I have to say my memory on the exact beliefs of Hume are murky. IIRC he did still think that human cognition starts with neutral input data and processes its way to the most abstract concepts. Heidegger inverts this. The context, the use, and the meaning are already embedded in all of your experiences. You don't have "neutral input data".
This is also what he means by "thrownness". Our being-in-the-world, in particular the way things have meaning to us and are intelligable, is conditional on our use and our social context. Not the other way around. We never logically arrive at our context, we were always already "thrown" into it.
I think it's actually quite a profound conceptual shift, which is why Heidegger is so popular. He's still an asshole for writing so obscurely, though.
