, so we got together +and the idea started off, + +813 +00:35:23,550 --> 00:35:26,070 +I think nobody really believed us. + +814 +00:35:26,070 --> 00:35:27,630 +I think it's got to the point where + +815 +00:35:27,630 --> 00:35:29,550 +it's sort of one of the three + +816 +00:35:29,550 --> 00:35:32,340 +or four most prominent theories. + +817 +00:35:32,340 --> 00:35:34,950 +So it's taken sort of seriously. + +818 +00:35:34,950 --> 00:35:37,770 +And I think that it's regarded as, + +819 +00:35:37,770 --> 00:35:40,080 +certainly, a different angle + +820 +00:35:40,080 --> 00:35:41,580 +from what most people would think. + +821 +00:35:41,580 --> 00:35:42,960 +They tend to think it's some kind + +822 +00:35:42,960 --> 00:35:46,740 +of computer-like action in the brain. + +823 +00:35:46,740 --> 00:35:48,090 +And what we're trying to say is, + +824 +00:35:48,090 --> 00:35:49,840 +"No, it's something quite different." + +825 +00:35:51,150 --> 00:35:52,530 +- Penrose and Hameroff's theory + +826 +00:35:52,530 --> 00:35:54,810 +known as 'orchestrated +objective reduction' + +827 +00:35:54,810 --> 00:35:56,193 +remains controversial. + +828 +00:35:57,390 --> 00:35:58,223 +But it's not called + +829 +00:35:58,223 --> 00:36:00,960 +the hard problem of +consciousness for nothing. + +830 +00:36:00,960 --> 00:36:02,520 +There is no shortage of arguments + +831 +00:36:02,520 --> 00:36:03,900 +for and against, virtually, + +832 +00:36:03,900 --> 00:36:08,670 +every proposed explanation of +the thing that makes us, us. + +833 +00:36:08,670 --> 00:36:10,320 +When we were chatting a bit earlier + +834 +00:36:10,320 --> 00:36:12,720 +about science and religion, + +835 +00:36:12,720 --> 00:36:14,160 +I was having a little bit of trouble + +836 +00:36:14,160 --> 00:36:16,170 +squaring your perspective. + +837 +00:36:16,170 --> 00:36:19,890 +Because in one respect, I think +there's a sense that science + +838 +00:36:19,890 --> 00:36:22,710 +and religion shouldn't +be afraid of one another + +839 +00:36:22,710 --> 00:36:26,130 +and it oughta be able to address +some of the same questions. + +840 +00:36:26,130 --> 00:36:26,963 +But in another respect, + +841 +00:36:26,963 --> 00:36:30,600 +we are defining two very +different kind of approaches. + +842 +00:36:30,600 --> 00:36:31,800 +- Yes. +- So how do you + +843 +00:36:31,800 --> 00:36:35,310 +define religion and how +do you define science + +844 +00:36:35,310 --> 00:36:37,290 +relative to one another? + +845 +00:36:37,290 --> 00:36:40,780 +- Our definition of religion would be that + +846 +00:36:41,820 --> 00:36:46,820 +it's the manifestation of a +potential divinity in all of us + +847 +00:36:48,450 --> 00:36:51,180 +and the goal is to manifest +this divinity within us. + +848 +00:36:51,180 --> 00:36:52,200 +- Hm. +- You do it + +849 +00:36:52,200 --> 00:36:53,670 +through philosophy. + +850 +00:36:53,670 --> 00:36:55,530 +You do it through meditation. + +851 +00:36:55,530 --> 00:36:57,570 +You do it through devotional religion. + +852 +00:36:57,570 --> 00:36:59,220 +You do it through good works. + +853 +00:36:59,220 --> 00:37:01,830 +In all the ways in which humanity + +854 +00:37:01,830 --> 00:37:03,660 +has tried to become better and greater, + +855 +00:37:03,660 --> 00:37:06,480 +it is a manifestation of +the divinity within us. + +856 +00:37:06,480 --> 00:37:10,500 +And science, as far as we have it now, + +857 +00:37:10,500 --> 00:37:14,280 +is a quest to understand what reality is. + +858 +00:37:14,280 --> 00:37:18,060 +So far it has been focused +on external reality + +859 +00:37:18,060 --> 00:37:21,540 +and, curiously, it has ignored ourselves. + +860 +00:37:21,540 --> 00:37:25,470 +You know, at most, we +are focused on the body + +861 +00:37:25,470 --> 00:37:27,960 +and we've learned an +enormous lot about it. + +862 +00:37:27,960 --> 00:37:32,960 +But the science of the mind +is still in its infancy. + +863 +00:37:33,570 --> 00:37:36,750 +I mean if you ask a +materialist reductionist, + +864 +00:37:36,750 --> 00:37:37,683 +what's a thought? + +865 +00:37:39,122 --> 00:37:40,680 +There is no space for a thought. + +866 +00:37:40,680 --> 00:37:44,490 +You have to explain everything +in terms of matter and energy + +867 +00:37:44,490 --> 00:37:45,750 +and time and space. + +868 +00:37:45,750 --> 00:37:49,380 +Where in time, space, +matter, energy is a thought? + +869 +00:37:49,380 --> 00:37:50,850 +What they will immediately say is that, + +870 +00:37:50,850 --> 00:37:54,090 +of course, a thought is nothing +but activity in the brain. + +871 +00:37:54,090 --> 00:37:55,320 +But that's where you run into + +872 +00:37:55,320 --> 00:37:57,057 +the hard problem of consciousness. + +873 +00:37:57,057 --> 00:37:58,890 +And that's the biggest question + +874 +00:37:58,890 --> 00:38:00,930 +in consciousness studies today. + +875 +00:38:00,930 --> 00:38:04,740 +You know what exactly is consciousness? + +876 +00:38:04,740 --> 00:38:06,590 +That it cannot be reduced to a brain. + +877 +00:38:07,500 --> 00:38:12,500 +So even from a very rigorous, +strict scientific perspective, + +878 +00:38:12,690 --> 00:38:15,930 +you can no longer deny +that there is something + +879 +00:38:15,930 --> 00:38:18,930 +that it might be, in principle, +impossible to explain + +880 +00:38:18,930 --> 00:38:21,872 +through at least our +present idea of science. + +881 +00:38:21,872 --> 00:38:22,705 +- Um-hm. + +882 +00:38:22,705 --> 00:38:23,538 +- And I'm open, actually, + +883 +00:38:23,538 --> 00:38:25,260 +and people might think that you're a monk + +884 +00:38:25,260 --> 00:38:27,240 +and committed to religion, which I am, + +885 +00:38:27,240 --> 00:38:29,940 +but I'm also open in principle to the idea + +886 +00:38:29,940 --> 00:38:31,290 +that I could be completely wrong. + +887 +00:38:31,290 --> 00:38:32,250 +- Sure. +- And Richard Dawkins + +888 +00:38:32,250 --> 00:38:34,440 +or Daniel Dennett might +be completely right, + +889 +00:38:34,440 --> 00:38:36,750 +that it just might be matter. + +890 +00:38:36,750 --> 00:38:39,180 +And therefore, all our religion, + +891 +00:38:39,180 --> 00:38:42,630 +all of it might be just a +matter of culture, of practice. + +892 +00:38:42,630 --> 00:38:46,560 +Religion is good, but I +don't subscribe to that. + +893 +00:38:46,560 --> 00:38:48,690 +I subscribe to the heavy +metaphysical baggage + +894 +00:38:48,690 --> 00:38:50,880 +that there is an ultimate reality, + +895 +00:38:50,880 --> 00:38:52,470 +which you may dress up as God, + +896 +00:38:52,470 --> 00:38:54,480 +but something like that exists + +897 +00:38:54,480 --> 00:38:56,400 +and it's somehow deeply connected + +898 +00:38:56,400 --> 00:38:59,343 +to our existence as consciousness +and as conscious beings. + +899 +00:39:02,430 --> 00:39:05,280 +- There are many theologians + +900 +00:39:05,280 --> 00:39:08,670 +who have a very different +perspective on consciousness. + +901 +00:39:08,670 --> 00:39:09,870 +And they imagine, perhaps, + +902 +00:39:09,870 --> 00:39:13,500 +that there is this kind of +supernatural world that exists + +903 +00:39:13,500 --> 00:39:15,720 +and is perhaps outside of our own world + +904 +00:39:15,720 --> 00:39:17,790 +and that our conscious experience, + +905 +00:39:17,790 --> 00:39:19,500 +separate from the material world, + +906 +00:39:19,500 --> 00:39:20,730 +is something else altogether. + +907 +00:39:20,730 --> 00:39:22,770 +That it can't possibly be understood + +908 +00:39:22,770 --> 00:39:25,260 +in the way that you are +trying to understand it. + +909 +00:39:25,260 --> 00:39:28,830 +Do you have a general sentiment + +910 +00:39:28,830 --> 00:39:31,620 +with respect to the competing approach? + +911 +00:39:31,620 --> 00:39:34,080 +- Well, very often it's +not so much competing + +912 +00:39:34,080 --> 00:39:36,150 +because they agree that in this life, + +913 +00:39:36,150 --> 00:39:38,040 +my brain is essential for conscious. + +914 +00:39:38,040 --> 00:39:39,900 +If I lose my brain due to an accident + +915 +00:39:39,900 --> 00:39:42,180 +or gunshot or whatever, +conscious will be gone. + +916 +00:39:42,180 --> 00:39:43,200 +- Yeah. +- So in that sense, + +917 +00:39:43,200 --> 00:39:44,250 +we both agree. + +918 +00:39:44,250 --> 00:39:47,880 +They offer a larger narrative +that says, "Well then you die, + +919 +00:39:47,880 --> 00:39:49,410 +but then God will resurrect you + +920 +00:39:49,410 --> 00:39:50,850 +in the fullness of time." +- Right, right. + +921 +00:39:50,850 --> 00:39:52,183 +- I have no proof of that. + +922 +00:39:52,183 --> 00:39:54,540 +I have no disprove that it doesn't happen. + +923 +00:39:54,540 --> 00:39:56,040 +But for myself it doesn't, + +924 +00:39:56,040 --> 00:39:58,551 +because there's simply no evidence for it. + +925 +00:39:58,551 --> 00:40:00,450 +There's this other view, +this idealism view, + +926 +00:40:00,450 --> 00:40:03,480 +which is sort of non-religious, +that says, "Yes ultimately, + +927 +00:40:03,480 --> 00:40:05,730 +it's all a manifestation of the mental." + +928 +00:40:05,730 --> 00:40:10,110 +And if you die, yes, +your individual conscious + +929 +00:40:10,110 --> 00:40:12,540 +will be absorbed into the greater whole, + +930 +00:40:12,540 --> 00:40:14,280 +think of it like an ocean. + +931 +00:40:14,280 --> 00:40:17,610 +You are right now an individual +drop, with your own ego. + +932 +00:40:17,610 --> 00:40:20,700 +But then when you die, you'll +return to the infinite ocean + +933 +00:40:20,700 --> 00:40:22,500 +and be part of the larger conscious. + +934 +00:40:22,500 --> 00:40:23,333 +So in that sense, + +935 +00:40:23,333 --> 00:40:25,890 +what is most fundamental +is not the physical, + +936 +00:40:25,890 --> 00:40:26,940 +it's actually the mental. + +937 +00:40:26,940 --> 00:40:28,500 +- Um-hm. +- But it's not + +938 +00:40:28,500 --> 00:40:29,340 +personal survival. + +939 +00:40:29,340 --> 00:40:30,900 +It's very different from the classical, + +940 +00:40:30,900 --> 00:40:32,430 +you know you will be there in heaven + +941 +00:40:32,430 --> 00:40:34,290 +floating around in some cloud in paradise. + +942 +00:40:34,290 --> 00:40:35,123 +- Right. + +943 +00:40:36,150 --> 00:40:39,900 +It's interesting that you +could think about all there is, + +944 +00:40:39,900 --> 00:40:42,840 +the sort of mystery of all of that + +945 +00:40:42,840 --> 00:40:46,650 +and that drop could either +be descending into some void + +946 +00:40:46,650 --> 00:40:48,150 +never to be heard from again + +947 +00:40:48,150 --> 00:40:51,000 +or returning to become +a part of all there is. + +948 +00:40:51,000 --> 00:40:54,120 +And one could hold the +same thought, essentially, + +949 +00:40:54,120 --> 00:40:55,650 +and frame it in those different ways- + +950 +00:40:55,650 --> 00:40:57,023 +- In two different ways, yes. +- Yeah. + +951 +00:40:57,023 --> 00:40:57,870 +- And the physicalist would say, + +952 +00:40:57,870 --> 00:41:01,640 +yeah, that drop disappears into +the void, as you just said. + +953 +00:41:01,640 --> 00:41:02,760 +Or an idealist would say, no, + +954 +00:41:02,760 --> 00:41:05,310 +it returns sort of to that the ooze + +955 +00:41:05,310 --> 00:41:08,040 +or substance from which it all came. + +956 +00:41:08,040 --> 00:41:09,180 +It's a very different view, + +957 +00:41:09,180 --> 00:41:11,520 +but you know might be true. + +958 +00:41:11,520 --> 00:41:15,210 +- Yeah, what if this is just ineffable? + +959 +00:41:15,210 --> 00:41:16,980 +We can approach it, + +960 +00:41:16,980 --> 00:41:19,890 +but we'll always be infinitely far away. + +961 +00:41:19,890 --> 00:41:21,840 +- Yeah, there's no +guarantee that there will be + +962 +00:41:21,840 --> 00:41:23,940 +a final ultimate theory of consciousness. + +963 +00:41:23,940 --> 00:41:25,170 +But I know there's a guarantee + +964 +00:41:25,170 --> 00:41:27,820 +that there will not be such +a theory if we don't try. + +965 +00:41:29,250 --> 00:41:31,320 +- The debate over how consciousness works, + +966 +00:41:31,320 --> 00:41:33,835 +where it resides and why we have, + +967 +00:41:33,835 --> 00:41:36,900 +it seems unlikely to be +resolved in my lifetime. + +968 +00:41:36,900 --> 00:41:39,270 +But as humans, we're +prone to filling in gaps + +969 +00:41:39,270 --> 00:41:42,480 +in our understanding with +speculation and superstition. + +970 +00:41:42,480 --> 00:41:44,190 +But I've gotta say that with something + +971 +00:41:44,190 --> 00:41:47,430 +as fundamental to our +experience as consciousness, + +972 +00:41:47,430 --> 00:41:50,910 +it's hard to imagine that it +doesn't have some purpose. + +973 +00:41:50,910 --> 00:41:52,920 +- Maybe there is a teleology + +974 +00:41:52,920 --> 00:41:55,020 +towards the elevation of consciousness + +975 +00:41:55,020 --> 00:41:55,980 +and being in the Universe, + +976 +00:41:55,980 --> 00:41:58,110 +which we are somehow participants in, + +977 +00:41:58,110 --> 00:41:59,940 +may be leading examples of. + +978 +00:41:59,940 --> 00:42:02,190 +That would be a beautiful existence. + +979 +00:42:02,190 --> 00:42:03,090 +- You would like that to be- + +980 +00:42:03,090 --> 00:42:05,610 +- That would be a great, +that'd be wonderful. + +981 +00:42:05,610 --> 00:42:06,443 +- Okay. +- You know like I think + +982 +00:42:06,443 --> 00:42:08,100 +the Buddhism karmic rebirth + +983 +00:42:08,100 --> 00:42:11,310 +is one of the most elegant metaphysics, + +984 +00:42:11,310 --> 00:42:14,190 +should it actually, in fact, really exist. + +985 +00:42:14,190 --> 00:42:16,830 +Look, say the world +doesn't have a teleology, + +986 +00:42:16,830 --> 00:42:19,740 +there's no reason that we +need to treat the world + +987 +00:42:19,740 --> 00:42:21,090 +as if it doesn't. + +988 +00:42:21,090 --> 00:42:24,960 +We can say, "No, we think +that it is a elegant thing, + +989 +00:42:24,960 --> 00:42:27,180 +a thing of beauty, a thing of importance + +990 +00:42:27,180 --> 00:42:30,510 +about the expansion of +consciousness in the Universe." + +991 +00:42:30,510 --> 00:42:32,370 +That is the mission that we're on, + +992 +00:42:32,370 --> 00:42:33,600 +that we are demonstrating + +993 +00:42:33,600 --> 00:42:35,520 +and it doesn't matter if you say, wow, + +994 +00:42:35,520 --> 00:42:40,080 +there's only like physics +and atoms and so forth. + +995 +00:42:40,080 --> 00:42:43,200 +But let's act in a way such that, + +996 +00:42:43,200 --> 00:42:46,560 +that the nobility of that quest + +997 +00:42:46,560 --> 00:42:49,500 +of becoming our aspirational humanity, + +998 +00:42:49,500 --> 00:42:54,500 +becoming more conscious +is the point of life. + +999 +00:42:54,510 --> 00:42:56,670 +We can choose that. We can anoint that. + +1000 +00:42:56,670 --> 00:42:59,943 +We can say that is where we're going. + +1001 +00:43:02,880 --> 00:43:05,013 +- Consciousness is a gift. + +1002 +00:43:05,970 --> 00:43:07,770 +Whatever it turns out to be + +1003 +00:43:07,770 --> 00:43:11,433 +and whether or not it has +a purpose, it is present. + +1004 +00:43:12,390 --> 00:43:15,240 +It's the foundation of all human action: + +1005 +00:43:15,240 --> 00:43:17,073 +past, present and future. + +1006 +00:43:17,940 --> 00:43:20,550 +It imbues us with the +power to shape our world, + +1007 +00:43:20,550 --> 00:43:22,060 +to understand the Universe- + +1008 +00:43:23,820 --> 00:43:26,280 +and, sometimes, even to step back + +1009 +00:43:26,280 --> 00:43:31,189 +and appreciate that +feeling of life itself. +
