    Isn't the knowledge that red is a color already based on experience? And knowing what a bachelor is also? Right now it seems to me that only knowledge like mathematics can be truly a priori. Or maybe I don't get it yet.

    but of course the line between those two is maybe not so clear, since to know "object is red ergo object has a color", one must first know what "red" and "color" are and that "red" is a color

    I’m tearful as heck right now because I’ve been wracking my brain trying to figure this out. Descartes was difficult too. Wish I’d seen this channel before. But I definitely subscribed because I have a D so far in my Philosophy class and need some serious help or they’re kicking me out of college. I’m eight credits away from graduating.

    I thought pursuing a degree at 53 years old was a good idea.. this class was a struggle.

    I enjoyed learning but it was a harsh blow seeing at midterm I have a D.

    Any specific will be appreciated. If this thread isn’t too old thank you

    After looking back at this video again, I have found a way to memorize the two: a POSTeriori is referring to things after the experience, or POST-experience. I think I have that right, I hope it helps others as well.

    Been trying to figure this out for the past 6 weeks in my philosophy class, if I pass, it is certainly because of this Yt channel; thank you kind and educated gentlemen.

    Question: What type of knowledge is required for the man playing Billiard, that he would know where/how to strike the White ball in order for it to hit the Black ball at such angle so it will cause the black ball to go the intended direction?
    A) A Priori knowledge or B) A Posteriori knowledge.

    While at first glance, it appears that a priori knowledge is independent of experience, how can one know, for example, that an a priori statement such as “A bachelor is an unmarried man” is a true statement without first learning from the world what both bachelor and unmarried mean? It appears that all a priori statements are dependent on pre-knowledge of the world from which the meanings of the concepts are derived. Only after absorbing ideas from the world can we make a priori statements seemingly independent of it.

    Equivocating 3+3=6 with ' all bachelor are unmarried' amounts to the claim that a priori claims are trivial. Kant drew a pretty important distinction between a priori claims and claims that are tautologous, essentially, a priori claims must be substantive, they must indicate something about the nature of cogntition
