suspicious I don't find Chomsky's 21:56 argument at all compelling to say if I 21:58 can do one thing it therefore follows I 21:59 can't do something else that just 22:01 strikes me as being sophistry quite 22:02 honestly now you know there's an 22:05 interesting question how much we can 22:07 know about the physical I mean we've 22:09 several questions on the table and 22:11 people can take up with them but there's 22:12 a mind-body problem so if we know 22:14 everything about the physical world 22:16 would we then come to understand why 22:19 there's consciousness why there's a 22:21 mental world at all there's some people 22:24 who think physics just doesn't have the 22:26 resources to answer that question 22:28 there's a question of limitations of 22:30 physics itself right can we ever come up 22:33 with the right theory or are we just not 22:35 smart enough this is Stephen Weinberg's 22:37 problem it's like trying to teach 22:38 classical mechanics to a German Shepherd 22:41 you just can't get it right but we've 22:45 been very successful somehow with 22:47 physics I mean continue to be very 22:48 successful in at least producing a 22:50 physics that works tremendously well 22:54 can to know about the physical world we 22:57 have to interact with it in certain ways 22:59 and we can only find out as much as we 23:01 can find out that those interactions 23:02 allow so physics itself can put 23:05 limitations on what we can know about 23:06 the physical world right you can sort of 23:09 see the physics the physics of the world 23:11 might not allow us to know for sure what 23:13 the physics of the world is which is a 23:15 very interesting situation and you can 23:16 talk about cases like that and then 23:19 other cases I guess that people here 23:21 thought about the limitations of 23:22 mathematics because we use mathematics 23:24 has the language in which to state 23:27 physics so limitations in mathematics 23:28 our mathematical understanding lead to 23:31 problems but I guess I mean I think 23:33 these are all individually very 23:34 interesting questions but I do want to 23:36 push back against the idea that there's 23:39 some obvious reason to see that we're 23:42 going to bump up against some wall we 23:45 can't get beyond we might I mean we 23:47 ought to keep that in mind but I don't 23:49 see any reason to to you know convince 23:51 ourselves that we're perpetually limited 23:53 with respect to the things we want to

23:54 know ok ok my field is pure mathematics
