Gorky and Kandinsky on Abstract Painting

From my growing collection of quotes on abstract art, here are two from painters whose work I admire:

"Abstract art is the emancipation of the mind." -- Arshile Gorky

"Of all the arts, abstract painting is the most difficult. It demands that you know how to draw well, that you have a heightened sensitivity for composition and color, and that you be a true poet. This last is essential." -- Wassily Kandinsky
