I have read on many sites online, like Reddit and Goodreads, the following quote supposedly from da Vinci's notebooks:
“Principles for the Development of a Complete Mind: Study the science of art. Study the art of science. Develop your senses- especially learn how to see. Realize that everything connects to everything else.”
― Leonardo da Vinci
And I have even tried to find sources for the original Italian text but was a bit limited to my knowledge of Italian. However, it does seem to be quoted in documents like this one from a museum dedicated to him: https://www.leonardoagradisca.it/wp-content/uploads/2019/12/catalogo_mddleonardo_en.pdf
"Per sviluppare una mente completa studia la scienza dell'arte, studia l'arte della scienza. Sviluppa i tuoi sensi, impara soprattutto a vedere. Comprendi che tutto è connesso."
Leonardo Da Vinci
But it really seems unclear where this quote comes from even though it is attributed to da Vinci. Are there any reliable references in Italian that can be used to verify this attribution?
