To me "wisdom" implies the ability to bring to bear appropriate knowledge at the appropriate time. I don't thing there is anything "in" the knowledge that makes the knower wise.
People talk of "deeper" truths, which implies that someone who is wise has access to different bits of knowledge (the deeper ones) than others who don't.
I don't really think this is how it works. Someone who is wise, because for example they have more life experience, has merely collected more knowledge that is appropriate to the questions or problems being posed.
I'm not disputing that wisdom involves the way we use the knowledge that we have as well as the quantity of knowledge, but that is different from saying that there is something inherently different about the knowledge.
Does a wise person really know a different type of proposition is true compared to a less wise person? That would be an interesting discussion point I think.
There is more to wisdom than what is known, there are skills possessed by the wise that aren't possessed by the less wise, but these skills don't constitute propositional knowledge, which is what I am trying to explore here.
Would you say that to be classified as wise a person needs "emotional intelligence", i.e. they have to be more "self aware". If we do think that wisdom implies a different type of propositional knowledge then what what are those types of propositions?
