"Blinding ignorance does mislead us. O! Wretched mortals, open your eyes!"
About this Quote
The intent is evangelical, but for observation. Leonardo’s moral plea (“open your eyes!”) doubles as a methodological command: look again, measure again, distrust what you think you see. Coming from an artist, that matters. Painting trains perception; anatomy and engineering weaponize it. Leonardo lived at a hinge-point when Europe was renegotiating authority - from scripture and scholastic argument toward experiment, dissection, and geometry. His notebooks are full of impatience with bookish certainty, and this exclamation reads like a marginal note turned manifesto.
Subtext: ignorance isn’t innocent. It “misleads,” implying movement, direction, consequences. To be blind is to be steerable. Leonardo’s outrage lands not on the complexity of the world, but on our willingness to stop looking. The line’s power comes from its simplicity: it makes epistemology sound like survival.
