    this was the best video about logic I've seen so far thank you so much. Especially about soundness, so an argument to makes sense has to be sound. because it can work logically when it's a valid( or a tautology) but still making "no sense in the real world" because the premises are false. And finally all sound arguments are valid but not every valid argument is sound

      Sure! Maybe the person is just trying to give *evidence* that Mary has a pet penguin. The fact that Mary's pet is black and white _does_ increase the probability that it's a penguin. So, yeah-this argument could be construed as inductive. (But note that it would be a _weak_ inductive argument. The mere fact that Mary's pet is black and white does not make it probable, all things considered, that it's a penguin.)

    How'd i distinguish between an invalid deductive argument and inductive argument. Still dont quite get it

    • @LetsGetLogical
      @LetsGetLogical  Рік тому +2

      Insightful question! Assume the premises are true. And they make the conclusion probable but _not_ guaranteed. Is it a successful inductive argument or a failed deductive argument?
      Answer: it depends! If the argument is put forward with the aim of guaranteeing the conclusion, then it is an invalid deductive argument. But if the argument is put forward with the aim of making the conclusion probable, then it is a strong inductive argument.
      "Valid" and "strong" are terms of evaluation. But they're evaluating different things. So in the case you're talking about, if we ask "Is the reasoning any good?" the answer is: "Well, it's a good inductive argument (strong) but a bad deductive argument (invalid)."

      Great question. The precision you're asking about is exactly what the discipline of Statistics is for. But in the case of everyday inductive reasoning, it tends to be just common sense ball park estimates of probability, nothing precise.

    This video is misinforming the public. It is explaining deductive reasoning as taking two statements to gather a conclusion. That is INductive reasoning. Starting around 1:56.
    Deductive reasoning is taking the results to find the data. A breakdown into a conclusion. Inductive reasoning is a buildup into a conclusion; taking the data to find results.

    • @LetsGetLogical
      @LetsGetLogical  Рік тому +2

      @andrewvirtue5048 Thanks for dropping in. Appreciate your challenge. You sound like someone who is interested in this stuff, so I'd encourage you to take a look at some standard resources like the Stanford Encyclopedia of Philosophy or one of the common undergraduate-level logic books such as Hurley's A Concise Introduction to Logic, Copi's Introduction to Logic, or Herrick's Introduction to Logic (which is the text I use).
      I think you'll stand to benefit by comparing the view presented in these academic sources with your own view of inductive and deductive reasoning. Either by sharpening your own view, or coming to have a greater appreciation for how contemporary logicians frame these concepts. It's true the distinction can be characterized in different ways, but the characterization I give here is the most common.

    They are either cows or cats.
    There are not 9 cows in the barn.

Well, then it does _not_ follow logically that there is exactly 1 cat in the barn (because there are 0 cats in the barn). Or perhaps I misunderstood you.

      if the premise "There are not 9 cows in the barn." is false then tere must be 9 cows in the barn.
      so the conclusion has to be true that means the conclusion is guaranteed to be true if premise 1 and 2 are true and premise 3 is false.
      and since like you said the actual value of true or false does not matter, this argument should be valid. the 3rd premise is just negated and thats where my issue lies.
      just negate one premise and the definition of valid doesnt apply anymore

    • @LetsGetLogical
      @LetsGetLogical  2 роки тому +3

      @Gary Skinner, interestingly, there _are_ cogent and sound arguments for or against God's existence... we just don't know which ones they are! Here's what I mean: to identify an argument as cogent or sound, we must identify whether the premises are true or false. There are valid and strong arguments for and against God's existence-so the only remaining question is whether the claims put forward in the premises are actually true. If the premises put forward by the atheists are true, then they have cogent and sound arguments against God. If the premises put forward by the theists are true, then _they_ are the ones who have cogent and sound arguments _for_ God. But the premises are contested by both sides. So nobody knows which side in the debate has the cogent and sound arguments.
      This is a common situation in philosophy. It all comes down to a certain premise and it's an unsettled, open question whether that premise is true or false.

      @@LetsGetLogical yes I understand cojent and sound arguments, I absolutely don't know whether or not a god in fact exists, but the time to believe. Ie you think the proposition is true is when evidence points to such to justify the belief, I know people believe for good and bad reasons absolutely. I want to believe in as many true things as possible thus I'd like evidence which points to truth in reality with a small t.
      I know we can't ever be sure 100% of anything (brain in a vat) or life being a program, simulation etc, not that I advocate for this at all. We can only go with what we have at present. Furthermore athiests like me (not hard) don't claim to argue against a god I'm an agnostic atheist and thus I'm simply just not convinced with the conclusion that a god indeed exists, I'm not saying I know a god doesn't exist and therefore adopting the burden of proof.
      Simply I find the argument for God unconvincing atm unless I receive further information that sways me. Cheers bud ps soundness points to the premises being actually true that's what's missing in my view.
