These principles [in art], forgotten over time, were rediscovered by a few geniuses such as Rembrandt, Vélazquez, Délacroix, Corot and Manet. These p… - Paul Sérusier

Brother Nabi - to a philosophical letter [he received from Denis ] a philosophical answer.. .[but] first of all, forgive the incoherence of my last letter. I am feeling remorsed about what I told you about Gauguin. There is no humbug about him, not, at any rate, with respect to those he knows are capable of understanding him. I have lived with him for the past fifteen days in the closest association [in Pont-Aven]. We share a room. I have told him what I dislike about his work; what I said can be regarded as a sally against the ingrained habits of contemporary painting. But let's go back to our philosophy.. ..(a:) Immutable principles exist in art. There is a science, namely aesthetics, that teaches them. Today this science is dead.

The painter ought not to rest until he has given birth to the child of his imagination.. ..begotten in a union of his mind with reality.
