0:00:00.000,0:00:01.006 0:00:01.006,0:00:01.031 PROFESSOR: OK. 0:00:01.031,0:00:05.005 So the clicker question that[br]I want to ask you right now 0:00:05.005,0:00:07.058 is--ah, shoot! 0:00:07.058,0:00:08.054 This says polling closed. 0:00:08.054,0:00:09.056 Now polling open. 0:00:09.056,0:00:13.077 "Did you commit to turning[br]off the internet 0:00:13.077,0:00:15.066 completely?", press one. 0:00:15.066,0:00:18.016 "Did you commit to restricting[br]your internet usage in some 0:00:18.016,0:00:20.017 way?" That is, you're keeping[br]the internet on, but you're 0:00:20.017,0:00:23.445 promising not to check Facebook,[br]or play Angry Birds, 0:00:23.445,0:00:28.006 or go shopping at Zappos, or[br]whatever other indulgent thing 0:00:28.006,0:00:29.058 you do on the internet. 0:00:29.058,0:00:31.071 If that's your case,[br]press two. 0:00:31.071,0:00:35.036 "Did you put no restriction on[br]your in-class internet use, 0:00:35.036,0:00:38.042 but you're somebody with a[br]computer?" If so, press three. 0:00:38.042,0:00:41.013 Or is it kind of not applicable[br]to you, because 0:00:41.013,0:00:44.076 you're somebody who uses a[br]pencil and paper in class? 0:00:44.076,0:00:45.021 OK. 0:00:45.021,0:00:47.006 Now it's supposed to be the[br]case that the timer is 0:00:47.006,0:00:50.068 counting itself down, but no,[br]I've got to prattle for 0:00:50.068,0:00:52.001 twenty-eight seconds. 0:00:52.001,0:00:53.005 So here we go. 0:00:53.005,0:00:57.088 So this is a case--I read[br]through the papers for my 0:00:57.088,0:01:00.022 section, and my sense there--and[br]I don't know 0:01:00.022,0:01:02.087 whether it was a random[br]sample--is that about 0:01:02.087,0:01:05.037 two-thirds of the students[br]committed to totally turning 0:01:05.037,0:01:09.092 off the internet, and about a[br]quarter committed to sometimes 0:01:09.092,0:01:13.062 restriction, and a very small[br]percentage committed to no 0:01:13.062,0:01:15.034 restriction on internet use. 0:01:15.034,0:01:15.066 OK. 0:01:15.066,0:01:19.074 It should be the case in one[br]second that our slide-- 0:01:19.074,0:01:20.039 yes. 0:01:20.039,0:01:20.071 OK. 0:01:20.071,0:01:26.084 So 43% of you, 43% of the[br]students in this room, made a 0:01:26.084,0:01:30.062 precommitment in the[br]form of a promise. 0:01:30.062,0:01:33.042 It became a precommitment[br]because you wrote it down. 0:01:33.042,0:01:35.062 Just thinking it didn't[br]make a precommitment. 0:01:35.062,0:01:40.016 But you took an action at a time[br]when you felt yourself to 0:01:40.016,0:01:45.106 be cool and calm and reasonable,[br]and made a 0:01:45.106,0:01:49.004 decision at that moment that[br]you took to be binding upon 0:01:49.004,0:01:51.023 yourself in the future. 0:01:51.023,0:01:56.029 And an additional 16% of you[br]didn't draw a bright line at 0:01:56.029,0:01:59.079 the turning off internet[br]completely, but attempted to 0:01:59.079,0:02:04.008 put in place some sort of[br]intermediate restriction. 0:02:04.008,0:02:10.002 Now my next question for you is[br]whether you have strayed. 0:02:10.002,0:02:10.096 Twenty seconds. "One. 0:02:10.096,0:02:12.037 Not even an itty bitty bit. 0:02:12.037,0:02:14.003 Not once." "Two. 0:02:14.003,0:02:16.013 Just once or twice." "Three. 0:02:16.013,0:02:21.637 Um, well, a few times, but I'm[br]trying." Or "four, yep, I've 0:02:21.637,0:02:29.034 been playing Sparkle HD Lite[br]on my iPad all class long." 0:02:29.034,0:02:32.006 And let's see how the[br]numbers came out. 0:02:32.006,0:02:32.094 OK. 0:02:32.094,0:02:36.006 So we should get--that didn't[br]show up automatically. 0:02:36.006,0:02:36.924 Aha. 0:02:36.924,0:02:40.027 So 56% of you-- 0:02:40.027,0:02:41.016 excellent. 0:02:41.016,0:02:43.665 56% of you have not[br]strayed at all. 0:02:43.665,0:02:49.092 But notice that half of you have[br]found ourselves unable to 0:02:49.092,0:02:53.083 carry through with a commitment[br]that you made, and 0:02:53.083,0:02:57.076 that you provided some[br]enforcement for in the sense 0:02:57.076,0:03:02.063 that you internalized in your[br]conscience the idea that you 0:03:02.063,0:03:05.624 had made a commitment. 0:03:05.624,0:03:09.008 It turns out that for many[br]people, simply making a 0:03:09.008,0:03:15.086 commitment in their mind is[br]insufficient for them to stay 0:03:15.086,0:03:20.092 in this not even an itty[br]bitty bit category. 0:03:20.092,0:03:27.093 For those people, who end up[br]here or here or even here, it 0:03:27.093,0:03:29.088 turns out that putting some sort[br]of external constraints 0:03:29.088,0:03:32.013 in place are useful. 0:03:32.013,0:03:35.024 So the New York Times had[br]a piece last week about 0:03:35.024,0:03:40.678 something called Phone Condom,[br]whose slogan is "Zip it, lock 0:03:40.678,0:03:45.048 it, keep it in your pocket." And[br]the idea is that you take 0:03:45.048,0:03:49.047 your cell phone, and you put it[br]in this little Ziploc bag, 0:03:49.047,0:03:52.091 and while you're driving,[br]you are unable to 0:03:52.091,0:03:55.056 gain access to it. 0:03:55.056,0:03:58.044 One of the students in this[br]class--and you'll have access 0:03:58.044,0:04:01.093 to this on the slide--e-mailed[br]me a link to a computer 0:04:01.093,0:04:05.064 program which is basically a[br]computer condom, a "zip it, 0:04:05.064,0:04:08.047 lock it, keep it in your pocket"[br]for internet access. 0:04:08.047,0:04:12.385 It turns off access to[br]the internet for a 0:04:12.385,0:04:15.201 given period of time. 0:04:15.201,0:04:18.042 But for those of you who feel[br]like you want some sort of 0:04:18.042,0:04:22.083 external reinforcement, but[br]you're not prepared to make 0:04:22.083,0:04:27.005 use of the internet lockup, I[br]thought I'd provide something 0:04:27.005,0:04:32.069 which would help you stick to[br]your commitment by making use 0:04:32.069,0:04:37.032 of two things that we learned[br]about last week. 0:04:37.032,0:04:42.425 One is that when there are eyes[br]in front of you, you feel 0:04:42.425,0:04:45.076 the gaze of the world[br]upon you. 0:04:45.076,0:04:48.023 And the other is that when[br]there's a kind of social 0:04:48.023,0:04:53.041 reinforcement by peers, it's[br]easier to stick with a plan. 0:04:53.041,0:04:57.073 So not only because they are[br]left over from my older son's 0:04:57.073,0:05:03.004 bar mitzvah, I have for you[br]smiley face stickers, which 0:05:03.004,0:05:04.068 the TFs will hand out. 0:05:04.068,0:05:08.724 And if you would like, you are[br]free to put a red or orange 0:05:08.724,0:05:11.039 sticker on the corner of your[br]computer if you're committed 0:05:11.039,0:05:12.097 to no internet during class. 0:05:12.097,0:05:15.996 It'll be there to remind you[br]and to show your peers. 0:05:15.996,0:05:19.044 And a green or blue sticker on[br]your computer if you are 0:05:19.044,0:05:22.068 committed to restricted[br]internet during class. 0:05:22.068,0:05:25.084 To the TFs, there are 720 of[br]these stickers, so we're not 0:05:25.084,0:05:26.004 going to run out. 0:05:26.004,0:05:28.416 You can just hand out-- 0:05:28.416,0:05:31.015 just hand them out, a little[br]piece of them, and people can 0:05:31.015,0:05:33.078 pass them around, and put[br]them there or not. 0:05:33.078,0:05:34.086 We're no worse off. 0:05:34.086,0:05:37.041 They were sitting on my desk[br]since the bar mitzvah, which 0:05:37.041,0:05:40.075 was in October, and I thought,[br]here, we can make four points 0:05:40.075,0:05:42.002 at once in a class. 0:05:42.002,0:05:44.068 In fact, we can make five. 0:05:44.068,0:05:49.004 Because the question of[br]self-regulation is, in fact, 0:05:49.004,0:05:53.049 the fundamental question that[br]we are addressing in the 0:05:53.049,0:05:57.006 context of the material that[br]we read for today. 0:05:57.006,0:06:01.002 So I want to apologize, because[br]today's lecture really 0:06:01.002,0:06:04.087 is, in lots of ways, dead[br]guys on Tuesday. 0:06:04.087,0:06:08.056 I'm going to go through, in some[br]detail, some arguments 0:06:08.056,0:06:11.018 from Plato, and then in[br]some detail, some 0:06:11.018,0:06:12.076 arguments from Aristotle. 0:06:12.076,0:06:16.081 But my hope is that by doing[br]so, I'll provide you with a 0:06:16.081,0:06:19.027 framework that will allow you,[br]when you go back to the 0:06:19.027,0:06:21.057 reading, perhaps in the context[br]of writing your 0:06:21.057,0:06:27.006 papers, to feel like those texts[br]have become accessible. 0:06:27.006,0:06:32.062 So famously, as you recall,[br]Plato had suggested that our 0:06:32.062,0:06:37.056 soul can be understood as[br]having three parts. 0:06:37.056,0:06:41.086 That we have a rational part,[br]which he represents sometimes 0:06:41.086,0:06:45.022 as a human being, sometimes[br]as a charioteer. 0:06:45.022,0:06:48.018 That we have one called the[br]spirited part, which he 0:06:48.018,0:06:51.002 represents sometimes as[br]a cooperative horse, 0:06:51.002,0:06:52.064 sometimes as a lion. 0:06:52.064,0:06:55.093 And that we have, in addition,[br]an appetitive part, which he 0:06:55.093,0:06:59.077 represents sometimes as a wild[br]horse, and sometimes as a 0:06:59.077,0:07:01.077 multiheaded beast. 0:07:01.077,0:07:08.068 Plato's suggestion is that a[br]certain kind of happiness is 0:07:08.068,0:07:13.039 available to us if we get[br]these parts into line. 0:07:13.039,0:07:17.048 He writes, "one is just who[br]does not allow the various 0:07:17.048,0:07:21.017 parts within him to meddle[br]with each other. 0:07:21.017,0:07:25.165 He regulates well what is his[br]own, and rules himself, puts 0:07:25.165,0:07:29.033 himself in order, and harmonizes[br]the three parts of 0:07:29.033,0:07:33.126 himself like three limiting[br]notes on a musical scale. 0:07:33.126,0:07:36.985 And from having been many[br]things"-- from having been as 0:07:36.985,0:07:41.007 you are, pulled in two[br]directions, pulled in the 0:07:41.007,0:07:44.004 direction of keeping the[br]internet off, and pulled in 0:07:44.004,0:07:47.098 the direction of checking[br]your Facebook page. 0:07:47.098,0:07:50.096 Pulled in the direction of going[br]to the library and doing 0:07:50.096,0:07:53.079 your homework, and pulled in the[br]direction of hanging out 0:07:53.079,0:07:56.018 your suite and talking[br]to your suitemate. 0:07:56.018,0:07:59.035 "From having been many[br]things"--pulled in the 0:07:59.035,0:08:02.087 direction of what reason tells[br]you to do, and pulled in the 0:08:02.087,0:08:06.065 direction of what spirit or[br]appetite tells you to do--"you 0:08:06.065,0:08:11.012 become entirely one, moderate[br]and harmonious." 0:08:11.012,0:08:16.074 So the Platonic ideal of the[br]well-structured soul is one 0:08:16.074,0:08:23.038 regulated by reason in which[br]spirit and appetite are 0:08:23.038,0:08:27.079 subjected to reason's[br]mandates. 0:08:27.079,0:08:30.002 Now, what I want to[br]give you now is 0:08:30.002,0:08:32.028 basically a thirty second-- 0:08:32.028,0:08:34.041 well, five minute-- 0:08:34.041,0:08:39.093 overview of the plot of Plato's[br]Republic in Books, 0:08:39.093,0:08:42.078 (sort of), II, III,[br]IV, and IX. 0:08:42.078,0:08:43.062 OK? 0:08:43.062,0:08:45.765 So the story goes as follows. 0:08:45.765,0:08:50.023 Plato is trying to tell us what[br]the human soul is like. 0:08:50.023,0:08:52.085 And in honor of the weather,[br]we'll represent the human 0:08:52.085,0:08:55.212 being like this. 0:08:55.212,0:08:58.071 And he points out, as I just[br]noted, that the human soul has 0:08:58.071,0:08:59.008 three parts. 0:08:59.008,0:09:04.012 It's got a rational part, it's[br]got a spirited in part, and 0:09:04.012,0:09:08.002 it's got a part that is full[br]of appetite, appetitive. 0:09:08.002,0:09:11.036 And you can see the human[br]being, the lion, and the 0:09:11.036,0:09:15.023 multiheaded beast, in Plato's[br]famous image there. 0:09:15.023,0:09:19.094 But in order to understand what[br]is good for the human 0:09:19.094,0:09:24.073 being, Socrates suggests, at the[br]end of the discussion in 0:09:24.073,0:09:29.345 book two, which we read for last[br]class, that the best way 0:09:29.345,0:09:33.054 to understand what it is that's[br]good for the tripartite 0:09:33.054,0:09:38.091 human being is to think about[br]what would be good for a city 0:09:38.091,0:09:41.007 that is structured[br]in the same way. 0:09:41.007,0:09:46.095 What societal structures can[br]help us understand things 0:09:46.095,0:09:49.666 about the internal structures[br]of human beings? 0:09:49.666,0:09:56.051 So he proposes the famous[br]city-state analogy, whereby 0:09:56.051,0:09:58.085 corresponding to the part of[br]the soul that he calls 0:09:58.085,0:10:07.003 appetite are citizens of the[br]city that he calls workers, or 0:10:07.003,0:10:12.009 people who do the day-to-day[br]work of the city, and who take 0:10:12.009,0:10:17.029 their joy and pleasure from the[br]pleasures of the body and 0:10:17.029,0:10:18.096 of the appetite. 0:10:18.096,0:10:26.003 There are soldiers, those who[br]defend the city and serve as 0:10:26.003,0:10:30.007 its defenders in military[br]context, that who are 0:10:30.007,0:10:32.074 motivated by honor. 0:10:32.074,0:10:39.048 And there are, in addition,[br]philosophers or guardians, 0:10:39.048,0:10:42.099 those who live the[br]life of the mind. 0:10:42.099,0:10:45.000 And you'll notice who[br]gets to end up at 0:10:45.000,0:10:47.844 the top in this story. 0:10:47.844,0:10:53.049 So the idea is that in order[br]to understand the four 0:10:53.049,0:10:59.024 cardinal virtues in the context[br]of the individual, we 0:10:59.024,0:11:04.525 will be helped by thinking about[br]where those virtues can 0:11:04.525,0:11:07.036 be found in the city. 0:11:07.036,0:11:11.051 And we can then map what it[br]is that we've learned from 0:11:11.051,0:11:14.045 looking at the problem[br]writ large in 0:11:14.045,0:11:16.006 the context of society. 0:11:16.006,0:11:20.082 We can map that onto what[br]would be the case in the 0:11:20.082,0:11:25.008 context of the problem writ[br]small, the individual. 0:11:25.008,0:11:30.028 So Plato's Socrates points out[br]that there are four cardinal 0:11:30.028,0:11:32.094 virtues, and you know these[br]from your reading. 0:11:32.094,0:11:35.085 The first of these is wisdom. 0:11:35.085,0:11:39.072 And the wisdom of the city and[br]of the individual is to be 0:11:39.072,0:11:43.007 found in its rational part. 0:11:43.007,0:11:43.034 OK. 0:11:43.034,0:11:44.059 Those should be-- 0:11:44.059,0:11:50.054 0:11:50.054,0:11:53.062 There is courage. 0:11:53.062,0:11:57.005 And the courage of a city or[br]of an individual is to be 0:11:57.005,0:12:01.003 found in its spirited parts. 0:12:01.003,0:12:03.054 They're dancing. 0:12:03.054,0:12:07.004 And there are two virtues--the[br]distinction between which is 0:12:07.004,0:12:11.025 important in some contexts, but[br]not for ours--and those 0:12:11.025,0:12:14.071 are the virtues of moderation[br]and justice. 0:12:14.071,0:12:19.003 And the suggestion here is[br]that just as a city is 0:12:19.003,0:12:23.036 moderate and just when the[br]relations among the people in 0:12:23.036,0:12:28.043 it are proper, so, too, is an[br]individual moderate or just 0:12:28.043,0:12:32.006 when the relations among[br]its part are 0:12:32.006,0:12:34.072 appropriate and proper. 0:12:34.072,0:12:38.062 That is, moderation and justice[br]involve a certain kind 0:12:38.062,0:12:43.001 of harmony among the parts. 0:12:43.001,0:12:46.019 So that's the Platonic[br]picture. 0:12:46.019,0:12:51.093 And it turns out that this[br]is Plato's answer-- 0:12:51.093,0:12:54.002 Plato's answer in the[br]voice of Socrates-- 0:12:54.002,0:12:58.095 to the challenge that Glaucon[br]posed to us in 0:12:58.095,0:13:01.004 middle of book two. 0:13:01.004,0:13:04.062 You remember that we were given,[br]at the beginning of 0:13:04.062,0:13:08.097 book two, a three-way[br]distinction among goods. 0:13:08.097,0:13:11.072 We were told that there were[br]things that are valuable 0:13:11.072,0:13:15.023 intrinsically, in themselves. 0:13:15.023,0:13:18.062 There are things that are[br]valuable instrumentally, for 0:13:18.062,0:13:21.003 the goods that they provide[br]beyond themselves. 0:13:21.003,0:13:24.009 Those are things like money,[br]which have no intrinsic value, 0:13:24.009,0:13:27.066 but which have instrumental[br]worth. 0:13:27.066,0:13:29.098 And that there are things[br]that are valuable both 0:13:29.098,0:13:33.024 intrinsically and[br]instrumentally. 0:13:33.024,0:13:38.062 And you recall that Glaucon's[br]argument, first with the claim 0:13:38.062,0:13:42.205 that when we talk about justice,[br]we make claims for 0:13:42.205,0:13:46.087 its benefit in terms of the[br]goods that it provides in 0:13:46.087,0:13:48.015 reputation. 0:13:48.015,0:13:52.014 Second in his Ring of Gyges[br]story, where he argued that if 0:13:52.014,0:13:55.057 we can get away with acting[br]unjustly, we should do so. 0:13:55.057,0:13:59.001 And third, in the story of[br]what's called the statues 0:13:59.001,0:14:03.008 scrubbed, or the inverted[br]story, that even if you 0:14:03.008,0:14:08.006 weren't convinced by the Gyges[br]story, surely if justice 0:14:08.006,0:14:11.061 produced a bad reputation, and[br]injustice a good one, that you 0:14:11.061,0:14:14.004 would want to act unjustly. 0:14:14.004,0:14:19.033 So those three arguments are[br]Glaucon's arguments in favor 0:14:19.033,0:14:25.011 of justice being something with[br]only instrumental value. 0:14:25.011,0:14:31.906 On his picture, justice is[br]something that is of utility 0:14:31.906,0:14:35.093 to us in a way that money[br]is of utility to us. 0:14:35.093,0:14:41.086 It can help us buy our way into[br]things that themselves 0:14:41.086,0:14:45.072 have intrinsic value. 0:14:45.072,0:14:49.027 Socrates' argument, by contrast,[br]is that justice is 0:14:49.027,0:14:53.002 something with both of these[br]characteristics. 0:14:53.002,0:14:56.036 No doubt it is of instrumental[br]utility. 0:14:56.036,0:14:59.085 He doesn't deny either Glaucon's[br]arguments or 0:14:59.085,0:15:03.079 Adeimantus's arguments about[br]the ways in which being 0:15:03.079,0:15:08.066 perceived as just can[br]be of use to us. 0:15:08.066,0:15:12.039 But in addition, he argues[br]that there is a certain 0:15:12.039,0:15:17.016 intrinsic worth associated[br]with having one's soul 0:15:17.016,0:15:21.016 structured in the way that[br]the just soul is. 0:15:21.016,0:15:24.072 Now, I want to point out to you,[br]to be fair to Glaucon and 0:15:24.072,0:15:28.032 Adeimantus, that there's[br]a bit of a cheat here. 0:15:28.032,0:15:31.049 Glaucon and Adeimantus[br]are working with an 0:15:31.049,0:15:34.088 under-theorized notion[br]of justice. 0:15:34.088,0:15:38.043 The picture that they have is[br]that justice is roughly acting 0:15:38.043,0:15:41.083 in conformity with the[br]regulations that society 0:15:41.083,0:15:45.022 imposes upon us as[br]considered to be 0:15:45.022,0:15:47.007 meritorious, loosely speaking. 0:15:47.007,0:15:50.097 Being just is roughly[br]doing what the laws 0:15:50.097,0:15:52.532 say you should do. 0:15:52.532,0:15:56.049 Socrates, by contrast, goes on[br]and gives us a much more 0:15:56.049,0:15:59.042 sophisticated account[br]of justice. 0:15:59.042,0:16:03.033 But if those two[br]characterizations are what 0:16:03.033,0:16:07.084 philosophers sometimes like to[br]call extensionally equivalent, 0:16:07.084,0:16:10.087 then Socrates isn't cheating. 0:16:10.087,0:16:13.944 What it is to be extensionally[br]equivalent, is that you pick 0:16:13.944,0:16:17.065 out the same set of actions[br]in the world. 0:16:17.065,0:16:21.039 So Socrates' claim is that[br]it's a law that you're 0:16:21.039,0:16:24.635 supposed to be honest and[br]not murder people. 0:16:24.635,0:16:27.049 But it's also the case that[br]somebody with a soul 0:16:27.049,0:16:31.009 structured in the way that he[br]has called "just" will not 0:16:31.009,0:16:34.039 steal, and not murder people. 0:16:34.039,0:16:39.084 It's a norm of justice that one[br]will have piety towards 0:16:39.084,0:16:40.845 one's parents. 0:16:40.845,0:16:43.952 A norm of justice in the[br]conventional sense. 0:16:43.952,0:16:47.365 So, too, says Socrates, is it a[br]norm of justice in the sense 0:16:47.365,0:16:49.061 that he's characterized[br]that you will have 0:16:49.061,0:16:51.059 piety for one's parents. 0:16:51.059,0:16:53.051 And so on. 0:16:53.051,0:16:58.072 So the picture is that the[br]notion, the more filled-out 0:16:58.072,0:17:02.039 notion of justice that Socrates[br]has provided us with, 0:17:02.039,0:17:05.094 accords well enough with the[br]notion of justice that Glaucon 0:17:05.094,0:17:10.058 and Adeimantus were interested[br]in to make this not cheating. 0:17:10.058,0:17:15.052 And that allows Socrates to make[br]two kinds of arguments in 0:17:15.052,0:17:19.029 favor of the intrinsic[br]values of justice. 0:17:19.029,0:17:24.003 The first comes at the end of[br]book four, where he argues 0:17:24.003,0:17:28.023 that justice is a[br]kind of health. 0:17:28.023,0:17:33.055 Roughly, justice is to the soul[br]as health is to the body. 0:17:33.055,0:17:37.007 A healthy body is one whose[br]parts are doing what their 0:17:37.007,0:17:39.032 parts are supposed to do. 0:17:39.032,0:17:42.081 Your body is healthy if your[br]heart is pumping blood at the 0:17:42.081,0:17:46.042 right sort of pace, so that[br]your brain is getting the 0:17:46.042,0:17:48.095 amount of oxygen that it needs,[br]and your fingertips are 0:17:48.095,0:17:53.077 getting the amount of blood[br]that they need, and so on. 0:17:53.077,0:17:59.061 So just as health is of both[br]intrinsic and instrumental 0:17:59.061,0:18:06.175 value to us in the body, so, too[br]is justice, which is the 0:18:06.175,0:18:11.012 health of the soul, of both[br]intrinsic and instrumental 0:18:11.012,0:18:17.075 value to us as spiritual in[br]addition to physical beings. 0:18:17.075,0:18:22.051 We're spiritual here in[br]a very modest sense. 0:18:22.051,0:18:23.079 So that's the first argument. 0:18:23.079,0:18:29.023 The first argument is an idea[br]that presupposes that there's 0:18:29.023,0:18:32.008 a way that it's good[br]for people to work. 0:18:32.008,0:18:34.074 And we'll revisit this[br]in the context of our 0:18:34.074,0:18:36.064 discussion of Aristotle. 0:18:36.064,0:18:39.015 So there's a way that your body[br]is supposed to work: The 0:18:39.015,0:18:41.006 heart is supposed to do this,[br]the lungs are supposed to do 0:18:41.006,0:18:43.000 this, you knees are supposed[br]to do this, your ears are 0:18:43.000,0:18:44.185 supposed to do that,[br]and so on. 0:18:44.185,0:18:47.001 And we have a picture of[br]what health amounts to. 0:18:47.001,0:18:51.024 So, too, says Plato, the[br]excavation project that he's 0:18:51.024,0:18:55.093 engaged in thinking about the[br]city-state analogy brings out 0:18:55.093,0:18:59.545 what it would be for a soul to[br]be healthy, and it turns out 0:18:59.545,0:19:05.007 that health for the soul is to[br]be arranged in the way that 0:19:05.007,0:19:06.095 justice mandates. 0:19:06.095,0:19:09.023 So that's the first argument[br]that he offers. 0:19:09.023,0:19:12.791 It's an argument through[br]something that Glaucon and 0:19:12.791,0:19:16.009 Adeimantus have conceded to[br]have intrinsic as well as 0:19:16.009,0:19:21.004 instrumental utility, and a[br]claim that once you understand 0:19:21.004,0:19:25.063 what justice is, you can see the[br]direct analogy between the 0:19:25.063,0:19:29.021 soul and justice and the[br]body and health. 0:19:29.021,0:19:33.082 The second pair of arguments[br]occurs in book nine, and 0:19:33.082,0:19:37.915 concern the question[br]of happiness. 0:19:37.915,0:19:41.079 The first argument there is an[br]argument that we'll actually 0:19:41.079,0:19:44.084 hear again when we read John[br]Stuart Mill at the beginning 0:19:44.084,0:19:47.778 of our utilitarianism section. 0:19:47.778,0:19:51.013 And that's an argument which[br]runs as follows. 0:19:51.013,0:19:54.032 The person who has developed[br]the capacity for 0:19:54.032,0:19:59.075 self-regulation, the self-ruler,[br]has along the way, 0:19:59.075,0:20:06.055 because of the kinds of beings[br]we are, also experienced all 0:20:06.055,0:20:10.004 of the other kinds[br]of pleasure. 0:20:10.004,0:20:13.018 In some ways, this is like[br]the Freudian story. 0:20:13.018,0:20:16.047 We start off as a bundle of[br]desires, and we take the 0:20:16.047,0:20:19.022 things that we want, without[br]consideration of their 0:20:19.022,0:20:21.058 long-term consequences for us. 0:20:21.058,0:20:27.008 And over time, we come and get[br]that unregulated bundle of 0:20:27.008,0:20:30.235 needs into a certain[br]kind of order. 0:20:30.235,0:20:34.082 We regulate it first by means[br]of praise and blame, roughly 0:20:34.082,0:20:38.023 making use of the honor part[br]of ourselves, and then we 0:20:38.023,0:20:40.052 regulate it by means[br]of reflection and 0:20:40.052,0:20:42.029 self-understanding. 0:20:42.029,0:20:46.043 So the person who has gotten[br]their soul into a harmonious 0:20:46.043,0:20:51.881 state is in a subjectively[br]excellent position, because he 0:20:51.881,0:20:56.009 or she has experienced all of[br]the pleasures that the person 0:20:56.009,0:21:02.028 who doesn't do self-regulation[br]has experienced, and in 0:21:02.028,0:21:05.086 addition, has experienced the[br]kinds of pleasures that are 0:21:05.086,0:21:09.072 available to us only if our[br]soul is well-ordered. 0:21:09.072,0:21:14.032 So all of us have experienced[br]the pleasure of checking 0:21:14.032,0:21:19.001 Facebook and playing Tetris. 0:21:19.001,0:21:23.034 But only some of us have[br]experienced the pleasure of 0:21:23.034,0:21:27.001 turning off our Internet during[br]class, and leaving it 0:21:27.001,0:21:30.009 off and listening to[br]what it is that's 0:21:30.009,0:21:32.093 being said by our professor. 0:21:32.093,0:21:36.004 And those of us who have had[br]the great pleasure of doing 0:21:36.004,0:21:43.082 the second, says Plato, have[br]recognized that that pleasure 0:21:43.082,0:21:47.019 is a greater form of[br]pleasure than the 0:21:47.019,0:21:50.036 pleasure of Angry Birds. 0:21:50.036,0:21:53.004 I'll leave it to those of you[br]who have experienced both to 0:21:53.004,0:21:55.276 assess that argument. 0:21:55.276,0:21:57.065 That's the first argument that[br]he makes in book nine. 0:21:57.065,0:22:00.005 The second argument is actually[br]a very interesting 0:22:00.005,0:22:03.087 argument, and one for which[br]full understanding would 0:22:03.087,0:22:06.088 require my going through the[br]allegory of the cave, which 0:22:06.088,0:22:08.056 I'm not going to do right now. 0:22:08.056,0:22:13.035 But suffice to say that it is[br]part of the Republic, and part 0:22:13.035,0:22:17.019 of Plato's philosophy in[br]general, to say that the kinds 0:22:17.019,0:22:20.092 of earthly pleasures that we[br]experience in interacting with 0:22:20.092,0:22:23.336 objects are, in fact, a certain 0:22:23.336,0:22:25.054 kind of unreal pleasure. 0:22:25.054,0:22:30.027 They aren't interacting with[br]that which is most real. 0:22:30.027,0:22:34.062 What is most real, says Plato,[br]are not the approximations of 0:22:34.062,0:22:38.034 circles that we encounter when[br]we use the PowerPoint Draw 0:22:38.034,0:22:41.017 program to make the snowman[br]in the slide. 0:22:41.017,0:22:46.026 They are the mathematical[br]ideals of circles. 0:22:46.026,0:22:54.001 The true nature of wisdom, for[br]example, is not the wisdom 0:22:54.001,0:22:56.059 that we encounter in the[br]individuals around us, so 0:22:56.059,0:23:01.003 that's wonderful, but rather the[br]form of wisdom, of which 0:23:01.003,0:23:05.037 all of these instances[br]are simply imitation. 0:23:05.037,0:23:09.066 So, too, with every other[br]pleasure that we have. So 0:23:09.066,0:23:14.016 there's the earthly pleasures,[br]and then there's a domain of 0:23:14.016,0:23:17.065 things with which we[br]interact which lies 0:23:17.065,0:23:21.009 beyond the earthly realm. 0:23:21.009,0:23:25.005 I spend a lot of times watching[br]children's movies, 0:23:25.005,0:23:26.098 being the parent[br]of two of them. 0:23:26.098,0:23:30.064 And among the movies that I've[br]seen recently with my younger 0:23:30.064,0:23:33.012 child is Narnia. 0:23:33.012,0:23:35.051 And among the movies that I've[br]seen recently with my older 0:23:35.051,0:23:37.065 child is Infection. 0:23:37.065,0:23:41.057 And we've also watched The[br]Matrix, and we've also watched 0:23:41.057,0:23:43.027 The Truman Show. 0:23:43.027,0:23:49.074 All of these are movies that[br]make Plato's point. 0:23:49.074,0:23:55.003 The gambit in each of these[br]films is that the reality 0:23:55.003,0:24:00.086 which you take to be genuine[br]and most profound-- 0:24:00.086,0:24:04.077 this earthly realm, in the case[br]of Narnia, the experience 0:24:04.077,0:24:07.093 that you're having right now, in[br]the case of The Matrix, and 0:24:07.093,0:24:13.083 so on, is, in fact, but a shadow[br]of that which truly 0:24:13.083,0:24:16.794 lies beyond. 0:24:16.794,0:24:22.066 And this theme is, in fact, a[br]central theme of almost every 0:24:22.066,0:24:25.004 religious tradition. 0:24:25.004,0:24:28.053 That the domain of the secular,[br]the domain of the 0:24:28.053,0:24:32.555 mundane, the domain of the[br]worldly, is in some sense 0:24:32.555,0:24:36.014 unreal, and there is, in[br]addition, a domain of the 0:24:36.014,0:24:41.016 beyond, interaction with which[br]provides a kind of good that 0:24:41.016,0:24:46.071 is so immeasurably better than[br]the good of interacting with 0:24:46.071,0:24:50.059 the world, that there's almost[br]no comparison between them. 0:24:50.059,0:24:56.009 And Plato's Socrates, when he[br]says, the person with the 0:24:56.009,0:25:01.069 well-regulated soul spends his[br]or her time contemplating the 0:25:01.069,0:25:06.000 form is making exactly the same[br]kind of claim that, for 0:25:06.000,0:25:11.002 example, a religious Christian[br]would make in saying that in 0:25:11.002,0:25:16.005 giving up the earthly good and[br]focusing instead on what is 0:25:16.005,0:25:22.023 spiritually valuable, one gains[br]a kind of possibility 0:25:22.023,0:25:26.057 for flourishing that is[br]incomparable to that which you 0:25:26.057,0:25:29.012 can get in the earthly domain. 0:25:29.012,0:25:34.094 So the second argument around[br]happiness claims not merely 0:25:34.094,0:25:37.009 that the person with the[br]well-regulated soul has 0:25:37.009,0:25:42.043 experienced all the pleasures[br]and felt subjectively that 0:25:42.043,0:25:46.071 this one is the best,[br]but, in fact, that 0:25:46.071,0:25:49.075 that person is correct. 0:25:49.075,0:25:53.059 That the greatest form of[br]pleasures comes from the 0:25:53.059,0:25:58.091 well-regulated soul that spends[br]its time interacting 0:25:58.091,0:26:04.052 not with the mundane and[br]earthly, but with the ideas of 0:26:04.052,0:26:06.009 the beyond. 0:26:06.009,0:26:08.093 Now, final quote. 0:26:08.093,0:26:11.063 0:26:11.063,0:26:15.055 One of the ways of bringing home[br]the point that Socrates 0:26:15.055,0:26:20.014 has made is by means[br]of vivid imagery. 0:26:20.014,0:26:23.001 We'll find throughout, in[br]every single one of the 0:26:23.001,0:26:26.064 authors that we read, that[br]they are trying to make 0:26:26.064,0:26:30.032 arguments that appeal to the[br]various parts of your soul. 0:26:30.032,0:26:33.018 I just gave you a bunch of[br]arguments that ran through 0:26:33.018,0:26:38.835 reason, and now we're going to[br]get an image that's supposed 0:26:38.835,0:26:44.075 to stick in your mind, the idea[br]for which Plato has just 0:26:44.075,0:26:46.882 provided argumentation. 0:26:46.882,0:26:48.037 Here's how the passage goes. 0:26:48.037,0:26:49.964 You read it for your[br]reading today. 0:26:49.964,0:26:54.048 "Can it profit anyone to acquire[br]gold unjustly if by 0:26:54.048,0:26:59.938 doing so, he enslaves the best[br]part of himself to the most 0:26:59.938,0:27:01.036 vicious?" Right? 0:27:01.036,0:27:04.008 So the top part of the[br]snowman to the 0:27:04.008,0:27:05.213 bottom part of the snowman. 0:27:05.213,0:27:07.027 And here's the analogy. 0:27:07.027,0:27:10.032 "If he got the gold by enslaving[br]his son or daughter 0:27:10.032,0:27:13.006 to savage or evil men, it[br]wouldn't profit him, no matter 0:27:13.006,0:27:15.754 how much gold he got." Right? 0:27:15.754,0:27:18.846 If I tell you, you can have all[br]the money in the world, 0:27:18.846,0:27:22.019 all you have to do is sell your[br]brother or sister into 0:27:22.019,0:27:25.087 slavery, I assume that that[br]trade-off wouldn't be 0:27:25.087,0:27:29.057 appealing to most of you, and[br]those of you to whom it would 0:27:29.057,0:27:33.685 be, there are actually courses[br]on peer relations over in the 0:27:33.685,0:27:35.002 psychology department. 0:27:35.002,0:27:37.948 "It wouldn't profit him, no[br]matter how much gold he got. 0:27:37.948,0:27:42.002 How, then, could he fail to be[br]wretched if he pitilessly 0:27:42.002,0:27:45.046 enslaves the most divine part[br]of himself to the most 0:27:45.046,0:27:47.003 polluted one?" 0:27:47.003,0:27:48.083 So the idea is this. 0:27:48.083,0:27:55.575 When you steal, when you murder,[br]when you act in ways 0:27:55.575,0:27:59.125 that let the lower part of your[br]soul do what the higher 0:27:59.125,0:28:04.028 part of your soul tells you[br]shouldn't, you're exactly like 0:28:04.028,0:28:09.036 the person who has these[br]ill-gotten gains. 0:28:09.036,0:28:14.001 Just as it's not a good way to[br]make money to sell your son or 0:28:14.001,0:28:18.045 daughter into slavery, so, too,[br]Socrates suggests, it's 0:28:18.045,0:28:23.047 not a good way to make money[br]to sell the higher part of 0:28:23.047,0:28:26.018 your soul into slavery. 0:28:26.018,0:28:32.041 To enslave it to your passions[br]and to your appetites. 0:28:32.041,0:28:38.035 Now, this idea that we can take[br]some of the common wisdom 0:28:38.035,0:28:43.071 about the nature of happiness,[br]but recognize that it captures 0:28:43.071,0:28:49.205 only part of the truth, is one[br]of the things, one of the many 0:28:49.205,0:28:54.011 things, that's going on in the[br]passages from Jonathan Haidt 0:28:54.011,0:28:57.003 that I had you read for today. 0:28:57.003,0:29:00.041 So we read two chapters[br]for today. 0:29:00.041,0:29:03.086 One was required, chapter[br]five, which was about 0:29:03.086,0:29:05.606 contemporary theories[br]of happiness. 0:29:05.606,0:29:08.069 The second, which I recommend[br]to you was the 0:29:08.069,0:29:09.082 chapter about virtues. 0:29:09.082,0:29:12.005 I want to talk about the first[br]of those chapters, the 0:29:12.005,0:29:14.024 happiness chapter. 0:29:14.024,0:29:17.075 So we just heard that Plato[br]points out, or argues, or 0:29:17.075,0:29:22.032 contends, through this long[br]book, that human flourishing 0:29:22.032,0:29:26.049 comes not from material wealth[br]and physical goods, but rather 0:29:26.049,0:29:29.021 from something that it might[br]not occur to you was the 0:29:29.021,0:29:33.002 source of flourishing:[br]reflection and wisdom. 0:29:33.002,0:29:36.022 And the arguments that he makes[br]there make use of the 0:29:36.022,0:29:39.097 resources of the tradition[br]of which he's a part. 0:29:39.097,0:29:42.087 They're set in an ancient Greek[br]context, and they use 0:29:42.087,0:29:46.051 the argumentative tools[br]of philosophy. 0:29:46.051,0:29:52.075 In a similar way, the discussion[br]that Jonathan Haidt 0:29:52.075,0:29:58.009 provides in chapter five tries[br]to do this that is similar to 0:29:58.009,0:30:03.041 Plato, colon: It tries to show[br]that there's some truth in 0:30:03.041,0:30:06.044 common pictures of what[br]happiness amounts to, but that 0:30:06.044,0:30:09.004 they haven't gotten the[br]whole story right. 0:30:09.004,0:30:13.000 And it does so in part by using[br]the strategy which I 0:30:13.000,0:30:14.695 described to you earlier. 0:30:14.695,0:30:17.072 It takes what the common[br]picture looks like, it 0:30:17.072,0:30:21.013 provides a more profound[br]analysis of it, and it shows 0:30:21.013,0:30:24.674 that those pick out roughly[br]the same class of things. 0:30:24.674,0:30:30.049 And Haidt, in particular, in[br]that chapter, presents us with 0:30:30.049,0:30:35.002 two claims. The first[br]is one that he calls 0:30:35.002,0:30:37.078 the progress principle. 0:30:37.078,0:30:42.091 The discovery--for which there[br]seems to be pretty good both 0:30:42.091,0:30:47.000 behavioral and neuroscientific[br]evidence, both within the 0:30:47.000,0:30:50.645 domain of American culture and[br]cross-culturally--that most of 0:30:50.645,0:30:55.011 our pleasure comes not from[br]the achievement of a goal, 0:30:55.011,0:30:58.009 though there is some pleasure[br]that comes from that, but from 0:30:58.009,0:31:04.025 the process of achieving[br]that goal. 0:31:04.025,0:31:07.069 And the second--which hearkens[br]back to the material that we 0:31:07.069,0:31:11.086 read last week from Daniel[br]Kahneman, and the day before 0:31:11.086,0:31:16.073 that from Jonathan Evans--that[br]because we are more sensitive 0:31:16.073,0:31:23.082 to changes in good than to[br]absolute levels of good, more 0:31:23.082,0:31:28.088 of something doesn't always[br]make us happier. 0:31:28.088,0:31:36.006 More of something tends to make[br]us used to that something 0:31:36.006,0:31:41.023 and desirous of the change which[br]comes with having even 0:31:41.023,0:31:42.099 more of that. 0:31:42.099,0:31:46.093 The next slide is going to ask[br]you to have your clickers, so 0:31:46.093,0:31:47.099 if you can take them out,[br]we'll turn to them. 0:31:47.099,0:31:49.492 It's not an interesting[br]slide, I just ask you 0:31:49.492,0:31:51.006 to have your clickers. 0:31:51.006,0:31:53.026 So this gives rise to something[br]which is sometimes 0:31:53.026,0:31:54.097 called the hedonic treadmill. 0:31:54.097,0:32:00.003 The hedonic treadmill is the[br]idea that in order to maintain 0:32:00.003,0:32:04.145 the same amount of happiness,[br]if it's based on material 0:32:04.145,0:32:10.072 goods, requires us to run to[br]stay in the same place. 0:32:10.072,0:32:14.042 And the psychological principles[br]which underlie the 0:32:14.042,0:32:20.012 adaptation principle are exactly[br]the principles that 0:32:20.012,0:32:25.003 governed the cases that Kahneman[br]was describing. 0:32:25.003,0:32:29.009 That we are, as he showed in the[br]visual system, enormously 0:32:29.009,0:32:32.031 sensitive to contrast,[br]and extremely 0:32:32.031,0:32:35.062 bad at absolute judgment. 0:32:35.062,0:32:39.027 And we'll come back to that[br]principle when we read the 0:32:39.027,0:32:43.044 Cass Sunstein paper in the[br]section in ethics. 0:32:43.044,0:32:44.016 OK. 0:32:44.016,0:32:47.036 So my question, polling is open,[br]is "Are you ready to 0:32:47.036,0:32:50.088 move on?" Press one if: "Yes,[br]I can't wait for Aristotle." 0:32:50.088,0:32:53.042 Press two if: "No, you have[br]a question about Plato or 0:32:53.042,0:32:54.093 Haidt." 0:32:54.093,0:32:55.061 OK. 0:32:55.061,0:32:57.033 So this is just to like[br]re-engage you in case you 0:32:57.033,0:32:59.068 zoned out, because I've been[br]jabbering, and the clickers 0:32:59.068,0:33:00.895 are supposed to keep[br]you talking. 0:33:00.895,0:33:01.019 OK. 0:33:01.019,0:33:02.098 We have-- 0:33:02.098,0:33:03.095 oh, shoot. 0:33:03.095,0:33:05.939 This clock was supposed to[br]start automatically; we 0:33:05.939,0:33:07.036 already have 118 of you. 0:33:07.036,0:33:07.098 OK. 0:33:07.098,0:33:09.003 So if you are somebody-- 0:33:09.003,0:33:12.059 can we jump this, or not? 0:33:12.059,0:33:12.091 Oh! 0:33:12.091,0:33:14.023 That was worse. 0:33:14.023,0:33:14.078 OK. 0:33:14.078,0:33:15.009 I'm not going to touch this. 0:33:15.009,0:33:18.051 So if you are somebody who was[br]in category two, and you have 0:33:18.051,0:33:20.571 a question about Plato or Haidt[br]that you would like to 0:33:20.571,0:33:23.047 ask now, please do it before[br]we discover how 0:33:23.047,0:33:25.081 rare a being you are. 0:33:25.081,0:33:28.092 Or perhaps how common. 0:33:28.092,0:33:30.017 All right. 0:33:30.017,0:33:32.002 0:33:32.002,0:33:33.005 No questions? 0:33:33.005,0:33:34.453 Question. 0:33:34.453,0:33:37.077 STUDENT: [INAUDIBLE] 0:33:37.077,0:33:39.845 PROFESSOR: You don't really[br]understand extensional 0:33:39.845,0:33:40.017 equivalents. 0:33:40.017,0:33:40.076 Yes. 0:33:40.076,0:33:41.614 OK. 0:33:41.614,0:33:43.052 So that is a philosopher's[br]term. 0:33:43.052,0:33:45.036 Let's see how rare you[br]are, and then I'll-- 0:33:45.036,0:33:46.562 ah, OK. 0:33:46.562,0:33:49.079 So though you are in the 9%, I[br]will nonetheless answer your 0:33:49.079,0:33:51.025 question for you. 0:33:51.025,0:33:57.832 So two characterizations are[br]extensionally equivalent if 0:33:57.832,0:34:01.009 they pick out the same set[br]of things in the world. 0:34:01.009,0:34:06.073 So if I say: I'm interested in[br]picking out all geometrical 0:34:06.073,0:34:12.037 figures that have four corners[br]that are equally spaced from 0:34:12.037,0:34:16.052 one another, and you say, I'm[br]interested in picking out all 0:34:16.052,0:34:21.006 geometrical figures that have[br]four sides that are of equal 0:34:21.006,0:34:25.465 length and at right angles to[br]one another, you're picking 0:34:25.465,0:34:29.082 out squares and I'm picking out[br]squares, even though we 0:34:29.082,0:34:33.008 gave different descriptions[br]of what we're picking out. 0:34:33.008,0:34:37.022 If I'm picking out all female[br]siblings, and you're picking 0:34:37.022,0:34:42.009 out all sisters, we're picking[br]out the same class of things, 0:34:42.009,0:34:45.057 even though we're using[br]different descriptions. 0:34:45.057,0:34:46.003 OK. 0:34:46.003,0:34:49.396 So it's a democracy. 0:34:49.396,0:34:52.014 Plato doesn't think that's the[br]best form of government, but 0:34:52.014,0:34:52.755 here we are. 0:34:52.755,0:34:54.098 We're going to move on. 0:34:54.098,0:34:55.097 All right. 0:34:55.097,0:34:57.056 Aristotle. 0:34:57.056,0:34:59.034 So at the very least, right,[br]you're taking a philosophy 0:34:59.034,0:35:02.085 class, you deserve to have this[br]picture explained to you. 0:35:02.085,0:35:06.111 Since you see it on every poster[br]on campus. "Come to the 0:35:06.111,0:35:08.026 writing center!" I don't know[br]why they put Plato and 0:35:08.026,0:35:10.845 Aristotle on the "Come to the[br]writing center," but I might 0:35:10.845,0:35:13.384 as well tell you what's going[br]on in this picture. 0:35:13.384,0:35:17.045 So this picture is a famous[br]painting by the great 0:35:17.045,0:35:18.078 Renaissance painter, Raphael. 0:35:18.078,0:35:20.575 It's called The School[br]of Athens. 0:35:20.575,0:35:23.037 Many of the figures within[br]the larger painting 0:35:23.037,0:35:24.093 represent his friends. 0:35:24.093,0:35:28.096 You can go and see this in the[br]Vatican, if you're interested. 0:35:28.096,0:35:32.097 In the center of that painting,[br]famously, are Plato, 0:35:32.097,0:35:35.058 standing right here,[br]and Aristotle, 0:35:35.058,0:35:36.093 standing right here. 0:35:36.093,0:35:40.081 Plato is holding in his hand,[br]you can almost read it, a book 0:35:40.081,0:35:45.007 called the Timaeus, which is a[br]book of cosmology, and he's 0:35:45.007,0:35:49.005 pointing upward, many say[br]because he's pointing to the 0:35:49.005,0:35:53.005 realm of the forms. 0:35:53.005,0:35:56.000 Aristotle, by contrast, is[br]holding in his hand the 0:35:56.000,0:35:57.094 Ethics, the book that we're[br]reading, right? 0:35:57.094,0:36:00.003 The Nicomachean Ethics,[br]there it is. 0:36:00.003,0:36:03.416 You have a book that's on[br]the wall of the Vatican. 0:36:03.416,0:36:04.002 That's so exciting. 0:36:04.002,0:36:07.477 You have a $6 paperback[br]copy, but still. 0:36:07.477,0:36:09.473 You have, in some[br]ways, the book. 0:36:09.473,0:36:13.089 And Aristotle's hand is here[br]for one of two reasons. 0:36:13.089,0:36:16.078 Either because he's pointing to[br]the earthly domain as part 0:36:16.078,0:36:21.202 of his denial of the Platonic[br]picture of forms, or because 0:36:21.202,0:36:24.094 he's talking about the doctrine[br]of the mean, about 0:36:24.094,0:36:27.043 which all of you know a great[br]deal, because it's what we 0:36:27.043,0:36:29.009 read for today. 0:36:29.009,0:36:29.049 OK. 0:36:29.049,0:36:33.087 So next time you see this[br]picture, at least you'll know 0:36:33.087,0:36:37.052 who these two characters are:[br]Plato and Aristotle. 0:36:37.052,0:36:41.034 Aristotle, as you know, was[br]a student of Plato's. 0:36:41.034,0:36:45.046 And the text that we read for[br]today is, to my mind, one of 0:36:45.046,0:36:49.026 the most profound works of[br]psychology written in the last 0:36:49.026,0:36:51.006 2500 years. 0:36:51.006,0:36:54.076 It is, however, miserably[br]difficult to read, in part 0:36:54.076,0:36:58.001 because, though Aristotle wrote[br]dialogues, most of those 0:36:58.001,0:37:01.001 dialogues were lost. And what[br]we have here are basically 0:37:01.001,0:37:02.059 Aristotle's lecture notes. 0:37:02.059,0:37:05.053 You notice that on one of the[br]pages he says, "and now we'll 0:37:05.053,0:37:07.473 go and look at the[br]chart." Right? 0:37:07.473,0:37:09.038 He had--like--some papyrus[br]version of 0:37:09.038,0:37:10.675 these PowerPoint slides. 0:37:10.675,0:37:12.906 I don't know if they were[br]animated with--like--people 0:37:12.906,0:37:14.154 who walked back and forth. 0:37:14.154,0:37:18.064 But what we have here are[br]notes of a kind that are 0:37:18.064,0:37:20.037 rather difficult to read. 0:37:20.037,0:37:24.017 So because this is, in many[br]ways, my favorite book in the 0:37:24.017,0:37:27.083 whole world, much of what's[br]going to go on in the next 0:37:27.083,0:37:30.165 slide is that I'm just going to[br]give you some quotes from 0:37:30.165,0:37:34.041 it, and tell you what's[br]going on in the text. 0:37:34.041,0:37:36.306 So this is Aristotle's Ethics. 0:37:36.306,0:37:38.379 If Plato is thirty seconds,[br]this is going to 0:37:38.379,0:37:39.762 take sixty or so. 0:37:39.762,0:37:43.054 Let me tell you what's[br]going on. 0:37:43.054,0:37:46.025 So the discussion that we read[br]starts at the beginning of 0:37:46.025,0:37:49.057 book one, with an argument[br]that's sometimes called, the 0:37:49.057,0:37:53.096 argument in favor of the summum[br]bonum --you don't have 0:37:53.096,0:37:56.004 to write it down, which is why[br]I didn't put it on the 0:37:56.004,0:37:59.066 slide--sometimes called[br]the highest good. 0:37:59.066,0:38:00.075 That which is pursued[br]for its own sake. 0:38:00.075,0:38:03.048 And the argument here is[br]basically what we might call a 0:38:03.048,0:38:05.076 regress argument. 0:38:05.076,0:38:08.025 It's like the intrinsic/[br]instrumental value argument 0:38:08.025,0:38:09.096 that we heard in Plato. 0:38:09.096,0:38:13.885 The idea is that every good,[br]that is, everything that you 0:38:13.885,0:38:17.073 seek, is pursued either for[br]itself, or for the sake of 0:38:17.073,0:38:18.079 something else. 0:38:18.079,0:38:21.457 And if it's pursued for the[br]sake of something else, it 0:38:21.457,0:38:24.073 must bottom out or talk up. 0:38:24.073,0:38:26.091 Summum bonum, the[br]highest good, it 0:38:26.091,0:38:29.069 must top up in something. 0:38:29.069,0:38:33.051 And so the inquiry that we[br]engage in when we do what 0:38:33.051,0:38:36.009 Aristotle calls political[br]science--which is not 0:38:36.009,0:38:39.026 political science like in the[br]Poli Sci department--it's 0:38:39.026,0:38:43.036 political science in the sense[br]of the study of human beings 0:38:43.036,0:38:46.051 as political, that is,[br]social animals. 0:38:46.051,0:38:51.007 So the study of ourselves as[br]socially embedded creatures is 0:38:51.007,0:38:55.009 the study of what is the highest[br]good for the human. 0:38:55.009,0:38:58.097 And the highest good for the[br]human being, says Aristotle, 0:38:58.097,0:39:04.001 is--both in the minds of the[br]common man, that is, both in 0:39:04.001,0:39:07.091 sort of what you would read in[br]the equivalent of the mass 0:39:07.091,0:39:12.053 media in ancient Greece,[br]and in the mind of the 0:39:12.053,0:39:17.073 educated--what was called[br]eudaemonia or flourishing, 0:39:17.073,0:39:19.095 sometimes translated[br]as happiness. 0:39:19.095,0:39:24.017 That's what everybody[br]is going for. 0:39:24.017,0:39:27.031 So that's the beginning of[br]the passages that we 0:39:27.031,0:39:28.136 read from book one. 0:39:28.136,0:39:29.083 There's the question,[br]what's the thing 0:39:29.083,0:39:30.069 that everybody's after? 0:39:30.069,0:39:33.756 And the answer is, everybody's[br]after the same thing. 0:39:33.756,0:39:37.007 They're after happiness,[br]flourishing, eudaimonia. 0:39:37.007,0:39:38.085 So the next question is this. 0:39:38.085,0:39:40.071 What sort of happiness? 0:39:40.071,0:39:45.564 What is it that we mean when we[br]set out to seek happiness? 0:39:45.564,0:39:48.064 And here Aristotle runs through[br]this inventory of 0:39:48.064,0:39:50.059 answers that have[br]been provided. 0:39:50.059,0:39:54.038 And you'll notice, good student[br]that he is of Plato's, 0:39:54.038,0:39:58.046 that this taxonomy here is going[br]to look pretty familiar. 0:39:58.046,0:40:02.013 If it's the pleasures of[br]gratification, that is, the 0:40:02.013,0:40:03.019 pleasures that Plato[br]would call the 0:40:03.019,0:40:04.038 pleasures of appetite? 0:40:04.038,0:40:07.082 "No," says Aristotle, and he[br]gives some reasons for that. 0:40:07.082,0:40:10.043 Is it the pleasures of honor,[br]what Plato would call the 0:40:10.043,0:40:11.072 pleasures of spirit? 0:40:11.072,0:40:15.042 "No," says Aristotle, and he[br]gives some reasons for it. 0:40:15.042,0:40:18.098 Is it, then, the pleasures of[br]reflection, the things which 0:40:18.098,0:40:20.031 come from reason? 0:40:20.031,0:40:22.045 "Yes!" Says Aristotle. 0:40:22.045,0:40:25.034 And now he goes on to give[br]some reasons for it. 0:40:25.034,0:40:28.087 But the reasons that he gives[br]for it look different from the 0:40:28.087,0:40:33.007 reasons that Plato gave. Because[br]Aristotle rejects 0:40:33.007,0:40:38.021 Plato's idea of the forms.[br]Aristotle is not looking to a 0:40:38.021,0:40:40.082 domain beyond to defend[br]his view. 0:40:40.082,0:40:44.007 He's looking to a domain within[br]to defend his view. 0:40:44.007,0:40:45.088 It's 11:17. 0:40:45.088,0:40:47.095 I'm going to do one more slide,[br]and then we'll finish 0:40:47.095,0:40:50.558 up with Aristotle[br]next lecture. 0:40:50.558,0:40:53.082 So the question is, if you can't[br]turn to the form as your 0:40:53.082,0:40:55.009 justification for reason-- 0:40:55.009,0:40:57.013 remember, Plato has this[br]explanation: "Why 0:40:57.013,0:40:58.414 is reason so good? 0:40:58.414,0:41:01.001 It lets you connect to a domain[br]beyond yourselves." 0:41:01.001,0:41:03.012 Aristotle can't give[br]that answer. 0:41:03.012,0:41:05.038 What, then, makes[br]reason so good? 0:41:05.038,0:41:07.535 Well, here's the argument. 0:41:07.535,0:41:10.018 Every object in the world,[br]he says, has a function. 0:41:10.018,0:41:12.009 The function of a knife[br]is to cut well. 0:41:12.009,0:41:15.097 The function of a paperweight[br]is to hold down papers. 0:41:15.097,0:41:19.051 The function of a laser pointer[br]is to direct attention 0:41:19.051,0:41:20.993 towards the slide, and so on. 0:41:20.993,0:41:25.265 And a good one of those things[br]is one which does 0:41:25.265,0:41:29.005 its function well. 0:41:29.005,0:41:32.091 Its function is that which set[br]it apart from other entities. 0:41:32.091,0:41:36.089 So good paperweights are things[br]that are heavy, and bad 0:41:36.089,0:41:40.003 paperweights are things that are[br]light, or round, so that 0:41:40.003,0:41:41.066 they roll off. 0:41:41.066,0:41:44.039 Or invisible, so that[br]you can't find them. 0:41:44.039,0:41:47.205 Or too heavy to move, so that[br]you can't pick them up off 0:41:47.205,0:41:48.042 your paper. 0:41:48.042,0:41:52.049 So when something has a[br]function, a good version of 0:41:52.049,0:41:58.851 that thing has manifest in[br]itself that which allows that 0:41:58.851,0:42:02.063 object to perform its function[br]especially well. 0:42:02.063,0:42:04.091 Well, what's the function[br]of human beings? 0:42:04.091,0:42:07.094 Well, to answer that question,[br]we have to answer the question 0:42:07.094,0:42:10.026 what is special about[br]human beings? 0:42:10.026,0:42:13.022 What distinguishes us from[br]plants, which take in 0:42:13.022,0:42:15.099 nutrition, and from animals,[br]which are capable of 0:42:15.099,0:42:18.049 locomotion and feeling[br]sensation? 0:42:18.049,0:42:22.034 What distinguishes us from[br]those beings is reason. 0:42:22.034,0:42:26.004 So just as knives are great when[br]they cut well, humans are 0:42:26.004,0:42:29.056 great when they do that special[br]human thing especially 0:42:29.056,0:42:31.062 well when they reason well. 0:42:31.062,0:42:36.125 "Reason is," he writes at 1098,[br]"the special function of 0:42:36.125,0:42:39.037 a human being." What, then,[br]is the human good? 0:42:39.037,0:42:43.073 Well, the good for a knife[br]is to be most manifestly 0:42:43.073,0:42:45.007 knife-like, right? 0:42:45.007,0:42:48.034 I mean, all those magic swords[br]that you get in plays and 0:42:48.034,0:42:49.076 movies and books? 0:42:49.076,0:42:51.544 What makes them good swords? 0:42:51.544,0:42:54.033 That they're especially able to[br]slay your enemies, right? 0:42:54.033,0:42:56.068 That's why the swords[br]are good swords. 0:42:56.068,0:43:01.005 So what makes you the Sword of[br]Lancelot of human beings? 0:43:01.005,0:43:05.625 It's that your soul is[br]structured in such a way that 0:43:05.625,0:43:09.011 you do what is best and[br]most completely 0:43:09.011,0:43:11.004 and distinctly human. 0:43:11.004,0:43:14.073 The good human being is the one[br]that does the human stuff 0:43:14.073,0:43:18.073 best of all, and the human[br]stuff turns out to be 0:43:18.073,0:43:23.096 reasoning and acting in[br]accord with virtue. 0:43:23.096,0:43:27.022 So the question that we'll turn[br]to at the beginning of 0:43:27.022,0:43:28.055 next lecture-- 0:43:28.055,0:43:31.011 and you're all in a position[br]to read the punchline, in 0:43:31.011,0:43:33.866 fact, you should have read[br]the punchline for today-- 0:43:33.866,0:43:39.066 is what does the virtue look[br]like that makes us distinctly 0:43:39.066,0:43:43.067 and most excellently human,[br]and how is it cultivated? 0:43:43.067,0:43:48.002 So for Thursday, we[br]are reading three 0:43:48.002,0:43:51.016 really fantastic things. 0:43:51.016,0:43:54.055 We're reading selections from[br]The Iliad, and I've given you 0:43:54.055,0:43:56.095 two choices of ways[br]to do that. 0:43:56.095,0:43:58.006 Pleas look at the[br]reading guide. 0:43:58.006,0:44:01.055 You can either read all of book[br]one or you can look at 0:44:01.055,0:44:04.000 the context of each of the[br]passages that Jonathan Shay 0:44:04.000,0:44:07.005 gives us, and I've given you[br]instructions how to do that. 0:44:07.005,0:44:09.098 We're reading Jonathan Shay's[br]incredible book, Achilles in 0:44:09.098,0:44:13.012 Vietnam, and we're also reading[br]Stanley Milgram's 0:44:13.012,0:44:17.011 famous 1963 "Behavioral Study[br]of Obedience" paper. 0:44:17.011,0:44:20.044 So we'll start with our[br]Aristotle, and then we'll move 0:44:20.044,0:44:24.001 on to our discussions[br]of those three. 0:44:24.001,9:59:59.000
