1 00:00:39,004 --> 00:00:40,638 Let me tell you a joke. 4 00:00:40,639 --> 00:00:42,107 Somebody apparently once went up 5 00:00:42,108 --> 00:00:44,542 to the great philosopher Wittgenstein, 6 00:00:44,543 --> 00:00:47,612 and said "What a lot of morons people back in the Middle Ages 7 00:00:47,613 --> 00:00:50,382 must have been to have looked every morning 8 00:00:50,383 --> 00:00:53,385 at what is going on behind me now, the dawn, 9 00:00:53,386 --> 00:00:55,553 and to have thought that what they were seeing 10 00:00:55,554 --> 00:00:57,389 was the Sun going round the Earth, 11 00:00:57,390 --> 00:00:59,857 when, as every school kid knows, the Earth goes round the Sun 12 00:00:59,858 --> 00:01:02,294 and it doesn't take too many brains to understand that". 13 00:01:02,295 --> 00:01:04,429 To which Wittgenstein replied, 14 00:01:04,430 --> 00:01:07,031 "Yeah, but I wonder what it would have looked like 15 00:01:07,032 --> 00:01:09,701 if the Sun had been going round the Earth". 16 00:01:09,702 --> 00:01:12,103 The point being, of course, 17 00:01:12,104 --> 00:01:15,507 it would have looked exactly the same. 18 00:01:15,508 --> 00:01:18,976 You see what your knowledge tells you you are seeing. 19 00:01:26,986 --> 00:01:29,320 Well, that's what this series is going to be about: 20 00:01:29,321 --> 00:01:32,156 how, what you think the universe is 21 00:01:32,157 --> 00:01:35,059 and how you react to that, in everything you do, 22 00:01:35,060 --> 00:01:38,930 depends on what you know, and when that knowledge changes, 23 00:01:38,931 --> 00:01:42,067 for you, the universe changes. 24 00:01:42,068 --> 00:01:44,836 And that is as true for the whole of society 25 00:01:44,837 --> 00:01:46,505 as it is for the individual. 26 00:01:46,506 --> 00:01:48,973 We all are what we all know today. 27 00:01:48,974 --> 00:01:51,009 What we knew yesterday was different, 28 00:01:51,010 --> 00:01:52,878 and so were we. 29 00:01:52,879 --> 00:01:55,313 So that's why this series is also going to look at the past, 30 00:01:55,314 --> 00:01:57,381 at the way we were because of what we knew 31 00:01:57,382 --> 00:01:59,884 that was different from today 32 00:01:59,885 --> 00:02:01,886 and at how, through history, 33 00:02:01,887 --> 00:02:04,523 every time our view of the universe changed-- 34 00:02:04,524 --> 00:02:06,057 and us with it-- 35 00:02:06,058 --> 00:02:08,459 something was created that would help to make us 36 00:02:08,460 --> 00:02:10,829 the way we are in the modern world 37 00:02:10,830 --> 00:02:14,833 with the distinctive way of thinking that makes us us 38 00:02:14,834 --> 00:02:18,002 and not some other bunch with a different view. 39 00:02:26,412 --> 00:02:30,248 Not some other bunch thinking and acting differently, 40 00:02:30,249 --> 00:02:33,718 us, the end product of centuries of change 41 00:02:33,719 --> 00:02:36,120 that thinks it's the best there is, 42 00:02:36,121 --> 00:02:37,889 just like all the others do. 43 00:02:37,890 --> 00:02:41,325 Every group, nation, tribe, cult, ideology, 44 00:02:41,326 --> 00:02:45,029 each one certain of its version of the truth, 45 00:02:45,030 --> 00:02:48,500 prepared if necessary to defend that version to the death 46 00:02:48,501 --> 00:02:50,468 to keep it alive. 47 00:02:50,469 --> 00:02:51,603 And we are no different. 48 00:02:51,604 --> 00:02:54,706 We defend ours 1,000 feet down, 49 00:02:54,707 --> 00:02:58,843 here below me, under that mountain. 50 00:03:17,596 --> 00:03:20,331 It doesn't matter whether it's a hermetically sealed, 51 00:03:20,332 --> 00:03:23,534 radiation-proof, high-tech place like this 52 00:03:23,535 --> 00:03:27,104 or a stack of bows and arrows in a jungle hut. 53 00:03:27,105 --> 00:03:29,607 Every culture has one of these. 54 00:03:29,608 --> 00:03:34,212 It's where the truth is protected. 55 00:03:34,213 --> 00:03:37,582 This is what's meant by putting your money where your mouth is. 56 00:03:37,583 --> 00:03:40,284 It shows just how far you're prepared to go 57 00:03:40,285 --> 00:03:42,286 to defend your view of things. 58 00:03:42,287 --> 00:03:46,524 Here, as you can see, the attitude is quite far. 59 00:03:46,525 --> 00:03:48,659 It's the North American Air Defense Center 60 00:03:48,660 --> 00:03:50,929 inside Cheyenne Mountain. 61 00:03:58,771 --> 00:04:02,740 Any defense command center is where we define our boundaries, 62 00:04:02,741 --> 00:04:05,075 within which our view operates 63 00:04:05,076 --> 00:04:08,746 and across which any threatening movement will start a war. 64 00:04:08,747 --> 00:04:13,284 Here, those boundaries extend far beyond national frontiers. 65 00:04:13,285 --> 00:04:15,886 They reach out into space. 66 00:04:15,887 --> 00:04:17,755 If how right your view is 67 00:04:17,756 --> 00:04:20,525 can be measured by the territory you defend, 68 00:04:20,526 --> 00:04:23,894 then this global defense makes this view 69 00:04:23,895 --> 00:04:25,863 about as right as you can get. 70 00:04:25,864 --> 00:04:27,865 But then, we would think that, wouldn't we? 71 00:04:27,866 --> 00:04:33,070 So do all the others in their war rooms or jungle huts. 72 00:04:33,071 --> 00:04:34,806 And for everybody, 73 00:04:34,807 --> 00:04:37,375 the amount of effort you expend on defense 74 00:04:37,376 --> 00:04:41,011 enhances the value of your way of life. 75 00:04:41,012 --> 00:04:43,781 That effort here is maximal. 76 00:04:56,462 --> 00:04:59,030 A single multimegaton nuclear warhead 80 00:04:59,031 --> 00:05:00,698 would wipe this place out, 81 00:05:00,699 --> 00:05:03,067 and the Russians could put one through the front door 82 00:05:03,068 --> 00:05:04,602 if they tried. 83 00:05:04,603 --> 00:05:07,538 Should it come from an offshore submarine, 84 00:05:07,539 --> 00:05:09,807 its flight time will be 10 minutes, 85 00:05:09,808 --> 00:05:12,176 3 to identify it as incoming, 86 00:05:12,177 --> 00:05:14,312 7 to react, 87 00:05:14,313 --> 00:05:16,414 to get countermeasures off the ground 88 00:05:16,415 --> 00:05:19,350 to handle whatever else follows the missile. 89 00:05:19,351 --> 00:05:20,818 All over the Western World, 90 00:05:20,819 --> 00:05:23,888 military forces train for what they would have to do 91 00:05:23,889 --> 00:05:26,057 in those first 7 minutes. 92 00:05:26,058 --> 00:05:27,291 The numbers are massive, 93 00:05:27,292 --> 00:05:31,295 4 1/2 million troops, 25,000 battle tanks, 94 00:05:31,296 --> 00:05:33,031 over 11,000 aircraft, 95 00:05:33,032 --> 00:05:36,134 an unknown number of nuclear warheads. 96 00:05:36,135 --> 00:05:41,572 The Soviet Union test launches 500 missiles a year. 97 00:05:41,573 --> 00:05:42,807 The next one could be real. 98 00:05:42,808 --> 00:05:44,608 Readiness is unquestioning, 99 00:05:44,609 --> 00:05:46,611 the entire system poised to go 100 00:05:46,612 --> 00:05:48,513 perhaps for the first and last time 101 00:05:48,514 --> 00:05:51,282 in reaction to the words nobody wants to hear: 102 00:05:51,283 --> 00:05:52,283 unknown track. 103 00:05:55,153 --> 00:05:56,721 This is the command port. 105 00:05:56,722 --> 00:05:59,590 Prepare to copy and print the traffic for missile warning. 106 00:06:10,136 --> 00:06:12,103 I'll check, sir. 108 00:06:15,173 --> 00:06:18,009 Air Defense, operation center with an unknown track. 110 00:06:18,010 --> 00:06:19,877 Track number is Zulu 462. 111 00:06:19,878 --> 00:06:21,879 Time in all, 19-30-Zulu. 112 00:06:21,880 --> 00:06:23,815 Course, 1-3-0 degrees. 113 00:06:23,816 --> 00:06:25,382 Speed, 420 knots. 114 00:06:25,383 --> 00:06:27,418 Altitude, 28,000 feet. 115 00:06:27,419 --> 00:06:29,721 Identification, none. 116 00:06:29,722 --> 00:06:32,123 F-15s, scramble to time of 19-30-Zulu. 117 00:07:36,955 --> 00:07:40,758 So why are we so attached to being the way we are, 120 00:07:40,759 --> 00:07:42,093 so attached that all these people 121 00:07:42,094 --> 00:07:44,362 are prepared to die for it? 122 00:07:44,363 --> 00:07:46,664 Well, if you asked 9 out of 10 people in the West, 123 00:07:46,665 --> 00:07:49,667 they'd probably use the word "freedom", wouldn't they? 124 00:07:49,668 --> 00:07:51,802 Freedom of speech, freedom of movement, 125 00:07:51,803 --> 00:07:53,804 freedom of self-expression, 126 00:07:53,805 --> 00:07:58,475 or maybe "life, liberty, and the pursuit of happiness", 127 00:07:58,476 --> 00:08:02,079 that and the fact that we think our version of things 128 00:08:02,080 --> 00:08:04,015 is the best version there is. 129 00:08:04,016 --> 00:08:06,250 Look back as I'm going to in this series 130 00:08:06,251 --> 00:08:09,053 to the moments when what we were changed 131 00:08:09,054 --> 00:08:13,758 because what we knew changed, and you see how far we've come 132 00:08:13,759 --> 00:08:16,027 and also how each of those stages 133 00:08:16,028 --> 00:08:19,196 in the growth of our knowledge also brought into existence 134 00:08:19,197 --> 00:08:21,733 a vital bit of what it is we are today. 135 00:08:21,734 --> 00:08:23,267 Look. 136 00:08:31,610 --> 00:08:33,611 In 11th-century arab Spain, 137 00:08:33,612 --> 00:08:35,713 these christian crusaders made a discovery 138 00:08:35,714 --> 00:08:38,115 that led directly to the invention 139 00:08:38,116 --> 00:08:40,585 of the modern university degree. 140 00:08:54,867 --> 00:08:57,569 In 1420, we found a new way of painting 141 00:08:57,570 --> 00:08:59,504 that helped to give us in the modern world 142 00:08:59,505 --> 00:09:02,673 the ability to navigate our ships to a precise landfall 143 00:09:02,674 --> 00:09:05,809 anywhere on Earth or on another planet. 144 00:09:17,322 --> 00:09:18,522 Up to the 15th century, 147 00:09:18,523 --> 00:09:21,425 we memorized our knowledge in song or poetry. 148 00:09:21,426 --> 00:09:23,694 Then we invented a way to do without memory, 149 00:09:23,695 --> 00:09:24,962 and as a result, 150 00:09:24,963 --> 00:09:28,098 ushered in today's standardized technological existence. 151 00:09:39,344 --> 00:09:40,678 300 years ago, 154 00:09:40,679 --> 00:09:42,813 we believed the sky was made of crystal spheres. 155 00:09:42,814 --> 00:09:44,648 Then around 1600, 156 00:09:44,649 --> 00:09:47,185 these gunners destroyed that glass universe 157 00:09:47,186 --> 00:09:49,320 and triggered the beginnings of modern science. 158 00:09:56,662 --> 00:09:59,530 For centuries, we handcrafted everything we needed. 159 00:09:59,531 --> 00:10:01,499 Then an 18th-century religious misfit 160 00:10:01,500 --> 00:10:03,867 invented the power to move mountains 161 00:10:03,868 --> 00:10:06,203 and turned us all into compulsive consumers. 162 00:10:23,155 --> 00:10:25,756 The french revolutionary wars brought into existence 163 00:10:25,757 --> 00:10:27,190 an obsession with gambling 164 00:10:27,191 --> 00:10:29,727 that was to make every 20th-century western citizen 165 00:10:29,728 --> 00:10:33,297 a healthy, long-living number. 166 00:10:38,670 --> 00:10:41,005 In the 19th century came discoveries about nature 167 00:10:41,006 --> 00:10:42,973 that generated our belief ever since 168 00:10:42,974 --> 00:10:45,242 in the inevitability of progress. 169 00:10:56,021 --> 00:11:00,058 And in 1844 came the invention that would give us computers. 171 00:11:06,331 --> 00:11:08,198 So why did all that happen to us 173 00:11:08,199 --> 00:11:10,300 and not to the other cultures on the planet? 174 00:11:10,301 --> 00:11:12,837 Why did we keep on changing? 175 00:11:12,838 --> 00:11:15,505 Well, because of the kind of people we are. 176 00:11:15,506 --> 00:11:17,041 Let me try and show you what I mean. 177 00:11:17,042 --> 00:11:17,975 Look. 178 00:11:20,111 --> 00:11:21,579 You don't know what that is, do you? 179 00:11:21,580 --> 00:11:23,347 But you want to, don't you? 180 00:11:23,348 --> 00:11:26,016 Okay, I'll show you. 181 00:11:32,424 --> 00:11:33,791 That enough? 182 00:11:33,792 --> 00:11:35,026 No? 183 00:11:35,027 --> 00:11:37,094 Okay, try this. 184 00:11:46,070 --> 00:11:47,938 There, it's a lock. 185 00:11:47,939 --> 00:11:49,640 See? 186 00:11:49,641 --> 00:11:51,908 That's the kind of thing we do. 187 00:11:51,909 --> 00:11:55,012 We try to take the universe apart to see how it works. 188 00:11:55,013 --> 00:11:57,781 We can't leave anything alone without knowing what it is. 189 00:11:57,782 --> 00:12:00,484 We are insatiably curious, 190 00:12:00,485 --> 00:12:03,920 and that's what we defend here with all this military hardware, 191 00:12:03,921 --> 00:12:05,356 the right to be curious, 192 00:12:05,357 --> 00:12:07,824 to ask questions and get answers, 193 00:12:07,825 --> 00:12:10,227 to question authority and to remove it from power 194 00:12:10,228 --> 00:12:12,696 if we don't like what it's telling us. 195 00:12:12,697 --> 00:12:15,366 And that's why we've changed constantly throughout history 196 00:12:15,367 --> 00:12:17,201 to become what we are today, 197 00:12:17,202 --> 00:12:20,471 because we've never stopped asking questions. 198 00:12:20,472 --> 00:12:22,440 And what have we got as a result? 199 00:12:22,441 --> 00:12:26,477 Answers, a mountain of them gathered over the centuries, 200 00:12:26,478 --> 00:12:31,448 so much we've had to invent systems just to handle it; 201 00:12:31,449 --> 00:12:35,620 so big, information processing itself is now a science; 202 00:12:35,621 --> 00:12:39,456 so total, it's generated the full entire complex 203 00:12:39,457 --> 00:12:43,327 of the modern western world, a world based on information 204 00:12:43,328 --> 00:12:46,096 that we can defend from a hole inside a mountain 205 00:12:46,097 --> 00:12:48,532 thanks to the knowledge we've accumulated 206 00:12:48,533 --> 00:12:52,069 and that we want to go on being free to accumulate. 207 00:12:52,070 --> 00:12:55,673 So why are we so uniquely curious like that? 208 00:12:55,674 --> 00:12:58,909 Why did we first start asking questions, 209 00:12:58,910 --> 00:13:00,845 and why did we start... 210 00:13:00,846 --> 00:13:04,682 there? 211 00:13:17,529 --> 00:13:20,631 If, as I said earlier, we are what we know-- 214 00:13:20,632 --> 00:13:22,032 and we know a lot-- 215 00:13:22,033 --> 00:13:25,002 then we have Greece to thank for it. 216 00:13:53,698 --> 00:13:54,966 The western view of things 218 00:13:54,967 --> 00:13:57,801 varies a certain amount from one place to another, 219 00:13:57,802 --> 00:14:00,871 but basically it's a dynamic view we all share, 220 00:14:00,872 --> 00:14:03,774 a highly individualistic approach to things. 221 00:14:03,775 --> 00:14:05,776 And we all keep order in the same way 222 00:14:05,777 --> 00:14:07,444 with the same common beliefs 223 00:14:07,445 --> 00:14:09,479 and the understanding that to hold it all together, 224 00:14:09,480 --> 00:14:12,450 you have to compromise between doing your own thing 225 00:14:12,451 --> 00:14:15,853 and sticking to a minimal number of rules everybody agrees on 226 00:14:15,854 --> 00:14:18,389 if you're going to avoid chaos. 227 00:14:22,360 --> 00:14:24,629 If you landed here from another planet, 228 00:14:24,630 --> 00:14:26,763 came from another time, 229 00:14:26,764 --> 00:14:28,832 all this agreement, all the symbols, 230 00:14:28,833 --> 00:14:30,767 the way we all do what we do as a group, 231 00:14:30,768 --> 00:14:33,838 would be like a kind of message that you could read 232 00:14:33,839 --> 00:14:36,773 to find out what kind of civilization we are now. 233 00:14:36,774 --> 00:14:38,375 Because like everything else, 234 00:14:38,376 --> 00:14:42,412 this unspoken agreement is based on what we all know, 235 00:14:42,413 --> 00:14:44,448 and we're unique in the way we learn that. 236 00:14:44,449 --> 00:14:45,883 It's not genetic. 237 00:14:45,884 --> 00:14:47,584 You pick it up as you go along, 238 00:14:47,585 --> 00:14:49,686 the order things are supposed to be in, 239 00:14:49,687 --> 00:14:51,355 the way things are done. 240 00:14:51,356 --> 00:14:53,657 And when you get down to the individual level, 241 00:14:53,658 --> 00:14:55,659 the rules of the game are there too, 242 00:14:55,660 --> 00:14:57,360 much more subtle. 243 00:14:57,361 --> 00:14:59,797 But in spite of the fact that in one sense 244 00:14:59,798 --> 00:15:01,665 this is all greek to me, 245 00:15:01,666 --> 00:15:04,535 the agreements are so common to all of us in the West 246 00:15:04,536 --> 00:15:06,570 that wherever you're watching this from now, 247 00:15:06,571 --> 00:15:08,105 it'll make sense. 248 00:15:08,106 --> 00:15:09,907 Even if you don't speak the language, 249 00:15:09,908 --> 00:15:11,274 you know the code. 250 00:15:11,275 --> 00:15:12,209 Look. 251 00:15:58,890 --> 00:16:01,758 The way we are began on the coast of Turkey 252 00:16:01,759 --> 00:16:03,494 about 2,700 years ago 253 00:16:03,495 --> 00:16:06,530 with a group of Greeks looking for somewhere to settle 254 00:16:06,531 --> 00:16:08,932 after centuries of war and confusion 255 00:16:08,933 --> 00:16:11,869 had forced this particular lot to jump in their boats 256 00:16:11,870 --> 00:16:15,439 and head east for a bit of peace and quiet. 257 00:16:20,345 --> 00:16:22,813 Just as well these Ionians as they were called 258 00:16:22,814 --> 00:16:25,382 were a hardy, adventurous, pioneering lot, 259 00:16:25,383 --> 00:16:28,252 because they all fetched up in a part of the eastern Med 260 00:16:28,253 --> 00:16:31,188 not exactly known for its five-star accommodation. 261 00:16:31,189 --> 00:16:33,657 You could see that this wasn't going to be milk and honey, 262 00:16:33,658 --> 00:16:34,591 for instance. 263 00:16:34,592 --> 00:16:36,560 Everywhere they looked, it was the same story: 264 00:16:36,561 --> 00:16:40,564 mountains inland, hemming in a bit of scrubby coastal strip 265 00:16:40,565 --> 00:16:44,301 good for olives, wine, and getting out of. 266 00:16:44,302 --> 00:16:45,269 But since they had just arrived, 267 00:16:45,270 --> 00:16:47,604 the Ionians did the next best thing. 268 00:16:47,605 --> 00:16:49,406 They went into shipping. 269 00:16:49,407 --> 00:16:52,009 By 800 B.C., this intrepid lot 270 00:16:52,010 --> 00:16:54,478 had gone north to the russian steppes, 271 00:16:54,479 --> 00:16:57,347 south to the Sahara, west to the Atlantic, 272 00:16:57,348 --> 00:17:00,617 and their little ionian ships were like floating bazaars-- 273 00:17:00,618 --> 00:17:04,588 wine, oil, corn, silk, salt, millstones. 274 00:17:04,589 --> 00:17:07,691 You wanted it, they'd find it for you somewhere. 275 00:17:07,692 --> 00:17:09,660 Now, the thing about people like that 276 00:17:09,661 --> 00:17:12,296 is that they've always been after one thing above all else, 277 00:17:12,297 --> 00:17:13,530 haven't they? 278 00:17:13,531 --> 00:17:15,366 They're always looking for a better deal. 279 00:17:15,367 --> 00:17:16,867 Same with the Ionians. 280 00:17:16,868 --> 00:17:19,236 That's why they left Greece in the first place, 281 00:17:19,237 --> 00:17:22,273 and why, once ashore, in this inhospitable dump, 282 00:17:22,274 --> 00:17:23,774 they started doing something 283 00:17:23,775 --> 00:17:25,509 nobody else had ever done before. 284 00:17:28,814 --> 00:17:29,946 They started looking around 285 00:17:29,947 --> 00:17:33,583 to see what they could make of the place 286 00:17:33,584 --> 00:17:36,587 to make life a shade better than dreadful. 287 00:17:36,588 --> 00:17:39,823 Now, I know it sounds strange that I make such a big deal 288 00:17:39,824 --> 00:17:42,225 out of something that seems perfectly common sense-- 289 00:17:42,226 --> 00:17:44,327 taking a practical view of things-- 290 00:17:44,328 --> 00:17:48,231 but you have to remember that at the time, 3,000 years ago, 291 00:17:48,232 --> 00:17:52,036 the rest of the world was heavily into myths, gods, 292 00:17:52,037 --> 00:17:54,104 mysteries, and other views of nature 293 00:17:54,105 --> 00:17:56,674 not designed to tell you very much about the world around 294 00:17:56,675 --> 00:17:58,408 except that nature was none of your business. 295 00:18:03,514 --> 00:18:06,583 So when one of these Ionians, a guy called Thales, 296 00:18:06,584 --> 00:18:09,853 started asking practical questions about his environment, 297 00:18:09,854 --> 00:18:12,222 he was really breaking all the rules. 298 00:18:12,223 --> 00:18:14,558 Thales looked at nature with mechanisms in mind 299 00:18:14,559 --> 00:18:15,892 rather than magic, 300 00:18:15,893 --> 00:18:17,995 and he noticed how everything came in opposites: 301 00:18:17,996 --> 00:18:21,932 hot, cold; wet, dry; up, down-- opposites, 302 00:18:21,933 --> 00:18:24,301 just like the two sides of a deal, 303 00:18:24,302 --> 00:18:28,838 a crafty businesslike Ionian like Thales would have said. 304 00:18:28,839 --> 00:18:32,075 This business of opposite in nature and argument 305 00:18:32,076 --> 00:18:35,112 was to go meaningfully well with something else Thales did, 306 00:18:35,113 --> 00:18:39,984 which was to nip off to Egypt and bring back their geometry. 307 00:18:39,985 --> 00:18:43,520 Now, in the laid-back opulence of life up the Nile, 308 00:18:43,521 --> 00:18:44,754 where the local conditions 309 00:18:44,755 --> 00:18:47,057 produced the world's most regular good times, 310 00:18:47,058 --> 00:18:50,193 they lived kind of feet up and mind in neutral, 311 00:18:50,194 --> 00:18:51,361 so to speak. 312 00:18:51,362 --> 00:18:53,764 Problem solving was very much not their thing. 313 00:18:53,765 --> 00:18:56,166 So geometry got used for building pyramids 314 00:18:56,167 --> 00:18:59,469 and measuring land and nothing else. 315 00:18:59,470 --> 00:19:02,406 Thales, with practical needs in mind, 316 00:19:02,407 --> 00:19:04,408 tipped the pyramid on its side 317 00:19:04,409 --> 00:19:06,543 and used the triangle so that two people-- 318 00:19:06,544 --> 00:19:08,078 one here and here-- 319 00:19:08,079 --> 00:19:11,114 could get a cross bearing on a ship out at sea here 320 00:19:11,115 --> 00:19:14,151 and work out how far from land it was. 321 00:19:14,152 --> 00:19:15,252 Good, eh? 322 00:19:15,253 --> 00:19:18,788 But he did something much more clever. 323 00:19:18,789 --> 00:19:21,991 He took the circle, with its 360°, 324 00:19:21,992 --> 00:19:23,127 and halved it. 325 00:19:23,128 --> 00:19:26,330 So this line had to contain 180°, 326 00:19:26,331 --> 00:19:29,766 half the 360, right? 327 00:19:29,767 --> 00:19:31,601 Okay, try this. 328 00:19:31,602 --> 00:19:33,303 Here's a straight line. 329 00:19:33,304 --> 00:19:34,772 Here's another one. 330 00:19:34,773 --> 00:19:36,673 Now, these angles here and here 331 00:19:36,674 --> 00:19:38,475 must add up to 180, mustn't they? 332 00:19:38,476 --> 00:19:40,277 Let's call them "A" and "B". 333 00:19:40,278 --> 00:19:43,813 And these angles here and here add up to 180 too. 334 00:19:43,814 --> 00:19:46,216 Call them "B" and "C". 335 00:19:46,217 --> 00:19:51,155 Now, if "A" and "B" make 180 and "B" and "C" make 180, 336 00:19:51,156 --> 00:19:54,058 then "A" and "C" must be the same. 337 00:19:54,059 --> 00:19:55,959 Opposite angles are equal. 338 00:19:55,960 --> 00:19:58,395 From a self-evident thing like a circle, 339 00:19:58,396 --> 00:20:01,665 Thales had gone to a nonself-evident thing like this. 340 00:20:01,666 --> 00:20:03,267 That's the basis of geometry: 341 00:20:03,268 --> 00:20:06,937 going from something you know to discover something you don't. 342 00:20:06,938 --> 00:20:09,607 And all this was to turn out to go very well 343 00:20:09,608 --> 00:20:11,408 with that business of reconciling opposites 344 00:20:11,409 --> 00:20:12,409 I was on about, 345 00:20:12,410 --> 00:20:15,078 because by about 500 B.C., 346 00:20:15,079 --> 00:20:18,314 that's how they were running their cities. 347 00:20:21,920 --> 00:20:23,387 In the town squares, 348 00:20:23,388 --> 00:20:25,755 they'd settle things by the first ever public debates-- 349 00:20:25,756 --> 00:20:28,658 well, shouting matches-- called politics. 350 00:20:28,659 --> 00:20:31,561 And that kind of arguing opposite points of view 351 00:20:31,562 --> 00:20:33,930 plus their new geometry went together 352 00:20:33,931 --> 00:20:37,601 to produce an entirely original kind of structure for thinking 353 00:20:37,602 --> 00:20:40,470 with which you could tackle any subject. 354 00:20:40,471 --> 00:20:43,940 So being an adventurous lot, they did. 355 00:20:43,941 --> 00:20:48,144 The Greeks were into questions like, "What's it all made of? 356 00:20:48,145 --> 00:20:49,646 "Where did it all come from? 357 00:20:49,647 --> 00:20:52,816 and what's this constant change in nature all about?" 358 00:20:52,817 --> 00:20:54,485 And the technique they'd developed 359 00:20:54,486 --> 00:20:57,754 for reconciling opposites to reach political solutions 360 00:20:57,755 --> 00:21:00,557 was also a kind of way of thinking things through 361 00:21:00,558 --> 00:21:02,993 in general to reach new ideas, 362 00:21:02,994 --> 00:21:07,831 and so, in a physical sense, was the geometry, remember? 363 00:21:19,577 --> 00:21:24,080 Whatever happened in nature, lines and angles never changed. 364 00:21:24,081 --> 00:21:25,515 And that's where we began. 365 00:21:25,516 --> 00:21:29,353 I mean the rational way we in the west look at things. 366 00:21:29,354 --> 00:21:31,655 The rationalism that is the bringing together 367 00:21:31,656 --> 00:21:35,692 of logic and geometry, that's our way, 368 00:21:35,693 --> 00:21:37,761 driven since the questioning Greeks 369 00:21:37,762 --> 00:21:39,963 to look for the order in nature, 370 00:21:39,964 --> 00:21:43,067 without which there would be chaos. 371 00:22:13,531 --> 00:22:17,400 Today the rationalist greek way has brought us to the stage 374 00:22:17,401 --> 00:22:19,703 where our search for order, our questioning, 375 00:22:19,704 --> 00:22:23,373 reaches out even across the depths of intergalactic space. 376 00:22:29,113 --> 00:22:31,014 The answers we get from this antenna 377 00:22:31,015 --> 00:22:33,884 come from millions of light-years away, 378 00:22:33,885 --> 00:22:35,618 and if you look around here 379 00:22:35,619 --> 00:22:37,220 or wherever you are now, 380 00:22:37,221 --> 00:22:40,157 you see how the modern world is made up of answers, 381 00:22:40,158 --> 00:22:43,126 answers to questions in the past that were so good, 382 00:22:43,127 --> 00:22:45,062 we hung on to them. 383 00:22:54,906 --> 00:22:58,542 They are all around us, influencing the way we are. 384 00:23:00,845 --> 00:23:02,646 This is an 18th-century answer. 385 00:23:02,647 --> 00:23:05,682 I mean being able to build a gigantic metal structure 386 00:23:05,683 --> 00:23:07,384 like this radio telescope. 387 00:23:07,385 --> 00:23:10,587 Because the answer to a question being asked in the 18th century 388 00:23:10,588 --> 00:23:13,990 showed how to generate the power to make things like that. 389 00:23:15,560 --> 00:23:17,994 And when you can cut metal on an industrial scale, 390 00:23:17,995 --> 00:23:20,230 you can make machines on an industrial scale 391 00:23:20,231 --> 00:23:23,000 and manufacture on an industrial scale 392 00:23:23,001 --> 00:23:25,002 to solve the problems of a rising population. 393 00:23:31,375 --> 00:23:35,078 Steam power was the answer to that 18th century problem. 394 00:23:35,079 --> 00:23:37,314 They produced enough to feed themselves all right 395 00:23:37,315 --> 00:23:41,117 and, in doing so, started things we still live with: 396 00:23:41,118 --> 00:23:44,621 regular work for regular wages, factories and unions, 397 00:23:44,622 --> 00:23:47,224 the expectation of a steadily rising standard of living, 398 00:23:47,225 --> 00:23:48,958 and the problem of unemployment. 399 00:24:00,504 --> 00:24:04,507 The telescope here maps the sky. 400 00:24:04,508 --> 00:24:08,211 You feed in the coordinates, and it gives you that. 401 00:24:08,212 --> 00:24:11,581 It's a radio map of a galaxy 402 00:24:11,582 --> 00:24:16,320 2 million light-years straight out that way. 403 00:24:16,321 --> 00:24:18,588 This is a map of our galaxy. 404 00:24:18,589 --> 00:24:21,024 There's Andromeda. 405 00:24:21,025 --> 00:24:23,927 There's the galactic center. 406 00:24:23,928 --> 00:24:25,829 That use of coordinates 407 00:24:25,830 --> 00:24:29,132 to map the sky or where you live or anywhere 408 00:24:29,133 --> 00:24:32,736 is another answer we found and kept in the 15th century. 409 00:24:40,444 --> 00:24:41,979 Back then, the question was, 410 00:24:41,980 --> 00:24:44,547 how does the newly affluent florentine merchant 411 00:24:44,548 --> 00:24:47,451 get a bit of class into his life? 412 00:24:47,452 --> 00:24:48,585 The answer was to go to Greece 413 00:24:48,586 --> 00:24:50,487 and pick up some classical culture, 414 00:24:50,488 --> 00:24:51,954 which they did, 415 00:24:51,955 --> 00:24:55,358 together with an entirely new way of measuring things, 416 00:24:55,359 --> 00:24:57,661 things like the world, 417 00:24:57,662 --> 00:24:59,629 with a system that used gridlines, 418 00:24:59,630 --> 00:25:02,199 the kind of technique we use today for town planning 419 00:25:02,200 --> 00:25:04,400 or placing an intercontinental ballistic missile 420 00:25:04,401 --> 00:25:06,569 within 10 feet of its target. 421 00:25:09,507 --> 00:25:13,910 But we live with more than just physical answers from the past. 422 00:25:13,911 --> 00:25:18,582 When any good attitude or concept or system worked well, 423 00:25:18,583 --> 00:25:19,882 we hung on to it. 424 00:25:19,883 --> 00:25:22,552 We preserve representative democracy 425 00:25:22,553 --> 00:25:25,322 intended for a time when only a few could get to the capital 426 00:25:25,323 --> 00:25:26,956 to speak for the many. 427 00:25:26,957 --> 00:25:29,859 Modern finance was designed in the 17th century. 428 00:25:29,860 --> 00:25:31,928 Literacy as a test of intelligence 429 00:25:31,929 --> 00:25:33,930 came in the 15th century. 430 00:25:33,931 --> 00:25:37,401 The idea of progress is 19th century. 431 00:25:37,402 --> 00:25:38,569 And yet all those things 432 00:25:38,570 --> 00:25:41,004 are part of our mental furniture today, 433 00:25:41,005 --> 00:25:43,273 because when the answer to a question, 434 00:25:43,274 --> 00:25:45,842 a solution to a problem, suits us, 435 00:25:45,843 --> 00:25:47,643 we kind of institutionalize it 436 00:25:47,644 --> 00:25:50,446 so that it won't change even when we do. 437 00:25:50,447 --> 00:25:52,248 The business of questioning itself 438 00:25:52,249 --> 00:25:54,651 has been institutionalized like that 439 00:25:54,652 --> 00:25:58,555 in the kind of place Jodrell Bank Telescope belongs to: 440 00:25:58,556 --> 00:26:01,624 a university. 441 00:26:17,541 --> 00:26:19,542 If we are what we know, 443 00:26:19,543 --> 00:26:21,411 then this is where we pass on what we are 444 00:26:21,412 --> 00:26:22,713 to the next generation. 445 00:26:31,255 --> 00:26:32,688 And in the interest of safety, 446 00:26:32,689 --> 00:26:34,958 to keep the boat from being rocked too much, 447 00:26:34,959 --> 00:26:36,793 we teach the young to ask questions 448 00:26:36,794 --> 00:26:39,062 that have, in the main, already been answered. 449 00:26:39,063 --> 00:26:41,765 "Tristram Shandy asks us to help write the novel, 450 00:26:41,766 --> 00:26:44,667 but in so doing, we write ourselves." 451 00:26:44,668 --> 00:26:46,036 Good, I like that, 452 00:26:46,037 --> 00:26:51,140 particularly, I think, what you said about time. 453 00:26:51,141 --> 00:26:53,143 And to make sure we've passed on the view 454 00:26:53,144 --> 00:26:56,613 of how things are unmistakably, we test. 455 00:26:56,614 --> 00:26:58,682 After all, that's the only way you can be sure 456 00:26:58,683 --> 00:27:01,718 they know what they're supposed to know. 457 00:27:01,719 --> 00:27:04,854 And the system's worked well for hundreds of years. 458 00:27:04,855 --> 00:27:08,091 You can see how much we value this answer from the past 459 00:27:08,092 --> 00:27:11,261 in the way all education is conservative, cautious. 460 00:27:11,262 --> 00:27:14,064 It's as if we wanted to reassure ourselves 461 00:27:14,065 --> 00:27:15,064 that in the risky business 462 00:27:15,065 --> 00:27:17,234 of asking questions about knowledge, 463 00:27:17,235 --> 00:27:20,470 we were confidently operating with tried and tested ideas 464 00:27:20,471 --> 00:27:21,738 that hadn't failed us 465 00:27:21,739 --> 00:27:26,409 since when people dressed and talked like this. 466 00:27:26,410 --> 00:27:34,151 In nomine Domini, Patris, Filli, et Spiritus Sancti. 467 00:27:53,270 --> 00:27:54,604 The oldest answers 469 00:27:54,605 --> 00:27:56,872 to the most basic questions about how to operate 470 00:27:56,873 --> 00:27:59,876 are common to virtually every culture on the planet, 471 00:27:59,877 --> 00:28:01,378 because at the simplest level, 472 00:28:01,379 --> 00:28:03,814 every culture needs to keep order, 473 00:28:03,815 --> 00:28:06,583 especially this kind. 474 00:28:25,703 --> 00:28:27,971 This is one of the things in life we protect most 477 00:28:27,972 --> 00:28:30,907 against being changed when knowledge changes us. 478 00:28:30,908 --> 00:28:33,810 We protect it by turning it into a ritual. 479 00:28:43,587 --> 00:28:45,555 When you get married or buried, 481 00:28:45,556 --> 00:28:49,126 get christened or anything else too important to play by ear, 482 00:28:49,127 --> 00:28:51,428 the event is turned into a kind of play 483 00:28:51,429 --> 00:28:54,231 where everybody gets a role they act out. 484 00:28:54,232 --> 00:28:55,565 It's a kind of public agreement 485 00:28:55,566 --> 00:28:58,568 to stick to the general rules about whatever it is. 486 00:28:58,569 --> 00:29:02,272 The people doing it are effectively saying, 487 00:29:02,273 --> 00:29:04,974 "no matter what else may change, we won't rock the boat. 488 00:29:04,975 --> 00:29:06,443 "We're not maverick. 489 00:29:06,444 --> 00:29:08,345 you can trust us." 490 00:29:08,346 --> 00:29:10,547 Expressions of approval follow. 491 00:29:29,300 --> 00:29:32,435 Most of these ritual ways of answering a social need 494 00:29:32,436 --> 00:29:35,238 that we got from the past look like it. 495 00:29:35,239 --> 00:29:37,407 They include some thing from an ancient rite, 496 00:29:37,408 --> 00:29:40,176 in this case, the old symbol of fertility, 497 00:29:40,177 --> 00:29:41,178 the ring. 498 00:29:41,179 --> 00:29:42,412 And then it's all done 499 00:29:42,413 --> 00:29:45,649 in the presence of a supernatural being, a god. 500 00:29:45,650 --> 00:29:47,583 So the agreement is also made 501 00:29:47,584 --> 00:29:50,353 under what was once a real threat of heavenly retribution 502 00:29:50,354 --> 00:29:52,688 if you broke your promise later on. 503 00:29:52,689 --> 00:29:56,726 Some things, this ritual says, must be permanent. 504 00:30:13,377 --> 00:30:16,246 Rituals, if you like, permit change to happen, 507 00:30:16,247 --> 00:30:19,248 like the change in the status of the two people involved here. 508 00:30:19,249 --> 00:30:21,951 But it's change strictly by the book, 509 00:30:21,952 --> 00:30:26,189 ceremonial, formal, nerve-racking. 510 00:30:28,125 --> 00:30:30,293 "Phew", is usually the feeling at this point. 511 00:30:30,294 --> 00:30:31,961 Well, a ritual wouldn't be much of a ritual 512 00:30:31,962 --> 00:30:34,030 if you didn't feel you'd been put through the wringer, 513 00:30:34,031 --> 00:30:35,131 would it? 514 00:30:35,132 --> 00:30:37,233 So now it's official in every sense. 515 00:30:37,234 --> 00:30:40,102 The new order of things-- two are now one-- 516 00:30:40,103 --> 00:30:41,538 gets public recognition, 517 00:30:41,539 --> 00:30:44,608 and for just a few minutes, limited disorder is permitted. 518 00:30:48,813 --> 00:30:51,114 Mind you, most of the rituals in life 519 00:30:51,115 --> 00:30:52,581 don't involve a booze up. 520 00:30:52,582 --> 00:30:53,983 In most cases, 521 00:30:53,984 --> 00:30:56,753 if something becomes common enough to turn into a ritual 522 00:30:56,754 --> 00:31:00,189 and then starts to involve really large numbers of people, 523 00:31:00,190 --> 00:31:02,425 that's when the ritual becomes something else. 524 00:31:11,168 --> 00:31:12,368 It becomes widespread enough 525 00:31:12,369 --> 00:31:15,271 to affect that general agreement we all share. 526 00:31:15,272 --> 00:31:18,008 So that's when the responsibility for running it 527 00:31:18,009 --> 00:31:21,911 goes out of your hands 528 00:31:21,912 --> 00:31:24,714 to be taken over by the institutions set up 529 00:31:24,715 --> 00:31:28,284 to run the rituals that matter on a regular basis 530 00:31:28,285 --> 00:31:32,088 so that people can have clear rules and regulations to follow 531 00:31:32,089 --> 00:31:35,090 if they decide to get up to that particular ritual. 532 00:31:35,091 --> 00:31:38,795 The institutions take the admin out of daily life 533 00:31:38,796 --> 00:31:40,463 and run it for you: 534 00:31:40,464 --> 00:31:44,467 banking, government, sewage, tax collecting. 535 00:31:44,468 --> 00:31:47,637 Or if you break the rules and regulations, 536 00:31:47,638 --> 00:31:51,140 one institution can take you out of daily life: 537 00:31:51,141 --> 00:31:52,775 this one. 538 00:32:07,291 --> 00:32:09,492 In every community, the law, 539 00:32:09,493 --> 00:32:11,127 whether it's dressed up like this 540 00:32:11,128 --> 00:32:14,497 or the village elders telling you what the local custom is, 541 00:32:14,498 --> 00:32:18,567 the law is all those rules I was on about earlier. 542 00:32:28,645 --> 00:32:31,213 This may be double dutch to you, but you get the point. 545 00:32:35,819 --> 00:32:39,055 I suppose what institutions like this do most of all 547 00:32:39,056 --> 00:32:40,657 is the dirty work. 548 00:32:40,658 --> 00:32:42,958 While they're putting 'em away here in the law court, 549 00:32:42,959 --> 00:32:45,128 for instance, that leaves us free 550 00:32:45,129 --> 00:32:48,030 to get on with making money, having a career, 551 00:32:48,031 --> 00:32:50,266 and avoiding the social responsibility stuff 552 00:32:50,267 --> 00:32:52,369 these people have to deal with. 553 00:32:52,370 --> 00:32:55,238 And after a few centuries of this buck passing, 554 00:32:55,239 --> 00:32:57,740 the institutions get big and powerful 555 00:32:57,741 --> 00:33:00,176 and reach into everybody's life so much, 556 00:33:00,177 --> 00:33:02,045 they become hard to alter 557 00:33:02,046 --> 00:33:05,014 and virtually impossible to get rid of. 558 00:33:23,800 --> 00:33:25,401 The name of the game here 560 00:33:25,402 --> 00:33:28,371 and in all the institutions that run your life 561 00:33:28,372 --> 00:33:30,206 is keeping order, 562 00:33:30,207 --> 00:33:33,376 because if the institutions didn't do that, 563 00:33:33,377 --> 00:33:35,211 it would be the end of civilization as we know it, 564 00:33:35,212 --> 00:33:36,812 wouldn't it? 565 00:33:36,813 --> 00:33:40,716 So the institutions are usually old-fashioned, 566 00:33:40,717 --> 00:33:42,918 don't like change. 567 00:33:42,919 --> 00:33:46,021 Well, we all like to know where we stand, don't we? 568 00:33:46,022 --> 00:33:47,457 I mean, you wouldn't want this place 569 00:33:47,458 --> 00:33:50,125 to make up the rules as it went along, would you? 570 00:34:17,788 --> 00:34:20,990 The extreme way to protect yourself against change 573 00:34:20,991 --> 00:34:24,260 and keep total order in the face of awkward questions 574 00:34:24,261 --> 00:34:26,396 is to do it the way they do it in eastern communities, 575 00:34:26,397 --> 00:34:29,699 where, say, buddhism is a way of life. 576 00:34:29,700 --> 00:34:32,168 In that case, you're not bothered by questions 577 00:34:32,169 --> 00:34:33,769 because you're not looking for answers. 578 00:34:33,770 --> 00:34:37,306 Basically, all the answers a buddhist needs 579 00:34:37,307 --> 00:34:39,274 were found over 2,000 years ago. 580 00:34:39,275 --> 00:34:42,044 Their explanation of the universe is set 581 00:34:42,045 --> 00:34:44,747 in theological concrete, and in any case, 582 00:34:44,748 --> 00:34:47,150 it's a universe that doesn't change, 583 00:34:47,151 --> 00:34:49,619 so there's no need to go looking for change in it. 584 00:35:14,711 --> 00:35:17,179 The reason this culture is not like ours 585 00:35:17,180 --> 00:35:21,384 is because, like us, they are what they know. 586 00:35:21,385 --> 00:35:25,287 But since what they know doesn't change, they don't. 587 00:35:25,288 --> 00:35:27,656 The symbols and monuments that surround them 588 00:35:27,657 --> 00:35:29,658 are a part of their daily living. 589 00:35:30,894 --> 00:35:32,595 To our way of looking at it, 590 00:35:32,596 --> 00:35:35,598 they don't live with bits of the past affecting them; 591 00:35:35,599 --> 00:35:37,800 they live in the past. 592 00:35:49,246 --> 00:35:50,546 The nepalese way of life 593 00:35:50,547 --> 00:35:53,782 reflects their lack of interest in novelty. 594 00:35:53,783 --> 00:35:56,486 They don't change not because they're backward 595 00:35:56,487 --> 00:35:58,521 but because they don't want to. 596 00:35:58,522 --> 00:36:00,656 We, on the other hand, do. 597 00:36:00,657 --> 00:36:02,858 And that gives us a problem. 598 00:36:11,368 --> 00:36:15,738 In spite of the way institutions can act like a safety barrier 599 00:36:15,739 --> 00:36:17,573 against the effects of change, 600 00:36:17,574 --> 00:36:19,875 because of the way we've made asking questions 601 00:36:19,876 --> 00:36:21,243 one of our institutions, 602 00:36:21,244 --> 00:36:25,648 we do something that doesn't appear to make sense. 603 00:36:25,649 --> 00:36:28,051 Where other societies do things, 604 00:36:28,052 --> 00:36:31,621 organize themselves to keep things the way they are, 605 00:36:31,622 --> 00:36:35,658 we, because of our rationalist beginnings back in Greece, 606 00:36:35,659 --> 00:36:39,762 create places like this to do exactly the opposite, 607 00:36:39,763 --> 00:36:42,165 to make waves, to rock the boat, 608 00:36:42,166 --> 00:36:46,602 to ask questions knowing that the answers will change things. 609 00:36:46,603 --> 00:36:49,004 It's a scientific research lab. 610 00:36:49,005 --> 00:36:50,239 Through this inverter, 611 00:36:50,240 --> 00:36:52,942 which has to drive the signal up 612 00:36:52,943 --> 00:36:55,978 through about 5,000 microns of metal 613 00:36:55,979 --> 00:36:58,881 and about 2,000 of poly. 614 00:36:58,882 --> 00:37:00,816 Right here we had to get a cal-com. 615 00:37:00,817 --> 00:37:02,485 Difference between the modus simulation 616 00:37:02,486 --> 00:37:03,486 and the advice. 617 00:37:03,487 --> 00:37:04,920 Modus isn't quite as accurate. 618 00:37:04,921 --> 00:37:06,989 It will not latch this data in time. 619 00:37:06,990 --> 00:37:08,491 In places like this, 620 00:37:08,492 --> 00:37:11,427 we've institutionalized the business of change itself. 621 00:37:20,203 --> 00:37:21,738 And as for the other institutions, 622 00:37:21,739 --> 00:37:23,605 this kind has taken root 623 00:37:23,606 --> 00:37:26,642 ever since science first started affecting our daily lives. 624 00:37:28,879 --> 00:37:31,447 Today the mysterious world of the research lab 625 00:37:31,448 --> 00:37:34,016 comes up with so many answers so fast 626 00:37:34,017 --> 00:37:37,619 that only a few insiders know what the question was. 627 00:37:39,657 --> 00:37:42,558 If, as I said earlier, we are what we know, 628 00:37:42,559 --> 00:37:44,660 then this particular kind of institution 629 00:37:44,661 --> 00:37:47,996 spends its working hours finding ways to make things 630 00:37:47,997 --> 00:37:50,266 that will sooner or later change what we are, 631 00:37:50,267 --> 00:37:52,534 our view. 632 00:37:58,241 --> 00:38:02,010 Once, it took decades, even centuries for us to change. 633 00:38:02,011 --> 00:38:04,913 Now it could happen with every new discovery. 634 00:38:08,585 --> 00:38:12,154 But these places aren't just here to design fancy new gizmos. 635 00:38:12,155 --> 00:38:15,091 These semi-independent scientific communities 636 00:38:15,092 --> 00:38:16,725 spend as much of their effort involved 637 00:38:16,726 --> 00:38:19,329 in the kind of abstract theoretical thinking 638 00:38:19,330 --> 00:38:21,364 that may never have an application. 639 00:38:21,365 --> 00:38:23,532 But you never know. 640 00:38:25,669 --> 00:38:29,772 What they produce is ultimately approved by us or not 641 00:38:29,773 --> 00:38:31,674 when it gets onto the market. 642 00:38:31,675 --> 00:38:33,476 If what they make doesn't sell, 643 00:38:33,477 --> 00:38:35,578 then the kind of change it would have brought 644 00:38:35,579 --> 00:38:37,647 wasn't the kind of change we wanted. 645 00:38:37,648 --> 00:38:40,483 The problem is, we often don't know what they produce 646 00:38:40,484 --> 00:38:42,685 because it's not the kind of thing you'd know about 647 00:38:42,686 --> 00:38:45,254 unless you read scientific magazines. 648 00:38:49,192 --> 00:38:50,325 As often as not, 649 00:38:50,326 --> 00:38:52,061 the product changes the way we do things 650 00:38:52,062 --> 00:38:55,297 rather than the things themselves. 651 00:38:55,298 --> 00:38:58,300 They modify the world around us. 652 00:38:58,301 --> 00:38:59,969 Like you still go on using lifts; 653 00:38:59,970 --> 00:39:01,436 they just work differently. 654 00:39:01,437 --> 00:39:02,872 The buildings still go up; 655 00:39:02,873 --> 00:39:04,006 they're just built 656 00:39:04,007 --> 00:39:07,542 with different construction techniques. 657 00:39:09,780 --> 00:39:11,280 The phone looks just the same, 658 00:39:11,281 --> 00:39:14,384 only it does more things for you than it did before. 659 00:39:15,452 --> 00:39:17,019 Thanks to research labs like this, 660 00:39:17,020 --> 00:39:20,889 that kind of change happens every day, everywhere. 661 00:39:30,400 --> 00:39:32,101 Time to wake up. 665 00:39:48,485 --> 00:39:51,020 The point about all this technological pizzazz 668 00:39:51,021 --> 00:39:52,955 isn't the gee-whiz high-tech stuff. 669 00:39:52,956 --> 00:39:55,591 It's the secondary effects of using it. 670 00:39:55,592 --> 00:39:57,727 Take, say, what this chip could do 671 00:39:57,728 --> 00:39:59,762 to change the pattern of work. 672 00:39:59,763 --> 00:40:02,064 With this, you could have telecommuting. 673 00:40:02,065 --> 00:40:03,933 That's where you work at home from a screen, 674 00:40:03,934 --> 00:40:05,768 and you never go into the office. 675 00:40:05,769 --> 00:40:08,337 Great, no more rush hour. 676 00:40:08,338 --> 00:40:10,907 But what does that do to the public transportation system 677 00:40:10,908 --> 00:40:12,775 and the taxes it uses 678 00:40:12,776 --> 00:40:15,677 or to the car manufacturers and their workers' jobs 679 00:40:15,678 --> 00:40:18,347 and the rest of the economy that depends on their output 680 00:40:18,348 --> 00:40:20,616 or to the concept of the city itself 681 00:40:20,617 --> 00:40:23,418 with its support systems and businesses 682 00:40:23,419 --> 00:40:24,987 or to the downtown property values 683 00:40:24,988 --> 00:40:27,622 where maybe your pension fund's invested 684 00:40:27,623 --> 00:40:29,792 not to speak of working at home day in, day out 685 00:40:29,793 --> 00:40:32,128 and what that might do to a marriage? 686 00:40:32,129 --> 00:40:36,031 And what do you get out of work when it's only you? 687 00:40:36,032 --> 00:40:38,400 What would be the effect of isolating 688 00:40:38,401 --> 00:40:40,603 and fragmenting the community like that 689 00:40:40,604 --> 00:40:44,941 from just one application of this microchip? 690 00:40:47,310 --> 00:40:50,679 And every innovation modifies life like that, 691 00:40:50,680 --> 00:40:53,482 and our culture's been doing it for 1,000 years. 692 00:40:53,483 --> 00:40:56,585 That's the way we are, and it shows. 693 00:40:56,586 --> 00:41:00,223 Look at any western city, and you'll see a culture 694 00:41:00,224 --> 00:41:03,359 trying to come to terms with constant change. 695 00:41:09,099 --> 00:41:12,034 Look at the detail of your hometown 697 00:41:12,035 --> 00:41:13,269 or this place, 698 00:41:13,270 --> 00:41:16,205 and you see the way people saw things in the past 699 00:41:16,206 --> 00:41:19,608 and how different their views were to ours. 700 00:41:19,609 --> 00:41:21,577 You can still see those attitudes 701 00:41:21,578 --> 00:41:23,679 because of what they left behind them. 702 00:41:25,615 --> 00:41:27,750 Some of those past views lasted long enough 704 00:41:27,751 --> 00:41:29,484 and were so certain of themselves 705 00:41:29,485 --> 00:41:31,687 that they left behind really major bits of evidence 706 00:41:31,688 --> 00:41:33,188 of what they thought was important. 707 00:41:37,995 --> 00:41:39,561 Look at this for instance. 709 00:41:39,562 --> 00:41:44,233 19th-century San Francisco built churches 710 00:41:44,234 --> 00:41:46,168 and believed in heroes. 711 00:41:46,169 --> 00:41:49,638 How many statues do we build to honor great men today? 712 00:41:49,639 --> 00:41:51,541 And look at the public buildings of the period, 713 00:41:51,542 --> 00:41:53,809 almost imperial. 714 00:41:53,810 --> 00:41:56,278 And they obviously didn't think things were going to change much 715 00:41:56,279 --> 00:41:58,380 or they wouldn't have built like this, 716 00:41:58,381 --> 00:42:00,249 for a view that obviously thought 717 00:42:00,250 --> 00:42:03,285 it would last as long as the Greeks did. 718 00:42:03,286 --> 00:42:05,854 Today power lies with the quick fix, 719 00:42:05,855 --> 00:42:08,391 with the marketplace, and big business. 720 00:42:08,392 --> 00:42:10,926 And where once a home was a house, 721 00:42:10,927 --> 00:42:13,663 today it's a box in a skyscraper. 722 00:42:13,664 --> 00:42:17,232 We've gone from this way of looking at things to this 723 00:42:17,233 --> 00:42:19,201 in a generation. 724 00:42:58,608 --> 00:43:00,810 Now people work at night 727 00:43:00,811 --> 00:43:05,013 because somewhere else on the planet, it's not night. 728 00:43:05,014 --> 00:43:06,482 Train 238, Central. 729 00:43:06,483 --> 00:43:07,483 That's a 10-4. 730 00:43:07,484 --> 00:43:08,584 Your route is coming up. 731 00:43:08,585 --> 00:43:11,087 I'm receiving the-- the train now. 732 00:43:11,088 --> 00:43:13,022 Richmond train currently at Coliseum. 733 00:43:13,023 --> 00:43:14,924 The public transit system exists 734 00:43:14,925 --> 00:43:17,660 to deliver millions of people to their work every day 735 00:43:17,661 --> 00:43:20,128 like an extension of the production line process 736 00:43:20,129 --> 00:43:21,964 that runs the modern world 737 00:43:21,965 --> 00:43:23,531 and that everybody has to fit into 738 00:43:23,532 --> 00:43:26,167 and that changed the meaning of work 200 years ago 739 00:43:26,168 --> 00:43:27,903 when it first happened. 740 00:43:27,904 --> 00:43:30,806 Life, now, is working to buy this year's model 741 00:43:30,807 --> 00:43:33,809 because last year's is last year's. 742 00:43:33,810 --> 00:43:37,313 KFRC 743 00:43:37,314 --> 00:43:38,714 Good morning and welcome 744 00:43:38,715 --> 00:43:40,516 to the absolute ultimate radio program. 745 00:43:40,517 --> 00:43:43,652 And everywhere, freeways, expressways, throughways, 746 00:43:43,653 --> 00:43:46,889 all to make it easier for everybody to go places faster 747 00:43:46,890 --> 00:43:51,394 and in greater comfort than they were able to only yesterday. 748 00:43:51,395 --> 00:43:53,329 KFRC 749 00:43:53,330 --> 00:43:55,931 We live caught between more and more change 750 00:43:55,932 --> 00:43:59,168 and less and less time to adapt to it. 751 00:43:59,169 --> 00:44:02,004 We believe in the right of the individual to do his thing. 752 00:44:02,005 --> 00:44:03,238 But at the same time, 753 00:44:03,239 --> 00:44:07,376 we change what that thing is all the time. 754 00:44:11,214 --> 00:44:14,517 So this is what questioning has brought us. 756 00:44:14,518 --> 00:44:16,084 If we are what we know, 757 00:44:16,085 --> 00:44:18,153 then what we are in the modern West 758 00:44:18,154 --> 00:44:20,856 is unsure about how long it will be 759 00:44:20,857 --> 00:44:24,426 before what we know is out of date. 760 00:44:32,302 --> 00:44:34,803 You can see how a culture reveals itself 761 00:44:34,804 --> 00:44:36,372 by what it does. 762 00:44:36,373 --> 00:44:39,775 All that evidence about ours down there, 763 00:44:39,776 --> 00:44:41,677 you can read it like a book. 764 00:44:41,678 --> 00:44:43,345 And in our case, the message you get 765 00:44:43,346 --> 00:44:47,249 is that the only constant in life is change, 766 00:44:47,250 --> 00:44:49,685 not just in the physical shape of the world around, 767 00:44:49,686 --> 00:44:54,423 in standards, attitudes, ethics, values, morals, 768 00:44:54,424 --> 00:44:56,191 all shifting. 769 00:44:56,192 --> 00:44:57,759 The inevitable end product 770 00:44:57,760 --> 00:45:01,463 of that greek rationalism I talked about earlier 771 00:45:01,464 --> 00:45:02,798 is all around you. 772 00:45:02,799 --> 00:45:04,933 It's our world of here today and gone tomorrow. 773 00:45:14,143 --> 00:45:15,578 I said at the beginning 774 00:45:15,579 --> 00:45:19,248 all cultures think their view is worth defending to the death. 775 00:45:19,249 --> 00:45:23,252 But we more than most are split between yesterday and tomorrow, 776 00:45:23,253 --> 00:45:26,856 defending a way of life that is, by definition, 777 00:45:26,857 --> 00:45:28,590 a question mark. 778 00:46:04,560 --> 00:46:07,629 So here we are, committed by our greek origins 782 00:46:07,630 --> 00:46:10,766 to a life of asking questions that provide answers 783 00:46:10,767 --> 00:46:13,202 that turn out to create more questions 784 00:46:13,203 --> 00:46:15,370 and no end in sight. 785 00:46:15,371 --> 00:46:18,440 And as our amazing abilities grow more amazing, 786 00:46:18,441 --> 00:46:19,975 the more questions we ask, 787 00:46:19,976 --> 00:46:21,276 we're reaching the stage 788 00:46:21,277 --> 00:46:23,512 where it's not a matter of what novelty of change 789 00:46:23,513 --> 00:46:25,214 the future will bring next 790 00:46:25,215 --> 00:46:29,451 but what kind of future we care to invent, make happen. 791 00:46:29,452 --> 00:46:32,321 We can make deserts bloom or make deserts, 792 00:46:32,322 --> 00:46:35,624 move mountains, maybe create life, 793 00:46:35,625 --> 00:46:38,994 all because we can't leave things alone. 794 00:46:47,537 --> 00:46:50,005 But why do we go on asking questions? 795 00:46:50,006 --> 00:46:53,008 If the only point has ever been to find the right answer, 796 00:46:53,009 --> 00:46:54,910 to explain all this lot, 797 00:46:54,911 --> 00:46:57,179 what was wrong with the one the Greeks found? 798 00:46:57,180 --> 00:47:00,015 Why didn't we stick with their view of the universe 799 00:47:00,016 --> 00:47:01,116 or any of the other views 800 00:47:01,117 --> 00:47:02,651 that have come along since the Greeks? 801 00:47:02,652 --> 00:47:05,221 Why didn't we stick with one of them? 802 00:47:05,222 --> 00:47:07,355 Well, in a sense, we did. 803 00:47:07,356 --> 00:47:11,894 Part of the way we view things now does come from the past. 804 00:47:11,895 --> 00:47:14,763 Many of the institutions and attitudes we have 805 00:47:14,764 --> 00:47:16,231 originated in the past, 806 00:47:16,232 --> 00:47:19,134 born of different answers to different questions 807 00:47:19,135 --> 00:47:22,070 in different times with different problems. 808 00:47:22,071 --> 00:47:25,007 But they continue to exist, still operate, 809 00:47:25,008 --> 00:47:27,042 modified but basically the same, 810 00:47:27,043 --> 00:47:31,346 still affecting us like living fossils. 811 00:47:31,347 --> 00:47:33,916 Even in a world of constant change like ours, 812 00:47:33,917 --> 00:47:36,351 many of those systems that control, 813 00:47:36,352 --> 00:47:38,020 organize our view of things 814 00:47:38,021 --> 00:47:41,924 and the way we do what we do are outdated. 815 00:47:41,925 --> 00:47:44,026 So why do we keep them? 816 00:47:46,396 --> 00:47:49,431 Well, that's also what this series is going to look at: 817 00:47:49,432 --> 00:47:51,066 the changes in knowledge 818 00:47:51,067 --> 00:47:53,636 that brought them into existence in the first place, 819 00:47:53,637 --> 00:47:55,638 the problems they were designed to solve, 820 00:47:55,639 --> 00:47:59,041 and the way they made us what we are today. 821 00:47:59,042 --> 00:48:01,476 It was the earliest of those changes in the past, 822 00:48:01,477 --> 00:48:02,610 the one that gave birth 823 00:48:02,611 --> 00:48:04,646 to one of the most powerful institutions 824 00:48:04,647 --> 00:48:06,015 in the modern world, 825 00:48:06,016 --> 00:48:09,885 that I want to look at first in the next program, 826 00:48:09,886 --> 00:48:12,487 because the knowledge generated then 827 00:48:12,488 --> 00:48:15,257 gave us the idea basic to life ever since: 828 00:48:15,258 --> 00:48:17,660 that we could shape the future. 829 00:48:17,661 --> 00:48:21,163 That change I'm talking about happened, oh, 830 00:48:21,164 --> 00:48:25,801 900 years ago in Spain almost by accident. 831 00:48:25,802 --> 00:48:27,035 And funnily enough, 832 00:48:27,036 --> 00:48:28,670 given the fact that it made us all think 833 00:48:28,671 --> 00:48:30,906 that we could shape the future-- 834 00:48:30,907 --> 00:48:33,408 and I'll leave you with this thought till next time-- 835 00:48:33,409 --> 00:48:37,145 it actually involved people looking in crystal balls.
