“The sketch hunter moves through life as he finds it, not passing negligently the things he loves, but stopping to know them, and to note them down in the shorthand of his sketchbook.”

“I am always sorry for the Puritan, for he guided his life against desire and against nature. He found what he thought was comfort, for he believed the spirit's safety was in negation, but he has never given the world one minute's joy or produced one symbol of the beautiful order of nature. He sought peace in bondage and his spirit became a prisoner.”

“Through art mysterious bonds of understanding and of knowledge are established among men. They are the bonds of a great Brotherhood. Those who are of the Brotherhood know each other, and time and space cannot separate them. The Brotherhood is powerful. It has many members. They are of all places and of all times. The members do not die. One is member to the degree that he can be member, no more, no less. And that part of him that is of the Brotherhood does not die. The work of the Brotherhood does not deal with surface events. Institutions on the world surface can rise and become powerful and they can destroy each other. Statesmen can put patch upon patch to make things continue to stand still. No matter what may happen on the surface the Brotherhood goes steadily on. It is the evolution of man. Let the surface destroy itself, the Brotherhood will start it again. For in all cases, no matter how strong the surface institutions become, no matter what laws may be laid down, what patches may be made, all change that is real is due to the Brotherhood.”

“When the artist is alive in any person, whatever his kind of work may be, he becomes an inventive, searching, daring, self-expressive creature. He becomes interesting to other people. He disturbs, upsets, enlightens, and opens ways for better understanding. Where those who are not artists are trying to close the book, he opens it and shows there are still more pages possible.”

“You form a society: that limits you. Adopt a name, and you've limited yourself again; draw up a constitution and bylaws and you've made a groove, a rut, that hampers your growth. You think you can fix your course and move straight along it. But sometimes the important thing is to strike out sidewise.”

“Do whatever you do intensely. The artist is the man who leaves the crowd and goes pioneering. With him there is an idea which is his life.”

“If a certain activity, such as painting, becomes the habitual mode of expression, it may follow that taking up the painting materials and beginning work with them will act suggestively and so presently evoke a flight into the higher state.”
