source of Hamlet: "more things in heaven and earth Than dreamt of in your philosophy"

[TaTo]

Does anyone know if this line is an allusion to (paraphrase of) an older line from the Bible, Greek or Roman drama, etc.?

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

If I can recall correctly, It is not meant as an allusion, but only as a remark that there are more things and meanings in the world than that of the ideas of Horatio. I think, lol.

Hi. Thanks for the comment.

Hamlet sounds so sure -- sounds like he's quoting.

Yes, But in Shakespeare, the intellect of most his characters were strong speakers and therefore most often sure which thought/emotion to express in or at a certain time.
