  1. 0:06Hey Vsauce!
  2. 0:11Michael here.
  3. 0:15And here.
  4. 0:18Michael here!
  5. 0:19hey vsauce!
  6. 0:22what is here?
  7. 0:24…. what is there?
  8. 0:26what is there?
  9. 0:28What REALLY exists?
  10. 0:30Do waves exist or are there just things that are wavy?
  11. 0:35When does a piece of food I’ve eaten stop being food and become me?
  12. 0:41Do chairs exist?
  13. 0:46Ontology is the philosophy of existence.
  14. 0:49And chairs are what philosophers call ORDINARY OBJECTS.
  15. 0:58Ordinary objects are the plain old common sense things we deal with every day: spoons,
  16. 1:04buckets, rocks, stuff like that.
  17. 1:07Their existence is as obvious as possible
  18. 1:11but the more we try to sus out where they are, the more sus they become.
  19. 1:19First of all, sure, this could all be a dream.
  20. 1:24Maybe we’ve all been hallucinating chairs all these years.
  21. 1:27Or this could part of the simulated reality pumped into our brains while our bodies are
  22. 1:33harvested for energy.
  23. 1:36But underneath that skepticism there’s a deeper ONTOLOGICAL question that we need to
  24. 1:41answer first.
  25. 1:43Regardless of whether this spoon is made of real atoms or simulated atoms, is it really
  26. 1:50possible to be “made of” something?
  27. 1:55Take a look at these two things.
  28. 1:57As we all know, two minus one is … TWO?!
  29. 2:02There ARE two things here:
  30. 2:04An origami crane AND a piece of paper.
  31. 2:07I’m kidding, of course, there’s really just one: the crane and the piece of paper
  32. 2:13are the same.
  33. 2:15But watch this.
  34. 2:25Where’d the crane go?
  35. 2:32If the paper and the crane were truly identical, they would share everything in common.
  36. 2:37But clearly they don’t: the paper can survive being unfolded, the crane cannot.
  37. 2:43Also, I made the crane, but I didn’t make the paper.
  38. 2:47And the paper was around before the crane.
  39. 2:50For two things that are the same, they sure are different.
  40. 2:55This relationship is called CONSTITUTION: paper constitutes the crane.
  41. 3:00It’s a one-to-one relationship, but there’s another kind of “being made of” going
  42. 3:06on here, too.
  43. 3:08This paper is made not of ONE other thing, but of sextillions of things: fundamental
  44. 3:14subatomic particles: electrons and quarks, or strings, or physical and virtual fields.
  45. 3:21This many-to-one relationship is called COMPOSITION.
  46. 3:26Philosophers call whatever it is that matter is ultimately composed of SIMPLES: a simple
  47. 3:31is a thing that, unlike a piece of paper, has no parts.
  48. 3:36No substructure.
  49. 3:37Not even a top or bottom.
  50. 3:38It could be the case that there are no simples, that there’s just a never-ending chain of
  51. 3:42smaller and smaller substructure.
  52. 3:45Philosophers call such a reality a GUNKY universe.
  53. 3:50If structure never ends in the other direction and everything turns out to be part of something
  54. 3:53bigger with no final complete composite, that’s what’s known as a JUNKY universe.
  55. 4:00Point is: believing ordinary objects exist and are made up of smaller things is quite
  56. 4:07common.
  57. 4:08It’s called ontological reductionism.
  58. 4:09It’s the position that wholes are NOTHING MORE than their parts.
  59. 4:14But our cranes and our paper challenge that notion. it seems like being MADE OF some things IS different than
  60. 4:22just BEING those things.
  61. 4:24Let’’s agree on what it means to exist.
  62. 4:28Let’s say that for something to exist is simply for there to be more than zero of it.
  63. 4:36Pegasus exists if we mean “are there any winged horses in works of fiction and mythology?”
  64. 4:42And pegasus does not exist if we mean, “are there any physical, flesh-and-blood winged
  65. 4:48horses that evolved on Earth through natural selection.”
  66. 4:53okay, so if we can agree on that, then of course chairs exist!
  67. 4:56There’s this one right here.
  68. 4:58I can see it and feel it and taste it.
  69. 5:03yea. It’s dry and .. a little bit salty.
  70. 5:07Dry and salty are what we call PROPERTIES.
  71. 5:12Properties tell us what things are LIKE.
  72. 5:15For example, this slice of cheese is FLOPPY.
  73. 5:19By noticing and sharing properties, we can let each other know what to expect from things.
  74. 5:25And we all more or less agree on what things there are.
  75. 5:29We give names to stuff and if they catch on, we put them in dictionaries with the word
  76. 5:33“noun” next to them.
  77. 5:36But are all of these nouns an inventory of the universe … or an inventory of things
  78. 5:42we MADE?
  79. 5:43Let me put it this way: do islands exist?
  80. 5:47Well, it’s in the dictionary and a quick look around confirms that there are more than
  81. 5:51zero islands, so yes.
  82. 5:54Islands exist.
  83. 5:56But what about incars?
  84. 6:00An incar is a car that is IN a garage.
  85. 6:04As a car leaves a garage, an incar diminishes at the threshold until it collapses into nonexistence.
  86. 6:11Later, an extremely similar incar may emerge at the same threshold when the car returns.
  87. 6:18Are there any cars in garages right now?
  88. 6:21If so, then incars exist.
  89. 6:25You might be thinking, “that’s not a thing.
  90. 6:29you just made that up.
  91. 6:31And it’s silly: “being in a garage” is just a property that a car can have.
  92. 6:37Stop trying to make incars a thing.”
  93. 6:39Ok, first of all, I didn’t make it up, Eli Hirsch did.
  94. 6:43And second of all, if you think incars aren’t things, wait till you hear about islands.
  95. 6:50An incar might just be a relation between a car and a garage but an island is just a
  96. 6:55relation between land and some water.
  97. 6:58Now, “island” might be a more useful concept than “incar,” but does that make islands
  98. 7:04OBJECTIVELY more real than incars?
  99. 7:08And what about trogs?
  100. 7:10A trog is an object whose parts are a tree and whatever dog is nearest.
  101. 7:16Here’s a picture of one.
  102. 7:18Do you see the trog? this is its tree part and this is its dog part.
  103. 7:23You might be thinking, come on, how can THAT be a thing?
  104. 7:26The tree and the dog aren’t even connected!
  105. 7:29well so what?
  106. 7:30These two pieces of fabric aren’t connected and yet they’re a thing called a bikini.
  107. 7:35Now sure, if we cut down this tree and burn it for warmth, we wouldn’t feel the need
  108. 7:40to apologize to what’s left of the trog for destroying its tree part.
  109. 7:46But maybe we should?
  110. 7:48What if some extraterrestrials showed up and said they thought dogs and trees composed
  111. 7:54trogs — would they be wrong?
  112. 7:57Could we convince the otherwise?
  113. 8:01Ontological realists believe that we could.
  114. 8:03That there really is a mind-independent answer to the question, “what is there?”
  115. 8:08People like Theodore Sider believe that the universe has “joints” and we can cut up reality
  116. 8:14up into objective, real things by finding them.
  117. 8:18Ontological anti-realists disagree.
  118. 8:21Their position is that what we think there is is just one way to cut up reality.
  119. 8:25It’s a good one for us and our needs, but it’s not objectively more true than any
  120. 8:30other.
  121. 8:31So who’s right?
  122. 8:32Hmm… well if these blocks compose a tower … what do they compose now?
  123. 8:43Just because we don’t have a name for .. this.. doesn’t necessary mean that I haven’t
  124. 8:47accidentally built something. Does it?
  125. 8:50When DO two or more things compose something else?
  126. 8:56Peter Van Inwagen calls this the special composition question.
  127. 8:59In MATERIAL BEINGS he considers possible answers: maybe things compose something only when they’re
  128. 9:06in contact.
  129. 9:07That’s a good thought, but it doesn’t explain how a BIKINI can be a thing.
  130. 9:11Or why two books are still just two books when one is stacked on top of the other.
  131. 9:17you know,
  132. 9:18Maybe a certain degree of FIXATION is required.
  133. 9:22Or a ‘melding’ … if a surgeon sewed us together and the skin healed with no seam
  134. 9:28and we shared the same blood supply … you know, even then it would seem wrong to say
  135. 9:33that we’d become some new kind of animal.
  136. 9:35There’d still just me and you.
  137. 9:39But like, stuck together.
  138. 9:41The philosophy of parts and wholes is called mereology and
  139. 9:46Mereological Universalism is the belief that there’s an answer to the special composition question
  140. 9:51and the answer is this: any assortment of stuff, no matter how strange or scattered across time and space
  141. 9:59composes a thing.
  142. 10:01some pages compose these books but I don't just have two books here. Oh no, there's also a third thing
  143. 10:06let's call it a "took" because it's parts are Two Books.
  144. 10:10There is also something composed of my left ear, the northern third of every brown trout in
  145. 10:17England, and the Eiffel tower.
  146. 10:19Just because it has no name and no one’s ever talked about it before just shows a lack
  147. 10:23of intrest on our parts.
  148. 10:26To a universalist, eliminating some composites but not others is just too arbitrary.
  149. 10:31We may as well accept them all.
  150. 10:35Eliminativism is any belief that accepts some composites, but eliminates others.
  151. 10:41Peter Van Inwagen, for example, believes that there are no ordinary objects, no chairs or
  152. 10:47shirts or shoes.
  153. 10:50Right here there are just some simples — atoms or whatever — arragned show-wise.
  154. 10:55There isn;t something else here called a shoe.
  155. 10:58But he thinks that because people believe they themselves exist, and he can’t see
  156. 11:02how something could believe it existed without existing in the first place to even think
  157. 11:06that, there must be people.
  158. 11:09He goes further, though, to argue that ALL living thigns exist.
  159. 11:14While admiting he doesn’t have any “knock-down” agruments in their favor, he mentions that
  160. 11:18because simples that are part of a living organism maintain the organism —
  161. 11:23— while shedding some members and gaining others, all while remaining individuated from
  162. 11:28other organisms, unlike, say, waves of water at the moment of collision, clearly, simples
  163. 11:35in the act of a life must compose something.
  164. 11:39That position is ORAGANICISM.
  165. 11:41It’s been called the belief that people exist, but that none of them wear clothes.
  166. 11:48Mereological Nihilism is less generous.
  167. 11:51It’s the belief that there aren’t any trogs or incars OR dogs or trees.
  168. 11:58Because nothing ever composes.
  169. 12:00The nihilist doesn’t believe that there is NOTHING here.
  170. 12:03There are lots of simples, but that’s it.
  171. 12:07That might sound puzzling: how can a bunch of fundamental particles, arranged into atoms
  172. 12:12and molecules that are arranged like this NOT be a chair?
  173. 12:17That’s JUST IS what a chair is!
  174. 12:20Good question.
  175. 12:21Let’s call that deflationism: the belief that this is all silly and that all of these
  176. 12:27positions are talking past each other: they all agree on what reality contains: they all
  177. 12:33believe that there are simples here and that those simples are arranged in a chair shape.
  178. 12:39Since that’s just what a chair IS, they all believe in chairs.
  179. 12:43Those who say they don’t just being weird and contrarian.
  180. 12:49Deflationism has many supporters.
  181. 12:50And it truly is the heart of our issue today.
  182. 12:54But to address it, we should first see why it would be nice if all of these parts did not
  183. 13:01form a chair.
  184. 13:02Let’s begin with over-determination: If chairs really do exist, shouldn’t they be
  185. 13:09able to interact with us?
  186. 13:10The thing is, though, everything this alleged chair can do can be described by referencing the behavior of
  187. 13:16simples here and any other simples that come along.
  188. 13:20An account of the activities of every ATOM in this room, leaves nothing
  189. 13:25for the chair to explain.
  190. 13:28Composites are causally redundant.
  191. 13:32Believing in chairs is like believing that, while yes, the burning gas from my stove completely
  192. 13:38describes why the water in a pot boils, there’s ALSO a magical invisible substance called
  193. 13:44boil-o that comes out of my stove that does the same thing as the flame at the same time
  194. 13:50and if there was no boil-o the flame would warm the water just the same, but there is
  195. 13:54boil-o.
  196. 13:57Chairs are no more real than boil-o.
  197. 13:59Composites over-determine what happens in the world.
  198. 14:04They also lead to over-COUNTING.
  199. 14:07For more on that, let’s say hello to this video’s sponsor.
  200. 14:12Hi.
  201. 14:13I’m Michael Stevens.
  202. 14:14You may know me from such films as ”Lady Gaga - Judas PARODY!
  203. 14:18Key Of Awesome #42” and The Emoji Movie.
  204. 14:22But today, I’m here to talk to you about the Curiosity Box.
  205. 14:25This season, subscribers will be receiving many things, including a shirt celebrating
  206. 14:31the Sherman line, a kit to find out what bacteria is growing on you, a puzzle that celebrates
  207. 14:39the average color of neptune and yes, uranus, and the first ever at-home demonstration of
  208. 14:47impossible colors.
  209. 14:50And right now, if you subscribe with code BOGO, we’ll also send you our entire summer box completely free.
  210. 14:56just pay shipping
  211. 14:58How many THINGS will you be receiving for one ridiculously low price?
  212. 15:02You might think 15: 8 things plus 7 things.
  213. 15:06But don’t forget that you’re ALSO getting this entire collection and THIS entire collection.
  214. 15:12That’s 17 things!
  215. 15:15ORder now.
  216. 15:16That’s a good deal, but the ontology seemed wrong.
  217. 15:21If I count some parts, I shouldn’t also count the whole they compose.
  218. 15:26But if you believe in composite objects you MUST do this, right?
  219. 15:30After all, the composite exists.
  220. 15:32So if this chair contains, say, 100 sextillion atoms, then there are actually AT LEAST 100
  221. 15:41sextillion and one things here: all of these atoms and also a chair.
  222. 15:47That seems wrong.. but wait, there’s more.
  223. 15:52If I take a knife and scrape off a tiny part of this chair … is it still a chair?
  224. 15:59I think most of us would say yes.
  225. 16:01It would still be a chair even if I removed a tiny bit again.
  226. 16:05And again.
  227. 16:06A series of tiny innocuous removals is called a SORITES SEQUENCE.
  228. 16:13The trouble they cause is that while it seems we must accept that each individual step doesn’t
  229. 16:19annihilate the chair, clearly, ENOUGH minute removals WILL eventually leave us with no
  230. 16:24chair.
  231. 16:26Nothing at all, in fact.
  232. 16:27But how can that be?
  233. 16:29How subtracting zero over and over again EVER give a different result?
  234. 16:34Clearly, there must be a point at which a tiny change DOES make a difference.
  235. 16:40Different people might give different answers as to where that line is — but, you know,
  236. 16:46we could just stipulate the boundaries: we could define “chair” in some extreamly
  237. 16:51precise way.
  238. 16:53If we did that, if we defined the shape, function, history, and use that makes something a chair
  239. 16:58so precisely that the even the smallest deviation would make or break its status as a chair
  240. 17:03… how could we know if it’d done it right?
  241. 17:07If we called up God and said, “hey dude, watch this, see this chair?
  242. 17:13Okay, now we’re going to remove a single atom from it.
  243. 17:17Ta da!
  244. 17:18It’s no longer a chair is it?”
  245. 17:21Would God would be like, “pwha!
  246. 17:24Correct! you guys nailed it.
  247. 17:26That is exactly right.
  248. 17:28It was a chair before and now, in my infinite wisdom, I can confirm that that single atom
  249. 17:33was what made the difference.”
  250. 17:38Unless there’s some explanation for why a boundary should be drawn in a precise way
  251. 17:43instead of some other way, our stipulations are just arbitrary.
  252. 17:48Ordinary objects may be unredeemably vague.
  253. 17:53But being vague may actually be a feature of ordinary objects.
  254. 17:58For example, how many people is a crowd?
  255. 18:0110 people standing together in a huge empty park might be more of a group, but 10 people
  256. 18:07standing further apart in a tiny waiting room will feel way more CROWDED.
  257. 18:13The fact that our terms depend on context, that they’re PLASTIC, make it seem less
  258. 18:18and less like they’re describing THINGS and more and more like they’re pragmatic.
  259. 18:23That rather than telling what there is, they tell us to expect.
  260. 18:29Peter Unger has pointed out that there’s at least one kind of thing that CAN survive
  261. 18:34a sorities sequence without paradox: stuff.
  262. 18:38If you innocuously remove pieces from something that is just “some stuff” you will still
  263. 18:45have some stuff after each step until you reach a clear and unambiguous boundary: when
  264. 18:52the last piece is removed, there will no longer be any stuff.
  265. 18:57This might show that there ARE composite objects: stuff.
  266. 19:02As soon as we pretend that some stuff is a THING, though, vagueness sets in.
  267. 19:08Suddenly we’re talking about a thing that can lose parts but also can’t lose parts
  268. 19:13and unless contradictions can exist, words like “chair” don’t really refer to any
  269. 19:19thing in the universe.
  270. 19:21Sorites seqeunces lead to other problems, too.
  271. 19:25Like: the PROBLEM OF THE MANY.
  272. 19:29If removing a tiny number of atoms from this chair still leaves me with a chair, how many chairs are
  273. 19:36here?
  274. 19:37I mean, there’s this one.
  275. 19:39And then there’s this one, which is really similar to the first but doesn't have these atoms on top of
  276. 19:48it.
  277. 19:49I don’t even have to remove atoms for this to be a problem.
  278. 19:51All I have to do try to define which atoms here are part of the chair and which aren’t.
  279. 19:56At the atomic level, there isn’t a definite boundary.
  280. 20:00Near the edge, it will hard to tell whether a particular molecule is part of the moisture
  281. 20:05in the chair or part of the ambient humidity.
  282. 20:09Instead of there being a single chair here, it seems like REALLY there are billions and
  283. 20:14billions of candidates for the chair.
  284. 20:18Which one is the chair?
  285. 20:21But now, suppose that instead of removing pieces like in a sorities sequences or choosing
  286. 20:26pieces like in the problem of the many, we instead discard pieces and replace them with
  287. 20:32new, similar pieces.
  288. 20:34This is the set up to the famous SHIP OF THESEUS paradox.
  289. 20:40Suppose I buy a boat and name it THESEUS.
  290. 20:43Over time, parts of the boat wear out and I replace them with brand new parts.
  291. 20:48After, say 10 years, I might realize that not a single part of my boat was part of the
  292. 20:53boat on the day I bought it.
  293. 20:55Do I now own a different boat?
  294. 20:57Have I owned TWO boats?
  295. 20:59But now suppose the someone has been following me all these years and has been picking up
  296. 21:04each old part I throw out and storing them in a warehouse.
  297. 21:08After I replaced all the original parts they take them and join them back the way
  298. 21:12they way there were 10 years ago.
  299. 21:15Which boat is THESEUS?
  300. 21:17Both?
  301. 21:18If we conclude that ordinary objects don’t exist, the problems of sorites, the many,
  302. 21:26theseus, over-determination, and over-counting all evaporate.
  303. 21:31If there are only simples and they never compose anything, then which one is the ship of theseus
  304. 21:38is easy to answer: neither!
  305. 21:41Neither are the boat and nothing ever was the boat.
  306. 21:44All that happened was that some simples got moved around.
  307. 21:48The simples the scavenger has are the simples I possessed when I bought the boat, but there’s
  308. 21:53no mystery of persistence: removing or exchanging a piece of stuff never left me with the same
  309. 21:59stuff.
  310. 22:00There’s no mystery as to which of the billions of chair candidates here is THE chair and
  311. 22:08the removal of no specific atoms will ever stop it from being a chair because it there
  312. 22:12is no chair here and there never was.
  313. 22:15There are only simples arranged chair-wise.
  314. 22:20The illusion that there ARE composites that can survive changes in parts is an artifact
  315. 22:26of our minds.
  316. 22:27It’s a helpful one that allows us to track certain properties and ignore others, but
  317. 22:33when taken seriously, it obviously isn’t really how the universe works.
  318. 22:38And that’s okay.
  319. 22:39We shouldn’t be embarassed when we talk about boats or chairs.
  320. 22:43Our words for ordinary objects really do refer to actual phenomena and therefore are more
  321. 22:49correct than believing that, say, the sun turned into a black hole yesterday.
  322. 22:55Unlike the false statement that chairs exist, there is NO evidence saying the sun turned
  323. 23:00into a black hole yesterday could even be INCORRECTLY describing.
  324. 23:04Because of this, Trenton Merricks calls the belief in ordinary objects false but, “nearly
  325. 23:10as good as true.”
  326. 23:14This is all silly, though, right?
  327. 23:16Of course there are chairs.
  328. 23:19If you believe that there are some simples arranged chair-wise, then you admit that there’s
  329. 23:24a chair!
  330. 23:25Because that’s just what a chair IS.
  331. 23:27It’s not some additional THING over-and-above these simples: it just IS them.
  332. 23:33Each is still an atom or electron or whatever, but TOGETHER they are a chair.
  333. 23:39Not so fast there, chair-lover.
  334. 23:42What do you MEAN “a chair IS simples arranged chair-wise?”
  335. 23:47the phrase “simples arranged chair-wise” just picks out these simples.
  336. 23:52There’s nothing else for that phrase to refer to.
  337. 23:55There aren’t all of these simples and then ALSO some OTHER simples that are the simples
  338. 24:00arranged chair-wise.
  339. 24:02So do you mean that “chair” is a disguised plural?
  340. 24:06That it refers to lots of things like the phrase “these books”?
  341. 24:11Because “these books” only commits us to the existence of this book and this book
  342. 24:16but not an additional single object that’s called a “these books.”
  343. 24:20Likewise, if “chair” just means this simple and this simple and this simple, then it points
  344. 24:27to a whole bunch of things and not one of them is a chair.
  345. 24:33Sure, “chairs” exist if by chair we mean a word for all these simples.
  346. 24:39But if by chair we mean an actual object in the universe, there just aren’t any, my
  347. 24:46friend.
  348. 24:47Except… maybe there is no chair over-and-above the simples, but instead something happens
  349. 24:53when an assortment of simples are arranged into a chair-shape.
  350. 24:57Each member continues to be a single atom or whatever, but COLLECTIVELY they all simultaneously
  351. 25:04BECOME one thing: a chair.
  352. 25:07Okay, so then either there’s no chair here, just simples; or somehow a miraculous contradiction
  353. 25:14has appeared: many things and ALSO one thing that, despite both clearly differing in that
  354. 25:20respect, are still identical!
  355. 25:24It looks like chairs can’t be identical to the parts they’re supposedly composed
  356. 25:28of..
  357. 25:30but chairs also can’t be DIFFERENT from their composite parts because there’s nothing
  358. 25:34else there and, after counting and accounting for their parts, there’s nothing left for
  359. 25:40the existence of a chair to cause or explain.
  360. 25:45To rescue chairs from non-existence, we need to find a way to show that a chair is independent
  361. 25:52of its atoms — and therefore distinct from them — but not SO distinct that it’s impossibly
  362. 25:59over-and-above them.
  363. 26:00We need to find a way to make chairs ONTOLOGICALLY INNOCENT.
  364. 26:05To have our cake and not have it, too.
  365. 26:08Amie Thomasson does this in a very clever way.
  366. 26:11She points out that if I ask you, “hey, is there anything in the fridge?” and you
  367. 26:16open it, see that’s it empty, and say, “there’s nothing in here” it would be weird if I
  368. 26:21came over, looked inside, found a single eyelash in the corner and said, “ummm EXCUSE me?
  369. 26:29What is this?! you said there was no THING in the fridge, but there was an eyelash and,
  370. 26:35gosh dangit, the whole things is actually FULL!
  371. 26:38Of AIR.”
  372. 26:40That would be weird because when I asked if there was anything in the fridge, it was implied
  373. 26:44that I meant anything TO EAT.
  374. 26:48By arguing that the empty fridge is not REALLY empty, I was using the word “thing” in
  375. 26:53what Thomasson calls a “neutral sense.”
  376. 26:56I used it to mean any and all entities that could possibly be described.
  377. 27:01But you took me to be using “thing” in what she calls a “sortal” sense.
  378. 27:07A sortal is a term that tells us what a thing is in way that allows us to count how many
  379. 27:12there are AND know when there is or isn’t one.
  380. 27:16“Water” is not a sortal.
  381. 27:18If I told you there was water in my basement and you asked, “how many waters?”
  382. 27:22I’d have to use a sortal to answer you.
  383. 27:25For example, “gallons of water.”
  384. 27:27Thomasson argues that the neutral use of “thing” is meaningless when used to ask questions.
  385. 27:33For example, if I used thing in a neutral sense and asked how many orange things are in this video
  386. 27:40you would have no idea how I wanted you to carve it all up
  387. 27:43thus, there would be no would be no single correct answer.
  388. 27:46You might say, "uh, one orange thing? Your shirt?"
  389. 27:50But then I could say, “what, no there's my left sleeve, my right sleeve, the inside of the shirt, the outside of the shirt. Come on, there's way more than one."
  390. 28:00Unless we use a sortal net, any search for what things there are will end in confusion.
  391. 28:06Not because there are no things, but because it hasn’t been made clear what conditions
  392. 28:10to apply when searching.
  393. 28:13For Thomasson, this means that what we find depends on what APPLICATION CONDITIONS we
  394. 28:19use.
  395. 28:20If I ask if there’s anything here that the condition “smaller than a molecule” applies
  396. 28:25to, you could note each such thing and give me an inventory.
  397. 28:30“Chair” would not be on the list.
  398. 28:33But if I asked you if there were any medium-sized rigid-acording-to human strength things here,
  399. 28:39“chair” would probably go on your list, and no single atom would.
  400. 28:44If an application condition is satisfied in the wrold, then the thing is descrbes exists.
  401. 28:51So CHAIRS do exist.
  402. 28:55If the application conditions for one thing are also sufficient for something else, then,
  403. 29:00if we find the first thing, we have found the other because it’s existence is entailed
  404. 29:05ANLYTICALLY by the existence of the first thing — that is, by meaning and logic alone.
  405. 29:12For example, if I say that I live in a house you can conclude — without looking! — that
  406. 29:16I live in a building.
  407. 29:18There’s no paradox here, I don’t live in a house AND a building — two distinct
  408. 29:23things that defy the laws of physics by being co-located.
  409. 29:25Instead, the conditions that apply to a house are also sufficient for building.
  410. 29:32So a single chair is not impossibly identical to some collection of many.
  411. 29:38Nor is it somehow over-and-above its parts.
  412. 29:41Instead, atoms arranged chair-wise merely logically ENTAIL a chair.
  413. 29:47The entailment connects things differentiated by distinct application conditions.
  414. 29:52When we ask which one is the ship of theseus, a puzzle erupts because we’re being too
  415. 29:58neutral.
  416. 29:59We need to say what we mean by “ship of theseus”: if we mean the original parts,
  417. 30:04then this is it.
  418. 30:05Do we mean the thing registered to me by the boat authorities?
  419. 30:08well then it’s this one.
  420. 30:10“But which is the REAL one” is an incomplete pseudoquestion.
  421. 30:14When it come to sorites sequences, I think we need to just stipulate where the boundary
  422. 30:20is.
  423. 30:21I don’t think there’s an objective answer provided by the universe or God as to exactly
  424. 30:26what is and isn’t a chair, but that doesn’t HAVE to mean that there aren’t any chairs,
  425. 30:31it can just mean that every single collection of simples is it’s own unique object independent
  426. 30:38of our minds and that we get to decide which we will call chairs.
  427. 30:43Vagueness comes from our minds and our language but there are no vague objects in the universe.
  428. 30:50We don’t have to believe that our reality is simulated, but I do think we have to believe
  429. 30:57that it’s stipulated: it is a reality that contains not what intelligent machines have
  430. 31:02decided to give us, but what we have decided we have.
  431. 31:07There’s no fact of the matter as to whether calling this a star is the TRUE way to carve
  432. 31:13up this stuff.
  433. 31:14It’s a pretty useful way to do it, and helpful for at least human purposes, but “STAR”
  434. 31:20is a thing WE imposed on the world.
  435. 31:24As Michael Jubien puts it, “there are no things, but as a consequence there are as
  436. 31:29many things as we like.”
  437. 31:32As for the problem of the many, we can simply just admit that there really are billions
  438. 31:37of slightly different chairs here.
  439. 31:40Some include a few boundary atoms that others don’t, but since they all act and react
  440. 31:45pretty much in unison, in our daily lives it doesn’t matter which exact material collection
  441. 31:51we mean when we say “this chair.”
  442. 31:53However, let’s go back to our cranes.
  443. 31:59When we talked about holes we said that holes might be ONTOLOGICALLY parasitic.
  444. 32:04That their existence seems to require the existence of something ELSE: something that
  445. 32:09can HOST the hole.
  446. 32:12Perhaps this crane is holey, too.
  447. 32:16Not a physical thing in its own right, but a disturbance IN some paper.
  448. 32:21There is no material crane here, there is only some paper that is arranged crane-wise.
  449. 32:26But once we start entertaining that notion, we realize that nearly EVERYTHING we see and feel
  450. 32:31all ordinary obejcts and even ourselves are ontological parasites
  451. 32:38Michael Jubien calls our tendency to think that what is true of a “chair” is true
  452. 32:42of the material that is chairing OBJECT FIXATION or PROPERTY REPRESSION.
  453. 32:49Object fixation is useful and “nearly as good as true” but when paradxoes loom, we
  454. 32:55should remember that while chairs exist, they aren’t made out of matter and can’t be
  455. 33:01touched or or felt or tasted.
  456. 33:04All I can do is taste some stuff while it chairs.
  457. 33:08If it looks like a duck, swims like a duck, and quacks like a duck, then it’s not a
  458. 33:14duck, but it is arranged duck-wise.
  459. 33:18I think that the only concrete physical things in our universe are simples — or, since
  460. 33:25our universe could be gunky — the material world only contains stuff.
  461. 33:31And yes, this stuff is chair-ing, but the road paved by the idea that that makes this
  462. 33:37stuff A chair leads to paradox.
  463. 33:41To see how we could have made that mistake, let’s remember the famous Clintonian dictum
  464. 33:45that often “it depends on what the meaning of “is” is”
  465. 33:51There’s the “is” of predication, which tells us what some thing is like, as in, this
  466. 33:57cheese IS floppy.
  467. 34:00And then there’s the “is” of identity which tells us what is the same as what for
  468. 34:05example, 2+2 IS 4.
  469. 34:09To believe that chairs are made of matter — to be believe that YOU are made of matter
  470. 34:14— is to confuse these two ISes.
  471. 34:18When a collection of properties are extremely thorough in telling us what to expect from
  472. 34:22some stuff, we tend to just go ahead and NOUN them: collapse them into a single word and
  473. 34:28believe it doesn’t just describe some stuff, but REFERS to it.
  474. 34:34I think we have an intuitive sense of the thoroughness of properties and this can be
  475. 34:38seen in how we order our adjectives.
  476. 34:41“Big” can mean many things.
  477. 34:44A big diamond and big house are very different in size.
  478. 34:49“Blue” tells me a bit more about what to expect, but CHEESEBURGER, oooh that’s
  479. 34:55specific.
  480. 34:56So specific, in fact, that we call it a noun.
  481. 35:00This increasing thoroughness may be partly responsible for the fact that “big blue
  482. 35:05cheseburger” sounds fine, but blue big cheeseburger” sounds kind of weird.
  483. 35:12When we embrace the idea that cheseburgers are not physical objects, but instead, exist
  484. 35:18as an abstract set of properties like juicy, warm, soft, and so on, the specter of ontolgical
  485. 35:25paradox dissipates.
  486. 35:28You and I are not physical objects either.
  487. 35:32“Michael-ing” is a bunch of different properties and most of them are very vague.
  488. 35:37They include things like, “knowing who Kevin is, being more or less a certain height, having
  489. 35:43a roughly continous relationship with the stuff that Mcihaeled yesterday and that that’s
  490. 35:46Michael-ing today” and so.
  491. 35:48Some of what it means to Michael does concern composition, like, the fact that I will still
  492. 35:54exist even if I shave off the stuff I call my beard.
  493. 35:58If I shaved off my beard, there would still be some stuff Michael-ing, but it would be
  494. 36:03different stuff than before.
  495. 36:05We’re able to lose parts and change and grow because we aren’t made of matter, we’re
  496. 36:15hosted by matter.
  497. 36:16There’s no thing that is you and no thing that is ME.
  498. 36:18As Alan Watts would say, the universe doesn’t contain people, the universe PEOPLES.
  499. 36:24Chairs and tables and rocks and buckets and people are not made of atoms, they are preformed by atoms.
  500. 36:33We are disturbances in stuff and none of it is us.
  501. 36:40This stuff right here is not me. It's just me-ing.
  502. 36:44We are not the universe seeing itself, we ARE the seeing.
