Quote analysis

There are more things in heaven and earth, Horatio,Than are dreamt of in your philosophy. 


The emphasis here should be on "dreamt of", as Hamlet is pointing out how little even the most educated people can explain. One can imagine happier times when Hamlet and Horatio, studying together at Wittenberg, engaged in heated philosophical debates. In this quote Hamlet is speaking in general terms about the limitations of human thought.
