I think this is a pretty cool quote. I take it as common sense is something that you don't have often even if you are very knowledgeable. Yes you know where the movie theater is but do you know how to get there without being shot. Common sense is something though that I feel you gain with experience and is different from wisdom because you could just read about someone else's experience. Wisdom to me is really only a state of knowledge that makes you arrogant. So I think that what he was trying to say is that you can be wise but not smart with what you know. This applies to a lot of things. For instance, you could have a lot of money but you spend it all and can't hold on to a single dollar. Well when its time that you need something really important and you have no money left, you can't get it. But then there is going to be that person that saves half of their money every time they get a paycheck and then get hit by a truck and need to pay for the surgery on their back.
Coleridge is really interesting because what he takes in to considerations for his poems is that they are really universal. In any language someone could read this and get the same thing for the quote. I like what Coleridge does because it does not have to be a complex quote that only Rhode Scholars understand. Everything he says could be put into terms that could be explained even to a five year old.
Coleridge uses a lot of symbolism when he writes. In my prose poem Coleridge was one of my main inspirations because he writes with a style that is elegant but also intelligent. My prose poem ties into this because I feel that this is just as intelligent and elegant as my poem is.
