Was Gödel the first person to pose and solve this question in mathematics? In the larger philosophical debate, has this question been posed before? Say by Plato or Aristotle?
One could interpret for example the famous statement by Horatio to Hamlet in this vein:
There are more things in heaven and earth than is dreamt of in your philosophy
That is there are more true things than can be grasped by philosophy.
But I'm looking for similar statements or positions within the Western Philosophical Tradition. The Eastern obviously has the Dao and Zen which has been epistemologically understood in this way.
