"If it is the love of that which your work represents--if, being a landscape painter, it is love of hills and trees that moves you--if, being a figure painter, it is love of human beauty, and human soul that moves you--if, being a flower or animal painter, it is love, and wonder, and delight in petal and in limb that move you, then the Spirit is upon you, and the earth is yours, and the fullness thereof."
