What I am after, above all, is expression.

The splitting up of color [as Impressionists did] brought the splitting up of form and contour . . . Everything is reduced to a mere sensation of the retina, but one which destroys all tranquility of surface and contour. Objects are differentiated only by the luminosity that is given them.

Seek for the boldest color possible, content is irrelevant.

I was driven on by.. A force which I see today as something alien to my normal life... so I have been no more than a medium as it were.

After a half-century of hard work and reflection the wall is still there.

Simple colours can affect the intimate feelings with all the more force because they are simple.

The arts have a development which comes not only from the individual but also from a whole acquired force, the civilization which precedes us. One cannot do just anything. A talented artist cannot do whatever he pleases. If he only used his gifts, he would not exist. We are not the masters of what we produce. It is imposed on us.
