    My favorite deduction vs induction is:
    All people are mortal, I am a person therefore I am mortal.
    Vs
    In all my days of life I have not died, therefore I am immortal.

    Flawed? Probably. But it amuses me

    In some science people are given a fake and a real and it produces an effect…when life tries to give you a fake so you could manifest a drawback it cant if you have experience….experience will tell you if something is true.there is science and life pills that can produce an effect so real that i can be just as effective as truth or science otherwise science is deduction and meant to apply with personal wisdom since it couldnt be replicated since the event would have tp be 100 percent identical

    Persuasion and Conviction – are used in argumentations. Persuasion appeals to the emotion and seeks to produce action. Conviction appeals to mainly logical reasons and seeks to move the mind. Example: Public service campaigns that urges people to recycle or quit smoking.

    argumentation – is that form of discourse by means of which we try to persuade others about the truth or falsity of a disputed matter.

    Argumentation forms:

    Toulmin argument is often to assemble the strongest evidence in support of the claims being made.

    Propaganda

    – the process of pressuring someone into adopting radically different beliefs by using systematic and often forcible means

    example: Authoritarian Countries Brainwash their people from radical propaganda

    Propaganda presents only one side of a proposition and is sustained, organized attempt to make others accept an opinion or decision. Propaganda may be bad or good depending on the aim. Example: An ad that promotes a brand over the other.

    I invite the fellow amateur philosophers of YouTube to look into Mohamed Baqir Al-Sadr, the Shi'ite Iraqi Islamic philosopher who died under Saddam Hussein's regime. He's arguably the greatest or one of the greatest philosophers after Aristotle. Ever since Aristotle's time, induction was rejected as a valid method of reaching certainty and truth. Many thinkers and philosophers after Aristotle tried to prove the method of induction but failed to adequately do so. Mohamed Baqir Al-Sadr was the first to adequately prove it as a valid method of coming to certainty in order to prove the existence of God. There's a statue of him in Moscow, Russia, although it's sad not many people know of him. He was executed under Saddam's regime due to him being anti-socialist/communist and pro shi'ite-islamic theocracy. Being that Saddam's baathist regime was socialist, he was executed by saddam (but not before seeing his sister violated and tortured right before his eyes – true story.) He advanced Islamic philosophy a great deal.

    When we use deductive reasoning, aren't we deducing from premises that are held to be "true" based on inductive reasoning? For example, "all men are mortal" is considered a fact because all men that have been observed thus far have been mortal. That does not mean for certain that the next man who is born will be mortal.

    Everything seems to me to be doubtable, or at least anything that can be expressed in language. I cannot doubt that at this moment "something" is happening, but precisely what that something is can be doubted. Even the statement "I exist" can be doubted as it presupposes a subject called "I" that is doing something called "exist".

    Now, for all intents and purposes I live life as though these things are true, but that does not mean they are absolutely, eternally true.

    0:40 induction – slight dip in music
    0:55 induction is not certain – very notable dip in music
    1:04 induction adjust to counter evidence + transition to different conversation – music goes up
    1:25 the difference between deduction and induction is that deduction is complete – aka – "induction is incomplete"(I just deduced that) – slight drop in music

    From these observations about multiple points where the video is ingenious I am going to induce that this channel is genious. Subscribed.

    Another false dichotomy by and for the average shallow thinker, misleading by way of stultifying simplifications, inevitably confusing rather than clarifying thought. Deduction and Induction are simply two sides of the same coin. Try stopping your mind from using both in solving any given problem, consciously and/or unconsciously.

    It's very telling about human ability to understand the world and ourselves, that so few seem able to spontaneously get past such self-inflicted cognitive limitations. Rather bask in the perceived intellectual glory of fancy terms and consensus, irrationalities notwithstanding – than suffer the lonely pain of trying to really understand.

    Well done in under two minutes… “God has given us rational minds for this purpose, to penetrate all things, to find truth. If one renounce reason, what remains?” ~ Abdu'l-Bahá, Baha'i Faith

    There must be some fanboying going on here that I hadn't hereto encountered.

    Deduction is NOT complete, nor does it guarantee the truthfulness of the conclusion drawn from the premises; because premises MUST have an inductive root. The conclusion of a deduction can be erroneous if one or more of the premises are erroneous. Premises themselves can rest on a correct (though not necessarily true) deduction, or a direct product of induction, otherwise misrepresented as a "self-evident truth." There are no self-evident truths, only commonly believed truths that have withstood innumerable inductive trials.

    The undue exaltation of deduction as superior to induction (when in reality it is merely the trivial logical operations applied to the products of induction), gives a dangerous impression of certainty to questions that should never, ever have certain answers.

    In short, deduction is the trivial operation that allows sloppy and unprincipled thinkers to erase nuance and proceed under a simplified world view.
