Kind: captions Language: en the following is a conversation with zev weinstein a young man with a brilliant bold and hopeful mind that i had the great fortune of talking to on a recent afternoon he happens to be eric weinstein's son but i invited zev not because of that but because i got a chance to listen to him speak on a few occasions and was captivated by how deeply he thought about this world at such a young age and i thought that it might be fun to explore this world of ours together with him for time through this conversation quick mention of our sponsors expressvpn grammarly

forward to change his mind publicly to learn to articulate difficult nuanced ideas and grow from the conversations that follow in this i hope he leads the next generation of minds that is joining and steering the collective intelligence of this big ant colony we think of as our human civilization if you enjoy this thing subscribe on youtube review it on apple podcast follow on spotify support on patreon i'll connect with me on twitter lex friedman and now here's my conversation with zev weinstein you've said that philosophy becomes more dangerous in difficult times what do you mean by that interestingly i think i mean two things by that and i think firstly i should clarify when i say philosophy i sort of mean in a very traditional sense just thinking ideation and that could be reconsidering our notions of self in a very traditional sense which we consider philosophy or that could be like technological uh innovation i think it's important to recognize all of these as philosophies that we can not question whether it's important to promote thought i think the other thing i should clarify is when i say difficult times i mean times when nothing is growing and so the risk for real conflict is much greater because people are incentivized to fight over the things which already exist i think when times are not difficult the people with the greatest power are usually the people who are very creative generating a lot and that really requires ideation or philosophy of some sort i think when times become stagnant the important successful people become the people who are very good at protecting their own pieces of the pie and taking others um i think that those people have to be very opposed to any sort of thinking that could restructure society are conventions about who should succeed and so firstly i mean by that that it becomes much more dangerous dangerous for a person to think deeply and question during a time when the important people or those concerned with making sure no one rocks the boat you know one example of this would be like socrates and his execution because everyone was happy enough to sit through his questions before uh there was war and poverty and distress and afterwards it just became too dangerous the other thing i mean by that is that the consequences of thinking deeply carry much greater potential for real catastrophe when everyone is desperate so like for example you know the communist manifesto was probably much more dangerous during early 1900s russia than it was during the 1848 revolutions because i think people were in much worse shape and desperate people are very willing to dive into anything new that might bring the future without fully calculating whatever the consequences or risks might be so it is both more dangerous for a person to have creative ideas and those ideas are more dangerous when when times are tough and by dangerous you mean it challenges the people with power who don't who want to maintain that power in times of stagnation when there's not much growth innovation creativity all that kind of stuff right and we know that if nothing new is created people have promises that they've made about what will be paid to whom what debt structure is the only possibility if stagnation lasts for long enough is really some kind of great conflict great war because people have to take from others to make good on their own promises so we know that by denying any sort of grand ideation we are accepting that there will be some kind of great catastrophe and so we have to understand that philosophy is the most important uh when we've seen too much stagnation for too long it is also very dangerous and it's dangerous for the people who are doing it and it's dangerous for the people who believe it but it's kind of our only way out ever and again by philosophy you mean the bigger this is not academic philosophy or this kind of uh games played in the in the space of just like moral philosophy and all those metaphysics all that kind of stuff you mean just thinking deeply about this world thinking from first principles i think your like twitter line involves something about like trying to piece everything together in first principles so that's that's fundamentally what uh being philosophical about this world is and that's where the people who are thinking deeply about this world are the ones who are feeding who are the catalysts of this growth in society and so on yeah i i mean i also think that the real implication of moral philosophy can be something that most would consider like a real political uh implication so i think all philosophy really ties together uh because there has to be some sort of grand structure to all thought and how it relates do you think this growth and innovation and improvement can last forever we've seen some incredible you know the things that humans have been able to accomplish over the past several hundred years is just i mean awe inspiring and every moment in that in that history it almost seemed like no more could be done like we've we've solved all the problems that are to be solved and there's just historically there's all these kind of ridiculous like bill gates style quotes or like it's obvious that we've uh this new cool thing is not going to take off and yet it does and and so there's there's a feeling of the same kind of pattern that we see in moore's law there's constant growth and different technologies in the modern day era in any kind of automation over the past 100 years do you think it's possible that we'll keep growing this way if we give power to the philosophers of our society i think the only way that we can keep growing this way is if we give power to real thinkers and there's no guarantee that that will work but we sort of don't have any other choice and i think you're entirely right that this period of both understanding the universe at a rate which has has never been seen before and invention and creativity that these past hundred years have been sort of uncharacteristic uh for the level of growth that we've seen not in all of history we've never seen anything like this and i think a lot of our a lot of our promises rest on this sort of thing continuing i think that's very that's very dangerous but the one thing that can get us out of this is philosophy and being ready to radically restructure all of our notions about what should be what is i think that's very important so you think deeply about this world you are clearly this embodiment of a think of a philosopher your dad is also one such guy eric weinstein do you just do you have big disagreements with him on this topic in particular i think now people should know he also happens to be in the room but uh the mics can't pick him up so he can uh heckle it doesn't even matter but do you have disagreements with him on this point let me um try to summarize this argument that we were actually based a lot of our american society on the belief that things will keep growing and yet it seems that however you break it apart maybe from an economics perspective that they're not growing currently and so that's where a lot of our troubles are at do you have the same sense that things there's a stagnation period that we're living through over the past couple of decades i think stagnation modern stagnation is completely undeniable particularly scientifically and i think there have been a few fields where tremendous progress has been made very recently i think my dad might feel that uh there is sort of an inevitability to the ending of this period and i'm not so certain so certain that uh the fall of this great time is completely inevitable because i don't know what thoughts we're capable of producing what we're able to reconsider i think we really have to be open to the possibility that uh all of our standard frameworks where you know like he will talk about embedded growth obligations if we continue within the same framework then we're very susceptible to the dangers of whatever these embedded growth obligations are i think if we break the frameworks we have no reason to believe that the problems we're experiencing with our current frameworks will will follow us and i think that's the importance of radical thought is we don't know what the solution is but if there is a solution it will be born from some very fundamental thinking and so i've i have great hope so you have optimism about sort of the power of a single radical idea or a single radical thinker to break our frameworks and uh break us out of this like uh spiral down due to whatever the the economic forces that are creating uh this current stagnation yeah i'm very very hopeful the optimism of youth well i share uh i share your optimism so let me let me come back to something you've also talked about you have very little stuff out there currently but the things you have out there your thoughts you could just tell how deeply you think about this world and one of the things you mentioned is as you learn about this world is that you as you read as you sort of uh go through different experiences that you um that you're open to changing your mind how often do you find yourself changing your mind do you think zev from 10 years into the future will look back at like at this conversation we're having now and uh disagree completely with everything you just said it's entirely possible and that's one of the things that scares me so much about appearing publicly i think that the internet can be very intolerant of inconsistency and i am entirely prepared to be very inconsistent because i know that whatever beliefs i have when subjected to scrutiny may change because that's that's really the only way to to form your truest most fundamental conceptions about the world around you and it would take an infinite amount of time to subject every single one of your beliefs to scrutiny and so that's a a process that must follow me throughout my entire life and i know that means that my opinions and perspectives are always to be changing i'm prepared to accept that about myself whether other people are prepared to accept that my uh public opinions may may change and vary greatly over time is something i i don't know i don't know how tolerant the the world will be but i'm very prepared to change anything i i believe in if i think deeply enough about it or a good enough argument is made so that i i might reconsider well that's there certainly is currently an intolerance and that's what the one of the problems of our age there's an intolerance towards change and i'll also ask you about labels you talked about so we like to bend each other into different categories blue or red or whatever the different categorization is but it seems like the task before you as a young person defining our future is to make a tolerance of change the the norm doing this podcast for example and then changing your mind one or two years later and doing so publicly without a big dramatic thing or maybe changing it on a daily basis uh and just being open about it and being transparent about your thought process maybe that is the beacon of hope for the philosophical way uh the path of the philosopher so that's your task in in a sense is to change your mind openly and bravely you know you're right and maybe i will just have to endure some sort of criticism for doing that but i think that's very important i think this ties back to this previous facet of our conversation where we were discussing if uh you know thinkers would win over systems that are devoted to preventing radical thought or if uh you know who will win the the systems or the or the thinkers i think it's crucial that my generation uh take up a hand in this fight and i think it's important that i'm a part of that because i know that i have some opportunity to um there is i think it is my obligation as a member of a generation whose only real hope is to think outside of a system because whatever systems exist are collapsing i think it is really my my obligation to try to play some role whatever role i can and being an instrument uh in in that change are you uh as a young mind do you have a sense of fear about just like how afraid were you to do this podcast conversation do you have a sense of fear of thinking publicly yeah i i don't even think that that fear is irrational it's very difficult to exist publicly in any form now because it's very easy for anyone to take cheap shots at something which is difficult and as i said the people who are trying to have the difficult ideas and conversations are perhaps putting others in in actual danger because everyone is so desperate that they're they're they might be they might be willing to to try anything so um there's a certain amount of responsibility which one has to take going before the public and there is a certain amount of uh ridicule which will be completely unwarranted that anyone must endure for it um and i think that it means that the one has to be afraid because they could both ruin the world and be ruined by the world in in an unwarranted and undeserved fashion um i would like to believe in myself enough to try to accept this as a task because i think people need to try or there's no getting out of this and we will end in some kind of crazy brilliant war awfully put you've said also that uh in these times we can't have labels because it holds us holds us back maybe we've already talked about a little bit but this idea of labels is really interesting uh why do you think labels hold us back well i think many underestimate the extent to which language and communication really impacts and shapes the ideas and thoughts which are being communicated and i think if we're willing to accept uh imperfect labels uh to categorize particular people or thoughts in some sense we are corrupting an abstraction in order to represent it and communicate about it and i think as we've discussed those abstractions are particularly important when everything is on fire um we should not be sacrificing uh grand thought for the ability to express it i think everyone should work much harder including myself to really be thinking abstractly in abstract terms instead of using concrete terms to discuss abstraction while ruining it slightly yeah it's uh it's kind of a skill actually so one one really difficult example of in this uh in the recent time that maybe you can comment on uh if you have been thinking about it is just politics and there's a lot of labels in politics that it takes a lot of skill to be able to communicate difficult ideas without labels being attached to you that's something i've been sort of thinking about a lot in uh trying to express for example how much i love various aspects of the foundational ideas of this country like freedom and just saying i love america as a simple statement i love the ideas that we're finding to america will often in the current time well people will try to desperately try to attach a label to me for example for saying i love america that i'm a republican a donald trump supporter and it takes elegance and grace and skill to like to like avoid those labels so that people can actually listen to the contents of your words versus uh the summarization that results from just the the labels that they can pin on you are you cognizant of the skill required there of being able to communicate without being branded the republican or democrat in this particular set of conversations i'm sure there's other dangerous labels that could be attached i don't think there's any way of avoiding that right now it might not be anyone's best effort to really try i think the thing i can say which will most speak to that which i truly believe is that participating in modern conventional politics is not being inherently political in a generative sense it's it's this it's this repeated trope where politics now is not about creating new political ideologies it's about defending ideologies which already exists so that everyone can keep what they have and that's where all of the the name calling and the labeling really comes in it's an attempt to constrict whatever may be generated to standard conversations and discussions so that arguments can be strawmanned and defeated and people can keep what they have because everyone's very very scared i want to be very political but not in a standard political sense where i'm defending a particular party or place on a on a spectrum i would like to play some role in inventing new spectrums and i think that's most important politically because above most else politics is about real power and conventional politicians have real power uh and that power will find terrible outlets if new spectrums for that power to live are not invented so so you're not afraid of politics political discourse at the deepest richest uh level of what political discourse is supposed to mean actually i'm i'm very afraid of it but once again we we have no it's not paralyzing for you that you feel like it's a responsibility you're ready to take it on yes this is a good sign this is uh you're a special human okay let's talk uh maybe fun maybe profound uh we talked about philosopher's philosophy uh who's your favorite philosopher who like somebody in your current time been either influential or you just enjoy uh his her ideas or writing or anything like that weirdly i'll i'll give an answer which sort of doesn't have much to do with whom i might imagine myself to be i like thomas aquinas at the moment i think he's very inspirational to me given what we're going through and that's not because his particular ideas of religion or god or unmoved movers are particularly uh inspirational to me and they i don't even think they were necessarily right um but he was introducing aspects of the scientific method during one of the darkest periods in human history when we had lost all hope and reason and ability to think logically so i think he was really something of a light in the dark and i think we need to look to people like that at the moment the other reason why i think i need to uh need to learn from him is that even though he was doing something which really needed needed to be done and uh introducing scientific thought and reason to a time that that lacked it um he was not saying anything that would have been offensive to whatever powers were in play during his time he was writing about you know the importance of of faith in god and how we could prove it and so it's important to remember i suppose that having ideas that shape the world and which bring the world closer to what we can prove it's supposed to be and how it's supposed to work does not always take some sort of grand contradiction of whatever is in play and the most courageous thing to do may not always be the most helpful thing to do and i think it's it's very easy for anyone with uh ideas about how everything is is broken to become very cynical and say oh the system man they're they're all wrong yeah um i think it takes another kind of discipline to be a person with real ideas and to make the world better without stepping on anyone's toes or contradicting anyone i have real respect for that so being able to be when it's within your principles to operate within the current system of thought yeah and not not offend anyone not say anything outlandish but introduce the method by which progress must be achieved i think that takes a kind of maturity which is found very rarely uh now and i really look to him for inspiration despite whatever disagreements i may have with the my new details of his philosophy yeah it takes a lot of skill a lot of character and yeah deep thinking to be able to operate within the system when needed and having the fortitude and just the boldness to step outside and to burn the system down when needed but rarely and opportune moments that would actually have impact i mean it's ultimately about impact within the society that you live in not just making a statement that has no impact yeah and we were talking about how dangerous it is to do real philosophy at dangerous broken times he was going through the most broken time in history and he questioned the the methods which made a broken system uh able to survive and he was so skilled and so graceful that he became a saint in that tradition and there's something for me to really learn from there do you draw any inspiration have any interest in the sort of more modern philosophers maybe the existentialists i mean nietzsche is one of the the early ones do you have thoughts on the guy in general or any of the other existentialists well with regard to nietzsche i think i think yates might have said that he's the worst you know he was it was certainly filled with with passionate intensity um is that a compliment he was the worst or uh or her criticism yates said this has this big line the the best lack all conviction the worst are filled with passing passionate intensity um so um i think nietzsche was was destroyed by the the horrors of everything that uh that went on around him and i think he never really recovered from it i think that's because if you think about nietzsche's philosophy he was very opposed to any sort of acceptance of what one had one should always envy those who have more and use that envy to uh to fuel their their growth and become you know accept whatever the the human condition and desires are and use use those desires to want more and more and and make use of your greed i think it's very difficult to be truly happy if the thing which you uh the thing which you pride yourself most on is uh never being satisfied and i think nietzsche was never satisfied and that was the the danger of his philosophy i think also with his immoralism you know there is no good or evil i sort of disagree with that on a pretty fundamental basis i think that um our notion of morality is by no means subjective it's really the proxy for the fitness of a society i think whatever we consider ethical like don't steal don't murder don't do this societies have a very difficult time running it's very hard to run a civilization when everyone is stealing from everyone else and people are murdering each other and committing these things which we would consider uh atrocities so i think we also we know this because i think very similar notions of morality have evolved convergently from different traditions i think good is a proxy for a civilization's fitness and the good news is that that means that evil in being anathema to that good uh must therefore be uh the opposite of stable in whatever way that it's evil and that means that good will always be more stable than evil and the only way evil can really win is like if everyone dies so um so wait uh can you say can you say that again good is a proxy for society's uh what good is a proxy for the stability and fitness of the civilization i believe and you know that's a good definition thank you so you're throwing some bombs today okay all right okay um this is exciting sorry sorry interrupt your uh flow there but just a good damn good one thank you uh so in that sense that's kind of optimistic view that if by definition good is a proxy for stability then it's going to be stable unless the entire world just blows itself up so good wins in the end by definition yeah or uh no actually well good wins unless it all goes to uh complete destruction beauty that's a beautifully put thank you on the topic of um sort of you know good in evil being human illusions you've said that uh more broadly than that about truth that it is easier in some ways to be unified under truth because it is universal than it is to be unified under belief which at times can be completely subjective so what is the nature of truth to you can can we understand the world objectively or is most of what we can understand about the world is just uh subjective opinions that we kind of all agree on in these little collectives and over time it kind of evolves completely detached from objective reality i think this is the greatest argument for objectivity uh is that something that is objectively true cannot be true to me and untrue to to you you can feel that it's that it's untrue but that would be uh unproductive and create unnecessary tension and conflict i think this is one reason for the importance of science as a tool for stability if science is the search for truth um and truth can never really be i shouldn't say that truth should never be an engine of conflict because no two people should disagree on something which is objectively true then in some sense search for truth is searching for a common ground where we can all exist and live without contradicting or attacking each other do you ever hope that there is a lot of common ground to be discovered sure i mean if we continue scientifically uh we are discovering truth and in that discovering common ground on which we can all agree that's that's one reason why i think uh caring about science if you have a culture which cares very deeply about science that's a culture which is not necessarily bound to injure unwarranted internal conflict i think that's one reason that i'm so passionate about science is its search for universal ground let me just throw out an example of a modern day philosophical thinker will keep your uh dad eric weinstein out of the picture for a sec but he does happen to be an example of one but jordan peterson is an example of another somebody who thinks deeply about this world um his ideas are by certain percent of the population sort of speaking of truth are labeled as dangerous why do you think his ideas or just ideas of these kinds of deep thinkers in general are labeled as dangerous in our modern world is it similar to what you've been discussing that in difficult times philosophers become dangerous was there something specific about these particular thinkers in our time well i think jordan peterson is very anti-establishment in a lot of his uh beliefs he's an unconventional thinker and i think we need regardless of whatever uh jordan's particular views and beliefs are and if they uh bring about more danger than uh truth or uh if if they don't it's very important to have fundamental thinkers who exist outside of a conventional framework so do i think that he's dangerous i think by existing outside of a system which is known he is dangerous and i think we have to in some sense we have to welcome danger in that capacity because it will be our only way out of this so i'm regardless of whether his beliefs are right or wrong i am pretty adamant about the fact that we need to support um thought which may rescue us and that thought can appear radical or dangerous at times but ultimately if you allow for it this is kind of the difficult discussion of free speech and so on is ultimately difficult ideas will pave the way for progress yeah and i'd actually i'd like to to slow you down there because i think like one of the issues we were discussing previously was the fact that language often destroys our ability to think um when we're talking about whether his ideas are a radical i don't know if we if we mean radical in the traditional sense of having to to do with the root of a problem or in the more modern sense of being um very extreme and i think that's completely by design i think fundamental thought which semantically would once be considered radical thought became very dangerous and now it's become synonymous with extreme or dangerous thought which means that anyone who considers themself a radical thinker is semantically also a dangerous or extreme thinker these are not helpful labels in a sense that the moment you say radical or extremist thinker then you're just uh well how do i put it you're not being you're not helping the public discourse exchange of ideas but through no fault of our own the concept of radical as having to do with a root is uh it's a it's an obvious concept for which there must be language and a lot of the attack on thought has to do with attacking language which communicates conceptually so like this is an example of how our world is becoming increasingly orwellian it's just language is being used to destroy our ability to uh to think i think i can't remember exactly what the numbers are but i read some statistic about how greatly the average english vocabulary has decreased since 1960. it was like some incredible number it really baffled me it's like how are how are people less able to to think in a time when the world is supposed to be growing at a never before seen rate it's like we can't keep on we can't sustain this growth if we destroy everyone's ability to think because the growth requires thinking and we're we're ruining the tools for it i watched your uh your podcast with noam chomsky and i i think one interesting thing which he discussed was how language is more used to develop thoughts within our own head than it is used to communicate those thoughts with others if the language doesn't change even if its usage changes then when language is destroyed in communication it also stymies our ability to to think reasonably and i'm very very worried so but the language in communication uh requires a medium and there's a lot of different mediums so there's uh social media there's twitter there's uh writing books there's blog posts there's um podcasts there's a youtube videos all of things you have uh dipped a toe in in your exploration of different mediums of communication yeah which do you see yourself this might be just a poetic way of asking are you going to do a podcast but a broad broader picture what do you think as an intellectual in this world for you personally would be the path for communicating your ideas to the world what are the mediums you you are currently drawn to out of the ones i mentioned maybe something i didn't to answer your your question concretely before uh abstractly uh i'm scared but i need i need to do a podcast you know it's it's important it is my obligation as a member of my generation i i really hope that more people my age start to do this because we will be the people in charge of new ideas which either sink or uh or swim how upset would your dad be when your podcast quickly becomes more popular than his i think he would be negatively upset also you'd be proud he's a good dad i i really think so yeah sorry to interrupt uh uh yes so but then zooming out do you think podcast are you excited by the possibility of other mediums outside of podcasting to communicate ideas i would be if people still read books or did things like that uh i'm somewhat guilty of this a lot of the books i i read are um very technical and then my to absorb like really deep modern conversations i listen to uh i listen to podcasts and i don't really read many uh books on like the matters that we're discussing for example it's fascinating because you're making me think of something um that i align with you very much of how i consume deep thinkers currently so what happens is somebody who thinks deeply about the world will write a book jordan penis an example and instead of reading their book i'll just listen to podcast conversations of them talking about the book which i find to this is really sad but i find that to be a more compelling way to think about their ideas because they're often challenged in certain ways in those conversations and they're forced to after having boiled them down and really thought to them enough to write a book so it's almost like they needed to go through the process of writing a book just so they can think through convert the language in their minds into something more concrete and then the actual exchange of ideas the actual communication of ideas with the public happens not with the book but after the book with that person going on a book tour and communicating the ideas well there are two meanings i i make of why not too many people spend much of their time reading anymore one one interpretation is that we've lost our attention spans to our phones people can't concentrate on a page if it takes them a minute to read we're too busy you know watching tech talks or whatever people do the other interpretation would be that language and verbal communication has as well as you know some amount of communication which is done through you know facial expression uh tone of voice etc these are means of communication that have evolved along with humanity over thousands and thousands of years so um we know that we are built to communicate in this way uh we have had writing for much less time it is a system that we invented not a system which evolved and is innately part of uh you know humanity or the the human mind um and so we are designed to consume conversation by our own evolution we are designed to consume writing by some process of symbols that's evolved over a couple thousand years it makes sense to me why many are much more compelled to listen to podcasts for example than they are to read books it could be that this is simply a technological uh progression which has displaced uh reading conventionally instead of some sort of maladaptation of our minds which has corrupted our attention spans and likely there's some combination which determines why people spend much less time reading but i don't think it's necessarily because we're all broken it may simply have to do with the fact that we are designed to listen and through our ears and speak through our mouths and we are not innately designed to communicate uh over a page so yeah there's an exciting coupling to me between like a few second tick tock videos that are fun and addicting and then the three four hour podcasts which are both really popular in our current time so people are both hungry for the visual stimulation of internet humor and memes a huge fan of and also slow moving deep conversations and that might you know it's there's a lot of i mean it's part of your generation to define what that looks like moving forward where a lot of people like joe rogan is one of the people that kind of uh started accidentally stumbled into the discovery that this is like a thing yeah and now people are kind of scrambling to figure out why is this a thing like why is there so much hunger for long-form conversations and how do we optimize that medium for further further expression of deep ideas and all that kind of stuff and youtube is a really interesting medium for that as well like video sharing of videos mostly youtube is used with the spirit of like the tick tock spirit if i can put in that way which is like how do i have quick moving things that even if you're expressing difficult ideas they should be quick and exciting and visual and switching but there's a lot of exploration there to see what can we do something deeper and nobody knows and you're part of the you have a youtube channel uh releasing one video every few years um so so your momentum is currently quite slow but uh perhaps it'll accelerate but you're you're uh you're one of the people that gets to define that medium is that do you enjoy that the visual the youtube medium of communication as well i know that when the the topic of conversation uh or the the means by which a conversation is is communicated or an idea is communicated if that is sufficiently interesting to me um i will read a book on it i would listen to a podcast on it i would watch a video on it i think if i'm very curious about something i will consume it however possible i think when i have to consume things which really don't interest me very much uh i'm indeed much more ready to consume them through some sort of video or discussion than i am through like a long tedious book so for the the for the breadth of uh acquiring knowledge video is good for the depth the medium doesn't matter i think it'd be fun to ask you about some big philosophical questions to see if you have an opinion on that do you think there's a free will or is free will just an illusion well i think classical mechanics would tell us that if we are if we were to know every piece of information about a system and understand the rules which govern that system we would be completely able to predict the future with complete accuracy so if something could know everything about our lives it could freeze time and and understand the position of every neuron in my mind about about to fire um no decision could be uh unpredictable there in some sense there is that sort of uh that sort of fate i think that doesn't make the decisions we make illegitimate even if some grand super computer could understand what decisions we would make beforehand with complete certainty i think we're making legitimate systems uh within a system that has no freedom we're making legitimate systems within a system that has no freedom can you explain what you mean by that yeah so if we were to have uh just a simple pendulum and i told you how long the the rope was i i we froze it at a particular uh point and i told you how high high above the ground the weight was and uh you know the motion of a of a pendulum is something which is it's easy for everyone to imagine um i could if we had all of that information you could ask me where will the what will the pendulum do six and a half minutes from now and we would have a precise answer that's like a that's an example of a very simple system with a very simple lagrangian um and we could completely predict the the future that the pendulum has no ability to do anything that would surprise us weirdly that's true of whatever this four-dimensional crazy world we live in looks like if we were to if we were to understand where every piece of this system was at any given time and we we understand the the laws of motion how everything worked if we could compute all of that information somehow which we won't never be able to do uh we would every decision you you will ever make could be predicted by that computer that doesn't mean that your decisions are illegitimate you are really making those decisions but with a completely predictable outcome so i'm just uh sort of a little bit high at the moment on the uh on this on the poetry of a system within a system that has no freedom so the human experience is the system we've created within the system there's no freedom but that system that we've created has a feeling of freedom that to us ants feels as uh much more real than the the physics as we understand it of the underlying like base system so it's almost like not important what the physics of the base system is that for the what we've created the nature of the human experience is uh there is a free will or there's something that feels uh close enough to a free will that it may not be uh worth uh spending too much time on the fact that it's something of an illusion we will never build a computer that knows everything about every piece of the universe at a given time uh and so for all intensive purposes uh our decisions are up to us we just happen to know that their outcomes could be predicted with enough information so um speaking of super computers they can predict every single thing about the uh what's going to ever happen uh what do you think about the philosophical thought experiment of us living in a simulation do you often find yourself pondering of us living in a simulation of this question do you think it is at all a useful thought experiment i think it's very easy to become fascinated with all of these possibilities and they're completely legitimate uh possibilities you know like do i is there some validity to like solipsism uh while it can never be falsified or disproven so i mean sure you could be a figment of my uh imagination uh it doesn't mean that i will act according to this possibility i'm not going to call you mean names and just to test the system uh to see how robust it is to distortions yeah so i mean all of these existential thought experiments are completely possible we could be brains and jars it doesn't mean that our experience will feel any less valid and so it doesn't make a difference to me if uh you were some number of of ones and zeros or you were a figment of my imagination which lives in a in a stored stored away brain uh it will never really change my experience knowing that that's a possibility and so i try to i try to avoid making decisions based on such contemplations you know if we take this this previous issue of free will um i could i could decide that because i have no choice in my life if i lie around in bed all day and eat chips i was destined to do that thing and if i make that decision then i was destined to do that thing it would be a really poor decision uh for me to make i have school and a a dozen commitments uh there's somebody listening to this right now probably hundreds of people sitting down eating chips and feeling terrible about themselves those are how dare you sir if they're listening to this they're purely they're clearly curious about um possibilities of of thought it's not the it's not the bed and the chips that okay it makes the man it's not the better the chips the makes man yet another quotable from zev weinstein okay uh but you don't think of it as a useful thought experiment from an engineering perspective of you know virtual reality of thinking how we can create further and further immersive worlds like would it be possible to create worlds that are so immersive that we would rather live in that world versus the real world i mean that's another possible trajectory of the world that you're growing up in is where more and more immersing ourselves into the digital world for now it's screens and looking the screens and socializing the screens but it's possible to potentially create a world that's also visually for all of our human senses as immersive as the physical world and then you know it's to me it's an engineering question of how difficult is it to create a world that's as immersive and more fun than uh the world would currently live in it's a terrifying concept and i hate to say it we might live happier lives in a virtual reality headset 30 years from now then we are currently living this future the digital future worries you it worries me on the other hand it may be it may be a better alternative to um fighting for whatever people are clinging on to in our non-virtual world or at least the world that we don't yet know is virtual so embrace the future we've been talking a lot about thinkers now in the broad definition of philosophy you kind of included innovators of all forms do you find it useful to draw a distinction between thinkers and doers i think that the most important gift we've ever been given is our ability to observe the universe and think deductively about whatever principles transcend humanity because you know as we discussed that's that's the closest thing we will ever have to um a universal experience is understanding things which must be true um everywhere in order for that so i think if if we're if we're deciding that that life is is meaningful and the human experience is meaningful uh you could make a very convincing argument that its greatest meaning will be understanding whatever transcends it um i think that's only sustainable if people are happy and well fed and things of of market value are invented and so i think we really need both to live meaningful and successful and possible lives in terms of like who who my greatest heroes are i can't decide between figures like uh einstein and newton and feynman and on the other hand figures like carrie mullis for example i think people like einstein make our lives meaningful and people like carrie mullis who's probably responsible for saving hundreds of millions of lives make our make our lives possible and uh good so in terms of where i would like to find myself uh with these two different uh notions of achievement i don't know what i would more like to achieve i have an inclination that it will be something scientific because i would like to bring meaning to humanity instead of uh sustenance but i think both are very important we can't we can't sustain our lives if we don't keep growing technologically i think people like you are making that possible with uh like computing because that's one of the few things that's really moving forward in a in a clear sense um i think i think about this a great deal so i think both are very important so one example that's modern day uh inspiring figure on the on the latter part and the engineering part on the sustenance is elon musk is that somebody you draw inspiration from what are your thoughts in general about the kind of unique speck of human that's creating so much uh inspiring innovation in this world so boldly i know that we will not survive without people like that um elon is a ridiculous and sensational example of one of these figures i don't know if he's the best example or the worst example but he is he is of his own kind he is radically individualistic and those are the people who will allow us to continue uh as as humans i'm very happy that that we have people like that in this world you said this thing about if we are to say that life has meaning our life is meaningful then you could argue that it is a worthy pursuit to transcend life do you see that another just i'm gonna have to i'm gonna have to go back um and sleep on that one uh do you do you draw some speaking of elon some inspiration of us uh transcending earth of us moving outside of uh this particular planet that we've called home for a long time and colonizing other planets and perhaps one day expanding outside the solar system and uh expanding colonizing our galaxy and beyond honestly i know very little about space exploration i think it makes complete sense to me why we are starting to think very seriously about it it's an amazing and baffling and innovative solution to a lot of problems we see as a world population i can't really offer very much uh of interest on the topic i think when i i'm talking about like transcending humanity and transcending earth i'm talking usually about deriving truth and that's one of the things that makes like theoretical math and physics so interesting it's like i i really really love biology for example but biology is a combination of whatever principles ensure evolution and whatever weird coincidences happened billions of years ago um so g is more interesting to understand the fundamental mechanisms of evolution for example than it is the results the messy results of its processes i can't say which is more interesting i can say which i think is more is more deep i think theory and abstraction which can be achieved completely deductively is deeper because it has nothing to do with circumstance and everything to do with uh logic and thought uh so like if we were ever to to interact with aliens for example uh we would not have our biology in common if if these were or some sort of really intelligent life form uh we would have math and physics in common because uh the laws of physics will be the same every everywhere in the universe our particular anatomy and biology pertains only to life on this on this planet and the principles may apply more ubiquitously do you ever think about aliens like what they might look like i try to when i i deal with thought experiments like these i try to keep a very abstract mindset and i notice that whenever i try to instantiate these abstractions i i corrupt whatever thoughts uh there are for which they're useful so it's kind of like the labels discussion so like the moment you try to make it concrete it's probably gonna look like some cute version of a human a big like it's the little green fellas with the eyes and so on or whatever whatever the movies uh have instilled like your cultural upbringing you're going to project onto that and the assumptions you have it's interesting so you prefer to step away and think and abstract notions of what it means to be intelligent what it means to be a living life form and all that kind of stuff i try to i almost try to pretend i'm i'm blind and i'm deaf and i'm only a mind with no inductive reasoning capacity when i'm trying to think about thought experiments like these because i know that if i incorporate whatever my eyes instruct my brain i will i will impede my ability to think as deeply as possible because once again it's the thing which shallows our thought can be the incorporation of circumstance and coincidence and for particular kinds of thought that's very important i'm not discounting the use of inductive reasoning in many humanities and in many sciences but for the deepest of thoughts once again i i feel it's important to try to transcend whatever uh methods of observation characterize human experience see but within that that's all really beautifully put i i wonder if there is a common mathematics and common physics be
