"Although nature commences with reason and ends in experience it is necessary for us to do the opposite, that is to commence with experience and from this to proceed to investigate the reason"
About this Quote
The phrasing matters. “Nature commences with reason and ends in experience” suggests a world that is coherent underneath, a system whose logic cashes out in observable effects. But “it is necessary for us to do the opposite” admits a human limitation: we don’t get to see the blueprint. We approach reality from the outside, through sensory fragments, and only then build a model sturdy enough to be called “reason.” It’s an artist’s epistemology that doubles as proto-scientific method: sketch first, theorize second.
Context sharpens the intent. Leonardo lived amid a Renaissance hunger to reconcile classical authority with new forms of seeing: perspective, anatomy, hydraulics, flight. His notebooks read like a workshop where drawing is data collection. The subtext is almost polemical: if you want truth, stop auditioning clever explanations and start doing the work of looking. Experience isn’t inspiration here; it’s discipline, a demand that ideas earn their keep against the stubborn, measurable world.
