"I respect personality; it is an abstract entitity. A certain number of lines and colors constituting a harmony, can be arranged infinite ways. The literary side in painting is a second element of personality; it may exist – it must exist – but only as a pretext; if it dominates, one fall into the realm of illustration. You see that I do not wish to legislate personality."

“the impression of nature must be wedded to the aesthetic sentiment which chooses, arranges, simplifies and synthesizes. 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. Gauguin insisted on a logical construction of composition, on a harmonious apportionment of light and dark colors, the simplification of forms and proportions, so as to endow the outline's of forms with a powerful and eloquent expression.. ..He also insisted upon luminous and pure colors.”

“These principles , forgotten over time, were rediscovered by a few geniuses such as Rembrandt, Vélazquez, Délacroix, Corot and Manet. These principles can be deduced from innate principles within us, ideas of harmony, common to all unspoiled men.. ..these are the laws of harmony and color.”

“What part should nature play in a work of art? Where should the line be drawn? And from the standpoint of practical procedure - should one work directly from nature or merely study and remember it? Too much freedom frightens me, poor imitator that I am, and yet my head is filled with so many images evoked by what I see around me at all times that nature seems insignificant and banal.”

“The science , although it is not absolutely necessary, never hurts. It obviates much experimentation by trial and error, but one must, above all, not confuse it with skill. The first can be taught; the second must not be, and must even be combatted.. .What will necessarily happen to manual skill is.. if one neglects it, it becomes all the more clumsy and personal.”

“Brother Nabi - to a philosophical letter a philosophical answer.. . 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 . 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.. .. Immutable principles exist in art. There is a science, namely aesthetics, that teaches them. Today this science is dead. It was alive in the days of the beatific primitives...”
