All authentic art is conceived at a sacred moment and nourished in a blessed hour; an inner impulse creates it, often without the artist being aware of it.

What the newer landscape artists see in a circle of a hundred degrees in Nature they press together unmercifully into an angle of vision of only forty-five degrees. And furthermore, what is in Nature separated by large spaces, is compressed into a cramped space and overfills and oversatiates the eye, creating an unfavorable and disquieting effect on the viewer.

I am not so weak as to submit to the demands of the age when they go against my convictions. I spin a cocoon around myself; let others do the same. I shall leave it to time to show what will come of it: a brilliant butterfly or maggot.

The artist should paint not only what he sees before him, but also what he sees within him. If, however, he sees nothing within him, then he should also refrain from painting that which he sees before him. Otherwise, his pictures will be like those folding screens behind which one expects to find only the sick or the dead.

I must stay alone and know that I am alone to contemplate and feel nature in full.

God is everywhere, in the smallest grain of sand.

I must stay alone and know that I am alone to contemplate and feel nature in full; I have to surrender myself to what encircles me, I have to merge with my clouds and rocks in order to be what I am.
