    at 8:30, i think it can be argued that proposition 6 is analytic, for the temperature 100 degrees centigrade is by definition the boiling point of water. similarly, the temperature 0 degrees centigrade is defined as the freezing temperature of water. centigrade means 100 degrees, the 100 degrees between the freezing and boiling temperatures of water

    • @ravissary79
      @ravissary79 3 ปีที่แล้ว

      In a sense yes,but I suppose it could be falsified by adding salt. It would still be water, but it would not longer have the same boiling point, but that potentially creates a hidden imprecision of what defines water.

    • @saysHotdogs
      @saysHotdogs 2 ปีที่แล้ว

      It has to be synthetic since the only way to conclude the boiling point of water is by observing it and observation is sense data. But I think this follows the general idea of 2+2=4 and can be reconciled by placing it in the “synthetic a priori” category

    There should maybe be a distinction drawn between claims that are tautologous and claims that are a priori. Tautologies are trivial and follow from any given definition, a priori claims extend our knowledge in some fashion, they are arrived at through some level of analysis

    Here's an example I am struggling with discerning if it is "a priori" or what specific kind of reasoning I used. I heard I had a brother, and that was all the information I received about him. I was confident in thinking (believing) he is a good person, because I am a good person. This turned out to be true. Is this "a priori" , or what kind of reasoning did I use to arrive at this conclusion?

    There's a problem at 14:00 , you responded well that determinists would say that all the things you say here are contingent are in fact necessary, but the George Bush WAS president is contingent might be wrong from a presentist non-determinst from the perspective of the present... why? Because our present reality isn't a vantage point from which the past has any possibility of actually being different. We can say hypothetically, but then a Boethean who believes in free will can counter that HYPOTHETICAL I can go left or right at the stop light tomorrow morning, but it must be true, even now, that I WILL only go one way or the other and the other way I don't take has 0% chance of actually transporting, because in a B theory timespace there's the atemporal perspective by which I already did.
    I guess this gets messy because there's a category of necessity called contingent necessity, which covers former contingencies that are now foundational solid unchangeable realities which present to us a starting impetus for current contingencies, or materially necessary effects... in that sense a properly arrayed structure of dominoes only exists that way by past contingency, but once it does and the first domino is tipped, then the rest of the array falls "by necessity" despite the fact that everything else about the situation was previously contingent.
    Indeed this is a vital, not merely valid way of thinking of these things, as it pertains to cosmology and philosophy religion, because deteeminists believe the world unfolds by way of necessity, yet if they're divine determinists, they don't believe that the universe itself existing is itself necessary since God could have chosen not to create. But like the dominoes, if the universe is created by God's contingent will, in such a way that produces a fixed result, then the contingent universe becomes a system of necessity. God himself would be necessary for the contingent universe to exist, but God would act by contingency to create a system that follows by necessity.
    This interesting feature of necessity and contingency, trading places based on vantage point, is woefully underappreciated.

  • @diogenes3300

    Is ‘water is h20’ necessary because it’s a consequence of definitions? So perhaps that makes it analytic a posteriori.
    Analytic because it’s contained in the definition of water. You could change the word ‘water’ but not the necessity of its being h20. We don’t need to investigate all water molecules that exist. (h2o2 is hydrogen peroxide and no longer water). A posteriori because it’s not discoverable via thinking alone but needs observation.

    • @diogenes3300
      @diogenes3300 3 ปีที่แล้ว +1

      I may have to take this back. According to Kant, analytic judgements are not just consequences of definition, but “what has been already actually thought in the concept of the subject” (Prolegomena, 2). Since water being h2o must be discovered, it is not already thought into the concept of water.
      An example of an analytic judgment about water might therefore be, ‘Water is wet.’

    • @diogenes3300
      @diogenes3300 3 ปีที่แล้ว +1

      Elsewhere he writes that analytic statements are explicative (water is wet) and synthetic statements are ampliative (water is h2o); that is, it amplifies the concept.

    Thank you for the explanation! I just had a question about something being “necessary”: we believe that 2 + 2 = 4 because it cannot be contracted. However, what if I used a different number system? For example, what if I said 0010 + 0010 = 0100 in binary? Are both statements necessary, even though they contradict each other? Or is there no contradiction because I have acknowledged that binary is different since it has a different base number system (i.e., base 10 vs base 2)?

    are self evident things epistemically justified? if not then what is the nature of the justification by which they are justified? or they arent justified at all?
    can we justify a self evident claim by deductive argument? (i think with some claims we can & with some we cant)
    are they a priori/analytic?
    is it correct to say that the belief in the external world existing outside the mind was self evident until we came up with the brain in a vat scenario?

    2+2=4 is priori because it is mere of ideas
    2+2= 4 is analytic because the predicate(4) contains the subject(2+2)
    2+2=4 can be proven empirically therefore it is synthetic .
    Hence, Not all priori analytic are knowledge. Some priori analytic can be proven to be synthetic.
    Knowledge can be priori analytic and it can be priori analytic synthetic.

      You screwed up the second one, it is a priori if the predicated is contained within the subject, not if the predicate contains the subject. If the subject contains the predicated then no synthesis is needed to verify the claim made. Reason alone has the possibility to determine its truth, even if it can be also determined empirically

    What always confuses me is that you might say a priori doesn’t require experience but the thing is you still need experience to form the concept of the thing. Without the concept of a triangle how can you know it has 3 sides? You couldn’t conceive of a triangle unless you had the ability to think of one that, and that ability you probably get did from experience

  • @talismanskulls2857
    @talismanskulls2857 3 ปีที่แล้ว

    A priori seems to me to be nonsensical. If anything a priori is more like saying "the idea is true without evidence or experience because the evidence or experience is true because of the idea." The examples given for 'a priori' are based on acquired knowledge and therefore 'a posteriori.' For example, if you don't know what triangle means or what it is, you cannot 'know if it has three sides or what color it is. If you haven't been informed what bachelor means then you cannot know a bachelor is single. If you have not observed Bob, Jane or Sue you cannot conclude the statement is true till you have observed all three of them. So these are bad examples. In reverse, the statement of bachelors are unhappy is an assumption making it an a priori claim and a false sweeping statement. Bob is six feet tall is also an assumption till it is able to be observed and he is measured and until observed saying 'the triangle is blue' does not make it true as it can just as easily be red or some other color so again its an assumption without proof one way or the other.

    "The standard meter bar in paris is one meter long"
    It's logically true only in language, so it is analytic.
    But it's not A priori or Necessary, as it might not actually be one meter long right now.
    The claim can not be known to be true only by thinking, if it can also be thought as false. Method of proof for the bar to be one meter long is not strong enough.
    There might be confusion as this refers to "The" standard meter bar. Not to a bar that's necessarily one meter long right now, but to a bar that once was one meter long, but can not be logically proved to be still one meter long, in the real world, and therefore has to be measured again.
    Our reality won't collapse / turn into a big paradox if "The standard meter bar" is not actually one meter = contingent + when you can think this = A posteriori
    Something can be contingent and a priori, but it can not be thought to be contingent and a priori. It's contingency is argument against it's necessity and if it can be thought to be not necessarily true, how can it be thought to be true?

    If I have never seen a crow before and I look up the word crow in the dictionary and it defines it as a black feathered bird, then all crows are black is a priori just like saying all bachelors are single is a priori. It’s part of the definition of a crow. So, why do you claim all crows are black is a posteriori when there is no such thing as an non-black crow? By definition, crows are black just like bachelors are single. I would not know all bachelors are single unless I looked the word “bachelor” up in the dictionary. One could then say it was my experience of looking the word bachelor up in the dictionary and discovering it’s meaning that now makes the phrase “all bachelors are single” a posteriori, right?
