I studied philosophy through university...one of my favourites was learning about Frederick Dretske's concept of knowledge ascription--which he believed was context sensitive, and depending on the circumstance, we may need to elevate our 'contextual standard' in order to determine whether we have knowledge of a particular thing or not...it's deep, but it gets you thinking.

For an entertaining, shorter read, try Harry Frankfurt's essay "On Bullshit"
