"Hegel understood the Heisenbergian reality of knowing: yes, it would be nice if we could somehow delicately capture the truth and bring it closer to ourselves without altering it, "like a bird caught with a limestick." But the reality is, every truth we manage to know is altered, deformed by our very "encheiresis naturae," by the act of our taking-in-hand of nature (to borrow the alchemists' phrase from Goethe's Faust)."
