    About "Cogito ergo sum": 1: he did not write that in the Meditations, but in Discourse on Method, and 2: That book was actually in french, so the original quote is "Je pense, donc je suis". It's important, because it shows that Descartes actually believed his ideas should be spread wider than just the educated, latin-reading, elite.

      This. I was just about to comment on that myth. It goes from „je pense, donc je suis“ (1637, Discours) to „Ego sum, ego existo; certum est. Quandiu autem? Nempe quandiu cogito“ (1641, Meditations) and finally to „ego cogito, ergo sum“ (1644, Principles). So he actually wrote the latin version as well - but only 3 years later in a different book.

  • @johnc1014

    Here's a humbling thought: The more you understand, the more you realize how little you understand. A fool thinks they know everything, or at least that they know a lot. The wise understand that their knowledge is actually very limited. That last point (cogito ergo sum) actually makes a lot of sense. I ask: How can you be sure you are doubting; what if you are being made to only think you are doubting? And how do you know you are actually thinking? What if you are only being made to think you are thinking? Now, there's a problem. If you are being made to think you are thinking, then you are actually thinking. If nothing else, you can be sure of that: I think, therefore, I am. Wow, that makes sense!

      @igorpitty90 7 ปีที่แล้ว +24

      I came in the comments because I don't believe that the doubt, the thinking entails so surely my own existence. Then I saw your comment and it made me think about that problem, and I came up with one more doubt (that I address you, if you might):
      How can I be sure that this thinking that I think is mine is not actually some thinking that the Evil Genius of Descartes put in my mind? In this case, I would not being thinking that I am thinking, I would just being cheated by the Evil Genius. That is, why can't the "thinking" be some sort of an Evil Genius' trick?
      To illustrate this idea, imagine a videogame character that in some part of the game sit in a bench and start to think about his own existence, and doubting about it all. He clearly does not exist to the player as a person. How can we be sure that we're not in the same condition of that videogame character?
      Hank said "So Descartes decided that he couldn't know that he had a body - what he believed to be his body could've been part of the Evil Genius' deception. But he must have a mind, or he couldn't be having these thoughts", but according to the Evil Genius' definition (that Hank gave us), these "thoughts" we're having can be an Evil Genius' deception that we have no way of detecting this illusion.

    • @johnc1014
      @johnc1014 7 ปีที่แล้ว +45

      igorpitty90 "How can I be sure that this thinking that I think is mine is not actually some thinking that the Evil Genius of Descartes put in my mind?"
      Because the Evil Genius would be making you think that you are thinking, you would actually be thinking.
      You can say the Evil Genius tricked you in whatever way. But, the very fact that they would be tricking you points to a "you" whom can be tricked in the first place.
      . . . .
      "imagine a videogame character that in some part of the game sit in a bench and start to think about his own existence, and doubting about it all."
      Bad analogy - the videogame character has no capacity to actually think. They have no self-awareness at all. They are merely programmed to present an illusion of "thinking" to the player. But, they are not in existence any more than what is programmed and displayed to the videogame player.

    To be fair to Renee, even if he hadn't leapt to the conclusion that god exists based on him just really really wanting it badly, he would have had to do so anyway because the 1600s were not a safe space for radical thinkers. Safer than the middle ages, to be sure, but it's worth remembering that Descartes lived at the same time as the Thirty Years' War, a largely religious conflict so bloody and brutal that it nearly depopulated central Europe. Making enemies of both Protestants and Catholics by not rushing to a god-affirming conclusion could well have ended in tragedy for him.

    It's pretty common to see other people wondering, "Is anything I'm seeing real? Is all of it a stimulation?" and for that I too once wondered it a lot as a child. However, those thoughts also made me think about something similar.
    Sounds weird at first, but we know that most humans feel self conscious about being seen naked. In the shower (yes, shower thoughts), I kept thinking, "Despite the bathroom being closed in every way possible so there's no way for anyone to see me showering, what if there is someone still watching me but I'm just unaware of it?". That thought eventually turned into, "What if everything I'm seeing right now isn't real - perhaps an illusion or a stimulation -, but the actions I'm doing [In this case, showering] are still occurring in the 'real' world and that I'm just completely unaware of it?".
    And as a kid I kept thinking of this strange thought: What if what I'm seeing right now seems to be a normal life, but in reality I'm just a naked person in a cage, and every action I'm doing right now is happening in that cage. People walk by and think I'm crazy or have a problem. Perhaps it was just the paranoia or embarrassing myself without knowing, but it's quite crazy looking back and thinking, "Wow, I thought of THAT!"

    Dear Crash Course,
    I adore your work, but there's an inaccurate statement in this video:
    Descartes WAS NOT a Skeptic. He *Used a Skeptic Method* in the Meditations to prove that (1) God Exists, and that (2) The Soul and the Body are fundamentally separated. That's a huge and important difference.

    I hope you get a chance to explore some non-western thought, because one of my favorite ideas ever comes out of Buddhism, the idea of anattā (which I know Hank is at least somewhat familiar with). It runs exactly counter to "cogito ergo sum," because it means "no self." This is the idea that the self, the I, the ego, the soul, is an illusion.

      I had a nightmare once that I couldn't wake up and kept waking up falsely over and over and over and over. A hint to me that I was dreaming was that I couldn't turn any lights on. This caused me to panic and finally wake up. I've had this dream more than once. I just kept trying to turn the lights on each time I dreamt it until I stopped dreaming it.

    I have questions like that when I was little too, I doubt everything's existence and consciousness. When I learnt about Rene Descartes, it felt like I am finally understood. I concluded that if some people have the same thoughts as I do, they must be exist and conscious too.

    Cogito ergo sum (Je pense, donc je suis), I think therefore I am, is in fact from *Discourse on the Method*. From the Meditations, the quotation is: "After considering everything very thoroughly, I must finally conclude that the proposition, *I am, I exist (Ego sum, ego existo)* is necessarily true whenever uttered by me or conceived in my mind." (Meditatio II, line 10)

    • @NamelessBody
      @NamelessBody 7 ปีที่แล้ว

      Indeed. He spent a lot of time explaining why logic itself is unreliable, in his Meditations. Going on to then use a sentence that relies on the term "ergo" requies logic to function - ergo points to a deductive conclusion, but deduction has been previously doubted, because the manipulator could always manipulate you to believe that you had come up with a logical chain for arguments even though you have not, by messing with your memory midway through the thinking process.
      The "ego sum, ego existo" phrase no longer requires the use of logic (at least that's what Descartes appears to think), as it does not attempt to draw any conclusions - it is a mere observation without having to rely on any senses. Which, by virtue of being a sort of observation, ironically, is still somewhat empirical in my humble opinion, but that's a different argument.
      I think this is an important topic and should have received more screen time, at the expense of some of the basic explanation that was already done in the previous video.

    I remember when I was 12 yrs old I thought this:
    "I'm sure that I exist, but what about other people? Sure there are other people, but do they exist like I exist? Or they are just illusion God sent to me, like side-characters in one's story: I'm the main character, and they're side-characters. They don't matter, I matter."
    "What if the world isn't actually real, everything is not real. Like video games, you only know the things that are allowed by the gamemaker for you to know. Illusions."
    "What if our existence is a part of endless existences? We're the characters, and someone made us through another dimension, and someone from complex dimension made that someone that made us, and someone from far more complex dimension made someone from complex dimension that made someone that made us, and so on."
    I told my father about this, and he told me I played games too much XD

      And yes, even those doubts you had were also pondered about at that age. I still have those doubts. I often had an idea that only I existed and everyone else were just an illusion. But, I didn't tell anyone about this and now today I thank myself for not asking that. There's always that one person who says, " He's the Devil!" and the majority that says, " He's crazy". Xd

    Descartes exists as a thing, but not as a "thinking" thing. His thoughts could have been planted. All that he knows is that something exists, but what that thing is, or what it's capabilities are, are not actually known.
    He could be nothing but a tape recorder on loop, repeating to itself "i'm a thinking thing!", but that doesn't mean it's actually thinking. All it can solidly mean is that it exists.

    • @Mkill3rYT
      @Mkill3rYT 8 ปีที่แล้ว +8

      +roidroid His thoughts could have been planted by the "demon". The demon could be taping on his computer screen what I am thinking right now. But the question is : Where is he planting those thoughts ? It stills requier the existence of a consciousness to put the toughts into and so you can be aware of those thoughts.
      It doesn't really rules out the existence of consciousness but it does put a doubt on the validity of the toughts and the logic that's suppose to rule them.

      +roidroid He said "I think therefore I am." not "I am therefore I think."

      "Am I thinking? Or do I only think that I'm thinking? But in that case am I not thinking even if it's only thinking that I'm thinking?" was not what he was getting to.

    Descartes is one of the best examples to illustrate a general aspect of studying philosophy: We do not study the great philosophers because they were right about everything, but because the said something worse discussing, whether right or wrong. Either because they raised an interesting question, provided an interesting answer to a question or provided an interesting critique of an answer.
    Descartes had very debatable ideas for answering the challenge of scepticism and in other areas, his ideas have turned out to be flat out scientifically wrong (=> mind/body dualism), but his ideas were the foundation for so much worthwhile discussion.

    @amadaris78 8 ปีที่แล้ว +3

    Love the video and this series! Hate to dive deeper into the skeptic tank, but Decartes' famous, "I think, therefore I am" presupposes an "I" which is a kind of circular reasoning, and not as significantly 'Eureka!' as commonly portrayed. In order to have "I am" one must (according to Decartes) have "I think". In both cases, the "I" is presupposed to exist to lend qualification for the "think" and the "am". It is very similar to saying, "The Bible was written by God, and God exists because the Bible says so."
    Awesome video!

    "I think therefore I am" is actually considered begging the question since that statement is already assuming the "I" in the premise.

    How do you know that thoughts require a thinker? Is it really the "I" that thinks, or do thoughts come as they please to the I? Thoughts exist, and an "I" that on some level perceives these thoughts exists and feels that its its own, but it is possible to doubt the origin of thoughts imo.

      Hank skipped a step or two. You don't even need the evil genius: or rather, you could be your own evil genius.
      Maybe the world was created 5 min ago, but that still implies a world. Take it a step farther and doubt even that.
      Maybe you're a brain in a jar, and the world you know an illusion: that still implies a brain, a jar, and an illusionist.
      What if you're a mind in the void... Driven mad, engaging your own illusions like a daydream just to survive?
      Well... There we still must admit something exists- even if it's just you.
      We can doubt everything but one thing- because that must still be the source of the doubt- or more generically, any thought.
      If, as you say, that thought originates elsewhere, it still exists- it is self-proving... Perhaps the only thing that is self-proving.
      Whatever it originates from or interacts w/ then is also proven- after all, what does not exist cannot, by definition, interact with anything.
      Thus, you can at least prove yourself... If nothing else.

In all that time I have never been able to confirm anything beyond "I Exist". And I have actually found a potential flaw in the Descarte argument for self existence too.... So there is that. What I concluded is that, it doesn't matter. I can only attempt to function in the reality I perceive. I will do so. Regardless of how real or unreal that reality seems.

      +Mariana Farfán and if enough people keep saying this at each episode, they will end up doing it at some point after this series, hopefully.
      but they will probably give it a different name which will make it feel like euro philo is different (better/more important) than mid-eastern and Asian philosophy.
