In Leonardo da Vinci's view, the process of human understanding of art and science is also "based on perceptual experience and the noblest feeling-vision", "all our knowledge comes from perception" and "painting is indeed a science and the legitimate daughter of nature".
It can be seen that Leonardo da Vinci's understanding of beauty is not only based on simple materialistic epistemology, but also has some characteristics that precede Descartes' "empiricism" epistemology, and this aesthetic thought also makes him accurately locate between reason and experience.
Leonardo da Vinci thought that "science is a general and practice is a soldier" and "what should a painter's heart be like? The painter's heart should be like a mirror, transforming itself into the color of objects and bringing it into the image of all objects in front of him truthfully. " This shows that he holds an empirical epistemology view on the preparatory stage of artistic creation.
