This passage of Heidegger has been rolling around in my head all day.  It must be connected to something else I have on my mind.  Lord willing, I will eventually figure out what that is.

Thirst for knowledge and greed for explanations never lead to a thinking inquiry.  Curiosity is always the concealed arrogance of a self-consciousness that banks on a self-invented ratio and its rationality.  The will to know does not will to abide in hope before  what is worthy of thought.  –“A Dialogue on Language”
