The Notebooks of Leonardo da Vinci (1883), I Prolegomena and General Introduction to the Book on Painting
“My primary object is to defend and advance a principle in which I see the only possible relief from much that enthralls and degrades and distorts, turning light to darkness and good to evil, rather than to gage a philosopher or weigh a philosophy.

Context: We must do something to lead boys to look at the wonderful objects by which we are surrounded, and to examine them carefully. I don't think that lectures are of much use.

(original Dutch, citaat van B.C. Koekkoek:) Ik maak vooraf geene tekeningen van het voorwerp of de voorwerpen, die ik op het doek of paneel wil schilderen.. ..maar begin dadelijk het ontworpen plan op het doek te plaatsen – Na mijne compositie eerst behoorlijk geschetst en beredeneerd te hebben, voornamelijk de schikking van licht en donker, begin ik dezelve met olieverw breed te schilderen, zoveel trachtende de tint of het coloriet er in te brengen, in welke ik mijn landschap.. ..wil gezien hebben.. ..als het geheel afgeschilderd is.
